This disclosure features methods and compositions for treating diseases of the gastrointestinal tract with an IL-12/IL-23 inhibitor.
Interleukin-23 (IL-23) is a heterodimeric cytokine composed of an IL-12p40 subunit (that is shared with IL-12) and the IL-23p19 subunit. IL-23 is primarily produced by professional antigen-presenting cells (e.g., dendritic cells and macrophages) and monocytes in response to an infection with variety of bacterial and fungal pathogens. IL-23R is expressed on various adaptive and innate immune cells including Th17 cells, γδ T cells, natural killer (NK) cells, dendritic cells, macrophages, and innate lymphoid cells, which are found abundantly in the intestine. IL-23R and downstream effector cytokines have a primary role in disease pathogenesis of inflammatory bowel disease (IBD) in acute and chronic mouse models. In patients with IBD, gene expression and protein levels of IL-23R are elevated at the intestine mucosal surface. Without wishing to be bound by theory, it is believed that IL-23 mediates its pathogenic effects by promoting the development of a pathogenic CD4+ T cell population that produces IL-6, IL-17, and tumor necrosis factor (e.g., TNF-alpha).
Interleukin 12 (IL-12) is an interleukin that is naturally produced by a variety of cell types including macrophages, neutrophils, dendritic cells, and human B-lymphoblastoid cells (NC-37). It is a heterodimeric cytokine comprising four alpha helices that are encoded by two separate genes: IL-12A (p35) and IL-12B (p40). IL-12 plays a role in balancing T cell-mediated pro- and anti-inflammatory immune responses, and are thought to have a role in the regulation of intestinal homeostasis, and ultimately, the pathogenesis of inflammatory bowel disorders.
The gastrointestinal (GI) tract generally provides a therapeutic medium for an individual's body. One means of accessing the therapeutic medium of the GI tract is via oral administration, however, the convenience of per oral delivery is countered by well-established challenges. For instance, traditional oral delivery of a drug may lend itself to systemic exposure associated with undesirable or potentially harmful side effects. Another challenge associated with oral administration relates to potential instability of the drug upon exposure to the harsh chemical and/or enzymatic degradation conditions of the GI tract.
Yet at times, therapeutic drugs may need to be dispensed to specified locations within the small intestine or large intestine, which is more effective than traditional oral administration of the therapeutic drugs to cure or alleviate the symptoms of some medical conditions. For example, therapeutic drugs dispensed directly within the small intestine would not be contaminated, digested or otherwise compromised in the stomach, and thus allow a higher dose to be delivered at a specific location within the small intestine.
An effective way to provide topical, local delivery of a therapeutic drug to the GI tract (and/or to a particular portion or section of the GI tract) to treat the diseased tissue in the GI tract would be desirable, given the following advantages over systemic administration:
In practice, however, there are several challenges to such an approach. To begin with, identifying a “go/no-go” trigger for delivery to a specific site is generally difficult (e.g., see Rubenstein A., “Approaches and Opportunities in Colon-Specific Drug Delivery”; Critical Reviews in Therapeutic Drug Carrier Systems, 12(2&3), pp. 101-149 (1995), p. 106: “A successful delivery of a drug molecule to the colon means that most of it has been transported intact through the stomach and the small intestine. Practically, one cannot find a physiologic feature that may serve as a “go no-go” trigger for [delivery of] colonic-specific drugs”). For example, dispensing therapeutic drugs directly within the small intestine inside a human body (e.g., the cecum, the ascending colon) can be difficult, because a device or mechanism or a particular formulation would be needed to transport a therapeutically effective dose of drug to a desired location within the small intestine and then automatically deliver the therapeutic drug at the desired location. Such a device or mechanism would also need to be operated in a safe manner in that the device or mechanism needs to physically enter the human body. Dispensing therapeutic drugs directly within other locations in the GI tract of the human body can be similarly difficult. For diseased tissue in the colon, an added challenge lies in the difficulty in reaching the site of disease due to its location.
A further hurdle exists when the drug is a biologic, such as a monoclonal antibody, in which case there is a need to achieve high concentrations of the therapeutic drug in the large intestine for diseases such as, for example, colitis, and Crohn's disease [Van den Mooter et al., Drug Delivery (1996)]. Monoclonal antibodies (“mAbs”) are typically delivered in single doses, generally 100 mg to 1 g protein per dose; since formulations of mAbs typically have concentrations up to about 50 mg/mL, administration of a relatively high volume of 2-20 mL per dose is required [Yang et al., PNAS, 2003]. At the relatively high concentrations required to deliver efficacious doses, mAbs have a tendency to aggregate; in addition, these high concentrations often result in very high viscosity and poor overall stability [Yang et al.]. Increasing protein concentrations may also result in opalescence, complicating the visual inspection [Puhl et al., Asian J. Pharm. Sci. II (2016), pp. 469-477]. While the use of more dilute formulations may help overcome these drawbacks, the resulting large volumes may not be practical for oral delivery to treat diseases and conditions of the GI tract, and may instead be conducive to IV infusion—which, in turn, may enhance unwanted systemic exposure.
Methods typically employed to deliver drugs locally all have their own drawbacks. For example, the usefulness of formulations relying on pH-mediated release (including but not limited to enteric coated formulations) may be limited by the high inter- and intra-patient variability of pH and microflora. The utility may be further limited in patient populations having highly variable motility (e.g., patients with ulcerative colitis), contributing to unpredictable transit times (times for transitioning from one portion of the GI tract to an adjacent portion). For example, budesonide formulated using Multi Matrix (MMX®) colonic delivery technology (budesonide MMX®) is a once-daily oral tablet designed for controlled release of budesonide throughout the colon for the treatment of ulcerative colitis. The tablet relies on pH-mediated release. When 153Sm labelled budesonide MMX® tablets were administered to 12 healthy subjects and evaluated for initial tablet disintegration (ITD) within the GI tract via pharmaco-scintigraphy, high variability in the location and time of ITD were observed, ranging from release in the ileum or small intestine/ileum after 6 to 12 hours (4 subjects) to release in the sigmoid colon after greater than 24 h (1 subject) [Brunner M. et al., “Gastrointestinal transit, release and plasma pharmacokinetics of a new oral budesonide formulation,” Br. J. Clin. Pharmacol. (2006) 61(1), pp. 31-38]. Moreover, pH is dysregulated in ulcerative colitis patients, making MMX technology and other pH-dependent drug delivery technologies less predictable. Not only are release and emulsification of drug unpredictable, but such technologies also have poor compatibility with some preferred formulation systems, including emulsifying systems. Rectal delivery forms (suppositories and enemas) have varying effectiveness since here too high variability has been observed in the distribution of these forms. Suppositories are only effective in the rectum because of their confined spread, and enemas may offer effective topical treatment only to the sigmoid colon and descending colon [Van den Mooter et al., Drug Delivery (1996)].
Additional proposed solutions to colonic delivery, and some associated disadvantages, are described in Van den Mooter et al., Drug Delivery (1995). For example, attempts have been made to modify the release profile of drugs using pH-sensitive polymers or bacterial-degradable polymers as coatings. The use of pH-sensitive polymers, however, is characterized by the ‘unsteadiness’ of the site where the polymer disintegration commences—so that polymer dissolution can be completed at the end of the ileum or deep in the colon, depending on the intensity of GI motility. Colonic pH reduction (e.g., to as low as about pH 6, due to the presence of short-chain fatty acids, bile acid residues, CO2 or other fermentation products) can reduce the reliability of triggering drug release based on the colon pH. An additional disadvantage is the difficulty to formulate certain drugs in enteric coated delivery capsules. As for bacterial-degradable polymers, they suffer from variability in absorption rates, which may be attributed to intra- and inter-subject differences in microbial degradation of the coating. The same drawbacks apply to delivery of drugs through bacterial-degradable matrices.
Another approach involves the preparation of prodrugs of the therapeutic agent. This approach relies on selective cleavage of the prodrug to release the active form in the colon as a result of metabolic activity of the gut microflora. Once again, this approach relies on factors, such as the enzymatic activity in GI tract, that may be highly variable between and within subjects.
The use of non-autonomous devices and/or procedures could be seen as offering a potential solution to the foregoing problems, but in practice this approach too faces several challenges, such as:
In sum, there remains a significant unmet medical need for improved treatment regimens for gastrointestinal diseases, such as inflammatory bowel disease (IBD), including a need for regimens which can dispense therapeutics to specific locations within the GI tract, thereby reducing or avoiding the drawbacks of oral or other forms of systemic administration.
The present disclosure provides devices and methods for the topical administration of drug/mAbs to the GI tract, and more particularly, proximate to one or more disease sites.
The present disclosure provides one or more advantages:
The present disclosure provides novel treatment paradigms for inflammatory conditions of the gastrointestinal tract. The methods and compositions described herein allow for the regio-specific release of therapeutic drugs at or near the site of disease in the gastrointestinal tract. By releasing a therapeutic drug locally instead of systemically, the bioavailability of the drug can be increased at the site of injury and/or decreased in the systemic circulation, thereby resulting in improved overall safety and/or efficacy and fewer adverse side effects. Advantages can include one or more of increased drug engagement at the target, leading to new and more efficacious treatment regimens, and/or lower systemic drug levels, which can translate to reduced toxicity and reduced immunogenicity, e.g., in the case of biologics. In some instances, releasing a therapeutic drug locally also provides for new modes of action that may be unique to local delivery in the GI tract as opposed to systemic administration. For patients, clinicians and payors, this can mean an easier or simpler route of administration, fewer co-medicaments (e.g., immunomodulators), fewer side effects, and/or better outcomes.
For example, a patient may present to a physician with one or more symptoms of a disorder of the GI tract (e.g., inflammatory bowel disease), and the physician can determine the specific discrete location(s) of diseased tissue (e.g., inflamed tissue or a lesion) in the patient's GI tract, and then use any of the devices described herein to topically administer a therapeutically effective amount of an IL-12/IL-23 inhibitor proximate to or directly onto the specific discrete location(s) of diseased tissue in the patient.
In other examples, a patient may present to a physician with one or more symptoms of a disorder of the GI tract (e.g., inflammatory bowel disease) and the physician can use any of the devices provided herein to identify the specific discrete location(s) of diseased tissue (e.g., inflamed tissue or a lesion) in the patient's GI tract, and then use the same device or a different device (e.g., any of the devices described herein) to topically administer a therapeutically effective amount of an IL-12/IL-23 inhibitor proximate to or directly onto the specific discrete locations of diseased tissue in the patient. In some embodiments, a therapeutically effective amount of an IL-12/IL-23 inhibitor is administered to a section or subsection of the GI tract containing one or more disease sites. In some embodiments, a therapeutically effective amount of an IL-12/IL-23 inhibitor is administered proximal to a section or subsection of the GI tract containing one or more disease sites.
As can be appreciated by those in the art, these methods may be performed periodically on a patient at periodic intervals, e.g., approximately twice a month, approximately once a month, approximately every two months, approximately every three months, approximately four months, approximately five months, or approximately every six months. In some examples, these methods can provide for increased efficacy of treatment (e.g., reduced negative side effects and/or increased reduction in the severity, frequency, or number of symptoms) as compared to a patient which is administered an oral dosage form of the same IL-12/IL-23 inhibitor. In some embodiments, the dosage of the IL-12/IL-23 inhibitor administered using any of the devices described herein can differ between the different clinical visits based on an observation or measurement of the severity of disease at the specific discrete location(s) of diseased tissue (e.g., inflamed tissue or a lesion) in the patient's GI tract at the time of each clinical visit, or based on one or more observations or measurements of systemic disease markers (e.g., inflammatory markers in the blood) or markers in stool (e.g., calprotectin and lactoferrin). In some examples, over time, new specific discrete location(s) of diseased tissue may be detected or observed in the patient, and any of the devices described herein can be used to administer a therapeutically effective amount of an IL-12/IL-23 inhibitor onto or proximal to the new specific discrete location(s) of diseased tissue in the patient's GI tract.
In some examples, the identification of the specific discrete location(s) of diseased tissue (e.g., inflamed tissue or a lesion) in the patient's GI tract and the administration of a therapeutically effective amount of an IL-12/IL-23 inhibitor using any of the devices described herein can be performed in a single clinical visit.
In some examples, the diagnosis of a disorder of the GI tract (e.g., inflammatory bowel disease), the identification of the specific discrete location(s) of diseased tissue (e.g., inflamed tissue or a lesion) in the patient's GI tract, and the topical administration of a therapeutically effective amount of an IL-12/IL-23 inhibitor proximate to or directly onto the specific discrete locations of diseased tissue in the patient using any of the devices described herein, can be performed in a single clinical visit.
Accordingly, described herein are methods for treating disorders of the gastrointestinal (GI) tract. The methods can include one or more of:

Any details or embodiments described for a device apply equally to methods of treatment using the device, or to an IL-12/IL-23 inhibitor or composition for use in a method of treatment involving the device.
The present disclosure is directed to various methods and formulations for treating diseases of the gastrointestinal tract with an IL-12/IL-23 inhibitor. For example, in an embodiment, a method of treating a disease of the gastrointestinal tract in a subject comprises administering to the subject a pharmaceutical formulation comprising an IL-12/IL-23 inhibitor wherein the pharmaceutical formulation is released in the subject's gastrointestinal tract proximate to one or more sites of disease. For example, in an embodiment, the pharmaceutical formulation comprises a therapeutically effective amount of an IL-12/IL-23 inhibitor.
In some embodiments, the formulation is contained in an ingestible device, and the device releases the formulation at a location proximate to the site of disease. The location of the site of disease may be predetermined. For example, an ingestible device, the location of which within the GI tract can be accurately determined as disclosed herein, may be used to sample one or more locations in the GI tract and to detect one or more analytes, including markers of the disease, in the GI tract of the subject. A pharmaceutical formulation may be then administered via an ingestible device and released at a location proximate to the predetermined site of disease. The release of the formulation may be triggered autonomously, as further described herein.
The following disclosure illustrates aspects of the formulations and methods embodied in the claims.
As used herein, a “formulation” of an IL-12/IL-23 inhibitor may refer to either the IL-12/IL-23 inhibitor in pure form, such as, for example, a lyophilized IL-12/IL-23 inhibitor, or a mixture of the IL-12/IL-23 inhibitor with one or more physiologically acceptable carriers, excipients or stabilizers. Thus, therapeutic formulations or medicaments can be prepared by mixing the IL-12/IL-23 inhibitor having the desired degree of purity with optional physiologically acceptable carriers, excipients or stabilizers (Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980)), in the form of lyophilized formulations or aqueous solutions. Acceptable carriers, excipients, or stabilizers are nontoxic to recipients at the dosages and concentrations employed, and include buffers such as phosphate, citrate, and other organic acids; antioxidants including ascorbic acid and methionine; preservatives (such as octadecyldimethylbenzyl ammonium chloride; hexamethonium chloride; benzalkonium chloride, benzethonium chloride; phenol, butyl or benzyl alcohol; alkyl parabens such as methyl or propyl paraben; catechol; resorcinol; cyclohexanol; 3-pentanol; and m-cresol); low molecular weight (less than about 10 residues) antibody; proteins, such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino acids such as glycine, glutamine, asparagine, histidine, arginine, or lysine; monosaccharides, disaccharides, and other carbohydrates including glucose, mannose, or dextrins; chelating agents such as EDTA; sugars such as sucrose, mannitol, trehalose or sorbitol; salt-forming counter-ions such as sodium; metal complexes (e.g., Zn-protein complexes); and/or non-ionic surfactants such as TWEEN™, PLURONICS™ or polyethylene glycol (PEG).

Certain exemplary sHASEGPs and methods of use, including rHuPH20, are described in US Patent Publication Nos. 2005/0260186 and 2006/0104968. In one aspect, a sHASEGP is combined with one or more additional glycosaminoglycanases such as chondroitinases. Exemplary lyophilized formulations are described in U.S. Pat. No. 6,267,958. Aqueous formulations include those described in U.S. Pat. No. 6,171,586 and WO2006/044908, the latter formulations including a histidine-acetate buffer.
A formulation of an IL-12/IL-23 inhibitor as disclosed herein, e.g., sustained-release formulations, can further include a mucoadhesive agent, e.g., one or more of polyvinyl pyrrolidine, methyl cellulose, sodium carboxyl methyl cellulose, hydroxyl propyl cellulose, carbopol, a polyacrylate, chitosan, a eudragit analogue, a polymer, and a thiomer. Additional examples of mucoadhesive agents that can be included in a formulation with an IL-12/IL-23 inhibitor are described in, e.g., Peppas et al., Biomaterials 17(16):1553-1561, 1996; Kharenko et al., Pharmaceutical Chemistry J. 43(4):200-208, 2009; Salamat-Miller et al., Adv.

Accordingly, in some embodiments of the method of treating a disease as disclosed herein, the method comprises administering to the subject a pharmaceutical composition that is a formulation as disclosed herein. In some embodiments the formulation is a dosage form, which may be, as an example, a solid form such as, for example, a capsule, a tablet, a sachet, or a lozenge; or which may be, as an example, a liquid form such as, for example, a solution, a suspension, an emulsion, or a syrup.
In some embodiments, the formulation is not comprised in an ingestible device. In some embodiments wherein the formulation is not comprised in an ingestible device, the formulation may be suitable for oral administration. The formulation may be, for example, a solid dosage form or a liquid dosage form as disclosed herein. In some embodiments wherein the formulation is not comprised in an ingestible device, the formulation may be suitable for rectal administration. The formulation may be, for example, a dosage form such as a suppository or an enema. In embodiments where the formulation is not comprised in an ingestible device, the formulation releases the IL-12/IL-23 inhibitor at a location in the gastrointestinal tract of the subject that is proximate to one or more sites of disease. Such localized release may be achieved, for example, with a formulation comprising an enteric coating. Such localized release may be achieved, an another example, with a formulation comprising a core comprising one or more polymers suitable for controlled release of an active substance. A non-limiting list of such polymers includes: poly(2-(diethylamino)ethyl methacrylate, 2-(dimethylamino)ethyl methacrylate, poly(ethylene glycol), poly(2-aminoethyl methacrylate), (2-hydroxypropyl)methacrylamide, poly(β-benzyl-1-aspartate), poly(N-isopropylacrylamide), and cellulose derivatives.
In some embodiments, the formulation is comprised in an ingestible device as disclosed herein. In some embodiments wherein the formulation is comprised in an ingestible device, the formulation may be suitable for oral administration. The formulation may be, for example, a solid dosage form or a liquid dosage form as disclosed herein. In some embodiments the formulation is suitable for introduction and optionally for storage in the device. In some embodiments the formulation is suitable for introduction and optionally for storage in a reservoir comprised in the device. In some embodiments the formulation is suitable for introduction and optionally for storage in a reservoir comprised in the device. Thus, in some embodiments, provided herein is a reservoir comprising a therapeutically effective amount of an IL-12/IL-23 inhibitor, wherein the reservoir is configured to fit into an ingestible device. In some embodiments, the reservoir comprising a therapeutically effective amount of an IL-12/IL-23 inhibitor is attachable to an ingestible device. In some embodiments, the reservoir comprising a therapeutically effective amount of an IL-12/IL-23 inhibitor is capable of anchoring itself to the subject's tissue. As an example, the reservoir capable of anchoring itself to the subject's tissue comprises silicone. As an example, the reservoir capable of anchoring itself to the subject's tissue comprises polyvinyl chloride.
In some embodiments the formulation is suitable for introduction in a spray catheter, as disclosed herein.
The formulation herein may also contain more than one active compound as necessary for the particular indication being treated, for example, those with complementary activities that do not adversely affect each other. For instance, the formulation may further comprise another IL-12/IL-23 inhibitor or a chemotherapeutic agent. Such molecules are suitably present in combination in amounts that are effective for the purpose intended.
The active ingredients may also be entrapped in microcapsules prepared, for example, by coacervation techniques or by interfacial polymerization, for example, hydroxymethylcellulose or gelatin-microcapsule and poly-(methyl methacrylate) microcapsule, respectively, in colloidal drug delivery systems (for example, liposomes, albumin microspheres, microemulsions, nanoparticles and nanocapsules) or in macroemulsions. Such techniques are disclosed in Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980).
The formulations to be used for in vivo administration must be sterile. This is readily accomplished by filtration through sterile filtration membranes.
Sustained-release preparations may be prepared. Suitable examples of sustained-release preparations include semipermeable matrices of solid hydrophobic polymers containing the IL-12/IL-23 inhibitor, which matrices are in the form of shaped articles, e.g., films, or microcapsule. Examples of sustained-release matrices include polyesters, hydrogels (for example, poly(2-hydroxyethyl-methacrylate), or poly(vinylalcohol)), polylactides (U.S. Pat. No. 3,773,919), copolymers of L-glutamic acid and γ ethyl-L-glutamate, non-degradable ethylene-vinyl acetate, degradable lactic acid-glycolic acid copolymers such as the LUPRON DEPOT™ (injectable microspheres composed of lactic acid-glycolic acid copolymer and leuprolide acetate), and poly-D-(−)-3-hydroxybutyric acid. While polymers such as ethylene-vinyl acetate and lactic acid-glycolic acid enable release of molecules for over 100 days, certain hydrogels release proteins for shorter time periods. When encapsulated IL-12/IL-23 inhibitors remain in the body for a long time, they may denature or aggregate as a result of exposure to moisture at 37° C., resulting in a loss of biological activity and possible changes in immunogenicity. Rational strategies can be devised for stabilization depending on the mechanism involved. For example, if the aggregation mechanism is discovered to be intermolecular S—S bond formation through thio-disulfide interchange, stabilization may be achieved by modifying sulfhydryl residues, lyophilizing from acidic solutions, controlling moisture content, using appropriate additives, and developing specific polymer matrix compositions.
Pharmaceutical formulations may contain one or more IL-12/IL-23 inhibitors. The pharmaceutical formulations may be formulated in any manner known in the art. In some embodiments the formulations include one or more of the following components: a sterile diluent (e.g., sterile water or saline), a fixed oil, polyethylene glycol, glycerin, propylene glycol, or other synthetic solvents, antibacterial or antifungal agents, such as benzyl alcohol or methyl parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like, antioxidants, such as ascorbic acid or sodium bisulfate, chelating agents, such as ethylenediaminetetraacetic acid, buffers, such as acetates, citrates, or phosphates, and isotonic agents, such as sugars (e.g., dextrose), polyalcohols (e.g., mannitol or sorbitol), or salts (e.g., sodium chloride), or any combination thereof. Liposomal suspensions can also be used as pharmaceutically acceptable carriers (see, e.g., U.S. Pat. No. 4,522,811, incorporated by reference herein in its entirety). The formulations can be formulated and enclosed in ampules, disposable syringes, or multiple dose vials. Where required, proper fluidity can be maintained by, for example, the use of a coating, such as lecithin, or a surfactant. Controlled release of the IL-12/IL-23 inhibitor can be achieved by implants and microencapsulated delivery systems, which can include biodegradable, biocompatible polymers (e.g., ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid; Alza Corporation and Nova Pharmaceutical, Inc.).
In some embodiments, the IL-12/IL-23 inhibitor is present in a pharmaceutical formulation within the device.

Methods of Making Aqueous Formulations
Skilled practitioners will appreciate that any number of methods may be used to make an aqueous formulation. Methods of making aqueous formulations, as disclosed in US 2009/0291062 and U.S. Pat. No. 8,420,081, may be based on a diafiltration process wherein a first solution containing a protein is diafiltered using water as a diafiltration medium. Protein production operations often involve final diafiltration of a protein solution into a formulation buffer once the protein has been purified from impurities resulting from its expression. For example, an aqueous formulation may be made by subjecting a protein solution to diafiltration using water alone as a diafiltration solution. Proteins may be transferred into pure water for use in a stable formulation, wherein the protein remains in solution and can be concentrated at high levels without the use of other agents to maintain its stability. Diafiltration uses membranes to remove, replace, or lower the concentration of salts or solvents from the protein solutions. Diafiltration or diafiltration/ultrafiltration (DF/UF) selectively utilizes permeable (porous) membrane filters to separate the components of solutions and suspensions based on their molecular size. One parameter for selecting a membrane for concentration is its retention characteristics for the sample to be concentrated. To assure complete retention, the molecular weight cut-off (MWCO) of the membrane should be about ⅓rd to about ⅙th of the molecular weight of the molecule to be retained. In order to prepare a low-ionic protein formulation, the protein solution (which may be solubilized in a buffered formulation) is subjected to a DF/UF process, whereby water is used as a DF/UF medium. In some embodiments, the DF/UF medium consists of water and does not include any other excipients. Any water can be used in the DF/UF process, although particularly useful water is purified or deionized water. The process may be performed such that there is at least a determined volume exchange, e.g., a five-fold volume exchange, with the water. The resulting aqueous formulation has a significant decrease in the overall percentage of excipients in comparison to the initial protein solution. For example, 95-99% less excipients may be found in the aqueous formulation in comparison to the initial protein solution. Despite the decrease in excipients, the protein can remain soluble and retain its biological activity, even at high concentrations. In some embodiments, the methods of the present disclosure result in compositions comprising an increase in concentration of the protein while decreasing additional components, such as ionic excipients. As such, the hydrodynamic diameter of the protein in the aqueous formulation is smaller relative to the same protein in a standard buffering solution, such as phosphate buffered saline (PBS). Methods may include diafiltering a protein solution using water as a diafiltration medium and subsequently concentrating the resulting aqueous solution. Concentration following diafiltration results in an aqueous formulation containing water and an increased protein concentration relative to the first protein solution. Concentration of the diafiltered protein solution may be achieved through means known in the art, including centrifugation. There are two forms of DF/UF, including DF/UF in discontinuous mode and DF/UF in continuous mode. Useful methods described herein may be performed according to either mode.
In some embodiments, the first protein solution is subjected to a repeated volume exchange with the water, such that an aqueous formulation, which is essentially water and protein, is achieved. The diafiltration step may be performed any number of times, depending on the protein in solution, wherein one diafiltration step equals one total volume exchange. As a result of the diafiltration methods, the concentration of solutes in the first protein solution is significantly reduced in the final aqueous formulation comprising essentially water and protein. For example, the aqueous formulation can have a final concentration of excipients which is at least 95% less than the first protein solution, for example, at least 99% less than the first protein solution. For example, in one embodiment, to dissolve a protein in WFI is a process that creates a theoretical final excipient concentration, reached by constant volume diafiltration with five diafiltration volumes, that is equal or approximate to Ci e=0.00674, i.e., an approximate 99.3% maximum excipient reduction.
The terms “excipient-free” or “free of excipients” indicate that the formulation is essentially free of excipients. In some embodiments, excipient-free indicates buffer-free, salt free, sugar-free, amino acid-free, surfactant-free, and/or polyol free. In some embodiments, the term “essentially free of excipients” indicates that the solution or formulation is at least 99% free of excipients. It should be noted, however, that in certain embodiments, a formulation may comprise a certain specified non-ionic excipient, e.g., sucrose or mannitol, and yet the formulation is otherwise excipient free. For example, a formulation may comprise water, a protein, and mannitol, wherein the formulation is otherwise excipient free. In another example, a formulation may comprise water, a protein, and polysorbate 80, wherein the formulation is otherwise excipient free. In yet another example, the formulation may comprise water, a protein, a sorbitol, and polysorbate 80, wherein the formulation is otherwise excipient free.
In some embodiments, certain characteristics of the formulation may be adjusted, such as the osmolality and/or viscosity, as desired in high protein concentration-water solutions, by adding non-ionic excipients (e.g., mannitol) without changing other desired features, such as non-opalescence. As such, either during or following the transfer of the protein to water or during the course of the diafiltration, excipients may be added that improve, for example, the osmolality or viscosity features of the formulation. Such non-ionic excipients could be added during the process of the transfer of the protein into the final low ionic formulation. Examples of non-ionizable excipients that may be added to the aqueous formulation for altering desired characteristics of the formulation include, but are not limited to, mannitol, sorbitol, a non-ionic surfactant (e.g., polysorbate 20, polysorbate 40, polysorbate 60 or polysorbate 80), sucrose, trehalose, raffinose, and maltose.
In some embodiments, a liquid formulation can be a solution or suspension prepared in a suitable aqueous solvent, e.g., water or aqueous/organic mixture, such as a water/alcohol mixture. Liquid formulations may be refrigerated (e.g., 2-8° C.) or frozen (e.g., at −20° C. or −80° C.) for storage.
In some embodiments, the present disclosure provides a method for generating a high concentration, aqueous protein suspension preparation, wherein proteins can be therapeutic antibodies. The suspension comprises a protein and a polyamino acid, which serves as a precipitant. The protein and polyamino acid (e.g., poly-L-lysine or poly-L-glutamic acid) form a complex at low ionic strength that is suspended in the buffer. In one example, proteins at about 1.0 mg/mL to about 200 mg/mL are fully precipitated by the addition of about 0.05-0.3 mg/mL poly(amino acid). The protein is stabilized and can be concentrated by removing water or supernatant from the aqueous suspension, for example, following centrifugation of the precipitates. The precipitates are then dissolved by addition of a buffer with salt, for example, at physiological ionic strength of 150 mM sodium chloride (NaCl).
These methods result in redissolved proteins that retain the original activity and native secondary structure of the protein. Also, the method of the present disclosure eliminates the need for the addition of additives that may be necessary for other formulations. In some embodiments, the suspension preparation does not need a dissolving step. The preparation method also has the advantage of producing a concentrated suspension with a relatively low viscosity as compared to other high concentration protein formulations. Exemplary methods and preparations for generating high concentration protein formulations via precipitation and re-dissolution using polyamino acid are described, for example, in US application publication No. 2016/0206752 and Kurinomaru, Takaaki, et al., “Protein-poly (amino acid) complex precipitation for high-concentration protein formulation,” Journal of Pharmaceutical Sciences 103.8 (2014):2248-2254, the disclosure of which is incorporated herein by reference in its entirety.

In some embodiments, the drug is provided as a lyophilized powder or in extruded form. In one embodiment, the solid drug formulation comprises, consists of or consists essentially of the antibody.
In the case of such solid formulations, such as powders (e.g., for direct incorporation into a device as disclosed herein, or for the preparation of solutions for incorporation into a device as disclosed herein), useful methods of preparation are vacuum drying and freeze-drying that yields a powder of the antibody plus any additional desired ingredient from a previously prepared solution thereof. In some embodiments, a solid formulation (e.g., in a dried state) can be stable for at least three months at about 40° C. and 75% relative humidity (RH). A solid formulation may also have a moisture content of no more than about 5%, about 4.5%, about 4%, about 3.5%, about 3%, about 2.5%, about 2%, about 1.5%, or about 1%; or the solid formulation is substantially anhydrous.

In some embodiments, an amount of a free amino acid (and/or salt thereof) in a dry, (e.g., lyophilized) formulation can be in the range from about 1% to about 10% (w/w of dry formulation), or from about 3% to about 6% (w/w). In some embodiments, an amount of amino acid in a dry, (e.g., lyophilized) formulation can be greater than about 4% (w/w of the dry formulation) when the antibody amount is about 31% (w/w of the dry formulation) or greater than about a 0.15:1 mass ratio of the amino acid to protein in the dry formulation. In still yet another embodiment, an amount of free amino acid in a dry (e.g., lyophilized) formulation can be in the range from about 4% to about 20% (w/w of dry formulation), or from about 10% to about 15% (w/w).

A surfactant concentration, e.g., in a pre-drying, (e.g., before lyophilization) or post-reconstitution formulation, can be, e.g., from about 0.0001% to about 1.0%, from about 0.01% to about 0.1%, for example about 0.02%, about 0.03%, about 0.04%, about 0.05%, about 0.06%, about 0.07%, about 0.08,%, about 0.09% (w/v), about 0.05% to about 0.07%, or about 0.06% (w/v). A surfactant amount, e.g., in a dry (e.g., lyophilized) formulation, can generally be from about 0.01% to about 3.0% (w/w), from about 0.10% to about 1.0%, for example about 0.15%, about 0.20%, about 0.25%, about 0.30%, about 0.35%, about 0.40%, or about 0.50% (w/w). In some embodiments, the surfactant is polysorbate 80.

Methods of Making Solid Formulations
Freeze-drying is a commonly employed technique for preserving proteins; freeze-drying serves to remove water from the protein preparation of interest. Freeze-drying, or lyophilization, is a process by which the material to be dried is first frozen and then the ice or frozen solvent is removed by sublimation under vacuum. Excipients can be included in the pre-lyophilized formulation to stabilize proteins during the lyophilization process and/or to improve the stability of the lyophilized protein formulation (Pikal M., Biopharm. 3(9)26-30 (1990) and Arakawa et al., Pharm. Res. 8(3):285-291 (1991)).
Amorphous proteins can be obtained by any suitable means, including freeze drying, spray-drying, spray-freeze drying, or precipitation, for example, from supercritical fluids. The foregoing processes, being relatively mild, advantageously provide the biologic protein in stable form with retention of the therapeutic activity.
Reconstitution of Solid Formulations
In some embodiments, a solid formulation can be dissolved (e.g., reconstituted) in a suitable medium or solvent to become a liquid formulation as described herein, suitable for administration to a patient by any suitable route, including incorporation into a device as disclosed herein. Suitable examples of solvents for reconstituting the solid formulation include water, isotonic saline, buffer, e.g., phosphate-buffered saline, citrate-buffered saline, Ringer's (lactated or dextrose) solution, minimal essential medium, alcohol/aqueous solutions, dextrose solution, etc. The amount of solvent can result in an antibody concentration higher, the same, or lower than the concentration of the antibody in the composition prior to drying.
In some embodiments, a liquid formulation is lyophilized and stored as a single dose in a container which may contain at least about 120 mg, about 180 mg, about 240 mg, about 300 mg, about 360 mg, about 540 mg, or about 900 mg of an antibody. The final dosage form, e.g., after dilution of the reconstituted antibody (e.g., in a saline or 5% dextrose), concentration of the antibody can be from about 0.5 mg/mL to about 500 mg/mL, for example, about 50 mg/mL, about 100 mg/mL, about 110 mg/mL, about 125 mg/mL, about 150 mg/mL, about 175 mg/mL, about 200 mg/mL, or greater.
Controlled-Release Formulations and Formulations with Encapsulated Therapeutic Proteins
An antibody or another therapeutic protein may be prepared with a carrier that will protect it against rapid release, such as in a controlled-release formulation, including microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used in these formulations, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Many methods for preparing such formulations are known to skilled practitioners. See, e.g., Sustained and Controlled Release Drug Delivery Systems, J. R. Robinson, ed., Marcel Dekker, Inc., New York, 1978.
In some embodiments, when antibody is crystalline, the protein crystals in the formulation can be embedded in, or encapsulated by, an excipient. Suitable examples of such excipients include any one or more of the polymers described herein. In some embodiments, crystals can then be embedded by drying the crystals and combining these dried crystals with a carrier, e.g., by compression, melt dispersion, etc. In some embodiments, crystals may be encapsulated/embedded by combining a crystal suspension with a carrier solution that is not miscible with water. The carrier precipitates after removal of the solvent of the carrier. Subsequently, the material is dried. In some embodiments, antibody crystals are encapsulated/embedded by combining a crystal suspension with a water miscible carrier solution. The carrier precipitates as its solubility limit is exceeded in the mixture. In some embodiments, antibody crystals are embedded by combining dried crystals or a crystal suspension with a water miscible carrier solution.
Antibody crystals may be encapsulated within a polymeric carrier to form coated particles. The coated particles of an antibody crystal formulation may have a spherical morphology and be microspheres of up to 500 micrometers in diameter or they may have some other morphology and be microparticulates. Formulations and methods of preparing the formulations comprising antibody crystals are described in WO 02/072636, which is incorporated by reference herein.
Also useful are formulations comprising an antibody or other therapeutic protein, and a controlled release matrix comprising at least one lipid or lipophilic vehicle; at least one hydrophilic polymer; at least one hygroscopic polymer; and at least one non-ionic surfactant. In one example, the matrix dissolves in the colon. Suitable examples of liquid lipid or lipophilic vehicle include, e.g., olive oil, sunflower oil, canola oil, palmitoleic acid, oleic acid, myristoleic acid, linoleic acid, arachidonic acid, paraffin oil, and mineral oil. Suitable examples of hygroscopic polymers include, e.g., polyvinylpyrrolidone, copovidone, hydroxypropylmethylcellulose, hydroxypropylcellulose, ethyl cellulose, methylcellulose, and polyethylene oxide. Suitable examples of non-ionic surfactants include, e.g., pluronic, lutrol, tween 80, span 80, egetal, and triton X-100. Additional examples of extended release matrixes are provided, for example, in US 2016/0287525, which is incorporated herein by reference in its entirety.
A formulation may comprise a semi-crystalline matrix, and an antibody or other therapeutic protein in microparticulate or nanoparticulate form entrapped in the matrix. In some embodiments, the matrix can comprise at least one semi-crystalline water soluble polymer in an amount of at least 50% by weight of the total mass of the matrix. In one example, the matrix is characterized by a melting point of at least about 40° C. and is water soluble. Suitable examples of semi-crystalline water soluble polymers include, e.g., polyalkylene glycols, polyalkylene glycol copolymers, polyvinyl alcohols, hydroxyalkyl celluloses, polysorbates, polyoxyethylene stearates, carrageenans, and alginates, and mixtures thereof. Other examples of such formulations are described in US 2017/0273909, which is incorporated by reference in its entirety.

In one example, a liquid formulation comprises adalimumab in combination with mannitol, citric acid monohydrate, sodium citrate, disodium phosphate dihydrate, sodium dihydrogen phosphate dihydrate, sodium chloride, polysorbate 80, water, and sodium hydroxide. The buffer can have a pH ranging from about 4 to about 8, from about 5 to about 8, from about 5 to about 7.5, from about 5 to about 7, from about 4.5 to about 6.0, from about 4.7 to about 5.7, from about 4.8 to about 5.5, or from about 5.0 to about 5.2. Suitable examples of buffers that can control the pH within the above ranges include acetate (e.g., sodium acetate), succinate (e.g., sodium succinate), gluconate, histidine, citrate and other organic acid buffers.
In some embodiments, a liquid formulation is buffered with histidine (and optionally arginine) amino acids and an acetate, while minimizing sodium chloride, with the buffers enhancing the thermal and colloidal stability of the antibody, even more so than formulations of adalimumab currently approved for patient use (e.g., currently approved injectable solutions). In some embodiments, the formulation contains a fine balance of an acidic pH of about 5.2 with the appropriate salts and buffer components. High levels of salt can induce aggregation and degradation, which could be improved by lowering the salt level. Accordingly, the present disclosure provides a buffered formulation of adalimumab comprising an aqueous carrier comprising buffer comprising histidine (and optionally arginine) amino acids and an acetate, and comprising mannitol, a non-ionic surfactant, and a minimal amount of sodium chloride.
In some embodiments, a formulation of adalimumab comprises a buffer system that contains citrate and phosphate to maintain the pH in a range of about 4 to about 8, from about 4.5 to about 6.0, from about 4.8 to about 5.5, or from about 5.0 to about 5.2. In one example, the buffer system includes citric acid monohydrate, sodium citrate, disodium phosphate dihydrate, and/or sodium dihydrogen phosphate dihydrate. In another example, the buffer system includes about 1.3 mg/mL of citric acid (e.g., 1.305 mg/mL), about 0.3 mg/mL of sodium citrate (e.g., 0.305 mg/mL), about 1.5 mg/mL of disodium phosphate dihydrate (e.g., 1.53 mg/mL), about 0.9 mg/mL of sodium dihydrogen phosphate dihydrate (e.g., 0.86), and about 6.2 mg/mL of sodium chloride (e.g., 6.165 mg/mL). In additional examples, the buffer system includes about 1-1.5 mg/mL of citric acid, about 0.25 mg/mL to about 0.5 mg/mL of sodium citrate, about 1.25 mg/mL to about 1.75 mg/mL of disodium phosphate dihydrate, about 0.7 mg/mL to about 1.1 mg/mL of sodium dihydrogen phosphate dihydrate, and about 6.0 mg/mL to about 6.4 mg/mL of sodium chloride. The pH of a formulation can be adjusted with an appropriate amount of sodium hydroxide.
In some embodiments, a liquid pharmaceutical formulation of adalimumab comprises about 1.3 mg/mL of citric acid, about 0.3 mg/mL of sodium citrate, about 1.5 mg/mL of disodium phosphate dihydrate, about 0.9 mg/mL of sodium dihydrogen phosphate dihydrate, and about 6.2 mg/mL of sodium chloride. In other embodiments, a liquid aqueous pharmaceutical formulation of adalimumab comprises about 1.305 mg/mL of citric acid, about 0.305 mg/mL of sodium citrate, about 1.53 mg/mL of disodium phosphate dihydrate, about 0.86 mg/mL of sodium dihydrogen phosphate dihydrate, and about 6.165 mg/mL of sodium chloride.
Polyols in Solid and Liquid Formulations of Adalimumab
A polyol, which acts as a tonicifier and can stabilize adalimumab, can be included in a formulation of adalimumab. The polyol can be added to the formulation in an amount that can vary with respect to the desired isotonicity of the formulation. In some embodiments, the aqueous formulation is isotonic. The amount of polyol added can also vary with respect to the molecular weight of the polyol. For example, a lower amount of a monosaccharide (e.g., mannitol) can be added, compared to a disaccharide (such as trehalose). In some embodiments, the polyol used in the formulation as a tonicity agent is mannitol. For example, the mannitol concentration can be about 5-20 mg/mL, about 7.5-15 mg/mL, about 10-14 mg/mL, or about 12 mg/mL. In some embodiments, the polyol sorbitol is included in the formulation.
Surfactants in Solid and Liquid Formulations of Adalimumab
A detergent or surfactant can be added to a formulation of adalimumab. Exemplary detergents include nonionic surfactants such as polysorbates (e.g., polysorbates 20, 80, etc.) or poloxamers (e.g., poloxamer 188 or 407). The amount of detergent added can be such that it reduces aggregation of adalimumab, minimizes the formation of particulates in the formulation and reduces adsorption. In some embodiments, the formulation includes a surfactant which is a polysorbate such as polysorbate 80 or Tween 80. Tween 80 is a term used to describe polyoxyethylene (20) sorbitanmonooleate (see Fiedler, Lexikon der Hifsstoffe, Editio Cantor Verlag Aulendorf, 4th edi., 1996). In some embodiments, the formulation is liquid and contains from about 0.1 mg/mL to about 10 mg/mL, from about 0.5 mg/mL to about 5 mg/mL, about 0.1%, or about 0.2% of polysorbate 80. In some embodiments, the formulation of adalimumab contains about 0.1-2 mg/mL, about 0.1-1.5 mg/mL, about 0.2-1.4 mg/mL, about 0.3-1.3 mg/mL, about 0.4-1.2 mg/mL, about 0.5-1.1 mg/mL, about 0.6-1.0 mg/mL, about 0.6-1.1 mg/mL, about 0.7-1.1 mg/mL, about 0.8-1.1 mg/mL, or about 0.9-1.1 mg/mL of a surfactant such as polysorbate 80.

