FIELD

The disclosure generally relates to ingestible devices capable of delivering a dispensable substance, such as a therapeutic agent, as well as related components, systems and methods.

BACKGROUND

The gastrointestinal (GI) tract generally provides a therapeutic medium for an individual's body. At times, it is desirable to dispense therapeutic agents to the GI tract to treat a medical condition.

SUMMARY

The disclosure provides ingestible devices that can directly deliver therapeutic agents to desired tissue(s) of the GI tract of a subject, such as the submucosa, the mucosa, and/or the mucus layer of the GI tract, and methods of using the same. The ingestible devices can deliver therapeutic agents in a safe, effective, and reliable manner. The disclosure also provides pharmaceutical compositions for use in methods of treating a disease or condition in a subject in need thereof.

Ingestible devices of the present disclosure are configured to provide at least three different modes of direct delivery of therapeutic agents to the GI tract of a subject, referred to herein as trans-epithelial, epithelial, and topical delivery. Direct delivery, as used herein, refers to a force-driven delivery mechanism.

Thus, in one aspect, this disclosure relates to trans-epithelial delivery of a therapeutic agent to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device that can directly deliver a therapeutic agent past the epithelial cell layer of the mucosa of the GI tract of a subject to yield systemic exposure of the therapeutic agent to the subject. In such embodiments, the ingestible device is configured to directly deliver the therapeutic agent past the epithelial cell layer of the mucosa and into the submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the GI tract, where it is available for systemic uptake. This can be particularly relevant when the oral bioavailability of the therapeutic agent is otherwise low. In some embodiments, systemic exposure of the therapeutic agent is achieved by trans-epithelial delivery of the therapeutic agent into the submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the small intestine, for example, in the duodenum, the jejunum, and/or the ileum. In further embodiments, the trans-epithelial delivery directly delivers the therapeutic agent into the submucosa submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the GI tract such that the percent systemic uptake of the trans-epithelial delivery relative to intravenous or subcutaneous administration is at least about 10% (e.g., at least about 15%, at least about 20%, at least about 25% or more).

Without wishing to be bound by theory, it is believed that trans-epithelial delivery to the submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the GI tract is achieved by using an appropriate value for one or more performance parameters associated with the ingestible device configured for such use. Such performance parameters include, for example, internal pressure of the ingestible device, peak fluid pressure of the ingestible device, nozzle pressure of the ingestible device, peak jet power of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet velocity of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet pressure of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet force of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet stable length of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, nozzle shape, nozzle length and nozzle diameter.

As an example, in some embodiments, the ingestible device is configured for trans-epithelial delivery and may provide/exhibit one or more of the following properties. The ingestible device is configured to deliver the dispensable substance to tissue of the GI tract of a subject at a peak jet power of from about one Watt to about three Watts. The ingestible device has a drive force generator that provides an internal pressure of from about 225 psig to about 400 psig. The ingestible device contains the dispensable substance at a peak fluid pressure of from about 200 psig to about 375 psig. The ingestible device is configured to deliver the dispensable substance at a peak jet velocity of from about 25 meters per second to about 45 meters per second. The ingestible device is configured to deliver the dispensable substance as a jet having jet stable length of at least about one millimeter. The ingestible device is configured to deliver the dispensable substance to tissue of the GI tract of a subject at a peak jet pressure of from about 100 psig to about 250 psig. The ingestible device is configured to deliver the dispensable substance to tissue of the GI tract of a subject at a peak jet force of from about 0.09 N to about 0.15 N. The ingestible device has one or more nozzles, each having a diameter of from about 0.1 millimeter to about two millimeters and/or a length of from about one millimeter to about five millimeters.

In another aspect, this disclosure relates to epithelial delivery of a therapeutic agent to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to directly deliver the therapeutic agent into the mucus and/or onto the epithelial layer, but not past the epithelial layer of the mucosa, of the small or large intestine, from which it can act locally, and in some cases away from the site of direct delivery. In some embodiments, the device is configured so that the therapeutic agent is delivered from the device with sufficient force to provide the epithelial delivery, the force being lower than that required for trans-epithelial delivery.

In yet another aspect, this disclosure relates to topical delivery of a therapeutic agent to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to deliver the therapeutic agent into the lumen and/or onto the mucus or other surface of the GI tract facing the lumen of the small or large intestine, from which it can act locally, and in some cases away from the site of delivery. In some embodiments, the device is configured so that the therapeutic agent is delivered from the device with sufficient force so that the therapeutic agent is delivered topically, the force being lower than that required for the epithelial or the trans-epithelial delivery.

The ingestible device, whether configured for trans-epithelial, epithelial or topical delivery, can have a streamlined and/or relatively simple mechanical design, be relatively small, and/or be inexpensive to manufacture. In general, the device protects a dispensable substance (e.g., a therapeutic agent, or a pharmaceutical formulation comprising the therapeutic agent) until the device reaches a desired location of the subject. As an example, the device can be designed to deliver dispensable substance to a desired location in the GI tract of a subject, and the device can be designed so that the dispensable substance is not subject to constituents of the GI tract (e.g., acids, enzymes) prior to reaching the desired location in the GI tract. As another example, the device can be designed to deliver dispensable substance such that the therapeutic properties of the dispensable substance are not altered during delivery (e.g., the dispensable substance is a therapeutic agent that binds its therapeutic target after delivery).

The present disclosure provides ingestible devices that can directly deliver therapeutic agents to desired tissue(s) of the GI tract of a subject (such as the submucosa, the mucosa, and/or the mucus layer of the GI tract), e.g., to treat a particular class of disease, or a specific disease. Relatedly, methods of using the device to deliver the therapeutic agents to desired tissue(s) of the GI tract, e.g., to treat a particular class of disease, or a specific disease, are disclosed. These disclosures also inherently provide disclosures of corresponding medical uses—that is, disclosures of the recited therapeutic agents for use in a method of treating the recited class of disease, or specific disease, by using the device to deliver the recited agents to desired tissue(s) of the GI tract of a subject.

DETAILED DESCRIPTION
Definitions

“Ingestible,” as used herein in reference to the device, means that the device can be swallowed whole.

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 an 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.

“Bioavailability,” as used herein, may be reported based on the ratio of the area under a curve (AUC) of the therapeutic agent concentration in systemic circulation versus time that is achieved when the drug is administered by another form of administration (e.g., trans-epithelial administration [hereinafter, AUC)_TE] or topical administration [hereinafter, AUC)_TOP], respectively) versus the AUC of the therapeutic agent concentration in systemic circulation versus time that is achieved when the same amount of the drug is administered intravenously [hereinafter, (AUC)_IV], or subcutaneously [hereinafter, (AUC)_SC], expressed as a percentage. In some aspects, especially when the pharmacokinetic data are derived from more than one subject, the AUC is a mean AUC. In some embodiments, the mean is a geometric mean. In other aspects, as used herein, drug exposure may be reported based on a different pharmacokinetic parameter. For example, drug exposure may be reported as a ratio of maximum therapeutic agent concentration (C_max) in systemic circulation that is achieved when the drug is administered by another form of administration (e.g., trans-epithelial administration [hereinafter, (C_max)_TE] or topical administration [hereinafter, (C_max)_TOP]), versus the C_maxof the therapeutic agent concentration in systemic circulation that is achieved when the same amount of the drug is administered intravenously [hereinafter, (C_max)_IV], or subcutaneously [hereinafter, (C_max)_SC], expressed as a percentage.

As used herein, “non-oral,” when used in reference to a therapeutic suitable for use with the devices and methods of the present disclosure, refers to a therapeutic or active agent that has poor bioavailability and/or is not administered by an oral route of administration.

The term “chemokine/chemokine receptor inhibitors” refers to an agent which decreases the ability of a chemokine to bind to its receptor, where the chemokine is one of CXCL10 (IL-10), CCL11, or an ELR chemokine, or the chemokine receptor is CCR2 or CCR9.

“Effective amount” as used herein refers to an amount of therapeutic agent that offers beneficial response to a patient receiving the treatment. For example, an effective amount may be a Human Equivalent Dose (HED). The phrase “therapeutically effective amount,” as used herein, refers to the amount of the therapeutic agent that is effective for producing a desired therapeutic effect. In some embodiments, a therapeutically effective amount treats or prevents a disease or condition disclosed herein.

“Mucosa-associated lymphoid tissue” or “MALT” used herein refers to a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, oral passage, nasopharyngeal tract, thyroid, breast, lung, salivary glands, eye, and skin.

“Gut-associated lymphoid tissue” or “GALT” as used herein refers to a part of the broader MALT and includes, e.g., Peyer's patches, mesenertic lymph nodes, and isolated lymphoid follicles/intestinal lymphoid aggregates.

“Peyer's patches” as used herein refers to aggregated lymphoid modules organized into follicles and are important part of GALT. Peyer's patches are mainly present in the distal jejunum and the ileum.

“Mesenteric lymph nodes” as used herein refers to part of the paraaortic lymph node system that is a group of lymph nodes that lie between the layers of the mesentery and drain the gut tissues and deliver lymph to the thoracic duct. Mesenteric lymph nodes include the “superior mesenteric lymph nodes” which receive afferents from the jejunum, ileum, cecum, and the ascending and parts of the transverse colon. Mesenteric lymph nodes also include “inferior mesenteric lymph nodes” which are lymph nodes present throughout the hindgut. The hindgut, e.g., includes the distal third of the transverse colon and the splenic flexure, the descending colon, sigmoid colon, and the rectum. The lymph nodes drain into the superior mesenteric lymph nodes and ultimately to the preaortic lymph nodes.

“Paraaortic lymph nodes” as used herein refers to a group of mesenteric lymph nodes that lie in front of the lumbar vertebrae near the aorta. The paraaortic lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. Paraaortic lymph nodes include, e.g., retroaortic lymph nodes, lateral aortic lymph nodes, preaortic lymph nodes (e.g., Celiac, gastric, hepatic, and splenic lymph nodes), superior mesenteric lymph nodes (e.g., mesenteric, ileocolic, and mesocolic lymph nodes), and inferior mesenteric lymph nodes (e.g., pararectal lymph nodes).

A drug's international nonproprietary name (INN), as used herein, 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, and the biosimilars thereof, and/or glycosylation variants thereof, in the case of biologics such as antibodies, 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, or a glycosylation variant thereof, whether or not such a biosimilar or glycosylation variant is expressly indicated.

“Dispensable” as used herein 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 a therapeutic agent as disclosed herein, and/or a formulation that includes a therapeutic agent as disclosed herein. A dispensable substance may be a fluid, such as a liquid, a suspension or a semi-solid. For example, a dispensable substance can be a liquid in the form of a solution, such as an aqueous solution. In some embodiments, when disposed in an ingestible device, a substance is a non-fluid, such as a solid. In such embodiments, the substance may be converted to a fluid prior to being delivered from the ingestible device. In some embodiments, the therapeutic agent is a small molecule. In other embodiments, the therapeutic agent is a large molecule, such as a biologic drug. Nonlimiting examples of biologic drugs include antibodies (including monoclonal antibodies), proteins (including fusion proteins), peptides (including cyclic peptides), cells (including stem cells), and nucleic acids (including inhibitory nucleic acids, antisense nucleic acids, siRNA, ribozymes). In some embodiments, the dispensable substance is a pharmaceutical formulation comprising a therapeutic agent and a liquid carrier. In some embodiments, the pharmaceutical formulation comprising the therapeutic agent and the liquid carrier is a solution formulation. In other embodiments, the pharmaceutical formulation comprising the therapeutic agent and the liquid carrier is a suspension formulation, or an emulsion formulation. In some embodiments, a dispensable substance delivered as described herein is particularly well-suited for treatment of diseases and conditions of the endoderm, for example, it may be more efficacious in gut-associated lymphoid tissue (GALT) or the hepatic system as compared to subcutaneous or intravenous administration. In general, the viscosity of a dispensable substance can be selected as appropriate. In some embodiments, the dispensable substance has a viscosity of at least about 0.5 centiPoise (cP) (e.g., at least about 0.8 cP, at least about 1 cP, at least about 2 cP, at least about 3 cP, at least about 4 cP, at least about 5 cP) and/or at most about 10 cP (e.g., at most about 9 cP, at most about 8 cP, at most about 7 cP). In certain embodiments the dispensable substance has a viscosity of from about 0.5 cP to about 10 cP (e.g., from about 0.8 cP to about 9 cP, from about 0.8 cP to about 8 cP).

As used herein, the term “enteric” refers a material that permits transition to a desired location in the GI tract (e.g., through the stomach to the intestine) before being dissolved/degraded/eroded due to exposure of certain conditions (e.g., pH, temperature, enzymes) of the GI tract. An enteric material may prevent a drug from degradation by gastric fluid and enzymes. In some embodiments, an enteric composition (e.g., when formed as a coating on the housing of an ingestible device) is selected from mixtures of fats and fatty acids; shellac and shellac derivatives; and cellulose acetate phthalates. An enteric material can be an enteric polymer. In some embodiments, an enteric polymer can remain insoluble in the stomach, but dissolve at the higher pH of the intestine (e.g., small intestine or large intestine), and are used to deliver drugs to the intestine. Examples include Colorcon's Opadry Enteric 91 series Polyvinyl Acetate Phthalate, Opadry Enteric 94 series Methacrylic Acid, Opadry Enteric 95 series Methacrylic Acid, Sureteric PVAP (Polyvinyl Acetate Phthalate), Nutrateric Ethylcellulose Evonik Acryl-EZE (Colorcon & Evonik collaboration—Eudragit L 100-55 Mixture Methacrylic copolymers); Evonik's Eudragit L 100-55 Methacrylic copolymers, Eudragit L 30 D-55 Methacrylic copolymers (30%), Eudragit L 100 Methacrylic copolymers, Eudragit L 12.5 Methacrylic copolymers (12.5%), Eudragit S 100 Methacrylic copolymers, Eudragit S 12.5 Methacrylic copolymers (12.5%), Eudragit FS 30 D Methacrylic copolymers (30%); Kerry's SheffCoat ENT Cellulose Acetate Phthalate, Acrylate copolymer, HPMC-P; Eastman's C-A-P NF Cellulose Acetate Phthalate; Sensient's PROTECT™ ENTERIC Shellac & Sodium Alginate. In certain embodiments, an enteric material dissolves in the small intestine and is suitable for small intestine release. Examples of such enteric materials include, but are not limited to, cellulose derivatives, e.g., cellulose acetate phthalate, hydroxypropylmethylcellulose phthalate (HPMCP), hydroxypropylmethylcellulose acetate succinate (HPMCAS) and RL100 (e.g., HP-55), malic acid-propane 1,2-diol, polyvinyl acetate phthalate, anionic polymers of methacrylic acid and methyl methacrylate, hydroxypropylcellulose acetate phthalate, polyvinyl acetate phthalate, methacrylate-methacrylic acid copolymers, styrol, maleic acid copolymers, shellac, and others. Another suitable enteric material is a water emulsion of ethylacrylate methylacrylic acid copolymer, or hydroxypropyl methyl cellulose acetate succinate (HPMAS). (See, e.g., U.S. Pat. No. 5,591,433). In some embodiments, an enteric material dissolves in the large intestine and is suitable for colonic release. Enteric materials suitable for large intestine (e.g., colonic) release are known to one of skill in the art. In some embodiments, degradation of the coating is microbially triggered, e.g., the bacteria in the colon enzymatically trigger degradation of the coating (see, e.g., Archana et al., Int. J. Pharm. Sci. Res. (2016) 1(5):40-47; and Sethi et al., Int. J. Pharm. Sci. Res. (2012) 3(9):2989-3000). In some embodiments, the coating is a pH-dependent polymer that is insoluble at low pH but becomes increasingly soluble as pH increases. In some embodiments, the coating is a polymethacrylates with a pH-dependent dissolution threshold of about pH 6.0 to about 7.0. Examples of suitable enteric materials include, but are not limited to, chitosan, alginates (e.g., as calcium salts), Eudragit® L (e.g., Eudragit® 100), Eudragit® S (e.g., Eudragit® S 100), Eudragit® L (e.g., Eudragit® L-30D), Eudragit® FS (e.g., Eudragit® FS 30D), hydroxypropylmethylcellulose phthalate 50, hydroxypropylmethylcellulose phthalate 55, and cellulose acetate trimellate. In some embodiments, an enteric material is a material described in U.S. Pat. No. 10,226,430; Sethi et al., Int. J. Pharm. Sci. Res. (2012) 3(9):2989-3000; or Archana et al., Int. J. Pharm. Sci. Res. (2016) 1(5):40-47, each of which are herein incorporated by reference in their entireties. In some embodiments, the colon-specific degradation of an enteric material can be based on the presence of microorganisms that reside only in the colon, more particularly, biodegradable enzymes produced by these microorganisms. In general, such microorganisms are anaerobic bacteria, e.g., Bacteroides, Bifidobacteria, Enterobacteria, Eubacteria, Clostridia, Enterococci, and Ruminococcus, etc. These micro floras fulfill their energy needs by fermenting various types of substrates that have been left undigested in the small intestine, e.g., polysaccharides, di- and tri-saccharides, etc. These polymers are stable in the environments of the stomach and small intestine. On reaching the colon, the polymers undergo degradation by the enzyme or break down of the polymer backbone leads to a subsequent reduction in their molecular weight and thereby loss of the mechanical strength.

General Introduction

FIG. 1A schematically describes the different regions of healthy intestinal tissue, presented in a cross section. The regions include the lumen of the GI tract, the mucus of the GI tissue, the mucosa of the GI tissue and the submucosa of the GI tissue. The mucosa of the GI tissue includes the epithelial layer and the lamina propria. The muscularis mucosae separates the mucosa from the submucosa. The muscularis extrema is below the submucosa. FIG. 1B schematically describes corresponding regions of diseased intestinal tissue, presented in a cross section.

An ingestible device described herein can deliver a therapeutic agent via topical delivery (without being directly delivered to the mucus, mucosa or submucosa), epithelial delivery (directly delivered to the mucus or epithelium without being directly delivered past the epithelial layer to the mucosa or submucosa) or trans-epithelial delivery (directly delivered to the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria.

In general, the form of delivery may depend on the design of the ingestible device and parameters used with the device (e.g., internal pressure, fluid pressure, number of nozzles, design of nozzles). Holding other parameters constant, at relatively low fluid pressures and/or internal pressures, the therapeutic agent may be topically delivered, while higher fluid pressures and/or internal pressures may result in epithelial delivery, and still higher fluid pressures and/or internal pressure may result in trans-epithelial delivery. During trans-epithelial delivery, a bolus of the therapeutic agent initially contained in the dispensable substance may form within the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria.

In some embodiments, the following holds. The ingestible device is designed to deliver a dispensable substance, for example, a therapeutic agent or a pharmaceutical formulation containing a therapeutic agent through the epithelial layer of the mucosa of the GI tract. In some embodiments, the dispensable substance is a solution formulation; optionally, a suspension. In some embodiments, the dispensable substance enters the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the small intestine, where it can be absorbed systemically. After the patient swallows the device, it passes through the GI tract and eventually reaches the small intestine. The device includes a restraining mechanism, an optionally a triggering mechanism (e.g., a degradable and/or erodible coating, such as an enteric coating, that partially or completely degrades and/or erodes when the device reaches the desired location in the GI tract). The desired location can be the small intestine or the large intestine. When the device is configured for trans-epithelial GI tract delivery to the submucosa submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, the preferred location can be the small intestine. With the restraining element is removed, relative movement between certain components (e.g., sliding of a component) occurs such that one or more openings in the ingestible device (e.g., in a compartment containing the dispensable substance, such as a reservoir, sometimes referred to herein as the “drug reservoir,” “storage reservoir” or “substance reservoir”) become aligned with one or more additional openings (e.g., one or more nozzles) in the ingestible device (e.g., in the housing). With the ingestible device now in this open position, a force (e.g., generated by a force generator and/or transferred by a drive coupling, such as a membrane or a piston) forces the dispensable substance from the drug reservoir out of the device via the one or more openings (e.g., the one or more nozzles). The dispensable substance is delivered as a jet of fluid (e.g., liquid) through the epithelial layer of the mucosa and directly into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract in the form of single or multiple boluses. After swallowing the device, the device travels through the GI tract (mouth, esophagus, stomach, duodenum, jejunum, ileum, cecum and colon), ultimately exiting the GI tract via the anus.

Thus, in general, the ingestible devices disclosed herein provide delivery of therapeutic agent to the GI tract of a subject. In one aspect, the disclosure relates to trans-epithelial delivery of a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device that can directly deliver a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract of a subject, which may result in systemic exposure of the therapeutic agent to the subject. In such embodiments, the ingestible device is configured to directly deliver the dispensable substance past the epithelial cell layer of the mucosa and into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract, where the therapeutic agent so delivered is available for systemic uptake. In some embodiments, systemic exposure of the therapeutic agent is achieved by trans-epithelial delivery of the dispensable substance into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the small intestine, for example, in the duodenum, the jejunum, and/or the ileum. In some further embodiments, the trans-epithelial delivery directly delivers the dispensable substance into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract such that the percent systemic uptake of the therapeutic agent via the trans-epithelial delivery relative to intravenous or subcutaneous administration is at least about 10% (e.g., at least about 15%, at least about 20%, at least about 25% or more).

In some embodiments, the direct delivery of the therapeutic agent to the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, via trans-epithelial delivery may also or alternatively provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery.

In some embodiments, the trans-epithelial delivery may directly deliver a first portion of the dispensable substance to the submucosa of the GI tract, and a second portion of the dispensable substance to the mucosa, all or a further portion of which may be directly delivered to the lamina propria. In some embodiments, the second portion of the dispensable substance delivered to the mucosa, such as the lamina propria, of the GI tract via the trans-epithelial delivery may provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery.

In another aspect, the disclosure relates to epithelial delivery of a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to directly deliver a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) into the mucus, but not past the epithelial layer of the mucosa, of the small or large intestine, from which it may provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery. In some further embodiments, the ingestible device directly delivers the dispensable substance such that it contacts the surface of the epithelial cell layer of the mucosa facing the lumen, but as previously noted, the epithelial delivery does not directly delivery the dispensable substance past the epithelial layer of the mucosa. In some embodiments, the device is configured so that the dispensable substance is delivered from the device with sufficient force to provide the epithelial delivery, the force being lower than that required for trans-epithelial delivery to the GI tract. In some further embodiments, the epithelial delivery directly delivers the dispensable substance into the mucus of the GI tract such that the percent systemic uptake of the therapeutic agent via the epithelial delivery relative to intravenous or subcutaneous administration is greater than that for topical delivery, but less than for trans-epithelial delivery. In other embodiments, the epithelial delivery directly delivers the dispensable substance into the mucus of the GI tract such that the percent systemic uptake of the therapeutic agent via the epithelial delivery relative to intravenous or subcutaneous administration is about 0.5% to about 10% or more (e.g., about 0.5%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, or more).

In some embodiments of epithelial delivery, the therapeutic agent directly delivered into the mucus of the GI tract via the epithelial delivery may undergo active or passive transport or diffusion past the epithelial layer. Once past the epithelial layer, the therapeutic agent may provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery. In some embodiments, the therapeutic agent binds to a therapeutic target present in the GI epithelial layer or elicits other pharmacodynamic effects locally or away from the site of delivery via immune cells or tissue in the GI tract (e.g., dendritic cells, lymphocytes, mucosa-associated lymphoid tissue).

In yet another aspect, this disclosure relates to topical delivery of a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to deliver the dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) into the lumen and/or onto the mucus or other surface (e.g., a diseased surface) of the GI tract facing the lumen of the small or large intestine, from which it may provide therapeutic effects locally and/or away from (e.g., distal to) the site of delivery. In some embodiments, the device is configured so that the dispensable substance is delivered from the device with sufficient force so that the dispensable substance is delivered topically, the force being lower than that required for the epithelial or the trans-epithelial delivery to the GI tract. In some embodiments, the topical delivery to the GI tract results in reduced systemic uptake of the therapeutic agent compared to trans-epithelial delivery to the GI tract, intravenous or subcutaneous delivery.

In some further embodiments, topical delivery delivers the dispensable substance into the lumen and/or onto the mucus or the other surface facing the lumen of the GI tract such that the percent systemic uptake of the therapeutic agent via the topical delivery relative to intravenous or subcutaneous administration is less than about 20%, less than about 10%, less than about 5%, less than about 4%, less than about 3%, less than about 2% or less than about 1%. In some embodiments, the topical delivery to the GI tract results in negligible or no systemic uptake of the therapeutic agent compared to trans-epithelial delivery to the GI tract, intravenous or subcutaneous delivery.

In some embodiments, the topically delivered dispensable substance may spread over the mucus or other surface facing the lumen of the GI tract, thereby coating the surface of the GI tract at or away from (e.g., distal to) the site of delivery. In some embodiments, upon or after the dispensable substance has been topically delivered, the therapeutic agent may undergo transport (e.g., diffusion) from the surface of the mucus into the mucus, and optionally, active or passive transport or diffusion past the epithelial layer of the mucosa. In some embodiments, the mucus and/or epithelial layer of the mucosa may be disrupted or even absent, such as in a patient having a disease or condition of the GI tract.

In such embodiments, the topical delivery of the dispensable substance to the GI tract of the patient may provide direct delivery of the dispensable substance to the surface of the GI tract facing the lumen, such as mucosal tissue exposed by said disruption and/or absence (e.g., both the mucus layer and/or epithelial layer are completely or partially absent or compromised in portions of the GI tract due to a disease or condition). For example, in some embodiments, the topical delivery of the dispensable substance to the GI tract of the patient may provide topical delivery to one or more lesions of the GI tract. In some embodiments, the disease or condition is an inflammatory bowel disease. In some further embodiments, the inflammatory bowel disease is ulcerative colitis. In some other embodiments, the inflammatory bowel disease is Crohn's disease.

Accordingly, provided herein are new systemic delivery devices and methods that deliver therapeutic agents into the small intestinal mucosa and/or submucosa by jet injection. Current methods of administration for most large molecule therapeutic agents are subcutaneous (SC), intramuscular (IM), or bolus intravenous (IV) injection targeting the systemic circulation. The devices and methods described herein provide an alternative route of administration to current injectable medications, which can lead to greater convenience and compliance since they minimize or avoid the logistical challenges, patient compliance and adherence challenges, pain, and discomfort associated with traditional routes of administration.

