Dosage forms of oral drugs for release in the colon and methods of use and manufacture thereof. TECHNICAL FIELD
[0001] The present invention, in some aspects, relates to oral drug dosage forms configured to release a drug at a desired location in the colon of an individual. In other aspects, the present invention relates to methods for designing, methods for manufacturing, such as the use of three-dimensional printing, and treatment methods associated with the oral drug dosage forms described in this document. FUNDAMENTALS
[0002] Oral administration of pharmaceutical agents provides numerous conveniences to the patient, including limiting visits to the physician and avoiding more invasive drug delivery approaches such as injection or rectal administration. The colon can be a treatment site and / or a drug delivery site; however, the colon's location near the end of the gastrointestinal tract makes effective oral administration for release in the colon difficult. For example, an ingested oral drug dosage form must withstand the adverse pH conditions in the stomach, as well as the completely different pH conditions downstream of the stomach, and the mechanical stress applied by digestive processes before reaching the colon. The capabilities of conventional colon-targeted oral drug dosage forms vary in specificity and achieved release profiles.For example, some conventional colon-targeted oral drug dosage forms continuously release the drug throughout the gastrointestinal tract before the oral drug dosage form reaches the colon. This results in reduced drug availability in the colon, limited applicability to the active agents that can be released, and a higher likelihood of...

[0056] In some aspects, an oral drug dosage form is provided in this document, configured to release a drug at a desired location in an individual's colon, the oral drug dosage form comprising: a drug component comprising an erodible material mixed with the drug; and a delay component not mixed with the drug, wherein the delay component is configured to prevent the release of the drug from the drug component until the oral drug dosage form reaches the individual's colon after administration, and wherein the delay component comprises: a pH-based enteric element comprising an erodible material configured to erode at or above a predetermined pH value. In some embodiments, the oral drug dosage form is configured so that essentially all of the drug, for example, 100%, in the oral drug dosage form is released into an individual's colon. Petition 870250088298, dated 09 / 29 / 2025, p. 44 / 266 28 / 181
[0057] The oral drug dosage forms described in this document are based on the inventors' unique insights and findings regarding the design and production of oral drug dosage forms for precise drug release in the colon of the gastrointestinal tract. As taught and demonstrated in this document, in certain aspects, the oral drug dosage forms are capable of achieving complete drug release in the colon (including complete release in a specific area of the colon), which allows maximizing the therapeutic efficacy of certain drugs while minimizing side effects caused by drug release in another area of the gastrointestinal tract. For example, this toxicity can occur when there is unwanted systemic absorption due to drug release in another area of the gastrointestinal tract.The colon is susceptible to a variety of pathological conditions, including inflammatory bowel disease, irritable bowel syndrome, constipation, diarrhea, infections, and carcinoma. The oral drug dosage forms taught in this document are, in certain respects, capable of effectively delivering a drug to the site of a pathological condition, namely the colon, to provide effective local therapy. Furthermore, in other respects, the colon is a site in the gastrointestinal tract that provides the potential for effective absorption and thus systemic release. For example, the colon has comparatively lower levels of several luminal and mucosal metabolic enzymes (e.g., proteases) and transporters, which confers therapeutic advantages for certain drugs that would otherwise not be absorbed into the systemic circulation if released elsewhere in the gastrointestinal tract.For example, lower proteolytic activity in the colon may be beneficial for the release of biological products (e.g., peptides, proteins, monoclonal antibodies, nucleic acids, and vaccines). The capacity of the oral drug dosage forms taught. Petition 870250088298, dated 09 / 29 / 2025, page 45 / 266 29 / 181 in this document to promote complete release in the colon (including release in a specific area of the colon) represents a significant advance in the field of drug delivery, for both local and systemic therapies.
[0058] An illustrative example of the usefulness of certain oral drug dosage forms provided in this document can be found in the oral drug dosage forms described herein, which are configured with a drug for the treatment of ulcerative colitis. Ulcerative colitis is a condition that affects a specific area of the gastrointestinal tract, namely, ulcerative colitis causes inflammation and ulcers in the innermost layer of the large intestine (colon) and rectum. Known agents, such as anti-inflammatory drugs including JAK inhibitors, are effective in treating an individual with ulcerative colitis by reducing inflammation and ulcer formation. However, conventional drug dosage forms comprising these drugs have demonstrated limitations, such as incomplete drug release at the site of need.This release outside the colon reduces the effectiveness of these conventional oral drug dosage forms and can lead to systemic toxicity. The advantages of the oral drug dosage forms described in this document provide a significant improvement in the treatment of conditions such as ulcerative colitis.