In some embodiments, the pre-lyophilization vedolizumab formulation volume is the same as the pre-administration reconstituted solution volume. For example, a formulation that is about 5.5 mL pre-lyophilization can be reconstituted to a volume of about 5.5 mL, by adding an amount of liquid, e.g., water or saline, that takes into account the volume of the dry solids. In other embodiments, it is desirable to lyophilize the formulation in a different volume than the reconstituted solution volume. For example, the vedolizumab formulation can be lyophilized as a dilute solution, e.g., 0.25×, 0.5×, or 0.75× and reconstituted to 1× by adding less liquid, e.g., about 75% less, about half, or about 25% less than the pre-lyophilization volume. In some embodiments, a 300 mg dose of vedolizumab is lyophilized as a 30 mg/mL antibody solution in 5% sucrose and reconstituted to a 60 mg/mL antibody solution in 10% sucrose. Alternatively, a lyophilized vedolizumab formulation can be reconstituted into a more dilute solution than the pre-lyophilized formulation.

The effect of the topical delivery or topical administration of the medicament may be local to, or away from, the site of the topical administration. “Topical delivery,” “topical administration,” “topical application” and “topical treatment” are used interchangeably herein.
“Gastrointestinal inflammatory disorders” are a group of chronic disorders that cause inflammation and/or ulceration in the mucous membrane. These disorders include, for example, inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis, indeterminate colitis and infectious colitis), mucositis (e.g., oral mucositis, gastrointestinal mucositis, nasal mucositis and proctitis), necrotizing enterocolitis and esophagitis.
“Inflammatory Bowel Disease” or “IBD” is a chronic inflammatory autoimmune condition of the gastrointestinal (GI) tract. The GI tract can be divided into four main different sections, the oesophagus, stomach, small intestine and large intestine or colon. The small intestine possesses three main subcompartments: the duodenum, jejunum and ileum. Similarly, the large intestine consists of six sections: the cecum, ascending colon, transverse colon, ascending colon, sigmoid colon, and the rectum. The small intestine is about 6 m long, its diameter is about 2.5 to about 3 cm and the transit time through it is typically about 3 hours. The duodenum has a C-shape, and is about 30 cm long. Due to its direct connection with the stomach, it is physically more stable than the jejunum and ileum, which are sections that can freely move. The jejunum is about 2.4 m in length and the ileum is about 3.6 m in length and their surface areas are about 180 m2 and about 280 m2, respectively. The large intestine is about 1.5 m long, its diameter is between about 6.3 and about 6.5 cm, the transit time though this section is about 20 hours and has a reduced surface area of about 150 m2. The higher surface area of the small intestine enhances its capacity for systemic drug absorption.
The etiology of IBD is complex, and many aspects of the pathogenesis remain unclear. The treatment of moderate to severe IBD poses significant challenges to treating physicians, because conventional therapy with corticosteroids and immunomodulator therapy (e.g., azathioprine, 6-mercaptopurine, and methotrexate administered via traditional routes such as tablet form, oral suspension, or intravenously) is associated with side effects and intolerance and has not shown proven benefit in maintenance therapy (steroids). Monoclonal antibodies targeting tumor necrosis factor alpha (TNF-a), such as infliximab (a chimeric antibody) and adalimumab (a fully human antibody), are currently used in the management of CD. Infliximab has also shown efficacy and has been approved for use in UC. However, approximately 10%-20% of patients with CD are primary nonresponders to anti-TNF therapy, and another ˜20%-30% of CD patients lose response over time (Schnitzler et al., Gut 58:492-500 (2009)). Other adverse events (AEs) associated with anti-TNFs include elevated rates of bacterial infection, including tuberculosis, and, more rarely, lymphoma and demyelination (Chang et al., Nat Clin Pract Gastroenterol Hepatology 3:220 (2006); Hoentjen et al., World J. Gastroenterol. 15(17):2067 (2009)). No currently available therapy achieves sustained remission in more than 20%-30% of IBD patients with chronic disease (Hanauer et al., Lancet 359: 1541-49 (2002); Sandborn et al., N Engl J Med 353: 1912-25 (2005)). In addition, most patients do not achieve sustained steroid-free remission and mucosal healing, clinical outcomes that correlate with true disease modification.
Although the cause of IBD remains unknown, several factors such as genetic, infectious and immunologic susceptibility have been implicated. IBD is much more common in Caucasians, especially those of Jewish descent. The chronic inflammatory nature of the condition has prompted an intense search for a possible infectious cause. Although agents have been found which stimulate acute inflammation, none has been found to cause the chronic inflammation associated with IBD. The hypothesis that IBD is an autoimmune disease is supported by the previously mentioned extraintestinal manifestation of IBD as joint arthritis, and the known positive response to IBD by treatment with therapeutic agents such as adrenal glucocorticoids, cyclosporin A and azathioprine, which are known to suppress immune response. In addition, the GI tract, more than any other organ of the body, is continuously exposed to potential antigenic substances such as proteins from food, bacterial byproducts (LPS), etc.
A chronic inflammatory autoimmune condition of the gastrointestinal (GI) tract presents clinically as either ulcerative colitis (UC) or Crohn's disease (CD). Both IBD conditions are associated with an increased risk for malignancy of the GI tract.
“Crohn's disease” (“CD”) is a chronic transmural inflammatory disease with the potential to affect any part of the entire GI tract, and UC is a mucosal inflammation of the colon. Both conditions are characterized clinically by frequent bowel motions, malnutrition, and dehydration, with disruption in the activities of daily living.
CD is frequently complicated by the development of malabsorption, strictures, and fistulae and may require repeated surgery. UC, less frequently, may be complicated by severe bloody diarrhea and toxic megacolon, also requiring surgery. The most prominent feature Crohn's disease is the granular, reddish-purple edematous thickening of the bowel wall. With the development of inflammation, these granulomas often lose their circumscribed borders and integrate with the surrounding tissue. Diarrhea and obstruction of the bowel are the predominant clinical features. As with ulcerative colitis, the course of Crohn's disease may be continuous or relapsing, mild or severe, but unlike ulcerative colitis, Crohn's disease is not curable by resection of the involved segment of bowel. Most patients with Crohn's disease require surgery at some point, but subsequent relapse is common and continuous medical treatment is usual. Crohn's disease may involve any part of the alimentary tract from the mouth to the anus, although typically it appears in the ileocolic, small-intestinal or colonic-anorectal regions. Histopathologically, the disease manifests by discontinuous granulomatomas, crypt abscesses, fissures and aphthous ulcers. The inflammatory infiltrate is mixed, consisting of lymphocytes (both T and B cells), plasma cells, macrophages, and neutrophils. There is a disproportionate increase in IgM- and IgG-secreting plasma cells, macrophages and neutrophils.
To date, the primary outcome measure in Crohn's Disease clinical trials is the Crohn's Disease Activity Index (CDAI), which has served as the basis for approval of multiple drug treatments, including for example, vedolizumab and natalizumab. The CDAI was developed by regressing clinician global assessment of disease activity on eighteen potential items representing patient reported outcomes (PROs) (i.e., abdominal pain, pain awakening patient from sleep, appetite), physical signs (i.e., average daily temperature, abdominal mass), medication use (i.e., loperamide or opiate use for diarrhea) and a laboratory test (i.e., hematocrit). Backward stepwise regression analysis identified eight independent predictors which are the number of liquid or soft stools, severity of abdominal pain, general well-being, occurrence of extra-intestinal symptoms, need for anti-diarrheal drugs, presence of an abdominal mass, hematocrit, and body weight. The final score is a composite of these eight items, adjusted using regression coefficients and standardization to construct an overall CDAI score, ranging from 0 to 600 with higher score indicating greater disease activity. Widely used benchmarks are: CDAI <150 is defined as clinical remission, 150 to 219 is defined as mildly active disease, 220 to 450 is defined as moderately active disease, and above 450 is defined as very severe disease (Best W R, et al., Gastroenterology 77:843-6, 1979). Vedolizumab and natalizumab have been approved on the basis of demonstrated clinical remission, i.e., CDAI <150.
Although the CDAI has been in use for over 40 years, and has served as the basis for drug approval, it has several limitations as an outcome measure for clinical trials. For example, most of the overall score comes from the patient diary card items (pain, number of liquid bowel movements, and general well-being), which are vaguely defined and not standardized terms (Sandler et al., J. Clin. Epidemiol 41:451-8, 1988; Thia et al., Inflamm Bowel Dis 17:105-11, 2011). In addition, measurement of pain is based on a four-point scale rather than an updated seven-point scale. The remaining 5 index items contribute very little to identifying an efficacy signal and may be a source of measurement noise. Furthermore, concerns have been raised about poor criterion validity for the CDAI, a reported lack of correlation between the CDAI and endoscopic measures of inflammation (which may render the CDAI as a poor discriminator of active CD and irritable bowel syndrome) and high reported placebo rates (Korzenik et al., N Engl J Med. 352:2193-201, 2005; Sandborn W J, et al., N Engl J Med 353:1912-25, 2005; Sandborn W J, et al., Ann Intern 19; 146:829-38, 2007, Epub 2007 Apr. 30; Kim et al., Gastroenterology 146:(5 supplement 1) S-368, 2014).
It is, thus, generally recognized that additional or alternative measures of CD symptoms are needed, such as new PRO tools or adaptations of the CDAI to derive a new PRO. The PRO2 and PRO3 tools are such adaptations of the CDAI and have been recently described in Khanna et al., Aliment Pharmacol. Ther. 41:77-86, 2015. The PRO2 evaluates the frequency of loose/liquid stools and abdominal pain (Id). These items are derived and weighted accordingly from the CDAI and are the CDAI diary card items, along with general well-being, that contribute most to the observed clinical benefit measured by CDAI (Sandler et al., J. Clin. Epidemiol 41:451-8, 1988; Thia et al., Inflamm Bowel Dis 17:105-11, 2011; Kim et al., Gastroenterology 146:(5 supplement 1) S-368, 2014). The remission score of <11 is the CDAI-weighted sum of the average stool frequency and pain scores in a 7-day period, which yielded optimum sensitivity and specificity for identification of CDAI remission (score of <150) in a retrospective data analysis of ustekinumab induction treatment for moderate to severe CD in a Phase II clinical study (Gasink C, et al., abstract, ACG Annual Meeting 2014). The PRO2 was shown to be sensitive and responsive when used as a continuous outcome measure in a retrospective data analysis of MTX treatment in active CD (Khanna R, et al., Inflamm Bowel Dis 20:1850-61, 2014) measured by CDAI. Additional outcome measures include the Mayo Clinic Score, the Crohn disease endoscopic index of severity (CDEIS), and the Ulcerative colitis endoscopic index of severity (UCEIS). Additional outcome measures include Clinical remission, Mucosal healing, Histological healing (transmural), MRI or ultrasound for measurement or evaluation of bowel wall thickness, abscesses, fistula and histology.
An additional means of assessing the extent and severity of Crohn's Disease is endoscopy. Endoscopic lesions typical of Crohn's disease have been described in numerous studies and include, e.g., aphthoid ulcerations, “punched-out ulcers,” cobblestoning and stenosis. Endoscopic evaluation of such lesions was used to develop the first validated endoscopic score, the Crohn's Disease Endoscopic Index of Severity (CDEIS) (Mary et al., Gut 39:983-9, 1989). More recently, because the CDEIS is time-consuming, complicated and impractical for routine use, a Simplified Endoscopic Activity Score for Crohn's Disease (SES-CD) was developed and validated (Daperno et al., Gastrointest. Endosc. 60(4):505-12, 2004). The SES-CD consists of four endoscopic variables (size of ulcers, proportion of surface covered by ulcers, proportion of surface with any other lesions (e.g., inflammation), and presence of narrowings [stenosis]) that are scored in five ileocolonic segments, with each variable, or assessment, rated from 0 to 3.
To date, there is no cure for CD. Accordingly, the current treatment goals for CD are to induce and maintain symptom improvement, induce mucosal healing, avoid surgery, and improve quality of life (Lichtenstein G R, et al., Am J Gastroenterol 104:465-83, 2009; Van Assche G, et al., J Crohns Colitis. 4:63-101, 2010). The current therapy of IBD usually involves the administration of antiinflammatory or immunosuppressive agents, such as sulfasalazine, corticosteroids, 6-mercaptopurine/azathioprine, or cyclosporin A, all of which are not typically delivered by localized release of a drug at the site or location of disease. More recently, biologics like TNF-alpha inhibitors and IL-12/IL-23 blockers, are used to treat IBD. If anti-inflammatory/immunosuppressive/biologic therapies fail, colectomies are the last line of defense. The typical operation for CD not involving the rectum is resection (removal of a diseased segment of bowel) and anastomosis (reconnection) without an ostomy. Sections of the small or large intestine may be removed. About 30% of CD patients will need surgery within the first year after diagnosis. In the subsequent years, the rate is about 5% per year. Unfortunately, CD is characterized by a high rate of recurrence; about 5% of patients need a second surgery each year after initial surgery.
Refining a diagnosis of inflammatory bowel disease involves evaluating the progression status of the diseases using standard classification criteria. The classification systems used in IBD include the Truelove and Witts Index (Truelove S. C. and Witts, L. J. Br Med J. 1955; 2:1041-1048), which classifies colitis as mild, moderate, or severe, as well as Lennard-Jones. (Lennard-Jones J E. Scand J Gastroenterol Suppl 1989; 170:2-6) and the simple clinical colitis activity index (SCCAI). (Walmsley et. al. Gut. 1998; 43:29-32) These systems track such variables as daily bowel movements, rectal bleeding, temperature, heart rate, hemoglobin levels, erythrocyte sedimentation rate, weight, hematocrit score, and the level of serum albumin.
There is sufficient overlap in the diagnostic criteria for UC and CD that it is sometimes impossible to say which a given patient has; however, the type of lesion typically seen is different, as is the localization. UC mostly appears in the colon, proximal to the rectum, and the characteristic lesion is a superficial ulcer of the mucosa; CD can appear anywhere in the bowel, with occasional involvement of stomach, esophagus and duodenum, and the lesions are usually described as extensive linear fissures.
In approximately 10-15% of cases, a definitive diagnosis of ulcerative colitis or Crohn's disease cannot be made and such cases are often referred to as “indeterminate colitis.” Two antibody detection tests are available that can help the diagnosis, each of which assays for antibodies in the blood. The antibodies are “perinuclear anti-neutrophil antibody” (pANCA) and “anti-Saccharomyces cerevisiae antibody” (ASCA). Most patients with ulcerative colitis have the pANCA antibody but not the ASCA antibody, while most patients with Crohn's disease have the ASCA antibody but not the pANCA antibody. However, these two tests have shortcomings as some patients have neither antibody and some Crohn's disease patients may have only the pANCA antibody. A third test, which measures the presence and accumulation of circulating anti-microbial antibodies—particularly flagellin antibodies, has proven to be useful for detecting susceptibility to Crohn's Disease before disease development. See Choung, R. S., et al., “Serologic microbial associated markers can predict Crohn's disease behaviour years before disease diagnosis,” Alimentary Pharmacology and Therapeutics 43.12 (2016):1300-1310.
“Ulcerative colitis (UC)” afflicts the large intestine. The course of the disease may be continuous or relapsing, mild or severe. The earliest lesion is an inflammatory infiltration with abscess formation at the base of the crypts of Lieberkuhn. Coalescence of these distended and ruptured crypts tends to separate the overlying mucosa from its blood supply, leading to ulceration. Symptoms of the disease include cramping, lower abdominal pain, rectal bleeding, and frequent, loose discharges consisting mainly of blood, pus and mucus with scanty fecal particles. A total colectomy may be required for acute, severe or chronic, unremitting ulcerative colitis.
The clinical features of UC are highly variable, and the onset may be insidious or abrupt, and may include diarrhea, tenesmus and relapsing rectal bleeding. With fulminant involvement of the entire colon, toxic megacolon, a life-threatening emergency, may occur. Extraintestinal manifestations include arthritis, pyoderma gangrenoum, uveitis, and erythema nodosum.
An “antibody” is an immunoglobulin molecule capable of specific binding to a target, such as a carbohydrate, polynucleotide, lipid, polypeptide, etc., through at least one antigen recognition site, located in the variable region of the immunoglobulin molecule. The terms “antibody” and “immunoglobulin” are used interchangeably in the broadest sense. As used herein, the terms encompass monoclonal antibodies (for example, full length or intact monoclonal antibodies), polyclonal antibodies (for example, full length or intact polyclonal antibodies), and fragments thereof (such as Fab, Fab′, F(ab′)2, Fv), single chain (ScFv) and domain antibodies), fusion proteins including an antibody portion, multivalent antibodies, multispecific antibodies (e.g., bispecific, trispecific, etc. antibodies so long as they exhibit the desired biological activity), and any other modified configuration of the immunoglobulin molecule that includes an antigen recognition site. An antibody can be human, humanized and/or affinity matured.
The term antibody includes antibody fragments (e.g., antigen-binding fragments) such as an Fv fragment, a Fab fragment, a F(ab′)2 fragment, and a Fab′ fragment. “Antibody fragments” comprise only a portion of an intact antibody, where in certain embodiments, the portion retains at least one, and typically most or all, of the functions normally associated with that portion when present in an intact antibody. In one embodiment, an antibody fragment comprises an antigen binding site of the intact antibody and thus retains the ability to bind antigen. In another embodiment, an antibody fragment, for example one that comprises the Fc region, retains at least one of the biological functions normally associated with the Fc region when present in an intact antibody, such as FcRn binding, antibody half-life modulation, ADCC function and complement binding. In one embodiment, an antibody fragment is a monovalent antibody that has an in vivo half-life substantially similar to an intact antibody. For example, such an antibody fragment may comprise on antigen binding arm linked to an Fc sequence capable of conferring in vivo stability to the fragment. Additional examples of antigen-binding fragments include an antigen-binding fragment of an IgG (e.g., an antigen-binding fragment of IgG1, IgG2, IgG3, or IgG4) (e.g., an antigen-binding fragment of a human or humanized IgG, e.g., human or humanized IgG1, IgG2, IgG3, or IgG4); an antigen-binding fragment of an IgA (e.g., an antigen-binding fragment of IgA1 or IgA2) (e.g., an antigen-binding fragment of a human or humanized IgA, e.g., a human or humanized IgA1 or IgA2); an antigen-binding fragment of an IgD (e.g., an antigen-binding fragment of a human or humanized IgD); an antigen-binding fragment of an IgE (e.g., an antigen-binding fragment of a human or humanized IgE); or an antigen-binding fragment of an IgM (e.g., an antigen-binding fragment of a human or humanized IgM). An antibody includes an antibody of any class, such as IgG, IgA, or IgM (or sub-class thereof), and the antibody need not be of any particular class. Depending on the antibody amino acid sequence of the constant domain of its heavy chains, immunoglobulins can be assigned to different classes. There are five major classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM, and several of these may be further divided into subclasses (isotypes), e.g., IgG1, IgG2, IgG3, IgG4, IgA1 and IgA2. The heavy-chain constant domains that correspond to the different classes of immunoglobulins are called alpha, delta, epsilon, gamma, and mu, respectively. The subunit structures and three-dimensional configurations of different classes of immunoglobulins are well known.
The term “monoclonal antibody” as used herein refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. Monoclonal antibodies are highly specific, being directed against a single antigen or antigenic site. Furthermore, in contrast to polyclonal antibody preparations that typically include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. The modifier “monoclonal” indicates the character of the antibody as being obtained from a substantially homogeneous population of antibodies, and is not to be construed as requiring production of the antibody by any particular method. For example, the monoclonal antibodies to be used in accordance with the present disclosure may be made by the hybridoma method first described by Kohler and Milstein, 1975, Nature 256:495, or may be made by recombinant DNA methods such as described in U.S. Pat. No. 4,816,567. The monoclonal antibodies may also be isolated from phage libraries generated using the techniques described in McCafferty et al., 1990, Nature 348:552-554, for example.
The monoclonal antibodies herein specifically include “chimeric” antibodies in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, so long as they exhibit the desired biological activity (U.S. Pat. No. 4,816,567; and Morrison et al., Proc. Natl. Acad. Sci. USA 81:6851-6855 (1984)).
A “variable region” of an antibody refers to the variable region of the antibody light chain or the variable region of the antibody heavy chain, either alone or in combination. As known in the art, the variable regions of the heavy and light chain each consist of four framework regions (FR) connected by three complementarity determining regions (CDRs) that contain hypervariable regions. The CDRs in each chain are held together in close proximity by the FRs and, with the CDRs from the other chain, contribute to the formation of the antigen-binding site of antibodies. There are at least two techniques for determining CDRs: (1) an approach based on cross-species sequence variability (i.e., Kabat et al., Sequences of Proteins of Immunological Interest, (5th ed., 1991, National Institutes of Health, Bethesda Md.)); and (2) an approach based on crystallographic studies of antigen-antibody complexes (Al-Lazikani et al., 1997, J. Molec. Biol. 273:927-948). As used herein, a CDR may refer to CDRs defined by either approach or by a combination of both approaches.
As known in the art, a “constant region” of an antibody refers to the constant region of the antibody light chain or the constant region of the antibody heavy chain, either alone or in combination.
As used herein, “TNF” is interchangeable with the terms “TNF-alpha” and “TNF-α” and the term “TNF inhibitor,” as used herein, is interchangeable with the term “anti-TNF agent.”
“Treatment regimen” refers to a combination of dosage, frequency of administration, or duration of treatment, with or without addition of a second medication.
“Effective treatment regimen” refers to a treatment regimen that will offer beneficial response to a patient receiving the treatment.
“Effective amount” refers to an amount of drug that offers beneficial response to a patient receiving the treatment. For example, an effective amount may be a Human Equivalent Dose (HED).
“Dispensable,” with reference to any substance, refers to any substance that may be released from an ingestible device as disclosed herein, or from a component of the device such as a reservoir. For example, a dispensable substance may be an IL-12/IL-23 inhibitor, and/or a formulation comprising an IL-12/IL-23 inhibitor.
“Patient response” or “patient responsiveness” can be assessed using any endpoint indicating a benefit to the patient, including, without limitation, (1) inhibition, to some extent, of disease progression, including slowing down and complete arrest; (2) reduction in the number of disease episodes and/or symptoms; (3) reduction in lesional size; (4) inhibition (i.e., reduction, slowing down or complete stopping) of disease cell infiltration into adjacent peripheral organs and/or tissues; (5) inhibition (i.e., reduction, slowing down or complete stopping) of disease spread; (6) decrease of auto-immune response, which may, but does not have to, result in the regression or ablation of the disease lesion; (7) relief, to some extent, of one or more symptoms associated with the disorder; (8) increase in the length of disease-free presentation following treatment; and/or (9) decreased mortality at a given point of time following treatment. The term “responsiveness” refers to a measurable response, including complete response (CR) and partial response (PR).
As used herein, “complete response” or “CR” means the disappearance of all signs of inflammation or remission in response to treatment. This does not necessarily mean the disease has been cured.
“Partial response” or “PR” refers to a decrease of at least 50% in the severity of inflammation, in response to treatment.
A “beneficial response” of a patient to treatment with a therapeutic agent and similar wording refers to the clinical or therapeutic benefit imparted to a patient at risk for or suffering from a gastrointestinal inflammatory disorder from or as a result of the treatment with the agent. Such benefit includes cellular or biological responses, a complete response, a partial response, a stable disease (without progression or relapse), or a response with a later relapse of the patient from or as a result of the treatment with the agent.
As used herein, “non-response” or “lack of response” or similar wording means an absence of a complete response, a partial response, or a beneficial response to treatment with a therapeutic agent.
“A patient maintains responsiveness to a treatment” when the patient's responsiveness does not decrease with time during the course of a treatment.
A “symptom” of a disease or disorder (e.g., inflammatory bowel disease, e.g., ulcerative colitis or Crohn's disease) is any morbid phenomenon or departure from the normal in structure, function, or sensation, experienced by a subject and indicative of disease.
As used herein, “accuracy,” when disclosed in connection with a specified location of a device within the GI tract of a subject, refers to the degree to which the location determined by the device conforms to the correct location, wherein the correct location is based on a generally accepted standard. The location within the GI tract of the subject determined by the device can be based on data, for example, light reflectance data, collected by the ingestible device. In some embodiments, the correct location can be based on external imaging devices, such as computer-aided tomography (CT), interpreted, for example, by a qualified clinician or physician. Therefore, percent accuracy (“% accuracy”) can refer to the percentage agreement between the location of the device in the GI tract as determined by the device, and the correct location, for example, as determined by CT, e.g., expressed as [(number of devices in which location determined by the device agrees with location as determined by CT/total devices administered to the subject or subjects)×100%], or, where only one device is administered per subject, [(number of subjects in which location determined by the device agrees with location as determined by CT/total number of subjects)×100%]. The latter formula for determining % accuracy was used in Example 14. In some embodiments, the accuracy with which the device determines a location refers to the accuracy with which the device determines that it is at a location pre-selected for drug release.
As used herein, an “autonomous device” refers to a device comprising one or more processors configured to independently control certain mechanisms or operations of the device while in the GI tract of a subject. Preferably, an autonomous device of the present disclosure has no external electrical or wireless connections that control device mechanisms or operations, although connections such as wireless connections may be present to enable alternative device functions, such as transmitting data collected by the device to an external (ex vivo) system or receiver. The independently controlled mechanisms or operations of the autonomous device include, for example, triggering the release of a drug (or the formulation comprising the drug), triggering collection of one or more samples, and/or triggering the analysis of one or more samples; and/or determining the location of the device within the GI tract of the subject. Such mechanisms are referred to herein as “autonomous mechanisms,” or, for example, an “autonomous triggering mechanism” or an “autonomous localization mechanism,” respectively. Actively implementing such an autonomous triggering or autonomous localization mechanism is referred to as “autonomous triggering” or “autonomous localizing,” respectively. An “autonomous localization mechanism” is synonymous with a “self-localization mechanism.”
As used herein, a “housing” is a portion of an ingestible device that defines the boundary between the interior of the device and the environment exterior to the device.
As used herein, a “self-localizing device” refers to a device comprising a mechanism or system that can be implemented autonomously to determine the location of the ingestible device in vivo, e.g., within the GI tract of a subject. Such a mechanism is referred to as a “self-localization mechanism.” A “self-localization mechanism” is synonymous with an “autonomous localization mechanism.” A self-localizing device does not require ex vivo visualization devices or systems, for example, using scintigraphy or computer-aided tomography (CT), to localize in the GI tract.
As used herein, “localizing a device” refers to determining a location of the device.
As used herein, “self-localizing a device” refers to determining a location of the device via a device self-localization mechanism, e.g., determining a location of the within the GI tract of a subject via a device self-localization mechanism.
As used herein, “sensor” refers to a mechanism or portion of a mechanism configured to collect information regarding the surroundings of the ingestible device. Examples of “sensors” include environmental sensors and light sensors. Examples of environmental sensors include pH sensors and sensors capable to identifying muscle contractions and/or peristalsis.
As used herein, “time of transition” of the device refers to elapsed time during passage of the device from one portion of the GI tract into a second portion of the GI tract. In some embodiments, the second portion of the GI tract is adjacent to the first portion. Non-limiting examples of time of transition include the elapsed time during passage of the device between mouth and stomach, esophagus and stomach, stomach and duodenum, duodenum and jejunum, jejunum and ileum, ileum and cecum, or cecum and colon.
As used herein, “time following transition” of the device refers to elapsed time after passage of the device from one portion of the GI tract into a second portion of the GI tract. In some embodiments, the second portion of the GI tract is adjacent to the first portion. Non-limiting examples of time following transition include elapsed time following passage of the device between mouth and stomach, esophagus and stomach, stomach and duodenum, duodenum and jejunum, jejunum and ileum, ileum and cecum, or cecum and colon.
As used herein, a “portion” of the GI tract refers to an anatomical section or subsection of the GI tract. Non-limiting examples of a portion of the GI tract include the mouth, the esophagus, the stomach, the duodenum, the jejunum, the ileum, the cecum, the colon, the ascending colon, the transverse colon, the descending colon, and the rectum.
As used herein, “proximate” as disclosed in connection with release of a drug from a device to one or more disease sites, refers to a location that is sufficiently spatially close to the one or more disease sites such that releasing the drug at the location treats the disease. For example, when the drug is released proximate to the one or more disease sites, the drug may be released 150 cm or less, such as 125 cm or less, such as 100 cm or less, such as 50 cm or less, such as 40 cm or less, such as 30 cm or less, such as 20 cm or less, such as 10 cm or less, such as 5 cm or less, such as 2 cm or less, from the one or more sites of disease. In some embodiments, the proximate location for drug release is the same section or subsection of the gastrointestinal tract containing the one or more disease site. Thus, where the present application refers to release of a drug proximate to a site of disease, this in some embodiments refers to release of the drug to a section or subsection of the GI tract that contains a site of disease. For example, when a disease site is in the ileum, the drug may be released proximate to the disease site by releasing the drug to the ileum. In some embodiments, the proximate location for drug release is a different section or subsection of the GI tract than that containing the disease site; for example, the drug release may be proximal to the disease site. Thus, where the present application refers to release of a drug proximate to a site of disease, this in some embodiments refers to release of the drug to a section or subsection of the GI tract that is proximal to the section or subsection containing the disease site. For example, when a disease site is in the ileum, the drug may be released to the jejunum.
As used herein, “proximal,” when used in connection with an anatomical structure, refers to a portion that precedes, or is upstream of, an adjacent portion of the anatomical structure. In some embodiments, proximal refers to a portion of an anatomical structure that immediately precedes, or is immediately upstream of, an immediately adjacent portion of the anatomical structure. “Proximal,” when used in connection with release of a drug from a device to one or more disease sites, refers to release of the drug from the device to a portion of an anatomical structure that precedes, or is upstream of, an adjacent portion of an anatomical structure that contains one or more disease sites. The portion may be a section of the GI tract, which may be selected from mouth, esophagus, stomach, duodenum, jejunum, ileum, cecum, ascending colon, transverse colon, descending colon, and rectum. The portion may be a subsection of the GI tract, which may be selected from proximal duodenum, proximal jejunum, proximal ileum, proximal cecum, proximal ascending colon, proximal transverse colon, proximal descending colon, distal duodenum, distal jejunum, distal ileum, distal cecum, distal ascending colon, distal transverse colon, distal descending colon. In some exemplary embodiments, the drug is released to the cecum (e.g., to a location proximal to the ascending colon) to treat a site of disease tissue in the ascending colon (i.e., a site of disease distal to the cecum). In another embodiment, the drug is released to the cecum (e.g., to a location proximal to the colon) to treat a site of disease tissue in one or more of the ascending colon, transverse colon, descending colon, or a combination thereof (e.g., a site of disease distal to the cecum).
As used herein, “distal,” when used in connection with an anatomical structure, refers to a portion, section, or subsection that follows, or is downstream of, an adjacent portion, section, or subsection of the anatomical structure. In some embodiments, distal refers to a portion, section, or subsection that immediately follows, or is immediately downstream of, an immediately adjacent portion, section, or subsection of the anatomical structure.
As used herein, the “total induction dose” is the sum of induction doses over a given time period.
As used herein, the term “adhesion” refers to the ability of the formulations of the present disclosure to bind to the site of topical administration, e.g., mucoses (e.g., a mucosal lining of the gastrointestinal tract of a subject), upon contact, whereby when they are brought into contact work must be done in order to separate them. The adhesion can be measured by a texture analyzer, e.g., TA.XT Plus (Texture Technologies). For example, a 40-mm diameter disk can be compressed into the gel and redrawn. The method settings, including speed rate at 1 mm/second and distance (depth of the insertion) of 9-mm can be assessed at the desired temperature, e.g., at 22° C., 25° C. or at 37° C. The adhesion is measured in mN/s units. The more negative the value in mN/s, the more adhesive the composition will be. Thus, for example a composition showing a measurement value of −100 mN/s is more adhesive than a composition showing a lower measurement value of e.g., −50 mN/s.
As used herein, the term “thermoreversible” or equivalent expressions thereof such as “thermally reversible” applied to the composition means that it exhibits reverse thermogellation, i.e., it undergoes a change in viscosity when the temperature varies. In some embodiments, the composition is liquid at room temperature and forms a gel at body temperature. The liquid state at room temperature facilitates the administration of the composition when it is to be administered, e.g., to the gastrointestinal mucosa, by using an appropriate delivery device, such as for example an ingestible device as disclosed herein. When the composition is released from the device and comes into contact with the mucosa at body temperature, its viscosity increases to a higher viscosity state, hence acquiring the consistency of a gel. This has the advantage that the composition remains on the surface of the affected area.
The terms “pharmaceutically acceptable carrier,” “pharmaceutically acceptable diluent” and “pharmaceutically acceptable excipient” include any and all solvents, co-solvents, complexing agents, dispersion media, coatings, isotonic and absorption delaying agents and the like which are not biologically or otherwise undesirable. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in the therapeutic formulations is contemplated. Supplementary active ingredients can also be incorporated into the formulations. In addition, various adjuvants such as are commonly used in the art may be included. These and other such therapeutic agents are described in the literature, e.g., in the Merck Index, Merck & Company, Rahway, N.J. Considerations for the inclusion of various components in pharmaceutical formulations are described, e.g., in Gilman et al. (Eds.) (2010); Goodman and Gilman's: The Pharmacological Basis of Therapeutics, 12th Ed., The McGraw-Hill Companies.
As used herein, the term “pharmaceutically acceptable salt” refers to those salts of compounds disclosed herein that are safe and effective for use in mammals, including humans, and that possess the desired biological activity. Pharmaceutically acceptable salts are known to the person of ordinary skill in the art. In a non-limiting example, when the compound has an acidic group such as carboxyl group in the formula, the salts can be salts thereof with alkali metals, e.g. sodium, potassium and ammonium, salts thereof with alkaline earth metals, e.g. calcium and magnesium, salts thereof with aluminum and zinc, salts thereof with organic amines, e.g. triethylamine, ethanolamine, morpholine, piperidine and dicyclohexylamine, and salts thereof with basic amino acids, e.g. arginine and lysine. In a non-limiting example, when the compound has a basic group in the formula, the salts can be those with inorganic acids, e.g., hydrochloric acid, sulfuric acid and phosphoric acid; those with organic carboxylic acids, e.g. acetic acid, citric acid, benzoic acid, maleic acid, fumaric acid, tartaric acid and succinic acid; and those with organosulfonic acids, e.g., methanesulfonic acid and p-toluenesulfonic acid. The salts can be formed by mixing a compound with a necessitated acid or base in a proper ratio in a solvent or dispersing agent or by the cation exchange or anion exchange reaction with another salt.
As used herein, a reference to a drug's international nonproprietary name (INN) is to be interpreted as including generic, bioequivalent and biosimilar versions of that drug, including but not limited to any drug that has received abbreviated regulatory approval by reference to an earlier regulatory approval of that drug. Additionally, all drugs disclosed herein optionally include the pharmaceutically acceptable salts and solvates of the drugs thereof, unless expressly indicated otherwise.
As used herein, each listed small molecule, peptide or nucleic acid agent optionally includes a pharmaceutically acceptable salt thereof, whether or not such a form is expressly indicated. Each listed antibody agent optionally includes a biosimilar thereof, whether or not such a biosimilar is expressly indicated.
Activity and/or Expression of IL-12/IL-23 Inhibitors
The term “IL-12/IL-23 inhibitor” refers to an agent which decreases the activity of IL-12 and/or IL-23, wherein the decrease in activity includes one or more of: (1) a decrease in the expression of IL-12 and/or IL-23, e.g., as compared to the level of IL-12 and/or IL-23 expression in the absence of the agent; (2) a decrease in the ability of IL-12 to bind to an IL-12 receptor or the ability of IL-23 to bind to an IL-23 receptor, e.g., as compared to the level of IL-12/IL-23 activity in the absence of the agent; and (3) a decrease in the level of an IL-12/IL-23 protein in a mammalian cell contacted with the agent, e.g., as compared to the same mammalian cell not contacted with the agent. IL-12 is a heterodimeric cytokine that includes both IL-12A (p35) and IL-12B (p40) polypeptides. IL-23 is a heterodimeric cytokine that includes both IL-23 (p19) and IL-12B (p40) polypeptides.

