The present disclosure relates generally to compositions, dosage forms, devices, and methods for delivery of anti-interleukin antibodies such as ustekinumab by ingestion. More specifically, the present disclosure relates to ingestible dosage forms (e.g., ingestible devices) that contain a composition comprising anti-interleukin antibodies such as ustekinumab that are structured and formulated to deliver therapeutically effective amounts of anti-interleukin antibody into a gastrointestinal (GI) lumen wall (e.g., stomach wall, intestinal wall, colon, etc.) of the subject or into and through a GI lumen wall into a peritoneum or peritoneal cavity of the subject (and thereafter into the bloodstream) to achieve desired pharmacokinetic and therapeutic results. The compositions, devices, and methods may be useful, for example, for the treatment of psoriasis (including moderate to severe plaque psoriasis), psoriatic arthritis, Crohn's disease (including moderate to severe Crohn's disease), ulcerative colitis (including moderate to severe ulcerative colitis), and other conditions in which treatment with an anti-interleukin antibody may be indicated.
The following discussion is merely provided to aid the reader in understanding the disclosure and is not admitted to describe or constitute prior art thereto.
The anti-interleukin antibody product STELARA® (ustekinumab) currently is approved for use in the U.S. for the treatment of moderate to severe plaque psoriasis, psoriatic arthritis, moderate to severe Crohn's disease, and moderate to severe ulcerative colitis. STELARA® is administered by subcutaneous or intravenous injection. The dosing regimen for patients weighing up to 100 kg is 45 mg administered subcutaneously initially and 4 weeks later, followed by 45 mg administered subcutaneously every 12 weeks. The dosing regimen for patients weighing over 100 kg is 90 mg administered subcutaneously initially and 4 weeks later, followed by 90 mg administered subcutaneously every 12 weeks.
Shaped masses comprising biologically active proteins or polypeptides, including anti-interleukin antibodies, have been described, for example, in U.S. Pat. Nos. 10,098,931 and 10,227,403. Other anti-interleukin antibody preparations are described in U.S. Pre-Grant Publication 2018/0251537.

Disclosed herein are ingestible dosage forms (ingestible devices) useful for delivering anti-interleukin antibodies to a subject in need thereof. The devices contain a payload formed from, or containing, a composition comprising anti-interleukin antibodies, and are structured to deliver the composition into a GI lumen wall of the subject or into and through a GI lumen wall into, e.g., a peritoneum or peritoneal cavity of the subject, after ingestion. As noted above, the anti-interleukin antibodies provided in the devices may bind to one or both of human interleukin-23 and human interleukin-12 and/or may be antagonists of one or both of human interleukin-23 and human interleukin-12. As noted above, the anti-interleukin antibodies provided in the devices may be or comprise ustekinumab or a biosimilar thereof. Although the anti-interleukin antibodies provided in the devices are not limited to ustekinumab, for the sake of convenience the discussion that follows refers to ustekinumab. It should be understood that other anti-interleukin antibodies could be used in addition to or instead of ustekinumab, including antibodies that are biosimilar to ustekinumab, and/or other antibodies that bind to one or both of human interleukin-23 and human interleukin-12 and/or may be antagonists of one or both of human interleukin-23 and human interleukin-12.
As noted above, the ingestible dosage forms described herein are ingestible devices that contain a payload made from or comprising or containing a composition including ustekinumab. The payload may be in the form of a solid tissue penetrating member structured to penetrate a GI lumen wall of the subject and be inserted into the GI lumen wall or surrounding bodily environment (e.g., peritoneum or peritoneal cavity) of the subject after ingestion of the device (e.g., after swallowing the device or after ingestion of the device by another mode, such as via an endoscope or stomach port), thereby delivering the ustekinumab into the blood stream of the subject. The payload may be formed from, or may contain, the composition. Specific embodiments of such devices are described in more detail below. Any devices disclosed or referenced herein optionally may be disposed within a capsule, such as a swallowable capsule. Typically, the materials used to form the components of the devices are classified as food grade, food additive, active or inactive food ingredient or GRAS (Generally Recognized As Safe by the FDA). The devices (including any capsule shell) may be biodegradable.