[0059] Traditionally, the oral release of biological products, such as peptides, proteins, monoclonal antibodies, and nucleic acids (e.g., RNA / ) is limited due, at least partially, to the presence of digestive enzymes in the gastrointestinal tract. Vaccines can also face high levels of degradation due to phagocytosis rates. The lower level of functional proteolytic enzymes, functional pancreatic digestive enzymes, and phagocytosis in the colon, in comparison Petition 870250088298, dated 09 / 29 / 2025, page 46 / 266 30 / 181 interaction with other areas of the gastrointestinal tract represents an opportunity if these biological agents can be safely released into the colon. In certain aspects, the oral drug dosage forms taught in this document can protect a biological drug until its release in the colon, thus providing a significant advance in the oral delivery of these therapeutic agents.
[0060] Therefore, in certain respects, an oral drug dosage form is provided in this document, configured to release a drug at a desired location in an individual's colon, the oral drug dosage form comprising: a drug component comprising an erodible material mixed with the drug; and a delay component not mixed with the drug, wherein the delay component is configured to prevent the release of the drug from the drug component until the oral drug dosage form reaches the individual's colon after administration, wherein the delay component comprises: a pH-based enteric element comprising an erodible material configured to erode at or above a predetermined pH value.In some embodiments, the delay component further comprises an erodible delay element, wherein the oral drug dosage form is configured such that the pH-based enteric element erodes before the erodible delay element.

[0077] In some aspects, an oral drug dosage form is provided that is configured to release a drug at a desired site in the colon. As described in this document, in some embodiments, the oral drug dosage form configured to release a drug at a desired site in an individual's colon comprises: a drug component comprising an erodible material mixed with the drug; and a delay component not mixed with the drug, wherein the delay component is configured to prevent the release of the drug from the drug component until the dosage form of Petition 870250088298, dated 09 / 29 / 2025, page 52 / 266 36 / 181 Oral drug dosage form reaches the individual's colon after administration, and wherein the delay component comprises: a pH-based enteric element comprising an erodible material configured to erode at or above a predetermined pH value. In some embodiments, the oral drug dosage form has one or more additional features, for example, an erodible delay element, a second drug and, optionally, a second drug component, a bacterial degradation portion and, optionally, a bacterial degradation element, a shell or an excipient. The oral drug dosage forms described in this document may comprise a variety of combinations of the components described in this document and may be arranged in a variety of configurations.In some examples, such as those provided in the section below, components and configurations are described in a modular manner, and such description is not intended to limit the scope of oral drug dosage forms encompassed in this document. A. Exemplary oral drug dosage forms
[0078] For the purposes of illustrating and explaining the subject matter provided in this document, certain oral drug dosage forms covered in this document are described in detail below.
[0079] Exemplary cross-sectional schematic diagrams of oral drug dosage forms configured to release a drug at a desired site in the colon are provided in FIGS. 1A-1H. As illustrated in FIG. 1A, in some embodiments, the oral drug dosage form 100 comprises a drug component 102 comprising an erodible material mixed with a drug; and a delay component not mixed with the drug, wherein the delay component is configured to prevent the release of the drug from the drug component until the drug dosage form Petition 870250088298, dated 09 / 29 / 2025, page 53 / 266 37 / 181 oral reaches the individual's colon after administration, and wherein the delay component comprises an enteric-based element with a pH of 104 comprising an erodible material configured to erode at or above a predetermined pH value. After administration, the outer surfaces, which constitute the enteric-based element with a pH of 104, are exposed to the individual's gastrointestinal fluid. Once a pH threshold is reached, for example, based on a pH in or near the colon, or in a part thereof, the material on the surfaces of the pH 104 enteric-based element erodes from the oral drug dosage form, as shown by the direction of arrows 106, 108, 110 and 112. Based on the design of the pH 104 enteric-based element, the drug component 102, or parts thereof (such as surfaces), can be exposed in a controlled manner to gastrointestinal fluid to control drug release from the oral drug dosage form 100.For example, by having a thinner thickness (as assessed along the erosion direction and compared, for example, to the lateral thicknesses) of the pH 104 enteric-based element above and below the drug component 102, the erosion of the pH 104 enteric-based element will first expose an upper surface 114 and a lower surface 116 of the drug component 102. The drug mixed with the drug component 102 can then be released from the oral drug dosage form 100, such as by erosion. The ability to design which aspect(s) of the drug component 102 is / are exposed to the gastrointestinal fluid enables, at least partially, a controlled release of the drug from the oral drug dosage form 100.