In some embodiments, an IL-12/IL-23 inhibitor can be a small molecule (e.g., an organic, an inorganic, or bioinorganic molecule) having a molecule weight of less than 900 Daltons (e.g., less than 500 Daltons). In some embodiments, an IL-12/IL-23 inhibitor can be an inhibitory nucleic acid.
In some embodiments, an IL-12/IL-23 inhibitor is an inhibitory nucleic acid. In some embodiments, the inhibitory nucleic acid is an antisense nucleic acid, a ribozyme, or a small interfering RNA (siRNA). Examples of aspects of these different oligonucleotides are described below. Any of the examples of inhibitory nucleic acids that can decrease expression of IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA in a mammalian cell can be synthesized in vitro.
Inhibitory nucleic acids that can decrease the expression of IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA expression in a mammalian cell include antisense nucleic acid molecules, i.e., nucleic acid molecules whose nucleotide sequence is complementary to all or part of an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA (e.g., complementary to all or a part of any one of SEQ ID NOs: 1-12).
An antisense nucleic acid molecule can be complementary to all or part of a non-coding region of the coding strand of a nucleotide sequence encoding an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein. Non-coding regions (5′ and 3′ untranslated regions) are the 5′ and 3′ sequences that flank the coding region in a gene and are not translated into amino acids.
Based upon the sequences disclosed herein, one of skill in the art can easily choose and synthesize any of a number of appropriate antisense nucleic acids to target a nucleic acid encoding an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein described herein. Antisense nucleic acids targeting a nucleic acid encoding an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein can be designed using the software available at the Integrated DNA Technologies website.
An antisense nucleic acid can be, for example, about 5, 10, 15, 20, 25, 30, 35, 40, 45, or 50 nucleotides or more in length. An antisense oligonucleotide can be constructed using chemical synthesis and enzymatic ligation reactions using procedures known in the art. For example, an antisense nucleic acid can be chemically synthesized using naturally occurring nucleotides or variously modified nucleotides designed to increase the biological stability of the molecules or to increase the physical stability of the duplex formed between the antisense and sense nucleic acids, e.g., phosphorothioate derivatives and acridine substituted nucleotides can be used.
Examples of modified nucleotides which can be used to generate an antisense nucleic acid include 5-fluorouracil, 5-bromouracil, 5-chlorouracil, 5-iodouracil, hypoxanthine, xanthine, 4-acetyl cytosine, 5-(carboxyhydroxylmethyl) uracil, 5-carboxymethylaminomethyl-2-thiouridine, 5-carboxymethylaminomethyluracil, dihydrouracil, beta-D-galactosylqueosine, inosine, N6-isopentenyladenine, 1-methylguanine, 1-methylinosine, 2,2-dimethylguanine, 2-methyladenine, 2-methylguanine, 3-methylcytosine, 5-methylcytosine, N6-adenine, 7-methylguanine, 5-methylaminomethyluracil, 5-methoxyaminomethyl-2-thiouracil, beta-D-mannosylqueosine, 5′-methoxycarboxymethyluracil, 5-methoxyuracil, 2-methylthio-N6-isopentenyladenine, uracil-5-oxyacetic acid (v), wybutoxosine, pseudouracil, queosine, 2-thiocytosine, 5-methyl-2-thiouracil, 2-thiouracil, 4-thiouracil, 5-methyluracil, uracil-5-oxyacetic acid methylester, uracil-5-oxyacetic acid (v), 5-methyl-2-thiouracil, 3-(3-amino-3-N-2-carboxypropyl) uracil, (acp3)w, and 2,6-diaminopurine. Alternatively, the antisense nucleic acid can be produced biologically using an expression vector into which a nucleic acid has been subcloned in an antisense orientation (i.e., RNA transcribed from the inserted nucleic acid will be of an antisense orientation to a target nucleic acid of interest).
The antisense nucleic acid molecules described herein can be prepared in vitro and administered to a mammal, e.g., a human. Alternatively, they can be generated in situ such that they hybridize with or bind to cellular mRNA and/or genomic DNA encoding an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein to thereby inhibit expression, e.g., by inhibiting transcription and/or translation. The hybridization can be by conventional nucleotide complementarities to form a stable duplex, or, for example, in the case of an antisense nucleic acid molecule that binds to DNA duplexes, through specific interactions in the major groove of the double helix. The antisense nucleic acid molecules can be delivered to a mammalian cell using a vector (e.g., a lentivirus, a retrovirus, or an adenovirus vector).
An antisense nucleic acid can be an α-anomeric nucleic acid molecule. An α-anomeric nucleic acid molecule forms specific double-stranded hybrids with complementary RNA in which, contrary to the usual, β-units, the strands run parallel to each other (Gaultier et al., Nucleic Acids Res. 15:6625-6641, 1987). The antisense nucleic acid can also comprise a 2′-O-methylribonucleotide (Inoue et al., Nucleic Acids Res. 15:6131-6148, 1987) or a chimeric RNA-DNA analog (Inoue et al., FEBS Lett. 215:327-330, 1987). Non-limiting examples of antisense nucleic acids are described in Vaknin-Dembinsky et al., J. Immunol. 176(12): 7768-7774, 2006.
Another example of an inhibitory nucleic acid is a ribozyme that has specificity for a nucleic acid encoding an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein (e.g., specificity for an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA, e.g., specificity for any one of SEQ ID NOs: 1-12). Ribozymes are catalytic RNA molecules with ribonuclease activity that are capable of cleaving a single-stranded nucleic acid, such as an mRNA, to which they have a complementary region. Thus, ribozymes (e.g., hammerhead ribozymes (described in Haselhoff and Gerlach, Nature 334:585-591, 1988)) can be used to catalytically cleave mRNA transcripts to thereby inhibit translation of the protein encoded by the mRNA. A ribozyme having specificity for an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA can be designed based upon the nucleotide sequence of any of the IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, and IL-23R mRNA sequences disclosed herein. For example, a derivative of a Tetrahymena L-19 IVS RNA can be constructed in which the nucleotide sequence of the active site is complementary to the nucleotide sequence to be cleaved in an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA (see, e.g., U.S. Pat. Nos. 4,987,071 and 5,116,742). Alternatively, an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA can be used to select a catalytic RNA having a specific ribonuclease activity from a pool of RNA molecules. See, e.g., Bartel et al., Science 261:1411-1418, 1993.
An inhibitory nucleic acid can also be a nucleic acid molecule that forms triple helical structures. For example, expression of an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein can be inhibited by targeting nucleotide sequences complementary to the regulatory region of the gene encoding the IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein (e.g., the promoter and/or enhancer, e.g., a sequence that is at least 1 kb, 2 kb, 3 kb, 4 kb, or 5 kb upstream of the transcription initiation start state) to form triple helical structures that prevent transcription of the gene in target cells. See generally Helene, Anticancer Drug Des. 6(6):569-84, 1991; Helene, Ann. N.Y. Acad. Sci. 660:27-36, 1992; and Maher, Bioassays 14(12):807-15, 1992.
In various embodiments, inhibitory nucleic acids can be modified at the base moiety, sugar moiety, or phosphate backbone to improve, e.g., the stability, hybridization, or solubility of the molecule. For example, the deoxyribose phosphate backbone of the nucleic acids can be modified to generate peptide nucleic acids (see, e.g., Hyrup et al., Bioorganic Medicinal Chem. 4(1):5-23, 1996). Peptide nucleic acids (PNAs) are nucleic acid mimics, e.g., DNA mimics, in which the deoxyribose phosphate backbone is replaced by a pseudopeptide backbone and only the four natural nucleobases are retained. The neutral backbone of PNAs allows for specific hybridization to DNA and RNA under conditions of low ionic strength. The synthesis of PNA oligomers can be performed using standard solid phase peptide synthesis protocols (see, e.g., Perry-O'Keefe et al., Proc. Natl. Acad. Sci. U.S.A. 93:14670-675, 1996). PNAs can be used as antisense or antigene agents for sequence-specific modulation of gene expression by, e.g., inducing transcription or translation arrest or inhibiting replication.
PNAs can be modified, e.g., to enhance their stability or cellular uptake, by attaching lipophilic or other helper groups to PNA, by the formation of PNA-DNA chimeras, or by the use of liposomes or other techniques of drug delivery known in the art. For example, PNA-DNA chimeras can be generated which may combine the advantageous properties of PNA and DNA. Such chimeras allow DNA recognition enzymes, e.g., RNAse H and DNA polymerases, to interact with the DNA portion while the PNA portion would provide high binding affinity and specificity. PNA-DNA chimeras can be linked using linkers of appropriate lengths selected in terms of base stacking, number of bonds between the nucleobases, and orientation.
The synthesis of PNA-DNA chimeras can be performed as described in Finn et al., Nucleic Acids Res. 24:3357-63, 1996. For example, a DNA chain can be synthesized on a solid support using standard phosphoramidite coupling chemistry and modified nucleoside analogs. Compounds such as 5′-(4-methoxytrityl)amino-5′-deoxy-thymidine phosphoramidite can be used as a link between the PNA and the 5′ end of DNA (Mag et al., Nucleic Acids Res. 17:5973-88, 1989). PNA monomers are then coupled in a stepwise manner to produce a chimeric molecule with a 5′ PNA segment and a 3′ DNA segment (Finn et al., Nucleic Acids Res. 24:3357-63, 1996). Alternatively, chimeric molecules can be synthesized with a 5′ DNA segment and a 3′ PNA segment (Petersen et al., Bioorganic Med. Chem. Lett. 5:1119-11124, 1995).
In some embodiments, the inhibitory nucleic acids can include other appended groups such as peptides, or agents facilitating transport across the cell membrane (see, Letsinger et al., Proc. Natl. Acad. Sci. U.S.A. 86:6553-6556, 1989; Lemaitre et al., Proc. Natl. Acad. Sci. U.S.A. 84:648-652, 1989; and WO 88/09810). In addition, the inhibitory nucleic acids can be modified with hybridization-triggered cleavage agents (see, e.g., Krol et al., Bio/Techniques 6:958-976, 1988) or intercalating agents (see, e.g., Zon, Pharm. Res. 5:539-549, 1988). To this end, the oligonucleotide may be conjugated to another molecule, e.g., a peptide, hybridization triggered cross-linking agent, transport agent, hybridization-triggered cleavage agent, etc.
Another means by which expression of an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA can be decreased in a mammalian cell is by RNA interference (RNAi). RNAi is a process in which mRNA is degraded in host cells. To inhibit an mRNA, double-stranded RNA (dsRNA) corresponding to a portion of the gene to be silenced (e.g., a gene encoding an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R protein) is introduced into a mammalian cell. The dsRNA is digested into 21-23 nucleotide-long duplexes called short interfering RNAs (or siRNAs), which bind to a nuclease complex to form what is known as the RNA-induced silencing complex (or RISC). The RISC targets the homologous transcript by base pairing interactions between one of the siRNA strands and the endogenous mRNA. It then cleaves the mRNA about 12 nucleotides from the 3′ terminus of the siRNA (see Sharp et al., Genes Dev. 15:485-490, 2001, and Hammond et al., Nature Rev. Gen. 2:110-119, 2001).
RNA-mediated gene silencing can be induced in a mammalian cell in many ways, e.g., by enforcing endogenous expression of RNA hairpins (see, Paddison et al., Proc. Natl. Acad. Sci. U.S.A. 99:1443-1448, 2002) or, as noted above, by transfection of small (21-23 nt) dsRNA (reviewed in Caplen, Trends Biotech. 20:49-51, 2002). Methods for modulating gene expression with RNAi are described, e.g., in U.S. Pat. No. 6,506,559 and US 2003/0056235, which are hereby incorporated by reference.
Standard molecular biology techniques can be used to generate siRNAs. Short interfering RNAs can be chemically synthesized, recombinantly produced, e.g., by expressing RNA from a template DNA, such as a plasmid, or obtained from commercial vendors, such as Dharmacon. The RNA used to mediate RNAi can include synthetic or modified nucleotides, such as phosphorothioate nucleotides. Methods of transfecting cells with siRNA or with plasmids engineered to make siRNA are routine in the art.
The siRNA molecules used to decrease expression of an IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA can vary in a number of ways. For example, they can include a 3′ hydroxyl group and strands of 21, 22, or 23 consecutive nucleotides. They can be blunt ended or include an overhanging end at either the 3′ end, the 5′ end, or both ends. For example, at least one strand of the RNA molecule can have a 3′ overhang from about 1 to about 6 nucleotides (e.g., 1-5, 1-3, 2-4 or 3-5 nucleotides (whether pyrimidine or purine nucleotides) in length. Where both strands include an overhang, the length of the overhangs may be the same or different for each strand.
To further enhance the stability of the RNA duplexes, the 3′ overhangs can be stabilized against degradation (by, e.g., including purine nucleotides, such as adenosine or guanosine nucleotides or replacing pyrimidine nucleotides by modified analogues (e.g., substitution of uridine 2-nucleotide 3′ overhangs by 2′-deoxythymidine is tolerated and does not affect the efficiency of RNAi). Any siRNA can be used in the methods of decreasing IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R mRNA, provided it has sufficient homology to the target of interest (e.g., a sequence present in any one of SEQ ID NOs: 1-15, e.g., a target sequence encompassing the translation start site or the first exon of the mRNA). There is no upper limit on the length of the siRNA that can be used (e.g., the siRNA can range from about 21 base pairs of the gene to the full length of the gene or more (e.g., about 20 to about 30 base pairs, about 50 to about 60 base pairs, about 60 to about 70 base pairs, about 70 to about 80 base pairs, about 80 to about 90 base pairs, or about 90 to about 100 base pairs).
Non-limiting examples of siRNAs targeting IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R are described in Tan et al., J. Alzheimers Dis. 38(3): 633-646, 2014; Niimi et al., J. Neuroimmunol. 254(1-2):39-45, 2013. Non-limiting examples of short hairpin RNA (shRNA) targeting IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R are described in Bak et al., BMC Dermatol. 11:5, 2011.
Non-limiting examples of inhibitory nucleic acids are microRNAs (e.g., microRNA-29 (Brain et al., Immunity 39(3):521-536, 2013), miR-10a (Xue et al., J. Immunol. 187(11):5879-5886, 2011), microRNA-155 (Podsiad et al., Am. J. Physiol. Lung Cell Mol. Physiol. 310(5):L465-75, 2016).
In some embodiments, a therapeutically effective amount of an inhibitory nucleic acid targeting IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R can be administered to a subject (e.g., a human subject) in need thereof.
In some embodiments, the inhibitory nucleic acid can be about 10 nucleotides to about 40 nucleotides (e.g., about 10 to about 30 nucleotides, about 10 to about 25 nucleotides, about 10 to about 20 nucleotides, about 10 to about 15 nucleotides, 10 nucleotides, 11 nucleotides, 12 nucleotides, 13 nucleotides, 14 nucleotides, 15 nucleotides, 16 nucleotides, 17 nucleotides, 18 nucleotides, 19 nucleotides, 20 nucleotides, 21 nucleotides, 22 nucleotides, 23 nucleotides, 24 nucleotides, 25 nucleotides, 26 nucleotides, 27 nucleotides, 28 nucleotides, 29 nucleotides, 30 nucleotides, 31 nucleotides, 32 nucleotides, 33 nucleotides, 34 nucleotides, 35 nucleotides, 36 nucleotides, 37 nucleotides, 38 nucleotides, 39 nucleotides, or 40 nucleotides) in length. One skilled in the art will appreciate that inhibitory nucleic acids may comprise at least one modified nucleic acid at either the 5′ or 3′end of DNA or RNA.
Any of the inhibitor nucleic acids described herein can be formulated for administration to the gastrointestinal tract. See, e.g., the formulation methods described in US 2016/0090598 and Schoellhammer et al., Gastroenterology, doi: 10.1053/j.gastro.2017.01.002, 2017.
As is known in the art, the term “thermal melting point (Tm)” refers to the temperature, under defined ionic strength, pH, and inhibitory nucleic acid concentration, at which 50% of the inhibitory nucleic acids complementary to the target sequence hybridize to the target sequence at equilibrium. In some embodiments, an inhibitory nucleic acid can bind specifically to a target nucleic acid under stringent conditions, e.g., those in which the salt concentration is at least about 0.01 to 1.0 M Na ion concentration (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30° C. for short oligonucleotides (e.g., 10 to 50 nucleotide). Stringent conditions can also be achieved with the addition of destabilizing agents such as formamide.
In some embodiments of any of the inhibitory nucleic acids described herein, the inhibitory nucleic acid binds to a target nucleic acid (e.g., a nucleic acid encoding any one of IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R β1, IL-12R β2, or IL-23R) with a Tm of greater than 20° C., greater than 22° C., greater than 24° C., greater than 26° C., greater than 28° C., greater than 30° C., greater than 32° C., greater than 34° C., greater than 36° C., greater than 38° C., greater than 40° C., greater than 42° C., greater than 44° C., greater than 46° C., greater than 48° C., greater than 50° C., greater than 52° C., greater than 54° C., greater than 56° C., greater than 58° C., greater than 60° C., greater than 62° C., greater than 64° C., greater than 66° C., greater than 68° C., greater than 70° C., greater than 72° C., greater than 74° C., greater than 76° C., greater than 78° C., or greater than 80° C., e.g., as measured in phosphate buffered saline using a UV spectrophotometer.
In some embodiments of any of the inhibitor nucleic acids described herein, the inhibitory nucleic acid binds to a target nucleic acid (e.g., a nucleic acid encoding any one of IL-12A (p35), IL-12B (p40), IL-23 (p19), IL-12R 01, IL-12R β2, or IL-23R) with a Tm of about 20° C. to about 80° C., about 78° C., about 76° C., about 74° C., about 72° C., about 70° C., about 68° C., about 66° C., about 64° C., about 62° C., about 60° C., about 58° C., about 56° C., about 54° C., about 52° C., about 50° C., about 48° C., about 46° C., about 44° C., about 42° C., about 40° C., about 38° C., about 36° C., about 34° C., about 32° C., about 30° C., about 28° C., about 26° C., about 24° C., or about 22° C. (inclusive); about 22° C. to about 80° C., about 78° C., about 76° C., about 74° C., about 72° C., about 70° C., about 68° C., about 66° C., about 64° C., about 62° C., about 60° C., about 58° C., about 56° C., about 54° C., about 52° C., about 50° C., about 48° C., about 46° C., about 44° C., about 42° C., about 40° C., about 38° C., about 36° C., about 34° C., about 32° C., about 30° C., about 28° C., about 26° C., or about 24° C.

As disclosed herein, in some embodiments, a method of treating a disease of the gastrointestinal tract comprises administering to the subject a pharmaceutical formulation. In some embodiments, the pharmaceutical formulation is delivered to a section or subsection of the GI tract containing one or more sites of disease by one of various methods. For example, the pharmaceutical formulation may be delivered via a medical device such as an endoscope, ingestible device, or reservoir; the pharmaceutical formulation may be a solid dosage form, a liquid dosage form, a suppository or an enema for rectal administration with different types of release such as sustained or delayed release.
In one embodiment, the pharmaceutical formulation is delivered to a section or subsection of the GI tract containing one or more sites of disease by an endoscope, ingestible device, or reservoir containing the pharmaceutical formulation.
The GI tract can be imaged using endoscopes, or more recently, by ingestible devices that are swallowed. Direct visualization of the GI mucosa is useful to detect subtle mucosal alterations, as in inflammatory bowel diseases, as well as any flat or sessile lesions.
The technology behind standard colonoscopy consists of a long, semi-rigid insertion tube with a steerable tip (stiff if compared to the colon), which is pushed by the physician from the outside. However, invasiveness, patient discomfort, fear of pain, and—more often than not—the need for conscious sedation limit the take-up of screening colonoscopy. Diagnosis and treatment in the GI tract are dominated by the use of flexible endoscopes. A few large companies, namely Olympus Medical Systems Co. (Tokyo, Japan), Pentax Medical Co. (Montvale, N.J., USA), Fujinon, Inc. (Wayne, N.J., USA) and Karl Storz GmbH & Co. KG (Tuttlingen, Germany), cover the majority of the market in flexible GI endoscopy.
Endoscopes may comprise a catheter. As an example, the catheter may be a spray catheter. As an example, a spray catheter may be used to deliver dyes for diagnostic purposes. As an example, a spray catheter may be used to deliver a therapeutic agent at the site of disease in the GI tract. For example, the Olympus PW-205V is a ready-to-use spray catheter that enables efficient spraying for maximal differentiation of tissue structures during endoscopy, but may also be used to deliver drugs diseased tissue.
In a review of robotic endoscopic capsules, Journal of Micro-Bio Robotics 11.1-4 (2016): 1-18, Ciuti et al. state that progress in micro-electromechanical systems (MEMS) technologies have led to the development of new endoscopic capsules with enhanced diagnostic capabilities, in addition to traditional visualization of mucosa (embedding, e.g., pressure, pH, blood detection and temperature sensors).
In addition to, or as an alternative to, directly visualizing the GI tract, one or more different mechanisms can be used to determine the location of an ingestible device within the GI tract. Various implementations may be used for localization of ingestible devices within the GI tract.
For example, certain implementations can include one or more electromagnetic sensor coils, magnetic fields, electromagnetic waves, electric potential values, ultrasound positioning systems, gamma scintigraphy techniques or other radio-tracker technology have been described by others. Alternatively, imaging can be used to localize, for example, using anatomical landmarks or more complex algorithms for 3D reconstruction based on multiple images. Other technologies rely on radio frequency, which relies on sensors placed externally on the body to receive the strength of signals emitted by the capsule. Ingestible devices may also be localized based on reflected light in the medium surrounding the device; pH; temperature; time following entry of the device into the GI tract of the subject; time following ingestion; and/or acoustic signals.
The disclosure provides an ingestible device, as well as related systems and methods that provide for determining the position of the ingestible device within the GI tract of a subject with very high accuracy. In some embodiments, the ingestible device can autonomously determine its position within the GI tract of the subject.
Typically, the ingestible device includes one or more processing devices, and one more machine readable hardware storage devices. In some embodiments, the one or more machine readable hardware storage devices store instructions that are executable by the one or more processing devices to determine the location of the ingestible device in a portion of a GI tract of the subject. In certain embodiments, the one or more machine readable hardware storage devices store instructions that are executable by the one or more processing devices to transmit data to an external device (e.g., a base station external to the subject, such as a base station carried on an article worn by the subject) capable of implementing the data to determine the location of the device within the GI tract of the subject.
In some embodiments, the location of the ingestible device within the GI tract of the subject can be determined to an accuracy of at least about 85%, e.g., at least about 90%, at least about 95%, at least about 97%, at least about 98%, at least about 99%, or about 100%.

In some embodiments, first end portion 104 and second end portion 106 of ingestible device 100 may be manufactured separately, and may be affixed together by a connecting portion 112.
In some embodiments, ingestible device 100 may include an optically transparent window 114. Optically transparent window 114 may be transparent to various types of illumination in the visible spectrum, infrared spectrum, or ultraviolet light spectrum, and ingestible device 100 may have various sensors and illuminators located within the housing 102, and behind the transparent window 114. This may allow ingestible device 100 to be configured to transmit illumination at different wavelengths through transparent window 114 to an environment external to housing 102 of ingestible device 100, and to detect a reflectance from a portion of the illumination that is reflected back through transparent window 114 from the environment external to housing 102. Ingestible device 100 may then use the detected level of reflectance in order to determine a location of ingestible device 100 within a GI tract. In some embodiments, optically transparent window 114 may be of any shape and size, and may wrap around the circumference of ingestible device 100. In this case, ingestible device 100 may have multiple sets of sensors and illuminators positioned at different locations azimuthally behind window 114.
In some embodiments, ingestible device 100 may optionally include an opening 116 in the second wall portion 110. In some embodiments, the second wall portion 110 may be configured to rotate around the longitudinal axis of ingestible device 100 (e.g., by means of a suitable motor or other actuator housed within ingestible device 100). This may allow ingestible device 100 to obtain a fluid sample from the GI tract, or release a substance into the GI tract, through opening 116.
Ingestible device 100 may include a printed circuit board (PCB) 120, and a battery 128 configured to power PCB 120. PCB 120 may include a programmable microcontroller, and control and memory circuitry for holding and executing firmware or software for coordinating the operation of ingestible device 100, and the various components of ingestible device 100. For example, PCB 120 may include memory circuitry for storing data, such as data sets of measurements collected by sensing sub-unit 126, or instructions to be executed by control circuitry to implement a localization process, such as, for example, one or more of the processes, discussed herein, including those discussed below in connection with one or more of the associated flow charts. PCB 120 may include a detector 122 and an illuminator 124, which together form sensing sub-unit 126. In some embodiments, control circuitry within PCB 120 may include processing units, communication circuitry, or any other suitable type of circuitry for operating ingestible device 100. For illustrative purposes, only a single detector 122 and a single illuminator 124 forming a single sensing sub-unit 126 are shown. However, it is understood that in some embodiments there may be multiple sensing sub-units, each with a separate illuminator and detector, within ingestible device 100. For example, there may be several sensing sub-units spaced azimuthally around the circumference of the PCB 120, which may enable ingestible device 100 to transmit illumination and detect reflectances or ambient light in all directions around the circumference of the device. In some embodiments, sensing sub-unit 126 may be configured to generate an illumination using illuminator 124, which is directed through the window 114 in a radial direction away from ingestible device 100. This illumination may reflect off of the environment external to ingestible device 100, and the reflected light coming back into ingestible device 100 through window 114 may be detected as a reflectance by detector 122.
In some embodiments, window 114 may be of any suitable shape and size. For example, window 114 may extend around a full circumference of ingestible device 100. In some embodiments there may be a plurality of sensing sub-units (e.g., similar to sensing sub-unit 126) located at different positions behind the window. For example, three sensing sub-units may be positioned behind the window at the same longitudinal location, but spaced 120 degrees apart azimuthally. This may enable ingestible device 100 to transmit illuminations in all directions radially around ingestible device 100, and to measure each of the corresponding reflectances.
In some embodiments, illuminator 124 may be capable of producing illumination at a variety of different wavelengths in the ultraviolet, infrared, or visible spectrum. For example, illuminator 124 may be implemented by using Red-Green-Blue Light-Emitting diode packages (RGB-LED). These types of RGB-LED packages are able to transmit red, blue, or green illumination, or combinations of red, blue, or green illumination. Similarly, detector 122 may be configured to sense reflected light of the same wavelengths as the illumination produced by illuminator 124. For example, if illuminator 124 is configured to produce red, blue, or green illumination, detector 122 may be configured to detect different reflectances produced by red, blue, or green illumination (e.g., through the use of an appropriately configured photodiode). These detected reflectances may be stored by ingestible device 100 (e.g., within memory circuitry of PCB 120), and may then be used by ingestible device 100 in determining a location of ingestible device 100 within the GI tract (e.g., through the use of process 500 (
It is understood that ingestible device 100 is intended to be illustrative, and not limiting. It will be understood that modifications to the general shape and structure of the various devices and mechanisms described in relation to
Shortly after ingestible device 300 is ingested, ingestible device will traverse the esophagus 302, which may connect the subject's mouth to a stomach 306. In some embodiments, ingestible device 300 may be configured to determine that it has entered the esophagus portion GI tract by measuring the amount and type of light (e.g., via detector 122 (
In some embodiments, ingestible device 300 may be configured to detect a transition from esophagus 302 to stomach 306 by passing through sphincter 304. In some embodiments, ingestible device 300 may be configured to determine whether it has entered stomach 306 based at least in part on a plurality of parameters, such as but not limited to the use of light or temperature measurements (e.g., via detector 122 (
Stomach 306 is a relatively large, open, and cavernous organ, and therefore ingestible device 300 may have a relatively large range of motion. By comparison, the motion of ingestible device 300 is relatively restricted within the tube-like structure of the duodenum 310, the jejunum 314, and the ileum (not shown), all of which collectively form the small intestine. Additionally, the interior of stomach 306 has distinct optical properties from duodenum 310 and jejunum 314, which may enable ingestible device 300 to detect a transition from stomach 306 to duodenum 310 through the appropriate use of measured reflectances (e.g., through the use of reflectances measured by detector 122 (
In some embodiments, ingestible device 300 may be configured to detect a pyloric transition from stomach 306 to duodenum 310 through the pylorus 308. For instance, in some embodiments, ingestible device 300 may be configured to periodically generate illumination in the green and blue wavelengths (e.g., via illuminator 124 (
Similarly, in some embodiments, ingestible device 300 may be configured to detect a reverse pyloric transition from duodenum 310 to stomach 306. Ingestible device 300 will typically transition naturally from stomach 306 to duodenum 310, and onward to jejunum 314 and the remainder of the GI tract. However, similar to other ingested substances, ingestible device 300 may occasionally transition from duodenum 310 back to stomach 306 as a result of motion of the subject, or due to the natural behavior of the organs with the GI tract. To accommodate this possibility, ingestible device 300 may be configured to continue to periodically generate illumination in the green and blue wavelengths (e.g., via illuminator 124 (
After entering duodenum 310, ingestible device 300 may be configured to detect a transition to the jejunum 314 through the duodenojejunal flexure 312. For example, ingestible device 300 may be configured to use reflectances to detect peristaltic waves within the jejunum 314, caused by the contraction of the smooth muscle tissue lining the walls of the jejunum 314. In particular, ingestible device 300 may be configured to begin periodically transmitting illumination (and measuring the resulting reflectances (e.g., via detector 122 and illuminator 124 of sensing sub-unit 126 (
Diagram 410 depicts ingestible device 400 within the jejunum, when the walls 406 of the jejunum are relaxed. In some embodiments, the confined tube-like structure of the jejunum naturally causes ingestible device 400 to be oriented longitudinally along the length of the jejunum, with window 404 facing walls 406. In this orientation, ingestible device 400 may use sensing sub-unit 402 to generate illumination (e.g., via illuminator 124 (
Diagram 420 depicts ingestible device 400 within the jejunum, when the walls 406 of the jejunum begin to contract and form a peristaltic wave. Diagram 420 depicts contracting portion 408A of wall 406A and contracting portion 408B of wall 406B (collectively, contracting portion 408 of wall 406) that form a peristaltic wave within the jejunum. The peristaltic wave proceeds along the length of the jejunum as different portions of wall 406 contract and relax, causing it to appear as if contracting portions 408 of wall 406 proceed along the length of the jejunum (i.e., as depicted by contracting portions 408 proceeding from left to right in diagrams 410-430). While in this position, ingestible device 400 may detect a similar level of reflectance (e.g., through the use of illuminator 124 and detector 122 of sensing sub-unit 126 (
Diagram 430 depicts ingestible device 400 within the jejunum, when the walls 406 of the jejunum continue to contract, squeezing around ingestible device 400. As the peristaltic wave proceeds along the length of the jejunum, contracting portions 408 of wall 406 may squeeze tightly around ingestible device 400, bringing the inner surface of wall 406 into contact with window 404. While in this position, ingestible device 400 may detect a change in a reflectance detected as a result of illumination produced by sensing sub-unit 402. The absolute value of the change in the measured reflectance may depend on several factors, such as the optical properties of the window 404, the spectral components of the illumination, and the optical properties of the walls 406. However, ingestible device 400 may be configured to store a data set with the reflectance values over time, and search for periodic changes in the data set consistent with the frequency of the peristaltic waves (e.g., by analyzing the data set in the frequency domain, and searching for peaks between 0.1 Hz to 0.2 Hz). This may enable ingestible device 400 to detect muscle contractions due to peristaltic waves without foreknowledge of the exact changes in reflectance signal amplitude that may occur as a result of detecting the muscle contractions of the peristaltic wave. An example procedure for detecting muscle contractions is discussed further in relation to
Diagram 440 depicts ingestible device 400 within the jejunum, when the peristaltic wave has moved past ingestible device 400. Diagram 440 depicts contracting portions 408 that form the peristaltic wave within the jejunum having moved past the end of ingestible device 400. The peristaltic wave proceeds along the length of the jejunum as different portions of wall 406 contract and relax, causing it to appear as if contracting portions 408 of wall 406 proceed along the length of the jejunum (i.e., as depicted by contracting portions 408 proceeding from left to right in diagrams 410-430). While in this position, ingestible device 400 may detect a similar level of reflectance (e.g., through the use of illuminator 124 and detector 122 of sensing sub-unit 126 (
Depending on the species of the subject, peristaltic waves may occur with relatively predictable regularity. After the peristaltic wave has passed over ingestible device 400 (e.g., as depicted in diagram 440), the walls 406 of the jejunum may relax again (e.g., as depicted in diagram 410), until the next peristaltic wave begins to form. In some embodiments, ingestible device 400 may be configured to continue to gather reflectance value data while it is within the GI tract, and may store a data set with the reflectance values over time. This may allow ingestible device 400 to detect each of the muscle contractions as the peristaltic wave passes over ingestible device 400 (e.g., as depicted in diagram 430), and may enable ingestible device 400 to both count the number of muscle contractions that occur, and to determine that a current location of the ingestible device 400 is within the jejunum. For example, ingestible device 400 may be configured to monitor for possible muscle contractions while is inside either the stomach or the duodenum, and may determine that ingestible device 400 has moved to the jejunum in response to detecting a muscle contraction consistent with a peristaltic wave.
At 502, the ingestible device (e.g., ingestible device 100, 300, or 400) gathers measurements (e.g., through detector 122 (
At 504, the ingestible device (e.g., ingestible device 100, 300, or 400) determines (e.g., via control circuitry within PCB 120 (
At 506, the ingestible device (e.g., ingestible device 100, 300, or 400) waits for a transition from the esophagus to the stomach (e.g., from esophagus 302 to stomach 306 (
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may also determine it has entered the stomach based on measurements of pH or temperature. For example, ingestible device 100 may be configured to determine that it has entered the stomach if a temperature of ingestible device has increased to at least 31 degrees Celsius (i.e., consistent with the temperature inside the stomach), or if a measured pH of the environment surrounding ingestible device 100 is sufficiently acidic (i.e., consistent with the acidic nature of gastric juices that may be found inside the stomach).
At 508, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data indicating the ingestible device has entered the stomach (e.g., stomach 306 (
In some embodiments, process 500 may also simultaneously proceed from 508 to 520, where ingestible device 100 may be configured to gather data in order to detect muscle contractions and detect entry into the jejunum (e.g., jejunum 314 (
At 510, the ingestible device (e.g., ingestible device 100, 300, or 400) gathers measurements of green and blue reflectance levels (e.g., through the use of illuminator 124 and detector 122 of sensing sub-unit 126 (
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may be configured to detect a first reflectance based on generating an illumination of a first wavelength in approximately the green spectrum of light (between 495-600 nm), and detecting a second reflectance based on generating an illumination of the second wavelength in approximately the blue spectrum of light (between 400-495 nm). In some embodiments, the ingestible device may ensure that the illumination in the green spectrum and the illumination in the blue spectrum have wavelengths separated by at least 50 nm. This may enable ingestible device 100 to sufficiently distinguish between the two wavelengths when detecting the reflectances (e.g., via detector 122 (
At 512, the ingestible device (e.g., ingestible device 100, 300, or 400) determines (e.g., using control circuitry within PCB 120 (
In some embodiments, the first time that ingestible device 100 detects a transition from the stomach (e.g., stomach 306 (
At 514, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data indicating that the ingestible device has entered the duodenum (e.g., duodenum 310 (
At 516, the ingestible device (e.g., ingestible device 100, 300, or 400) gathers measurements (e.g., via sensing sub-unit 126 (
At 518, the ingestible device (e.g., ingestible device 100, 300, or 400) determines a transition from the duodenum (e.g., duodenum 310 (
At 520, the ingestible device (e.g., ingestible device 100, 300, or 400) gathers periodic measurements of the reflectance levels (e.g., via sensing sub-unit 126 (
At 522, the ingestible device (e.g., ingestible device 100, 300, or 400) determines (e.g., via control circuitry within PCB 120 (
At 524, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data (e.g., within memory circuitry of PCB 120 (
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may also determine that it has entered the jejunum (e.g., jejunum 314 (
For illustrative purposes, 512-518 of process 500 describe the ingestible device (e.g., ingestible device 100, 300, or 400) measuring green reflectances and blue reflectances, calculating a ratio of the two reflectances, and using this information to determine when the ingestible device has transitioned between the duodenum and stomach. However, in some embodiments, other wavelengths of light may be used other than green and blue, provided that the wavelengths of light chosen have different reflective properties within the stomach and the duodenum (e.g., as a result of different reflection coefficients of the stomach tissue and the tissue of the duodenum).
It will be understood that the steps and descriptions of the flowcharts of this disclosure, including
At 602, the ingestible device (e.g., ingestible device 100, 300, or 400) retrieves a data set (e.g., from memory circuitry within PCB 120 (
At 604, the ingestible device (e.g., ingestible device 100, 300, or 400) includes a new measurement (e.g., as made with sensing sub-unit 126 (
At 606, the ingestible device (e.g., ingestible device 100, 300, or 400) retrieves a first subset of recent data by applying a first sliding window filter to the data set. For example, ingestible device 100 may use a sliding window filter to obtain a predetermined amount of the most recent data within the data set, which may include any new values of the ratio of the measured green reflectance level to the measured blue reflectance level obtained at 604. For instance, the ingestible device may be configured to select between ten and forty data points from the data set, or ingestible device 100 may be configured to select a predetermined range of data values between fifteen seconds of data and five minutes of data. In some embodiments, other ranges of data may be selected, depending on how frequently measurements are recorded, and the particular application at hand. For instance, any suitable amount of data may be selected in the sliding window, provided that it is sufficient to detect statistically significant differences between the data selected in a second sliding window (e.g., the second subset of data selected at 614).
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may also be configured to remove outliers from the data set, or to smooth out unwanted noise in the data set. For example, ingestible device 100 may select the first subset of data, or any other subset of data, by first obtaining a raw set of values by applying a window filter to the data set (e.g., selecting a particular range of data to be included). Ingestible device 100 may then be configured to identify outliers in the raw set of values; for instance, by identifying data points that are over three standard deviations away from the mean value of the raw set of values, or any other suitable threshold. Ingestible device 100 may then determine the subset of data by removing outliers from the raw set of values. This may enable ingestible device 100 to avoid spurious information when determining whether or not it is located within the stomach or the duodenum.
At 608, the ingestible device (e.g., ingestible device 100, 300, or 400) determines whether the most recently detected location was the duodenum (e.g., duodenum 310 (
Process 600 proceeds from 608 to 610 when the ingestible device determined that it was most recently in the duodenum. At 610, the ingestible device (e.g., ingestible device 100, 300, or 400) determines (e.g., via control circuitry within PCB 120 (
At 612, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data indicating a reverse pyloric transition from the duodenum to the stomach was detected. For example, ingestible device 100 may store a data flag (e.g., within memory circuitry of PCB 120 (
Process 600 proceeds from 608 to 614 when the ingestible device determined that it was not most recently in the duodenum (e.g., as a result of having most recently been in the stomach instead). At 614, the ingestible device (e.g., ingestible device 100, 300, or 400) retrieves a second subset of previous data by applying a second sliding window filter to the data set. For example, ingestible device 100 may use a sliding window filter to obtain a predetermined amount of older data from a past time range, which may be separated from recent time range used to select the first subset of data gathered at 606 by a predetermined period of time. In some embodiments, any suitable amount of data may be selected by the first and second window filters, and the first and second window filters may be separated by any appropriate predetermined amount of time. For example, in some embodiments, the first window filter and the second window filter may each be configured to select a predetermined range of data values from the data set, the predetermined range being between fifteen seconds of data and five minutes of data. In some embodiments, the recent measurements and the past measurements may then be separated by a predetermined period of time that is between one to five times the predetermined range of data values. For instance, ingestible device 100 may select the first subset of data and the second subset of data to each be one minute of data selected from the dataset (i.e., selected to have a predetermined range of one minute), and the first subset of data and the second subset of data are selected from recorded measurements that are at least two minutes apart (i.e., the predetermined period of time is two minutes, which is twice the range used to select the subsets of data using the window filters). As another example, ingestible device 100 may select the first subset of data and the second subset of data to each be five minutes of data selected from the dataset (i.e., selected to have a predetermined range of five minutes), and the first subset of data and the second subset of data are selected from recorded measurements that are at least 10 minutes apart (i.e., the predetermined period of time is two minutes, which is twice the range used to select the subsets of data using the window filters).
In some embodiments, if ingestible device 100 recently transitioned to the stomach from the duodenum (e.g., as determined by checking for recent data stored within ingestible device 100 at 612), ingestible device 100 may select the second subset of data at 614 from a time frame when ingestible device 100 is known to be within the stomach. In some embodiments, ingestible device 100 may alternately select a previously recorded average and standard deviation for ratios of green reflectances and blue reflectances within the stomach (e.g., an average and standard deviation typical of data recorded within the stomach, as previously recorded within memory circuitry of PCB 120 at 620) in place of the second subset of data. In this case, ingestible device 100 may simply use the previously recorded average and previously recorded standard deviation when making a determination at 616, rather than expending resources to calculate the mean and standard deviation of the second subset.
At 616, the ingestible device (e.g., ingestible device 100, 300, or 400) determines whether the difference between the mean of the second subset and the mean of the first subset is greater than a predetermined multiple of the standard deviation of the first subset. For example, ingestible device 100 may compute a difference between a mean of the first subset of recent data and a mean of a second subset of past data, and determine whether this difference is greater than three times the standard deviation of the second subset of past data. In some embodiments, it is understood that any convenient threshold level may be used other than three times the standard deviation, such as any value between one and five times the standard deviation. Also, in some embodiments, the ingestible device may instead set the threshold level based on the standard deviation of the second subset instead of the first subset. In response to determining that the difference between the mean of the first subset and the mean of the second subset is greater than a predetermined multiple of the standard deviation of the second subset, process 600 proceeds to 618. Otherwise, process 600 proceeds back to 604, where the ingestible device 604 continues to gather new data to be used in monitoring for transitions between the stomach (e.g., stomach 306 (
At 618, the ingestible device (e.g., ingestible device 100, 300, or 400) determines (e.g., via control circuitry within PCB 120 (
At 620, the ingestible device (e.g., ingestible device 100, 300, or 400) stores the mean of the second subset as an average G/B signal in the stomach. For example, ingestible device 100 may be configured to store the mean of the second subset of past data (e.g., store within memory circuitry of PCB 120 (
At 622, the ingestible device (e.g., ingestible device 100, 300, or 400) determines whether a difference of the mean of the first subset of recent data to the mean of the second subset of past data is greater than a predetermined threshold, “M”. In some embodiments, the predetermined threshold, “M,” will be sufficiently large to ensure that the mean of the first subset is substantially larger than the mean of the second subset, and may enable ingestible device 100 to ensure that it detected an actual transition to the duodenum. This may be particularly advantageous when the determination made at 616 is potentially unreliable due to the standard deviation of the second subset of past data being abnormally small. For example, a typical value of the predetermined threshold “M,” may be on the order of 0.1 to 0.5. If ingestible device 100 determines that the difference of the mean of the first subset of recent data to the second subset of past data is greater than a predetermined threshold, process 600 proceeds to 624 to store data indicating that a pyloric transition from the stomach to the duodenum (e.g., from stomach 306 to duodenum 310 (
In some embodiments, instead of using a difference of the mean of the first subset of recent data to the mean of the second subset of past data, the ingestible device (e.g., ingestible device 100, 300, or 400) determines whether the ratio of the mean of the first subset of recent data to the mean of the second subset of past data is greater than a predetermined threshold, “M”. In some embodiments, the predetermined threshold, “M,” will be sufficiently large to ensure that the mean of the first subset is substantially larger than the mean of the second subset, and may enable ingestible device 100 to ensure that it detected an actual transition to the duodenum. This may be particularly advantageous when the determination made at 616 is potentially unreliable due to the standard deviation of the second subset of past data being abnormally small. For example, a typical value of the predetermined threshold “M,” may be on the order of 1.2 to 2.0. It is understood any convenient type of threshold or calculation may be used to determine whether or not the first subset of data and the second subset of data are both statistically distinct from one another, and also substantially different from one another in terms of overall average value.
At 624, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data indicating a pyloric transition from the stomach to the duodenum was detected. For example ingestible device 100 may store a data flag (e.g., within memory circuitry of PCB 120 (
It will be understood that the steps and descriptions of the flowcharts of this disclosure, including