Thus, in some embodiments, the capsule and/or the coating are designed to degrade in the presence of a particular chemical, or after a certain length of time under the conditions expected at a target site within the GI tract (e.g., under certain values or ranges of pH, temperature, pressure exerted against the capsule, or a combination of the foregoing). In an embodiment, the coating includes a material to improve swallowability and/or ingestibility, such as guar gum or xanthan gum.
The device may contain a mechanism to effectuate delivery of the payload into a location of the GI tract, such as the intestinal wall or into and through an intestinal wall into, e.g., a peritoneum or peritoneal cavity of the subject. In an embodiment, the mechanism includes an actuator that is triggered when the device is at a target delivery site, such as within the intestine. In other embodiments, the mechanism may effectuate delivery of the payload at another location in the GI tract, such as the stomach, large intestine, or colon.
In the embodiment of
In general, the mechanism to effectuate delivery of the payload into the intestinal wall may include various mechanical, electrical, electromechanical, and/or chemical components. For example, springs, levers, and/or various movable components may together constitute the mechanism.
The payload may be disposed within a protective enclosure until just before (e.g., in terms of ms or ps) the payload is delivered into the intestinal wall. For example, in the embodiment of
After entering the intestinal wall or surrounding bodily environment (e.g., peritoneum or peritoneal cavity), the payload dissolves or degrades in the moist tissue environment to release the ustekinumab composition into the blood stream.
The payload may be a hollow structure in which the ustekinumab composition is disposed, or the payload may itself be formed from the ustekinumab composition (e.g., the ustekinumab composition may be compressed into a desired size and shape). In an embodiment, the ustekinumab composition is compressed into a cylindrically-shaped microtablet or other shaped microtablet. In an embodiment, the ustekinumab composition (in uncompressed or compressed form) is disposed within a degradable shell, and the shell containing the microtablet is the payload. In an embodiment, the shell is approximately needle-shaped. Degradation of the payload may occur within 1, 2, 3, 4, or 5 minutes of injection into the intestinal wall, or may take longer. Properties of the payload (e.g., structure and/or material) may be selected to delay release of the ustekinumab from the payload.
The device may include a detectable marker, such as a radiolabel, to assist in tracking the device as it proceeds through the subject's GI tract. Examples of markers include, but are not limited to, barium sulfate (whose dispersion indicates fluid ingress inside the device and imminent delivery of the payload) and bismuth, which optionally may be included on or in a component contained in the device to radiographically track the component's transit along the GI tract as well as to confirm its excretion.
In an embodiment, which may be similar to the embodiment illustrated in
In some embodiments, the expandable component includes multiple sections. In the expanded configuration of the expandable component, at least one of the sections is non-compliant and at least one of the sections is compliant. Compliant refers to a state in which the section may be readily deformed, and non-compliant refers to a state in which the section resists deformation. Absent a constraint, each section will expand to a fully-extended state and the expandable component will reach its maximum dimensions, which may depend, for example, on materials used to form the expandable component and/or a capacity of an expansion module that is implemented (e.g., for expansion by inflation, maximum dimensions may be influenced by a limitation on an inflation force available from the expansion module, or by a stretch factor of a material or materials of the expandable component). The expansion module is part of a mechanism to effectuate delivery of the payload into the intestinal wall.
Each compliant section operates in a similar fashion to a hinge and thus will be referred to for convenience as a hinge. In a fully-extended state of the expandable component (where each section is fully extended), each hinge has at least one design dimension (width, length, and/or circumference) that is substantially smaller than a corresponding design dimension of each non-compliant section.