[0080] As illustrated in FIG. 1B, in some embodiments, the delay component additionally comprises an erodible delay element 204 not mixed with the drug. After administration, the outer surfaces of the oral drug dosage form 200, Petition 870250088298, dated 09 / 29 / 2025, page 54 / 266 38 / 181, which constitutes the pH 202 enteric-based element, are exposed to the gastrointestinal fluid in the individual. Once a pH threshold is reached, for example, based on a pH in or near the colon, or a part thereof, the material on the surfaces of the pH 202 enteric-based element erodes from the oral drug dosage form 200, as shown by the direction of arrows 208 and 210. Based on the design of the pH 202 enteric-based element, the erodible delay element 204, or parts thereof (such as surfaces), can be exposed in a controlled manner to the gastrointestinal fluid. Based on exposure to the gastrointestinal fluid, the erodible delay element 204 will erode accordingly, and then aspects of the drug component 206 will be exposed to the gastrointestinal fluid, thus providing drug release from the oral drug dosage form 100.The design of the delay component may expose certain aspects of the drug component 206, such as allowing, at least partially, a controlled-release drug profile of the oral drug dosage form 200 to be obtained.
[0081] As illustrated in FIGS. 1C and 1D, in certain respects, the oral drug dosage forms provided in this document, for example, 300 and 400, comprise more than one component, for example, drug components. These dosage forms may be designed for sequential erosion (or at least partially sequential erosion), for example, as shown for the drug components in FIG. 1C, or compartment-based erosion, for example, as shown for the drug components in FIG. 1D. Specifically, as illustrated in FIG. 1C, after administration, the outer surfaces of the oral drug dosage form 300, which constitute the pH 302-based enteric element, are exposed to the individual's gastrointestinal fluid. Once a pH threshold is reached, for example, based on a pH at or near Petition 870250088298, dated 09 / 29 / 2025, page 55 / 266 39 / 181 of the colon, or a part thereof, the material on the surfaces of the pH 302 enteric-based element erodes from the oral drug dosage form, as shown by the direction of arrows 310 and 312. Based on the design of the pH 302 enteric-based element, the erodible retardant element 304, or parts thereof (such as surfaces), can be exposed in a controlled manner to gastrointestinal fluid. Based on exposure to gastrointestinal fluid, the erodible delay element 304 will erode accordingly, and then aspects of the second drug component 306 will be exposed to the gastrointestinal fluid, thus providing a release of a second drug from the oral drug dosage form 300. Based on exposure to gastrointestinal fluid, the second drug component 306 will erode accordingly, and then aspects of the drug component 308 will be exposed to the gastrointestinal fluid, thus providing the release of the drug from the oral drug dosage form 300.The design of the delay component may expose certain aspects of the second drug component 306 so that a controlled-release profile of the second drug of the oral drug dosage form 300 is obtained. The design of the delay component and / or the second drug component 306 may expose certain aspects of the drug component 308 so that a controlled-release profile of the drug of the oral drug dosage form 300 is obtained. The drug and the second drug may be the same or different. In some embodiments, an intermediate material is positioned between at least part of the second drug component 306 and the drug component 308, such as an erodible second delay element.
[0082] As illustrated in FIG. 1 D, a compartment-based approach can be adopted to design an oral drug dosage form 400 taught in this document. After administration, the outer surfaces of the oral drug dosage form 400, which Petition 870250088298, dated 09 / 29 / 2025, page 56 / 266 40 / 181 constitutes the enteric-based element with pH 402, and is exposed to gastrointestinal fluid in the individual. Once a pH threshold is reached, for example, based on a pH in or near the colon, or a part thereof, the material on the surfaces of the enteric-based element with pH 402 erodes from the oral drug dosage form 400, as shown by the direction of arrows 410 and 412. Based on the design of the enteric-based element with pH 402, the erodible retardant element 404, or parts thereof (such as surfaces), can be exposed in a controlled manner to gastrointestinal fluid. Based on exposure to gastrointestinal fluid, the erodible delay element 404 will erode accordingly, and then aspects of the drug component 406 and the second drug component 408 will be exposed to the gastrointestinal fluid, thus providing the release of the drug and a second drug, respectively, from the oral drug dosage form 400.The design of the delay component can control drug release, such as achieving, for example, separate drug release, simultaneous drug release, or partially overlapping drug release. In some embodiments, a second erodible delay element is associated with the second drug component 408, such that the second drug component 408 does not depend on the erodible delay element 404 for drug release. As described in this document, oral drug dosage forms may contain many compartments containing the drug and / or other aspects of the oral drug dosage form, for example, a bacterial degradation moiety and / or an excipient.