For illustrative purposes,
At 902, the ingestible device (e.g., ingestible device 100, 300, or 400) retrieves a set of reflectance levels. For example, ingestible device 100 may retrieve a data set of previously recorded reflectance levels from memory (e.g., from memory circuitry of PCB 120 (
At 904, the ingestible device (e.g., ingestible device 100, 300, or 400) includes new measurements of reflectance levels in the data set. For example, ingestible device 100 may be configured to detect a new reflectance (e.g., transmit illumination and detect the resulting reflectance using sensing sub-unit 126 (
At 906, the ingestible device (e.g., ingestible device 100, 300, or 400) obtains a first subset of recent data by applying a sliding window filter to the data set. For example, ingestible device 100 may retrieve a one-minute worth of data from the data set. If the data set includes values for reflectances measured every second, this would be approximately 60 data points worth of data. Any suitable type of window size may be used, provided that the size of the window is sufficiently large to detect peristaltic waves (e.g., fluctuations on the order of 0.1 Hz to 0.2 Hz for healthy human subjects). In some embodiments, ingestible device 100 may also clean the data, for example, by removing outliers from the first subset of data obtained through the use of the sliding window filter.
At 908, the ingestible device (e.g., ingestible device 100, 300, or 400) obtains a second subset of recent data by interpolating the first subset of recent data. For example, ingestible device 100 may interpolate the first subset of data in order to generate a second subset of data with a sufficient number of data points (e.g., data points spaced every 0.5 seconds or greater). In some embodiments, this may enable ingestible device 100 to also replace any outlier data points that may have been removed as part of applying the window filter at 906.
At 910, the ingestible device (e.g., ingestible device 100, 300, or 400) calculates a normalized frequency spectrum from the second subset of data. For example, ingestible device 100 may be configured to perform a fast Fourier transform to convert the second subset of data from a time domain representation into a frequency domain representation. It is understood that depending on the application being used, and the nature of the subset of data, any number of suitable procedures (e.g., Fourier transform procedures) may be used to determine a frequency spectrum for the second subset of data. For example, the sampling frequency and size of the second subset of data may be known in advance, and ingestible device 100 may be configured to have pre-stored values of a normalized discreet Fourier transform (DFT) matrix, or the rows of the DFT matrix corresponding to the 0.1 Hz to 0.2 Hz frequency components of interest, within memory (e.g., memory circuitry of PCB 120 (
At 912, the ingestible device (e.g., ingestible device 100, 300, or 400) determines whether at least a portion of the normalized frequency spectrum is between 0.1 Hz and 0.2 Hz above a threshold value of 0.5 Hz. Peristaltic waves in a healthy human subject occur at a rate between 0.1 Hz and 0.2 Hz, and an ingestible device experiencing peristaltic waves (e.g., ingestible device 400 detecting contractions in walls 406 of the jejunum (
At 914, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data indicating a muscle contraction was detected. For example, ingestible device 100 may store data in memory (e.g., memory circuitry of PCB 120 (
At 916, the ingestible device (e.g., ingestible device 100, 300, or 400) determines whether a total number of muscle contractions exceeds a predetermined threshold number. For example, ingestible device 100 may retrieve the total number of muscle contractions detected from memory (e.g., from memory circuitry of PCB 120 (
At 918, the ingestible device (e.g., ingestible device 100, 300, or 400) stores data indicating detection of a transition from the duodenum to the jejunum. For example, ingestible device 100 may store data in memory (e.g., from memory circuitry of PCB 120 (
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may be configured to obtain a fluid sample from the environment external to a housing of the ingestible device in response to identifying a change in the location of the ingestible device. For example, ingestible device 100 may be configured to obtain a fluid sample from the environment external to the housing of ingestible device 100 (e.g., through the use of optional opening 116 and optional rotating assembly 118 (
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may be configured to deliver a dispensable substance that is pre-stored within the ingestible device from the ingestible device into the gastrointestinal tract in response to identifying the change in the location of the ingestible device. For example, ingestible device 100 may have a dispensable substance pre-stored within the ingestible device 100 (e.g., within a storage chamber or cavity on optional storage sub-unit 118-3 (
In some embodiments, the ingestible device (e.g., ingestible device 100, 300, or 400) may be configured to perform an action based on the total number of detected muscle contractions. For example, ingestible device 100 may be configured to retrieve data indicative of the total number of muscle contractions (e.g., from memory circuitry of PCB 120 (
It will be understood that the steps and descriptions of the flowcharts of this disclosure, including
In diagram 1050, the range of frequencies 1006 between 0.1 Hz and 0.2 Hz may be the range of frequencies that ingestible device 100 searches in order to detect muscle contractions. As shown in diagram 1050, there is a strong peak in the frequency domain plot 1004 around 0.14 Hz, which is consistent with the frequency of peristaltic motion in a healthy human individual. In this case, an ingestible device 100 analyzing frequency domain plot 1004 may be configured to determine that the data is consistent with a detected muscle contraction (e.g., using a process similar to 912 of process 900 (
At 1102, around the 10-minute mark, ingestible device 100 first enters the duodenum (e.g., as determined by ingestible device 100 performing process 600 (
Flowchart 1200 represents a single sliding window process. In step 1210, the jejunum reference signal is determined based on optical reflection. Typically, this signal is as the average signal (e.g., reflected red light) over a period of time since the device was determined to enter the jejunum. The period of time can be, for example, from five minutes to 40 minutes (e.g., from 10 minutes to 30 minutes, from 15 minutes to 25 minutes). In step 1220, the detected signal (e.g., reflected red light) just after the period of time used in step 1210 is normalized to the reference signal determined in step 1210. In step 1230, the signal (e.g., reflected red light) is detected. In step 1240, the mean signal detected based on the single sliding window is compared to a signal threshold. The signal threshold in step 1240 is generally a fraction of the reference signal of the jejunum reference signal determined in step 1210. For example, the signal threshold can be from 60% to 90% (e.g., from 70% to 80%) of the jejunum reference signal. If the mean signal exceeds the signal threshold, then the process determines that the device has entered the ileum at step 1250. If the mean signal does not exceed the signal threshold, then the process returns to step 1230.
Step 1410 includes setting a first threshold in a detected signal, e.g., ratio of detected red light to detected green light, and setting a second threshold for the coefficient of variation for a detected signal, e.g., the coefficient of variation for the ratio of detected green light to detected blue light. The first threshold can be set to a fraction (e.g., from 0.5 to 0.9, from 0.6 to 0.8) of the average signal (e.g., ratio of detected red light to detected green light) in the first window, or a fraction (e.g., from 0.4 to 0.8, from 0.5 to 0.7) of the mean difference between the detected signal (e.g., ratio of detected red light to detected green light) in the two windows. The second threshold can be set to 0.1 (e.g., 0.05, 0.02).
Step 1420 includes detecting the signals in the first and second windows that are to be used for comparing to the first and second thresholds.
Step 1430 includes comparing the detected signals to the first and second thresholds. If the corresponding value is not below the first threshold or the corresponding value is not below the second threshold, then it is determined that the device has not left the ileum and entered the cecum, and the process returns to step 1420. If the corresponding value is below the first threshold and the corresponding value is below the second threshold, then it is determined that the device has left the ileum and entered the cecum, and the proceeds to step 1440.
Step 1450 includes determining whether it is the first time that that the device was determined to leave the ileum and enter the cecum. If it is the first time that the device was determined to leave the ileum and enter the cecum, then the process proceeds to step 1460. If it is not the first time that the device has left the ileum and entered the cecum, then the process proceeds to step 1470.
Step 1460 includes setting a reference signal. In this step the optical signal (e.g., ratio of detected red light to detected green light) as a reference signal.
Step 1470 includes determining whether the device may have left the cecum and returned to the ileum. The device is determined to have left the cecum and returned to the ileum if the corresponding detected signal (e.g., ratio of detected red light to detected green light) is statistically comparable to the reference signal (determined in step 1460) and the coefficient of variation for the corresponding detected signal (e.g., ratio of detected green light to detected blue light) exceeds the second threshold. If it is determined that the device may have left the cecum and returned to the ileum, the process proceeds to step 1480.
Step 1480 includes continuing to detect the relevant optical signals for a period of time (e.g., at least one minute, from five minutes to 15 minutes).
Step 1490 includes determining whether the signals determined in step 1480 indicate (using the methodology discussed in step 1470) that the device re-entered the ileum. If the signals indicate that the device re-entered the ileum, the process proceeds to step 1420. If the signals indicate that the device is in the cecum, the process proceeds to step 1492.
Step 1492 includes continuing to monitor the relevant optical signals for a period of time (e.g., at least 30 minutes, at least one hour, at least two hours).
Step 1494 includes determining whether the signals determined in step 1492 indicate (using the methodology discussed in step 1470) that the device re-entered the ileum. If the signals indicate that the device re-entered the ileum, the process proceeds to step 1420. If the signals indicate that the device is in the cecum, the process proceeds to step 1496.
At step 1496, the process determines that the device is in the cecum.
In step 1510, optical signals (e.g., the ratio of reflected red signal to reflected green signal, and reflected blue signal) are collected for a period of time (e.g., at least one minute, at least five minutes, at least 10 minutes) while the device is in the cecum (e.g., during step 1480). The average values for the recorded optical signals (e.g., the ratio of reflected red signal to reflected green signal, and reflected blue signal) establish the cecum reference signals.
In step 1520, the optical signals are detected after it has been determined that the device entered the cecum (e.g., at step 1440). The optical signals are normalized to the cecum reference signals.
Step 1530 involves determining whether the device has entered the colon. This includes determining whether any of three different criteria are satisfied. The first criterion is satisfied if the mean difference in the ratio of a detected optical signal (e.g., ratio of detected red signal to the detected green) is a multiple greater than one (e.g., 2X, 3X, 4X) the standard deviation of the corresponding signal (e.g., ratio of detected red signal to the detected green) in the second window. The second criterion is satisfied if the mean of a detected optical signal (e.g., a ratio of detected red light to detected green light) exceeds a given value (e.g., exceeds one). The third criterion is satisfied if the coefficient of variation of an optical signal (e.g., detected blue light) in the first window exceeds a given value (e.g., exceeds 0.2). If any of the three criteria are satisfied, then the process proceeds to step 1540. Otherwise, none of the three criteria are satisfied, the process returns to step 1520.

The ingestible device 1600 includes a housing 1601 that may take a shape similar to a capsule, a pill, and/or the like, which may include two ends 1602a-b. The housing 1601 may be designed to withstand the chemical and mechanical environment of the GI tract (e.g., effects of muscle contractile forces and concentrated hydrochloric acid in the stomach). A broad range of materials that may be used for the housing 1601. Examples of these materials include, but are not limited to, thermoplastics, fluoropolymers, elastomers, stainless steel and glass complying with ISO 10993 and USP Class VI specifications for biocompatibility; and any other suitable materials and combinations thereof.
In some embodiment, the wall of the housing 1601 may have a thickness of 0.5 mm-1 mm, which is sufficient to sustain an internal explosion (e.g., caused by hydrogen ignition or over pressure inside the housing).
The housing 1601 may or may not have a pH-sensitive enteric coating to detect or otherwise be sensitive to a pH level of the environment external to the ingestible device. As discussed elsewhere in the application in more detail, the ingestible device 1600 may additionally or alternatively include one more sensors, e.g., temperature sensor, optical sense.
The housing 1601 may be formed by coupling two enclosure portions together. The ingestible device 1600 may include an electronic component within the housing 1600. The electronic component may be placed proximally to an end 1602b of the housing, and includes a printed circuit board (PCB), a battery, an optical sensing unit, and/or the like.
The ingestible device 1600 further includes a gas generating cell 1603 that is configured to generate gas and thus cause an internal pressure within the housing 1601. In some embodiments, the gas generating cell may include or be connected to a separate channel or valve of the ingestible device such that gas may be release through the channel or valve to create a motion to alter the position of the ingestible device within the GI tract. Such gas release can also be used to position the ingestible device relative to the intestinal lining. In another embodiment, gas may be released through the separate channel or valve to alter the surface orientation of the intestinal tissue prior to delivery of the dispensable substance.
A traveling plunger 1604 may be placed on top of the gas generating cell 1603 within the housing 1601. The traveling plunger 1604 is a membrane that separates the gas generating cell 1603 and a storage reservoir that stores the dispensable substance 1605. In some embodiments, the traveling plunger 1604 may be a movable piston. In some embodiments, the traveling plunger 1604 may instead be a flexible membrane such as but not limited to a diaphragm. In some embodiments, the traveling plunger 1604, which may have the form of a flexible diaphragm, may be placed along an axial direction of the housing 1601, instead of being placed on top of the gas generating cell 1603. The traveling plunger or the membrane 1604 may move (when the membrane 1604 is a piston) or deform (when the membrane 1604 is a diaphragm) towards a direction of the end 1602a of the housing, when the gas generating cell 1603 generates gas to create an internal pressure that pushes the membrane 1604. In this way, the membrane or traveling plunger 1604 may push the dispensable substance 1605 out of the housing via a dispensing outlet 1607.
The housing 1601 may include a storage reservoir storing one or more dispensable substances 1605 adjacent to the traveling plunger 1604. The dispensable substance 1605 may be a therapeutic or medical agent that may take a form of a powder, a compressed powder, a fluid, a semi-liquid gel, or any other dispensable or deliverable form. The delivery of the dispensable substance 1605 may take a form such as but not limited to bolus, semi-bolus, continuous, burst drug delivery, and/or the like. In some embodiments, a single bolus is delivered proximate to the disease location. In some embodiments, more than one bolus is released at one location or more than one location. In some embodiments the release of more than one bolus is triggered according to a pre-programmed algorithm. In some embodiments the release profile is continuous. In some embodiments the release profile is time-based. In some embodiments the release profile is location-based. In some embodiments, the amount delivered is based on the severity and/or extent of the disease in the following manner. In some embodiments, the bolus is delivered in one or more of the following locations: stomach; duodenum; proximal jejunum; ileum; cecum; ascending colon; transverse colon; descending colon. In some embodiments, the IL-12/IL-23 inhibitor is ustekinumab. In some embodiments, the IL-12/IL-23 inhibitor is briakinumab. In some embodiments, the IL-12/IL-23 inhibitor is guselkumab. In some embodiments, the IL-12/IL-23 inhibitor is tildrakizumab. In some embodiments, the IL-12/IL-23 inhibitor is brazikumab. In some embodiments, the IL-12/IL-23 inhibitor is ustekinumab.
In some embodiments the dispensable substance is a small molecule therapeutic that is released in the cecum and/or other parts of the large intestine. Small molecules that are administered by typical oral routes are primarily absorbed in the small intestine, with much lower absorption taking place in the large intestine (outside of the rectum). Accordingly, an ingestible device that is capable of releasing a small molecule selectively in the large intestine (e.g., the cecum) with resulting low systemic levels (even when high doses are used) is attractive for subjects with inflammatory bowel disease in the large intestine.
In some embodiments, the storage reservoir may include multiple chambers, and each chamber stores a different dispensable substance. For example, the different dispensable substances can be released at the same time via the dispensing outlet 1607. Alternatively, the multiple chambers may take a form of different layers within the storage reservoir such that the different dispensable substance from each chamber is delivered sequentially in an order. In one example, each of the multiple chambers is controlled by a separate traveling plunger, which may be propelled by gas generation. The electronic component may control the gas generating cell 1603 to generate gas to propel a specific traveling plunger, e.g., via a separate gas generation chamber, etc., to deliver the respective substance. In some embodiments, the content of the multiple chambers may be mixed or combined prior to release, for example, to activate the drug.
The ingestible device 1600 may include a dispensing outlet 1607 at one end 1602a of the housing 1601 to direct the dispensable substance 105 out of the housing. The dispensing outlet 1607 may include an exit valve, a slit or a hole, a jet injection nozzle with a syringe, and/or the like. When the traveling plunger 1604 moves towards the end 1602a of the housing 1601, an internal pressure within the storage reservoir may increase and push the dispensing outlet to be open to let the dispensable substance 1605 be released out of the housing 1601.
In an embodiment, a pressure relief device 1606 may be placed within the housing 1601, e.g., at the end 1602a of the housing 1601.
In some embodiments, the housing 1601 may include small holes (e.g., with a diameter smaller than 2 mm), e.g., on the side of the housing 1601, or at the end 1602a to facilitate loading the dispensable substance into the storage reservoir.
In some embodiments, a feedback control circuit (e.g., a feedback resistor, etc.) may be added to send feedback from the gas generating cell 1603 to the electronic component such that when the internal pressure reaches a threshold level, the electronic component may control the gas generating cell 1603 to turn off gas generation, or to activate other safety mechanism (e.g., feedback-controlled release valve, etc.). For example, an internal pressure sensor may be used to measure the internal pressure within the ingestible device and generate feedback to the feedback control circuit.
In some embodiments, based on the elution rate of gas from the cell, and an internal volume of the ingestible device, it may take time to generate sufficient gas 1611 to deliver the substance 1605, and the time required may be 30 seconds or longer. For example, the time to generate a volume of hydrogen equivalent to 500 μL of fluid would be approximately 5 minutes. A longer period of time may be needed based upon non-ideal conditions within the ingestible device, such as friction, etc. Thus, given that the production of gas (e.g., hydrogen) may take time, gas generation may need to start prior to the ingestible device arriving at the site of delivery to build pressure up within the device. The ingestible device may then need to know when it is approaching the site of delivery. For example, the device may start producing gas on an “entry transition,” which is determined by temperature, so as to produce enough gas to be close to the pressure high enough to deliver the dispensable substance. The ingestible device may then only start producing gas again when it arrives at the site of delivery, which will cause the internal pressure within the ingestible device to reach a level required by the dispensing outlet to release the dispensable substance. Also, for regio-specific delivery, the ingestible device may estimate the time it takes to build up enough pressure to deliver the dispensable substance before the ingestible device arrives at a specific location, to activate gas generation.
For example, for systemic delivery, when an internal volume of the ingestible device is around 500 μL, a gas generation time of 2 hours, an initial pressure of approximately 300 pound per square inch absolute (psia) may be generated, with higher and lower pressures possible. The generated pressure may drop when air enters the storage reservoir which was previously occupied by the dispensable substance during the dispensing process. For systemic drug delivery, a force with a generated pressure of approximately 100 to 360 pound per square inch (psi) may be required for dermal penetration, e.g., to penetrate the mucosa or epithelial layer. The pressure may also vary depending on the nozzle design at the dispensing outlet, fluid viscosity, and surrounding tissue proximity and properties.
The gas 1611 that may be generated for a continuous delivery of drug (e.g., 1 cc H2 in 4 hours, 16 breaths per minute at 0.5 L tidal volume) may equate to 1 cc hydrogen in approximately 2000 L of exhaled air, or approximately 0.5 ppm H2, which is below physiologic values of exhaled hydrogen. Reducing this time to 10 minutes equates to approximately 13 ppm hydrogen. Thus, due to the length of intestine that may be covered during this time period, the ingestible device may possess a higher localized value than physiologic.
The battery cells 1631 may have a height of 1.65 mm each, and one to three batteries may be used. The height of the piston may be reduced with custom molded part for around 1.5 mm to save space. If the gas generating cell 1603 is integrated with the piston 1634, the overall height of the PCB, batteries and gas generating cell in total can be reduced to around 5 mm, thus providing more space for drug storage. For example, for an ingestible device of 7.8 mm in length (e.g., from end 1602a to the other end 1602b), a reservoir compartment 1635 or a storage reservoir 1661 of approximately 6004, may be used for drug delivery. For another example, for an ingestible device of 17.5 mm in length, a reservoir compartment 1635 or a storage reservoir 1661 of approximately 13004, may be used for drug release.
In some implementations, at the reservoir 1635 or 1661 for storing a therapeutically effective amount of the IL-12/IL-23 inhibitor forms at least a portion of the device housing 1601. The therapeutically effective amount of the IL-12/IL-23 inhibitor can be stored in the reservoir 1635 or 1661 at a particular pressure, for example, determined to be higher than a pressure inside the GI tract so that once the reservoir 1635 or 1661 is in fluid communication with the GI tract, the IL-12/IL-23 inhibitor is automatically released. In certain implementations, the reservoir compartment 1635 includes a plurality of chambers, and each of the plurality of the chambers stores a different dispensable substance or a different storage reservoir 1661.
In certain embodiments, the storage reservoir 1661 is a compressible component or has compressible side walls. In particular embodiments, the compressible component can be composed, at least in part, or coated (e.g., internally) with polyvinyl chloride (PVC), silicone, DEHP (di-2-ethylhexyl phthalate), Tyvek, polyester film, polyolefin, polyethylene, polyurethane, or other materials that inhibit the IL-12/IL-23 inhibitor from sticking to the reservoir and provide a sterile reservoir environment for the IL-12/IL-23 inhibitor. The storage reservoir 1661 can be hermetically sealed. The reservoir compartment 1635 or storage reservoir 1661 can be configured to store IL-12/IL-23 inhibitor in quantities in the range of 0.01 mL-2 mL, such as 0.05 mL-2 mL, such as 0.05 mL-2 mL, such as 0.6 mL-2 mL. In some embodiments, the storage reservoir 1661 is attachable to the device housing 1601, for example, in the reservoir compartment. Accordingly, the storage reservoir 1635 can be loaded with the IL-12/IL-23 inhibitor prior to being positioned in and/or coupled to the ingestible device housing 1601. The ingestible device housing 1601 includes one or more openings configured as a loading port to load the dispensable substance into the reservoir compartment. In another embodiment, the ingestible device housing 1601 includes one or more openings configured as a vent.
As noted above, in some embodiments, a storage reservoir (optionally, containing an IL-12/IL-23 inhibitor, such as a therapeutically effective amount of IL-12/IL-23 inhibitor) is attachable to an ingestible device. In general, in such embodiments the storage reservoir and ingestible device can be designed in any appropriate fashion so that the storage reservoir can attach to the ingestible device when desired. Examples of designs include a storage reservoir that fits entirely within the ingestible device (e.g., in the ingestible device so that the storage reservoir is sealed within the device at the time the device is ingested by a subject), a storage reservoir that fits partially within the ingestible device, and a storage reservoir that is carried by the housing of the device. In some embodiments, the storage reservoir snap fits with the ingestible device. In certain embodiments, the storage reservoir is friction fit with the ingestible device. In some embodiments, the storage reservoir is held together with the ingestible device via a biasing mechanism, such as one or more springs, one or more latches, one or more hooks, one or more magnets, and/or electromagnetic radiation. In certain embodiments, the storage reservoir can be a pierceable member. In some embodiments, the ingestible device has a sleeve into which the storage reservoir securely fits. In some embodiments, the storage reservoir is disposed in/on a slidable track/groove so that it can move onto a piercing needle when delivery of the therapeutic agent is desired. In certain embodiments, the storage reservoir is made of a soft plastic coating, which is contacted with a needle at any orientation to deliver the therapeutic agent when desired. Generally, the storage reservoir can be made of one or more appropriate materials, such as, for example, one or more plastics and/or one or more metals or alloys. Exemplary materials include silicone, polyvinyl chloride, polycarbonate and stainless steel. Optionally, the design may be such that the storage reservoir carries some or all of the electrical componentry to be used by the ingestible device. Although the foregoing discussion relates to one storage reservoir, it is to be understood that an ingestible device can be designed to carry any desired number (e.g., two, three, four, five) storage reservoirs. Different storage reservoirs can have the same or different designs. In some embodiments, the ingestible device (when fully assembled and packaged) satisfies the regulatory requirements for marketing a medical device in one or more jurisdictions selected from the United States of America, the European Union or any member state thereof, Japan, China, Brazil, Canada, Mexico, Colombia, Argentina, Chile, Peru, Russia, the UK, Switzerland, Norway, Turkey, Israel, any member state of the Gulf Cooperative Council, South Africa, India, Australia, New Zealand, South Korea, Singapore, Thailand, the Philippines, Malaysia, Viet Nam, and Indonesia, Taiwan and Hong Kong.
In certain embodiments, the ingestible device housing 1601 includes one or more actuation systems (e.g., gas generating cell 1603) for pumping the IL-12/IL-23 inhibitor from the reservoir 1635. In some embodiments, the actuation system can include a mechanical, electrical, electromechanical, hydraulic, and/or fluid actuation system. For example, a chemical actuation means may use chemical reaction of mixing one or more reagents to generate a sufficient volume of gas to propel the piston or drive element 1634 for drug release. The actuation system can be integrated into the reservoir compartment 1635 or can be an auxiliary system acting on or outside of the reservoir compartment 1635. For example, the actuation system can include pumping system for pushing/pulling the IL-12/IL-23 inhibitor out of the reservoir compartment 1635 or the actuation system can be configured to cause the reservoir compartment 1635 to change structurally so that the volume inside of the reservoir compartment 1635 changes, thereby dispensing the IL-12/IL-23 inhibitor from the reservoir compartment 1635. The actuation system can include an energy storage component such as a battery or a capacitor for powering the actuation system. The actuation system can be actuated via gas pressure or a system storing potential energy, such as energy from an elastic reservoir component being expanded during loading of the reservoir and after being positioned in the ingestible device housing 1601 being subsequently released from the expanded state when the ingestible device housing is at the location for release within the GI tract. In certain embodiments, the reservoir compartment 1635 can include a membrane portion, whereby the IL-12/IL-23 inhibitor is dispensed from the reservoir compartment 1635 or storage reservoir 1661 via osmotic pressure.
In particular embodiments the storage reservoir 1661 is in a form of a bellow that is configured to be compressed via a pressure from the gas generating cell. The IL-12/IL-23 inhibitor may be loaded into the bellow, which may be compressed by gas generation from the gas generating cell or other actuation means to dispense the dispensable substance through the dispensing outlet 1607 and out of the housing 1601. In some embodiments, the ingestible device includes a capillary plate placed between the gas generating cell and the first end of the housing, and a wax seal between the gas generating cell and the reservoir, wherein the wax seal is configured to melt and the dispensable substance is pushed through the capillary plate by a pressure from the gas generating cell. The shape of the bellow may aid in controlled delivery. The reservoir compartment 1635 includes a dispensing outlet, such as a valve or dome slit 1662 extending out of an end of the housing 1601, in accordance with particular implementations. Thus when the bellow is being compressed, the dispensable substance may be propelled out of the bellow through the valve or the dome slit.
In certain embodiments, the reservoir compartment 1635 includes one or more valves (e.g., a valve in the dispensing outlet 1607) that are configured to move or open to fluidly couple the reservoir compartment 1635 to the GI tract. In certain embodiments, a housing wall of the housing 1601 can form a portion of the reservoir compartment 1635. In certain embodiments, the housing walls of the reservoir serve as a gasket. One or more of the one or more valves are positioned in the housing wall of the device housing 1601, in accordance with particular implementations. One or more conduits may extend from the reservoir 1635 to the one or more valves, in certain implementations.
In certain embodiments, a housing wall of the housing 1601 can be formed of a material that is configured to dissolve, for example, in response to contact at the disease site. In certain embodiments, a housing wall of the housing 1601 can be configured to dissolve in response to a chemical reaction or an electrical signal. The one or more valves and/or the signals for causing the housing wall of the housing 1601 to dissolve or dissipate can be controlled by one or more processors or controllers positioned on PCB 1632 in the device housing 1601. The controller is communicably coupled to one or more sensors or detectors configured to determine when the device housing 1601 is proximate to a disease site. The sensors or detectors comprise a plurality of electrodes comprising a coating, in certain implementations. Releasing of the IL-12/IL-23 inhibitor from the reservoir compartment 1635 is triggered by an electric signal from the electrodes resulting from the interaction of the coating with the one or more sites of disease site. The one or more sensors can include a chemical sensor, an electrical sensor, an optical sensor, an electromagnetic sensor, a light sensor, and/or a radiofrequency sensor. In particular embodiments, the device housing 1601 can include one or more pumps configured to pump the therapeutically effective amount of the IL-12/IL-23 inhibitor from the reservoir compartment 1635. The pump is communicably coupled to the one or more controllers. The controller is configured to activate the pump in response to detection by the one or more detectors of the disease site and activation of the valves to allow the reservoir 1635 to be in fluid communication with the GI tract. The pump can include a fluid actuated pump, an electrical pump, or a mechanical pump.
In certain embodiments, the device housing 1601 comprises one or more anchor systems for anchoring the device housing 1601 or a portion thereof at a particular location in the GI tract adjacent the disease site. In some embodiments, a storage reservoir comprises an anchor system, and the storage reservoir comprising a releasable substance is anchored to the GI tract. The anchor system can be activated by the controller in response to detection by the one or more detectors of the disease site. In certain implementations, the anchor system includes legs or spikes configured to extend from the housing wall(s) of the device housing 1601. The spikes can be configured to retract and/or can be configured to dissolve over time. An example of an attachable device that becomes fixed to the interior surface of the GI tract is described in PCT Patent Application PCT/US2015/012209, “Gastrointestinal Sensor Implantation System,” filed Jan. 21, 2015, which is hereby incorporated by reference herein in its entirety.
In some embodiments, an ingestible device can have an umbrella-shaped exit valve structure as a dispensing outlet of the ingestible device. Optionally, an ingestible device can have a flexible diaphragm to deform for drug delivery, and/or an integrated piston and gas generating cell such that the gas generating cell is movable with the piston to push for drug delivery.
In certain embodiments, an ingestible device can be anchored within the intestine by extending hooks from the ingestible device after it has entered the region of interest. For example, when the ingestible device determines it has arrived at a location within the GI tract, the hooks can be actuated to extend outside of the ingestible device to catch in the intestinal wall and hold the ingestible device in the respective location. In some embodiments, the hook can pierce into the intestinal wall to hold the ingestible device 100 in place. The hooks can be hollow. A hollow hook can be used to anchor the ingestible device and/or to dispense a substance from the dispensable substance, e.g., into the intestinal wall.
In some embodiments an ingestible device includes an intestinal gripper to grip a portion of the intestinal wall for delivering the dispensable substance. Such a gripper can include two or more arms configured to out of the device and close to grip a portion of the intestinal wall.
An injecting needle can be used with the anchoring arms to inject dispensable substance into the intestinal wall after a portion of the intestinal wall is gripped.
In some embodiments, when the gas generating cell generates gas to propel the piston to move towards the nozzle such that the dispensable substance can be pushed under the pressure to break a burst disc to be injected via the nozzle.
In some embodiments, an ingestible device has a jet delivery mechanism with enhanced usable volume of dispensable substance. For example, the nozzle may be placed at the center of the ingestible device, and gas channels may be placed longitudinally along the wall of the ingestible device to transport gas from the gas generating cell to propel the piston, which is placed at an end of the ingestible device.
In some embodiments, the ingestible device can use osmotic pressure to adhere a suction device of the ingestible device to the intestinal wall. For example, the ingestible device may have an osmotic mechanism that has a chamber storing salt crystals. The chamber can include a mesh placed in proximate to a burst valve at one end of the chamber, and a reverse osmosis (RO) membrane placed in proximate to a valve on the other end of the chamber. A suction device, e.g., two or more suction fingers, is placed outside of the chamber with an open outlet exposed to luminal fluid in the GI tract. When the osmotic mechanism is inactivated, e.g., the valve is closed so that no luminal fluid is drawn into the osmotic chamber. When the osmotic mechanism is activated by opening the valve, luminal fluid enters the ingestible device through an outlet of the suction device and enters the osmotic chamber through the valve. The salt in the chamber is then dissolved into the fluid. The RO membrane prevents any fluid to flow in the reverse direction, e.g., from inside the chamber to the valve. The fluid continues to flow until all the salt contained in the chamber is dissolved or until intestinal tissue is drawn into the suction device. As luminal fluid keeps flowing into the chamber, the solution of the luminal fluid with dissolved salt in the chamber may reduce osmotic pressure such that the suction force at may also be reduced. In this way, suction of the intestinal tissue may stall before the tissue is in contact with the valve to avoid damage to the intestinal tissue.
An ingestible device employing an osmotic mechanism can also include a suction device as illustrated. The suction device can be two or more suction fingers 347a-b disposed proximate to the outlet. The outlet can be connected to a storage reservoir storing the dispensable substance (e.g., therapeutic agent). The storage reservoir can contact a piston (similar to 104 in
In some embodiments, tumbling suction by an ingestible device is used. Such an ingestible device does not require any electronics or other actuation elements. Such an ingestible device may constantly, intermittently, or periodically tumble when travelling through the intestine. When the ingestible device tumbles to a position that the outlet is in direct contact with the intestinal wall, a suction process similar to that described in the preceding paragraph may occur. Additional structural elements such as fins, flutes or the like may be added to the outer wall of the ingestible device 100 to promote the tumbling motion.
In certain embodiments, the reservoir is an anchorable reservoir, which is a reservoir comprising one or more anchor systems for anchoring the reservoir at a particular location in the GI tract adjacent the disease site. In certain embodiments, the anchor system includes legs or spikes or other securing means such as a piercing element, a gripping element, a magnetic-flux-guiding element, or an adhesive material, configured to extend from the anchorable reservoir of the device housing. The spikes can be configured to retract and/or can be configured to dissolve over time. In some embodiments, the anchorable reservoir is suitable for localizing, positioning and/or anchoring. In some embodiments, the anchorable reservoir is suitable for localizing, and positioning and/or anchoring by an endoscope. In some embodiments, the anchorable reservoir is connected to the endoscope. In some embodiments, the anchorable reservoir is connected to the endoscope in a manner suitable for oral administration. In some embodiments, the anchorable reservoir is connected to the endoscope in a manner suitable for rectal administration. Accordingly, provided herein in some embodiments is an anchorable reservoir is connected to an endoscope wherein the anchorable reservoir comprises a therapeutically effective amount of the IL-12/IL-23 inhibitor. In some embodiments the endoscope is fitted with a spray catheter.
Exemplary embodiments of anchorable reservoirs are as follows. In more particular examples of the following exemplary embodiments the reservoir is connected to an endoscope.
In one embodiment, the anchorable reservoir comprises an implant capsule for insertion into a body canal to apply radiation treatment to a selected portion of the body canal. The reservoir includes a body member defining at least one therapeutic treatment material receiving chamber and at least one resilient arm member associated with the body member for removably engaging the body canal when the device is positioned therein.
In one embodiment the anchorable reservoir has multiple suction ports and permits multiple folds of tissue to be captured in the suction ports with a single positioning of the device and attached together by a tissue securement mechanism such as a suture, staple or other form of tissue bonding. The suction ports may be arranged in a variety of configurations on the reservoir to best suit the desired resulting tissue orientation.
In some embodiments an anchorable reservoir comprises a tract stimulator and/or monitor IMD comprising a housing enclosing electrical stimulation and/or monitoring circuitry and a power source and an elongated flexible member extending from the housing to an active fixation mechanism adapted to be fixed into the GI tract wall is disclosed. After fixation is effected, the elongated flexible member bends into a preformed shape that presses the housing against the mucosa so that forces that would tend to dislodge the fixation mechanism are minimized. The IMD is fitted into an esophageal catheter lumen with the fixation mechanism aimed toward the catheter distal end opening whereby the bend in the flexible member is straightened. The catheter body is inserted through the esophagus into the GI tract cavity to direct the catheter distal end to the site of implantation and fix the fixation mechanism to the GI tract wall. The IMD is ejected from the lumen, and the flexible member assumes its bent configuration and lodges the hermetically sealed housing against the mucosa. A first stimulation/sense electrode is preferably an exposed conductive portion of the housing that is aligned with the bend of the flexible member so that it is pressed against the mucosa. A second stimulation/sense electrode is located at the fixation site.
In some embodiments a reservoir for sensing one or more parameters of a patient is anchored to a tissue at a specific site and is released from a device, using a single actuator operated during a single motion. As an example, a delivery device may anchor the capsule to the tissue site and release the reservoir from the delivery device during a single motion of the actuator.
In some embodiments a device is provided comprising: a reservoir configured to contain a fluid, the reservoir having at least one outlet through which the fluid may exit the reservoir; a fluid contained within the reservoir; a primary material contained within the reservoir and having a controllable effective concentration in the fluid; and at least one electromagnetically responsive control element located in the reservoir or in a wall of the reservoir and adapted for modifying the distribution of the primary material between a first active form carried in the fluid and a second form within the reservoir in response to an incident electromagnetic control signal, the effective concentration being the concentration of the first active form in the fluid, whereby fluid exiting the reservoir carries the primary material in the first active form at the effective concentration.
In some embodiments systems and methods are provided for implementing or deploying medical or veterinary devices or reservoirs (a) operable for anchoring at least partly within a digestive tract, (b) small enough to pass through the tract per vias naturales and including a wireless-control component, (c) having one or more protrusions positionable adjacent to a mucous membrane, (d) configured to facilitate redundant modes of anchoring, (e) facilitating a “primary” material supply deployable within a stomach for an extended and/or controllable period, (f) anchored by one or more adaptable extender modules supported by a subject's head or neck, and/or (g) configured to facilitate supporting at least a sensor within a subject's body lumen for up to a day or more.
In certain embodiments, the reservoir is attachable to an ingestible device. In certain embodiments, the ingestible device comprises a housing and the reservoir is attachable to the housing. In certain embodiments, the attachable reservoir is also an anchorable reservoir, such as an anchorable reservoir comprising one or more anchor systems for anchoring the reservoir at a particular location in the GI tract as disclosed hereinabove.
Accordingly, in certain embodiments, provided herein is an IL-12/IL-23 inhibitor for use in a method of treating a disease of the gastrointestinal tract as disclosed herein, wherein the IL-12/IL-23 inhibitor is contained in a reservoir suitable for attachment to a device housing, and wherein the method comprises attaching the reservoir to the device housing to form the ingestible device, prior to orally administering the ingestible device to the subject.
In certain embodiments, provided herein is an attachable reservoir containing an IL-12/IL-23 inhibitor for use in a method of treating a disease of the gastrointestinal tract, wherein the method comprises attaching the reservoir to a device housing to form an ingestible device and orally administering the ingestible device to a subject, wherein the IL-12/IL-23 inhibitor is released by device at a location in the gastrointestinal tract of the subject that is proximate to one or more sites of disease.
In certain embodiments, provided herein is an attachable reservoir containing an IL-12/IL-23 inhibitor, wherein the reservoir is attachable to a device housing to form an ingestible device that is suitable for oral administration to a subject and that is capable of releasing the IL-12/IL-23 inhibitor at a location in the gastrointestinal tract of the subject that is proximate to one or more sites of disease.
In particular implementation the ingestible device includes cameras (e.g., video cameras) that affords inspection of the entire GI tract without discomfort or the need for sedation, thus avoiding many of the potential risks of conventional endoscopy. Video imaging can be used to help determine one or more characteristics of the GI tract, including the location of disease (e.g., presence or location of inflamed tissue and/or lesions associated with inflammatory bowel disease). In some embodiments, the ingestible device 101 may comprise a camera for generating video imaging data of the GI tract which can be used to determine, among other things, the location of the device. Examples of video imaging capsules include Medtronic's PillCam™, Olympus' Endocapsule®, and IntroMedic's MicroCam™. For a review of imaging capsules, see Basar et al., “Ingestible Wireless Capsule Technology: A Review of Development and Future Indication,” International Journal of Antennas and Propagation (2012):1-14). Other imaging technologies implemented with the device 101 can include thermal imaging cameras, and those that employ ultrasound or Doppler principles to generate different images (see Chinese patent application CN104473611: “Capsule endoscope system having ultrasonic positioning function.”
Ingestible devices can be equipped with sources for generating reflected light, including light in the Ultraviolet, Visible, Near-infrared and/or Mid-infrared spectrum, and the corresponding detectors for spectroscopy and hyperspectral imaging. Likewise, autofluorescence may be used to characterize GI tissue (e.g., subsurface vessel information), or low-dose radiation (see Check-Cap™) can be used to obtain 3D reconstructed images.
An ingestible device in accordance with particular embodiments of the present disclosure may comprise a component made of a non-digestible material and contain the IL-12/IL-23 inhibitor. In some embodiments, the material is plastic.
It is envisaged that the device is single-use. The device is loaded with a drug prior to the time of administration. In some embodiments, it may be preferred that there is provided a medicinal product comprising the device pre-filled with the drug.
Several systems may actively actuate and control the capsule position and orientation in different sections of the GI tract. Examples include leg-like or anchor-like mechanisms that can be deployed by an ingestible device to resist peristaltic forces in narrowed sections of the GI tract, such as the intestine, and anchor the device to a location. Other systems employ magnetic shields of different shapes that can interact with external magnetic fields to move the device. These mechanisms may be particularly useful in areas outside of the small intestine, like the cecum and large intestine.
An anchoring mechanism may be a mechanical mechanism. For example, a device may be a capsule comprising a plurality of legs configured to steer the capsule. The number of legs in the capsule may be, for example, two, four, six, eight, ten or twelve. The aperture between the legs of the device may be up to about 35 mm; about 30 to about 35 mm; about 35 to about 75 mm; or about 70 to about 75 mm. The contact area of each leg may be varied to reduce impact on the tissue. One or more motors in the capsule may each actuate a set of legs independently from the other. The motors may be battery-powered motors.
An anchoring mechanism may be a non-mechanical mechanism. For example, a device may be a capsule comprising a permanent magnet located inside the capsule. The capsule may be anchored at the desired location of the GI tract by an external magnetic field.
An anchoring mechanism may comprise a non-mechanical mechanism and a mechanical mechanism. For example, a device may be a capsule comprising one or more legs, one or more of which are coated with an adhesive material.
Ingestible devices can be active or passive, depending on whether they have controlled or non-controlled locomotion. Passive (non-controlled) locomotion is more commonly used among ingestible devices given the challenges of implementing a locomotion module. Active (controlled) locomotion is more common in endoscopic ingestible capsules. For example, a capsule may comprise a miniaturized locomotion system (internal locomotion). Internal locomotion mechanisms may employ independent miniaturized propellers actuated by DC brushed motors, or the use of water jets. As an example, a mechanism may comprise flagellar or flap-based swimming mechanisms. As an example, a mechanism may comprise cyclic compression/extension shape-memory alloy (SMA) spring actuators and anchoring systems based on directional micro-needles. As an example, a mechanism may comprise six SMA actuated units, each provided with two SMA actuators for enabling bidirectional motion. As an example, a mechanism may comprise a motor adapted to electrically stimulating the GI muscles to generate a temporary restriction in the bowel.
As an example, a capsule may comprise a magnet and motion of the capsule is caused by an external magnetic field. For example, a locomotion system may comprise an ingestible capsule and an external magnetic field source. For example, the system may comprise an ingestible capsule and magnetic guidance equipment such as, for example, magnetic resonance imaging and computer tomography, coupled to a dedicated control interface.
In some embodiments drug release mechanisms may also be triggered by an external condition, such as temperature, pH, movement, acoustics, or combinations thereof.
In some embodiments, an endoscope or ingestible device is used in biopsy and/or surgery. Ingestible devices may comprise a mechanism adapted to permit the collection of tissue samples. In some examples, this is achieved using electro-mechanical solutions to collect and store the sample inside an ingestible device. As an example, a biopsy mechanism may include a rotational tissue cutting razor fixed to a torsional spring or the use of microgrippers to fold and collect small biopsies. As an example, Over-the-scope clips (OTSC®) may be used to perform endoscopic surgery and/or biopsy. As an example of the methods disclosed herein, the method may comprise releasing an IL-12/IL-23 inhibitor and collecting a sample inside the device. As an example, the method may comprise releasing an IL-12/IL-23 inhibitor and collecting a sample inside the device in a single procedure.
The overall shape of the ingestible device 2100, or any of the other ingestible devices discussed in this disclosure, may be similar to an elongated pill or capsule.
In some embodiments, a portion of the curved chamber 2110 may be used as a sampling chamber, which may hold samples obtained from the GI tract. In some embodiments the curved chamber 2110 is subdivided into sub-chambers, each of which may be separated by a series of one or more valves or interlocks.
In some embodiments, the first opening 2106, the second opening 2108, or the curved chamber 2110 include one or more of a hydrophilic or hydrophobic material, a sponge, a valve, or an air permeable membrane.
The use of a hydrophilic material or sponge may allow samples to be retained within the curved chamber 2110, and may reduce the amount of pressure needed for fluid to enter through the first opening 2106 and dislodge air or gas in the curved chamber 2110. Examples of hydrophilic materials that may be incorporated into the ingestible device 2100 include hydrophilic polymers such as polyvinyl alcohol, polyvinyl pyrrolidone, and the like. Similarly, materials that have undergone various types of treatments, such as plasma treatments, may have suitable hydrophilic properties, and may be incorporated into the investible device 2100. Sponges may be made of any suitable material or combination of materials, such as fibers of cotton, rayon, glass, polyester, polyethylene, polyurethane, and the like. Sponges generally may be made from commercially available materials, such as those produced by Porex®.
As discussed in more detail below, in some embodiments, the sponges may be treated in order to change their absorbency or to help preserve samples.
In some embodiments, the sponges may be cut or abraded to change their absorbency or other physical properties.
Hydrophobic materials located near the second opening 2108 may repel liquids, discouraging liquid samples from entering or exiting the curved chamber 2110 through the second opening 2108. This may serve a similar function as an air permeable membrane. Examples of hydrophobic materials which may be incorporated into the ingestible device 2100 include polycarbonate, acrylics, fluorocarbons, styrenes, certain forms of vinyl, stainless steel, silicone, and the like.
The various materials listed above are provided as examples, and are not limiting. In practice, any type of suitable hydrophilic, hydrophobic, or sample preserving material may be used in the ingestible device 2100.
In some embodiments, an ingestible device includes a moveable valve as a diaphragm valve, which uses a mechanical actuator to move a flexible diaphragm in order to seal or unseal an aperture in a second portion of an inlet region, which may effectively block or unblock the inlet region. However, it will be understood that, in some embodiments, the moveable valve may be a different type of valve. For example, in some embodiments the moveable valve may be replaced by a pumping mechanism. As another example, in some embodiments the moveable valve is replaced with an osmotic valve
A sampling chamber of an ingestible device can have an exit port to allow air or gas to exit the sampling chamber, while preventing at least a portion of the sample obtained by the ingestible device from exiting the sampling chamber. For example, the exit port may include a gas-permeable membrane. An ingestible device can include one-way valve as part of its exit port.
An ingestible device can include an outlet port connected to the volume within housing of the ingestible device. The outlet port may provide a path for the gas to exit the ingestible device and be released into the environment surrounding the ingestible device. This may prevent pressure from building up within the housing of the ingestible device. In some embodiments, an ingestible device does not include an outlet port, and the gas stays inside the volume of the ingestible device. In some embodiments, the outlet port may contain a gas permeable membrane, a one-way valve, a hydrophobic channel, or some other mechanism to avoid unwanted material, (e.g., fluids and solid particulates from within the GI tract), from entering the ingestible device through the outlet port.
In some embodiments, the ingestible device may include a sensor within or proximate to the sampling chamber. For example, this sensor may be used to detect various properties of a sample contained within the sampling chamber, or this sensor may be used to detect the results of an assay technique applied to the sample contained within the sampling chamber.
In some embodiments, a hydrophilic sponge is located within the sampling chamber, and the hydrophilic sponge may be configured to absorb the sample as the sample enters the sampling chamber. In some embodiments, the hydrophilic sponge fills a substantial portion of the sampling chamber, and holds the sample for an extended period of time. This may be particularly advantageous if the sample is collected from the ingestible device after the ingestible device exits the body. In some embodiments, the hydrophilic sponge is placed on only certain surfaces or fills only certain portions of the sampling chamber. For example, it may be possible to line certain walls (or all walls) of the sampling chamber with a hydrophilic sponge to assist in drawing in the sample, while leaving some (or none) of the walls of the sampling chamber uncovered. Leaving walls uncovered may allow the use of diagnostics or assay techniques that require a relatively un-obscured optical path.
In some embodiments, the ingestible device may include a sealed vacuum chamber connected to the exit port, or connected directly or indirectly to the sampling chamber. In some embodiments a pin valve may be used as a moveable valve (e.g., as moveable valve of ingestible device). In certain embodiments, a rotary valve may be used as a moveable valve (e.g., as moveable valve of ingestible device). In some embodiments, a flexible diaphragm, or diaphragm valve, may be used as a moveable valve (e.g., as moveable valve of ingestible device). In certain embodiments, a mechanism is near the diaphragm or in direct contact with the diaphragm. The spring mechanism may apply pressure to the diaphragm to oppose the pressure applied by the mechanical actuator, which may cause the flexible diaphragm to be moved into an open position when the mechanical actuator is not applying pressure to the flexible diaphragm. Additionally, this may ensure that the diaphragm valve remains open when the mechanical actuator is not applying pressure across the flexible diaphragm. In some embodiments, moving the mechanical actuator from a closed position to an open position causes a volume of the inlet region within the ingestible device to increase. This may cause the pressure within the inlet region to be reduced, generating suction to draw a sample into the inlet region. Similarly, moving the mechanical actuator from an open position to a closed position may cause the volume of the inlet region to be reduced. This may cause the pressure within the inlet region to be increased, pushing the sample out of the inlet region. Depending on the design of the inlet region, the mechanical actuator, and the moveable valve, this may push the sample into the sampling chamber rather than pushing the sample back through the opening in the ingestible device.
While the foregoing description is made with regard to a valve system having one open position and one closed position (e.g., a two-stage valve system), the disclosure is not limited in this sense. Rather, the concepts described above with regard to a two stage valve system can be implemented with a valve system have more than two stages (e.g., three stages, four stages, five stages, etc.).
As noted above in addition to a valve system, an ingestible device includes a sampling system.
Some or all of the sponges of the above-described sampling systems may contain one or more preservatives (see discussion above). Typically, the assay sponge and/or the volume sponge 3230 and/or the transfer sponge contain one or more preservatives. Typically, the preservative(s) are selected based on the analyte of interest, e.g., an analyte (such as a protein biomarker) for a GI disorder.
An ingestible device may be equipped with a communication system adapted to transmit and/or receive data, including imaging and/or localization data. As an example, a communication system may employ radiofrequency transmission. Ingestible devices using radiofrequency communication are attractive because of their efficient transmission through the layers of the skin. This is especially true for low frequency transmission (UHF-433 ISM and lower, including the Medical Device Radio Communication Service band (MDRS) band 402-406 MHz). In another embodiment, acoustics are used for communications, including the transmission of data. For example, an ingestible capsule may be able to transmit information by applying one or more base voltages to an electromechanical transducer or piezoelectric (e.g., PZT, PVDF, etc.) device to cause the piezoelectric device to ring at particular frequencies, resulting in an acoustic transmission. A multi-sensor array for receiving the acoustic transmission may include a plurality of acoustic transducers that receive the acoustic transmission from a movable device such as an ingestible capsule as described in U.S. patent application Ser. No. 11/851,214 filed Sep. 6, 2007, incorporated by reference herein in its entirety.
As an example, a communication system may employ human body communication technology. Human body communication technology uses the human body as a conductive medium, which generally requires a large number of sensor electrodes on the skin. As an example, a communication system may integrate a data storage system.
In some embodiments the device may comprise environmental sensors to measure pH, temperature, transit times, or combinations thereof. Other examples of environmental sensors include, but are not limited to a capacitance sensor, an impedance sensor, a heart rate sensor, acoustic sensor such as a microphone or hydrophone, image sensor, and/or a movement sensor. In one embodiment, the ingestible device comprises a plurality of different environmental sensors for generating different kinds of environmental data.
In order to avoid the problem of capsule retention, a thorough past medical and surgical history should be undertaken. In addition, several other steps have been proposed, including performing investigations such as barium follow-through. In cases where it is suspected that there is a high risk of retention, the patient is given a patency capsule a few days before swallowing an ingestible device. Any dissolvable non-endoscopic capsule may be used to determine the patency of the GI tract. The patency capsule is usually the same size as the ingestible device and can be made of cellophane. In some embodiments, the patency capsule contains a mixture of barium and lactose, which allows visualization by x-ray. The patency capsule may also include a radiotag or other label, which allows for it to be detected by radio-scanner externally. The patency capsule may comprise wax plugs, which allow for intestinal fluid to enter and dissolve the content, thereby dividing the capsule into small particles.
Accordingly, in some embodiments, the methods herein comprise (a) identifying a subject having a disease of the gastrointestinal tract and (b) evaluating the subject for suitability to treatment. In some embodiments, the methods herein comprise evaluating for suitability to treatment a subject identified as having a disease of the gastrointestinal tract. In some embodiments, evaluating the subject for suitability to treatment comprises determining the patency of the subject's GI tract.
In some embodiments, an ingestible device comprises a tissue anchoring mechanism for anchoring the ingestible device to a subject's tissue. For example, an ingestible device could be administered to a subject and once it reaches the desired location, the tissue attachment mechanism can be activated or deployed such that the ingestible device, or a portion thereof, is anchored to the desired location. In some embodiments, the tissue anchoring mechanism is reversible such that after initial anchoring, the tissue attachment device is retracted, dissolved, detached, inactivated or otherwise rendered incapable of anchoring the ingestible device to the subject's tissue. In some embodiments the attachment mechanism is placed endoscopically.
In some embodiments, a tissue anchoring mechanism comprises an osmotically-driven sucker. In some embodiments, the osmotically-driven sucker comprises a first valve on the near side of the osmotically-driven sucker (e.g., near the subject's tissue) and a second one-way valve that is opened by osmotic pressure on the far side of the osmotically-driven sucker, and an internal osmotic pump system comprising salt crystals and semi-permeable membranes positioned between the two valves. In such embodiments, osmotic pressure is used to adhere the ingestible device to the subject's tissue without generating a vacuum within the ingestible capsule. After the osmotic system is activated by opening the first valve, fluid is drawn in through the sucker and expelled through the second burst valve. Fluid continues to flow until all the salt contained in the sucker is dissolved or until tissue is drawn into the sucker. As liminal fluid is drawn through the osmotic pump system, solutes build up between the tissue and the first valve, reducing osmotic pressure. In some embodiments, the solute buildup stalls the pump before the tissue contacts the valve, preventing tissue damage. In some embodiments, a burst valve is used on the far side of the osmotically-driven sucker rather than a one-way valve, such that luminal fluid eventually clears the saline chamber and the osmotic flow reverses, actively pushing the subject's tissue out of the sucker. In some embodiments, the ingestible device may be anchored to the interior surface of tissues forming the GI tract of a subject. In one embodiment, the ingestible device comprises a connector for anchoring the device to the interior surface of the GI tract. The connector may be operable to ingestible device to the interior surface of the GI tract using an adhesive, negative pressure and/or fastener.
In some embodiments a device comprises a tract stimulator and/or monitor IMD comprising a housing enclosing electrical stimulation and/or monitoring circuitry and a power source and an elongated flexible member extending from the housing to an active fixation mechanism adapted to be fixed into the GI tract wall is disclosed. After fixation is effected, the elongated flexible member bends into a preformed shape that presses the housing against the mucosa so that forces that would tend to dislodge the fixation mechanism are minimized. The IMD is fitted into an esophageal catheter lumen with the fixation mechanism aimed toward the catheter distal end opening whereby the bend in the flexible member is straightened. The catheter body is inserted through the esophagus into the GI tract cavity to direct the catheter distal end to the site of implantation and fix the fixation mechanism to the GI tract wall. The IMD is ejected from the lumen, and the flexible member assumes its bent configuration and lodges the hermetically sealed housing against the mucosa. A first stimulation/sense electrode is preferably an exposed conductive portion of the housing that is aligned with the bend of the flexible member so that it is pressed against the mucosa. A second stimulation/sense electrode is located at the fixation site.
In some embodiments a device includes a fixation mechanism to anchor the device to tissue within a body lumen, and a mechanism to permit selective de-anchoring of the device from the tissue anchoring site without the need for endoscopic or surgical intervention. An electromagnetic device may be provided to mechanically actuate the de-anchoring mechanism. Alternatively, a fuse link may be electrically blown to de-anchor the device. As a further alternative, a rapidly degradable bonding agent may be exposed to a degradation agent to de-anchor the device from a bonding surface within the body lumen.
In some embodiments a device is as disclosed in patent publication WO2015112575A1, incorporated by reference herein in its entirety.