As the expandable component expands, it will achieve a shape that reflects an equilibrium between a force exerted by the expandable component on an interior of a lumen of the GI tract and a force of the lumen against the expandable component. Said another way, the expandable component may not fully extend and will tend to be bent about the hinge if constrained by the lumen. This bending is due to the smaller dimension(s) of the hinge as compared to the corresponding dimension(s) of the non-compliant section(s), which in the expanded configuration of the expandable component leads to lower rigidity of the hinge as compared to rigidity of the non-compliant section(s).
In this way, the expandable component expands until the non-compliant sections (which may hereinafter be referred to as NCS) are pressed against the lumen inner wall to maintain the expandable component in a position suitable for delivering a ustekinumab composition to the lumen wall, for a time at least sufficient to accomplish such delivery. The expandable component may then be deflated.
The expandable component may be removed after deflation, may be left to degrade in situ, or may be allowed to pass out of the lumen. The expandable component can be structured from degradable materials such that the expandable component degrades after a designed period of time after exposure to an environment at a target site.
A self-sizing device as described above may be used to deliver a therapeutic ustekinumab composition into a GI lumen wall (e.g., stomach wall, intestinal wall, colon) via ingestion (e.g., swallowing or other mode of ingestion). The self-sizing device may include a capsule. The self-sizing device may include a coating on the capsule and/or on the expandable component (e.g., a coating as described above), designed to degrade at a particular location within the GI tract, such as within the intestine. In an embodiment, all or portions of the capsule and/or the coating are designed to degrade in the presence of a particular chemical, or after a certain length of time under the conditions expected at a target site within the GI tract (e.g., under certain values or ranges of pH, temperature, pressure exerted against the capsule, or a combination of the foregoing). In an embodiment, the coating includes a material to improve swallowability and/or ingestibility, such as guar gum or xanthan gum.
Expansion of an expandable component may be accomplished by any suitable expansion module. In an embodiment, a spring mechanism is released from a compressed state to deploy, for example, a filler piece of firm or soft material to push outwards and thus expand the expandable component. In an embodiment, two or more reactants are mixed together to form a gas and thus expand the expandable component. In an embodiment, a material is rapidly combusted to generate a gas and thus expand the expandable component. Other expansion modules are within the scope of the present disclosure.
Expandable component 1250 may be expanded by generation of gas, and may include a valve 1255 to release the gas from within expandable component 1250 into lumen 1200 to deflate expandable component 1250. Valve 1255 may include one or more components. In an embodiment, valve 1255 is a pinch valve that degrades in the presence of fluid (e.g., biological matter) to reveal a port or an opening defined by expandable component 1250. In an embodiment, valve 1255 is a piece of material or a coating over a port or an opening in expandable component 1250, and the piece of material or coating is designed to degrade a period of time after expandable component 1250 delivers a therapeutic ustekinumab composition. In an embodiment, valve 1255 is opened manually.
The therapeutic composition of ustekinumab (or multiple therapeutic compositions) can be stored within expandable component 1250 in any constitution (e.g., as a solid, fluid, slurry, or powder). The therapeutic composition(s) can be delivered in any constitution (e.g., as a solid, fluid, slurry, or powder). In some embodiments, two or more components of the therapeutic composition are mixed within expandable component 1250 prior to delivery. In an embodiment, expandable component 1250 includes a portal such as portal 1260 defining an opening 1261 through which the therapeutic composition is delivered. In embodiments that include a tissue penetrating member, the tissue penetrating member may be delivered through the portal.
The therapeutic ustekinumab composition is actively released such that the therapeutic ustekinumab composition is forcibly expelled from expandable component 1250 and into lumen 1200 or beyond the lumen wall into the surrounding bodily environment (e.g., through the mucosa, submucosa, muscularis, serosa, outer wall of lumen 1200, and into the peritoneal cavity); in such an embodiment, the therapeutic ustekinumab composition may be released through one or more portals such as portal 1260.