Also, by providing a higher concentration of therapeutic in GI tissue, the devices and methods described herein are particularly well-suited for treatment of diseases and conditions of the endoderm, including the liver.

In some embodiments of any of the devices or methods described herein, the pharmaceutical composition is an ingestible device, that includes: a housing; a drug reservoir located within the housing and containing the therapeutic; a pre-pressurized air reservoir; a sliding mechanism; and an exit nozzle configured to allow the therapeutic agent to be released out of the housing from the reservoir and into the submucosa and/or the mucosa (e.g., into the lamina propria) of the gastrointestinal tract.

Device Description
General

In general, the ingestible device is suitable for swallowing by a patient and for safely and effectively passing through the GI tract of the patient. Generally, the device can be in the shape of a capsule, a pill or any other swallowable form that may be orally consumed by the subject. In some embodiments, the ingestible device can be swallowed voluntarily under medical supervision or in a home use environment with instruction provided ahead of subsequent ingestion. Generally, ingestible devices are intended for single subject, single use. The ingestible device can have a density high enough to cause the ingestible device to sink within human stomach fluid, e.g., the unfilled ingestible device can have a density of greater than 1.01 g/cm³. The ingestible device can have maximum dimensions that allow the ingestible device to pass through an average human GI tract. In some embodiments, the ingestible device is configured to prevent tumbling in the small intestine of a human. For example, the ingestible device is of sufficient length whereby it will not tumble in the small intestine of a human before, during, or after the dispensable substance is released. Generally, the ingestible device is configured to deliver a sufficient amount of therapeutic agent contained in the dispensable substance to be effective for its intended purpose. In general, the ingestible device's patient-contacting portions (e.g., exterior surface) and dispensable substance-contacting portions are biocompatible. Preferably, the device can withstand an indirect bite force without damaging the housing damage or resulting in leakage. As an example, when containing the dispensable substance, the ingestible device can withstand a bite force of at least about 60 Newtons (N). Generally, unless otherwise intended (see discussion below) components of the ingestible device can withstand exposure to a pH range expected in the human GI tract without substantial loss of functionality, substantial structural damage, or substantial leakage. As an example, in some embodiments, the ingestible device can withstand submersion in a pH 1.5±0.5 fluid environment for at least about 24 hours without substantial loss of functionality, substantial structural damage, or substantial leakage. In general, the ingestible device can maintain an external fluid barrier between the inside of the ingestible device and the GI tract of the subject during transit therethrough. Generally, the ingestible device can withstand external fluid pressures to which it is exposed during use without substantial loss of functionality, substantial structural damage, or substantial leakage. As an example, in some embodiments, the ingestible device undergoes no substantial loss of functionality, substantial structural damage, or substantial leakage when exposed to a sustained pressure of at least about 2 psig for at least about 24 hours and/or when exposed to a momentary pressure of at least about 5 psig momentary pressure for at least about 1 minute.

In general, an ingestible device disclosed herein includes the following features.

Housing

In some embodiments, the ingestible device comprises a housing configured to maintain its mechanical integrity during use of the ingestible device. In some embodiments, the housing has a first portion and a second portion. In some further embodiments, the housing has a first actuation component on the housing, and a second actuation component within the housing. In some embodiments, a storage reservoir is located within the housing, wherein the storage reservoir is configured to store a dispensable substance. In some embodiments, the housing has an opening in fluid communication with the storage reservoir. In some embodiments, the ingestible device employs an electrolytic mechanism for creating one or more openings in the ingestible device, wherein a substance can be dispensed through said opening as described in PCT Application Number PCT/US2019/021814, which published as WO2019178071, and which is incorporated by reference herein. For example, the housing may comprise an external electrolytic circuit (electrolytically erodible surface being on the exterior of the device), whereby the surrounding gastric fluids are the electrolyte that completes an electrolytic circuit between anode and cathode. With sufficient bias voltage (e.g., 1.5-15 volts, such as 3-5 volts), the anode will dissolve or erode electrolytically and thus create an opening in the housing within a desired time interval. In some embodiments, the one or more openings created by an electrolytic mechanism are coupled to one or more nozzles, thereby allowing for trans-epithelial, epithelial, or topical delivery as described herein. In some embodiments an ingestible device includes an enteric coating on the housing. In certain embodiments, the enteric coating covers only certain regions of the housing. The housing 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. 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 certain embodiments, these materials may further include liquid silicone rubber material with a hardness level of 10 to 90 as determined using a durometer (e.g., MED-4942™ manufactured by NuSil™), a soft biocompatible polymer material such as, but not limited to, polyvinyl chloride (PVC), polyethersulfone (PES), polyethylene (PE), polyurethane (PU) or polytetrafluoroethylene (PTFE), and a rigid polymer material coated with a biocompatible material that is soft or pliable (e.g., a poly(methyl methacrylate) (PMMA) material coated with silicone polymer). Use of different materials for different components may enable functionalization of certain surfaces for interaction with proteins, antibodies, and other biomarkers. For example, Teflon® may be used as a material in the ingestible device for movable components in order to reduce friction between these components. Other example materials may include other materials commonly used in micro-fabrication, such as polydimethylsiloxane (PDMS), borosilicate glass, and/or silicon. Although specific materials may be referred to herein as being used to construct the device for illustrative purposes, the materials recited are not intended to be limiting, and one skilled in the art may easily adapt the device to use any number of different materials without affecting the overall operation or functionality of the device. In some embodiments, the housing of the ingestible device may be manufactured from a type of plastic, such as a photosensitive acrylic polymer material or an inert polycarbonate material. The housing may also be formed using material that can be sterilized by chemicals. In some embodiments, the wall of the housing may have a thickness of, for example, from about 0.5 millimeter to about 1 millimeter. In some embodiments, in addition to being biocompatible, the material from which the housing is made is non-ferric and non-magnetic. Such materials include various plastics (e.g., PVC, or polycarbonate). Optionally, the housing can include a metal-based material, such as an alloy, stainless steel or a substantially pure metal. Such materials can be sterilized without affecting the mechanical workings of the ingestible device or the exterior surface of the ingestible device. In some embodiments, the metal-based material is compatible with the dispensable substance over long duration of storage. A wide variety of stainless steel alloys satisfy these criteria, including SAE grades 303, 304, 304L, 316, 316L, 440. In consideration of nickel content, purity, and/or traceability, in some embodiments, the stainless steel grade is approved for use as a surgical implant material, such as ASTM grades F138, F1314, F1586, F2229, or F2581. The walls of the housing of the ingestible device generally are sufficiently thick to withstand internal and external pressures to which they are exposed without substantial loss of functionality, substantial structural damage, or substantial leakage. In general, the walls of the housing are desirably as thin as possible to enhance the volume available for containing dispensable substance. As an example, in some embodiments, the walls are from about 0.05 mm to about 0.5 mm thick (e.g., if made of metal-based material, such as stainless steel) or from about 0.1 to about 1 mm thick (e.g., if made of plastic, such as polycarbonate). In general, the housing is made of material with a thermal expansion coefficient low enough that the device does not substantially deform at temperatures encountered during shipping and storage, or within the GI tract. In some embodiments, the walls of the housing are made of an electrolytically erodible surface as described in PCT/US2019/021814, which published as WO2019178071. For example, in some embodiments, the housing includes an electrolytically erodible valve coupled to a nozzle for exposing the liquid volume to its surrounding environment. The exposed metal anode material acting as valve can include a metal alloy or substantially pure metal that is acceptable for human ingestion from consideration of its biocompatibility in the amounts electrolyzed during opening of the valve. It can be desirable to have the thickness of metal in the valve area be small (e.g., to reduce the time and amount of current used to open the valve). For example, the metal portion of the drug container can be 0.025 mm thick across a diameter that matches or slightly exceeds the diameter of the coupled nozzle (e.g., 0.60 mm). In general, the thickness of the metal in the valve area can be in the range 0.002 mm to 0.200 mm.

In some embodiments, the housing of an ingestible device is assembled from multiple modules. For example, in some embodiments, the housing is assembled from two modules. In such embodiments, one of the modules can contain the dispensable substance (“drug module”), and the other module can contain the drive force generator and the drive coupling (“drive module”). Typically, the drug module includes a housing part of appropriate size, shape and material(s) as discussed herein. Usually, the housing part is sterilized, and dispensable substance is subsequently disposed within the housing under aseptic conditions. Optionally a sterile seal (e.g., a sterile foil seal) is incorporated into the drug module. The components of the drug module (e.g., a housing part, a drive force generator, a drive coupling) are assembled in a clean environment. The drug module and the drive module are subsequently combined to form the ingestible device. Representative examples of modules, their separate assembly, and their combination to form an ingestible device, are provide elsewhere herein.

Generally, an ingestible device is sized and shaped for relatively safe and effective movement and intended use within the GI tract of the subject. In certain embodiments, an ingestible device is a capsule having an industry standard size. For example, in some embodiments, an ingestible device is configured as a 00 capsule or a 000 capsule. In certain embodiments, the housing of an ingestible device has a length of at least about 20 mm (e.g., at least about 21 mm, at least about 22 mm, at least about 23 mm) and/or at most about 28 mm (e.g., at most about 27 mm, at most about 26 mm).

In certain embodiments, the housing of an ingestible device has an aspect ratio (ratio of length to width) of at least about 0.75 (e.g. at least about 1) and/or at most about 4 (e.g., at most about 3, at most about 2). In some embodiments, the housing of an ingestible device has an aspect ratio of from about 0.75 to 4 (e.g., from about 1 to about 3, from about 1 to about 2). For example, in some embodiments, the housing aspect ratio is about 1.5:1 (length:diameter). In some other embodiments, the housing aspect ratio is about 2:1 (length:diameter).

In certain embodiments, the housing of an ingestible device has a wall thickness of at least about 0.05 mm (e.g., at least about 0.5 mm, at least about 0.6 mm, at least about 0.7 mm) and/or at most about 1 mm (e.g., at most about 0.9 mm, at most about 0.8 mm). In certain embodiments, an ingestible device has a wall thickness of from about 0.05 mm to about 0.5 mm. In some embodiments, an ingestible device has a wall thickness of from about 0.1 mm to about 1 mm. In certain embodiments, one region of the housing of an ingestible device may have a wall thickness that is different from that of a different region of the housing of the ingestible device.

In some embodiments, the housing of an ingestible device has an end round that is spline-shaped or that is spherical. In certain embodiments, an ingestible device has an end round that is from about 1 mm to about 2 mm (e.g., about 1.5 mm). In some embodiments, an ingestible device has an end round that is from about 4 mm to about 4.5 mm (e.g., about 4.25 mm). In certain embodiments, an ingestible device has an end round that is from about 4.9 to about 5 mm (e.g., about 4.95 mm). In some embodiments, an ingestible device has an end round that is from about 5.4 mm to about 5.6 mm (e.g., about 5.5 mm).

In certain embodiments, the housing of an ingestible device has an internal volume of at least about 700 μL (e.g., at least about 750 μL, at least about 800 μL, at least about 850 μL) and/or most about 1700 μL (e.g., at most about 1650 μL, at most about 1600 μL, at most about 1500 μL, at most about 1400 μL, at most about 1300 μL, at most about 1200 L).

Fluid Volume

The ingestible device includes a fluid volume to contain a dispensable substance (e.g., a liquid, a suspension). In some embodiments, the fluid volume is completely disposed within the housing. Optionally, the fluid volume can be defined by a storage reservoir. Such a storage reservoir can be a component that can be prepared separately from the housing. In such a storage reservoir, the dispensable substance can be disposed in the storage reservoir before the storage reservoir is associated with the ingestible device.

Dispensable Substance

The device may include one or more dispensable substances, with each dispensable substance including one or more therapeutic agents and/or one or more pharmaceutical formulations including one or more therapeutic agents.

Nozzles

In some embodiments, an ingestible device includes one or more nozzles in fluid communication with the one or more openings in the ingestible device. The nozzle(s) is(are) configured so that the dispensable substance through the nozzle(s) when the dispensable substance is delivered from the ingestible device. In general, a nozzle can have any desired size and shape appropriate for the desired type of delivery of a dispensable substance from the ingestible device. In certain embodiments, a nozzle has a shape and/or size appropriate for trans-epithelial delivery, epithelial delivery or topical delivery. In some embodiments, an ingestible device includes more than one nozzle. For example, an ingestible device can include, for example, up to 50 nozzles (e.g., up to 40 nozzles, up to 35 nozzles, up to 30 nozzles, up to 25 nozzles, up to 20 nozzles, up to 15 nozzles, 10 nozzles). In some embodiments, an ingestible device includes from 2 nozzles to 50 nozzles. In certain embodiments, an ingestible device includes 2 nozzles, three nozzles, four nozzles, five nozzles, six nozzles, seven nozzles, eight nozzles, 10 nozzles, 20 nozzles, 30 nozzles, 36 nozzles, 40 nozzles, 50 nozzles). In some embodiments, the nozzles are arranged at even intervals (optionally pair-wise if an even number of nozzles are used) around the circumference of the device.

Restraining Mechanism

In some embodiments, the ingestible device comprises a restraining mechanism. Generally, a restraining mechanism has a first state in which it is configured to prevent the dispensable substance from exiting the ingestible device via the opening(s), and a second state in which it is configured so that it does not prevent the dispensable substance from exiting the ingestible device via the opening(s). The restraining mechanism can be configured to transition from its first state to its second state when it is exposed to a triggering condition. The restraining mechanism may be provided by one or more restraining elements. The restraining elements can have a first state in which they are configured to prevent the dispensable substance from exiting the ingestible device via the openings, and a second state in which they are configured to allow the dispensable substance to exit the ingestible device via the openings. The restraining elements can be configured to transition from the first state to the second state when the restraining elements are exposed to a triggering condition. In some embodiments, the restraining elements comprise a first type of restraining element and a second type of restraining element different from the first type of restraining element. The first type of restraining element can be configured to transition to its second state before the second type of restraining element transitions to its second state. In some embodiments, a restraining elements comprises a lid, a pin, a band, a plug, a dowel, a clasp, a clamp, a flange, a rivet, or any combination thereof. In some embodiments, the restraining elements comprise a plasticizer such as triethyl citrate (TEC). In some embodiments, the restraining elements comprise a degradable and/or erodible material, such as, for example, an enteric material. The enteric material may be degradable and/or erodible in the small intestine of the GI tract, or may be degradable and/or erodible in the large intestine of the GI tract, for example, the colon. In some embodiments, a restraining mechanism can be a mechanism that prevents the dispensable substance from being delivered from the ingestible device even when the drive force generator (or optionally the drive coupling) applies an internal force. For example, such a restraining can be an element (e.g., a pin, a band, a plug) in the opening (e.g., nozzle opening) through which the dispensable substance can be delivered from the ingestible device. Such a restraining element can be formed, for example, of a material that degrades and/or erodes as discussed above.

Triggering Mechanism

In some embodiments, the ingestible device comprises a triggering mechanism. In some embodiments, a triggering mechanism is configured to cause the dispensable substance within the fluid volume to be released under one or more triggering conditions. In some embodiments, a triggering mechanism initiates a drive force generator. In some embodiments, a triggering mechanism incorporates a mechanical feature like a restraining mechanism. As an example, one or more restraining elements degrade and/or erode in the presence of certain GI tract conditions (e.g., pH greater than 5), thereby triggering a drive force generator, such as a compressed spring. As another example, a spring may have a piercing element that pierces a cylinder with compressed gas, whereby the released gas acts as a force applied to a dispensable substance. In certain embodiments, a triggering mechanism incorporates an electrical feature. For example, an enteric coating degrades and/or erodes in the presence of certain GI tract conditions (e.g., pH greater than 5), thereby exposing conductors to intestinal fluid, which acts as a liquid conductor to triggering the drive force generator. In some embodiments, a triggering condition relates to a condition of the GI tract. In some embodiments, the condition of the GI tract comprises at least one condition selected from the group consisting of temperature, pH, presence of one or more enzymes, and time. In some more particular embodiments, the condition of the GI tract is a pH of greater than 5. In certain embodiments, the triggering mechanism is configured so that the release mechanism is autonomously triggered (e.g., due to degradation, dissolution and/or erosion of the restraining mechanism due to conditions in the GI tract).

In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is triggered by one or more of: a pH in the jejunum of about 6.1 to about 7.2, a pH in the mid small bowel of about 7.0 to about 7.8, a pH in the ileum of about 7.0 to about 8.0, a pH in the right colon of about 5.7 to about 7.0, a pH in the mid colon of about 5.7 to about 7.4, or a pH in the left colon of about 6.3 to about 7.7, such as about 7.0.

Drive Force Generator

The drive force generator is configured to provide the requisite force to the dispensable substance such that, when the restraining mechanism is removed, the dispensable substance is delivered from the ingestible device as desired. The drive force generator can apply force using different mechanisms, including, for example, a compressed gas, a gas generated by chemical reaction, a spring, a liquid-gas mixture, an impact ram, a sudden expansion caused by a controlled exothermic reaction, or the like. When the drive force generator is a spring, the spring can have one or more of the following properties: the outer diameter of the spring is smaller than the inner diameter of the ingestible device; the compressed length of the spring is minimized to leave more space for dispensable substance; the spring is of a conical shape, potentially with a reduction in the solid length of the spring; the free length of the spring is maximized and larger than the free length of the inner cavity of the ingestible device to ensure an acceptable driving pressure is provided throughout the entire time step of delivery; and the spring rate is large enough to provide acceptable pressure from the beginning until the end of delivery of the dispensable substance. Examples of springs include parallel springs, wave springs and conical springs. Examples of chemical reactants include an airbag inflator, a hydrogen cell (e.g., a Varta hydrogen cell), sodium bicarbonate and acid (e.g., alka seltzer and water on board the ingestible device, alka seltzer and GI tract fluid). Examples of compressed gas include a gas charged within the ingestible device, and a container (e.g., cylinder) of compressed gas. In some embodiments, the compressed gas is a gas cylinder from Picocyl. Exemplary gas cylinders are disclosed, for example, in US 2017-0258583, which is incorporated by reference herein. An example of a liquid-gas mixture is liquid nitrogen/HFA (hexafluoroacetone)/propane. An example of an impact ram is a two-phase spring/ram. Other examples of drive force generators include a wax actuator, heat generated by electric power (Peltier effect-based mechanism), and a mechanical puncture of tissue followed by delivery.

Drive Coupling

In general, the drive force coupling transfers a force from the drive force generator to the dispensable substance. Examples of a drive coupling include a piston and a membrane. Examples of membranes include balloons and elastomeric materials. An example of a piston is an O-ring sealed piston. In some embodiments, a piston is provided by a gas cylinder, e.g., with added O-rings or a custom housing. In some embodiments, a drive coupling is a vein, such as a rotating vein. In certain embodiments, a drive coupling is a double piston configured to counteract cap impact. In certain embodiments, a drive coupling is a collapsing bag, such as a collapsing foil bag. In some embodiments, a drive coupling is a collapsing bellows.

Storage Reservoir

In some embodiments, an ingestible device includes a storage reservoir configured to store a dispensable substance. In some embodiments, the storage reservoir stores the dispensible substance. In some embodiments, the storage reservoir is completely disposed within the housing.

FIG. 2 is a schematic representation of an ingestible device 200 which includes a housing 202, a fluid volume 204 containing a dispensable substance, a nozzle 206 with a nozzle opening 208, a restraining mechanism 210, a triggering mechanism 212, a drive force generator 214 and drive coupling 216. During use, ingestible device 200 is swallowed by a subject and traverses the GI tract. At an appropriate location, the triggering mechanism 212 is triggered, allowing the drive force generator to apply pressure to the drive coupling 216, which then applies pressure to the fluid volume such that at least some of the dispensable substance is delivered out of fluid volume 204, through the nozzle 206, and out of the device 200 via the nozzle opening 208. In some embodiments, the internal pressure is applied, even before the triggering mechanism 212 is triggered. As an example, at an appropriate location, the triggering mechanism 212 is triggered, allowing the drive coupling 216 to apply pressure to the fluid volume 204. In certain embodiments, the internal pressure is not applied until the triggering mechanism 212 is triggered.

Device for Trans-Epithelial Delivery

Generally, trans-epithelial delivery can be achieved at any desired location within the GI tract of a subject. In some embodiments, trans-epithelial delivery is achieved in the small intestine of the subject, such as, for example, in the duodenum, the jejunum and/or the ileum. In certain embodiments, trans-epithelial delivery is achieved in the large intestine of the subject, such as, for example, the cecum or the colon.

In certain embodiments, an ingestible device for trans-epithelial delivery has from 1 to 8 openings for delivery of dispensable substance (e.g., from 2 to 4 openings for delivery of dispensable substance, 2 opening for delivery of dispensable substance). In some embodiments, an ingestible device for trans-epithelial delivery has one or more nozzles, with each nozzle having a nozzle opening for delivering dispensable substance.

In one example, an ingestible device with a nozzle having a nozzle diameter of 0.35 mm diameter and containing a dispensable substance at a peak fluid pressure of 150 psig can deliver a jet of the dispensable substance at an average jet velocity of about 20 m/s and at an average jet impact pressure of about 29 psig.

In another example, an ingestible device having a nozzle pressure of 300 psig can deliver a dispensable substance at an average jet velocity of about 27 m/s and an average jet impact pressure of about 58 psig. In some embodiments, such an arrangement results in piercing of the intestinal wall.

In another example, an ingestible device having a nozzle with a nozzle diameter of 0.35 mm diameter and containing a dispensable substance at a peak fluid pressure of 320 psig can deliver a jet of the dispensable substance having an average jet velocity of about 28 m/s and an average jet impact pressure of about 62.4 psig.

FIG. 3 shows cross sectional views of a representative ingestible device 400 for trans-epithelial delivery, schematically illustrating certain parameters and components of action for the device 400. These include a drive force generator 42 which applies a force (resulting in an internal pressure) to a drive coupling 44. The drive coupling 44 transfers force from the force generator 42 to a fluid volume 46 containing a dispensable substance (e.g., a liquid, a suspension). The force applied to the fluid volume 46 by the drive coupling 44 generates pressure in the fluid volume 46 (fluid pressure). The pressure in the fluid volume 46 generates high-speed flow through an open nozzle 48 to produce a jet 50 of fluid at the nozzle outlet 52 that has a nozzle diameter 72 and the nozzle has a nozzle length 74.

During trans-epithelial delivery, the fluid jet 50 has a jet stable length 54 that is sufficient for the fluid jet 50 to travel across a nozzle stand-off distance 56 to reach the interface of the lumen of the GI tract and the surface of the GI tract facing the lumen. Ultimately, the fluid (e.g., liquid, suspension) impacts the mucosal layer of the GI tract (e.g., the epithelial layer and any mucus that may be present on the epithelial layer) as a stable stream of fluid with little breakup into a spray and is deposited in the submucosal and/or the mucosal tissue 58. That is, between the nozzle outlet 52 and the site of impact at the mucosa, the jet 50 has a jet diameter 76 that can vary in the manner discussed above with respect to the average jet diameter.

The fluid volume 46 experiences a peak fluid pressure 60 that generates the fluid jet 50 that exits the device 40 with a peak jet velocity, and impacts the interface of the lumen of the GI tract and the surface of the GI tract facing the lumen with a peak jet power, peak jet pressure and peak jet force. One of ordinary skill in the art recognizes that these three parameters are interconnected.

The pressure in the fluid volume 46 decreases during delivery so that the fluid pressure during delivery 70 varies, as does the jet power, jet force, and jet pressure. The fluid pressure during delivery 70 maintains the fluid jet 50 at sufficient jet impact force during delivery to continue fluid (dispensable substance including one or more therapeutic agents) delivery from the fluid volume 46 into the submucosal and/or mucosal tissue 58. The surrounding tissue can then absorb the delivered therapeutic agents for systemic delivery of the therapeutic agent.

Even prior to when the subject swallows the ingestible device, the drive coupling 44 transmits force from the force generator 42 to the fluid volume 46. The drive coupling 44 is prevented from moving by a restraining mechanism 80 (e.g., a pin or plug that selectively degrades and/or selectively erodes) until movement of the drive coupling is triggered by a triggering mechanism, and/or an opening becomes open.

FIGS. 4A-5B show cross sections of an example ingestible device 100.

FIG. 4A shows an exterior view of the ingestible device 100. The device 100 is generally cylindrical with a longitudinal axis and a generally smooth exterior surface 102. The exterior surface 102 includes a bottom housing 104 with an inlet 106 at one end, and a slider 108 (shown transparent) at the opposite end from the inlet 106 (e.g., a pressurization inlet port). The device 100 is a purely mechanical device for the delivery of a therapeutic agent to the GI tract, and does not contain any electronics.

FIG. 4B shows an embodiment of the device 100. The device 100 includes a gas reservoir 112, a dispensable substance reservoir 114 that contains the substance to be dispensed (e.g., a pharmaceutical formulation), a slider 108, degradable and/or erodible elements 116 (e.g., shear pins), and structural elements 118 (e.g., structural shear pins). In general, the degradable and/or erodible elements 116 are configured to degrade and/or erode under certain conditions, while the structural elements 118 are configured to provide additional mechanical strength beyond that provided by the degradable and/or erodible elements 116. Together, the degradable and/or erodible elements 116 and structural elements 118 are able to hold back the force of the force generator (e.g., a pressurized gas within the gas reservoir 112). However, when the degradable and/or erodible elements 116 begin to or completely degrade and/or erode in the presence of GI fluid, the structural elements 118 cannot alone hold back the force of the force generator (e.g., the pressurized gas), and the slider 108 moves to the open position. In some embodiments, the degradable and/or erodible elements 116 and structural elements 118 are placed in pairs with like elements on opposite sides of the device. In some embodiments, the degradable and/or erodible elements 116 are made of an enteric material. For example, the enteric material may be degradable and/or erodible in the small intestine of the GI tract, or the enteric material may be degradable and/or erodible in the large intestine of the GI tract, such as the colon. Although shown in FIGS. 2A-4B as including both the degradable and/or erodible elements 116 and the structural elements 118, in some embodiments, the device 100 includes the degradable and/or erodible elements 116 but does not include the structural elements 118.