In some embodiments, the ingestible device contains an electric energy emitting means, a radio signal transmitting means, a medicament storage means and a remote actuatable medicament releasing means. The capsule signals a remote receiver as it progresses through the alimentary tract in a previously mapped route and upon reaching a specified site is remotely triggered to release a dosage of medicament. Accordingly, in some embodiments, releasing the IL-12/IL-23 inhibitor is triggered by a remote electromagnetic signal.
In some embodiments, the ingestible device includes a housing introducible into a body cavity and of a material insoluble in the body cavity fluids, but formed with an opening covered by a material which is soluble in body cavity fluids. A diaphragm divides the interior of the housing into a medication chamber including the opening, and a control chamber. An electrolytic cell in the control chamber generates a gas when electrical current is passed therethrough to deliver medication from the medication chamber through the opening into the body cavity at a rate controlled by the electrical current. Accordingly, in some embodiments, releasing the IL-12/IL-23 inhibitor is triggered by generation in the composition of a gas in an amount sufficient to expel the IL-12/IL-23 inhibitor.
In some embodiments, the ingestible device includes an oral drug delivery device having a housing with walls of water permeable material and having at least two chambers separated by a displaceable membrane.

In some embodiments, the disclosure, provides a method of measuring the presence, absence or amount of one or more analytes from one or more samples in the gastrointestinal tract. In some embodiments the one or more analytes are measured multiple times, for example, at different time points or at different locations. In one embodiment, a single device measures one or more analytes or more time points or locations; thereby creating a “molecular map” of a physiological region. Measurements can be taken at any location in the gastrointestinal tract. For example, in one aspect, analytes from samples from one or more of the duodenum, jejunum, ileum, ascending colon, transverse colon or descending colon can be measured to create a molecular map of the small and large intestine. In one aspect, the sample is from the duodenum. In one aspect, In one aspect, the sample is from the jejunum. In one aspect, the sample is from the ileum.

Dicarboxylic acids, having between about 6 and about 14 carbon atoms in their carbon atom skeleton are particularly useful in the treatment of disorders of the skin and mucosal membranes that involve microbial. Suitable dicarboxylic acid moieties include, but are not limited to, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, 1,11-undecanedioic acid, 1,12-dodecanedioic acid, 1,13-tridecanedioic acid and 1,14-tetradecanedioic acid. Thus, in one or more embodiments of the present disclosure, dicarboxylic acids, having between about 6 and about 14 carbon atoms in their carbon atom skeleton, as well as their salts and derivatives (e.g., esters, amides, mercapto-derivatives, anhydrides), are useful immunomodulators in the treatment of disorders of the skin and mucosal membranes that involve inflammation. Azelaic acid and its salts and derivatives are preferred. It has antibacterial effects on both aerobic and anaerobic organisms, particularly Propionibacterium acnes and Staphylococcus epidermidis, normalizes keratinization, and has a cytotoxic effect on malignant or hyperactive melanocytes. In a preferred embodiment, the dicarboxylic acid is azelaic acid in a concentration greater than 10%. Preferably, the concentration of azelaic acid is between about 10% and about 25%. In such concentrates, azelaic acid is suitable for the treatment of a variety of skin disorders, such as acne, rosacea and hyperpigmentation.
In some embodiments, the antibiotic agent is an antibiotic metal. A number of metals ions have been shown to possess antibiotic activity, including silver, copper, zinc, mercury, tin, lead, bismutin, cadmium, chromium and ions thereof. It has been theorized that these antibiotic metal ions exert their effects by disrupting respiration and electron transport systems upon absorption into bacterial or fungal cells. Anti-microbial metal ions of silver, copper, zinc, and gold, in particular, are considered safe for in vivo use. Anti-microbial silver and silver ions are particularly useful due to the fact that they are not substantially absorbed into the body. Thus, in one or more embodiment, the antibiotic metal consists of an elemental metal, selected from the group consisting of silver, copper, zinc, mercury, tin, lead, bismutin, cadmium, chromium and gold, which is suspended in the composition as particles, microparticles, nanoparticles or colloidal particles. The antibiotic metal can further be intercalated in a chelating substrate.
In further embodiments, the antibiotic metal is ionic. The ionic antibiotic metal can be presented as an inorganic or organic salt (coupled with a counterion), an organometallic complex or an intercalate. Non-binding examples of counter inorganic and organic ions are sulfadiazine, acetate, benzoate, carbonate, iodate, iodide, lactate, laurate, nitrate, oxide, and palmitate, a negatively charged protein. In preferred embodiments, the antibiotic metal salt is a silver salt, such as silver acetate, silver benzoate, silver carbonate, silver iodate, silver iodide, silver lactate, silver laurate, silver nitrate, silver oxide, silver palmitate, silver protein, and silver sulfadiazine.
In one or more embodiments, the antibiotic metal or metal ion is embedded into a substrate, such as a polymer, or a mineral (such as zeolite, clay and silica).
In one or more embodiments, the antibiotic agent includes strong oxidants and free radical liberating compounds, such as oxygen, hydrogen peroxide, benzoyl peroxide, elemental halogen species, as well as oxygenated halogen species, bleaching agents (e.g., sodium, calcium or magnesium hypochloride and the like), perchlorite species, iodine, iodate, and benzoyl peroxide. Organic oxidizing agents, such as quinones, are also included. Such agents possess a potent broad-spectrum activity.
In one or more embodiments, the antibiotic agent is a cationic antimicrobial agent. The outermost surface of bacterial cells universally carries a net negative charge, making them sensitive to cationic substances. Examples of cationic antibiotic agents include: quaternary ammonium compounds (QAC's)—QAC's are surfactants, generally containing one quaternary nitrogen associated with at least one major hydrophobic moiety; alkyltrimethyl ammonium bromides are mixtures of where the alkyl group is between 8 and 18 carbons long, such as cetrimide (tetradecyltrimethylammonium bromide); benzalkonium chloride, which is a mixture of n-alkyldimethylbenzyl ammonium chloride where the alkyl groups (the hydrophobic moiety) can be of variable length; dialkylmethyl ammonium halides; dialkylbenzyl ammonium halides; and QAC dimmers, which bear bi-polar positive charges in conjunction with interstitial hydrophobic regions.
In one or more embodiments, the cationic antimicrobial agent is a polymer. Cationic antimicrobial polymers include, for example, guanide polymers, biguanide polymers, or polymers having side chains containing biguanide moieties or other cationic functional groups, such as benzalkonium groups or quarternium groups (e.g., quaternary amine groups). It is understood that the term “polymer” as used herein includes any organic material including three or more repeating units, and includes oligomers, polymers, copolymers, block copolymers, terpolymers, etc. The polymer backbone may be, for example a polyethylene, polypropylene or polysilane polymer.
In one or more embodiments, the cationic antimicrobial polymer is a polymeric biguanide compound. When applied to a substrate, such a polymer is known to form a barrier film that can engage and disrupt a microorganism. An exemplary polymeric biguanide compound is polyhexamethylene biguanide (PHMB) salts. Other exemplary biguanide polymers include, but are not limited to poly(hexamethylenebiguanide), poly(hexamethylenebiguanide) hydrochloride, poly(hexamethylenebiguanide) gluconate, poly(hexamethylenebiguanide) stearate, or a derivative thereof. In one or more embodiments, the antimicrobial material is substantially water-insoluble.
In some embodiments, the antibiotic agent is selected from the group of biguanides, triguanides, bisbiguanides and analogs thereof.
Guanides, biguanides, biguanidines and triguanides are unsaturated nitrogen containing molecules that readily obtain one or more positive charges, which make them effective antimicrobial agents. The basic structures a guanide, a biguanide, a biguanidine and a triguanide are provided below.
In some embodiments, the guanide, biguanide, biguanidine or triguanide, provide bi-polar configurations of cationic and hydrophobic domains within a single molecule.
Examples of guanides, biguanides, biguanidines and triguanides that are currently been used as antibacterial agents include chlorhexidine and chlorohexidine salts, analogs and derivatives, such as chlorhexidine acetate, chlorhexidine gluconate and chlorhexidine hydrochloride, picloxydine, alexidine and polihexanide. Other examples of guanides, biguanides, biguanidines and triguanides that can conceivably be used according to the present disclosure are chlorproguanil hydrochloride, proguanil hydrochloride (currently used as antimalarial agents), mefformin hydrochloride, phenformin and buformin hydrochloride (currently used as antidiabetic agents).

A “photosensitizer” as used herein refers to a sensitizer for generation of singlet oxygen usually by excitation with light. Exemplary photosensitizers suitable for use include those described in U.S. Pat. Nos. 6,251,581, 5,516,636, 8,907,081, 6,545,012, 6,331,530, 8,247,180, 5,763,602, 5,705,622, 5,516,636, 7,217,531, and U.S. Patent Publication No. 2007/0059316, all of which are herein expressly incorporated by reference in their entireties. The photosensitizer can be photoactivatable (e.g., dyes and aromatic compounds) or chemiactivated (e.g., enzymes and metal salts). When excited by light the photosensitizer is usually a compound comprised of covalently bonded atoms, usually with multiple conjugated double or triple bonds. The compound should absorb light in the wavelength range of 200-1100 nm, usually 300-1000 nm, e.g., 450-950 nm, with an extinction coefficient at its absorbance maximum greater than 500 M−lcm−1, e.g., at least 5000 M−lcm−1, or at least 50,000 M−lcm−1 at the excitation wavelength. The lifetime of an excited state produced following absorption of light in the absence of oxygen will usually be at least 100 nsec, e.g., at least 1 μsec. In general, the lifetime must be sufficiently long to permit energy transfer to oxygen, which will normally be present at concentrations in the range of 10−5 to 1031 M depending on the medium. The sensitizer excited state will usually have a different spin quantum number (s) than its ground state and will usually be a triplet (s=1) when, as is usually the case, the ground state is a singlet (s=0). In some embodiments, the sensitizer will have a high intersystem crossing yield. That is, photoexcitation of a sensitizer will produce the long lived state (usually triplet) with an efficiency of at least 10%, at least 40%, e.g., greater than 80%. The photosensitizer will usually be at most weakly fluorescent under the assay conditions (quantum yield usually less than 0.5, or less than 0.1).
Photosensitizers that are to be excited by light will be relatively photostable and will not react efficiently with singlet oxygen. Several structural features are present in most useful sensitizers. Most sensitizers have at least one and frequently three or more conjugated double or triple bonds held in a rigid, frequently aromatic structure. They will frequently contain at least one group that accelerates intersystem crossing such as a carbonyl or imine group or a heavy atom selected from rows 3-6 of the periodic table, especially iodine or bromine, or they may have extended aromatic structures. Typical sensitizers include acetone, benzophenone, 9-thioxanthone, eosin, 9,10-dibromoanthracene, methylene blue, metallo-porphyrins, such as hematoporphyrin, phthalocyanines, chlorophylls, rose bengal, buckminsterfullerene, etc., and derivatives of these compounds having substituents of 1 to 50 atoms for rendering such compounds more lipophilic or more hydrophilic and/or as attaching groups for attachment. Examples of other photosensitizers that may be utilized are those that have the above properties and are enumerated in N. J. Turro, “Molecular Photochemistry,” page 132, W. A. Benjamin Inc., N.Y. 1965.
In some embodiments, the photosensitizers are relatively non-polar to assure dissolution into a lipophilic member when the photosensitizer is incorporated in an oil droplet, liposome, latex particle, etc.
In some embodiments, the photosensitizers suitable for use herein include other substances and compositions that can produce singlet oxygen with or without activation by an external light source. Thus, for example, molybdate (MoO4−) salts and chloroperoxidase and myeloperoxidase plus bromide or chloride ion (Kanofsky, J. Biol. Chem. (1983) 259 5596) have been shown to catalyze the conversion of hydrogen peroxide to singlet oxygen and water. Either of these compositions can, for example, be included in particles and used in the assay method wherein hydrogen peroxide is included as an ancillary reagent, chloroperoxidase is bound to a surface and molybdate is incorporated in the aqueous phase of a liposome. Also included within the scope of the disclosure as photosensitizers are compounds that are not true sensitizers but which on excitation by heat, light, or chemical activation will release a molecule of singlet oxygen. The best known members of this class of compounds includes the endoperoxides such as 1,4-biscarboxyethyl-1,4-naphthalene endoperoxide, 9,10-diphenylanthracene-9, 10-endoperoxide and 5,6,11,12-tetraphenylnaphthalene 5,12-endoperoxide. Heating or direct absorption of light by these compounds releases singlet oxygen.
A “chemiluminescent compound” as used herein refers to a substance that undergoes a chemical reaction with singlet oxygen to form a metastable intermediate that can decompose with the simultaneous or subsequent emission of light within the wavelength range of 250 to 1200 nm. Exemplary chemiluminescent compounds suitable for use include those described in U.S. Pat. Nos. 6,251,581 and 7,709,273, and Patent Cooperation Treaty (PCT) International Application Publication No. WO1999/042838. Exemplary chemiluminescent compounds includes the following:
All of the above mentioned applications are hereby expressly incorporated by reference herein in their entireties. Emission will usually occur without the presence of an energy acceptor or catalyst to cause decomposition and light emission. In some embodiments, the intermediate decomposes spontaneously without heating or addition of ancillary reagents following its formation. However, addition of a reagent after formation of the intermediate or the use of elevated temperature to accelerate decomposition will be required for some chemiluminescent compounds. The chemiluminescent compounds are usually electron rich compounds that react with singlet oxygen, frequently with formation of dioxetanes or dioxetanones. Exemplary of such compounds are enol ethers, enamines, 9-alkylidenexanthans, 9-alkylidene-N-alkylacridans, aryl vinyl ethers, dioxenes, arylimidazoles and lucigenin. Other chemiluminescent compounds give intermediates upon reaction with singlet oxygen, which subsequently react with another reagent with light emission. Exemplary compounds are hydrazides such as luminol and oxalate esters.
The chemiluminescent compounds of interest will generally emit at wavelengths above 300 nanometers and usually above 400 nm. Compounds that alone or together with a fluorescent molecule emit light at wavelengths beyond the region where serum components absorb light will be of particular use. The fluorescence of serum drops off rapidly above 500 nm and becomes relatively unimportant above 550 nm. Therefore, when the analyte is in serum, chemiluminescent compounds that emit light above 550 nm, e.g., above 600 nm may be suitable for use. In order to avoid autosensitization of the chemiluminescent compound, in some embodiments, the chemiluminescent compounds do not absorb light used to excite the photosensitizer. In some embodiments, the sensitizer is excited with light wavelengths longer than 500 nm, it will therefore be desirable that light absorption by the chemiluminescent compound be very low above 500 nm.
Where long wave length emission from the chemiluminescent compound is desired, a long wavelength emitter such as a pyrene, bound to the chemiluminescent compound can be used. Alternatively, a fluorescent molecule can be included in the medium containing the chemiluminescent compound. In some embodiments, fluorescent molecules will be excited by the activated chemiluminescent compound and emit at a wavelength longer than the emission wavelength of the chemiluminescent compound, usually greater than 550 nm. It is usually also desirable that the fluorescent molecules do not absorb at the wavelengths of light used to activate the photosensitizer. Examples of useful dyes include rhodamine, ethidium, dansyl, Eu(fod)3, Eu(TTA)3, Ru(bpy)3++ (wherein bpy=2,2′-dipyridyl), etc. In general these dyes act as acceptors in energy transfer processes and in some embodiments, have high fluorescent quantum yields and do not react rapidly with singlet oxygen. They can be incorporated into particles simultaneously with the incorporation of the chemiluminescent compound into the particles.
In some embodiments, the disclosure provides diffractive optics detection technology that can be used with, for example, ingestible device technology. In certain embodiments, an ingestible device includes the diffractive optics technology (e.g., diffractive optics detection system). In certain embodiments, the disclosure provides diffractive optics technology (e.g., diffractive optics detection systems) that are used outside the body of subject. As an example, an ingestible device can be used to obtain one more samples in the body (e.g., in the gastrointestinal tract) of a subject, and the diffractive optics technology can be used to analyze the sample(s). Such analysis can be performed in vivo (e.g., when the ingestible device contains the diffractive optics).
Diffraction is a phenomenon that occurs due to the wave nature of light. When light hits an edge or passes through a small aperture, it is scattered in different directions. But light waves can interfere to add (constructively) and subtract (destructively) from each other, so that if light hits a non-random pattern of obstacles, the subsequent constructive and destructive interference will result in a clear and distinct diffraction pattern. A specific example is that of a diffraction grating, which is of uniformly spaced lines, typically prepared by ruling straight, parallel grooves on a surface. Light incident on such a surface produces a pattern of evenly spaced spots of high light intensity. This is called Bragg scattering, and the distance between spots (or ‘Bragg scattering peaks’) is a unique function of the diffraction pattern and the wavelength of the light source. Diffraction gratings, like focusing optics, can be operated in both transmission and reflection modes.
In general, the light used in the diffractive optics can be of any appropriate wavelength. Exemplary wavelengths include visible light, infrared red (IR) and ultraviolet (UV). Optionally, the light can be monochromatic or polychromatic. The light can be coherent or incoherent. The light can be collimated or non-collimated. In some embodiments, the light is coherent and collimated. Generally, any appropriate light source may be used, such as, for example, a laser (e.g., a laser diode) or a light emitting diode. In some embodiments, the light source is a laser diode operating at 670 nm wavelength, e.g., at 3 mWatts power. Optionally, an operating wavelength of a laser diode can be 780 nm, e.g., when larger grating periods are used. In certain embodiments, the light source is a laser, such as, for example, a He—Ne laser, a Nd:YVO4 laser, or an argon-ion laser. In some embodiments, the light source is a low power, continuous waver laser.
The diffracted light can be detected using any appropriate light detector(s). Examples of light detectors include photodetectors, such as, for example, position sensitive photodiodes, photomultiplier tubes (PMTs), photodiodes (PDs), avalanche photodiodes (APDs), charged-coupled device (CCD) arrays, and CMOS detectors. In some embodiments, the diffracted light is detected via one or more individual photodiodes.
In general, the diffraction grating is made of a material that is transparent in the wavelength of the radiation used to illuminate the sensor. Any appropriate material may be used for the diffraction grating substrate, such as glass or a polymer. Exemplary polymers include polystyrene polymers (PSEs), cyclo-olefin polymers (COPs), polycarbonate polymers, polymethyl methacrylates, and methyl methacrylate styrene copolymers. Exemplary COPs include Zeonex (e.g., Zeonex E48R, Zeonex F52R).
The light may be incident on the diffraction grating any appropriate angle. In some embodiments, the light is incident on the diffraction grating with an angle of incidence of from 30° to 80° (e.g., from 40° to 80°, from 50° to 70°, from 55° to 65°,60°). Optionally, the system is configured so that that diffractive grating and light source can move relative to each other
In general, the light detector can be positioned with respect to the diffractive grating so that the diffraction grating can be illuminated at a desired angle of incidence and/or so that diffracted light can be detected at a desired angle and/or so that diffracted light of a desired order can be detected.
The period P of the diffraction grating can be selected as desired. In some embodiments, the period P is from 0.5 microns to 50 microns (e.g., from one micron to 15 microns, from one micron to five microns). In some embodiments, the grating is a repeating patter of 1.5 micron and 4.5 micron lines with a period of 15 microns.
The height h of the diffraction grating can be selected as desired. In certain embodiments, the height h is from one nanometer to about 1000 nanometers (e.g., from about five nanometers to about 250 nanometers, from five nanometers to 100 nanometers).
In general, the diffractive optics can be prepared using any appropriate method, such as, for example, surface ablation, photolithograph (e.g., UV photolithography), laser etching, electron beam etching, nano-imprint molding, or microcontact printing.
Optionally, the diffractive optics system can include one or more additional optical elements, such as, for example, one or more mirrors, filters and/or lenses. Such optical elements can, for example, be arranged between the light source and the diffractive grating and/or between the diffractive grating and the detector.
In some of the embodiments of the devices described herein, a primary binding partner specifically binds to a secondary binding partner through non-covalent interactions (e.g., electrostatic, van der Waals, hydrophobic effect). In some embodiments, a primary binding partner specifically binds to a secondary binding partner via a covalent bond (e.g., a polar covalent bond or a non-polar covalent bond). In some embodiments of any of the devices described herein, the primary and the secondary binding partner can be interchanged. For example, the primary binding partner can be biotin, or a derivative thereof, and the secondary binding partner is avidin, or a derivative thereof. In other examples, the primary binding partner can be avidin, or a derivative thereof, and the secondary binding partner is biotin.
In some embodiments, the binding of the primary and the secondary binding partner is essentially irreversible. In some embodiments, the binding of the primary and the secondary binding partner is reversible. In some embodiments, the primary binding partner is CaptAvidin™ biotin-binding protein and the secondary binding partner is biotin, or vice versa. In some embodiments, the primary binding partner is DSB-X™ biotin and the secondary binding partner is avidin, or vice versa. In some embodiments, the primary binding partner is desthiobiotin and the secondary binding partner is avidin, or vice versa (Hirsch et al., Anal Biochem. 308(2):343-357, 2002). In some embodiments, the primary binding partner is glutathione (GSH) or a derivative thereof, and the secondary binding partner is glutathione-S-transferase (GST).
In some embodiments, the primary binding partner can bind to a target analyte that is a nucleic acid (e.g., a DNA molecule, a RNA molecule). In some embodiments, the primary binding partner comprises a portion of a nucleic acid that is complementary to the nucleic acid sequence of the target analyte.
In some embodiments of any of the devices described herein, the device can include a label that binds to the target analyte and does not prevent binding of the target analyte to the primary binding partner. In some embodiments, the label can amplify the diffraction signal of the target analyte.
In some embodiments, the label is from about 1 nm to 200 nm (e.g., about 50 nm to about 200 nm).
In some embodiments, the label (e.g., any of the labels described herein) includes one or more antibodies (e.g., any of the antibodies and/or antibody fragments described herein).
In some embodiments, the label is a nanoparticle (e.g., a gold nanoparticle) that includes the primary binding partner that has a nucleic acid sequence that is complementary to the target analyte, and is covalently linked to the nanoparticle.
One or more additional steps can be performed in any of the methods described herein. In some embodiments, the one or more additional steps are performed: prior to the binding of the primary binding partner to the secondary binding partner, after the binding of the primary binding partner to the secondary binding partner, prior to the binding of the primary binding partner to the target analyte, or after the binding of the primary binding partner to the target analyte.
In some embodiments of any of the methods described herein, the determining step (during which the primary binding partner binds to the target analyte is detected) can occur in at least 15 seconds. In some embodiments, the binding of the primary binding partner to the target analyte can occur during a period of time of, for example, five at least seconds.
In some embodiments, the one or more additional steps can include: a blocking of the sensors step, at least one wash step, a capturing step, and/or a filtering step. In some embodiments, the blocking step can include blocking a sensor within the ingestible device with a solution comprising at least 1% bovine serum albumin (BSA) in a buffered solution (e.g., phosphate buffered saline (PBS), Tris buffered saline (TBS)). In some embodiments, the at least one wash step can include washing with a buffered solution (e.g., phosphate buffered saline (PBS), Tris buffered saline (TBS)). In general, blocking is performed during capsule manufacture, rather than in vivo.
In some embodiments, the capturing step includes enriching the target analyte. In some embodiments, the capturing step includes physically separating the target analyte from the remaining sample using a filter, a pore, or a magnetic bead. In some embodiments, the target analyte is captured by size exclusion.
In some embodiments, the disclosure provides methods of obtaining, culturing, and/or detecting target cells and/or target analytes in vivo within the gastrointestinal (GI) tract or reproductive tract of a subject. Associated devices are also disclosed. The methods and devices described provide a number of advantages for obtaining and/or analyzing fluid samples from a subject. In some embodiments, diluting the fluid sample increases the dynamic range of analyte detection and/or reduces background signals or interference within the sample. For example, interference may be caused by the presence of non-target analytes or non-specific binding of a dye or label within the sample. In some embodiments, culturing the sample increases the concentration of target cells and/or target analytes produced by the target cells thereby facilitating their detection and/or characterization.
In certain embodiments, the methods and devices a described herein may be used to obtain information regarding bacteria populations in the GI tract of a subject. This has a number of advantages and is less invasive than surgical procedures such as intubation or endoscopy to obtain fluid samples from the GI tract. The use of an ingestible device as described herein also allows for fluid samples to be obtained and data to be generated on bacterial populations from specific regions of the GI tract.
In some embodiments, the methods and devices described herein may be used to generate data such as by analyzing the fluid sample, dilutions thereof or cultured samples for one or more target cells and/or target analytes. The data may include, but is not limited to, the types of bacteria present in the fluid sample or the concentration of bacteria in specific regions of the GI tract. Such data may be used to determine whether a subject has an infection, such as Small Intestinal Bacterial Overgrowth (SIBO), or to characterize bacterial populations within the GI tract for diagnostic or other purposes. Thus, in some embodiments, analytes disclosed herein are indicative of disorders of the gastrointestinal tract associated with anomalous bacterial populations.
For example, in one aspect, the data may include, but is not limited to, the concentration of bacteria in a specific region of the GI tract that is one or more of the duodenum, jejunum, ileum, ascending colon, transverse colon or descending colon. In one aspect, the specific region of the GI tract is the duodenum. In one aspect, the specific region of the GI tract is the jejunum. In one aspect, the specific region of the GI tract is the ileum. In one aspect, the specific region of the GI tract is the ascending colon. In one aspect, the specific region of the GI tract is the transverse colon. In one aspect, the specific region of the GI tract is the descending colon. In a related embodiment, the data may be generated every one or more days to monitor disease flare-ups, or response to the therapeutic agents disclosed herein.
Data may be generated after the device has exited the subject, or the data may be generated in vivo and stored on the device and recovered ex vivo. Alternatively, the data can be transmitted wirelessly from the device while the device is passing through the GI tract of the subject or in place within the reproductive tract of the subject.