The therapeutic composition of ustekinumab may be forcibly expelled from expandable component 1250 by a delivery mechanism. For example, with respect to a solid composition (e.g., tablet, pellet, or pointed form), the therapeutic ustekinumab composition may be expelled by way of a spring mechanism that is released to quickly eject the solid composition out of expandable component 1250, or by way of a piston mechanism in which the piston is moved by a spring mechanism, or a gas expansion to push the solid composition quickly out of expandable component 1250.
With respect to a fluidic composition (e.g., a liquid), the therapeutic ustekinumab composition may be expelled as a fluid jet by way of a spring mechanism or gas acting on a piston or plunger to eject the preparation from a reservoir through an opening or nozzle of expandable component 1250. The fluid jet of the therapeutic ustekinumab composition can have sufficient force to actively penetrate the GI lumen wall and enter the blood stream.
Additionally or alternatively, the fluidic composition including ustekinumab may be expelled through a hollow needle coupled to expandable component 1250. The hollow needle can penetrate into and/or through the GI lumen wall by way of a spring mechanism or gas acting on a piston or plunger to eject the composition through the needle and into the GI lumen wall or surrounding tissue thereof.
In some embodiments, a surface of expandable component 1250 through which the therapeutic ustekinumab composition is delivered contacts the wall of lumen 1200 along a stretch of approximately 5 mm to 20 mm.
In some embodiments, the therapeutic ustekinumab composition is delivered from expandable component 1250 from multiple surfaces. Such embodiments may include more than one tissue penetrating member that is formed from or contains a ustekinumab composition.
Multiple devices 1300 (
Specific materials can be chosen to confer desired structural and material properties to the payload (e.g., column strength for insertion into the lumen wall, or porosity and/or hydrophilicity for controlling disintegration of the payload and thus the release of a therapeutic ustekinumab composition). For example, certain materials may be more suitable when the payload is formed as a tissue penetrating member, whereas other materials may be more suitable when the payload is contained within a tissue penetrating member. In an embodiment, a tip of the payload includes or is coated with a degradable material such as sucrose, maltose, or other sugar, to increase hardness and tissue piercing properties of the tip. Once positioned within a lumen wall, the payload may be degraded by interstitial fluids within tissue so that the therapeutic ustekinumab composition dissolves and is absorbed into the blood stream. Properties of a payload such as size, shape, and chemical composition can be selected to allow for dissolution and absorption of a drug in a matter of seconds, minutes, or hours. Rates of dissolution can be controlled through various excipients such as disintegrants (e.g., starch, sodium starch glycolate, or a cross-linked polymer such as carboxymethyl cellulose). The choice of disintegrants may be specifically adjusted for the environment within a lumen wall (e.g., blood flow and average number of peristaltic contractions).
A payload can be fabricated entirely from a ustekinumab composition, or can define a cavity that includes a ustekinumab composition. A self-sizing device can include and deliver one or more payloads, each of which can contain the same or a different ustekinumab composition. Each payload can have different properties; for example, two payloads may be designed to deliver respective compositions concurrently (e.g., two instances of one composition, or one instance each of two distinct compositions), or may be designed to deliver respective compositions at different times (e.g., to provide a subsequent dose of a same ustekinumab composition or to provide a different ustekinumab composition subsequently).
Various embodiments of microtablets comprising a ustekinumab composition in the form of solid shaped masses comprising ustekinumab and methods for forming such solid shaped masses are described. A shaped mass may comprise a therapeutic composition that comprises a drug (e.g., ustekinumab) and one or more pharmaceutically acceptable excipients, including degradable material (such as a sugar, polyethylene, lactic acid polymer, poly(glutamic acid-co-lactic acid-co-glycolic acid (PGLG), etc.) which degrades within a target delivery site in the body (e.g., the wall of the small intestine or peritoneum or peritoneal cavity) to release drug.