FIGS. 4A-5B show cross sections of an embodiment of the device 100, which includes gas reservoir 112, a dispensable substance reservoir 114 that contains the substance to be dispensed (e.g., a pharmaceutical formulation), a slider 108, degradable and/or erodible elements 116 (e.g., shear pins), and structural elements 118 (e.g., structural shear pins). In general, the degradable and/or erodible elements 116 are configured to degrade and/or erode under certain conditions, while the structural elements 118 are configured to provide additional mechanical strength beyond that provided by the degradable and/or erodible elements 116. Together, the degradable and/or erodible elements 116 and structural elements 118 are able to hold back the force of the force generator (e.g., a pressurized gas within the gas reservoir 112). However, when the degradable and/or erodible elements 116 begin to or completely degrade and/or erode in the presence of GI fluid, the structural elements 118 cannot alone hold back the force of the force generator (e.g., the pressurized gas), and the slider 108 moves to the open position. In some embodiments, the degradable and/or erodible elements 116 and structural elements 118 are placed in pairs with like elements on opposite sides of the device. In some embodiments, the degradable and/or erodible elements 116 are made of an enteric material. For example, the enteric material may be degradable and/or erodible in the small intestine of the GI tract, or the enteric material may be degradable and/or erodible in the large intestine of the GI tract, such as the colon. Although shown in FIGS. 2A-4B as including both the degradable and/or erodible elements 116 and the structural elements 118, in some embodiments, the device 100 includes the degradable and/or erodible elements 116 but does not include the structural elements 118.

As shown in FIGS. 4A-5B, the ingestible device 100 is encased by a coating 120, such as a degradable and/or erodible coating, for example, an enteric coating, that covers the exterior surface 102. Optionally, the ingestible device 120 does not include the coating 120. Further, in certain embodiments, only certain portions of the ingestible device 100 include the coating 120. As an example, in some embodiments, only the pockets 124 (described below) are coated, e.g., coated with a degradable and/or erodible material, for example, an enteric material.

FIGS. 4B and 4C show the device 100 in its open position, where the substance reservoir 114 is fluidly connected to the outside of the device via the nozzles 122 (visible in FIG. 3C). To prepare the device for use, the dispensable substance (e.g., a therapeutic agent or a pharmaceutical formulation containing a therapeutic agent) is loaded into the substance reservoir 114 via the nozzles 122 with the device in this open position. Once the dispensable substance is loaded into the substance reservoir 114, the slider 108 is shut by sliding it axially, disconnecting the nozzles 122 from the exterior of the device so that the device 100 is in its closed position. Note that the location of the structural elements 118 and elements 116 are depicted in FIGS. 4B and 4C as these elements are not yet on the device 100 while it is in the open position depicted. The device 100 may also include a guide pin that provides alignment of nozzles 122 to the hole provided by the slider 108, and may also prevent the slider from continuing to translate axially.

FIGS. 5A and 5B show the device in its closed position in which the slider 108 is held in place by a number of elements 116 and 118 that mate with pockets (e.g., pin pockets) 124. The location of elements 116 extend through the housing at the positions indicated while the device 100 is in the closed position. A single nozzle 122 is shown in the view of FIG. 5A and two nozzles are shown in the view of FIG. 5B. One or more top housing seals (e.g., sealing O-rings) 126 assist in containing the dispensable substance behind the slider 108 so that the dispensable substance does not leak to the environment external to the device 100. A piston (e.g., substance/gas piston) 130 and a seal (e.g., sealing O-ring) 132 assist in separating the gas in the gas reservoir 112 from the dispensable substance in the substance reservoir 114. The piston 130 surrounds the gas reservoir 112 and is configured to slide axially within the bottom housing 104. In some embodiments, the slider 108 is not an external sliding mechanism as shown, but is an internal slider.

With the dispensable substance loaded within the substance reservoir 114, the slider 108 is held in place with respect to the top housing 134 with the elements 116 and structural elements 118 within the pockets 124. The pockets 124 each have a through-portion 124A piercing the slider 108, and a blind hole potion 124B within the top housing 134. In the closed position (FIGS. 5A and 5B), the through-portion 124A and the blind hole portion 124B of each of the pockets 124 align, allowing the elements 116 and/or 118 to be inserted through the slider 108 and fasten it to the top housing 134. Once in this fixed position, the gas reservoir 112 is charged with pressurized gas up to a predetermined pressure (e.g., about 300 psig) via the inlet 106. The inlet 106 includes a valve 128 that allows gas to flow into the gas reservoir 112, but prevents the pressurized gas from travelling back out through the inlet 106. In general, any appropriate valve may be used. Examples of valves include check valves, ball check valves, umbrella valves, duckbill valves, or the like. In some embodiments, the valve 128 is replaced by a static plug (e.g., an adhesive applied to the inlet 106) that can withstand the pressure of the pressurized gas reservoir 112.

The elements 116 and 118 are generally made of materials and are sized and shaped such that they, in combination, provide enough rigidity to hold the slider 108 in the closed position under the internal pressure of the pressurized air in the gas reservoir 112, e.g., in the range of about 150-400 psig. Upon dissolution, degradation and or erosion of the elements 116, the maximum pressure that the remaining structural elements 118 can withstand without breaking drops below the internal pressure within the gas reservoir 112. In some embodiments, the structural elements 118 are made from a relatively brittle material, and thereby fail and release the slider 108 and allow the dispensable substance to forcefully leave the device via the nozzles 122. Although FIGS. 4A-5B show a single element 116 and a single element 118, the disclosure is not limited in this sense. For example, the device 100 can include more than one (e.g., two, three, four, etc.) elements 116, and/or more than one (e.g., two, three, four, etc.) elements 118. In some embodiments, there is an even number of elements 116 and of structural elements 118, and the elements 116 and 118 are arranged in an alternating configuration around the longitudinal axis of the device 100. In other embodiments, there is an even number of elements 116 and of structural elements 118, and the elements 116 and 118 are arranged such that elements 116 are opposite other elements 116 and structural elements 118 are opposite other structural elements 118 around the longitudinal axis of the device 100. In certain embodiments, elements 116 and 118 are co-located within the same pocket 124 and may comprise a matrix of materials such as 118 consisting of fibers, or consisting of a coaxial pin 118 surrounded by an annulus of element 116. In some embodiments, the coating 120 may be placed only in the region of the elements 116 and/or 118, e.g., in an annulus. Alternatively, enteric material may be in the pocket portions 124A and/or 124B as a plug separating the elements 116 and/or 118 from the exterior environment.

The properties of the elements 116 can be varied to select the desired performance. For example, their effective force-restraining area can be increased by increasing the diameter and thus the cross section of each element 116, and/or by increasing the number of the elements 116. Increasing the area allows for a safety factor to permit longer periods of storage and shipping, variation in dissolvability, degradability and or erodability between batches of elements 116 and/or 118, and variations in the pressure within the gas reservoir 112, or the like. In some embodiments, elements 116 and 118 are pins having a diameter of about 0.9 mm, but can be thinner (e.g., about 0.8 mm) or wider.

In some embodiments, the elements 116 and/or the structural elements 118 have configurations other than straight pins. For example, one or more elements 116 can be an annular member that fits within a grooved pocket (rather than the discrete pockets 124 shown) that encircles the circumference of the slider 108. The element(s) can be cotters, shear pins, linchpins, split pins, straight pins, dowels, biscuits, clasps, clamps, flanges, rivets, or the like. In some embodiments one or more of the elements 116 is a restraining device other than a pin, such as a clamp, a spacer, or the like.

The gas reservoir 112 contains pressurized gas. In some embodiments, the gas is air, however gases other than air are possible. Nonlimiting examples of compressed gases include, nitrogen (N₂), oxygen (O₂), argon (Ar), krypton (Kr), helium (He) or other inert or noble gases that do not interact or are compatible with the GI tract, with preference to higher molecular weight gasses that would decrease any permeation of the drive gas out of the device and therefore increase shelf life. In some embodiments, the gas is carbon dioxide (CO₂).

The device 100 maintains a gas/fluid barrier internally, and the gas reservoir 112 can keep pressurized gas from interacting with a fluid dispensable substance (e.g., dispensable substance in the substance reservoir 114). The substance reservoir 114 may have a residual volume of <0.050 mL after the dispensing period is complete, and does not induce agglomeration that would prevent therapeutic agent delivery.

The device 100 also can have several characteristics that make it safe to be stored and transported before being swallowed by a patient. The device 100 can maintain an internal pressure of about 350 psig over the shelf life of the device, e.g., hold a pressure of about 350 psig for about 6 months. The dispensable substance-contacting substance reservoir 114 does not have an effect on the therapeutic agent contained within, and the device and the therapeutic agent are not affected (in efficacy, safety, consistency, or bioavailability) by each other during device storage, transit, and dispensing (e.g., with a storage time up to about six months, or up to about 12 months). The substance reservoir 114 can resist contamination from outside sources prior to dispensing.

In some embodiments, as shown in FIG. 6, the diameter of a nozzle as measured at the point of interface with the dispensable substance reservoir can be the same as, smaller than, or larger than the diameter as measured at the nozzle opening (location of delivery of the dispensable substance from the ingestible device). Table 1 provides nozzle diameter (in millimeters) and nozzle length (in millimeters) for the nozzle designs shown in FIG. 6.

In some embodiments, a tapered nozzle may exhibit enhanced jetting properties. In certain embodiments, a non-tapered nozzle relatively may be relatively inexpensive and simple to manufacture. In some embodiments, a small reducing in certain jet properties with a relatively simplified (e.g., non-tapered) nozzle can be compensated with variation of more easily controlled parameters such as the internal pressure and/or fluid pressure. In some embodiments where the jet exhibits turbulent flow, considering the variations in the flow profile which is inherent to the turbulent nature of the flow, and small impacts of nozzle length variations on the jet velocity, the length of the nozzle may be selected based on mechanical design constraints and required thickness of the ingestible devices.

In some embodiments, a smaller nozzle diameter (e.g., about 0.35 millimeter) is can result in longer dispensing time (˜120 milliseconds), which can better align with achievable opening times of ˜10 milliseconds and higher velocity for a given peak internal pressure. In some embodiments, a smaller nozzle diameter can also provide actual dispensing times and jet velocities that are closer to the predicted values.

FIG. 6 shows exemplary cross sections of the nozzles 122 within the slider 108 (although nozzles depicted in FIG. 6 may be used in one or more of other embodiments of ingestible devices disclosed herein). In some embodiments, the nozzles are about 0.15-0.5 mm in diameter and about 0.3-1.5 mm in length. The throat (e.g., the narrowing portion) of the nozzle can be rounded (as in the top right) or sharp (as in the bottom left) and the neck can have varying lengths. Each of these parameters have an effect on the jet(s) generated by the nozzle, modulating, for example, average jet diameter, jet velocity, peak jet power, peak jet pressure, peak jet force, and average dispensing time. These characteristics can affect the efficacy of delivery and/or subject uptake of the therapeutic agent.

FIG. 7 shows a histologic example of a jetted fluid in situ. This result was achieved with a 0.35 mm nozzle and jetting pressure of 250 psig, and an estimated 181 μL bolus volume. The fluid passed through the mucosa and is within the submucosal region. In this example, the complete bolus was not delivered, possibly due to the physical volume constraints of the region. This indicates that multiple nozzles each delivering a smaller bolus of therapeutic agent may be preferred to maximize the bioavailability of the therapeutic agent.

Referring back to FIGS. 4A-5B, the ingestible device 100 has a triggering mechanism that causes the device 100 to release the dispensable substance within the substance reservoir 114 when the ingestible device reaches the desired location within the GI tract. The trigger that initiates dispensable substance release can have two parts: the enteric coating 120 enrobing the exterior surface 102 of the device 100, and the elements 116. The elements 116 are either covered with an enteric coating or are themselves are made of an enteric material. The enteric material may be degradable and/or erodible in the small intestine of the GI tract, or may be degradable and/or erodible in the large intestine of the GI tract, for example, the colon. Such a two-stage release mechanism allows the device 100 to transit through the GI tract to the desired location intact before releasing the therapeutic agent.

In the first stage, the enteric coating 120 dissolves, degrades and/or erodes while the device 100 is within a desired portion of the GI tract, e.g., the small intestine or the large intestine. The enteric coating 120 is chosen such that it is stable in the acidic environment of the stomach and dissolves, degrades and/or erods only when exposed to the more neutral environment of the small intestines (e.g., pH >5) or the slightly acidic to neutral environment of the large intestine (e.g., pH 5.5-7). The thickness of the coating 120 is chosen such that it dissolves, degrades and/or erodes (either entirely, or enough to expose the elements 116) when the swallowed device 100 is predicted to have transited through the stomach and be within the small intestine or large intestine.

Once the enteric coating 120 has dissolved, degraded and/or eroded from the exterior surface 102 of the device 100, the elements 116 of the device 100 are exposed to the GI tract. The elements 116 are configured to dissolve, degrade and/or erod upon exposure to the environment of the small intestine (e.g., a water soluble material). Generally, the elements 116 dissolve, degrade and/or erode more rapidly than does the enteric coating 120. The elements 116 can dissolve, for example, within about 1 minute of the enteric coating 120 dissolving, degrading and/or eroding and exposing the elements 116 to the small intestine environment, compared to, for example, about 30 minutes for the enteric coating 120 to degrade. It is not necessary that the enteric coating 120 dissolves, degrades and/or erodes in its entirety. As the enteric coating 120 starts to degrade water or other luminal contents may pass through it and cause the elements 116 to dissolve and thereby lose their mechanical holding strength.

Materials for the elements 116 can be isomalt, sugars like maltose or sucrose, or degrading materials of different sorts.

The elements 116 and the structural elements 118 can be made of materials and are sized and shaped such that they, in combination, provide enough rigidity to hold the slider 108 in the closed position under the pressure of the pressurized gas in the gas reservoir 112, which can be in the range of 150-400 psig. For example, if the gas reservoir 112 is to be pressurized to 260 psig, the elements 116 and the structural elements 118 can be designed to hold back 300 psig of pressure. In one arrangement, the retaining strength of the elements 116 is 80 psig, and the retaining strength of the structural elements 118 is 220 psig. Upon dissolution, degradation and/or erosion of the elements 116, the structural elements 118 are exposed to the pressure of 260 psig within the gas reservoir 112. As the 260 psig within the gas reservoir 112 exceeds the reduced restraining strength of 220 psig, the remaining structural elements 118 break. The combination of the dissolution, degradation and/or erosion of the elements 116 followed by the breaking of the structural elements 118 releases the slider 108.

In some embodiments, the elements 116 and the structural elements 118 are made of the same material. The elements 116 have a smaller cross sectional area than the structural elements 118 and thus fail more quickly than the structural elements 118. In other embodiments, the elements 116 and the structural elements 118 are made of different materials, where the structural elements 118 are stronger but more brittle than the elements 116.

In some embodiments, only elements 116 are present, without structural elements 118. In such instances, the elements 116 are configured to break and release the piston 130 and slider 108 in a single step (following dissolving, degrading and/or eroding of the enteric coating 120).

To dispense the therapeutic agent, the device 100 moves from the closed position in FIGS. 5A and 5B back to the open position of FIGS. 3B and 3C where the substance reservoir 114 is fluidly connected to the outside of the device (in this instance, with the GI tract). Once the shear pins dissolve/degrade/erode and/or are sheared, the piston 130 is released to slide axially within the bottom housing 104, and the slider 108 slides relative to the top housing 134. The motion of the slider 108 positions the nozzles 122 such that the portion of the nozzles 122 within the top housing 134 aligns with the fluid outlet portion of the nozzles 122 within the slider 108. The movement of the piston 130, driven by the now-unrestrained pressure within the air reservoir 122, forces the therapeutic within the substance reservoir 114 out through the nozzles 122. The elements 116 and 118 may remain only in the blind hole portion 124B of the pockets 124. In some embodiments, the dispensing time is approximately 120 ms. In some embodiments, the time for the slider 108 to move from the closed to the open position is approximately 10 ms.

FIG. 8 shows an exemplary process flow chart 800 for use of an ingestible device in which pressure is applied to the dispensable substance before the subject swallows the ingestible device. The process begins at step 802, when the patient swallows the ingestible device. In step 804, a triggering condition (e.g., pH, change in pH, presence of certain enzyme, concentration of certain enzyme) is met in the GI tract, thereby triggering the release mechanism. In step 806, the release mechanism actuates the delivery mechanism at the intended location of the GI tract, whereby the opening(s) of the ingestible device become open. In step 808, force applied to the dispensable substance by the drive mechanism generates high-speed flow of the dispensable substance through the opening(s) in the ingestible device, resulting in delivery of a jet of the dispensable substance from the ingestible device for each opening. In step 810, the jet has a sufficient jet stable length for the jet to impact the GI tissue of the subject. In step 812, the peak jet power of the jet is sufficient to achieve trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In step 814, the fluid pressure of the dispensable substance decreases during delivery but is sufficiently so that the peak jet power continues to be sufficient to achieve trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 9A shows an embodiment of an ingestible device 900 for trans-epithelial delivery. The device 900 includes housing parts 902A and 902B, a fluid volume 904 containing a dispensable substance, nozzles 906 with nozzle openings 908, pressurized gas as a drive force generator 910, a drive coupling 912 with an O-ring 913 seal, a ring 914 and a valve 915 (inlet for compressed gas). Similar to the device shown in FIGS. 4A-5B, when the device 900 is swallowed by the subject, the dispensable substance in the device is already pressurized. However, the ring 914 prevents the pressure of the drive force generator 910 and the drive coupling 912 from forcing the dispensable substance in the fluid volume 904 through the nozzle openings 908. When the device 900 reaches the appropriate location in the GI tract, the ring 914 erodes, degrades and/or dissolves. Thus, the pressure of the drive force generator 910 and the drive coupling 912 is applied to the dispensable substance 904, forcing the cap to move to expose openings 908. As shown in FIG. 9B, the housing part 902B has a slot 903 into which a portion of housing part 902A fits such that the motion of the housing part 902A is both axial and rotational (e.g., a track and cam arrangement). This arrangement can result in relatively reduced axial movement of the housing part 902B during delivery of the dispensable substance, which can result in maintenance of a relatively high internal pressure during delivery of the dispensable substance.

FIG. 10A shows an embodiment of an ingestible device 1000 for trans-epithelial delivery. FIG. 10B is an exploded view of the ingestible device 1000. The ingestible device 1000 has housing parts 1002A and 1002B, a fluid volume 1004 containing a dispensable substance, nozzles 1006, nozzle openings 1008, parallel springs 1010A and 1010B, a piston 1012, a pin 1014, a pin 1016, a spring 1018 and a cap 1020. Similar to the device shown in FIGS. 4A-5B, when the device 1000 is swallowed by the subject, the dispensable substance in the device is already pressurized. However, the pins 1014 and 1016 prevent the pressure of the springs 1010A and 1010B and the piston 1012 from forcing the dispensable substance in the fluid volume 1004 through the nozzle openings 1008. When the device 1000 reaches the appropriate location in the GI tract, the pin 1014 erodes, degrades and/or dissolves, and the pin 1016 is not sufficient to hold back the pressure from the springs 1010A and 1010B and the piston 1012. Thus, the pressure of the springs 1010A an 1010B and the piston 1012 is applied to the dispensable substance, forcing the spring 1020 to quickly move the cap 1018 forward. This rapidly exposes the nozzle openings 1008 to the environment exterior to the device 1000 so that the dispensable substance is delivered out of the openings 1008 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 1000 has a diameter of about 11 mm, a length of about 26 mm, a wall thickness of about 0.8 mm, an end round of about 1.5 mm and an internal volume of about 1685 μL. In such embodiments, the fluid volume 1004 can be about 325 L.

FIG. 10C shows aspects of steps in assembling the ingestible device 1000. In step 1020, the cap 1020 and spring 1018 are combined with the housing part 1002B and pins 1014 and 1016, and this module is sterilized. In step 1022, the dispensable substance 1004 is disposed in the housing part 1002B in an aseptic environment and then sealed within the housing part 1002B via the piston 1012. In step 1024, the housing part 1002A and its components are assembled in a clean environment. In step 1026, the resulting modules are joined together in a clean environment to compress the springs 1O10A and 1010B to provide the ingestible device 1000. As shown in step 1026, the assembly process can include using a jig to hold the housing part 1002A to prevent over-loading of the cap 1020/spring 1018/pin 1014/pin 1016 combination.

FIG. 10D shows an embodiment of an ingestible device 10001 for trans-epithelial delivery. The ingestible device 10001 has housing parts 1002A1 and 1002B1, a fluid volume 10041 containing a dispensable substance, nozzles 10061, nozzle openings 10081, parallel springs 1010A1 and 1010B1, a piston 10121, a pin 10141, a pin 10161, a spring 10181 and a cap 10201. Similar to the device shown in FIGS. 4A-5B, when the device 10001 is swallowed by the subject, the dispensable substance in the device is already pressurized. However, the pins 10141 and 10161 prevent the pressure of the springs 1010A1 and 1010B1 and the piston 10121 from forcing the dispensable substance in the fluid volume 10041 through the nozzle openings 10081. When the device 10001 reaches the appropriate location in the GI tract, the pin 10141 erodes, degrades and/or dissolves, and the pin 10161 is not sufficient to hold back the pressure from the springs 1010A1 and 1010B1 and the piston 10121. Thus, the pressure of the springs 1O10A1 an 1010B1 and the piston 10121 is applied to the dispensable substance, forcing the spring 10201 to quickly remove move the cap 10181 forward. This rapidly exposes the nozzle openings 10081 to the environment exterior to the device 10001 so that the dispensable substance is delivered out of the openings 10081 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the spring force of the spring 10181 has a force of about 30 Newtons, the parallel springs 1010A1 and 1010B1 have a force of 110 Newtons to provide an internal pressure of about 320 psig with about 50 Newtons of force at the end of the stroke, and the fluid volume 10041 is about 225 μL. In some embodiments, the housing of the ingestible device 10001 has a diameter of about 11 mm, a length of about 26 mm, a wall thickness of about 0.8 mm, an end round of about 5.5 mm (spherical) and an internal volume of about 1475 μL. In such embodiments, the fluid volume 10041 can be about 225 μL.

FIG. 10E shows an embodiment of an ingestible device 10002 for trans-epithelial delivery. The ingestible device 10002 has housing parts 1002A2 and 1002B2, a fluid volume 10042 containing a dispensable substance, nozzles 10062, nozzle openings 10082, parallel springs 1010A2 and 1010B2, a piston 10122, a pin 10142, a pin 10162, a spring 10182 and a cap 10202. Similar to the device shown in FIGS. 4A-5B, when the device 10002 is swallowed by the subject, the dispensable substance in the device is already pressurized. However, the pins 10142 and 10162 prevent the pressure of the springs 1010A2 and 1010B2 and the piston 10122 from forcing the dispensable substance in the fluid volume 10042 through the nozzle openings 10082. When the device 10002 reaches the appropriate location in the GI tract, the pin 10142 erodes, degrades and/or dissolves, and the pin 10162 is not sufficient to hold back the pressure from the springs 1010A2 and 1010B2 and the piston 10122. Thus, the pressure of the springs 1010A2 an 1010B2 and the piston 10122 is applied to the dispensable substance, forcing the spring 10202 to quickly remove move the cap 10182 forward. This rapidly exposes the nozzle openings 10082 to the environment exterior to the device 10002 so that the dispensable substance is delivered out of the openings 10082 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the spring force of the spring 10182 has a force of about 12 Newtons, the parallel springs 1010A2 and 1010B2 have a force of 58 Newtons to provide an internal pressure of about 320 psig with about 25 Newtons of force at the end of the stroke, and the fluid volume 10042 is about 120 μL. In some embodiments, the housing of the ingestible device 10002 has a diameter of about 8.5 mm, a length of about 23.3 mm, a wall thickness of about 0.75 mm, an end round of about 4.25 mm (spherical) and an internal volume of about 775 μL. In such embodiments, the fluid volume 10042 can be about 120 μL.

FIG. 11 shows an ingestible device 1100 which includes a housing 1102, a fluid volume 1104, a liquid-gas reservoir (drive force generator) 1106, a drive coupling 1108, a seal 1109, a pin 1114 and a pin 1116. The ingestible device 1100 is configured so that, before the subject swallows the device, the dispensable substance in fluid volume 1104 is under pressure from the liquid-gas reservoir 1106 via the drive coupling 1108, but the pins 1114 and 1116 prevent the dispensable substance in fluid volume 1004 from being delivered from the device 1100 via nozzle(s) with nozzle opening(s) (not shown). When the device 1100 reaches the appropriate location in the GI tract, the pin 1114 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 1116 is no longer sufficient to hold back the pressure from the liquid-gas reservoir 1106 and the drive coupling 1108. Thus, this pressure is applied to the dispensable substance in the fluid volume 1104, forcing the dispensable substance out of the nozzle openings (not shown) in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 12 shows an ingestible device 1200 which includes a first housing part 1202A, a second housing part 1202B, a fluid volume 1204, a drive force generator 1206, nozzles 1208 with nozzle openings 1210, plugs 1212, a seal 1214, a seal 1216 and a membrane 1218. The ingestible device 1200 is configured so that, before the subject swallows the device, the dispensable substance in fluid volume 1204 is under pressure from the drive force generator 1206, but the plugs 1212 prevent the dispensable substance in fluid volume 1204 from being delivered from the device 1200 via nozzle openings 1210. When the device 1200 reaches the appropriate location in the GI tract, the plugs 1212 erode, degrade and/or dissolve (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), so that the pressure from the drive force generator 1206 breaks the seal 1216 (made of a relatively low mechanical strength material, such as a seal), which causes the membrane 1218 to expand into the fluid volume 1204, forcing the dispensable substance out of the nozzle openings 1210 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

The housing parts 1202A and (including the membrane 1218) are initially separate from each other. The plugs are disposed in the nozzles 1210, the dispensable substance is disposed in the fluid volume 1204, and the seal 1216 is added. The dispensable substance (including the therapeutic agent) is first sterilized, and then disposed in the fluid volume 1204 under aseptic conditions. The drive force generator 1206 is manufactured in a clean environment and then incorporated with the housing part 1202B, after which the membrane 1218 is added. Subsequently, the housing parts 1202A and 1202B are joined in a clean environment to produce the ingestible device 1200.