In some embodiments, the dilution chambers define a fluid volume ranging from about 10 μL to about 1 mL. The dilution chambers may define a fluid volume less than or equal to about 500 μL less than or equal to about 250 μL, less than or equal to about 100 μL, or less than or equal to about 50 μL. In certain embodiments, the dilution chambers define a fluid volume of greater than or equal to about 10 μL, greater than or equal to about 20 μL, greater than or equal to about 30 μL, or greater than or equal to about 50 μL. In some embodiments, the dilution chambers define a fluid volume between about 10 μL and 500 μL, between about 20 μL and 250 μL, between about 30 μL and 100 μL or about 50 μL.
In some embodiments, dilution fluid in the device is combined with all or part of the fluid sample, or dilution thereof, to produce one or more dilutions. In certain embodiments, the dilution fluid is sterile media suitable for culturing one or more target cells within the dilution chambers.
In certain embodiments, the one or more dilution chambers may be filled with the dilution fluid prior to a patient ingesting the ingestible device. In some embodiments, the dilution fluid may be added into the one or more dilution chambers in vivo from a reservoir of the ingestible device. Sampling and dilution of the GI fluid sample may take place in vivo. For example, an actuator of the ingestible device may pump the dilution fluid from the reservoir into a dilution chamber when it is determined that the ingestible device is located at a predetermined location within the GI tract. In some embodiments, the dilution chambers each contain a volume of sterile media suitable for culturing a fluid sample from the GI tract or reproductive tract. In certain embodiments, the dilution chambers are at least 95%, at least 97%, at least 98%, or at least 99% full of sterile media. In some embodiments, the dilution chambers each contain oxygen to facilitate aerobic bacteria growth. In certain embodiments, a non-dilution chamber comprises oxygen and is added to one or more of the dilution chambers to facilitate aerobic bacteria growth.
In some embodiments, the culturing may take place in vivo immediately after the GI fluid sample has been diluted. Or alternatively, the culturing may take place ex vivo, e.g., when the ingestible device has been evacuated and recovered such that the dilution chamber containing the diluted GI fluid sample may be extracted and the culturing may be performed in a laboratory. The recovery of the ingestible device may be performed in a similar manner as embodiments described in U.S. Provisional Application No. 62/434,188, filed on Dec. 14, 2016, which is herein expressly incorporated by reference in its entirety.
As used herein “culturing” refers to maintaining target cells in an environment that allows a population of one or more target cells to increase in number through cell division. For example, in some embodiments, “culturing” may include combining the cells with media in an dilution chamber at a temperature that permits cell growth, optionally a temperature found in vivo within the GI tract or reproductive tract of a subject. In certain embodiments, the cells are cultured at a temperature between about 35° C. and 42° C.
As used herein “dilution fluid” refers to a fluid within the device for diluting a fluid sample from the GI tract or reproductive tract. In some embodiments, the dilution fluid is an aqueous solution. In certain embodiments, the dilution fluid comprises one or more agents that promote or inhibit the growth of an organism, such as a fungus or bacteria. In some embodiments, the dilution fluid comprises one or more agents that facilitate the detection of a target analyte, such as dyes or binding agents for target analytes.
In some embodiments, the dilution fluid is a sterile media. As used herein, “sterile media” refers to media that does not contain any viable bacteria or other cells that would grow and increase in number through cell division. Media may be rendered sterile by various techniques known in the art such as, but not limited to, autoclaving and/or preparing the media using aseptic techniques. In certain embodiments, the media is a liquid media. Examples of media suitable for culturing bacteria include nutrient broth, Lysogeny Broth (LB) (also known as Luria Broth), Wilkins chalgren, and Tryptic Soy Broth (TSB), Other growth or culture media known in the art may also be used in the methods and devices described herein. In some embodiments, the media has a carbon source, such as glucose or glycerol, a nitrogen source such as ammonium salts or nitrates or amino acids, as well as salts and/or trace elements and vitamins required for microbial growth. In certain embodiments, the media is suitable for maintaining eukaryotic cells. In some embodiments, the media comprises one or more agents that promote or inhibit the growth of bacteria, optionally agents that promote or inhibit the growth of specific types of bacteria.
In certain embodiments, the media is a selective media. As used herein, “selective media” refers to a media that allows certain types of target cells to grow and inhibits the growth of other organisms. Accordingly, the growth of cells in a selective media indicates the presence of certain types of cells within the cultured sample. For example, in some embodiments, the media is selective for gram-positive or gram-negative bacteria. In certain embodiments, the media contains crystal violet and bile salts (such as found in MacConkey agar) that inhibit the growth of gram-positive organisms and allows for the selection and isolation of gram-negative bacteria. In some embodiments, the media contains a high concentration of salt (NaCl) (such as found in Mannitol salt agar) and is selective for Gram-positive bacteria. In some embodiments, the media selectively kills eukaryotic cells or only grows prokaryotic cells, for example, using a media comprising Triton™ X-100. In certain embodiments, the media selectively kills prokaryotic cells (or alternatively only grows eukaryotic cells), for example, using a media that comprises antibiotics.
In some embodiments, the media is an indicator media. As used herein, “indicator media” refers to a media that contains specific nutrients or indicators (such as, but not limited to neutral red, phenol red, eosin y, or methylene blue) that produce a detectable signal when a certain type of cells are cultured in the indicator media.
In some embodiments, the disclosure provides a composition comprising a dye and optionally a reagent for selective lysis of eukaryotic cells. In certain embodiments, the composition comprises both a dye and a reagent for selective lysis of eukaryotic cells. In some embodiments, the composition further comprises one or more reagents independently selected from the group consisting of: a second reagent for selective lysis of eukaryotic cells (e.g., Triton X-100), an electrolyte (e.g., MgCl2), an anti-fungi reagent (e.g., amphotericin-B), and an antibiotic. In some embodiments, the composition comprises water and is in the form of an aqueous solution. In some embodiments, the composition is a solid or semi-solid. In some embodiments, the compositions described here are suitable for use in a kit or device for detecting or quantifying viable bacterial cells in a sample. In some embodiments, such a device is an ingestible device for detecting or quantifying viable bacterial cells in vivo (e.g., in the GI tract). In some embodiments, viable bacterial cells in a sample are detected or quantified in the presence of one or more antibiotics to determine antibiotic resistance of the bacteria in the sample. In some embodiments, anomalous bacterial populations in a sample may be detected or quantified, for example through the use of one a composition comprising a dye as disclosed herein, to determine whether a subject has an infection, such as Small Intestinal Bacterial Overgrowth (SIBO), or to characterize bacterial populations within the GI tract for diagnostic or other purposes.
In some embodiments, a method comprises: (a) contacting the sample with a composition as described herein; and (b) measuring total fluorescence or rate of change of fluorescence as a function of time of said sample, thereby detecting viable bacterial cells in said sample. In some embodiments, a control as described herein may be employed in the method. In some embodiments, the total fluorescence or the rate of change of fluorescence as a function of time of the sample is measured over multiple time points for an extended period of time in step (b), thereby detecting viable bacterial cells in said sample. In some embodiments, the method further comprises correlating the total fluorescence or the rate of change of fluorescence as a function of time determined in step (b) to the number of viable bacterial cells in the sample. In some embodiments, the rate of change of fluorescence as a function of time of the sample measured over multiple time points is determined and compared to the rate of change of fluorescence as a function of time of a control measured over the same time points to determine the number of viable bacterial cells in the sample. In some embodiments, the method does not require ex vivo plating or culturing. In some embodiments, the method does not require aspiration. In some embodiments, the method is performed in vivo (e.g., in an ingestible device in vivo). In some embodiments, the method comprises communicating the results of the onboard assay(s) to an ex vivo receiver.
In certain embodiments, a kit comprises a composition as described herein and instructions, e.g., for detecting or quantifying viable bacterial cells in a sample. In some embodiments, a device comprises a composition as described herein, e.g., for detecting or quantifying viable bacterial cells in a sample. The detection of live cells, as opposed to the detection of bacterial components (such as endotoxins) which can be present in the sample environment and lead to conflicting results, is the gold standard of viable plate counting and represents one of the advantages of the compositions and methods described herein.
The systems employ methods, compositions and detection systems found to accurately and reliably correlate fluorescence to total bacteria count (TBC) in an autonomous, ingestible device, or other similarly-sized device.

In some embodiments, the dye suitable for use herein is a dye that is capable of being internalized by a viable cell, binding to or reacting with a target component of the viable cell, and having fluorescence properties that are measurably altered when the dye is bound to or reacted with the target component of the viable cell. In some embodiments, the dye herein is actively internalized by penetrating viable cells through a process other than passible diffusion across cell membranes. Such internalization includes, but is not limited to, internalization through cell receptors on cell surfaces or through channels in cell membranes. In some embodiments, the target component of a viable cell to which the dye is bound to or reacted with is selected from the group consisting of: nucleic acids, actin, tubulin, enzymes, nucleotide-binding proteins, ion-transport proteins, mitochondria, cytoplasmic components, and membrane components. In some embodiments, the dye suitable for use herein is a fluorogenic dye that is capable of being internalized and metabolized by a viable cell, and wherein said dye fluoresces when metabolized by the viable cell. In some embodiments, the dye is a chemiluminescent dye that is capable of being internalized and metabolized by a viable cell, and wherein said dye becomes chemiluminescent when metabolized by the viable cell.
In some embodiments, the composition comprises a dye that fluoresces when bond to nucleic acids. Examples of such dyes include, but are not limited to, acridine orange (U.S. Pat. No. 4,190,328); calcein-AM (U.S. Pat. No. 5,314,805); DAPI; Hoechst 33342; Hoechst 33258; PicoGreen™; SYTO® 16; SYBR® Green I; Texas Red®; Redmond Red™; Bodipy® Dyes; Oregon Green™; ethidium bromide; and propidium iodide.

Examples of such dyes include, but are not limited to, (CBZ-Ala-Ala-Ala-Ala)2-R110 elastase 2; (CBZ-Ala-Ala-Asp)2-R110 granzyme B; and 7-amino-4-methylcoumarin, N-CBZ-L-aspartyl-L-glutamyl-L-valyl-L-aspartic acid amide.
In some embodiments, the composition comprises a dye selected from the group consisting of resazurin, FDA, Calcein AM, and SYTO® 9. In some embodiments, the dye is FDA or SYTO® 9.
SYTO® 9, when used alone, labels the nucleic acid of bacteria cells. The excitation/emission wavelengths for SYTO® 9 is 480/500 nm, with the background remaining non-fluorescent. See, e.g., J. Appl. Bacteriol. 72, 410 (1992); Lett. Appl. Microbiol. 13, 58 (1991); Curr. Microbiol. 4, 321 (1980); J. Microbiol. Methods 13, 87 (1991); and Microbiol. Rev. 51, 365 (1987); and J. Med. Microbiol. 39, 147 (1993).
FDA is a non-polar, non-fluorescent compound that can cross the membranes of mammalian and bacterial cells. The acetyl esterases (present only within viable cells) hydrolyze the FDA into the fluorescent compound fluorescein. Fluorescein is a fluorescent polar compound that is retained within these cells. Living cells can be visualized in a photospectrometer when assayed with an excitation wavelength of 494 nm and an emission wavelength of 518 nm. See, e.g., Brunius, G. (1980), “Technical aspects of the use of 3′,6′-diacetyl fluorescein for vital fluorescent staining of bacteria,” Current Microbiol. 4:321-323; Jones, K. H. and Senft, J. A. (1985), “An improved method to determine cell viability by simultaneous staining with fluorescein diacetate-propidium iodide,” J. Histochem. Cytochem. 33:77-79; Ross, R. D., Joneckis, C. C., Ordonez, J. V., Sisk, A. M., Wu, R. K., Hamburger, A. W., and Nora, R. E. (1989), “Estimation of cell survival by flow cytometric quantification of fluorescein diacetate/propidium iodide viable cell number,” Cancer Res. 49:3776-3782.
Calcein-AM, which is an acetoxylmethyl ester of calcein, is highly lipophilic and cell permeable. Calcein-AM in itself is not fluorescent, but the calcein generated by esterase in a viable cell emits a green fluorescence with an excitation wavelength of 490 nm and an emission of 515 nm. Therefore, Calcein-AM can only stain viable cells. See, e.g., Kimura, K., et al., Neurosci. Lett., 208, 53 (1998); Shimokawa, I., et al., J. Geronto., 51a, b49 (1998); Yoshida, S., et al., Clin. Nephrol., 49, 273 (1998); and Tominaga, H., et al., Anal. Commun., 36, 47 (1999).
Resazurin (also known as Alamar Blue) is a blue compound that can be reduced to pink resorufin which is fluorescent. This dye is mainly used in viability assays for mammalian cells. C12-resazurin has better cell permeability than resazurin. When lipophilic C12-resazurin crosses the cell membranes, it is subsequently reduced by living cells to make a red fluorescent resorufin. The adsorption/emission of C12-resazurin is 563/587 nm. See, e.g., Appl Environ Microbiol 56, 3785 (1990); J Dairy Res 57, 239 (1990); J Neurosci Methods 70, 195 (1996); J Immunol Methods 210, 25 (1997); J Immunol Methods 213, 157 (1998); Antimicrob Agents Chemother 41, 1004 (1997).

Examples of the reagent for selective lysis of eukaryotic cells include, but are not limited to, alkylglycosides, Brij 35 (C12E23 Polyoxyethyleneglycol dodecyl ether), Brij 58 (C16E20 Polyoxyethyleneglycol dodecyl ether), Genapol, glucanids such as MEGA-8, -9, -10, octylglucoside, Pluronic F127, Triton X-100 (C14H22O(C2H4O)n), Triton X-114 (C24H42O6), Tween 20 (Polysorbate 20) and Tween 80 (Polysorbate 80), Nonidet P40, deoxycholate, reduced Triton X-100 and/or Igepal CA 630. In some embodiments, the composition comprises a dye as described herein and deoxycholate (e.g., sodium deoxycholate) as a reagent for selective lysis of eukaryotic cells. In some embodiments, the composition comprises deoxycholate at a concentration selected from 0.0001% to 1 wt %. In some embodiments, the composition comprises deoxycholate at a concentration of 0.005 wt %. In some embodiments, the composition may comprise more than one reagent for selective lysis of eukaryotic cells.
In some embodiments, the composition may comprise two different reagents for selective lysis of eukaryotic cells. In some instances, when more than one selective lysis reagents are used, more effective and/or complete selective lysis of eukaryotic cells in a sample may be achieved. For example, the composition may comprise deoxycholate (e.g., sodium deoxycholate) and Triton X-100 as two different reagents for selective lysis of eukaryotic cells. In some embodiments, the composition comprises deoxycholate (e.g., sodium deoxycholate) at a concentration selected from 0.0001% to 1 wt % (e.g., 0.005 wt %) and Triton X-100 at a concentration selected from 0.1 to 0.05 wt %.
In some embodiments, after a sample (e.g., a biological sample) is treated or contacted with a composition comprising a dye and one or more reagents for selective lysis of eukaryotic cells as described herein, the eukaryotic cells (e.g., animal cells) in the sample are selectively lysed whereby a substantial percentage (e.g., more than 20%, 40%, 60%, 80%, 90% or even more that 95%) of the bacterial cells in the same sample remains intact or alive.
In some embodiments, the composition does not comprise a reagent for selective lysis of eukaryotic cells, and such a composition is useful for detecting or quantifying viable bacterial cells in a sample (e.g., an environmental sample such as a water sample) that does not contain any eukaryotic cells.
In some embodiments, the composition further comprises an electrolyte, such as a divalent electrolyte (e.g., MgCl2). In some embodiments, the composition comprises MgCl2 at a concentration selected from 0.1 mM to 100 mM (e.g., a concentration selected from 0.5 mM to 50 mM).

In some embodiments, the composition further comprises an anti-fungal agent. Suitable anti-fungal agents for use herein include, but are not limited to, fungicidal and fungistatic agents including terbinafine, itraconazole, micronazole nitrate, thiapendazole, tolnaftate, clotrimazole and griseofulvin. In some embodiments, the anti-fungal agent is a polyene anti-fungal agent, such as amphotericin-B, nystatin, and pimaricin.
In some embodiments, the composition does not contain any anti-fungal agent. In some embodiments, the composition contains broad spectrum antibiotics but not any anti-fungal agent. Such compositions that do not contain anti-fungal agents but contain broad spectrum antibiotics may be useful in detecting or quantifying fungi (e.g., yeast) in a sample.
In some embodiments, the composition does not contain any anti-fungal agent, any antibiotics or any anti-mammalian agent. Such compositions that do not selectively lyse mammalian cells may be useful in detecting or quantifying mammalian cells (e.g., cells from the GI tract) in a sample since many dyes have a higher affinity for mammalian as compared to bacteria or fungi cells. In some embodiments, the composition contains broad spectrum antibiotics and one or more anti-fungal agents. Such compositions that contain anti-fungal agents and broad spectrum antibiotics may be useful in detecting or quantifying mammalian cells (e.g., cells from the GI tract) in a sample. The detection or quantification of mammalian cells may be useful for determining cell turnover in a subject. High cell turnover is sometimes associated with a GI injury (e.g., lesion), the presence of a tumor(s), or radiation-induced colitis or radiation enteropathy.
In some embodiments, the composition further comprises an antibiotic agent as described herein. Such a composition may be useful in detecting or quantifying antibiotic-resistant strains of bacteria in a sample.
In certain embodiments, the composition comprises Triton X-100, deoxycholate, resazurin, and MgCl2. In some embodiments, the composition comprises Triton X-100, deoxycholate, resazurin, amphotericin-B and MgCl2. In some embodiments, the composition comprises 0.1 wt % or 0.05 wt % Triton X-100; 0.005 wt % deoxycholate; 10 mM resazurin; 2.5 mg/L amphotericin-B and 50 mM MgCl2. In some embodiments, the composition has a pH of 6.0.
In certain embodiments, the compositions are suitable for use in a kit or device, e.g., for detecting or quantifying viable bacterial cells in a sample. In some embodiments, such a device is an ingestible device for detecting or quantifying viable bacterial cells in vivo (e.g., in the GI tract).

Penetration of GI tissue by an IL-12/IL-23 inhibitor can be detected by administering a labeled antibody or labeled antigen-binding antibody fragment, and performing imaging on the subject (e.g., ultrasound, computed tomography, or magnetic resonance imaging). For example, the label can be a radioisotope, a heavy metal, a fluorophore, or a luminescent agent (e.g., any suitable radioisotopes, heavy metals, fluorophores, or luminescent agents used for imaging known in the art).
While not wishing to be bound to a particular theory, the inventors contemplate that at or near the site of release a concentration gradient of the IL-12/Il-23 inhibitor is generated in the mucosa, and that administration of an IL-12/IL-23 inhibitor using a device as described herein advantageously results in a “reverse” concentration gradient when compared to the concentration gradient resulting from systemic administration. In such “reverse” concentration gradient, the drug concentration is highest from superficial to deep with respect to the mucosal surface. Systemic administration instead typically results in concentrations of the drug being highest from deep to superficial. A “reverse” concentration gradient as described above aligns more favorably with the pathophysiology of IBD.
In some embodiments, administration of IL-12/IL-23 inhibitor can provide for treatment (e.g., a reduction in the number, severity, and/or duration of one or more symptoms of any of the disorders described herein in a subject) for a time period of between about 1 hour to about 30 days, about 1 hour to about 28 days, about 1 hour to about 26 days, about 1 hour to about 24 days, about 1 hour to

Exemplary methods for determining stool consistency score are described herein. Additional methods for determining a stool consistency score are known in the art.
In some embodiments, administration of an IL-12/IL-23 inhibitor using any of the devices or compositions described herein can result in a ratio of GI tissue concentration of the IL-12/IL-23 inhibitor to the blood, serum, or plasma concentration of the IL-12/IL-23 inhibitor that is higher than the same ratio when the IL-12/IL-23 inhibitor is administered by traditional means (e.g., systemically or orally). Examples of a ratio of GI tissue concentration of the IL-12/IL-23 inhibitor to the blood, serum, or plasma concentration of the IL-12/IL-23 inhibitor include about 2 to about 3000, about 2 to about

In certain embodiments, remission in the patient is determined to be induced when the Mayo Clinic Score <2 and no individual subscore >1, which is also referred to as clinical remission. In certain embodiments, mucosal healing is determined to have occurred when the patient is determined to have an endoscopy subscore of 0 or 1 as assessed by flexible sigmoidoscopy. In certain such embodiments, patients who experience mucosal healing are determined to have an endoscopy subscore of 0. In certain embodiments, clinical response is determined to have occurred when the patient experiences a 3-point decrease and 30% reduction from baseline in MCS and >1-point decrease in rectal bleeding subscore or absolute rectal bleeding score of 0 or 1.
In some embodiments, the method comprises identifying the disease site substantially at the same time as releasing the IL-12/IL-23 inhibitor.
In some embodiments, the method comprises monitoring the progress of the disease. In some embodiments, monitoring the progress of the disease comprises measuring the weight of the subject over a period of about 1-14 weeks, such as about 6-8 weeks following administration of the IL-12/IL-23 inhibitor, including at the 6-8 week time point, or over a period of about 52 weeks following administration of the IL-12/IL-23 inhibitor, including at the 52 week time point. In some embodiments, monitoring the progress of the disease comprises measuring the food intake of the subject; measuring the level of blood in the feces of the subject; measuring the level of abdominal pain of the subject; and/or a combination of the above, for example over a period of about 1-14 weeks, such as about 6-8 weeks following administration of the IL-12/IL-23 inhibitor, including at the 6-8 week time point, or over a period of about 52 weeks following administration of the IL-12/IL-23 inhibitor, including at the 52 week time point.
In some embodiments, the method comprises administering an IL-12/IL-23 inhibitor with a spray catheter. For example, administering an IL-12/IL-23 inhibitor with a spray catheter may be performed in step (e) hereinabove.
In some embodiments, the method does not comprise administering an IL-12/IL-23 inhibitor with a spray catheter.
In some embodiments, data obtained from cell culture assays and animal studies can be used in formulating an appropriate dosage of any given IL-12/IL-23 inhibitor. The effectiveness and dosing of any IL-12/IL-23 inhibitor can be determined by a health care professional or veterinary professional using methods known in the art, as well as by the observation of one or more disease symptoms in a subject (e.g., a human). Certain factors may influence the dosage and timing required to effectively treat a subject (e.g., the severity of the disease or disorder, previous treatments, the general health and/or age of the subject, and the presence of other diseases).
In some embodiments, the subject is further administered an additional therapeutic agent (e.g., any of the additional therapeutic agents described herein). The additional therapeutic agent can be administered to the subject at substantially the same time as the IL-12/IL-23 inhibitor or pharmaceutical composition comprising it is administered and/or at one or more other time points. In some embodiments, the additional therapeutic agent is formulated together with the IL-12/IL-23 inhibitor (e.g., using any of the examples of formulations described herein).
In some embodiments, the subject is administered a dose of the IL-12/IL-23 inhibitor at least once a month (e.g., at least twice a month, at least three times a month, at least four times a month, at least once a week, at least twice a week, three times a week, once a day, or twice a day). The IL-12/IL-23 inhibitor may be administered to a subject chronically. Chronic treatments include any form of repeated administration for an extended period of time, such as repeated administrations for one or more months, between a month and a year, one or more years, more than five years, more than 10 years, more than 15 years, more than 20 years, more than 25 years, more than 30 years, more than 35 years, more than 40 years, more than 45 years, or longer. Alternatively, or in addition, chronic treatments may be administered. Chronic treatments can involve regular administrations, for example one or more times a day, one or more times a week, or one or more times a month. For example, chronic treatment can include administration (e.g., intravenous administration) about every two weeks (e.g., between about every 10 to 18 days).
A suitable dose may be the amount that is the lowest dose effective to produce a desired therapeutic effect. Such an effective dose will generally depend upon the factors described herein. If desired, an effective daily dose of IL-12/IL-23 inhibitor can be administered as two, three, four, five, or six or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms.
In some examples, administration of an IL-12/IL-23 inhibitor using any of the compositions or devices described herein can result in the onset of treatment (e.g., a reduction in the number, severity, or duration of one or more symptoms and/or markers of any of the diseases described herein) or drug-target engagement in a subject within a time period of about 10 minutes to about 10 hours, about 10

Any of the foregoing biomarkers can be used as a biomarker for one or more of other conditions as appropriate.
In some embodiments of the methods herein, the methods comprise determining the time period of onset of treatment following administration of the device.
Colitis is experimentally induced to mice via the dextran sulfate sodium (DSS)-induced colitis model. This model is widely used because of its simplicity and many similarities with human ulcerative colitis. Briefly, mice are subjected to DSS via cecal catheterization, which is thought to be directly toxic to colonic epithelial cells of the basal crypts, for several days until colitis is induced.
Mice are allocated to one of seven cohorts, depending on the agent that is administered:
The control or agent is applied to a damaged mucosal surface of the bowel via administration through a cecal catheter at the dose levels described above.
Additionally, for each cohort, the animals are separated into two groups. One group receives a single dose of the control or agent on day 10 or 12. The other group receives daily (or similar) dosing of the control or agent.
For each animal, efficacy is determined (e.g., by endoscopy, histology, etc.), and cytotoxic T-cell levels are determined in blood, feces, and tissue (tissue levels are determined after animal sacrifice). For tissue samples, levels HER2 are additionally determined, and the level of cytotoxic T cells is normalized to the level of HER2. Additionally, other cytokine levels are determined in tissue (e.g., phospho STAT 1, STAT 3 and STAT 5), in plasma (e.g., VEGF, VCAM, ICAM, IL-6), or both.
Pharmacokinetics are determined both systemically (e.g., in the plasma) and locally (e.g., in colon tissue). For systemic pharmacokinetic analysis, blood and/or feces is collected from the animals at one or more timepoints after administration (e.g., plasma samples are collected at 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, and/or 8 hours after administration). Local/colon tissue samples are collected once after animal sacrifice.
Female swine weighing approximately 35 to 45 kg at study start are fasted at least 24 hours prior to intra-rectal administration of trinitrobenzene sulfonic acid (TNBS). Animals are lightly anesthetized during the dosing and endoscopy procedure. An enema to clean the colon is used, if necessary. One animal is administered 40 mL of 100% EtOH mixed with 5 grams of TNBS diluted in 10 mL of water via an enema using a ball-tipped catheter. The enema is deposited in the proximal portion of the descending colon just past the bend of the transverse colon. The TNBS is retained at the dose site for 12 minutes by use of two Foley catheters with 60-mL balloons placed in the mid-section of the descending colon below the dose site. A second animal is similarly treated, but with a solution containing 10 grams of TNBS. An Endoscope is employed to positively identify the dose site in both animals prior to TNBS administration. Dosing and endoscopy are performed by a veterinary surgeon.
Seven (7) days after TNBS administration, after light anesthesia, the dose site and mucosal tissues above and below the dose site are evaluated by the veterinary surgeon using an endoscope. Pinch Biopsies are obtained necessary, as determined by the surgeon. Based on the endoscopy findings, the animals may be euthanized for tissue collection on that day, or may proceed on study pending the results of subsequent endoscopy exams for 1 to 4 more days. Macroscopic and microscopic alterations of colonic architecture, possible necrosis, thickening of the colon, and substantial histologic changes are observed at the proper TNBS dose.
Clinical signs (e.g., ill health, behavioral changes, etc.) are recorded at least daily during acclimation and throughout the study. Additional pen-side observations are conducted twice daily (once-daily on weekends). Body weight is measured for both animals Days 1 and 7 (and on the day of euthanasia if after Day 7).
On the day of necropsy, the animals are euthanized via injection of a veterinarian-approved euthanasia solution. Immediately after euthanasia in order to avoid autolytic changes, colon tissues are collected, opened, rinsed with saline, and a detailed macroscopic examination of the colon is performed to identify macroscopic finings related to TNBS-damage. Photos are taken. Tissue samples are taken from the proximal, mid, and distal transverse colon; the dose site; the distal colon; the rectum; and the anal canal. Samples are placed into NBF and evaluated by a board certified veterinary pathologist.
Sixteen (16) swine (approximately 35 to 45 kg at study start) are allocated to one of five groups:
On Day 0, the test article is applied to a damaged mucosal surface of the bowel via intra-rectal administration or subcutaneous injection by a veterinary surgeon at the dose levels and volume described above.
Clinical observations are conducted at least once daily. Clinical signs (e.g., ill health, behavioral changes, etc.) are recorded on all appropriate animals at least daily prior to the initiation of experiment and throughout the study until termination. Additional clinical observations may be performed if deemed necessary. Animals whose health condition warrants further evaluation are examined by a Clinical Veterinarian. Body weight is measured for all animals Days −6, 0, and after the last blood collections.
Blood: Blood is collected (cephalic, jugular, and/or catheter) into EDTA tubes during acclimation on Day-7, just prior to dose on Day 0, and 0.5, 1, 2, 4, 6, 8, 12, 24, and 48 hours post-dose. The EDTA samples are split into two aliquots and one is centrifuged for pharmacokinetic plasma and either analyzed immediately, or stored frozen (−80° C.) for later pharmacokinetic analyses. The remaining sample of whole blood is used for pharmacodynamic analyses.
Feces: Feces is collected Day −7, 0 and 0.5, 1, 2, 4, 6, 8, 12, 24 and 48 hours post-dose, and either analyzed immediately, or flash-frozen on liquid nitrogen and stored frozen at −70° C. pending later analysis of drug levels and inflammatory cytokines.
Tissue: Immediately after euthanasia in order to avoid autolytic changes, colon tissues are collected, opened, rinsed with saline, and a detailed macroscopic examination of the colon is performed to identify macroscopic finings related to TNBS-damage. Triplicate samples of normal and damaged tissues are either analyzed immediately, or are flash-frozen on liquid nitrogen and stored frozen at −70° C. pending later analysis of drug concentration, inflammatory cytokines and histology.
Samples are analyzed for adalimumab levels (local mucosal tissue levels and systemic circulation levels), and for levels of inflammatory cytokines including TNF-alpha.
Animals are euthanized as per the schedule in Table 8, where one animal each of Vehicle and Treated Control groups is euthanized at 6 and 48 hours post-dose, and one animal of each the adalimumab groups are euthanized at 6, 12, 24 and 48 hours post-dose. Animals are discarded after the last blood collection unless retained for a subsequent study.
DSS-induced colitis Yorkshire-Cross Farm Swine (approximately 5-10 kg at study start) are allocated to one of five groups:
1. Vehicle Control: (saline); intra-rectal;
2. Treated Control: Adalimumab (13 mg in saline); subcutaneous;
3. Adalimumab: Adalimumab (13 mg in saline); intra-rectal.
At t=0, the test article is applied to a damaged mucosal surface of the bowel via intra-rectal administration or subcutaneous injection by a veterinary surgeon at the dose levels and volume described above.
Clinical signs (e.g., ill health, behavioral changes, etc.) are recorded on all appropriate animals at least daily prior to the initiation of experiment and throughout the study until termination. Additional clinical observations may be performed if deemed necessary. Animals whose health condition warrants further evaluation are examined by a Clinical Veterinarian.
Blood: Blood is collected (cephalic, jugular, and/or catheter) into EDTA tubes during acclimation on Day-7, just prior to dose on Day 0, and 12 hours post-dose. The EDTA samples are split into two aliquots and one is centrifuged for pharmacokinetic plasma and either analyzed immediately, or stored frozen (−80° C.) for later pharmacokinetic analyses. The remaining sample of whole blood is used for pharmacodynamic analyses.
Feces: Feces is collected Day −7, 0 and 12 hours post-dose, and either analyzed immediately, or flash-frozen on liquid nitrogen and stored frozen at −70° C. pending later analysis of drug levels and inflammatory cytokines.
Tissue: Immediately after euthanasia (12 hours after dosing) in order to avoid autolytic changes, colon tissues are collected, opened, rinsed with saline, and a detailed macroscopic examination of the colon is performed to identify macroscopic finings related to DSS-damage. Triplicate samples of normal and damaged tissues are either analyzed immediately, or are flash-frozen on liquid nitrogen and stored frozen at −70° C. pending later analysis of drug concentration, inflammatory cytokines and histology.
Samples are analyzed for adalimumab levels (local mucosal tissue levels and systemic circulation levels), and for levels of inflammatory cytokines including TNF-alpha.
Animals are euthanized at 12 hours post-dose.
The objective of this study was to compare the efficacy of an IL-12 inhibitor (anti-IL-12 p40; anti-p40 mAb; BioXCell (Cat#: BE0051)), when dosed systemically versus intracecally, to the treat dextran sulfate sodium salt (DSS)-induced colitis in male C57Bl/6 mice.
Normal male C57Bl/6 mice between the ages of 6-8 weeks old, weighing 20-24 g, were obtained from Charles River Laboratories. The mice were randomized into thirteen groups of twelve animals and two groups of eight animals, and housed in groups of 6-8 per cage, and acclimatized for at least three days prior to entering the study. Animal rooms were set to maintain a minimum of 12 to 15 air changes per hour, with an automatic timer for a light/dark cycle of 12 hours on/off, and fed with Labdiet 5053 sterile rodent chow, with water administered ad libitum.
Animals were placed under isoflurane anesthesia, with the cecum exposed via a midline incision in the abdomen. A small point incision was made in the distal cecum where 1-2 cm of the cannula was inserted. The incision was closed with a purse string suture using 5-0 silk. An incision was then made in the left abdominal wall through which the distal end of the cannula was inserted and pushed subcutaneously to the dorsal aspect of the back. The site was then washed copiously with warmed saline prior to closing the abdominal wall. A small incision was also made in the skin of the back between the shoulder blades, exposing the tip of the cannula. The cannula was secured in place using suture, wound clips, and tissue glue. All animals received 1 mL of warm sterile saline (subcutaneous injection) and were monitored closely until recovery before returning to their cage. All animals received 0.6 mg/kg BID buprenorphine for the first 3 days, and Baytril® at 10 mg/kg every day for the first 5 days post-surgery.
Colitis was induced in male C57Bl/6 mice by exposure to 3% DSS drinking water (MP Biomedicals #0260110) from Day 0 to Day 5. Fresh DSS/water solutions were made again on Day 3 and any of the remaining original DSS solution will be discarded.
All animals were weighed daily and visually assessed for the presence of diarrhea and/or bloody stool at the time of dosing. The mice underwent two video endoscopies, one on day 10 and one on day 14, to assess colitis severity. Images were captured from each animal at the most severe region of disease identified during the endoscopy, and assessed using the rubric demonstrated in Table 9. Additionally, stool consistency was scored during the endoscopy using this rubric (Table 10) (0=Normal, well-formed pellet, 1=Loose stool, soft, staying in shape, 2=Loose stool, abnormal form with excess moisture, 3=Watery or diarrhea, 4=Bloody diarrhea). At necropsy, intestinal contents, peripheral blood, and tissue, and cecum/colon contents were collected for analysis.
Mice were treated with anti-IL-12 p40 during the acute phase of colitis due to its efficacy in the treatment of DSS-induced colitis. The test article was dosed at a volume of 0.1 mL/20 g from days 0 to 14. Anti-IL-12 p40 was administered intraperitoneally at a dose of 10 mg/kg every 3 days, and intracecally at a dose of 10 mg/kg, either every 3 days or every day. There was also a lower dose of 1 mg/kg given every day intracecally. The control groups were not administered drugs, and the vehicles (sterile PBS) were administered the placebo drug intraperitoneally and intracecally every day. These drugs were given from days 5-14, which is 9 days of administration. A more detailed explanation of dosing and groups can be seen in Table 11.
Intestinal contents, peripheral blood, and tissue were collected at sacrifice on day 14, as follows: at the end of each study period, mice were euthanized by CO2 inhalation immediately following endoscopy on day 14. The blood was collected via cardiac puncture into K2EDTA-coated tubes and centrifuged at 4000×g for 10 minutes. The blood cell pellet was retained and snapped frozen. The resulting plasma was then split into two separate cryotubes, with 100 μL in one tube and the remainder in the second. Plasma and cell pellet were also collected, flash frozen, and stored at −80 degrees Celsius.
The cecum and colon were removed from each animal and contents were collected, weighed, and snap frozen in separate cryovials. The colon was excised, rinsed, measured, weighed, and then trimmed to 6 cm in length and divided into 5 pieces. The most proximal 1 cm of colon was snapped frozen for subsequent bioanalysis of test article levels. Of the remaining 5 cm of colon, the most distal and proximal 1.5-cm sections was placed in formalin for 24 hours then transferred to 70% ethanol for subsequent histological evaluation. The middle 2-cm portion was bisected longitudinally and placed into two separate cryotubes, weighed, and snap frozen in liquid nitrogen.

No significant differences in clinical observations or gastrointestinal-specific adverse effects, including stool consistency and/or bloody stool, were observed due to cannulation or intra-cecal treatments when compared with vehicle. No toxicity resulting from the treatments was reported. A significant reduction in body weight-loss (AUC) was found in groups treated with anti-IL-12 p40 antibody (10 mg/kg and 1 mg/kg, QD) via intra-cecal delivery when compared with vehicle control and intraperitoneal delivery (10 mg/kg, Q3D). The immunohistochemistry staining in anti-IL-12 p40 antibody (10 mg/kg, QD) treatment groups showed penetration of the antibody in all layers of colon tissue, including lumen mucosa, lamina propria, submucosa, tunica muscularis, via intra-cecal delivery. The distribution of anti-IL-12 p40 antibody was found in all segments of the colon, however, higher levels were detected in the proximal region. A significantly higher mean concentration of anti-IL-12 p40 antibody was found in the gastrointestinal contents and colon tissues when delivered via intra-cecal administration (Anti-p40: 10 mg/kg and 1 mg/kg, QD) compared with intraperitoneal administration (anti-p40: 10 mg/kg, Q3D). The blood level of anti-IL-12 p40 antibody was significantly higher when delivered via intraperitoneal administration (Q3D) as compared to intra-cecal administration (Q3D & QD). The concentrations of inflammatory cytokines, including IL-1β, IL-6, and IL-17, were significantly reduced by anti-IL-12 p40 antibody (10 mg/kg, QD) treatment when delivered via intra-cecal administration as compared to vehicle controls.
In sum, these data show that the compositions and devices provided herein can suppress the local immune response in the intestine, while having less of a suppressive effect on the systemic immune response of an animal. These data also suggest that the presently claimed compositions and devices will provide for treatment of colitis and other pro-inflammatory disorders of the intestine.
The objective of this study was to compare the efficacy of an integrin inhibitor (anti-integrin α4β7; anti-LPAM1; DATK-32 mAb; BioXCell (Cat#: BE0034)) when dosed systemically versus intracecally for treating dextran sulfate sodium salt (DSS)-induced colitis in male C57Bl/6 mice.
Normal male C57Bl/6 mice between the ages of 6-8 weeks old, weighing 20-24 g, were obtained from Charles River Laboratories. The mice were randomized into thirteen groups of twelve animals and two groups of eight animals, and housed in groups of 6-8 per cage, and acclimatized for at least three days prior to entering the study.