The shaped mass can be formed from a variety of shaping processes known in the pharmaceutical arts. Typically, the shaped mass will be formed by a compression process such as compression molding. According to one or more embodiments, the biological activity of the ustekinumab in the shaped mass is at least about 70% of that prior to compression, at least 80% of that prior to compression, at least 85% of that prior to compression, about 90% of that prior to compression, or at least 95% of that prior to compression.
The shaped mass can have a density in a range from about 0.60 mg/mm3 to about 1.15 mg/mm3, from about 0.70 mg/mm3 to about 1.15 mg/mm3, from about 0.80 mg/mm3 to about 1.10 mg/mm3, from about 1.02 to 1.06 mg/mm3, or from about 1.03 to 1.05 mg/mm3.
The shape of the shaped mass may be any shape suitable for use as a component of a device as described herein, e.g., any shape suitable for disposing within a tissue-penetrating member (e.g., a pellet or cylindrical shape) or any shape suitable for use as a tissue-penetrating member (e.g., a needle or dart shape). The shaped mass may comprise a pellet shape, or may have a tablet, conical, pyramidal, hot dog/capsule like, arrow head, cylindrical, cube, sphere, hemisphere or other suitable shape. For embodiments of the shaped mass having a cylindrical or pellet shape, the shaped mass may have a diameter in the range from about 0.5 mm to 1 mm and a length from about 1.75 mm to 3.25 mm.
As noted above, according to various embodiments, the shaped mass can be formed in part from a degradable material that is configured to dissolve or otherwise degrade, e.g., in the wall of the intestine or in the peritoneum or peritoneal cavity, so as to release the drug for systemic absorption. Suitable degradable materials include various sugars such as trehalose, maltose and sucrose, various lactic acids polymers such as polyglycolic acid (PGA), polylactic acid (PLA); polyglycolic lactic acid (PGLA); poly(glutamic acid-co-lactic acid-co-glycolic acid (PGLG); various polyethylenes such as high density, low density and linear low density PE and PEO (polyethylene oxide), various cellulose polymers such as HPMC (hydroxypropyl methyl cellulose), CMC (carboxy methyl cellulose), MC (methyl cellulose), methacrylic acid-ethyl acrylate copolymer, methacrylic acid-methyl methacrylate copolymer PVOH (polyvinyl alcohol), silicone rubber. and other biodegradable polymers known in the art. The material and other properties of the degradable polymer and shaped mass can be selected to produce selectable rates of degradation in the intestinal wall or other target delivery site (e.g., peritoneum or peritoneal cavity).

The selection and proportions of the different ingredients may be taken into consideration during the formulation process so as to achieve a desired therapeutic dose of the drug with desired properties including desired tabletting properties, and desired release properties from the resulting microtablet.
The composition obtained as described above may be milled to produce a fine powder. For example, the composition may be placed in a low-protein-binding tube along with a single high-density milling ball, such as one made of stainless steel or yttrium-stabilized zirconium. The milling may be done using a rotator at max speed containing the tube film-wrapped to avoid moisture absorption or contamination. An ice pack may be placed on top of the tube to keep it cold. The room temperature can be controlled in a range for example from 60 to 64° F. The size of the milling tube, mass of the milling ball and duration of mixing may be selected to produce particular powder grain sizes, grain size homogeneity and powder density. For example, for the production of a 40 mg to 100 mg batch capacity, the use of a bottom-rounded 2 mL tube, a milling ball having a 0.44 g mass and a milling duration of 3 hours have resulted in fine and consistent grain sizes, achieving homogeneous and reliable density values.
The microtablet formation process is typically done via compression using a compression mold or other fixture to apply a compressive force to the fine powder including the drug (e.g., ustekinumab). A semiautomatic or fully automatic compression fixture may be used, as described in U.S. Pat. No. 10,098,931, the entire contents of which are incorporated herein by reference. As noted above, in various embodiments, the shaped mass can be formed into the shape of a tissue-penetrating member, i.e. it can be formed to have a tissue-penetrating shape by using molding or other like methods. In these and related embodiments, the shaped mass can have a needle or a dart-like shape (with or without barbs) configured to penetrate and/or be retained in to a tissue, or a membrane such as the intestinal wall.