FIG. 13 shows an embodiment of an ingestible device 1300 for trans-epithelial delivery. The device 1300 has a housing 1302 with a fluid volume 1304 containing a dispensable substance, nozzles 1306, nozzle openings 1308, a tensioned spring 1310, a drive force generator 1312, a band 1314 around the device, a seal 1315, a cap 1318, a membrane 1317 and a seal 1320. When the device 1300 is swallowed by the subject, the dispensable substance in the device is already pressurized. However, the band 1314 prevents the pressure of the drive force generator 1312 from relieving the tension in the spring 1310 so that the dispensable substance in the fluid volume 1304 is prevented from going through the nozzle openings 1308. When the device 1300 reaches the appropriate location in the GI tract, the band 1314 erodes, degrades and/or dissolves. Thus, the tension in the spring 1310 is relieved, and the spring moves to where the band 1314 was located, thereby rapidly exposing the nozzle openings 1308 to the environment exterior to the device 1300 so that the dispensable substance is delivered out of the openings 1308 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 14 shows an embodiment of an ingestible device 1400 for trans-epithelial delivery. The device 1400 has a housing 1402 with a fluid volume 1404 containing a dispensable substance, a membrane 1405 defining the fluid volume 1404, an opening 1407 leading to nozzles 1406, nozzle openings 1408, a tensioned spring 1410, a pressurized gas (drive force generator) 1412, a band 1414, a cap 1418 and a seal 1420. When the device 1400 is swallowed by the subject, the dispensable substance in the device is already pressurized. However, the band 1414 keeps the spring 1410 tensioned so that the dispensable substance in the fluid volume 1404 is prevented from going through the nozzle openings 1408. When the device 1400 reaches the appropriate location in the GI tract, the band 1414 erodes, degrades and/or dissolves, relieving the tension in the spring 1410, which moves to where the band 1414 had been located, thereby rapidly exposing the nozzle openings 1408 to the environment exterior to the device 1400 so that the dispensable substance is delivered out of the openings 1408 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

In some embodiments, the dispensable substance is not under pressure when the subject swallows the ingestible device. The following are illustrative examples of such ingestible devices.

As an example, FIG. 15A shows an embodiment of an ingestible device 1500 for trans-epithelial delivery. FIG. 15B shows an exploded view of the ingestible device 1500. The ingestible device 1500 has housing parts 1502A and 1502B, a fluid volume 1504 containing a dispensable substance, nozzles 1506, nozzle openings 1508, parallel springs 1510A and 1510B, a plunger 1511, a piston 1512, a piston 1513, a pin 1514 and a pin 1516. When the device 1500 is swallowed by the subject, the pins 1514 and 1516 prevent the dispensable substance in fluid volume 1504 from being under pressure from the springs 1510A and 1510B, the plunger 1511 and the piston 1512. Thus, the pins 1514 and 1516 prevent the pressure of the springs 1510A and 1510B, the plunger 1511 and the piston 1512 from forcing the dispensable substance in the fluid volume 1504 through the openings 1508. When the device 1500 reaches the appropriate location in the GI tract, the pin 1514 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 1516 is no longer sufficient to hold back the pressure from the springs 1510A and 1510B, the plunger 1511 and the piston 1512. Thus, the pressure of the springs 1510A and 1510B, the plunger 1511 and the piston 1512 is applied to the dispensable substance in the fluid volume 1504, forcing the dispensable substance out of the nozzle openings 1508 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 15C shows aspects of a process of assembling the ingestible device of 1500. In steps 1520 and 1522, the housing part 1502B and piston 1513 are combined and sterilized, the dispensable substance 1504 is added to the housing part 1502B in an aseptic environment, and drive piston 1511 is added to the housing part 1502B to seal the dispensable substance 1504 in the housing part 1502B. In step 1524, the housing part 1502A and its components are assembled in a clean environment. The drive plunger 1512 is used to compress the springs 1510A and 1510B, and the drive plunger 1512 is held in place via the pins 1514 and 1516. In step 1526, the resulting modules are assembled in a clean environment to produce the ingestible device 1500.

FIG. 16 shows an exemplary process flow chart 1600 for use of an ingestible device in which pressure is not applied to the dispensable substance before the subject swallows the ingestible device. The process beings at step 1602, when the patient swallows the ingestible device. In step 1604, a triggering condition (e.g., pH, change in pH, presence of certain enzyme, concentration of certain enzyme) is met in the GI tract, thereby triggering the drive force generator. In step 1606, the drive force mechanism applies pressure to the dispensable substance, resulting delivery of a jet of the dispensable substance from the ingestible device for each opening. In step 1608, the jet has a sufficient jet stable length for the jet to impact the GI tissue of the subject. In step 1610, the peak jet power of the jet is sufficient to achieve trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In step 1612, the fluid pressure of the dispensable substance decreases during delivery but is sufficiently so that the peak jet power continues to be sufficient to achieve trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 17 shows an embodiment of an ingestible device 1700 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The device 1700 has a housing 1702 with a fluid volume 1704 containing a dispensable substance, nozzles 1706, nozzle openings 1708, coverings 1709 over openings 1708, a spring 1710, a piston 1712, a fluid barrier 1713 (to prevent the dispensable substance from contacting the piston 1712 or the spring 1710), a pin 1714 and a pin 1716. When the device 1700 is swallowed by the subject, the pins 1714 and 1716 prevent the dispensable substance in fluid volume 1704 from being under pressure from the spring 1710 and the piston 1712, and the coverings 1709 prevent the dispensable substance from exiting the device via openings 1708. When the device 1700 reaches the appropriate location in the GI tract, the pin 1714 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 1716 is no longer sufficient to hold back the pressure from the spring 1710 and the piston 1712. Thus, the pressure of the spring 1710 and the piston 1712 is applied to the dispensable substance in the fluid volume 1704, forcing the seals 1709, which are made of a relatively low mechanical strength material (e.g., a foil or a film) to break so that the dispensable substance is delivered out of the nozzle openings 1708 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 18 shows an embodiment of an ingestible device 1800 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The device 1800 has a housing 1802 with a fluid volume 1804 containing a dispensable substance, nozzles 1806, nozzle openings 1808, coverings 1809 over openings 1808, a spring 1810, a piston 1812, a pin 1814 and a pin 1816. When the device 1800 is swallowed by the subject, the pins 1814 and 1816 prevent the dispensable substance in fluid volume 1804 from being under pressure from the spring 1810 and the piston 1812, and the coverings 1809 prevent the dispensable substance from exiting the device via openings 1808. When the device 1800 reaches the appropriate location in the GI tract, the pin 1814 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 1816 is no longer sufficient to hold back the pressure from the spring 1810 and the piston 1812. Thus, the pressure of the spring 1810 and the piston 1812 is applied to the dispensable substance in the fluid volume 1804, forcing the seals 1809, which are made of a relatively low mechanical strength material (e.g., a foil or a film) to break so that the dispensable substance is delivered out of the nozzle openings 1808 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 19A shows an embodiment of an ingestible device 1900 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. FIG. 19B is an exploded view of the ingestible device 1900. The ingestible device 1900 has a cap 1901, housing parts 1902A and 1902B with a fluid volume 1904 containing a dispensable substance, nozzles 1906, nozzle openings 1908, coverings 1909 over openings 1908, a seal 1913, a spring 1910, a gas cylinder 1911, a membrane 1915 surrounding the gas cylinder 1911, a piercer 1912, a pin 1914, a pin 1916, and an O-ring 1919. The cap 1901 is removed before the subject swallows the ingestible device 1900. When the device 1900 is swallowed by the subject, the pins 1914 and 1916 prevent the dispensable substance in fluid volume 1904 from being under pressure by holding the spring 1910 and the piercer 1912 in place. When the device 1900 reaches the appropriate location in the GI tract, the pin 1914 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 1916 is no longer sufficient to hold back the pressure from the spring 1910. The spring forces the piercer 1912 into the gas cylinder 1911, puncturing the gas cylinder 1911 and causing gas at elevated pressure to leave the cylinder 1911. This causes the cylinder to press against the membrane 1915, which expands against the seal 1913. The seal 1913 is made of a relatively low mechanical strength material (e.g., a foil or a film), which breaks when pressed against by the expanding membrane 1915. This causes the expanding membrane 1915 to apply pressure against the dispensable substance in the fluid volume 1904. This causes the coverings 1909, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 1908 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 1900 is about 26 millimeters long, has a diameter of about 11 mm, a wall thickness of about 0.8 mm Newtons, an end round of about 1.5 mm, an internal volume of about 1685 μL. In such embodiments, the fluid volume 1904 can be about 425 μL. In some embodiments, the ingestible device 1900 does not include coverings 1909.

FIG. 19C schematically shows certain aspects of a process for the assembly of the ingestible device 1900. In step 1920, the housing part 1902 is combined with the cap 1901 and coverings 1909. In step 1922, the dispensable substance 1904 is added to the housing part 1902B in an aseptic environment, and the seal 1913 is added. In step 1924, the housing part 1902A and its components are assembled in a clean environment. The piercer 1912 is held in place by pins 1914 and 1916, and the gas cylinder 1911 is held in place by components of this assembly. In step 1926, the resulting modules are combined to provide the ingestible device 1900.

FIG. 19D shows an ingestible device 19001 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 19001 has housing parts 1902A1 and 1902B1 with a fluid volume 19041 containing a dispensable substance, nozzles 19061, nozzle openings 19081, coverings 19091 over openings 19081, a spring 19101, a gas cylinder 19111, a piston 19151, a piercer 19121, and an O-ring 19191. The pins used as the triggering mechanism are not shown in FIG. 19D but are similarly configured as pins 1914 and 1916 in FIG. 19A. When the device 19001 is swallowed by the subject, the pins prevent the dispensable substance in fluid volume 19041 from being under pressure by holding the spring 19101 and the piercer 19121 in place. When the device 19001 reaches the appropriate location in the GI tract, one of the pins erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the other pin is no longer sufficient to hold back the pressure from the spring 19101. The spring forces the piercer 19121 into the gas cylinder 19111, puncturing the gas cylinder 19111 and causing gas at elevated pressure to leave the cylinder 19111. This causes the gas cylinder 19111 to press against the piston 19151 and apply pressure to the fluid volume 19041. This causes the coverings 19091, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 19081 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 19001 has a diameter of about 11 mm, a length of about 26 mm, a wall thickness of about 0.8 mm, an end round of about 5.5 mm (spherical), and an internal volume of about 1475 μL. In such embodiments, a fluid volume 19041 can be about 400 μL, and a gas volume in the gas cylinder 19111 can be about 255 μL.

FIG. 19E shows an ingestible device 19002 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 19002 has housing parts 1902A2 and 1902B2 with a fluid volume 19042 containing a dispensable substance, nozzles 19062, nozzle openings 19082, coverings 19092 over openings 19082, a spring 19102, a gas cylinder 19112, a piston 19152, a piercer 19122, and an O-ring 19192. The pins used as the triggering mechanism are not shown in FIG. 19E but are similarly configured as pins 1914 and 1916 in FIG. 19A. When the device 19002 is swallowed by the subject, the pins prevent the dispensable substance in fluid volume 19042 from being under pressure by holding the spring 19102 and the piercer 19122 in place. When the device 19002 reaches the appropriate location in the GI tract, one of the pins erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the other pin is no longer sufficient to hold back the pressure from the spring 19102. The spring forces the piercer 19122 into the gas cylinder 19112, puncturing the gas cylinder 19112 and causing gas at elevated pressure to leave the cylinder 19112. This causes the gas cylinder 19112 to press against the piston 19152 and apply pressure to the fluid volume 19042. This causes the coverings 19092, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 19082 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 19002 has a diameter of about 9.9 mm, a length of about 26.1 mm, a wall thickness of about 0.7 mm, a fluid volume 19042 of about 445 μL, a gas volume in the gas cylinder 19112 of about 193 μL.

FIG. 19F shows an ingestible device 19003 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 19003 has housing parts 1902A3 and 1902B3 with a fluid volume 19043 containing a dispensable substance, nozzles 19063, nozzle openings 19083, coverings 19093 over openings 19083, a spring 19103, a gas cylinder 19113, a pin 19143, a pin 19163, a piston 19153, a piercer 19123, and an O-ring 19193. When the device 19003 is swallowed by the subject, the pins 19143 ad 19163 prevent the dispensable substance in fluid volume 19043 from being under pressure by holding the spring 191033 and the piercer 19123 in place. When the device 19003 reaches the appropriate location in the GI tract, the pin 19143 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 19163 is no longer sufficient to hold back the pressure from the spring 19103. The spring forces the piercer 19123 into the gas cylinder 19113, puncturing the gas cylinder 19113 and causing gas at elevated pressure to leave the cylinder 19113. This causes the gas cylinder 19113 to press against the piston 19153 and apply pressure to the fluid volume 19043. This causes the coverings 19093, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 19083 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 19003 has a diameter of about 8.5 mm, a length of about 23.3 mm, a wall thickness of about 0.7 mm, an end round of about 4.25 mm (spherical), and an internal volume of about 775 μL. In such embodiments, the fluid volume 19043 can be about 205 μL, and a gas volume in the gas cylinder 19113 can be about 160 μL.

FIG. 19G shows an ingestible device 19004 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 19004 has housing parts 1902A4 and 1902B4 with a fluid volume 19044 containing a dispensable substance, nozzles 19064, nozzle openings 19084, coverings 19094 over openings 19084, a spring 19104, a gas cylinder 19114, a pin 19144, a pin 19164, a gas cylinder 19114, a seal 19134, a membrane 19154, a piercer 19124, a pin 19144, and a pin 19164, and an O-ring 19194. When the device 19004 is swallowed by the subject, the pins 19144 and 19164 prevent the dispensable substance in fluid volume 19044 from being under pressure by holding the spring 19104 and the piercer 19124 in place. When the device 19004 reaches the appropriate location in the GI tract, the pin 19144 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 19164 is no longer sufficient to hold back the pressure from the spring 19104. The spring forces the piercer 19124 into the gas cylinder 19114, puncturing the gas cylinder 19114 and causing gas at elevated pressure to leave the cylinder 19114. This causes the cylinder to press against the membrane 19154, which expands against the seal 19134. The seal 19134 is made of a relatively low mechanical strength material (e.g., a foil or a film), which breaks when pressed against by the expanding membrane 19154. This causes the expanding membrane 19154 to apply pressure against the dispensable substance in the fluid volume 19044. This causes the coverings 19094, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 19084 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 19004 is about 26 millimeters long, has a diameter of about 11 mm, and a wall thickness of about 0.8 mm Newtons. In such embodiments, the fluid volume 19044 can be about 410 μL. In such embodiments, the gas volume of the gas cylinder 19114 can be about 216 μL, and the spring 19104 can provide a force of about 80 Newtons.

FIG. 19H shows an ingestible device 19005 for trans-epithelial delivery, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 19005 has housing parts 1902A5 and 1902B5 with a fluid volume 19045 containing a dispensable substance, nozzles 19065, nozzle openings 19085, coverings 19095 over openings 19085, a spring 19105, a gas cylinder 19115, a pin 19145, a pin 19165, a gas cylinder 19115, a membrane 19155, a piercer 19125, a pin 19145, and a pin 19165, and O-rings 19195. When the device 19005 is swallowed by the subject, the pins 19145 and 19165 prevent the dispensable substance in fluid volume 19045 from being under pressure by holding the spring 19105 and the piercer 19125 in place. When the device 19005 reaches the appropriate location in the GI tract, the pin 19145 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the pin 19165 is no longer sufficient to hold back the pressure from the spring 19105. The spring forces the piercer 19125 into the gas cylinder 19115, puncturing the gas cylinder 19115 and causing gas at elevated pressure to leave the cylinder 19115. This causes the cylinder to press against the membrane 19155, which causes the expanding membrane 19155 to apply pressure against the dispensable substance in the fluid volume 19045. This causes the coverings 19095, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 19085 in the form of a jet. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In some embodiments, the housing of the ingestible device 19005 is about 23.3 millimeters long, has a diameter of about 8.5 mm, and a wall thickness of about 0.7 mm. In such embodiments, the fluid volume 19045 can be about 300 μL. In such embodiments, the gas volume of the gas cylinder 19115 can be about 247 μL.

FIG. 19I shows a portion of an ingestible device including a housing part 19028, a gas cylinder 19118 with a membrane 19018, a piercer 19128 that is held in place via an enteric material 19148, and a biased diaphragm 19039. FIG. 19J shows corresponding portions of the ingestible device after the enteric material 19148 degrades/dissolves/erodes. The diaphragm 19038 has moved so that the piercer 19126 has pierced the membrane 19016, causing the gas in the gas cylinder 19116 to escape. Although not shown, the gas pressure causes another housing part (e.g., the housing part of the drug module) to move, to expose nozzle openings so that the dispensable substance leaves the ingestible device in the form jets for trans-epithelial delivery.

FIG. 19K shows a portion of an ingestible device including a housing part 19026, a gas cylinder 19116 with a membrane 19016, a piercer 19126 that is held in place via an enteric material 19146, stabilizing elements 19036A and 19036B, and a biasing element 19038 (e.g., a disc spring). FIG. 19K shows corresponding portions of the ingestible device after the enteric material 19146 degrades/dissolves/erodes. The spring biasing element 19038 has moved so that the piercer 19126 has pierced the membrane 19016, causing the gas in the gas cylinder 19116 to escape. Although not shown, the gas pressure causes another housing part (e.g., the housing part of the drug module) to move, to expose nozzle openings so that the dispensable substance leaves the ingestible device in the form jets for trans-epithelial delivery.

FIG. 20A shows an embodiment of an ingestible device 2000 for trans-epithelial delivery, containing a dispensable substance that is not under pressure when the subject swallows the ingestible device. The device 2000 has housing parts 2002A and 2002B with a fluid volume 2004 containing a dispensable substance, nozzles 2006, nozzle openings 2008, seals 2009 over openings 2008, a seal 2013, a gas cylinder 2011, a membrane 2015 between the seal 2013 and the gas cylinder 2011, a biased piercer 2012, and a plug 2013. When the device 2000 is swallowed by the subject, the plug 2013 keeps the piercer in its biased position as shown in FIG. 20A. When the device 2000 reaches the appropriate location in the GI tract, the plug 2013 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the piercer 2012 moves axially to pierce the gas cylinder 2011 and cause gas at elevated pressure to leave the cylinder 2011. This causes the cylinder to press against the membrane 2015, which breaks the seal 2013 so that the pressure is applied against the dispensable substance in the fluid volume 2004. This causes the coverings 2009, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings 2008 in the form of a jet. This results in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 20B schematically shows certain aspects of the assembly of the ingestible device 2000. The housing parts 2002A (including the seal 2013) and 2002B (including the membrane 2015, the gas cylinder 2011 and the piercer 2012) are initially separate from each other. The dispensable substance (including the therapeutic agent) is first sterilized, and then disposed in the fluid volume 2004 under aseptic conditions. The components in housing part 2002B are assembled in a clean environment. Subsequently, the housing parts 2002A and 2002B are joined in a clean environment to produce the ingestible device 2000.

FIG. 21A shows an embodiment of an ingestible device 2100 for trans-epithelial delivery, containing a dispensable substance that is not under pressure when the subject swallows the ingestible device. The device 2100 has housing parts 2102A and 2102B with a fluid volume 2104 containing a dispensable substance, nozzles 2106, nozzle openings 2108, a bellows 2110, a gas cylinder 2111, a biased piercer 2112, and a plug 2113. When the device 2100 is swallowed by the subject, the plug 2113 keeps the piercer in its biased position as shown in FIG. 20A. When the device 2100 reaches the appropriate location in the GI tract, the plug 2113 erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the piercer 2112 moves axially to pierce the gas cylinder 2111 and cause gas at elevated pressure to leave the cylinder 2111. This gas pressure is applied against press against the bellows 2110, causing the bellows 2110 such that holes in the bellows 21120 (not shown) align with the nozzles 2106 so that the dispensable substance is delivered out of the nozzle openings 2008 in the form of a jet. This results in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 21B schematically shows certain aspects of the assembly of the ingestible device 2100. The housing parts 2102A (including the bellows 2110) and 2102B (including the gas cylinder 2111 and the piercer 2112) are initially separate from each other. The dispensable substance (including the therapeutic agent) is first sterilized, and then disposed in the fluid volume 2104 under aseptic conditions. The components in housing part 2102B are assembled in a clean environment. Subsequently, the housing parts 2102A and 2102B are joined in a clean environment to produce the ingestible device 2100.

FIG. 23A shows an embodiment of an ingestible device 2300 for topical delivery. FIG. 23B is an exploded view of the ingestible device 2300. The ingestible device 2300 has housing parts 2302A and 2302B, a fluid volume 2304 containing a dispensable substance, an O-ring 2305, and a band 2306. The device 2300 has a head space pressure in the housing part 2302B, but the band 2306 holds the components of device 2300 in place when the device 2300 is swallowed by the subject. When the device 2300 reaches the appropriate location in the GI tract, the band 2306 erodes, degrades and/or dissolves, and the head space pressure causes the housing part 2302B to leave device 2300, resulting in the therapeutic agent in the dispensable substance being topically delivered to the GI tract of the subject. In embodiments having a design substantially similar to the ingestible device 2300, the head space pressure is provided by a gas, such as, for example, air nitrogen (N₂), oxygen (O₂), an inert gas (e.g., argon (Ar), krypton (Kr), helium (He)), and/or carbon dioxide (CO₂). In embodiments having a design substantially similar to the ingestible device 2300, the head space pressure can correspond to the internal pressure of the ingestible device. In embodiments having a design substantially similar to the ingestible device 2300, the head space pressure can correspond to the fluid pressure of the ingestible device.

FIG. 24 shows an embodiment of an ingestible device 2400 for topical delivery. The ingestible device 2400 has housing parts 2402A and 2402B, a fluid volume 2404 containing a dispensable substance, an O-ring 2405, and pins 2406 and 2408. The device 2400 has a head space pressure in the housing part 2402B, but the pins 2406 and 2408 hold the components of device 2400 in place when the device 2400 is swallowed by the subject. When the device 2400 reaches the appropriate location in the GI tract, the pins 2406 and 2408 erode, degrade and/or dissolve, and the head space pressure causes the housing part 2402B to leave device 2400, resulting in the therapeutic agent in the dispensable substance being topically delivered to the GI tract of the subject. In embodiments having a design substantially similar to the ingestible device 2400, the head space pressure is provided by a gas, such as, for example, air nitrogen (N₂), oxygen (O₂), an inert gas (e.g., argon (Ar), krypton (Kr), helium (He)), and/or carbon dioxide (CO₂). In embodiments having a design substantially similar to the ingestible device 2400, the head space pressure can correspond to the internal pressure of the ingestible device. In embodiments having a design substantially similar to the ingestible device 2400, the head space pressure can correspond to the fluid pressure of the ingestible device.

FIG. 25 shows an embodiment of an ingestible device 2500 for topical delivery. The ingestible device 2500 has housing parts 2502A and 2502B, a fluid volume 2504 containing a dispensable substance, and a partial coating 2506. The device 2500 has a head space pressure within the housing part 2502A, but the partial coating 2506 holds the components of device 2500 in place when the device 2500 is swallowed by the subject. When the device 2500 reaches the appropriate location in the GI tract, the partial coating 2506 erodes, degrades and/or dissolves, and the head space pressure causes the housing parts 2502A and 2502B to separate from each other, resulting in the therapeutic agent in the dispensable substance being topically delivered to the GI tract of the subject. In embodiments having a design substantially similar to the ingestible device 2500, the head space pressure is provided by a gas, such as, for example, air nitrogen (N₂), oxygen (O₂), an inert gas (e.g., argon (Ar), krypton (Kr), helium (He)), and/or carbon dioxide (CO₂). In embodiments having a design substantially similar to the ingestible device 2500, the head space pressure can correspond to the internal pressure of the ingestible device. In embodiments having a design substantially similar to the ingestible device 2500, the head space pressure can correspond to the fluid pressure of the ingestible device.

FIG. 26A shows an ingestible device 2600 that can be used for topical delivery. FIG. 26B is an exploded view of the device 2600. The device 2600 includes a first housing part 2602A, a second housing part 2602B and a third housing part 2602C. The device 2600 further includes a fluid volume 2604 containing a dispensable substance, a spring 2606, a plunger 2608, a piston 2610, an O-ring 2609, and a stopper pin 2612 which holds the components of the device 2600 when the subject swallows the device 2600. When the device 2600 reaches the appropriate location in the GI tract, the pin 2612 erodes, degrades and/or dissolves. Thus, the pressure of the spring 2606 is applied to the plunger 2608, which moves the piston 2610 axially. This pressure is transferred to the dispensable substance in the fluid volume 2604, which forces the housing part 2602C to be removed from the device 2600, and the therapeutic agent in the dispensable substance is topically delivered.

FIG. 26C shows aspects of steps in assembling the ingestible device 2600. In step 2620, the housing parts 2602B and 2602C are combined and then sterilized. In step 2622, the dispensable substance 2604 is disposed in the housing parts 2602B and 2602C in an aseptic environment and then sealed within the piston 2610. In step 2624, the housing part 2602A and its components are assembled in a clean environment. In step 2626, the resulting modules are joined together in a clean environment to provide the ingestible device 2600.

FIG. 27 shows an ingestible device 2700 that can be used for topical delivery. The device 2700 includes a first housing part 2702A and a second housing part 2702B. The device 2700 further includes a fluid volume 2704 containing a dispensable substance, a spring 2706, a seal 2708 (e.g., a foil or a film) and a partial coating 2710 which holds the components of the device 2700 when the subject swallows the device 2700. When the device 2700 reaches the appropriate location in the GI tract, the partial coating 2710 erodes, degrades and/or dissolves. The spring 2706 then exerts a pressure axially against the dispensable substance 2704, breaking the seal 2708 and also causing the housing parts 2702A and 2702B to separate, which results in topical delivery of the therapeutic agent in the dispensable substance.