[0083] As described in this document, certain other components may be formulated in the oral drug dosage forms provided in this document, for example, a bacterial degradation moiety (such as mixed into a bacterial degradation element) and an excipient. For example, as illustrated in Petition 870250088298, dated 09 / 29 / 2025, page 57 / 266 41 / 181 FIG. 1E, after administration, the outer surfaces of the oral drug dosage form 500, which constitute the pH-based enteric element 502, are exposed to the gastrointestinal fluid in the individual. Once a pH threshold is reached, for example, based on a pH in or near the colon, or a part thereof, the material on the surfaces of the pH-based enteric element 502 erodes from the oral drug dosage form 500, as shown by the direction of arrows 510 and 512. Based on the design of the pH-based enteric element 502, the erodible retardant element 504, or parts thereof (such as surfaces), can be exposed in a controlled manner to the gastrointestinal fluid. Based on exposure to the gastrointestinal fluid, the erodible retardant element 504 will erode correspondingly, and then aspects of the bacterial degradation element mixed with a bacterial degradation portion 506 will be exposed to the gastrointestinal fluid.The bacterial degradation element 506 is then degraded to expose aspects of the drug component 508, thus providing a drug release from the oral drug dosage form 500. The design of the delay component (in FIG. 1E, the delay component comprises the pH-based enteric element 502, the erodible delay element 504, and the bacterial degradation element 506) can expose certain aspects of the drug component 508 so that a controlled drug release profile from the oral drug dosage form 500 is obtained.
[0084] In some respects, the oral drug dosage forms provided in this document comprise a shell. As illustrated in FIGS. 1F-1H, the oral drug dosage form 600 is configured to release a drug at a desired site in the colon, the oral drug dosage form comprising: a drug component comprising a first erodible material mixed with a drug; a shell not mixed with the drug, wherein the Petition 870250088298, dated 09 / 29 / 2025, page 58 / 266 42 / 181 The casing is associated with at least part of the drug component, such as by means of one or more sides of the drug component; and a retarding component not mixed with the drug, the retarding component comprising: a pH-based enteric element configured to erode at or above a predetermined pH value; and an erodible retarding element comprising an erodible material.

[0086] The oral drug dosage form 600 of FIG. 1F is configured so that, when administered to a human subject, the oral drug dosage form begins a journey through the human subject's gastrointestinal system, and once the form of Petition 870250088298, dated 09 / 29 / 2025, page 60 / 266 44 / 181 oral drug dosage form 600 is subjected to a gastrointestinal fluid with a suitable pH value, such as a pH value of 5.5 or higher, an upper surface 622 of the first layer of the enteric base layer with pH 618 and a lower surface 626 of the second layer of the enteric base layer with pH 624 erode from the oral drug dosage form 600 in the direction of the respective arrows 628, 630. As shown in FIG. 1G, at a certain time after administration to the human subject, the first and second layers of the pH-based enteric element (618 and 624, as shown in FIG. 1F) eroded from the oral drug dosage form 600 and exposed the upper surface 616 of the first layer of the erodible lag element 612 and the lower surface 632 of the second layer of the erodible lag element 622 to a gastrointestinal fluid.The first and second layers of the erodible retardant element erode from the oral drug dosage form 600 in the direction of the respective arrows 634, 636. As shown in FIG. 1H, at a certain time after administration to the human subject, the first and second layers of the erodible retardant element (612 and 622, as shown in FIG. 1F and 1G) eroded from the oral drug dosage form 600 and exposed the upper surface 606 and lower surface 608 of the drug component 604, and the drug is released from the oral drug dosage form by means of erosion of the drug component 604, such as in the direction of arrows 638, 640. In some embodiments, the drug component breaks apart and at least a portion of the drug component may be released from the oral drug dosage form and additionally erode to release the drug into the human subject.