At necropsy, intestinal contents, peripheral blood and tissue, and cecum/colon contents were collected for analysis.
Mice were treated with DATK32 during the acute phase of colitis due to its efficacy in the treatment of DSS-induced colitis. The test article was dosed at a volume of 0.1 mL/20 g from days 0 to 14. DATK32 was administered intraperitoneally at a dose of 25 mg/kg every 3 days, and intracecally at a dose of 25 mg/kg, either every 3 days or every day. There was also a lower dose of 5 mg/kg given every day intracecally. The control groups were not administered drugs, and the vehicle (sterile PBS) was administered as the placebo drug intraperitoneally and intracecally every day. These drugs were given from days 5-14, which is 9 days of administration. A more detailed explanation of dosing and groups can be seen in Table 14.
Intestinal contents, peripheral blood, and tissue were collected at sacrifice on day 14, as follows: at the end of each study period, mice were euthanized by CO2 inhalation immediately following endoscopy on day 14. The blood was collected via cardiac puncture into K2EDTA-coated tubes and centrifuged at 4000×g for 10 minutes. The blood cell pellet was retained and snapped frozen. The resulting plasma was then split into two separate cryotubes, with 100 μL in one tube and the remainder in the second. Plasma and the cell pellet were also collected, flash frozen, and stored at −80 degrees Celsius. An ELISA was used to determine the level of rat IgG2A.
The cecum and colon were removed from each animal and contents were collected, weighed, and snap frozen in separate cryovials. The colon was excised, rinsed, measured, weighed, and then trimmed to 6 cm in length and divided into 5 pieces. The most proximal 1 cm of colon was snapped frozen for subsequent bioanalysis of anti-DATK32 levels. Of the remaining 5 cm of colon, the most distal and proximal 1.5-cm sections was placed in formalin for 24 hours then transferred to 70% ethanol for subsequent histological evaluation. The middle 2-cm portion was bisected longitudinally and placed into two separate cryotubes, weighed, and snap frozen in liquid nitrogen.
There was an additional collection of 100 μL of whole blood from all animals and processed for FACS analysis of α4 and β7 expression on T-helper memory cells. Tissue and blood were immediately placed in FACS buffer (1×PBS containing 2.5% fetal calf serum) and analyzed using the following antibody panel (Table 15).

No significant differences in clinical observations or gastrointestinal-specific adverse effects, including stool consistency and/or bloody stool, were observed due to cannulation or intra-cecal treatments when compared with vehicle. No toxicity resulting from the treatments was reported. A significant reduction in body weight-loss was also found with DATK32 (5 mg/kg, QD) treatment (IC) when compared to vehicle control at the endpoint (day 14). The immunohistochemistry staining in DATK32 (25 mg/kg, QD) treatment groups showed penetration of DATK32 in all layers of colon tissue, including lumen mucosa, lamina propria, submucosa, tunica muscularis, via intra-cecal delivery. The distribution of DATK32 was found in all segments of the colon, however, higher levels were detected in the proximal region. A significantly higher mean concentration of DATK32 was found in gastrointestinal contents and colon tissues when delivered via intra-cecal administration (DATK32: 25 mg/kg and 5 mg/kg, QD) as compared to intraperitoneal administration (DATK32: 25 mg/kg, Q3D). The blood level of DATK32 was significantly higher when delivered via intraperitoneal administration (Q3D) as compared to intra-cecal administration (Q3D & QD). The pharmacokinetics of DATK32 (25 mg/kg, QD) showed significantly higher mean concentrations of DATK32 when delivered via intra-cecal administration at 1, 2, and 4 h post-dose in the gastrointestinal contents, and 1, 2, 4 and 24 h in colon tissue as compared with the mean concentrations of DATK32 following intraperitoneal administration. The mean number of gut-homing T cells (Th memory cells) was significantly higher in the blood of groups treated with DATK32 via intra-cecal administration (QD 25 mg/kg and QD 5 mg/kg) as compared to the groups treated with DATK32 via intraperitoneal administration (Q3D 25 mg/kg). The mean number of Th memory cells was significantly lower in the Peyer's Patches of groups treated with DATK32 via intra-cecal administration (QD 25 mg/kg and 5 mg/kg) as compared to the groups treated with DATK32 via intraperitoneal administration (Q3D 25 mg/kg). The mean number of Th memory cells in mesenteric lymph nodes (MLN) was significantly lower in groups treated with DATK32 via intra-cecal administration (QD and Q3D 25 mg/kg and QD 5 mg/kg) as compared to the groups treated with DATK32 via intraperitoneal administration (Q3D 25 mg/kg).
In sum, these data show that the compositions and devices provided herein can suppress the local immune response in the intestine, while having less of a suppressive effect on the systemic immune response of an animal. These data also show that the release of DATK-32 antibody in the colon can result in a suppression of leukocyte recruitment and may provide for the treatment of colitis and other pro-inflammatory diseases of the intestine.
The objective of this study is to assess DATK32 bio-distribution when dosed intracecally in male C57Bl/6 mice. A minimum of 10 days prior to the start of the experiment a cohort of animals will undergo surgical implantation of a cecal cannula. A sufficient number of animals will undergo implantation to allow for 24 cannulated animals to be enrolled in the main study (e.g., 31 animals). Animals were dosed with vehicle or test article via intracecal injection (IC) on Day 0 as indicated in Table 16. Animals from all groups were sacrificed for terminal sample collection three hours following test article administration.
Normal male C57Bl/6 mice between the ages of 6-8 weeks old, weighing 20-24 g, were obtained from Charles River Laboratories. The mice were randomized into two groups of twelve animals, and housed in groups of 12 per cage, and acclimatized for at least three days prior to entering the study. Animal rooms were set to maintain a minimum of 12 to 15 air changes per hour, with an automatic timer for a light/dark cycle of 12 hours on/off, and fed with Labdiet 5053 sterile rodent chow, with water administered ad libitum.
The animals were placed under isoflurane anesthesia, with the cecum exposed via a midline incision in the abdomen. A small point incision was made in the distal cecum where 1-2 cm of the cannula was inserted. The incision was closed with a purse string suture using 5-0 silk. An incision was then made in the left abdominal wall through which the distal end of the cannula was inserted and pushed subcutaneously to the dorsal aspect of the back. The site was then washed copiously with warmed saline prior to closing the abdominal wall. A small incision was also made in the skin of the back between the shoulder blades, exposing the tip of the cannula. The cannula was secured in place using suture, wound clips, and tissue glue. All animals received 1 mL of warm sterile saline (subcutaneous injection) and were monitored closely until recovery before returning to their cage. All animals received 0.6 mg/kg BID buprenorphine for the first 3 days, and Baytril® at 10 mg/kg every day for the first 5 days post-surgery.
Animals were dosed IC at a volume of 0.075 mL/animal on Days 0 as indicated in Table 16.
All animals were euthanized by CO2 inhalation three hours after dosing on Day 0.
Terminal blood was collected and prepared for plasma using K2EDTA as the anti-coagulant. The plasma will be split into two cryotubes, with 50 μL in one tube (PK analysis) and the remainder in another (other). Both samples were flash-frozen in liquid nitrogen. Plasma was stored at −80° C. for downstream analysis. Mesenteric lymph nodes (mLN) were collected, weighed, and flash-frozen in liquid nitrogen. Mesenteric lymph nodes were stored at −80° C. for downstream analysis. The small intestine was excised and rinsed, and the most distal 1 cm of ilium was dissected, weighed, and flash-frozen in liquid nitrogen. The samples were stored at −80° C. for downstream analysis. The cecum and colon were removed from each animal and contents collected, weighed, and snap frozen in separate cryovials. The samples were stored at −80° C. for downstream analysis. The colon was rinsed, and the most proximal 1 cm of colon was weighed and flash-frozen in liquid nitrogen. The snap frozen tissues were stored at −80° C.
The data in
The purpose of this non-Good Laboratory Practice (GLP) study was to explore the PK/PD, and bioavailability of adalimumab when applied to a TNBS-damaged mucosal surface (induced colitis) in Yorkshire-Cross farm swine, and to determine an appropriate dose and frequency for studies where a drug will be delivered by the ingestible device system. The ingestible device system will be capable of delivering a TNF inhibitor (adalimumab) topically and locally to damaged mucosa in human patients with inflammatory bowel disease (IBD). The TNBS-induced colitis model was validated when a single administration on Day 1 of 40 mL of 100% ethanol (EtOH) mixed with 5 grams of TNBS diluted in 10 mL of water via an enema using a rubber catheter resulted in the intended reproducible induction of damaged mucosal surface (induced colitis) in Yorkshire-Cross farm swine.
This study investigated whether topical delivery of adalimumab would result in increased local mucosal tissue levels with limited drug reaching systemic circulation, as compared to subcutaneous administration; whether local mucosal tissue levels of drug would be greater in damaged tissues when compared to normal tissues; whether increasing the dose of drug would result in increased mucosal tissue levels in local and distal TNBS-damaged tissues; and whether topical delivery of adalimumab would result in reductions in inflammatory cytokines such as TNF-α in damaged tissues, feces, and possibly blood.
All animals were subjected to intra-rectal administration of trinitrobenzene sulfonic acid (TNBS) to induce chronic colitis on day −2. All animals were fasted prior to colitis induction. Bedding was removed and replaced with rubber mats on day −3 to prevent ingestion of straw bedding material. The dose was 40 mL of 100% EtOH mixed with 5 grams of TNBS diluted in 10 mL of water, then instilled into the colon intra-rectally using a flexible gavage tube by a veterinary surgeon (deposited in a 10-cm portion of the distal colon and proximal rectum, and retained for 12 minutes by use of two Foley catheters with 60-mL balloons). Approximately 3 days after induction, macroscopic and microscopic alterations of colonic architecture were apparent: some necrosis, thickening of the colon, and substantial histologic changes were observed (
Adalimumab (EXEMPTIA™) is a Tumor Necrosis Factor (TNF) inhibitor. A single dose was pre-filled in a syringe (40 mg in a volume of 0.8 mL).
While subcutaneously administered adalimumab was detected at all times points tested in plasma, topically administered adalimumab was barely detectable in plasma (
Either subcutaneous or intra-rectal administration of adalimumab was well tolerated and did not result in death, morbidity, adverse clinical observations, or body weight changes. A decreased level of total TNBS-related inflammatory response was observed by adalimumab treatment via intra-rectal administration when applied to the damaged mucosal surface of the bowel when compared to subcutaneous delivery. A significantly higher concentration of adalimumab was measured in blood following subcutaneous delivery as compared to the blood concentration following intra-rectal administration. Intra-rectal administration of adalimumab decreased the total and normalized TNFα concentration over time (6-48h) and was more effective at reducing TNFα at the endpoint (48h) as compared to groups administered adalimumab subcutaneously.
In sum, these data show that the compositions and devices provided herein can suppress the local immune response in the intestine, while having less of a suppressive effect on the systemic immune response of an animal. For example, these data show that intracecal administration of adalimumab using a device as described herein can provide for local delivery of adalimumab to the site of disease, without suppressing the systemic immune response. These data also show that local administration of adalimumab using a device as described herein can result in a significant reduction of the levels of TNFα in diseases animals.
The objective of this study was to compare the efficacy of an immunosuppressant agent (cyclosporin A; CsA) when dosed systemically versus intracecally to treat dextran sulfate sodium salt (DSS)-induced colitis in male C57Bl/6 mice.
A minimum of 10 days prior to the start of the experiment a cohort of animals underwent surgical implantation of a cecal cannula. A sufficient number of animals underwent implantation to allow for 44 cannulated animals to be enrolled in the main study (e.g., 76 animals). Colitis was induced in 60 male C5Bl/6 mice by exposure to 3% DSS-treated drinking water from day 0 to day 5. Two groups of eight additional animals (cannulated and non-cannulated) served as no-disease controls (Groups 1 and 2). Animals were dosed with cyclosporin A via intraperitoneal injection (IP), oral gavage (PO), or intracecal injection (IC) from day 0 to 14 as indicated in Table 18. All animals were weighed daily and assessed visually for the presence of diarrhea and/or bloody stool at the time of dosing. Mice underwent video endoscopy on days 10 and 14 to assess colitis severity. Images were captured from each animal at the most severe region of disease identified during endoscopy. Additionally, stool consistency was scored during endoscopy using the parameters defined in Table 19. Following endoscopy on day 14, animals from all groups were sacrificed and underwent terminal sample collection.
Specifically, animals in all treatment groups dosed on day 14 were sacrificed at a pre-dosing time point, or 1, 2, and 4 hours after dosing (n=3/group/time point). Terminal blood was collected via cardiac puncture and prepared for plasma using K2EDTA as the anti-coagulant. The blood cell pellet was retained and snap frozen while the resulting plasma was split into two separate cryotubes, with 100 μL in one tube and the remainder in the second. Additionally, the cecum and colon were removed from all animals; the contents were collected, weighed, and snap frozen in separate cyrovials. The colon was then rinsed, measured, weighed, and then trimmed to 6 cm in length and divided into five pieces. The most proximal 1 cm of colon was snap frozen for subsequent bioanalysis of cyclosporin A levels. Of the remaining 5 cm of colon, the most distal and proximal 1.5-cm sections were each placed in formalin for 24 hours, then transferred to 70% ethanol for subsequent histological evaluation. The middle 2-cm portion was bisected longitudinally and placed into two separate cryotubes, weighed, and snap frozen in liquid nitrogen. All plasma and frozen colon tissue were stored at −80° C. for selected end point analysis. For all control animals in Groups 1-4, there was an additional collection of 100 μL of whole blood from all animals which was then processed for FACS analysis of α4 and β7 expression on Th memory cells. The details of the study are shown in Table 18.
Animals were placed under isoflurane anesthesia, and the cecum exposed via a mid-line incision in the abdomen. A small point incision was made in the distal cecum through which 1-2 cm of the cannula was inserted. The incision was closed with a purse-string suture using 5-0 silk. An incision was made in the left abdominal wall through which the distal end of the cannula was inserted and pushed subcutaneously to the dorsal aspect of the back. The site was washed copiously with warmed saline prior to closing the abdominal wall. A small incision was made in the skin of the back between the shoulder blades, exposing the tip of the cannula. The cannula was secured in place using suture, wound clips, and tissue glue. All animals received 1 mL of warm sterile saline (subcutaneous injection) and were monitored closely until fully recovered before returning to the cage. All animals received buprenorphine at 0.6 mg/kg BID for the first 3 days, and Baytril® at 10 mg/kg QD for the first 5 days following surgery.
Colitis was induced on day 0 via addition of 3% DSS (MP Biomedicals, Cat #0260110) to the drinking water. Fresh DSS/water solutions were made on day 3 and any of the remaining original DSS solution was discarded.
Animals were dosed by oral gavage (PO), intraperitoneal injection (IP), or intracecal injection (IC) at a volume of 0.1 mL/20 g on days 0 to 14 as indicated in Table 18.
Animals were observed daily (weight, morbidity, survival, presence of diarrhea, and/or bloody stool) in order to assess possible differences among treatment groups and/or possible toxicity resulting from the treatments.
Animals were monitored on a daily basis and those exhibiting weight loss greater than 30% were euthanized, and samples were not collected from these animals.
Each mouse underwent video endoscopy on days 10 and 14 using a small animal endoscope (Karl Storz Endoskope, Germany) under isoflurane anesthesia. During each endoscopic procedure still images as well as video were recorded to evaluate the extent of colitis and the response to treatment. Additionally, we attempted to capture an image from each animal at the most severe region of disease identified during endoscopy. Colitis severity was scored using a 0-4 scale (0=normal; 1=loss of vascularity; 2=loss of vascularity and friability; 3=friability and erosions; 4=ulcerations and bleeding). Additionally, stool consistency was scored during endoscopy using the parameters defined in Table 19.
Tissue and blood were immediately placed in FACS buffer (1× phosphate-buffered saline (PBS) containing 2.5% fetal calf serum (FCS)) and analyzed using the antibody panel in Table 20.

In sum, these data show that the compositions and devices provided herein can suppress the local immune response in the intestine, while having less of a suppressive effect on the systemic immune response of an animal. For example, these data demonstrate that the present compositions and devices can be used to release cyclosporin A to the intestine and that this results in a selective immune suppression in the colon, while having less of an effect on the immune system outside of the intestine. These data also suggest that the present compositions and devices will provide for the treatment of colitis and other pro-inflammatory disorders of the intestine.
Experiments were run to evaluate the effects that bellows material would have on the function of a drug used as the dispensable substance. The experiments also evaluated the effects on drug function due to shelf life in the bellows.
The adalimumab was loaded into simulated device jigs containing either tapered silicone bellows or smooth PVC bellows and allowed to incubate for 4, 24, or 336 hours at room temperature while protected from light.
The drug was subsequently extracted using the respective dispensing systems and tested by a competitive inhibition assay. The test method has been developed from the literature (Velayudhan et al., “Demonstration of functional similarity of proposed biosimilar ABP501 to adalimumab,” BioDrugs 30:339-351 (2016) and Barbeauet et al., “Application Note: Screening for inhibitors of TNFα/s TNFR1 Binding using AlphaScreen™ Technology,” PerkinElmer Technical Note ASC-016 (2002)), as well as pre-testing development work using control drug and experiments using the provided AlphaLISA test kits.
The bellows were loaded as follows: aseptically wiped the dispensing port of the simulated ingestible device jig with 70% ethanol; allowed to air dry for one minute; used an adalimumab delivery syringe to load each set of bellows with 200 μL of drug; took a photo of the loaded device; gently rotated the device such that the drug is allowed to come in contact with all bellows surfaces; protected the bellows from light; and incubate at room temperature for the predetermined time period to allow full contact of the drug with all bellows' surfaces.
The drug was extracted as follows: after completion of the incubation period; the device jig was inverted such that the dispensing port was positioned over a sterile collection microfuge tube and petri dish below; five cubic centimeters of air was drawn into an appropriate syringe; the lure lock was attached to the device jig; the syringe was used to gently apply positive pressure to the bellow with air such that the drug was recovered in the collection microfuge tube; where possible, a video of drug dispensing was taken; samples were collected from each bellows type; a control drug sample was collected by directly dispensing 200 μL of drug from the commercial dispensing syringe into a sterile microfuge tube; the control drug-free sample was collected by directly dispensing 200 μL of PBS using a sterile pipette into a sterile microfuge tube; the collected drug was protected from light; and the drug was diluted over the following dilution range (250, 125, 25, 2.5, 0.25, 0.025, 0.0125, 0.0025 μg) in sterile PBS to determine the IC50 range of the drug.
To determine any effects storage conditions may have on drug efficacy in the device, the drug (stored either in the syringe, silicon bellows, PVC bellows) was stored at room temperature while protected from light for 24 hours and 72 hours. Samples were then extracted and the steps in the preceding paragraph were repeated.
The AlphaLISA (LOCI™) test method was used. Human TNFα standard dilution ranges were prepared as described in Table 21.
The test was performed as follows: the above standard dilution ranges were in a separate 96-well plate; to ensure consistent mixing, samples were mixed up and down gently with a pipette five times; a 384-well test plate was prepared according to the test layout diagram depicted Table 22; five microliters of 10,000 pg/mL TNFα standard from the previously made dilution plate was added to each corresponding concentration as shown in Table 21; five microliters of recovered drug (directly from the commercial syringe (A), from the silicone bellows (B Si), from the PVC bellows (B PVC), or from the PBS control (C) was added into the corresponding wells described in Table 21; the test plate was incubated for one hour at room temperature while protected from light; 10 microliters of acceptor beads were added to each previously accessed well; the wells were incubated for 30 minutes at room temperature while protected from light; 10 μL of biotinylated antibody was added to each previously accessed well; the wells were incubated for 15 minutes at room temperature, while protected from light; the room lights were darkened and 25 microliters of streptavidin (SA) donor beads were added to each previously accessed well; the wells were incubated for 30 minutes at room temperature while protected from light; the plate was read in Alpha Mode; and the results were recorded. Upon addition of reagent(s) in the various steps, each well was pipetted up and down three times to achieve good mixing.

The objective of this study was to compare the efficacy of novel test articles, e.g., fluorescent SMAD7 antisense oligonucleotides (SMAD7 AS), when dosed systemically versus intracecally in the treatment of DSS-induced colitis, in male C57Bl/6 mice.
A minimum of 10 days prior to the start of the experiment a cohort of animals underwent surgical implantation of a cecal cannula. A sufficient number of animals underwent implantation to allow for 12 cannulated animals to be enrolled in the main study (i.e., 16 animals).
Colitis was induced in 12 male C57Bl/6 mice (Groups 4-5) by exposure to 3% DSS-treated drinking water from Day 0 to Day 5. Three groups of six additional animals per group (n=6 cannulated; n=12 non-cannulated; Groups 1-3) served as no-disease controls (Groups 1-3). All animals were weighed daily and assessed visually for the presence of diarrhea and/or bloody stool during this time.
Animals were dosed with test-article via oral gavage (PO) or intracecal injection (IC) once on Day 9 as indicated in Table 27. The animals in Group 0 were not dosed. The animals in Groups 2 and 4 were dosed PO with SMAD7 antisense. The animals in Groups 3 and 5 were dosed IC with SMAD7 antisense.
All animals were euthanized by CO2 inhalation 12 hours after dosing, on Day 10. Terminal blood was collected into two K2EDTA tubes and processed for plasma. Both plasma and pellet samples were snap-frozen in liquid nitrogen and stored at −80° C. Cecum contents were removed and the contents were split into two aliquots. Both aliquots were weighed and snap frozen in separate cryovials in liquid nitrogen. The cecum was excised and bisected longitudinally; each piece is separately weighed and flash-frozen in liquid nitrogen. The colon contents were removed and the contents were split into two aliquots. Both aliquots were weighed and snap frozen in separate cryovials in liquid nitrogen. The colon was then rinsed, and the most proximal 2 cm of colon was collected. This 2-cm portion was bisected longitudinally; each piece was separately weighed and flash-frozen in liquid nitrogen. Snap-frozen blood pellet, cecum/colon contents, and tissue samples were used for downstream fluorimetry or RP-HPLC. The details of the study design are shown in Table 27.
Normal male C57Bl/6 mice between the ages of 6-8 weeks old, weighing 20-24 g, were obtained from Charles River Laboratories. The mice were randomized into five groups of six mice each, and housed in groups of 8-15 per cage, and acclimatized for at least three days prior to entering the study. Animal rooms were set to maintain a minimum of 12 to 15 air changes per hour, with an automatic timer for a light/dark cycle of 12 hours on/off, and fed with Labdiet 5053 sterile rodent chow, with water administered ad libitum.
The animals were placed under isoflurane anesthesia, with the cecum exposed via a midline incision in the abdomen. A small point incision was made in the distal cecum, where 1-2 cm of the cannula was inserted. The incision was closed with a purse string suture using 5-0 silk. An incision was then made in the left abdominal wall through which the distal end of the cannula was inserted and pushed subcutaneously to the dorsal aspect of the back. The site was then washed copiously with warmed saline prior to closing the abdominal wall. A small incision was also made in the skin of the back between the shoulder blades, exposing the tip of the cannula. The cannula was secured in place using suture, wound clips, and tissue glue. All animals were administered 1 mL of warm sterile saline (subcutaneous injection) and were monitored closely until recovery before returning to their cage. All animals were administered 0.6 mg/kg BID buprenorphine for the first 3 days, and Baytril® at 10 mg/kg every day for the first 5 days post-surgery.
Colitis was induced on Day 0 via addition of 3% DSS (MP Biomedicals, Cat #0260110) to the drinking water. Fresh DSS/water solutions was provided on Day 3 and any of the remaining original DSS solution is discarded.
Animals were observed daily (weight, morbidity, survival, presence of diarrhea and/or bloody stool) in order to assess possible differences among treatment groups and/or possible toxicity resulting from the treatments.
Animals were monitored on a daily basis. Animals exhibiting weight loss greater than 30% were euthanized, and samples were not collected from these animals.
Animals were dosed with test-article via oral gavage (PO) or intracecal injection (IC) once on Day 9 as indicated in Table 27. Animals in Group 0 were not dosed. Animals in Groups 2 and 4 were dosed PO with SMAD7 antisense. Animals in Groups 3 and 5 were dosed IC with SMAD7 antisense.
All animals were euthanized by CO2 inhalation 12 hours after dosing, on Day 10.
Intestinal contents, peripheral blood and tissue were collected at sacrifice on Day 10, as follows:
Blood/Plasma: Terminal blood was collected into two K2EDTA tubes and processed for plasma. The approximate volume of each blood sample was recorded prior to centrifugation. Both plasma and pellet samples were snap-frozen in liquid nitrogen and stored at −80° C. The first pellet sample (sample 1) was used for fluorimetry. The second pellet sample (sample 2) was used for RP-HPLC.
Cecum Contents: Cecum contents was removed and contents were split into two aliquots. Both aliquots were weighed and snap frozen in separate cryovials in liquid nitrogen. The first sample (sample 1) was used for fluorimetry. The second sample (sample 2) was used for RP-HPLC.
Cecum: The cecum was excised and bisected longitudinally; each piece was separately weighed and snap-frozen. The first sample (sample 1) was used for fluorimetry. The second sample (sample 2) was used for RP-HPLC.
Colon Contents: Colon contents were removed and contents were split into two aliquots. Both aliquots were weighed and snap frozen in separate cryovials in liquid nitrogen. The first sample (sample 1) was used for fluorimetry. The second sample (sample 2) was used for RP-HPLC.
Colon: The colon was rinsed, and the most proximal 2 cm of colon was collected and bisected longitudinally. Each piece was separately weighed and flash-frozen in liquid nitrogen. The first sample (sample 1) was used for fluorimetry. The second sample (sample 2) was used for RP-HPLC.
SMAD7 Antisense Bioanalysis
Samples flash-frozen for fluorimetry were homogenized in 0.5 mL buffer RLT+(Qiagen). Homogenate was centrifuged (4000×g; 10 minutes), and supernatant was collected. Forty microliters of the sample was diluted 1:6 in 200 μL of bicarbonate solution and 100 μL of diluted supernatant was analyzed on a fluorescent plate reader (485 excitation; 535 emission) in duplicate.
Prior to the above, assay development was performed as follows. Samples (as indicated in Sample Collection) were harvested from a naïve animal and flash-frozen. Samples were then homogenized in 0.5 mL buffer RLT+, homogenate was centrifuged (4000×g; 10 minutes) and supernatant was collected and diluted 1:6 with bicarbonate solution (i.e., 0.5 mL supernatant was added to 2.5 mL of PBS). An aliquot (0.200 mL (90 μL for each duplicate) of each diluted sample was pipetted into 15 (14 dilution of FAM-AS-SAMD7+ blank control) Eppendorf tubes. One tube was set-aside to be used as a blank sample. Ten microliters of fluorescently-labeled SMAD7 antisense was then spiked into all other sample to achieve final concentrations of 50 μg/mL, 16.67 μg/mL, 5.56 μg/mL, 1.85 μg/mL, 0.62 μg/mL, 0.21 μg/mL, 0.069 μg/mL, 0.023 μg/mL, 7.6 ng/mL, 2.5 ng/mL, 0.847 ng/mL, 0.282 ng/mL, 0.094 ng/mL, and 0.024 ng/mL respectively. The fluorescently-labeled SMAD7 antisense was prepared and serially diluted such that the volume added to each organ homogenate sample was the same for each of the above concentrations. These samples were analyzed on a fluorescent plate reader (485 excitation; 535 emission) in duplicate.
Samples flash-frozen for RP-HPLC were homogenized in buffer RLT+(Qiagen). Homogenate was centrifuged (4000×g; 10 minutes), and supernatant was used to perform RP-HPLC analysis.
The data in
No significant differences were observed in clinical observations, GI-specific adverse effects or toxicity due to FAM-AS-SMAD7 treatment via PO vs IC. No fluorescent detection of FAM-AS-SMAD7 was found in plasma and whole blood cell pellets across all treatment groups. A significant higher fluorescent signal (RFU) of FAM-AS-SMAD7 was found in cecum tissue when delivered intra-cecally compared with PO in both normal and DSS-induced models (
The primary objective of this study was to compare the tissue, plasma, rectal sample, and GI content pharmacokinetics of tacrolimus through oral versus intra-cecal ingestible device delivery in normal Yorkshire-Cross farm swine.
This study compares the effects of administration of: a single intra-cecal administration of an ingestible device containing 0.8 mL sterile vehicle solution (80% alcohol, 20% castor oil (HCO-60)); a single oral dose of tacrolimus at 4 mg/0.8 mL (in sterile vehicle solution); and a single intra-cecal administration of an ingestible device containing either 1 mg/0.8 mL (in sterile vehicle solution), 2 mg/0.8 mL (in sterile vehicle solution), or 4 mg/0.8 mL (in sterile vehicle solution).
This study employed five groups of three female swine weighing approximately 45 to 50 kg at study start. Swine were randomly placed into animal rooms/pens as they are transferred from the delivery vehicle without regard to group. Group numbers were assigned to the rooms in order of room number. No further randomization procedure was employed. The study design is provided in Table 28.