FIG. 28A shows an ingestible device 2800 that can be used for topical delivery. The device 2800 includes a first housing part 2802A and a second housing part 2802B. The device 2800 further includes a fluid volume 2804 containing a dispensable substance, a spring 2806, a seal 2808, an O-ring 2809, and a partial coating 2810 which holds the components of the device 2800 when the subject swallows the device 2800. When the device 2800 reaches the appropriate location in the GI tract, the partial coating 2810 erodes, degrades and/or dissolves. As shown in FIG. 28B, this causes the spring 2806 to expand so that housing parts 2802A and 2802B separate, resulting in topical delivery of the therapeutic agent in the dispensable substance.

FIG. 29A shows an ingestible device 2900 for topical delivery. FIG. 29B is an exploded view of the device 2900. The device 2900 includes housing parts 2902A, 2902B and 2902C. The device also includes a fluid volume 2904 containing a dispensable substance, an O-ring 2906, a piston 2908 a gas cell 2910 (e.g., a hydrogen cell), a potting material 2911, an electrical contact 2912, and a plug 2914. The subject swallows the device 2900, and, when the device 2900 reaches an appropriate location in the GI tract of the subject, the plug 2914 erodes, degrades and/or dissolves. This causes the electrical contact 2912 to energize the gas cell 2910, which produces a pressurized gas (e.g., pressurized hydrogen) that pushes the piston 2908 axially. This movement applies a pressure to the fluid volume 2904, which transfers the pressure to the housing part 2902C. This causes the housing part 2902C to separate from the device 2900 so that the therapeutic agent in the dispensable substance is topically delivered.

FIG. 29C shows aspects of steps in assembling the ingestible device 2900. In step 2920, the housing parts 2902B and 2902C are combined and then sterilized. In step 2922, the dispensable substance 2904 is disposed in the housing parts 2902B and 2902C in an aseptic environment and then sealed within the piston 2908. In step 2924, the housing part 2902A and its components are assembled in a clean environment. In step 2926, the resulting modules are joined together in a clean environment to provide the ingestible device 2900.

FIG. 30 shows an ingestible device 3000 that can be used for topical delivery. The device 3000 includes housing parts 3002A, 3002B and 3002C. The device 2800 further includes a fluid volume 3004 containing a dispensable substance, a spring 3006, a plunger 3008 with piercing elements 3009, an O-Ring 3011, a sealed compartment 3010 containing separated reactants A and B, a piston 3010, and O-ring 3013, and a stopper pin 3012 which holds the components of the device 3000 when the subject swallows the device 3000. When the device 3000 reaches the appropriate location in the GI tract, the pin 3012 erodes, degrades and/or dissolves. This causes the spring 3006 to expand axially, moving the plunger 3008 axially so that the piercing elements 3009 puncture the sealed compartment 3010. This causes the reactants A and B to chemically react and form a pressurized gas which moves the piston axially, thereby applying a pressure against the fluid volume 3004. This pressure is transferred to the housing part 3002C, which forces the housing part 3002C to be removed from the device 3000, and the therapeutic agent in the dispensable substance is topically delivered.

FIG. 31A shows an ingestible device 3100 for topical delivery. The device 3100 includes housing parts 3102A and 3102B, a joint 3103, a pressurized fluid volume 3104 containing a dispensable substance, a membrane 3106 (e.g., balloon) containing the dispensable substance, a seal 3108 located in an opening 3103 of the housing part 3102B, and a plug 3110 in an opening 3112 of the housing part 3102A. The subject swallows the ingestible device 3100. When the device 3100 reaches the appropriate location in the GI tract, the plug 3110 erodes, degrades and/or dissolves. This causes the pressurized fluid 3104 in the membrane 3104 to leave the device 3100 via the opening 3112 so that the therapeutic agent in the dispensable substance is topically delivered.

FIG. 31B shows aspects of steps in assembling the ingestible device 3100. In step 3120, the plug 3112 is formed in the opening 3112 of the housing part 3102A, the membrane 3104 is put inside the housing part 3102A, and the dispensable substance is disposed in the membrane 3104 under aseptic conditions. In step 3122, the housing part 3102B is combined with the housing part 3102A, and the open portion of the membrane 3104 is sealed (e.g., hot sealed) within the opening 3103, thereby forming the ingestible device 3100.

FIG. 32 shows an ingestible device 3200 for topical delivery. The device 3200 includes housing parts 3202A and 3202B. The housing part 3202B includes a seal 3203. The housing part 3202A is made from a flexible material that is biased against the housing part 3202B and joined to the housing part 3202B by a partial coating 3206 such that housing. The device 3200 also includes a fluid volume 3204 containing a dispensable substance. The subject swallows the ingestible device 3200. When the device 3200 reaches the appropriate location in the GI tract, the partial coating 3206 erodes, degrades and/or dissolves. This causes the flexible housing part 3202A to expand radially so that the housing parts 3202A and 3202B are separated, resulting in topical delivery of the therapeutic agent in the dispensable substance.

FIG. 32B shows aspects of steps in assembling the ingestible device 3200. In step 3220, the housing plug 3212 is formed in the opening 3212 of the housing part 3202A, the membrane 3204 is put inside the housing part 3202A, and the dispensable substance is disposed in the membrane 3204 under aseptic conditions. In step 3222, the housing part 3202B is combined with the housing part 3202A, and the open portion of the membrane 3204 is sealed (e.g., hot sealed) within an opening 3203 in the housing part 3202B, thereby forming the ingestible device 3200.

In certain embodiments, an ingestible device for topical delivery is configured as disclosed in the above-discussion regarding trans-epithelial delivery, but with a relatively large number of nozzles and a relatively large nozzle diameter such that performance properties for topical delivery (discussed above) can be achieved. As an example, in some embodiments, an ingestible device for topical delivery has at least 25 nozzles (e.g., at least 30 nozzles, at least 40 nozzles, 50 nozzles). In some embodiments, such an ingestible device for topical delivery has 30 nozzles, 31 nozzles, 32 nozzles, 33 nozzles, 34 nozzles, 35 nozzles, 36 nozzles, 37 nozzles, 38 nozzles or 40 nozzles. Each nozzle can have a diameter, for example, of at least about 1 mm (e.g., at least about 1.5 mm, at least about 2 mm) and/or at most about 3 mm (e.g., at most about 2.5 mm). For example, in such an ingestible device, each nozzle can have a diameter of from about 1 mm to about 3 mm (e.g., from about 1 mm to about 2.5 mm, from about 2 to 2.5 mm).

Delivery of Therapeutics

Provided herein are ingestible devices and methods that deliver therapeutic agents into the intestinal lumen, mucus, mucosa and/or submucosa by topical, epithelial or trans-epithelial administration to the GI tract of a subject. Current methods of administration for most large molecule therapeutic agents or small molecule therapeutic agents with poor oral bioavailability are subcutaneous (SC), intramuscular (IM), or bolus intravenous (IV) injection targeting the systemic circulation. The devices and methods described herein provide an alternative route of administration to current injectable medications, which can lead to greater convenience and compliance since they minimize or avoid the logistical challenges, patient compliance and adherence challenges, pain, and discomfort associated with traditional routes of administration.

In some embodiments of the devices or methods described herein, the therapeutic is released at a location in the small intestine of the subject. In some embodiments of any of the devices or methods described herein, the location is in the proximal portion of the small intestine (e.g., duodenum or jejunum). In some embodiments of any of the devices or methods described herein, the location is in the distal portion of the small intestine (e.g., jejunum or ileum). In some embodiments of the devices or methods described herein, the therapeutic is released at a location in the large intestine of the subject. In some embodiments of any of the devices or methods described herein, the location is in the proximal portion of the large intestine (e.g., cecum, ascending colon, or transverse colon). In some embodiments of any of the devices or methods described herein, the location is in the distal portion of the large intestine (e.g., transverse colon or descending colon).

In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is triggered by degradation of a release component located in the device. In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is dependent on enzymatic activity at or in the vicinity of the location. In some embodiments of any of the devices or methods described herein, the composition includes a plurality of electrodes including a coating, and releasing the therapeutic is triggered by an electric signal by the electrodes resulting from the interaction of the coating with an intended site of release of the therapeutic. In some embodiments of any of the devices or methods described herein, the release of the therapeutic is triggered by a remote electromagnetic signal. In some embodiments of any of the devices or methods described herein, the release of the therapeutic is triggered by generation in the composition of a gas in an amount sufficient to expel the therapeutic. In some embodiments of any of the devices or methods described herein, the release of the therapeutic is triggered by an electromagnetic signal generated within the device according to a pre-determined drug release profile.

TNFα Inhibitors

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is a TNFα inhibitor. The terms “TNFα inhibitor” or “TNF-alpha inhibitor” refer to an agent which directly or indirectly inhibits, impairs, reduces, down-regulates, or blocks TNFα activity and/or expression. In some embodiments, a TNFα inhibitor is an inhibitory nucleic acid, an antibody or an antigen-binding fragment thereof, a fusion protein, a soluble TNFα receptor (a soluble TNFR1 or a soluble TNFR2), or a small molecule TNFα antagonist. In some embodiments, the inhibitory nucleic acid is a ribozyme, small hairpin RNA, a small interfering RNA, an antisense nucleic acid, or an aptamer.

In other examples, such indirect TNFα inhibitors can be a small molecule inhibitor of a signaling component downstream of a TNFα receptor (e.g., any of the signaling components downstream of a TNFα receptor described herein or known in the art), a small molecule inhibitor of a protein encoded by a TNFα-induced gene (e.g., any protein encoded by a TNFα-induced gene known in the art), and a small molecule inhibitor of a transcription factor selected from the group of NF-κB, c-Jun, and ATF2.

Inhibitory Nucleic Acids of TNFα

Exemplary TNFα inhibitors that are inhibitory nucleic acids targeting TNFα include, e.g., antisense DNA (e.g., Myers et al., J. Pharmacol Exp Ther. 304(1):411-424, 2003; Wasmuth et al., Invest.

Ther. 17(10): 1743-1753, 2009; Ogawa et al., PLoS One 9(3): e92073, 2014; Ding et al., Bone Joint 94-6(Suppl. 11):44, 2014; and Hernandez-Alejandro et al., J. Surgical Res. 176(2):614-620, 2012), and microRNAs (see, e.g., WO 15/26249). In some embodiments, the inhibitory nucleic acid blocks pre-mRNA splicing of TNFα (e.g., Chiu et al., Mol. Pharmacol. 71(6): 1640-1645, 2007).

In some embodiments, the inhibitory nucleic acid, e.g., an aptamer (e.g., Orava et al., ACS Chem Biol. 2013; 8(1): 170-178, 2013), can block the binding of a TNFα protein with its receptor (TNFR1 and/or TNFR2).

In some embodiments, the inhibitory nucleic acid can down-regulate the expression of a TNFα-induced downstream mediator (e.g., TRADD, TRAF2, MEKK1/4, MEKK4/7, INK, AP-1, ASK1, RIP, MEKK 3/6, MAPK, NIK, IKK, NF-κB, p38, INK, IκB-α, or CCL2). Further teachings of downstream TNFα-induced mediators can be found in, e.g., Schwamborn et al., BMC Genomics 4:46, 2003; and Zhou et al., Oncogene 22: 2034-2044, 2003, incorporated by reference herein. Additional aspects of inhibitory nucleic acids are described in Aagaard et al., Adv. Drug Delivery Rev. 59(2):75-86, 2007, and Burnett et al., Biotechnol. J. 6(9):1130-1146, 2011.

In some embodiments, the TNFα inhibitor is an antibody or an antigen-binding fragment thereof (e.g., a Fab or a scFv). In some embodiments, an antibody or antigen-binding fragment described herein binds specifically to any one of TNFα, TNFR1, or TNFR2. In some embodiments, an antibody or antigen-binding fragment of an antibody described herein can bind specifically to TNFα. In some embodiments, an antibody or antigen-binding fragment of an antibody described herein can bind specifically to an TNFα receptor (TNFR1 or TNFR2).

In some embodiments, the TNFα inhibitor can be SAR252067 (e.g., a monoclonal antibody that specifically binds to TNFSF14, described in U.S. Patent Application Publication No. 2013/0315913) or MDGN-002 (described in U.S. Patent Application Publication No. 2015/0337046). In some embodiments, the TNFα inhibitor can be PF-06480605, which binds specifically to TNFSF15 (e.g., described in U.S. Patent Application Publication No. 2015/0132311). Additional examples of TNFα inhibitors include DLCX105 (described in Tsianakas et al., Exp. Dermatol. 25:428-433, 2016) and PF-06480605, which binds specifically to TNFSF15 (described in U.S. Patent Application Publication No. 2015/0132311). Further examples of TNFα inhibitors that are antibodies or antigen-binding antibody fragments are described in, e.g., WO 17/158097, EP 3219727, WO 16/156465, and WO 17/167997.

In some embodiments, the TNFα inhibitor is DLX-105, e.g., the gel formulation.

In some embodiments, the TNFα inhibitor is adalimumab. Adalimumab is a recombinant human IgG1 monoclonal antibody specific for human tumor necrosis factor and is indicated for the treatment of various inflammatory diseases such as rheumatoid arthritis, Crohn's disease, and ulcerative colitis.

Adalimumab is currently delivered as an SC injection of 40 mg in 0.4-0.8 mL once every 1-2 weeks. It is sold in prefilled pen injectors for self-administration. The bioavailability is approximately 64% by SC injection, the half-life is approximately 2 weeks, and intracellular catabolism is the primary mode of elimination. Adalimumab must be refrigerated but can be temporarily stored at room temperature before use.

Adalimumab is a suitable therapeutic for delivery via ingestible device as described herein. It is currently available as a liquid, administered by self-injection, and, because adverse injection site reactions are not uncommon, patients may readily adopt an alternative dosage form. Lastly, the probability of acute reactions to overdose is low which, theoretically, could allow an increase in dose to compensate for lower bioavailability than SC injection.

TNFα Inhibitor Fusion Proteins

In some embodiments, the TNFα inhibitory agent is a fusion protein (e.g., an extracellular domain of a TNFR fused to a partner peptide, e.g., an Fc region of an immunoglobulin, e.g., human IgG) (see, e.g., Peppel et al., J. Exp. Med. 174(6):1483-1489, 1991; Deeg et al., Leukemia 16(2):162, 2002) or a soluble TNFR (e.g., TNFR1 or TNFR2) that binds specifically to TNFα. In some embodiments, the TNFα inhibitor includes or is etanercept (Enbrel™) (see, e.g., WO 91/03553 and WO 09/406,476, incorporated by reference herein). In some embodiments, the TNFα inhibitor includes or is r-TBP-I (e.g., Gradstein et al., J. Acquir. Immune Defic. Syndr. 26(2): 111-117, 2001). In some embodiments, the TNFα inhibitor includes or is a soluble TNFα receptor (e.g., Watt et al., J. Leukoc Biol. 66(6):1005-1013, 1999; Tsao et al., Eur Respir J. 14(3):490-495, 1999; Kozak et al., Am. J. Physiol. Reg. Integrative Comparative Physiol. 269(1):R23-R29, 1995; Mohler et al., J.

Respiratory J. 7(3):515-518, 1994; and Gray et al., Proc. Natl. Acad. Sci. U.S.A. 87(19):7380-7384, 1990).

In some embodiments, the TNFα inhibitor is tulinercept.

TNFα Inhibitor Small Molecules

In some embodiments, the TNFα inhibitor is a small molecule. In some embodiments, the TNFα inhibitor is C87 (Ma et al., J. Biol. Chem. 289(18):12457-66, 2014). In some embodiments, the small molecule is LMP-420 (e.g., Haraguchi et al., AIDS Res. Ther. 3:8, 2006). In some embodiments, the small molecule is a tumor necrosis factor-converting enzyme (TACE) inhibitor (e.g., Moss et al., Nature Clinical Practice Rheumatology 4: 300-309, 2008). In some embodiments, the TACE inhibitor is TMI-005 and BMS-561392. Additional examples of small molecule inhibitors are described in, e.g., He et al., Science 310(5750):1022-1025, 2005.

In some examples, the TNFα inhibitor is a small molecule that inhibits the activity of one of TRADD, TRAF2, MEKK1/4, MEKK4/7, INK, AP-1, ASK1, RIP, MEKK 3/6, MAPK, NIK, IKK, and NF-κB, in a mammalian cell.

Additional examples of ELR chemokine inhibitors that are antibodies or antigen-binding antibody fragments are described in, e.g., U.S. Pat. No. 9,290,570; and U.S. Patent Application Publication Nos. 2004/0170628, 2010/0136031, 2015/0160227, 2015/0224190, 2016/0060347, 2016/0152699, 2016/0108117, 2017/0131282, 2016/0060347, 2014/0271647, 2014/0170156, 2012/0164143, 2010/0254941, 2009/0130110, 2008/0118517, 2004/0208873, 2003/0021790, 2002/0082396, and 2001/0006637, each of which is herein incorporated by reference (e.g., the portions describing ELR chemokine inhibitors).

ELR Chemokine Inhibitor Small Molecules

In some instances, the ELR chemokine inhibitor is, e.g., a small molecule. For example, the ELR chemokine inhibitor can be, e.g., LY-3041658 or repertaxin (Reparixin; DF 1681Y). Additional non-limiting examples of ELR chemokine inhibitors that are small molecules are described in, e.g., U.S. Patent Application Publication Nos. 2007/0248594, 2006/0014794, 2004/0063709, 2004/0034229, 2003/0204085, 2003/0097004, 2004/0186142, 2004/0235908, 2006/0025453, 2017/0224679, 2017/0190681, 2017/0144996, and 2017/0128474, each of which are incorporated by reference (e.g., the portions describing the ELR chemokine inhibitors).

Phosphodiesterase 4 (PDE4) Inhibitors

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is a PDE4 inhibitor. The term “PDE4 inhibitor” refers to an agent which decreases PDE4 activity in vitro or in a mammalian cell, e.g., as compared to the level of PDE4 activity in the absence of the agent; and/or decreases the level of a PDE4 protein in a mammalian cell contacted with the agent, e.g., as compared to the same mammalian cell not contacted with the agent. A non-limiting example of PDE4 activity is the degradation of cAMP.

In some embodiments, a PDE4 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, a PDE4 inhibitor can be an inhibitory nucleic acid.

Inhibitory Nucleic Acids of PDE4

In some embodiments, a PDE4 inhibitor can be an inhibitory nucleic acid. In some embodiments, the inhibitory nucleic acid can be an antisense nucleic acid, a ribozyme, and a small interfering RNA (siRNA).

Another example of an inhibitory nucleic acid is a ribozyme that has specificity for a nucleic acid encoding a PDE4 protein (e.g., specificity for a PDE4 mRNA, e.g., specificity for SEQ ID NO: 1, 2, 3, 4, or 5). 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 a PDE4 mRNA can be designed based upon the nucleotide sequence of any of the PDE4 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 a PDE4 mRNA (see, e.g., U.S. Pat. Nos. 4,987,071 and 5,116,742). Alternatively, a PDE4 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 inhibitor nucleic acid can also be a nucleic acid molecule that forms triple helical structures. For example, expression of a PDE4 polypeptide can be inhibited by targeting nucleotide sequences complementary to the regulatory region of the gene encoding the PDE4 polypeptide (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.

Non-limiting examples of siRNAs targeting PDE4 are described in Takakura et al., PLosOne 10(12):e0142981, 2015; Watanabe et al., Cell Signal 27(7):1517-1524, 2015; Suzuki et al., PLos One 11(7):e0158967, 2016; Kai et al., Mol. Ther. Nucl. Acids 6: 163-172, 2017). See, e.g., Cheng et al. Exp Ther Med. 12(4): 2257-2264, 2016; Peter et al., J Immunol 178)8): 4820-4831; and Lynch et al. J Biolog Chem 280: 33178-33189. Additional examples of PDE4 inhibitory nucleic acids are described in U.S. Patent Application Publication Nos. 2010/0216703 and 2014/0171487, which are incorporated by reference in its entirety.

Heparins

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is a heparin. In some embodiments, the heparin is a low molecular weight heparin.

An exemplary heparin is dalteparin. Dalteparin is a low molecular weight heparin. Like other low molecular weight heparins, dalteparin is used for prophylaxis or treatment of deep vein thrombosis, pulmonary embolism, venous thromboembolism, unstable angina, and non-Q-wave myocardial infarction.

Dalteparin is delivered as an SC injection of 2500-18000 units once or twice daily, depending on the reason for treatment. It is available in single-dose vials, multi-dose vials, and pre-filled syringes for self-administration by the patient. The maximum concentration in currently available formulations is 25,000 units/mL, and many formulations contain only water and HCl/NaOH for pH adjustment. The bioavailability is approximately 8700 by SC injection, the half-life is approximately 3-5 hours, and it is primarily eliminated by the kidneys. Dalteparin is stable at room temperature and studies have demonstrated 30 days stability in commercial off-the-shelf syringes.

The primary risk of dalteparin overdose is uncontrolled hemorrhage at the site of injection. There are few cases of dalteparin overdose in the literature but, in most cases, the patients were discharged after observation without any intervention. One case describes self-administration of 360,000 units of dalteparin that was successfully managed with medical observation followed by discharge from the hospital with no notable sequelae. In the case of overdose, the action of dalteparin may be partially reversed by the administration of protamine sulphate.

Dalteparin is a suitable therapeutic for delivery via ingestible device as described herein. It is currently available as a liquid, administered by self-injection, and, because adverse injection site reactions are not uncommon, patients may readily adopt an alternative dosage form. The primary method of elimination is renal so first-pass through the liver should not present an obstacle to using the DDS. Lastly, the probability of acute reactions to overdose is low which, theoretically, could allow an increase in dose to compensate for lower bioavailability than SC injection. Dalteparin dose is normally specified as a single value based on the condition being treated and the weight range of the patient. Each weight range can span 10-15 kg, suggesting that precise dosing is not critical to achieving therapeutic effect.

Immune Modulators

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is an immune modulator. As used herein, an “immune modulator” or “immune modulatory agent” is an agent that stimulates or suppresses the immune system and can help the body fight cancer, infection, or other diseases. The immune modulator can be a therapeutic agent that decreases the activation of an immune cell (e.g., a T cell, e.g., memory T cell), decreases the secretion or expression of a pro-inflammatory cytokine, decreases the recruitment or migration of T-lymphocytes (e.g., memory T lymphocytes), and/or increases the secretion or expression of an anti-inflammatory cytokine.

In some embodiments, an immune modulator is an antibody or antigen-binding fragment, a nucleic acid (e.g., inhibitory nucleic acid), a small molecule, or a live biotherapeutic, such as a probiotic. In some embodiments, the immune modulator is a herapeutic agent used for the treatment of inflammatory bowel disease (IBD), for example, Crohn's Disease or Ulcerative Colitis (UC). Non-limiting immune modulators that are useful for treating or preventing inflammatory bowel disease include substances that suppress cytokine production, down-regulate or suppress self-antigen expression, or mask MHC antigens.

Non-limiting examples of immune modulators include, without limitation: CHST15 inhibitors (e.g., STNMO1); IL-6 receptor inhibitors (e.g., tocilizumab); IL-12/IL-23 inhibitors (e.g., ustekinumab and brazikumab); integrin inhibitors (e.g., vedolizumab and natalizumab); JAK inhibitors (e.g., tofacitinib); SMAD7 inhibitors (e.g., Mongersen); IL-13 inhibitors; IL-1 receptor inhibitors; TLR agonists (e.g., Kappaproct); stem cells (e.g., Cx601); 2-amino-6-aryl-5-substituted pyrimidines (see U.S. Pat.

Pharmaceutical Formulations

Agents such as antibodies and other therapeutic proteins and the other therapeutic agents disclosed herein can be delivered using the devices and methods described herein, including an ingestible device as disclosed herein. The therapeutic agents can be incorporated into pharmaceutical formulations, which can be loaded into a device for release and delivery to a subject, or more particularly, for delivery of the formulation and/or antibody or therapeutic protein or agent to the gastrointestinal tract of a subject. In some embodiments, the formulation is delivered to the tissue of the GI tract. In some embodiments, the formulation is delivered onto or into tissue of the GI tract, e.g., the mucus, mucosa or submucosa of the GI tract. In some embodiments, the formulations are fluid. In some embodiments, the fluid is a solution or a suspension. In some embodiments, the formulation is a liquid, but can be semi-solid, or solid formulations that are later converted to a liquid formulation. The formulations can comprise the agent and a physiologically acceptable carrier. Some formulations, which may be commercially or otherwise available for IV or subcutaneous delivery, and which may be available in pre-loaded syringes or pens, may alternatively be incorporated or loaded into a device, such as an ingestible device, as disclosed herein, for release and topical delivery of the formulation and/or antibody or therapeutic protein to the gastrointestinal tract of a subject.

In some embodiments, the therapeutic agent is formulated as a solution (e.g., an aqueous solution formulation) or a suspension or dispersion. In some embodiments, the formulation contains an antibody. Formulations can be prepared, for example, by incorporating an antibody in the required amount in an appropriate solvent with at least one, or a combination of, ingredients described herein. Generally, dispersions can be prepared by incorporating an antibody into a vehicle that contains a basic dispersion medium and/or other ingredients. In some embodiments, proper fluidity of a formulation is maintained using an appropriate coating, by the maintenance of the required particle size in the case of dispersion, and/or by the use of surfactants. Prolonged absorption of compositions can be brought about by including in the composition an agent that delays absorption. In some embodiments, formulations further comprise one or more additional excipients to enhance performance, such as tissue or mucosa permeation enhancement, disruption of tight epithelial junctions, absorption and/or stability. Excipients that can be incorporated to enhance absorption by the GI tract and/or at the disease site within the GI tract include, for example, bile salts, chelators, surfactants, anti-oxidants, fatty acids and derivatives thereof, cationic polymers, anionic polymers, and acylcarnitines.

As used herein, the term “insulin” includes animal-derived insulin (such as a bovine, pig, or bovine-pig insulin, for example, as obtained from a bovine or pig pancreas), native human insulin, and recombinant human insulin. The formulation can be a liquid, semi-solid, or solid. In some embodiments, the formulation contains the insulin and a physiologically acceptable carrier.