[0087] As described in this document, certain other components may be formulated in the oral drug dosage forms provided in this document, for example, a portion of Petition 870250088298, dated 09 / 29 / 2025, page 61 / 266 45 / 181 bacterial degradation (such as mixed in a bacterial degradation element) and an excipient. For example, as illustrated in FIG. 11.

[0088] This descriptive report provides additional formats of oral drug dosage forms. For example, as illustrated in FIG. 1J. Oral drug dosage form 800 comprises a shell 802 comprising an insulating material impermeable to body fluids and a drug component 804 comprising a first erodible material mixed with a drug. As illustrated in FIG. 1J, the drug component 804 forms a layer comprising an upper surface 806, a lower surface 808 and one or more sides, for example, 810, wherein one or more sides of the drug component layer are associated with, such as in direct contact with, the shell. The use of directional terms such as upper, lower and sides is intended to facilitate the description of the invention provided herein and should not be construed as limiting the scope of the inventions provided herein. Petition 870250088298, dated 09 / 29 / 2025, p. 63 / 266 47 / 181 The bacterial degradation element 832 is then degraded to expose aspects of the drug component 806 and 808, thus providing a release of the drug from the oral drug dosage form 800. The delay component of the oral drug dosage form 800 is not mixed with the drug, and the delay component comprises: an enteric pH-based element configured to erode at or above a predetermined pH value; and an erodible delay element comprising an erodible material, wherein the enteric pH-based element and the casing prevent erosion of the erodible delay element, and wherein the erodible delay element and the casing prevent erosion of the drug component. Specifically, in the oral drug dosage form 800 of FIG.1J, the delay component comprises a pair of layer sets of a first layer of the erodible delay element 812, a first layer of the pH-based enteric element 818, a second layer of the erodible delay element 822 and a second layer of the pH-based enteric element 824.

In some embodiments, the oral drug dosage form is configured so that the drug component is released from the oral drug dosage form at some point after administration, for example, after erosion of another component of the drug dosage form, such as the bacterial degradation element. In these embodiments, the release of the drug from the drug component will consider, for example, the surface area of the drug component exposed to a gastrointestinal fluid.
[0089] In certain respects, the oral drug dosage forms provided in this document comprise a first enteric pH-based element and a second enteric pH-based element. As illustrated in FIG. 1K, after administration, the outer surfaces of the oral drug dosage form 900, which constitute the first enteric pH-based element 902, are exposed to the gastrointestinal fluid in the individual. Once the pH threshold is reached, for example, based on or above a pH value of about 5.5, or a portion thereof, the material of the first enteric pH-based element 902 erodes from its surface, as shown by the direction of arrows 910 and 912. Based on the design of the first enteric pH-based element 902, gastric juice can be prevented from penetrating the oral drug dosage form 900.Then, once the second pH limit is reached, for example, based on a pH in or near the colon, or a part thereof, the material on the surfaces of the second enteric-based element with pH 906 will erode from the oral drug dosage form 900. Based on the design of the second enteric-based element with pH 906, drug release in the small intestine can be prevented. Based on the design of the first enteric-based element with pH 902 and the second enteric-based element with pH 906, the... Petition 870250088298, dated 09 / 29 / 2025, pp. 65 / 266 49 / 181 erodible delay element 904, or parts thereof (such as surfaces), may be exposed in a controlled manner to gastrointestinal fluid. Based on exposure to gastrointestinal fluid, the erodible delay element 904 will erode accordingly, thus providing drug release from the oral drug dosage form 900. The design of the delay component (in FIG. 1K, the delay component comprises the first enteric-based element at pH 902, the second enteric-based element at pH 906, and the erodible delay element 904) may expose certain aspects of the drug component 908 so that a controlled drug release profile of the oral drug dosage form 900 is obtained.
[0090] In some embodiments, the description of the oral drug dosage forms provided in this document, and associated methods, is facilitated by the description of the thickness of a component, such as a layer of an erodible retardant element. In some embodiments, the thickness of a component, such as a layer of an erodible retardant element, is measured from a surface, such as the top surface, in a direction substantially parallel to the erosion direction. For example, as shown in FIG. 1G, the thickness of a layer of an erodible retardant element not mixed with drug 612 is provided.