After the microtablet is fabricated, the length, weight, density and bioactivity of the drug in the pellet may be measured. The bioactivity of the drug in the microtablet may be assayed using an enzyme-linked immunosorbant assay (ELISA) or other immune assay known in the art.
As described above, the shaped mass can be in the form of a tissue-penetrating member (e.g. in the form of a dart or needle) or contained in a tissue-penetrating member that is configured to be advanced into an intestinal wall or into and through an intestinal wall into a peritoneum or peritoneal cavity and biodegrade to release the ustekinumab in the intestinal wall, peritoneum or or peritoneal cavity and then the bloodstream.

Currently approved anti-interleukin antibody products such as STELARA® (ustekinumab) require administration by subcutaneous or intravenous injection, which can be inconvenient and uncomfortable for patients. The present disclosure addresses this limitation by providing a route of administration that effectively delivers anti-interleukin antibodies into the bloodstream of a subject being treated without requiring injection, such as oral administration or ingestion by another mode, such as via an endoscope or stomach port. The disclosed treatments are more convenient and less invasive than currently approved anti-interleukin antibody products.
In addition to improved ease of administration, patient comfort, and patient compliance, administration of ustekinumab via an ingestible device as described herein may offer one or more other advantages, such as one or more of enhanced bioavailability and reduced immunogenicity as compared to another route of administration, such as subcutaneous injection. In some embodiments, ustekinumab administered via an ingestible device as described herein exhibits a bioavailability that is greater than a bioavailability of subcutaneously administered ustekinumab.
In some embodiments, ustekinumab administered via an ingestible device as described herein exhibits a bioavailability that is substantially the same as a bioavailability of subcutaneously administered ustekinumab.
Thus, in accordance with some aspects, the present disclosure provides methods of administering anti-interleukin antibodies (such as ustekinumab or a biosimilar thereof, or other anti-interleukin antibodies that bind to or are antagonists of one or both of human interleukin-23 and human interleukin-12) to a subject in need thereof, comprising administering to the subject by ingestion an ingestible device containing a payload formed from, or containing, a composition comprising the anti-interleukin antibodies, wherein the device is structured to deliver the composition into an intestinal wall of the subject or into and through an intestinal wall into a peritoneum or peritoneal cavity of the subject, after ingestion. As noted above, the administration may comprise oral administration (e.g., swallowing the device) or ingestion of the device by another mode, such as via an endoscope or stomach port. The payload may be in the form of a solid tissue penetrating member structured to penetrate an intestinal wall of the subject and be inserted into intestinal wall or into and through the intestinal wall into a peritoneum or peritoneal cavity of the subject after ingestion of the device. The administration of such ingestible devices may be repeated, for example, at a frequency of once every 1-3 days or less frequently, such as in accordance with any of the dosing regimens described above. The payload may be formed from, or may contain, the composition including anti-interleukin antibodies, such as a solid (dry) composition or liquid composition as described above. The payload is protected from the gastrointestinal (GI) tract environment (e.g., protected against degradation due to ingress of fluid reaching the payload) until the payload is injected into the wall of the small intestine, which is insensitive to sharp stimuli so that the subject does not register pain from the injection.
The present disclosure also provides methods of treating one or more conditions such as psoriasis (including moderate to severe plaque psoriasis), psoriatic arthritis, Crohn's disease (including moderate to severe Crohn's disease), ulcerative colitis (including moderate to severe ulcerative colitis), and other conditions in which treatment with an anti-interleukin antibody may be indicated, comprising administering by ingestion to a subject in need thereof an ingestible device as described herein, such as in accordance with any of the dosing regimens described above.