In some embodiments, the insulin preparation is provided at a concentration of about 40 units/mL to about 500 units/mL (U-40 to U-500). In some embodiments, the insulin is provided at a concentration of about 100 units/mL (U-100). In other embodiments, the insulin is provided at a concentration of about 300 units/mL (U-300). In yet other embodiments, the insulin is provided at a concentration of about 500 units/mL (U-500). In yet another embodiment, there is provided an insulin preparation containing about 40 units/mL (U-40).

In some embodiments, the insulin preparation is an excipient-free insulin.

In other embodiments, the insulin preparation contains one or more excipients. In some embodiments, the insulin preparation is an aqueous formulation comprising the insulin, an aqueous medium, and one or more excipients. In some embodiments, the aqueous medium is water, such as water for injection (WFI), a buffer or a pH-adjusted water. In some embodiments, the buffer is a phosphate buffer. In some embodiments, the water (e.g., the WFI) or the final formulation pH is adjusted to a neutral pH, for example, a pH of about 6.5 to about 8, about pH 6.8 to about 7.8, about pH 7 to about pH 7.8, about pH 7, or more particularly, about pH 7.3 or about 7.4. A mineral acid or base can be used to adjust the pH. In some embodiments, the mineral acid or base is selected from hydrochloric acid (e.g., about 1N to about 2N) and sodium hydroxide (e.g., about 1N to about 2N).

In some embodiments, the one or more excipients is a preservative. In some embodiments, the preservative is a phenolic excipient, such as phenol, m-cresol or a combination thereof.

Bioavailability (AUC) and other measures can be used to assess the pharmacokinetic (PK) characteristics of administration of therapeutics administered according to the devices and methods of the disclosure and compare with other routes of administration. Example PK parameters include plasma half-life (t_1/2(min)), maximum plasma concentration (C_max(pg/mL)), time to maximum plasma concentration (T_max(min)), and clearance rate (CL). For individual drugs, pharmacodynamic (PD) characteristics can be measured and compared with other routes of administration. PD characteristics can be specific to the drug being administered. For example, where insulin is the drug being administered, PD characteristics can include dextrose infusion rate (mg/kg/min) and total amount of glucose (mg/kg) infused (from 20% dextrose infusion) required to maintain the target blood glucose concentration, as well as plasma glucose levels at select time points. Tables 12-14 show the number of capsules needed for a given relative bioavailability % for several exemplary drugs. The asterisk (*) indicates that dosing frequency can be increased to reduce number of capsules per dose, particularly for Humira and Interferon alpha-2b.

Tables 16 and 17 show illustrative dosing regimens for different therapeutics agents delivered with ingestible devices described herein. For the purposes of the tables, the ingestible devices have two different payload sizes: 200 μL in 00-sized device and 400 μL in 000-sized device. The dosing regimens were generated using a model that accounts for different therapeutic agent characteristics (e.g., approved dose, approved dosing frequency, and bioavailability via intravenous (IV), subcutaneous (SC) or intramuscular (IM) administration). The model assumes each drug can be formulated for the device to a maximum concentration of 175 mg/mL. Given the payload size, therapeutic agent characteristics, and a 175 mg/mL drug concentration, bioavailability benchmarks (“Required Bioavailability”) for different dosing regimens (“PGN Regimen”) are shown in the table. For example, as shown in Table 16 for adalimumab, an approved 40 mg subcutaneous injection provides an effective dose of 25.6 mg given adalimumab's subcutaneous bioavailability of 64%. This dose is approved in the U.S. for subcutaneous administration every two weeks. Administration of adalimumab at a concentration of 175 mg/mL using a 000-sized ingestible device with a payload of 400 μL achieves the same effective dose when administered weekly (qwk) given a bioavailability of 18.3%. Likewise, using a 00-sized ingestible device with a payload of 200 μL achieves the same effective dose when administered daily (qd) given a bioavailability of 5.2%. If, for example, the bioavailability for the ingestible device is fixed at 25% for a therapeutic agent, similar calculations can be used to calculate the required drug concentration to achieve a desired effective dose.

Table 17 provides the same information for a different set of therapeutic agents. For non-approved therapeutic agents, dose information was sourced from publicly available clinical trial information. Also, for dose based on patient weight, the assumed weight is 70 kg.

Inflammatory Conditions or Diseases

In some embodiments, the condition or disease that can be treated with the methods and devices disclosed herein is an inflammatory condition or disease. The presently described devices and methods are based, in part, on the unexpected discovery that administration of an immune modulator into the tissue of a subject's gastrointestinal tract can result in the observation of pharmacodynamics effects in tissues beyond the site of deposition. For example, an immune modulator administered into the tissue (e.g., mucosa or submucosa) of a subject's gastrointestinal tract can result in one or more of the following: changes in anatomical features, including suppressed or reduced development, aggregation, or accumulation of one or more of intestinal lymphoid tissues, isolated lymphoid follicles (ILFs), or intestinal lymphoid aggregates; suppressed immune response, including fewer T cells measured in lymph nodes or lymph tissues (which results in greater T cells forced into circulation, i.e., blood); decreased differentiation of immune cells (e.g., as measured using histology or through the use of a sampling device, or using a sampling device); a decreased level of inflammatory cytokine levels (e.g., as measured using biopsy or through the use of a sampling device); decreased endoscopic scoring; and improved efficacy of treatment for IBD (e.g., using any of the clinical assessments of a treatment for IBD described herein) or other inflammatory conditions of the GI tract or endoderm (e.g., in the liver).

In some embodiments, the presently described devices provide for a higher concentration of α4β7 expressing cells in the periphery (e.g., blood) when an immune modulator is delivered into the GI tissue (e.g., mucosa or submucosa) of one or more parts of the GI tract distal to the stomach (e.g., the small or large intestine) as compared to when the same dose of the immune modulator is orally (without a device), intravenously, or subcutaneously administered. The presently described devices can, e.g., result in trafficked cells being forced out of the local gastrointestinal tissue (including the mucosa) and lymph system, and back into systemic circulation of a subject.

Accordingly, also provided herein are methods of treating a disease or condition that arises in a tissue originating from the endoderm. The endoderm forms the gastrointestinal tract, respiratory tract, endocrine glands, and organs, the auditory system and urinary system. Thus, the present disclosure includes compositions and devices for treating diseases and conditions found in the following tissues that originate from the endoderm (e.g., the stomach, the colon, the liver, the pancreas, the urinary bladder, the epithelial parts of the trachea, the lungs, the pharynx, the thyroid, the parathyroid, the intestines, and the gallbladder). Also provided herein are methods of treating a disease or a condition that arises in a tissue originating from the endoderm (e.g., any of the exemplary diseases or conditions that arise in a tissue originating from the endoderm described herein) that include depositing one or more immune modulators into the tissue of the small intestine using any of the devices or compositions described herein. In a preferred embodiment, the compositions, devices and methods are for treating inflammatory diseases and conditions found in the liver (e.g., NAFLD, NASH, or cirrhosis).

Non-limiting examples of an inflammatory disease or condition that arises in a tissue originating from the endoderm includes gastritis, celiac disease, hepatitis, alcoholic lever disease, fatty liver disease (hepatic steatosis), non-alcoholic fatty liver disease (NASH), cirrhosis, primary schlerosing cholangitis, pancreatitis, insterstitial cystitits, asthma, chronic obstructic pulmonary disease, pulmonary fibrosis, pharyngitis, thyroiditis, hyperthyroidism, parathyroiditis, nephritis, Hashimoto's disease, Addison's disease, Graves' disease, Sjögren syndrome, type 1 diabetes, pelvic inflammatory disease, auditory canal inflammation, tinnitus, vestibular neuritis, otitis media, auditory canal inflammation, tracheitis, cholestatic liver disease, primary biliary schlerosis, liver parenchyma, an inherited metabolic disorder of the liver, Byler syndrome, cerebrotendinous, xanthomatosis, Zellweger's syndrome, neonatal hepatitis, cystic fibrosis, ALGS (Alagilles syndrome), PFIC (progressive familial intrahepatic cholestasis), autoimmune hepatitis, primary biliary cirrhosis (PBC), liver fibrosis, NAFLD, portal hypertension, general cholestasis, such as in jaundice due to drugs or during pregnancy, intra- and extrahepatic cholestasis, such as hereditary forms of cholestasis, such as PFIC1, gall stones and choledocholithiasis, malignancy causing obstruction of the biliary tree, symptoms (scratching, pruritus) due to cholestasis/jaundice, chronic autoimmune liver disease leading to progressive cholestasis, and pruritus of cholestatic liver disease, duodenal ulcers, enteritis (radiation-, chemotherapy-, or infection-induced enteritis), diverticulitis, pouchitis, cholecystitis, and cholangitis. Additional examples of diseases and conditions that arise in a tissue originating from the endoderm are known in the art.

In some embodiments of any of the devices or methods described herein, the methods result in the introduction of the immune modulator to one or more of the following, or the PD effects of the immune modulator (e.g., any of the PD effects of immune modulators described herein) are detectable in one or more of the following: throughout or in part of the paraaortic lymph nodes, throughout or in part of the MALT, throughout or in part of the GALT, throughout or in part of the inferior and superior mesenteric lymph nodes, and in one or more sections or subsections of the subject's gastrointestinal tract that is different than the section or subsection of the subject's gastrointestinal tract where the immune modulator is released. In some embodiments of any of the devices or methods described herein, the devices or methods result in the presence or accumulation of the immune modulator in tissues or organs of the endoderm (e.g., the liver) at higher doses as compared to administration of the immune modulator orally (without a device), intravenously, or subcutaneously.

In some embodiments of any of the methods described herein, the methods do not result in (or do not result in a significant effect in) pharmacodynamics effect(s) (e.g., any of the clinical effects or measurements of an immune modulator described herein) outside of the paraaortic lymph nodes.

In any of the methods described herein, the subject can be any mammal (e.g., an animal model of any of the diseases described herein).

In some embodiments of any of the methods described herein, the method results in the suppression of the subject's immune response in one or more of the paraaortic lymph nodes.

In some embodiments of any of the methods described herein, the method results in the suppression of the subject's immune response in mucosa-associated lymphoid tissue (MALT).

In some embodiments of any of the methods described herein, the method results in the suppression of the subject's immune response throughout or in part of the gut-associated lymphoid tissue (GALT). For example, in some embodiments of any of the methods described herein, the method results in a reduction of T cells (e.g., any of the T cells described herein, e.g., memory T cells) in Peyer's patches and/or mesenteric lymph nodes found in the GALT. In some embodiments of any of the methods described herein, the method results in a decreased level of T cells (e.g., any of the types of T cells described herein or known in the art) in a section or subsection of the subject's gastrointestinal tract that is different than the section or subsection of the subject's gastrointestinal tract where the immune modulator is released.

In some embodiments of any of the methods described herein, the method results in the suppression or reduction in the development, the aggregation, or accumulation of one or more of intestinal lymphoid tissues, isolated lymphoid follicles (ILFs), or intestinal lymphoid aggregates in mucosa-associated lymphoid tissue (MALT). In some embodiments of any of the methods described herein, the method results in the suppression of the development of one or more of intestinal lymphoid tissues, isolated lymphoid follicles, or intestinal lymphoid aggregates in gut-associated lymphoid tissue (GALT). In some embodiments of any of the methods described herein, the method results in the suppression of the immune response in one or more sections or subsections of the subject's gastrointestinal tract that is different than the section or subsection of the subject's gastrointestinal tract where the drug is released.

In some embodiments of any of the methods described herein, the methods result in pharmacodynamics effects proximal (“upstream”) to the site of disease in the subject. For example, in some embodiments of any of the methods described herein, the immune modulator is deposited in the tissue of the small intestine (e.g., duodenum or jejunum), but pharmacodynamics effects of the immune modulator are observed in the liver. In some embodiments of any of the methods described herein, the immune modulator is deposited in the tissue of the small intestine (e.g., the duodenum or jejunum) and immune suppression is observed throughout the mesenteric lymph system and other systems of the paraaortic lymph nodes, including the hepatic lymph nodes of the celiac group of the preaortic lymph nodes (preaortic lymph nodes are part of the paraaortic lymph nodes). In some embodiments of any of the methods described herein, the immune modulator is deposited in the small intestine (e.g., duodenum, jejunum, or ileum) or colon (e.g., ascending colon, transverse colon, descending colon, rectum, or cecum), but pharmacodynamics effects of the immune modulator are throughout or in part of the MALT, GALT, Peyer's patches, mesenteric lymph nodes, paraaortic lymph nodes, or any of the other tissues originating from the endoderm described herein or known in the art, in the mammal.

In some embodiments of any of the methods described herein, the method results in a decreased level or a decreased level of activation of one or more of the following immune cells that participate in mucosal immune response in a mammal: microfold cells (M cells), antigen-presenting cells (e.g., B-lymphocytes, dendritic cells, and macrophages), and effector cells (e.g., T-lymphocytes).

Microfold cells (M cells) are found in the gut-associated lymphoid tissue (GALT) of the Peyer's patches in the small intestine. M cells allow for the transport of microbes and particles across the epithelial cell layer from the gut lumen to the lamina propria where interactions with immune cells can take place. M cells provide for the initiation of mucosal immunity responses on the apical membrane by delivering antigens to antigen-presenting cells.

Antigen-presenting cells (APCs) include B-lymphocytes, dendritic cells, and macrophages. B-lymphocytes, also called B-cells, can internalize antigen that binds to their B-cell receptor. Dendritic cells have the broadest range of antigen presentation and are necessary for activation of naïve T cells. Dendritic cells present antigen to both helper and cytotoxic T cells. Macrophages can be stimulated by T-cell secretion of interferon gamma. After this activation, macrophages are able to express major histocompatibility complex (MIC) class II and co-stimulatory molecules, and can present phagocytosed peptide fragments to helper T cells. The activation of macrophages can assist pathogen-infected macrophages in clearing the infection.

MHCs bind antigens derived from pathogens and display them on the cell surface for recognition by appropriate T-cells. MHC class I presents antigens from intracellular pathogens, such as viruses and bacteria. MHC class II presents antigens from phagocytosed/pinocytosed pathogens.

Effector cells, as used herein, include T-lymphocytes, including CD4⁺ (also called helper T cells), CD8⁺ (also called cytotoxic T cells), CD45Rb⁻ (more IL-10 and less TNFα in IBD) as compared with CD4⁺CD45Rb⁺, and CD44⁺ T cells. CD44 participates in lymphocytes activation, recirculation, and homing, and is an indicative marker for effector memory T cells.

In some aspects, the device configured for topical delivery to the GI tract of a subject contains a dispensable substance having a viscosity of from about 0.8 cP to about 10 cP.

It is to be understood that each and any of the foregoing aspects of configuration 3 are freely combinable to deliver the dispensable substance to tissue of the GI tract of a subject via topical delivery.

Based on the present disclosure, the skilled person will appreciate that the physical characteristics of the device are assembled to provide the properties of the device according to the configurations mentioned above. These physical characteristics are discussed further here: As discussed herein, the delivery device comprises a housing. An opening in the housing is configured to fluidly connect the dispensable substance to an environment outside the housing via the opening.

The delivery device also comprises a drive force generator configured to provide a force to the dispensable substance to deliver the dispensable substance through the opening. The drive force generator can be configured to provide an internal pressure as required by the particular device configuration. (As described herein, the drive force generator may comprise a spring, a gas cell, a compressed gas, and a liquid-gas mixture.) The opening in the housing may comprise a nozzle. There may be multiple openings with multiple nozzles. The nozzle(s) can be configured to provide the particular jet properties as required by the particular device configuration. The nozzle and drive force generator can be configured to provide the particular jet properties as required by the particular device configuration.

EXAMPLES
Example 1—Modelling Device Performance

In this Example, modelling was used to determine the performance parameters of an ingestible device for delivering a dispensable substance.

Model

The driving pressure, for a given point in the dose delivery, is related to the delivered liquid volume, and the resulting increase in gas volume, by equations of state for adiabatic expansion. The velocity (e.g., peak jet velocity, average jet velocity, or minimum jet velocity) through the orifice is in turn given by the driving pressure. This is a steady state approximation in which transient effects of fluid acceleration/deceleration are ignored. In other words, the gas expansion is rapid allowing little time for heat transfer/thermal equilibration to the surroundings. Thus, this is treated as an adiabatic (no energy loss).

For an adiabatic process, Pressure P and Volume V of a gas are related as follows, assuming that fluid (liquid) pressure is equal to gas pressure (frictionless piston).

$\frac{P_{2}}{P_{1}} = {(\frac{V_{1}}{V_{2}})}^{γ},$

where P is pressure, V is volume, and γ is the ratio of specific heats.

Pipe shear pressure is given by the Darcy-Weisbach equation:

$P_{Pipe} = f \frac{ρ {Lv}_{o}^{2}}{2 d_{o}},$

where ρ is the density of a liquid, L is the nozzle length, υ_ois the velocity through the nozzle orifice, d_ois the diameter of an nozzle orifice, and f is the Darcy friction factor for pipe flow.

The friction factor for rough pipes is given by:

$\frac{1}{f^{1 / 2}} = - 2.0 \log (\frac{ϵ / d_{o}}{3.7} + \frac{2.51}{{Ref}^{1 / 2}}),$

where ϵ is the pipe surface roughness, and Re is the Reynolds number for the fluid.

Haaland proposed the following explicit approximation, which differs by less than 2% from Colebrook:

$f^{- 1 / 2} = \frac{1}{f^{1 / 2}} = - 1.8 \log ({(\frac{ϵ / d_{o}}{3.7})}^{1.11} + \frac{6.9}{Re})$

$f = \frac{1}{{(- 1 .8 \log ({(\frac{ϵ / d_{o}}{3.7})}^{1.11} + \frac{6.9}{Re}))}^{2}}$

Therefore, pipe pressure is:

$P_{Pipe} = \frac{ρ {Lv}_{o}^{2}}{2 {d_{o} (- 1 .8 \log ({(\frac{ϵ / d_{o}}{3.7})}^{1.11} + \frac{6.9}{Re}))}^{2}}$

This explicit approximation requires iterative solution if Re is unknown.

Pipe exit and entry losses are assumed as being given by:

P
_Entry=1/2C_Entryρ_lv²

P
_Exit=1/2C_Exitρ_lv²

Thus, overall pressure drop across the orifice is:

$P_{Orifice} = f \frac{ρ {Lv}_{o}^{2}}{2 d_{o}} + \frac{1}{2} (C_{Entry} + C_{Exit}) ρ_{l} v_{o}^{2},$

Where C_entryis the coefficient of discharge on entry, and C_exitis the coefficient of discharge on exit.

The total flowrate is:

Q=Nπd
_o
²
v
_o,

where Q is the volumetric flow rate through a single orifice.

Accounting for piston friction, the liquid delivery pressure through the orifice is related to the gas pressure as follows. The force balance on the piston is given by:

$\frac{π}{4} d_{Piston}^{2} (P_{gas} - P_{Liquid}) - F_{Friction} = a_{Piston} m_{Piston}$

Applying a steady state assumption yields:

$\frac{π}{4} d_{Piston}^{2} (P_{gas} - P_{Liquid}) - F_{Friction}$

Rearranging, results in:

$P_{Orifice} = P_{gas} - \frac{F_{Friction}}{\frac{π}{4} d_{Piston}^{2}}$

The jet impact force is given by the rate of change of the jet momentum at the impact surface:

F=dp/dt=d(mv)/dt=v(dm/dt)+m(dv/dt),

Where p is momentum, v is velocity and m is mass.

Assuming constant jet velocity for a given time step, the dV/dt term goes to zero, yielding:

F=V(dm/dt),

F=velocity*mass flow rate

F=density*area*velocity{circumflex over ( )}2

F=1/4*pi*density*diameter{circumflex over ( )}2*velocity{circumflex over ( )}2

The jet power has been shown to correlate with needle-free penetration and dispersion by:

Power=1/4*pi*density*diameter{circumflex over ( )}2*velocity{circumflex over ( )}3

Example 2—Jet Velocity Measurements

A high-speed video camera (Photron Fastcam SA3, using 2,000 frames per second) was used to measure the jet velocities of a dispensable substance (water) delivered from devices having different nozzle diameters and nozzle lengths. The receiving medium (external environment) was air. The nozzles were made of MicroFine Green Resin (an ABS-like material), using micro-resolution stereolithography (SLA).

The results are shown in Tables 27 and 28. The first 12 nozzles in Table 27 correspond to nozzles depicted in FIGS. 6A-6L, respectively.

Example 3—Comparison of PK/PD of Human Insulin Delivered by Subcutaneous or Jet Delivery in the Jejunum Using Euglycemic Clamp Technique in Swine

A study was carried out to compare the pharmacokinetics (PK) and pharmacodynamics (PD) of regular human insulin (NOVOLIN® R) in swines after subcutaneous (SC) administration or intra-jejunal (IJ) administration via a single nozzle jet delivery device.

A total of 18 Yorkshire female swine in good health and weighing 60-70 kg each were included in this study. Swine were divided into two groups with 9 animals per group. All 9 animals in group 01 were administered a single subcutaneous injection of insulin aspart (NOVOLIN® R) (˜40 U) on one side of the neck at a depth of ˜5 mm. A sham surgical laparotomy was performed. All 9 animals in group 02 were administrated regular human insulin (NOVOLIN®R) (˜40 U) delivered in the proximal jejunum by a jet delivery device placed by surgical laparotomy. The jet delivery device was configured with the single nozzle in an axial orientation. The device was held in place during the laparotomy insertion, and the nozzle outlet was directed to face the jejunal wall to direct the jet of the NOVOLIN® R to the GI tract. The device was pre-pressurized with compressed gas to have an internal pressure of about 225 psi, except where noted.

All animals were fasted overnight prior to the NOVOLIN® R administration. Swine were divided into two groups with 9 animals per group. Prior to NOVOLIN® R administration, the animals were anesthetized, and two vascular access catheters were placed. In all 18 animals, a laparotomy procedure was performed to expose the abdominal cavity. Animals remained under anesthesia during the entire procedure for the PK/PD study.

All 9 animals in group 01 were administered a single subcutaneous injection of insulin aspart (NOVOLIN® R) (˜30 U) on one side of the neck at a depth of 5 mm.

All 9 animals in group 02 were dosed with regular human insulin (NOVOLIN® R) in the proximal jejunum by the single nozzle jet delivery device placed by surgical laparotomy.

For the laparotomy in group 02, a small segment of the jejunal mucosa and serosa was exposed by midline laparotomy and the jet delivery device was inserted through antimesenteric incision. Regular human insulin NOVOLIN® R (˜40 U) was delivered by the jet delivery device, and the bowel and abdominal wall was closed.

For PK/PD blood collections, blood (approximately 3 mL, EDTA) samples were collected at −20, −10, 0, 10, 20, 30, 40, 50, 60, 75, 90, 105, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, and 420 minutes after dosing. Blood samples were kept on wet ice until centrifugation and separation of plasma. The plasma samples were stored −80° C. on the days of collection until delivered to AHDC Endocrinology Laboratory at Cornell University for insulin analyses. Glucose was monitored every five (5) minutes during the study by portable glucose analyzer (StatStrip (SS) hospital glucose monitoring system (Nova Biomedical, Waltham, Mass.)). At each time point, approximate 0.1 mL of blood was drawn and immediately placed on a glucose monitoring test strip, and the whole blood glucose concentration was measured by the SS in triplicate.

A euglycemic clamp procedure (ECP) was employed to compare pharmacokinetics and pharmacodynamics of regular human Insulin (NOVOLIN® R) delivered subcutaneously (SC) in the neck versus intra-jejunally (IJ) by the jet delivery device in the small intestine. ECP was used to quantify the amount of glucose required to maintain normoglycemia after exogenous bolus of insulin. ECP allowed both the glucose infusion rate (20% dextrose infusion) and total quantity to be calculated, which represented the effect of exogenous insulin on the disposition of blood glucose. ECP ensured pharmacologic suppression of the production of endogenous insulin. This study evaluated serum insulin concentration (pg/mL) over time and glucose infusion rate (to maintain a constant ˜85 mg/dl BG) over the duration of the ECP (7 hours; 420 min.). The animals were anesthetized for the entire ECP. The endpoints included a comparison of selected pharmacokinetic parameters for insulin, including t_1/2(min), C_max(pg/mL), T_max(min) and AUC_0-420min(ng·h/mL), as well as pharmacodynamic parameters such as the rate (mg/kg/min) and amount of glucose (mg/kg) infused.

At the end of the study, all animals were euthanized and animals in group 02 underwent gross necropsy for histopathologic evaluation of the proximal jejunum where the NOVOLIN® R was administrated.

Results

FIG. 48 and FIG. 49 show blood insulin levels for each animal. The area under the concentration-time curve (AUC_{0-420 min}) of the blood insulin, maximum plasma concentration C_max(uIU/mL), and time to maximum plasma concentration (T_max) were calculated for each animal.

FIG. 50 and FIG. 51 show blood insulin levels (uIU/mL) and dextrose infusion rates (mg/min/kg) in SC and IJ administration groups, respectively.

Blood insulin results for SC and IJ administrations are shown in Tables 29 and 30, respectively.

*: Results from animal 18P29 and 18P24 were excluded from blood insulin PK analysis, blood glucose analysis, and Dextrose infusion calculation; animal 18P29 received only 30 U insulin, while animal 18P24 received 30 U insulin at 150 psig. Animal 18P18 was also excluded from the blood insulin calculation due to unknown abnormal results as compared with all the other animals.

The mean blood glucose level in SC administration group was 83.5 mg/dL, which was very similar to IJ administration group (89.6 mg/dL). The mean dextrose infusion rate was higher in the IJ administration group in the first 70 minutes after Novolin® R administration. From 75 minutes to 420 minutes post-Novolin® R administration, the mean dextrose infusion rate was higher in the SC administration group.

The AUC and the maximum plasma concentration C_maxin the SC administration group was higher than that of the IJ administration group. The time to maximum plasma concentration (T_max) was 55.63 minutes in jejunum administration group whereas in the subcutaneous administration group, T_maxwas 87.14 minutes.