Animals in Group 1 received an ingestible device containing 0.8 mL of vehicle solution (80% alcohol, 20% HCO-60). Animals in Group 2 received orally 4 mL liquid formulation of tacrolimus at 4 mg/0.8 mL per animal (Prograf: 5 mg/mL). Animals in Group 3 received intra-cecally an ingestible device containing tacrolimus at 1 mg in 0.8 mL per ingestible device. Animals in Group 4 received intra-cecally an ingestible device containing tacrolimus at 2 mg in 0.8 mL per ingestible device. Animals in Group 5 received intra-cecally an ingestible device containing tacrolimus at 4 mg in 0.8 mL per ingestible device. To control for potential confounding effects of the surgery, all groups fast on Day −11 at least 24 hr before being subjected to anesthesia followed by surgical placements of a cecal port by a veterinary surgeon at Day −10. All animals were fasted for at least 12 hr prior to dosing on Day 1. Animals were dosed via either intra-cecal dosing (IC) or oral dosing (PO) at Day 1 (between 6-8 μm.). All animals resumed feeding at approximately 4 hours after dose (11-12 μm. after dosing).
Animals in Group 1 (Vehicle Control) were administered a single intra-cecal ingestible device containing 0.8 mL Vehicle solution (80% alcohol, 20% castor oil (HCO-60) on Day 1. On Day −10 the animals were anesthetized, and a veterinary surgeon surgically placed an intra-cecal port in each animal. On Day 1, each animal was placed into a sling then a single intra-cecal ingestible device containing 0.8 mL vehicle solution (80% alcohol, 20% castor oil (HCO-60)) is introduced by the veterinary surgeon into the cecum via the cecal port in each animal. Following ingestible device placement, the animals were removed from the slings and placed back into their pens with water. All animals resumed feeding at approximately 4 hours after dose. Samples of rectal contents were collected for pharmacokinetic analyses from each animal at each of 1, 3, 6, and 12 hours post-ingestible device placement using a fecal swab (rectal swab). A total of 60 samples were collected.
Approximately 200˜400 mg of rectal content were collected, if available, with a fecal swab (Copan Diagnostics Nylon Flocked Dry Swabs, 502CS01). The fecal swab was pre-weighed and weighed after collection in the collection tube (Sterile Tube and Cap No Media, PFPM913S), and the sample weight was recorded. The fecal swab was broken via the breakpoint, and was stored in the collection tube, and immediately frozen at −70° C. Whole blood (2 mL) was collected into K2EDTA coated tubes for pharmacokinetics at each time-point of pre-dose and 1, 2, 3, 4, 6 and 12 hours post-dose. Immediately following euthanasia, tissue was collected. A total of 105 samples were collected.
For tissue necropsy, small intestine fluid and cecal fluid were collected separately from all the animals into two separate square plastic bottles, and stored at −20° C. The length and diameter of the cecum and the colon was measured from one animal in each group and recorded for reference. Tissues were collected for pharmacokinetic analyses and include mesenteric lymph nodes, a Peyer's Patch, and five gastrointestinal sections, including cecum, proximal colon, transverse colon, distal colon, and rectum. All samples were weighed, and the tissue sample weights were recorded. In each of the five gastrointestinal sections, tissue samples were collected in three different areas where the mucosal surface was visible and not covered by luminal content by using an 8.0-mm punch biopsy tool. Around 3 grams of the total punched sample were collected into a pre-weighed 15-mL conical tube, and the tissue weight was recorded. Three mesenteric lymph nodes were collected from different areas and weighed. At least one Peyer's Patch was collected and weighed. Tissues were snap-frozen in liquid nitrogen and stored frozen at approximately −70° C. or below (total of 105 samples).
Luminal contents were collected for pharmacokinetic analyses from the surface of the tissue from each of five gastrointestinal sections: cecum, proximal colon, transverse colon, distal colon, and rectum (total of 75). The contents were collected in pre-weighed 15-mL conical tubes and the sample weights were recorded. Samples were snap-frozen in liquid nitrogen stored frozen at approximately −70° C. or below.
After removing the luminal content, another set of tissue samples from 3 different areas were collected via an 8.0-mm punch biopsy in each section of the five tissue gastrointestinal sections described above. Around 3 grams of the total punched sample were collected into a pre-weighed 15-mL conical tube, and the tissue weight was recorded (total of 75). Tissues were snap-frozen in liquid nitrogen and stored frozen at approximately −70° C. or below.
A 30-cm length of jejunum (separated into two 15 cm lengths), and the remaining distal and transverse colon tissue sample (after tissue and luminal content were collected for PK) were collected in one animal in each group of treatment, snap-frozen in liquid nitrogen and stored frozen at approximately −70° C. or below. All samples for pharmacokinetic analyses were stored on dry ice before analyses.
Group 2 animals were administered a single oral dose of tacrolimus at 4 mg/0.8 mL (0.08-mg/kg) (in the vehicle solution) on Day 1. Plasma, rectal content sample, tissue collection, GI content collection and related procedures/storage/shipments was the same as those employed in Group 1.
Group 3 animals were administered a single intra-cecal ingestible device containing tacrolimus at 1-mg/0.8 mL (0.02 mg/kg) (in the vehicle solution) on Day 1 by a veterinary surgeon. Plasma, rectal content sample, tissue collection, GI content collection and related procedures/storage/shipments was the same as those employed in Group 1. All samples were analyzed for tacrolimus.
Group 4 animals were administered a single intra-cecal ingestible device of tacrolimus at 2 mg/0.8 mL (0.04 mg/kg) (in sterile vehicle solution) on Day 1 by a veterinary surgeon. Plasma, rectal content sample, tissue collection, GI content collection and related procedures/storage/shipments were the same as those employed in Group 1. All samples were analyzed for tacrolimus.
Group 5 animals are administered a single intra-cecal ingestible device containing tacrolimus at 4 mg/0.8 mL (0.08 mg/kg) (in the vehicle solution) on Day 1 by a veterinary surgeon. Plasma, rectal content sample, tissue collection, GI content collection and related procedures/storage/shipments were the same as those employed in Group 1. All samples were analyzed for tacrolimus.
Detailed clinical observations were conducted daily from Day −10 to −5, and on Day 1. Additional pen-side observations were conducted at least once each day. The animals remained under constant clinical observation for the entire 12 hours from dose until euthanasia. Body weights were collected on Day −10, Day −5, and pre-dose on Day 1. Animals were euthanized via injection of a veterinarian-approved euthanasia.
1. Vehicle solution, 20 mL
Description: 80% alcohol, 20% PEG-60 castor oil
Physical characteristics: clear liquid solution.
2. Prograf (tacrolimus injection), 10 ampules
Description: A sterile solution containing the equivalent of 5 mg anhydrous tacrolimus in 1 mL. Tacrolimus is macrolide immunosuppressant and the active ingredient of Prograf. 0.8 mL of Prograf (5 mg/mL) was administrated through oral gavage per animal in group 2. Prograf (5 mg/mL) was diluted 2× folds (2.5 mg/mL) and 4× folds (1.25 mg/mL) by using vehicle solution. 0.8 mL of each concentration, 1.25 mg/mL, 2.5 mg/mL, and 5 mg/mL of Prograf, was injected into a DSS ingestible device for group 3, 4, and 5.
Formulation: Each mL contained polyoxyl 60 hydrogenated castor oil (HCO-60), 200 mg, and dehydrated alcohol, USP, 80.0% v/v.
Physical characteristics: clear liquid solution.
3. DDS ingestible device containing Tacrolimus
Description: Three (3) DDS ingestible devices containing vehicle solution for Group 1, three (3) DSS ingestible devices containing 1 mg tacrolimus for Group 3, three (3) DDS ingestible devices containing 2 mg tacrolimus for Group 4, and three (3) DDS ingestible devices containing 4 mg tacrolimus for Group 5.
Animals were acclimated prior to study initiation for at least 7 days. Animals in obvious poor health were not placed on study.
Other than veterinary-approved anesthetics and medications used during surgery to install the ileocecal ports, or for vehicle or test article administration, and analgesia and antibiotics post-surgery, no further medications were employed.
All swine were fasted at least 24 hours before being anesthetized and properly medicated for surgery or overnight before dosing. Otherwise, animals were fed ad-libitum. Tap water was pressure-reduced and passed through a particulate filter, then a carbon filter prior to supply to an automatic watering system. Water was supplied ad libitum. There were no known contaminants in the feed or water that would be expected to interfere with this study.
The data in
Significantly higher Cmax values (9.20±3.30 and 21.80±4.73 ng/mL) were observed in groups treated with high (0.09 mg/kg) and moderate (0.04 mg/kg) dose of tacrolimus when delivered through IC capsule as compared to the Cmax values following PO delivery of tacrolimus (0.09 mg/kg). Significantly higher tissue (spiral and transverse colon) and luminal content (spiral, transverse, and distal colon) concentrations were observed in groups treated with high and moderate dose tacrolimus delivered through IC capsule as compared to the levels observed in animals administered tacrolimus via PO. No measurable level of tacrolimus was detected in tissue when animals were delivered tacrolimus via PO, despite systemic concentrations equivalent to low dose IC group (0.02 mg/kg) (
These data suggest that intra-cecal administration of tacrolimus is able to locally deliver tacrolimus to the tissues in the GI tract of a mammal, while not decreasing the systemic immune system of a mammal.
The purpose of this non-Good Laboratory Practice (GLP) study was to explore the PK/PD and bioavailability of adalimumab when applied to (Dextran Sulfate Sodium Salt) DSS-induced colitis in Yorkshire-cross farm swine, and to evaluate topical Humira® (adalimumab or ADA) in DSS-colitis in swine. Colitis was induced in weanling YorkShire-Cross farm swine by administering DSS once daily for 7 consecutive days via oral gastric intubation. The dose levels were chosen based on the doses and regimens used to induce colitis in weanling pigs. The doses of DSS were 1.275 or 2.225 g/k/day for Groups 2 and 3, respectively.
This study used one group of 19- to 21-day old weanling swine, and 2 groups of three, 19- to 20-day old weanling swine that weighed from 6.5 to 7.5 kg on arrival. To induce colitis, on study day 1 through and including day 7, animals in Groups 2 and 3 were administered once daily oral (gastric intubation) doses of DSS at 8.5% or 15% w/v for dose levels of 1.275 or 2.25 g/kg/day, respectively (Groups 2 and 3, respectively, 2 hours before morning feeding). The Group 1 control animal was administered sterile saline only. Each animal was placed in a sling for dosing. Animals were fasted at least 6 hours prior to each dose. See Table 30.
1Animal weighed around 6.5-7.5 kg.
2Daily clinical signs and body weight were closely monitored throughout the study. If severe clinical signs or body weight loss is observed at day 1~3 after dosing, the DSS dosing was shortened to 5 days.
30.8 mL of ADA solution was dosed rectally to the colon via an endoscope.
4Necropsy was done to observe GI inflammation and overall histopathology.
The day following the last DSS dose, using endoscopy and a catheter, at 13 mg adalimumab/0.8 mL/pig (one 40 mg adalimumab/0.8 mL dosage syringe was divided into 3 parts and diluted with PBS) was placed in the proximal portion of the descending colon just past the bend of the transverse colon. Alternatively, 13 mg of adalimumab was diluted with PBS to a volume suitable for dosing post-weanling swine. Prior to dosing, endoscopy photographs were taken of the mucosal surface of the colon. Animals were anesthetized during adalimumab dosing. Prior to adalimumab dosing, animals were housed on rubber mats to prevent ingestion of bedding material, and were fasted at least 24 hours. The colon was cleansed using an enema prior to the procedure.
All animals were properly euthanized approximately 3 hours post-adalimumab-dose for tissue collections and subjected to a gross necropsy with emphasis on the severity of colitis (immediately after euthanasia, in order to avoid autolytic changes). All samples for histology were fixed in a fixation medium and the punch-biopsy sample snap-frozen in liquid nitrogen and stored frozen (−70° C.).
To measure drug content, tissue samples and luminal content were collected by gently removing and collecting luminal content first, then using an 8.0 mm-punch biopsy tool. Biopsies from three different areas at the site of adalimumab administration were collected in each animal. Additional tissue biopsy samples were collected from three different areas at the proximal colon, and the proximal region of transverse colon in each animal. Approximately 3 g of total punched sample and 200 mg of luminal content were collected in a pre-weighed conical tubes and the tissue weighed was recorded.
Approximately, a 5-cm length of open gastrointestinal tissue sample including terminal ileum, cecum (CAC); proximal colon (PCN); transverse colon (TCN); spiral colon, distal colon (DCN), and rectum was collected, gently rinsed in saline to remove luminal material, and individually fixed in fixation buffer (10% neutral buffered formalin). Also, a 5-cm length of open gastrointestinal tissue from 3 different areas near the site of adalimumab administration was collected and fixed in formalin in the same manner for immunohistochemical staining for adalimumab. Tissue samples for histopathology were fixed in 10% neutral buffered formalin for 18˜24 hr, and transferred to 70% ethanol.
HUMIRA® was supplied in single-use, 1-mL pre-filled glass syringes, as a sterile, preservative-free solution for subcutaneous administration. The solution of HUMIRA® was clear and colorless, with a pH of about 5.2. Each syringe delivered 0.8 mL (40 mg adalimumab) of drug product. Each vial contained approximately 0.9 mL of solution to deliver 0.8 mL (40 mg adalimumab) of drug product. Each 0.8 mL HUMIRA® contained 40 mg adalimumab, 4.93 mg sodium chloride, 0.69 mg monobasic sodium phosphate dihydrate, 1.22 mg dibasic sodium phosphate dihydrate, 0.24 mg sodium citrate, 1.04 mg citric acid monohydrate, 9.6 mg mannitol, 0.8 mg polysorbate 80, and water for injection. Sodium hydroxide was added as necessary to adjust pH.
All animals were randomized into groups of three. Animals were dosed once with adalimumab via subcutaneous (SC), perirectal (PR), or intracecal (IC) administration.
The concentration of adalimumab and TNFα was measured in plasma at 1, 2, 3, 4, 6, and 12 hours post-dose. The concentration of adalimumab was measured in rectal contents at 1, 3, 6, and 12 hours post-dose and in luminal content at 12 hours post-dose. Concentration of adalimumab and TNFα, HER2, and total protein was measured in gastrointestinal tissue, e.g., cecum sample (CAC), proximal colon sample (PCN), transverse colon sample (TCN), distal colon sample (DCNi) inflamed, distal colon non-inflamed sample (DCNn), and rectum sample (RTM), at 12 hours post-dose.
Treatment with 8.5% DSS (oral; Day 1 to Day 7) induced mild body weight loss, hemorrhage diarrhea, soft bloody stool, and moderate colitis in swine. Necropsy revealed marked edema and full thickness of mucosal erosion from the proximal colon through the distal rectum. The 8.5% DSS-induced animals were treated with adalimumab at day 8. No significant differences in clinical observations, GI-specific adverse effects or toxicity due to adalimumab treatment were observed. The 15% DSS (oral; Day 1 to Day 7)-induced animals had marked mucosal sloughing and hemorrhage from cecum to rectum and severe colitis. All of the animals were euthanized early on day 5.
Significant lesions of colitis were found in animals treated with 8.5% DSS and were characterized by inflammation that involved mucosa and submucosa, loss of surface epithelium (erosion), and intestinal crypts (
There was little, if any, evidence of regeneration. The ileum and cecum were unremarkable in all animals except cecum from one animal (animal 2504) that was treated with 8.5% DSS, which had lesions of inflammation and loss of surface and crypt epithelium (
As a proof of concept, the patient population of this study is patients that (1) have moderate to severe ulcerative colitis, regardless of extent, and (2) have had an insufficient response to a previous treatment, e.g., a conventional therapy (e.g., 5-ASA, corticosteroid, and/or immunosuppressant) or a FDA-approved treatment. In this placebo-controlled eight-week study, patients are randomized. All patient undergo a colonoscopy at the start of the study (baseline) and at week 8. Patients enrolled in the study are assessed for clinical status of disease by stool frequency, rectal bleeding, abdominal pain, physician's global assessment, and biomarker levels such as fecal calprotectin and hsCRP. The primary endpoint is a shift in endoscopy scores from Baseline to Week 8. Secondary and exploratory endpoints include safety and tolerability, change in rectal bleeding score, change in abdominal pain score, change in stool frequency, change in partial Mayo score, change in Mayo score, proportion of subjects achieving endoscopy remission, proportion of subjects achieving clinical remission, change in histology score, change in biomarkers of disease such as fecal calprotectin and hsCRP, level of adalimumab in the blood/tissue/stool, change in cytokine levels (e.g., TNFα, IL-6) in the blood and tissue.
For example, treatment for a patient that is diagnosed with ulcerative colitis is an ingestible device programmed to release a single bolus of a therapeutic agent, e.g., 40 mg adalimumab, in the cecum or proximal to the cecum. Prior to administration of the treatment, the patient is fasted overnight and is allowed to drink clear fluids. Four hours after swallowing the ingestible device, the patient can resume a normal diet. An ingestible device is swallowed at the same time each day. The ingestible device is not recovered.
In some embodiments, there may be two different ingestible devices: one including an induction dose (first 8 to 12 weeks) and a different ingestible device including a different dose or a different dosing interval.
In some examples, the ingestible device can include a mapping tool, which can be used after 8 to 12 weeks of induction therapy, to assess the response status (e.g., based on one or more of the following: drug level, drug antibody level, biomarker level, and mucosal healing status). Depending on the response status determined by the mapping tool, a subject may continue to receive an induction regimen or maintenance regimen of adalimumab.
In different clinical studies, the patients may be diagnosed with Crohn's disease and the ingestible devices (including adalimumab) can be programmed to release adalimumab in the cecum, or in both the cecum and transverse colon.
In different clinical studies, the patients may be diagnosed with ileocolonic Crohn's disease and the ingestible devices (including adalimumab) can be programmed to release adalimumab in the late jejunum or in the jejunum and transverse colon.
The primary objective of this study was to study the pharmacokinetics of oral versus intra-cecal administration of tacrolimus in normal Yorkshire-Cross farm swine.
This study compares the effects of administration of: a single intra-cecal administration of a device containing 0.8 mL sterile vehicle solution (80% alcohol, 20% castor oil (HCO-60)); a single oral dose of tacrolimus at 0.09 mg/kg (in sterile vehicle solution); and a single intra-cecal administration of a device containing either 0.02 mg/kg (in sterile vehicle solution), 0.04 mg/kg (in sterile vehicle solution), or 0.09 mg/kg (in sterile vehicle solution).
This study employed five groups of three female swine weighing approximately 45 to 50 kg at study start. Swine were randomly placed into animal rooms/pens as they are transferred from the delivery vehicle without regard to group. Group numbers were assigned to the rooms in order of room number. No further randomization procedure was employed. The study design is provided in Table 32.
Animals in Group 1 received intra-cecally a device containing a vehicle solution (80% alcohol, 20% HCO-60). Animals in Group 2 received orally a liquid formulation of tacrolimus at 0.09 mg/kg per animal. Animals in Group 3 received intra-cecally a device containing tacrolimus at 0.02 mg/kg per device. Animals in Group 4 received intra-cecally a device containing tacrolimus 0.04 mg/kg per device. Animals in Group 5 received intra-cecally a device containing tacrolimus 0.09 mg/kg per device.
Samples of rectal contents were collected for pharmacokinetic analyses from each animal at each of 1, 3, 6, and 12 hours post-device placement using a fecal swab (rectal swab).
The concentration of tacrolimus measured was measured in the blood at 1-, 2-, 3-, 4-, 6-, and 12-hours post-dose. The concentration of tacrolimus was measured in rectal contents at 1-, 3-, 6-, and 12-hours post-dose, and in the gastrointestinal tissue and luminal content, e.g., the cecum tissue and lumen, the proximal colon tissue and lumen, the spiral colon tissue and lumen, the transverse colon tissue and lumen, and the distal colon tissue and lumen, at 12 hours post-dose.
The data in
These data suggest that intra-cecal administration of tacrolimus is able to locally deliver tacrolimus to the tissues in the GI tract of a mammal.
A summary of the results are shown in Table 33.
Tables 34 and 35 provide the tissue and plasma ratios of the animals in Groups 2-5.
An ingestible medical device according to the disclosure (“TLC1”) was tested on 20 subjects to investigate its localization ability. TLC1 was a biocompatible polycarbonate ingestible device that contained a power supply, electronics and software. An onboard software algorithm used time, temperature and reflected light spectral data to determine the location of the ingestible device as it traveled the GI tract. The ingestible device is 0.51×1.22 inches which is larger than a vitamin pill which is 0.4×0.85 inches. The subjects fasted overnight before participating in the study. Computerized tomography (“CT”) were used as a basis for determining the accuracy of the localization data collected with TLC1. One of the 20 subjects did not follow the fasting rule. CT data was lacking for another one of the 20 subjects. Thus, these two subjects were excluded from further analysis. TLC1 sampled RGB data (radially transmitted) every 15 seconds for the first 14 hours after it entered the subject's stomach, and then samples every five minutes after that until battery dies. TLC1 did not start to record optical data until it reached the subject's stomach. Thus, there was no RGB-based data for the mouth-esophagus transition for any of the subjects.
In addition, a PillCam® SB (Given Imaging) device was tested on 57 subjects. The subjects fasted overnight before joining the study. PillCam videos were recorded within each subject. The sampling frequency of PillCam is velocity dependent. The faster PillCam travels, the faster it would sample data. Each video is about seven to eight hours long, starting from when the ingestible device was administrated into the subject's mouth. RGB optical data were recorded in a table. A physician provided notes on where stomach-duodenum transition and ileum-cecum transition occurred in each video. Computerized tomography (“CT”) was used as a basis for determining the accuracy of the localization data collected with PillCam.
For TLC1, it was assumed that this transition occurred one minute after the patient ingested the device. For PillCam, the algorithm was as follows:
For one of the PillCam subjects, there was not a clear cut difference between the esophagus and stomach, so this subject was excluded from future analysis of stomach localization. Among the 56 valid subjects, 54 of them have correct esophagus-stomach transition localization. The total agreement is 54/56=96%. Each of the two failed cases had prolonged esophageal of greater than one minute. Thus, adding one minute to mouth-esophagus transition was not enough to cover the transition in esophagus for these two subjects.
For both TLC1 and PillCam, a sliding window analysis was used. The algorithm used a dumbbell shape two-sliding-window approach with a two-minute gap between the front (first) and back (second) windows. The two-minute gap was designed, at least in part, to skip the rapid transition from stomach to small intestine and capture the small intestine signal after ingestible device settles down in small intestine. The algorithm was as follows:
For TLC1, one of the 18 subjects had too few samples (<3 minutes) taken in the stomach due to the delayed esophagus-stomach transition identification by previously developed localization algorithm. Thus, this subject was excluded from the stomach-duodenum transition algorithm test. For the rest of the TLC1 subjects, CT images confirmed that the detected pyloric transitions for all the subjects were located somewhere between stomach and jejunum. Two out of the 17 subjects showed that the ingestible device went back to stomach after first the first stomach-duodenum transition. The total agreement between the TLC1 algorithm detection and CT scans was 17/17=100%.
For one of the PillCam subjects, the ingestible device stayed in the subject's stomach all the time before the video ended. For another two of the PillCam subjects, too few samples were taken in the stomach to run the localization algorithm. These three PillCam subjects were excluded from the stomach-duodenum transition localization algorithm performance test. The performance summary of pyloric transition localization algorithm for PillCam was as follows:
The total agreement for the PillCam stomach-duodenum transition localization algorithm detection and physician's notes was 48/54=89%.
For TLC1, it was assumed that the device left the duodenum and entered the jejunum three minutes after it was determined that the device entered the duodenum. Of the 17 subjects noted above with respect to the TLC1 investigation of the stomach-duodenum transition, 16 of the subjects mentioned had CT images that confirmed that the duodenum jejunum transition was located somewhere between stomach and jejunum. One of the 17 subjects had a prolonged transit time in duodenum. The total agreement between algorithm detection and CT scans was 16/17=94%.
For PillCam, the duodenum-jejunum transition was not determined.
It is to be noted that the jejunum is redder and more vascular than ileum, and that the jejunum has a thicker intestine wall with more mesentery fat. These differences can cause various optical responses between jejunum and ileum, particularly for the reflected red light signal. For both TLC1 and PillCam, two different approaches were explored to track the change of red signal at the jejunum-ileum transition. The first approach was a single-sliding-window analysis, where the window is 10 minutes long, and the mean signal was compared with a threshold value while the window was moving along. The second approach was a two-sliding-window analysis, where each window was 10 minutes long with a 20 minute spacing between the two windows. The algorithm for the jejunum-ileum transition localization was as follows:
For TLC1, 16 of the 18 subjects had CT images that confirmed that the detected jejunum-ileum transition fell between jejunum and cecum. The total agreement between algorithm and CT scans was 16/18=89%. This was true for both the single-sliding-window and double-sliding-window approaches, and the same two subjects failed in both approaches.
The performance summary of the jejunum-ileum transition detection for PillCam is listed below:
Data demonstrated that, for TLC1, mean signal of reflected red/green provided the most statistical difference before and after the ileum-cecum transition. Data also demonstrated that, for TLC1, the coefficient of variation of reflected green/blue provided the most statistical contrast at ileum-cecum transition. The analysis based on PillCam videos showed very similar statistical trends to those results obtained with TLC1 device. Thus, the algorithm utilized changes in mean value of reflected red/green and the coefficient of variation of reflected green/blue. The algorithm was as follows:
The flag setting and location reversal criteria particularly designed for TLC1 device were as follows:
For TLC1, 16 of the 18 subjects had CT images that confirmed that the detected ileum-cecum transition fell between terminal ileum and colon. The total agreement between algorithm and CT scans was 16/18=89%. Regarding those two subject where the ileum-cecum transition localization algorithm failed, for one subject the ileum-cecum transition was detected while TLC1 was still in the subject's terminal ileum, and for the other subject the ileum-cecum transition was detected when the device was in the colon.
Among the 57 available PillCam endoscopy videos, for three subjects the endoscopy video ended before PillCam reached cecum, and another two subjects had only very limited video data (less than five minutes) in the large intestine. These five subjects were excluded from ileum-cecum transition localization algorithm performance test. The performance summary of ileum-cecum transition detection for PillCam is listed below:
red/green at ileum-cecum transition The total agreement between ileocecal transition localization algorithm detection and the physician's notes is 39/52=75% if considering good cases only. Total agreement including possibly acceptable cases is 48/52=92.3%.
Data demonstrated that, for TLC1, mean signal of reflected red/green provided the most statistical difference before and after the cecum-colon transition. Data also demonstrated that, for TLC1, the coefficient of variation of reflected blue provided the most statistical contrast at cecum-colon transition. The same signals were used for PillCam. The cecum-colon transition localization algorithm was as follows:
The threshold values above were chosen based on a statistical analysis of data taken by TLC1.
For TLC1, 15 of the 18 subjects had the cecum-colon transition detected somewhere between cecum and colon. One of the subjects had the cecum-colon transition detected while TLC1 was still in cecum. The other two subjects had both wrong ileum-cecum transition detection and wrong cecum-colon transition detection. The total agreement between algorithm and CT scans was 15/18=83%.
For PillCam, for three subjects the endoscopy video ended before PillCam reached cecum, and for another two subjects there was very limited video data (less than five minutes) in the large intestine. These five subjects were excluded from cecum-colon transition localization algorithm performance test. The performance summary of cecum-colon transition detection for PillCam is listed below:
The total agreement: 27/52=52%.
Table 36 summarizes the localization accuracy results.
In the following cases, each subject is treated by administering an ingestible device as disclosed herein, said device containing a drug, or a pharmaceutical formulation containing the drug. The device has a self-localization mechanism that autonomously determines the device location within the subject's GI tract. The device localization mechanism includes one or more sensors associated with the device that detects light reflectance that is external to the device and present in the GI tract. Based on pre-determined identification of disease site(s) in a particular section or subsection of the GI tract, as disclosed in each case, the device is pre-programmed with instructions to release the drug, or the pharmaceutical formulation containing the drug, to or proximal to the section of the GI tract containing the disease site(s). The instructions are provided from at least one processor and/or at least one controller associated with the at least one sensor. The device contains a therapeutically effective amount of the drug (preferably, a monoclonal antibody selected from the group consisting of ustekinumab or a biosimilar thereof; brazikumab or a biosimilar thereof; guselkumab or a biosimilar thereof; mirikizumab or a biosimilar thereof; and risankizumab or a biosimilar thereof, each optionally formulated as a solid, or as a solution having a concentration of at least about 110 mg/mL, at least about 125 mg/mL, or at least about 150 mg/mL; or the drug is optionally Compound A, Compound B or Compound C, as disclosed in U.S. Pat.

In the following 2 cases, based on pre-determined identification of disease site(s) in the jejunum, as disclosed in each case, the device is pre-programmed with instructions to release the drug to the jejunum to treat the disease site(s).
(i) A 68-year old female subject suffering from symptoms of gastrointestinal pain and discomfort goes to see her doctor. The subject subsequently undergoes a video endoscopy, which reveals disease site(s) in the tissue in the jejunum. Subsequently, the subject is orally administered the ingestible device containing the therapeutically effective amount of the drug. After ingestion of the device, data collected from at least one of the light sensors, together with elapsed time through the GI tract after the oral administration, indicates that the device has transitioned into the jejunum with at least about 90% accuracy. In this particular case, the light reflectance detected by the sensors includes green light and blue light; an increase in the ratio of the green to blue reflectance is used to determine that the device has transitioned from the stomach to the duodenum; a period of elapsed time (about 3 minutes) after the transition to the duodenum is then used to determine that the device has transitioned from the duodenum to the jejunum. Optionally, peristaltic contraction frequency data are used to corroborate that the device has entered the jejunum. The drug, or the pharmaceutical formulation containing the drug, is then released from the device based on the instructions, providing topical delivery of the drug, or the pharmaceutical formulation containing the drug, to the jejunum containing one or more disease sites. The subject subsequently undergoes an endoscopy to determine the effect of the treatment.
(ii) Treatment of Crohn's disease in the jejunum by releasing drug in the jejunum. A subject having unexplained weight loss and fever goes to urgent care. The subject later undergoes an endoscopy, which reveals that the subject has disease site(s) in the tissue in the jejunum associated with Crohn's disease. Subsequently, the subject is orally administered the ingestible device containing the therapeutically effective amount of the drug. After ingestion of the device, data collected from at least one of the light sensors, together with elapsed time through the GI tract after the oral administration, indicates that the device has transitioned into the jejunum with at least about 90% accuracy. In this particular case, the light reflectance detected by the sensors includes green light and blue light; an increase in the ratio of the green to blue reflectance is used to determine that the device has transitioned from the stomach to the duodenum; a period of elapsed time (about 3 minutes) after the transition to the duodenum is then used to determine that the device has transitioned from the duodenum to the jejunum. Optionally, peristaltic contraction frequency data are used to corroborate that the device has entered the jejunum. The drug, or the pharmaceutical formulation containing the drug, is then released from the device based on the instructions, providing topical delivery of the drug, or the pharmaceutical formulation containing the drug, to the jejunum containing one or more disease sites. The subject subsequently undergoes an endoscopy to determine the effect of the treatment.
In the following 3 cases, based on pre-determined identification of disease site(s) in the ileum, as disclosed in each case, the device is pre-programmed with instructions to release the drug to the ileum to treat the disease site(s).
(i) A 42-year old female subject suffering from gastrointestinal cramping and fatigue makes an appointment with a gastroenterologist. The subject undergoes an endoscopy, which reveals that she has disease site(s) in the tissue in the ileum. Subsequently, the subject is orally administered the ingestible device containing the therapeutically effective amount of the drug.
After ingestion of the device, data collected from at least one of the light sensors, together with elapsed time through the GI tract after the oral administration, indicates that the device has transitioned from the jejunum to the ileum with at least about 80% accuracy. In this particular case, the light reflectance detected by the sensors includes red light. Once the device has reached the jejunum (essentially as determined in Example 15-1b(i)), a detected decrease in red light reflectance is used to determine that the device has transitioned from the jejunum to the ileum. The drug, or the pharmaceutical formulation containing the drug, is then released from the device based on the instructions, providing topical delivery of the drug, or the pharmaceutical formulation containing the drug, to the ileum containing one or more disease sites. The subject subsequently undergoes an endoscopy to determine the effect of the treatment.
(ii) Treatment of ulcerative colitis with backwash ileitis by releasing drug in the ileum. A 42-year old female subject with a history of pancolitis visits her treating physician. The subject undergoes an endoscopy, which reveals that the subject has patchy cryptitis and crypt abscesses in the distal ileum thought to be due to backwash of cecal contents (“backwash ileitis”). Subsequently, the subject is orally administered the ingestible device containing the therapeutically effective amount of the drug. After ingestion of the device, data collected from at least one of the light sensors, together with elapsed time through the GI tract after the oral administration, indicates that the device has transitioned from the jejunum to the ileum with at least about 80% accuracy. In this particular case, the light reflectance detected by the sensors includes red light. Once the device has reached the jejunum (essentially as determined in Example 15-1b(i)), a detected decrease in red light reflectance is used to determine that the device has transitioned from the jejunum to the ileum. The drug, or the pharmaceutical formulation containing the drug, is then released from the device based on the instructions, providing topical delivery of the drug, or the pharmaceutical formulation containing the drug, to the ileum containing one or more disease sites. The subject subsequently undergoes an endoscopy to determine the effect of the treatment.
(iii) Treatment of Crohn's disease in the ileum by releasing drug in the ileum. A subject suffering from symptoms of Crohn's disease, including abdominal pain and cramping, walks into a clinic.

After ingestion of the device, data collected from at least one of the light sensors, together with elapsed time through the GI tract after the oral administration, indicates that the device has transitioned from the jejunum to the ileum with at least about 80% accuracy. In this particular case, the light reflectance detected by the sensors includes red light. Once the device has reached the jejunum (essentially as determined in Example 15-1b(i)), a detected decrease in red light reflectance is used to determine that the device has transitioned from the jejunum to the ileum. The drug, or the pharmaceutical formulation containing the drug, is then released from the device based on the instructions, providing topical delivery of the drug, or the pharmaceutical formulation containing the drug, to the ileum containing one or more disease sites. The subject subsequently undergoes an endoscopy to determine the effect of the treatment.
In the following 3 cases, based on pre-determined identification of disease site(s) in the cecum, as disclosed in each case, the device is pre-programmed with instructions to release the drug to the cecum to treat the disease site(s).
(i) A 25-year old male subject suffering from symptoms of gastrointestinal inflammation walks into a clinic.

Subsequently, the subject is orally administered the ingestible device containing the therapeutically effective amount of the drug. After ingestion of the device, data collected from at least one of the light sensors, optionally in conjunction with elapsed time through the GI tract after the oral administration, indicates that the device has transitioned into the cecum with at least about 80% accuracy. In this particular case, the light reflectance detected by the sensors includes red, green and blue light. A decrease in the ratio of the red to green reflectance, together with a decrease in the ratio of the green to blue reflectance, are used to determine that the device has transitioned from the ileum to the cecum. The drug, or the pharmaceutical formulation containing the drug, is then released from the device based on the instructions, providing topical delivery of the drug, or the pharmaceutical formulation containing the drug, to the cecum containing one or more disease sites. The subject subsequently undergoes an endoscopy to determine the effect of the treatment.
(ii) Treatment of ulcerative colitis in the cecum by releasing drug in the cecum. A subject with a history of ulcerative colitis returns to the clinic.

A set of experiments was performed to compare the efficacy of targeted intracecal (IC) anti-mouse-TNFα antibody (a surrogate for adalimumab) and anti-mouse-interleukin (IL) 12p40 antibody (a surrogate of anti-human-IL12p40 antibody) with systemic intraperitoneal (IP) injection in an adoptive T cell transfer induced chronic colitis mouse model.
The details of the study design are summarized in Table 37. A detailed description of the methods used in this study is provided below.
A cohort of animals underwent surgical implantation of a cecal cannula at least 10 days to 2 weeks prior to the experiment for the ease of bolus topical delivery to the cecum. A sufficient number of animals underwent implantation to allow for enough cannulated animals to be enrolled in the main study. An additional n=8 animals (Group 9) served as no surgery/no disease controls.
Colitis was induced by intraperitoneal (IP) injection of 0.5×106 CD44/CD62L+ T-cells from C57BL/6 donor mice to male RAG2−/− recipient mice in Groups 2 to 8 on Day 0. The donor cells were processed by first harvesting spleens from 80 C57Bl/6 mice and then isolating the CD44−/CD62L+ T cells using Miltenyi Magnetic-Activated Cell Sorting (MACS) columns.
To minimize variation due to methods of administration, animals were treated both by IP injection every third day (3×/wk) and IC injection once daily for 42 consecutive days (qd×42d) of either the test article or the control (vehicle solution or IgG control). Groups were as outlined in Table 37, also summarized as follows: Group 1=untreated (no disease controls); Group 2=vehicle [phosphate buffer saline (PBS)] (IP)+vehicle (IC); Group 3=IgG (IP)+vehicle (IC); Group 4=vehicle (IP)+IgG (IC); Group 5=anti-IL12p40 (IP)+vehicle (IC); Group 6=vehicle (IC)+anti-IL12p40 (IC); Group 7=anti-TNFα (IP)+vehicle (IC); Group 8=vehicle (IP)+anti-TNFα (IC); Group 9=no surgery, untreated (no-cannulation and no-disease controls (sentinel animals for bedding)). Treatment with test article was initiated on Day 0 and was continued until Day 42 as outlined in Table 37.
All recipient mice were weighed daily and assessed visually for the presence of diarrhea and/or bloody stool. The cages were changed every two weeks starting on Day 7, with care taken to capture ¼ of dirty cage material for transfer to the new cage. On Day 13, blood was collected via RO eye bleed, centrifuged, and plasma was aliquoted (50 μL and remaining) and frozen for downstream analysis. The pelleted cells were re-suspended in buffer to determine the presence of T cells by FACS analysis of CD45+/CD4+ events.
On Day 13, after dosing, peripheral blood from all surviving mice was analyzed by flow cytometry from the presence of CD45+/CD4+ T cells.
The mice underwent high definition video endoscopy on Days 14 (pre-dosing; baseline), 28, and 42 (before euthanasia) to assess the extent of colitis severity. Images were captured from each animal at the most severe region of disease identified during endoscopy. Stool consistency was scored during endoscopy using the parameters described herein on Days 14, 18 and 42.
Disease Activity Index (DAI) was calculated using a combination of body weight (BW) loss score, colitis score, stool consistency score. The DAI (combined value from 0 to 13) was calculated using colitis score, stool consistency score, and BW loss score to provide an overall evaluation of the disease intensity (see Table 38). The score from animals with unscheduled death was carried forward to limit any bias that may be introduced by mortality.
The animals from all groups were euthanized by CO2 inhalation on Day 42 following endoscopy and three hours after dosing. Terminal blood samples were collected for bioanalysis of inflammatory cytokines, and tissues samples were collected and fixed for histopathological evaluation. Plasma obtained from these samples was split into two separate cryotubes, with 50 μL in one tube (Bioanalysis) and the remainder in a second tube (TBD). The cecum and colon contents were removed and the contents collected, weighed, and snap frozen in separate cryovials. The mesenteric lymph nodes were collected and flash-frozen in liquid nitrogen. The small intestine were excised and rinsed, and the most distal 2-cm of ileum was placed in formalin for 24 hours and then transferred to 70% ethanol for subsequent histological evaluation. The Peyer's patches were collected from the small intestine, and were flash-frozen in liquid nitrogen. The colon was rinsed, measured, weighed, and then trimmed to 6-cm in length and divided into 5 pieces as described in the above Examples. The most proximal 1-cm of colon was separately weighed, and flash-frozen for subsequent bioanalysis (PK) of test article levels. Of the remaining 5-cm of colon, the most distal and proximal 1.5-cm sections were each placed in formalin for 24 hours and then transferred to 70% ethanol for subsequent histological evaluation. The middle 2-cm portion was bisected longitudinally, and each piece was weighed, placed into two separate cryotubes, and snap frozen in liquid nitrogen; one of the samples was used for cytokine analysis and the other was used for myeloperoxidase (MPO) analysis. All plasma and frozen colon tissue samples were stored at −80° C. until used for endpoint analysis.
The colon weight (mg) to length (cm) ratio was calculated for individual mice.
A more detailed description of the protocols used in this study are described below.
Animals were placed under isoflurane anesthesia, and the cecum was exposed via a mid-line incision in the abdomen. A small point incision was made in the distal cecum through which 1-2 cm of the cannula was inserted. The incision was closed with a purse-string suture using 5-0 silk. An incision was made in the left abdominal wall through which the distal end of the cannula was inserted and pushed subcutaneously to the dorsal aspect of the back. The site was washed copiously with warmed saline prior to closing the abdominal wall. A small incision was made in the skin of the back between the shoulder blades, exposing the tip of the cannula. The cannula was secured in place using suture, wound clips, and tissue glue. All of the animals received 1 mL of warm sterile saline (subcutaneous injection) and were monitored closely until fully recovered before returning to the cage. All animals received buprenorphine at 0.6 mg/kg BID for the first 3 days, and Baytril at 10 mg/kg QD for the first 5 days following surgery.
Colitis was induced on Day 0 in male RAG2−/− mice by IP injection (200 μL) of 0.5×106 CD44−/CD62L+ T cells (in PBS) isolated and purified from C57Bl/6 recipients.
Whole spleens were excised from C57Bl/6 mice and immediately placed in ice-cold PBS. The spleens were dissociated to yield a single cell suspension and the red blood cells were lysed. The spleens were then processed for CD4+ enrichment prior to CD44−CD62L+ sorting by MACS.
See Table 37.
The animals were observed daily (morbidity, survival, presence of diarrhea and/or bloody stool) in order to assess possible differences among treatment groups and/or possible toxicity resulting from the treatments. Animals were weighed daily and their percent body weight relative to Day 0 was calculated.
The animals were monitored on a daily basis and those exhibiting weight loss greater than 30% were euthanized, and did not have samples collected.
Each mouse underwent video endoscopy on Days 14 (pre-dosing; baseline), 28, and 42 (before euthanasia) using a small animal endoscope (Karl Storz Endoskope, Germany), under isoflurane anesthesia. During each endoscopic procedure, still images as well as video were recorded to evaluate the extent of colitis and the response to treatment. Additionally, an image from each animal at the most severe region of disease identified during endoscopy was captured. Colitis severity was scored using a 0-4 scale (0=normal; 1=loss of vascularity; 2=loss of vascularity and friability; 3=friability and erosions; 4=ulcerations and bleeding). Additionally, stool consistency was scored during endoscopy using the scoring system described herein.
Terminal blood (plasma and cell pellet), Peyer's patches (Groups 1-8 only), small intestine and colon mLN (Groups 1-8 only), cecum contents, colon contents, small intestine, and colon were collected at euthanasia, as follows.
Blood: Terminal blood was collected by cardiac puncture and plasma generated from these samples. The resulting plasma was split into two separate cryotubes with 50 μL in one tube (Bioanalysis), and the remainder in a second tube (TBD).
Mesenteric Lymph Nodes: The mesenteric lymph nodes were collected, weighed, snap-frozen in liquid nitrogen, and stored at −80° C.
Small Intestine: The small intestine was excised and rinsed, and the most distal 2-cm of ileum will be placed in formalin for 24 hours and then transferred to 70% ethanol for subsequent histological evaluation.
Peyer's Patches: The Peyer's patches were collected from the small intestine. The collected Peyer's patches were weighed, snap-frozen in liquid nitrogen, and stored at −80° C.
Cecum/Colon Contents: The cecum and colon were removed from each animal and contents collected, weighed, and snap-frozen in separate cryovials.
Colon: Each colon was rinsed, measured, weighed, and then trimmed to 6-cm in length and divided into 5 pieces as outlined herein. The most proximal 1-cm of colon was separately weighed, and snap frozen for subsequent bioanalysis (PK) of test article levels. Of the remaining 5-cm of colon, the most distal and proximal 1.5-cm sections were placed in formalin for 24 hours and then transferred to 70% ethanol for subsequent histological evaluation. The middle 2-cm portion was bisected longitudinally, and each piece weighed, placed into two separate cryotubes, and snap-frozen in liquid nitrogen; one of these samples was used for cytokine analysis and the other sample was used for myeloperoxidase analysis.
Cytokine levels (IFNγ, IL-2, IL-4, IL-5, IL-1β, IL-6, IL-12 p40, and TNFα) were assessed in colon tissue homogenate (all groups) by multiplex analysis. Myeloperoxidase levels were assessed by ELISA in colon tissue homogenate (all groups).
Ileum, proximal colon, and distal colon samples from seventy-one mice were fixed in 10% neutral buffered formalin. Samples were trimmed into three cross sections per portion and processed routinely into two blocks per animal (ileum in one block, proximal and distal colon in a second block). One slide from each block was sectioned at approximately 5 microns and stained with hematoxylin and eosin (H&E). Glass slides were evaluated with light microscopy by a board-certified veterinary pathologist. Ileum, proximal colon, and distal colon samples were scored individually. Lesions in H&E-stained samples were given a severity score 0-51 (0=not present/normal, 1=minimal, <10% of tissue affected; 2=mild, 10-25% of tissue affected; 3=moderate, 26-50% of tissue affected; 4=marked, 51-79% of tissue affected; 5=severe, >75% of the tissue affected). Inflammation, crypt damage, erosion, and hyperplasia scores were added together to determine a sum colitis score for each sample.
Lymphocyte counts were performed in a subset of samples: proximal and distal colon from Groups 2 (vehicle), 7 (anti-TNF alpha IP; vehicle IC), and 8 (anti-TNF alpha IC; vehicle IP). In each piece of tissue, a randomly identified site was divided into approximately four segments extending from the lumen to the muscularis mucosae; 100 μm2 fields were used in the proximal colon, and 50 μm2 fields were used in the distal colon due to the differences in mucosal thickness. Using H&E-stained slides, the number of cells with lymphocyte morphology (small round nucleus with condensed chromatin) were counted within the overlying surface epithelium, in each field from lumen to muscularis mucosae, and within a 100 μm2 field surrounding an adjacent submucosal blood vessel.
As presented in the figures, non-parametric data was analyzed by Kruskal-Wallis test with Dunn's multiple comparisons test used to compare all groups to one another and individual pair-wise comparisons was analyzed by Mann Whitney U-Test. All statistical analyses were performed using GraphPad Prism 7 (La Jolla, Calif.).
The observed mortality rate was within the expected range given the design including surgical intervention, T-cell transfer in immunologically compromised animals followed by chronic development of colitis over a 6-week study period (Ostanin D V et al. Am J Physiol Gastrointest Liver Physiol. 2009, 296(2):G135-G146).
The survival of animals was compared; no significant difference in survival rate was found in treatments of anti-IL12p40 and anti-TNFα with either route of administration compared to vehicle or IgG controls (p>0.08, log-rank; Kaplan-Meier). The timing of animal deaths did not correspond to changes in efficacy endpoints, such as body weight, that were evaluated longitudinally. As noted above, changes in DAI score which includes, BW loss, stool consistency and colitis severity were carried forward to limit any bias that may be introduced by mortality.
The mean colon weight:length ratio was significantly elevated in vehicle control animals (Group 2) compared to naïve (Group 1); no other significant differences in mean colon weight:length ratio were observed.
The Disease Activity Index was determined in each mouse using a total score from the scoring system depicted in Table 38.
The data in
The concentration of inflammatory cytokines was evaluated in the colonic tissue in vehicle or IgG control groups.
A significant reduction of inflammatory cytokines, including IL 17A, IL-4, TNFα, and IL-22, were found in groups treated with anti-TNFα (IC (Group 8) or IP (Group 7)) when compared with vehicle (IP/IC) control or its respective IgG controls (IC or IP) in colon tissue (
A significant reduction of IL-22, IL-6, IL17A, TNFα, IL-1b, and IFNγ cytokine was found in groups treated with anti-IL12p40 (IP or IC) when compared with vehicle (IP/IC) control in colon tissue (
Treatments with either systemic (IP) or topical (IC) administration of an anti-TNFα antibody or anti-IL12p40 antibody led to a significant decrease in body weight (BW) loss over time from Day 0 to Day 42.
The change in body weight over the course of the experiment from Day 0 through Day 42 is shown in
Lesions of ileitis and colitis, including inflammation, crypt damage, occasional erosions, and epithelial hyperplasia, were induced with the T-cell transfer in this model. Lesions were the least severe in ileum sections and the most severe in the proximal colon. Both IP and IC administration of anti-IL12p40 and anti-TNFα resulted in a reduction in sum ileitis/colitis scores compared to PBS vehicle control. Targeted IC anti-TNFα treatment showed a significant improvement in the mean histopathologic score when compared with the vehicle controls given by either route (IP or IC) in proximal and distal colon tissues (
Targeted IC anti-TNFα treatment showed the greatest magnitude of lymphocyte reductions in all counted fields, from inner lumen to submucosa of proximal colon when compared to the vehicle control group (Group 8 vs. Group 2, P<0.05*,
Thus, significantly reduced body weight loss (%), decreased Disease Activity Index, improved histological score and reduced tissue inflammatory cytokines were found in animals receiving targeted (IC) anti-TNFα antibody when compared with vehicle controls. Targeted IC delivery was significantly more efficacious when compared to systemic (IP) anti-TNFα antibody in end points of total histologic score and lymphocyte count from inner lumen to submucosa of proximal colon.
The overall study design is summarized in Table 39. Briefly, at least 10 days prior to the start of the study (Day −10), a cohort of male C57BL/6 mice underwent surgical implantation of a cecal cannula. Colitis was induced in 110 mice (Groups 2-7) by exposure to 3% DSS-treated drinking water from Day 0 to Day 5. Five animals (Group 1) served as no-disease controls; the other animals received a single dose of vehicle (Group 2) or tofacitinib citrate suspension containing about 0.5% excipients via oral gavage (PO; Groups 3 and 4) or intracecal injection via the surgically implanted indwelling catheter (IC; Groups 5, 6 and 7) once on Day 12 (peak disease status). All animals were weighed daily and assessed visually for the presence of diarrhea and/or blood in stool. A subset of animals per group was sacrificed for terminal PK collections at various time points post-dose. Terminal samples (plasma, cecal contents, colon contents, cecal tissue and colon tissue) were collected at terminal sacrifice. All K2EDTA plasma and tissue homogenate (proximal colon, cecum and associated lumen contents) were stored at −80° C. until further analysis.
1All dose levels are expressed based on tofacitinib citrate salt form.
Plasma samples and tissue homogenate (proximal colon, cecum and associated lumen contents) were assessed for tofacitinib. Briefly, samples were analyzed by LC-MS/MS against matrix-matched standard curves. Three additional samples were above their respective quantitation limits, and extrapolated data was reported.
To evaluate pharmacodynamic (PD) effects of tofacitinib in the DSS-induced colitis mouse model, several cytokines involved in the JAK/STAT signaling pathway, i.e., IL-6, GM-CSF, IL-15, IL-2, IL-12, IL-13, TNF-α, and INF-γ, were measured in both plasma and colon tissue by ELISA.
The study design was complex and involved surgical procedure in a disease model The PK/PD parameters were derived from limited time points and should be considered best estimates only.
All PK/PD concentrations are expressed as active drug moiety (anhydrous tofacitinib free base).
PK modeling was performed using mean plasma or tissue concentrations of tofacitinib versus time curves. The following PK parameters were calculated with a one-compartmental model using Excel software: time to maximum concentration: Tmax; half-life: t1/2, maximum concentration: Cmax; clearance (Cl), area under the concentration-time curve from the start of dosing to the last protocol-specified time point: AUC(0-24h). The absolute oral bioavailability was estimated to be 74% based on: Xeljanz® (Tofacitinib tablets for oral administration) Prescribing Information Revised November 2012.
Animals dosed PO with tofacitinib citrate (Groups 3-4) demonstrated the highest mean plasma tofacitinib concentrations at all time points, while limited blood exposure was observed in animals treated IC (Groups 5-6) (See

Inflammatory cytokine IL-6 has been shown to play a critical role in the response of uncontrolled intestinal inflammation through JAK1/JAK2 and JAK1/TYK2 signaling pathways (Meyer et al. (2010) J. Inflamm. 7-41).
In plasma, inhibition of IL-6 expression was observed in groups treated with tofacitinib citrate via PO or IC administration at 1 h and 3 h post-treatment; recovery of IL-6 expression (50 to 100%) was observed at 12 and 24h post-treatment (data not shown).
In colon tissue, inhibition of IL-6 expression was sustained through 24 h post-dose in colon tissue in all IC treated groups and in the high dose PO group (45 mg/kg) (
The concentration of GM-CSF was not significantly different between the DSS-treatment groups and the naïve group, nor was there a significant difference in GM-CSF levels between IC and PO treatment groups in either plasma or colon tissue, despite high exposure of tofacitinib found in colon tissue of IC groups dosed at 3 and 10 mg/kg (data not shown).