The blood insulin level in animal 18P18 (SC administration group) was significantly higher than the rest of the animals in the group. The reason was unknown. The blood insulin levels post-dosing in animal 18P17 and 18P22 were similar to the baseline indicating that IJ administration of the Novolin® R via the jet delivery device in these animals may not have been successful.

Example 4—Evaluation of Target Internal Pressure Range for Submucosal Delivery Using an Ingestible 2-Nozzle Jet Delivery Device by Bench Test Jetting of India Ink into Porcine Jejunal Tissue Ex Vivo

A study was conducted to identify the internal pressure range for trans-epithelial delivery of a drug payload into porcine jejunal submucosal tissue ex vivo using India ink as a drug surrogate.

Test Article

India Ink was used in this study.

Ingestible Device Configuration

Each ingestible device used in this study was configured as a capsule containing a substance reservoir (volume: 450 μL); two (2) gas reservoirs; a check valve; a floating piston; two (2) nozzles radially configured 180 degrees apart; a lid at one end of the capsule; and a pneumatic control line ((polyetheretherketone (PEEK) tubing) attached to the lid). The first gas reservoir was positioned behind the substance reservoir and was used to drive the substance (India ink) from the substance reservoir. The floating piston separated the substance reservoir from the first gas reservoir. The second gas reservoir was positioned beneath the lid and used only to open the lid. Although it was previously demonstrated that a single pressurized gas reservoir can be used to both open the lid and eject the substance (e.g., drug; data not shown), the use of two separate gas reservoirs in this study was intended to demonstrate independent assessment of the action of the triggering mechanism (lid opening) and the substance ejection parameters.

Configuration of ingestible device with tissue: Porcine jejunum tissue, previously flash frozen in liquid N₂and then stored at −80° C., was thawed and used as the source tissue for testing. In a biological safety cabinet, one side of the jejunum was sealed with a zap strap and stopper. The ingestible device was then inserted into the lumen of the jejunum. Finally, a zap strap fixed the proximal portion of the jejunum to the pneumatic control line.

Device pressurization: An external pressure chamber was connected to an air compressor. Two pressure gauges were used: one was fitted onto the air compressor and a second NIST-certified pressure gauge was placed in-line with the pressure chamber and the air compressor.

The first and second gas reservoirs of each device were pressurized separately. To pressurize the first gas reservoir, the device was placed in the pressure chamber and then pressurized to its target internal pressure (200 psig to 350 psig). The pressure chamber was then depressurized back to ambient atmospheric pressure. The ingestible device was then removed from the chamber, after which it maintained the target internal pressure by way of the check valve. To pressurize the second gas reservoir, the ingestible device control line was directly attached to the air compressor via an in-line valve. The valve was turned manually to pressurize the second gas reservoir to 350 psig.

Ex Vivo Jetting Study Protocol and Results

Briefly, a total of five (5) capsules were used in this study and a single ingestible device was used per test. Prior to testing, each ingestible device (attached to the control line) was filled with a 450 μL payload of substance (India ink). The first gas reservoir was then pressurized with air to its target internal pressure of 200 psig, 250 psig, 300 psig or 350 psig, as described above; the pressure was read from the in-line NIST gauge, which was in agreement with the pressure reading from the air compressor gauge. At the time of testing, the pressurized device configured with tissue was placed within a blast shield. Then the second gas reservoir (initially at ambient atmospheric pressure) was quickly pressurized to 350 psig, as described above. Pressurizing the second gas reservoir opened the lid, exposing the ingestible device nozzles. The internal pressure in the first gas reservoir ejected the India ink from the substance reservoir through the two (2) radially-configured nozzles towards the porcine jejunum tissue surrounding the ingestible device. Pre- and post-deployment device weights and diameters were recorded throughout the study to confirm proper device loading/dispensing volumes and pressurization, respectively. The jejunal tissue was then removed from the ingestible device and rinsed in 10% neutral buffered formalin (NBF) and deionized water for photography. The deployed device was disinfected and dried prior to obtaining its post-pressurization weight.

Pressure tests were performed at 200 psig, 250 psig, 300 psig and 350 psig, and visual observations were made after washing the tissue. The results are summarized in Table 31. The test result was assigned as PASS if the substance delivered from the device passed through the jejunal tissue without tissue rupture or blow through of ink to the outside of the jejunal tissue, or FAIL if the substance delivered from the device was not observed to pass through the jejunal tissue or if tissue rupture or blow through of ink to the outside of the jejunal tissue occurred.

Example 5—Identification of the Target Internal Pressure Range of an Ingestible 2-Nozzle Jet Delivery Device by Evaluating the Bioavailability of Adalimumab in Female Yorkshire Pigs

A study was conducted to identify the target internal pressure range of an ingestible 2-nozzle jet delivery device required to achieve systemic uptake of adalimumab. In this study, the plasma pharmacokinetics of adalimumab were evaluated in female Yorkshire pigs after intravenous (IV), subcutaneous (SC), or intraduodenal (ID) administration via an endoscopically placed ingestible device.

Test Article

Adalimumab in an aqueous buffer having an adalimumab concentration of about 106 mg/mL.

Ingestible Device Configuration

Each ingestible device was configured as a capsule comprising a substance reservoir; a gas reservoir; a one-way duckbill valve; a piston; two nozzles radially configured 180 degrees apart; two shear pins on opposite sides of the capsule (0.9 mm in diameter, 2.5 mm in length); and a pneumatic control line (polyetheretherketone (PEEK) tubing) attached at one end of the device to allow for remote pneumatic triggering and release of the test article from the ingestible device. The shear pins were brittle 3D-printed polymer materials having finite (shear) strength sufficient to hold back the internal force in the gas reservoir. To use the ingestible device, the substance reservoir is charged with the test article; the gas reservoir is charged with a gas (via the one-way duckbill valve) to provide the drive force for ejecting the test article fluid from the ingestible device as a jet; the pneumatic control line allows for pneumatic triggering and release of the test article from the ingestible device; the shear pins restrain the force provided by the compressed gas and are broken by pneumatic impulse applied via the pneumatic control line; breakage of the shear pins allows the stored/applied pressure to open the nozzles quickly and form the jet.

Shortly before use, each ingestible device was pressurized by placing it in a pressure chamber and attaching the pressure chamber to an air compressor. The target pressure was set to 320 psig, 270 psig, or 220 psig, and the pressurized air was stored in the ingestible device gas chamber and retained via the one-way duckbill valve. After pressurizing the ingestible device, a seal plug was applied to the duckbill valve and glued with cyanoacrylate.

Nominally, 0.450 mL of test article was loaded into the substance reservoir of the ingestible device using a manual fill procedure. The ingestible device was weighed before and after loading with test article and the actual amount of test article loaded into the ingestible device was determined. The ingestible device loaded with test article was then shipped to the in vivo study site for use within one week of loading with test article. After test article delivery to the study subject was completed, the ingestible device was weighed again, and the amount of test article delivered was determined. Typically, approximately 0.050 mL was retained in the ingestible device after test article delivery was completed. Thus, approximately 0.400 mL of test article was dispensed from each ingestible device.

A summary of parameters for the delivery of the test article via the ingestible device is provided in Table 32. Initial and final refer to values at the beginning and end of the dispensing period for the test article, respectively

Animals were housed two per cage and fasted for a minimum of 12 hours prior to dosing. Food was returned at 4 hours post-dose. Water was supplied ad libitum. The dosing was as follows: Dose day 1: group 1 (n=3), and group 3 (n=2); Dose day 2: group 2 (n=3), and group 1 (n=2); Dose day 3: group 3 (n=3), and group 2 (n=2); Dose day 4: groups 4 (n=3), and group 5 (n=3). Following the 240-hour post-dose blood collection the animal was euthanized via euthanasia solution IV bolus dose.

Routes of Administration

For intraduodenal (ID) administration, the ingestible device was attached to an endoscope (Olympus OSF-V60 attached to an Olympus CV60 Tower) via a working channel and maneuvered into the pyloric sphincter with camera visualization to identify the third (inferior/horizontal) part of the duodenum (D3). Following confirmation of placement of the ingestible device in the correct region, the endoscope was retracted out of the pyloric sphincter, leaving the ingestible device in the D3 region of the duodenum. After pausing and observing relaxation of the intestinal walls and obscured vision to the ingestible device, the ingestible device was triggered via the pneumatic control line to deliver the test article to the duodenum. After releasing the dose, the endoscope was advanced again for visual observation of the injection site. The capsule and endoscope were then retracted out of the body.

For intravenous (IV) administration, the test article was administered intravenously via bolus dose into the marginal ear vein followed by a 1 mL flush with saline if necessary.

For subcutaneous (SC) administration, animals were placed in dorsal recumbence and the SC injection site asceptically prepared with alcohol. The test article was administered as an SC injection into a “skin tent” on the belly of the pig.

Sampling and Analysis

Plasma samples were collected at pre-dose, 1, 3, 6, 8, 24, 72, 144, and 240 hours post-dose in all animals. Each blood sample was collected from the pig jugular vein, or other suitable vessel via direct venipuncture, placed into a chilled tube containing K2-EDTA as the anticoagulant, and inverted several times to mix. Blood samples were kept on wet ice until centrifugation. Blood samples were centrifuged at a temperature of 4° C., at 3,000×g, for 5 minutes and chilled throughout processing. Plasma was collected into pre-labeled polypropylene tubes and placed in a freezer set to maintain −60 to −80° C. prior to analysis.

Samples were processed and analyzed by using an adalimumab (anti-TNF-alpha) ELISA kit from Alpha Diagnostics, Inc. (Catalog #200 310-AHG). All plasma samples were diluted by 1:100 dilution. Plasma samples were reanalyzed with a 1:1000 dilution from animals 6287, 6289, 6332, 6334, 6336, 6149, 6335, and 6337. Plasma samples close to the lower limit of quantification (LLOQ) were repeated with a 1:5 dilution from animals 6138 and 6137. The final concentrations of adalimumab in these two animals were lower than previously shown, suggesting that these values were at the limits of detection and were not reliable. Therefore, the data from animal 6138 and 6137 were not included in the final PK analysis. All data and pharmacokinetic parameters were analyzed and graphed by using GraphPad Prism version 7.00 for Windows, GraphPad Software, La Jolla Calif. USA, www.graphpad.com (GraphPad Prism 7). The area under the concentration curve (AUC) was calculated with the trapezoidal rules.

Results

The results are summarized in Table 34. FIG. 52 charts the adalimumab plasma concentration over 10 days for each group.

Example 6—Evaluation of the Bioavailability of Dulaglutide after Intraduodenal Administration Via an Ingestible 2-Nozzle Jet Delivery Device in Female Yorkshire Pigs

A study was performed to determine the plasma pharmacokinetics of dulaglutide in female Yorkshire pigs after intravenous (IV), subcutaneous (SC), or intraduodenal (ID) administration via an endoscopically placed ingestible device.

Test Article

TRULICITY® (dulaglutide solution) having a dulaglutide concentration of 1.5 mg/0.5 mL (i.e., 3 mg/mL) was used in this study. Dulaglutide is a long-acting glucagon-like peptide 1 (GLP-1) receptor agonist having a molecular weight of about 63 kDa. The molecule consists of 2 identical disulfide-linked chains, each containing a modified human GLP-1 analogue sequence covalently linked to a modified human immunoglobulin G4 (IgG4) heavy chain fragment (Fc) by a small peptide linker. The GLP-1 analogue portion of dulaglutide is approximately 90% homologous to native human GLP-1 (7-37).

Ingestible Device Configuration

Shortly before use, each ingestible device was pressurized by placing it in a pressure chamber and attaching the pressure chamber to an air compressor. The target pressure was set to 320 psig, and the pressurized air was stored in the ingestible device gas chamber and retained via the one-way duckbill valve. After pressurizing the ingestible device, a seal plug was applied to the duckbill valve and glued with cyanoacrylate.

A summary of parameters for the delivery of the test article solution via the ingestible device is provided below. Initial and final refer to values at the beginning and end of the dispensing period for the test article, respectively.

In Vivo Study Design

A total of 11 healthy female Yorkshire pigs (Sus scrofa domesticus) were used for the study: n=5 for ID administration, n=3 for IV administration, and n=3 for SC administration. Each pig weighed between about 25-30 kg at the initiation of the study. A 1.2 mg (˜0.04 mg/kg) dose of the dulaglutide solution was administered to each pig by either ID administration via the endoscopically placed ingestible device (Group 1), IV administration (Group 2), or SC administration (Group 3). The study design is shown below in Table 35.

Dulaglutide solution was administered at t=0 on the day of dosing. The animals were anesthetized with an intramuscular injection of a cocktail containing ketamine (approximately 10-20 mg/kg), xylazine (approximately 1-2 mg/kg) and atropine (approximately 0.02-0.04 mg/kg). The animals were intubated and maintained using isoflurane (approximately 3-5% in oxygen 1 to 4 L/min) as necessary until dosing was complete. The animals were wakened post dose.

Routes of Administration

For intravenous (IV) administration, the test article was administered intravenously via bolus dose into the marginal ear vein followed by a 1 mL flush with saline if necessary.

For subcutaneous (SC) administration, the test article was administered into the dorsal subcutaneous space directly at the base of the pig. Dose sites were gently shaved and circled with marker pen for identifying the injection site.

Sampling

Each blood sample (˜2.0 mL) were taken from the jugular vein (or other suitable vessel) of each pig via direct venipuncture. The samples were collected into chilled tubes with K2EDTA as the anticoagulant, and inverted several times to mix. Blood samples were kept on wet ice until centrifugation. The blood samples were centrifuged at a temperature of 4° C., at 3,000×g, for 5 minutes. All samples were maintained chilled throughout processing. Plasma was collected into pre-labeled 2-mL microcentrifuge tubes and placed in a freezer set to maintain a temperature of −60° C. to −80° C. until further analysis by ELISA assay. The samples were taken prior to dosing, then again at 1, 3, 6, 8, 24, 72, 144, and 240 hours post-dose and sent to an off-site laboratory for bioanalytical analysis. Following the 240 hour post dose blood collection, the animals were euthanized via euthanasia solution IV bolus dose.

Analysis

Samples were processed and analyzed by using an enzyme-linked immunosorbent assay (ELISA) modified from a validated ELISA method for detecting dulaglutide in monkey serum (Vahle et al., Toxicol. Pathol. 43:1004-1014, 2015).

Briefly, 96-well microtiter plates were coated with mouse anti-human IgG (Fc) antibody (0.5 μg/mL) (Southern Biotech, Birmingham, Ala.) to capture dulaglutide in swine plasma. Dilutions of dulaglutide standards, quality control samples, and test samples were prepared in 10% swine plasma. Following preparation, the samples were incubated on the coated plates for 1 h at room temperature. The dulaglutide complex on the plate was bound with a mouse IgG2a kappa anti-GLP-1 antibody (ThermoFisher Scientific, Waltham, Mass.) and then detected using a mouse anti-mouse IgG2a-horseradish peroxidase (IgG2a-HPR) (Bethyl, Montgomery, Tex.) with tetramethylbenzidine (TMB) substrate. The standard curve ranged from 4.0-0.031 ng/mL, with 0.31 ng/mL being the lowest limit of quantitation. All plasma samples were diluted by 1:10, 1:50, or 1:100 depending on the concentration of the drug. All data and pharmacokinetic parameters were analyzed and graphed using GraphPad Prism version 7.00 for Windows, (GraphPad Software, La Jolla Calif. USA). The area under the concentration curve (AUC) versus time was calculated with the trapezoidal rules from the first sample collection time points (pre-dose, time 0) to last time point of sample collection (240 h post-dose) ((AUC)_T0-T240h)).

Non-compartmental analysis was used to determine PK parameters for each subject. AUC_T0-T240h, half-life, clearance, C_maxand T_maxwere determined for each subject. The bioavailability of dulaglutide via ID administration (Group 1) in comparison to the IV (Group 2) and SC (Group 3) administrations was determined.

Results

The results of the study are shown in Table 36 and in FIGS. 53A-53C and FIG. 54. FIGS. 53A-53C show the dulaglutide concentration in blood over time after: ID administration via the endoscopically placed ingestible device (FIG. 53A); SC administration (FIG. 53B); and IV administration (FIG. 53C). The plasma level of dulaglutide in one animal in Group 1 (no. 8487; ID) was below the limit of detection of the ELISA assay. Data obtained from this animal were excluded from subsequent bioavailability determinations. Prior to exclusion of these data, the ratio of the area under a curve (AUC) of the therapeutic agent concentration in systemic circulation versus time that was achieved when the drug was administered by the ID route (AUC_ID(ng·hr/mL±SEM)) was 3890.00±94.73.

The bioavailability of dulaglutide via ID administration was determined relative to IV or SC administration. The results are shown in FIG. 54. For ID administration, the bioavailability relative to IV administration [(AUC)_ID/IV*100%] was about 33%, while the bioavailability relative to SC administration [(AUC)_ID/SC*100%] was about 61%.

Example 7—Identification of the Target Internal Pressure Range of an Ingestible 4-Nozzle Jet Delivery Device by Evaluating the Bioavailability Adalimumab after Intraduodenal (ID) Administration to Female Yorkshire Pigs

A study was conducted to identify the target internal pressure range of an ingestible 4-nozzle jet delivery device required to achieve systemic uptake of adalimumab. In this study, the plasma pharmacokinetics of adalimumab were evaluated in female Yorkshire pigs after intraduodenal (ID) administration via an endoscopically placed ingestible device. The results were compared with those obtained after administration of adalimumab via a 2-nozzle jet delivery device, SC or IV (Example 5).

Test Article

Adalimumab in an aqueous buffer having an adalimumab concentration of about 106 mg/mL.

Ingestible Device Configuration

Each ingestible device was configured as a capsule comprising a substance reservoir; a gas reservoir; a one-way duckbill valve; a piston; four nozzles radially configured 90 degrees apart; two shear pins on opposite sides of the capsule (0.9 mm in diameter, 2.5 mm in length); and a pneumatic control line (polyetheretherketone (PEEK) tubing) attached at one end of the device to allow for remote pneumatic triggering and release of the test article from the ingestible device. The shear pins were brittle 3D-printed polymer materials having finite (shear) strength sufficient to hold back the internal force in the gas reservoir. To use the ingestible device, the substance reservoir is charged with the test article; the gas reservoir is charged with a gas (via the one-way duckbill valve) to provide the drive force for ejecting the test article fluid from the ingestible device as a jet; the pneumatic control line allows for pneumatic triggering and release of the test article from the ingestible device; the shear pins restrain the force provided by the compressed gas and are broken by pneumatic impulse applied via the pneumatic control line; breakage of the shear pins allows the stored/applied pressure to open the nozzles quickly and form the jet.

Shortly before use, each ingestible device was pressurized by placing it in a pressure chamber and attaching the pressure chamber to an air compressor. The target pressure was set to 320 psig or 350 psig, and the pressurized air was stored in the ingestible device gas chamber and retained via the one-way duckbill valve. After pressurizing the ingestible device, a seal plug was applied to the duckbill valve and glued with cyanoacrylate.

A summary of parameters for the delivery of the test article via the ingestible device is provided in Table 37. Initial and final refer to values at the beginning and end of the dispensing period for the test article, respectively.

(Day 10 post

Animals were housed two per cage and fasted for a minimum of 12 hours prior to dosing. Food was returned at 4 hours post-dose. Water was supplied ad libitum. The dosing was as follows: Dose day 1: group 1 (n=2), and group 2 (n=3); Dose day 2: group 2 (n=3), and group 1 (n=2). Following the 240-hour post-dose blood collection the animals were euthanized via intramuscular bolus dose of euthanasia solution.

Intraduodenal (ID) administration was performed as follows. The ingestible device was attached to an endoscope (Olympus OSF-V60 attached to an Olympus CV60 Tower) via a working channel and maneuvered into the pyloric sphincter with camera visualization to identify the third (inferior/horizontal) part of the duodenum (D3). Following confirmation of placement of the ingestible device in the correct region, the endoscope was retracted out of the pyloric sphincter, leaving the ingestible device in the D3 region of the duodenum. After pausing and observing relaxation of the intestinal walls and obscured vision to the ingestible device, the ingestible device was triggered via the pneumatic control line to deliver the test article to the duodenum. After releasing the dose, the endoscope was advanced again for visual observation of the injection site. The capsule and endoscope were then retracted out of the body.

Sampling

Each blood sample was collected from the pig jugular vein, or other suitable vessel via direct venipuncture, placed into a chilled tube containing K2-EDTA as the anticoagulant, and inverted several times to mix. Blood samples were kept on wet ice until centrifugation. Blood samples were centrifuged at a temperature of 4° C., at 3,000×g, for 5 minutes and chilled throughout processing. Plasma was collected into pre-labeled polypropylene tubes and placed in a freezer set to maintain −60 to −80° C. prior to analysis.

Plasma samples were collected at pre-dose, 1, 3, 6, 8, 24, 72, 144, and 240 hours post-dose in all animals and sent to an off-site laboratory for bioanalytical analysis. Samples were processed and analyzed by using an adalimumab (anti-TNF-alpha) ELISA kit from Alpha Diagnostics, Inc. (Catalog #200 310-AHG). All plasma samples were diluted by 1:100 dilution. Diluted samples were processed in duplicates and the mean Optical Density (O.D.) was measured using a SpectraMax plate reader and utilizing SoftMax Pro software for analysis. The Lower Limit of Quantification (LLOQ) was calculated by adding IOX the standard deviation value of the blanks O.D. to the average of the blank standard O.D. values. Mean concentrations of adalimumab were back interpolated to a 4-parameter log fit standard curve and subsequently multiplied by the dilution factor to obtain a final corrected adalimumab concentration. All data and pharmacokinetic parameters were analyzed and graphed by using GraphPad Prism version 7.00 for Windows, GraphPad Software, La Jolla Calif. USA, www.graphpad.com (GraphPad Prism 7). The area under the concentration curve (AUC) was calculated with the trapezoidal rules.

Results

The plasma concentrations of adalimumab over time in individual animals are shown in FIGS. 55A-55B. FIG. 55A represents animals treated with adalimumab after ID administration via the endoscopically placed ingestible device having 4 nozzles and an internal pressure of 320 psig. FIG. 55B represents animals treated with adalimumab after ID administration via the endoscopically placed ingestible device having 4 nozzles and an internal pressure of 350 psig.

The PK results were compared to a subset of data from Example 5. The bioavailability was determined by comparison with Example 5 control arms (SC and IV administration). The results are summarized in Table 39.

FIG. 56 shows the mean plasma concentration of adalimumab (ng/mL+SEM) over time (0-240 hours) after ID administration via the endoscopically placed ingestible device having: 4 nozzles and an internal pressure of 320 psig (Group 1); 4 nozzles and an internal pressure of 350 psig (Group 2); 2 nozzles and an internal pressure of 320 psig (Example 5, Group 3).

Example 8—Evaluation of the Stability and Integrity of Adalimumab After Delivery via an Ingestible Device The effects that various drug dispensing variables, such as nozzle geometry and delivery pressure, have on the structure and function of the target drug adalimumab were evaluated. Delivery pressures up to 300 psi and nozzle dimensions down to 0.35 mm diameter were tested.

The experimental design is as follows. Briefly, a drug (adalimumab) was loaded into a jet device including a piston with a release mechanism. On the back side of the piston, pressure was provided by a hand pump, and the release mechanism was released to release the drug. The end fastener was screwed on to secure the nozzle insert and seal the chamber. The jet device was operated at a target pressure to dispense the drug into a polypropylene tube for collection and analysis. For the minimum pressure test, the jet was operated manually by slowly pushing the piston forward to dispense the drug. For the maximum pressure test, 300 pounds per square inch gauge (psig) were applied to the jet device, and the drug was carefully dispensed into a polypropylene collection tube. After each dose was delivered, the remaining gas pressure was relieved, and the nozzle was cleaned.

Target Binding

Tests were conducted to determine whether certain pressures and nozzle diameters used to deliver adalimumab with an ingestible device would result in physical damage to the drug and affect target drug binding.

Test Method

The drug (adalimumab) was loaded into the ingestible device and fired through a nozzle with varying diameters at various pressure conditions. Table 40 summarizes the samples and delivery conditions used.

The drug was extracted utilizing the respective dispensing systems and tested by a competitive inhibition assay as described in Velayudhan et al., “Demonstration of functional similarity of proposed biosimilar ABP 501 to adalimumab,” BioDrugs 30:339-351, 2016, and Barbeau et. al., “Application Note: Screening for inhibitors of TNFα/s TNFR1 Binding using AlphaScreen™ Technology,” PerkinElmer Technical Note ASC-016, 2002.

FIGS. 57A-57B illustrate the general principle of the assay. FIG. 57A shows binding of anti-TNFα to the TNFα receptor without drug, where uninhibited binding brings the Donor and Acceptor beads into close proximity for singlet oxygen transfer detection. FIG. 57B shows binding of anti-TNFα to TNFα that is inhibited by drug binding to TNFα, thus preventing binding to anti-TNFα antibodies and proximity oxygen singlet transfer detection.

Drug binding was detected using Luminescent Oxygen Channeling (LOCI™)—a competitive binding assay. Signal was detected by comparing to a non-drug carrier control and an artificially damaged drug using a commercial FAB fragmentation kit.

Drug function was determined through a competition binding assay comparing drug binding function for drug dispensed via standard delivery mechanism and drug delivered via the ingestible device with various pressures.

Results

The jet delivery pressures and nozzle dimensions utilized did not appear to affect the binding or function of the drug. Under the conditions evaluated in this experiment, the tested pressures did not significantly inhibit the ability of the drug to bind to the target TNFα as measured by the LOCI competitive inhibition assay. Table 41 shows the IC₅₀values of adalimumab binding to TNFα under the various conditions tested. FIG. 58A is a dose response curve generated after adalimumab (10,000 pg/mL) was dispensed into collection tubes under the conditions described in Table 40.

Any observable differences between the tested pressures and nozzle dimensions were within the standard deviation of the assay (FIG. 58B). The negative control (NC) sample curve was shifted to the right, demonstrating that damaged drug binds less to TNFα, allowing for an increase of singlet oxygen transfer due to the proximity of the Donor and Acceptor Beads.

Drug Structure

The purpose of this study was to evaluate the effects that nozzle geometry and delivery pressure have on drug structure when the drug is dispensed from a jet delivery device using different delivery pressures and nozzle sizes. Structural changes in the jet-delivered drug could potentially result in compromised functioning of the drug in vitro.

Test Method

The drug (adalimumab drug substance (DS)) was loaded into the simulated capsule jet delivery device and ejected using different pressures and nozzle geometries. Table 42 summarizes the samples and delivery conditions used.

The experimental design flow is shown in FIG. 59 and the assay principle is shown in FIG. 60. Briefly, OD280 nm readings were taken of pre- and post-dispensed samples, and pre- and post-papain digested adalimumab DS (whole IgG and Fab/Fc fragments, respectively) using a Cytation 5 plate reader and Take 3 micro-volume plate. The resulting protein concentrations were obtained using an extinction coefficient of 1.4 and Gen5 version 3.03.14 program. The samples were then diluted and the protein profiles were analyzed using non-reducing SDS-PAGE. Protein banding patterns of the dispensed samples were compared to that of the unmanipulated drug and the drug artificially damaged (enzymatically degraded) via the papain in a commercial Fab fragmentation kit (Pierce™ Fab Preparation Kit).

For gel analysis, protein was mixed with non-reducing sample buffer. Samples were not heated. 5 μg of samples and controls were loaded per lane of a SDS-PAGE gel (4% Acrylamide-Bis stacking, 12% resolving; see Table 43). The gel was electrophoresed at 195 V and stained in R-250 Coomassie Blue dye.

FIG. 61 shows the results of the gel analysis. All jet-delivered drug samples showed the same banding pattern as the unmanipulated drug. No subunit fragments were visible in their corresponding gel profiles, in comparison to intentionally degraded controls NC and Nc_gel. Banding for controls NC and Nc_geldiffered from each other. NC showed expected bands corresponding to Fab and Fc fragments (running at approx. 45-50 kda). Nc_gelshowed a lower MW band, likely due to further reduction of adalimumab (digested from a lower starting concentration than NC) to Fab heavy and light chain sub-components (approx. 25 kDa each). Undetermined fragments were also present (see column 8 of FIG. 61) as adalimumab was desalted, prior to its loading on the immobilized papain column.

No structural changes were evident and there was no physical indication that the drug had been inactivated through the dispensing pressures or nozzle sizes employed.

Example 9—Pharmacokinetic and Pharmacodynamic Assessment of Tofacitinib Citrate after Oral or Topical Intracecal Administration in a Dextran Sulfate Sodium (DSS)-Induced Colitis Mouse Model

Study Design

The overall study design is summarized in Table 45. 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.

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, TNFα, 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 timepoints and should be considered best estimates only.

All PK/PD concentrations are expressed as active drug moiety (anhydrous tofacitinib free base).

Pharmacokinetic Statistical Analysis

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: T_max; half-life: t_1/2, maximum concentration: C_max; 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 11/2012.

Results

Drug Tissue Concentrations

Animals dosed PO with tofacitinib citrate (Groups 3-4) demonstrated the highest mean plasma tofacitinib concentrations at all timepoints, while limited blood exposure was observed in animals treated IC (Groups 5-6) (See FIGS. 62A-62B). Plasma T_maxoccurred between 1.2 and 1.6 h post-dose in all groups, regardless of dosing route. Colon tissue T_maxoccurred between 1.43 and 1.86 h post-dose in all IC groups, and at 2.25 and 2.33 h post-dose in PO groups (Table 46). At similar dose levels, IC delivery of tofacitinib citrate (IC, 10 mg/kg) resulted in an 18-fold higher tofacitinib AUC colon tissue/plasma ratio when compared to PO delivery (PO, 15 mg/kg) (AUC ratio 193.76 vs. 10.6, respectively; Table 46). Plasma and tissue tofacitinib exposure (AUC_{0-24 h}) are also shown in FIGS. 63A-63C.

Cytokines

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).

FIGS. 64A-64B show results obtained for IL-6 in colon tissue on Day 12. IL-6 expression was induced by DSS treatment in both plasma (data not shown) and colon tissue (FIG. 64A) of PO and IC treatment groups; significant induction (p<0.05) was observed on Day 12 when compared with naïve animals (Group 1).

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 h and 24 h 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) (FIG. 64B). Recovery from IL-6 inhibition was observed in the low dose PO group (15 mg/kg) by 12 h post-dose.

The concentration of GM-CSF (a cytokine activated through stimulation of the JAK2/JAK2 pathway) 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).

Example 10—Topical Intracecal Administration of Therapeutic Antibodies in a Colitis Animal Model that has Previously Received an Adoptive T-Cell Transfer

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.

Materials

Test System

- Species/strain: Mice, C57Bl/6 (donors) and RAG2^−/− (recipients; C57Bl/6 background)
- Physiological state: Normal/immunodeficient
- Age/weight range at start of study: 6-8 weeks (20-24 g)
- Animal supplier: Taconic
- Randomization: Mice were randomized into seven groups of 15 mice each, and two groups of eight mice each.
- Justification: T cells isolated from male C57Bl/6 wild type donors were transferred into male RAG2^−/− recipient mice to induce colitis.

Animal Housing and Environment

- Housing: Mice were housed in groups of 8-15 animals per cage prior to cannulation surgery. After cannulation surgery, cannulated animals were single-housed for seven days post-surgery. After this point, animals were again group-housed as described above. Non-cannulated animals (Group 9) were housed at 8 mice per cage. ALPHA-Dri® bedding was used. Prior to colitis induction (i.e., during the cannulation surgeries), bedding was changed a minimum of once per week. After colitis induction, bedding was changed every two weeks, with ¼ of dirty cage material captured and transferred to the new cage. Additionally, bedding from Group 9 animals was used to supplement the bedding for all other groups at the time of cage change.
- Acclimation: Animals were acclimatized for a minimum of 7 days prior to study commencement. During this period, the animals were observed daily in order to reject animals that presented in poor condition.
- Environmental conditions: The study was performed in animal rooms provided with filtered air at a temperature of 70+/−5° F. and 50%+/−20% relative humidity. Animal rooms were set to maintain a minimum of 12 to 15 air changes per hour. The room was on an automatic timer for a light/dark cycle of 12 hours on and 12 hours off, with no twilight.
- Food/water and contaminants: Animals were maintained with Labdiet 5053 sterile rodent chow. Sterile water was provided ad libitum.

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 0.5×10⁶CD44/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 47, 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 47.

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 48). 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 CO₂inhalation 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.

Cecal Cannulation

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.

Disease Induction

Colitis was induced on Day 0 in male RAG2^−/− mice by IP injection (200 μL) of 0.5×10⁶CD44⁻/CD62L+ T cells (in PBS) isolated and purified from C57Bl/6 recipients.

Donor Cell Harvest

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.

Dosing

See Table 47.

Body Weight and Survival

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.

Animals Found Dead or Moribund

The animals were monitored on a daily basis and those exhibiting weight loss greater than 30% were euthanized, and did not have samples collected.

Endoscopy

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.

Sample Collection

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 in Colon Tissue

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).

Histopathology

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.

Statistical Analysis

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.).

Results

Survival

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.

Colon Weight:Length Ratio

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.

Disease Activity Index

The Disease Activity Index was determined in each mouse using a total score from the scoring system depicted in Table 48.

The data in FIG. 65 show that mice intracecally administered anti-TNFαL antibody (Group 8) had decreased disease activity index (DAI) as compared to mice intraperitoneally administered anti-TNFαL antibody (Group 7) at Day 42 of the study. The data in FIG. 67 show that mice intracecally administered anti-IL12 p40 antibody (Group 6) had decreased disease activity index (DAI) as compared to mice intraperitoneally administered anti-IL12 p40 antibody (Group 5) at Day 28 and Day 42 of the study.

Inflammatory Cytokines in Colonic Tissue

The concentration of inflammatory cytokines was evaluated in the colonic tissue in vehicle or IgG control groups.

A significant reduction of inflammatory cytokines, including TL 17A, IL-4, TNFα˜, and IL-22, were found in groups treated with anti-TNFαL (IC (Group 8) or IP (Group 7)) when compared with vehicle (IP/IC) control or its respective IgG controls (IC or TP) in colon tissue (FIG. 66). Mice treated with anti-TNFαL antibody IC (Group 8) had decreased levels of TNFα˜, IL-17A, and IL-4 in colonic tissue as compared to the levels in colonic tissue of mice treated with anti-TNFαL TP (Group 7) when assessed at Day 42 of the study.

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 (FIG. 68). Mice intracecally administered anti-IL12 p40 antibody (Group 6) had decreased levels of IFNγ, IL-6, IL-17A, TNFα, IL-22, and IL-1b in colonic tissue as compared to the levels in colonic tissue in vehicle-administered control mice (Group 2).

Body Weight Loss

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 FIGS. 69A and 69B. No apparent signs of disease were observed within the first week after induction of colitis. In control groups treated with PBS vehicle and/or IgG, BW loss did not begin until Days 14 through 16 and continued in the 3rd and 4th week following transfer during the acute phase. The weight loss was maintained until study termination on Day 42. Administration of anti-TNFα antibody or anti-IL12p40 antibody through either IP or IC had a significant reduction in AUC of the BW loss (%) from Day 0 to Day 42 along with the weight increase maintained from Day 21 to Day 42 (FIGS. 69A and 69B). Overall, intracecal administration of anti-IL12p40 antibody had the earliest recovery of weight loss and most significant reduction in overall BW loss from Day 0 Day 42 in comparison to the vehicle control group amount of all treatment groups (FIG. 69B).

Histopathology Colitis Score

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 (FIG. 70).

Lymphocyte Counts

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*, FIG. 69A). A similar trend in lymphocyte count reductions was found in the distal colon, although to a lesser degree. Results are shown in FIGS. 71A-71D. Mean counts and scores for all fields were generally the highest in vehicle-treated animals (Group 2, data not shown) and lower in those given anti-TNFα by IP (Group 7, data not shown) or IC (Group 8, FIG. 71). 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.

Example 11—Evaluation of the Bioavailability of Semaglutide after Intraduodenal Administration Via an Ingestible 2-Nozzle Jet Delivery Device in Female Yorkshire Pigs

A study was performed to determine the plasma pharmacokinetics of semaglutide in female Yorkshire pigs after intravenous (IV), subcutaneous (SC), or intraduodenal (ID) administration via an endoscopically placed ingestible device.

In Vivo Study Design

A total of 11 healthy female Yorkshire pigs (Sus scrofa domesticus) were used for the study: n=5 for ID administration, n=3 for IV administration, and n=3 for SC administration. Each pig weighed between about 25-30 kg at the initiation of the study. A fixed dose of 0.5 mg semaglutide per pig (˜0.02 mg/kg) was administered intraduodenally (ID) via the endoscopically placed ingestible device (Group 1); a 0.02 mg/kg dose was administered to each pig in the IV (Group 2) and SC (Group 3) dose groups. The study design is shown below in Table 49.

Semaglutide solution was administered at t=0 on the day of dosing. The animals were anesthetized with an intramuscular injection of a cocktail containing ketamine (approximately 10-20 mg/kg), xylazine (approximately 1-2 mg/kg) and atropine (approximately 0.02-0.04 mg/kg). The animals were intubated and maintained using isoflurane (approximately 3-5% in oxygen 1 to 4 L/min) as necessary until dosing was complete. The animals were wakened post dose.

Routes of Administration

For intravenous (IV) administration, the test article was administered intravenously via bolus dose into the marginal ear vein followed by a 1 mL flush with saline if necessary.

Sampling

Each blood sample (˜2.0 mL) were taken from the jugular vein (or other suitable vessel) of each pig via direct venipuncture. The samples were collected into chilled tubes with K2EDTA as the anticoagulant, and inverted several times to mix. Blood samples were kept on wet ice until centrifugation. The blood samples were centrifuged at a temperature of 4° C., at 3,000×g, for 5 minutes. All samples were maintained chilled throughout processing. Plasma was collected into pre-labeled 2-mL microcentrifuge tubes and placed in a freezer set to maintain a temperature of −60° C. to −80° C. until further analysis. The samples were taken prior to dosing, then again at 1, 3, 6, 8, 24, 72, 144, and 240 hours post-dose and sent to an off-site laboratory for bioanalytical analysis. Following the 240 hour post dose blood collection, the animals were euthanized via euthanasia solution IV bolus dose.

Analysis

Samples were processed and analyzed by using a modified LC-MS/MS method (Kapitza, C. et al., J. Clin. Pharm. (2015) 55(5) pp. 497-504) to quantify in swine plasma in the concentration range 5-500 (for BLQ samples) and 50-1000 ng/mL to quantify in swine plasma. Liraglutide was used as an internal standard (IS). The analysis was carried out using a Waters Xevo-TQ-S LC-MS/MS spectrometer monitoring positive ions in the MRM mode with mass transitions m z 1029.468>136.124 Da (semaglutide) and m z 938.9>1266.99 Da (IS), respectively. The LC system was a Waters Acquity™ UPLC® system and the LC column an InfinityLab Poroshell 120 Bonus-RP, 2.1×150 mm, 2.7 μm. Quantification was performed by peak areas and weighted linear regression (1/x²). The lower limit of quantification (LLOQ) for semaglutide was 5 ng/mL. All data and pharmacokinetic parameters were analyzed and graphed using GraphPad Prism version 7.00 for Windows, (GraphPad Software, La Jolla Calif. USA). The area under the concentration curve (AUC) versus time was calculated with the trapezoidal rules from the first sample collection time points (pre-dose, time 0) to last time point of sample collection (240 h post-dose) ((AUC)_T0-T240h)). Non-compartmental analysis was used to determine PK parameters for each subject. AUC_T0-T240h, C_maxand T_maxwere determined for each subject. The bioavailability of semaglutide via ID administration (Group 1) in comparison to the IV (Group 2) and SC (Group 3) administrations was determined.

Results

The results of the study are shown in Table 50 and in FIGS. 72A-72C show the semaglutide concentration in blood over time after: ID administration via the endoscopically placed ingestible device (FIG. 72A); IV administration (FIG. 72B3); and SC administration (FIG. 72C).

The bioavailability of semaglutide via TD administration was determined relative to IV or SC administration. The results are shown in Table 50.

Example 12—Evaluation of the Bioavailability of Adalimumab after Intraduodenal Administration Via Endoscopic Needle Injection in Female Yorkshire Pigs

Two studies were conducted to evaluate the plasma pharmacokinetics of adalimumab in female Yorkshire pigs after intraduodenal (ID) administration via an endoscopic injection needle. The results were compared with those obtained after administration of adalimumab via a 2-nozzle jet delivery device, SC or IV (Example 5).

Test Article

Adalimumab in an aqueous buffer having an adalimumab concentration of about 100 mg/mL.

In Vivo Study Design

A total of 5 healthy female Yorkshire pigs (Sus scrofa domesticus) having a body weight of ˜25-40 kg were used in these studies, 3 in a first study and 2 in a second study. Each animal received test article via intraduodenal (ID) administration via an injection needle. The study design is shown below in Table 51.

Animals were housed one per cage and fasted for a minimum of 12 hours prior to dosing. Food was returned at 4 hours post-dose. Water was supplied ad libitum.

Intraduodenal (ID) administration was performed as follows. The endoscope (Olympus OSF-V60 attached to an Olympus CV60 Tower) configured with an endoscopic injection needle was maneuvered into the pyloric sphincter with camera visualization to identify the third (inferior/horizontal) part of the duodenum (D3). Following confirmation of placement of the endoscopic injection needle in the correct region, the endoscope was retracted out of the pyloric sphincter, leaving the injection device in the D3 region of the duodenum. Once it was confirmed that the endoscopic injection needle was placed in the correct region, approximately 0.5 mL of saline was injected within the lamina propria of the mucosa to create a small bleb in the mucosa. The formulation was then injected into the bleb and flushed with approximately 0.8 mL of saline. The animals were kept under anesthesia through the 1 hour blood collection time point. All other blood collections were performed on the pigs without the use of anesthesia.

Sampling

Plasma samples were collected at pre-dose, 1, 3, 6, 8, 24, 72, 144, and 240 hours post-dose in all animals and sent to an off-site laboratory for bioanalytical analysis. Samples were processed and analyzed by using an adalimumab (anti-TNF-alpha) ELISA kit from Alpha Diagnostics, Inc. (Catalog #200 310-AHG). All plasma samples were diluted by 1:100 dilution. Diluted samples were processed in duplicates and the mean Optical Density (O.D.) was measured using a SpectraMax plate reader and utilizing SoftMax Pro software for analysis. The Lower Limit of Quantification (LLOQ) was calculated by adding 10× the standard deviation value of the blanks O.D. to the average of the blank standard O.D. values. Mean concentrations of adalimumab were back interpolated to a 4-parameter log fit standard curve and subsequently multiplied by the dilution factor to obtain a final corrected adalimumab concentration. All data and pharmacokinetic parameters were analyzed and graphed by using GraphPad Prism version 7.00 for Windows, GraphPad Software, La Jolla Calif. USA, www.graphpad.com (GraphPad Prism 7). The area under the concentration curve (AUC) was calculated with the trapezoidal rules.

Results

PK analysis showed that one animal from the first study and one animal from the second study had quantifiable levels of adalimumab in plasma. The mean (AUC)_T0-T240hfor these two animals was determined and the results are shown in FIG. 73 in comparison with subset of data from Example 5, specifically, Example 5 Group 3 (ID administration via ingestible jet delivery device having an internal pressure of 320 psig), Group 4 (SC) and Group 5 (IV).

Example 13—Workflow for Clinical Trial

The following workflow can be used in clinical trials testing the ingestible device 100 described above:

1. Capsule is pre-assembled with a target dispensing location identified.

2. Subject is briefed on device functionality and provides informed consent.

3. Capsule is pre-loaded with a quantified amount of therapeutic drug.

4. Capsule is pressurized (drive mechanism).

5. Capsule is shipped to the clinical site.

6. Subject arrives at clinical site fasted.

7. Site personnel ensures that subject swallows the capsule under medical supervision.

8. Capsule completes delivery of drug at pre-determined dispensing location.

9. Capsule naturally passes through GI tract and is excreted.

Other Embodiments

While certain embodiments have been provided, other embodiments are possible.

As an example, some embodiments have been described in which an ingestible device includes one or more pins. However, the disclosure is not limited in this sense. Rather, in such embodiments, any element having the appropriate shape and size, as well as being made of the appropriate material(s), may be used instead of (or, in some cases, in addition to) one or more of the pins.

As another example, while embodiments have been described in which the dispensable substance is released in a single stage. Other embodiments are possible. In some embodiments, multi-stage (e.g., two stage, three stage, four stage) release of the dispensable substance is used. Multi-staged release can be achieved, for example, via multiple elements (e.g., pins, plugs or the like) formed of different materials (e.g., different enteric materials) that degrade/dissolve erode under different conditions (e.g., different pH, temperature, enzyme concentration) present in different locations in the GI tract of a subject.

As an additional example, while embodiments have been described in which an ingestible device includes a seal or a coating, the disclosure is not limited in this sense. For example, in some embodiments, an ingestible device housing may be covered in one or more coverings, e.g., to seal the ingestible device and/or to hold two modules of the device together. In certain embodiments, an ingestible device may be sealed to prevent contaminants from entering the ingestible device prior to administration to a subject (e.g., during storage of the device) or after administration to a subject (e.g., during transit through the stomach), or to prevent the contents of the ingestible device (e.g., a dispensable substance) from exiting the ingestible device before desired (e.g., prior to triggering). In certain embodiments, an ingestible device is assembled from two modules: one module contains the dispensable substance (“drug module”), while the other module contains the drive force generator and the drive coupling (“drive module”). One or more coverings can be used to partially or wholly join and/or seal the two modules after they are assembled together to form an ingestible device. In some embodiments, one or more coverings cover the entirety of the housing of the ingestible device, while in other embodiments one or more coverings cover only a portion of the housing the ingestible device (e.g., parts of the housing with an opening, parts of the housing that comprise enteric materials, or parts of the housing assembled from two or more different modules after the modules are joined together to form an ingestible device). Examples of covering materials include foils, films, and other materials that degrade or erode in the GI tract, and/or that are made of a relatively low mechanical strength material (e.g., so that a dispensable substance can pass through the covering and exit in the form of a jet after triggering). In some embodiments, one or more coverings are made of a gelatin material, for example, using a gel-enrobed technology such as Press-Fit® or XPress-Fit® gel cap from Lonza (see, e.g., U.S. Pat. Nos. 5,317,849, 5,460,824, 5,464,631, 5,511,361, 5,795,588, 5,609,010, 6,080,426, and 6,245,350). In some embodiments, the one or more coverings are applied to the device housing using a cold-shrink process. In some embodiments, the one or more coverings degrade or erode in the stomach or in the proximal small intestine (e.g., in the duodenum).

As a further example, while certain embodiments of an ingestible device have been described in relation to certain forms of delivery (trans-epithelial, epithelial, topical), the disclosure is not limited in this sense. As an example, in some embodiments, a device described for use in trans-epithelial delivery or for use in epithelial delivery can be used in topical delivery. Generally, such embodiments involve modifying the relevant parameters (e.g., internal pressure, fluid pressure) accordingly. As another example, in some embodiments, a device described for use in epithelial delivery or for use in epithelial delivery can be used in topical delivery. Generally, such embodiments involve modifying the relevant parameters (e.g., internal pressure, fluid pressure) accordingly.

As an additional example, in some embodiments, the volume of the pharmaceutical formulation deposited in the submucosa and/or the mucosa (e.g., into the lamina propria) is about 1 microliter to about 800 microliters, about 10 microliters to about 800 microliters, about 50 microliters to about 800 microliters, about 100 microliters to about 800 microliters, about 200 microliters to about 800 microliters, about 300 microliters to about 800 microliters, about 400 microliters to about 800 microliters, about 500 microliters to about 800 microliters, about 600 microliters to about 800 microliters, about 700 microliters to about 800 microliters, about 1 microliter to about 700 microliters, about 10 microliters to about 700 microliters, about 50 microliters to about 700 microliters, about 100 microliters to about 700 microliters, about 200 microliters to about 700 microliters, about 300 microliters to about 700 microliters, about 400 microliters to about 700 microliters, about 400 microliters to about 700 microliters, about 500 microliters to about 700 microliters, about 600 microliters to about 700 microliters, about 1 microliter to about 600 microliters, about 10 microliters to about 600 microliters, about 50 microliters to about 600 microliters, about 100 microliters to about 600 microliters, about 200 microliters to about 600 microliters, about 300 microliters to about 600 microliters, about 400 microliters to about 600 microliters, about 400 microliters to about 600 microliters, about 500 microliters to about 600 microliters, about 1 microliter to about 500 microliters, about 10 microliters to about 500 microliters, about 50 microliters to about 500 microliters, about 100 microliters to about 500 microliters, about 200 microliters to about 500 microliters, about 300 microliters to about 500 microliters, about 400 microliters to about 500 microliters, about 1 microliter to about 400 microliters, about 10 microliters to about 400 microliters, about 50 microliters to about 400 microliters, about 100 microliters to about 400 microliters, about 200 microliters to about 400 microliters, or about 300 microliters to about 400 microliters. In some embodiments, the volume of the pharmaceutical formulation deposited in the submucosa and/or the mucosa (e.g., into the lamina propria) is about 1 microliter to about 500 microliters, about 10 microliters to about 400 microliters, about 50 microliters to about 400 microliters, about 100 microliters to about 400 microliters, about 200 microliters to about 400 microliters, 250 microliters to about 400 microliters, or about 300 microliters to about 400 microliters. In some embodiments, the volume represents the total volume delivered by the one or more jets. In some embodiments, the volume represents the total volume delivered (or released from the ingestible device) via one jet, by two jets, by three jets, by four jets, or by five jets. In some embodiments, the volume represents the total volume of the pharmaceutical formulation delivered by two jets. For example, when the volume of the pharmaceutical formulation is about 400 microliters, and when the device has two nozzles, the volume of pharmaceutical formulation delivered by each jet is about 200 microliters.

As a further example, in some embodiments, the formulation is deposited in the submucosa and/or the mucosa (e.g., into the lamina propria) of the small intestine of the subject. In some embodiments, the formulation is deposited in the submucosa and/or the mucosa (e.g., into the lamina propria) of the duodenum of the subject. In some embodiments, the formulation is deposited in the submucosa and/or the mucosa (e.g., into the lamina propria) of the jejunum of the subject. In some embodiments, the formulation is deposited in the submucosa and/or the mucosa (e.g., into the lamina propria) of the ileum of the subject.

As another example, in some embodiments, the volume of the pharmaceutical formulation deposited in the mucosa is about 1 microliter to about 800 microliters, about 10 microliters to about 800 microliters, about 50 microliters to about 800 microliters, about 100 microliters to about 800 microliters, about 200 microliters to about 800 microliters, about 300 microliters to about 800 microliters, about 400 microliters to about 800 microliters, about 500 microliters to about 800 microliters, about 600 microliters to about 800 microliters, about 700 microliters to about 800 microliters, about 1 microliter to about 700 microliters, about 10 microliters to about 700 microliters, about 50 microliters to about 700 microliters, about 100 microliters to about 700 microliters, about 200 microliters to about 700 microliters, about 300 microliters to about 700 microliters, about 400 microliters to about 700 microliters, about 400 microliters to about 700 microliters, about 500 microliters to about 700 microliters, about 600 microliters to about 700 microliters, about 1 microliter to about 600 microliters, about 10 microliters to about 600 microliters, about 50 microliters to about 600 microliters, about 100 microliters to about 600 microliters, about 200 microliters to about 600 microliters, about 300 microliters to about 600 microliters, about 400 microliters to about 600 microliters, about 400 microliters to about 600 microliters, about 500 microliters to about 600 microliters, about 1 microliter to about 500 microliters, about 10 microliters to about 500 microliters, about 50 microliters to about 500 microliters, about 100 microliters to about 500 microliters, about 200 microliters to about 500 microliters, about 300 microliters to about 500 microliters, about 400 microliters to about 500 microliters, about 1 microliter to about 400 microliters, about 10 microliters to about 400 microliters, about 50 microliters to about 400 microliters, about 100 microliters to about 400 microliters, about 200 microliters to about 400 microliters, or about 300 microliters to about 400 microliters.