[0091] An exemplary oral drug dosage form comprising a drug is provided in FIG. 2.

After administration, erosion of the pH-based enteric element layers exposes two layers of the erodible delay element to the gastrointestinal fluid such that these two layers of the erodible delay element then begin to erode. Erosion of one of the layers of the erodible delay element exposes a surface of the drug component. Erosion of one of the layers of the erodible delay element exposes another layer of the erodible delay element (described as a VA64 layer, but not limited to such material) on one side of the drug component. After erosion of the VA64 layer of the erodible delay element, another surface of the drug component is exposed.The exposed surfaces of the drug component erode to release the drug from the oral dosage form. As illustrated in FIG. 2, the oral dosage form may contain tracking features, such as tracking bands and / or loops. Such tracking bands are useful for the development and optimization of an oral dosage form, for example, obtaining images of an individual, such as through the use of x-rays, after administration can be used to determine the location of erosion of aspects of the drug dosage form. Oral dosage forms without one or more of the tracking bands are also encompassed by the invention provided in this document. For example, after the development and optimization of the oral dosage form, the tracking bands may no longer be necessary.In these cases, the tracking strip portion can be replaced by the material in which it is incorporated and / or additional adjustments can be made, such as adjusting one or more [sections / parts]. Petition 870250088298, dated 09 / 29 / 2025, page 67 / 266 51 / 181 drug component features (e.g., surface area, thickness, drug mass percentage) to compensate for the absence of the tracking strip.

[0094] An exemplary oral drug dosage form comprising a drug is provided in FIG. 3. As shown in FIG. 3, the oral drug dosage form comprises a non-containing shell. Petition 870250088298, dated 09 / 29 / 2025, page 69 / 266 53 / 181 mixed with the drug, an internal drug component comprising a first erodible material mixed with a drug, and a delay component not mixed with the drug, wherein the delay component comprises two layers of a pH-based enteric element configured to erode at or above a predetermined pH value and two layers of an erodible delay element comprising an erodible material, wherein each layer of the pH-based enteric element and the casing prevent the erosion of a respective layer of the erodible delay element, and wherein the erodible delay element and the casing prevent the erosion of the drug component. After administration, the erosion of the pH-based enteric element layers then exposes the erodible delay element layers to the gastrointestinal fluid, so that the erodible delay element layers then begin to erode.The erosion of the layers of the erodible retarding element then exposes surfaces of the drug component, so that the erosion of these releases the drug from the oral dosage form. As illustrated in FIG. 3, the oral dosage form may contain tracking bands. Such tracking bands are useful for the development and optimization of an oral dosage form, for example, obtaining images of an individual, such as by using x-rays, after administration can be used to determine the location of erosion of aspects of the drug dosage form. Oral dosage forms without one or more of the tracking bands are also encompassed by the invention provided in this document.

Delay components
[0178] The oral drug dosage forms described in this document comprise a delay component configured to control, such as preventing and / or inhibiting, the release of a drug from the oral drug dosage form so as to release the drug at the desired site in the colon. As described in this document, the delay component is not mixed with the drug of the drug component. In some embodiments, the delay components do not contain a Petition 870250088298, dated 09 / 29 / 2025, pp. 116 / 266 100 / 181 drug, such as an active pharmaceutical ingredient. In some embodiments, the delay component comprises another drug. In addition, aspects of the delay component may be mixed with another agent, such as a bacterial degradation moiety or an excipient.
[0179] In some embodiments, the delay component surrounds the drug component. In some embodiments, the delay component completely surrounds the drug component.
[0180] In some embodiments, the delay component (such as through aspects thereof) surrounds at least partially, for example, in layers, a drug component. For example, in some embodiments, the drug component is intercalated between two erodible delay layers, which in turn are intercalated between two pH-based enteric layers. In some embodiments, the delay component is formed by any number of layers of pH-based enteric layers and erodible delay layers. In some embodiments, when a drug component is at least partially surrounded, for example, intercalated, by layers of the delay component, the layers may form symmetrical or asymmetrical structures. For example, in some embodiments, the drug component is intercalated between two erodible delay layers, which in turn are intercalated between two pH-based enteric layers.In some embodiments, the drug component is sandwiched between two erodible retardant layers, wherein an additional erodible retardant layer is added to a surface distal to the drug component of one of the two erodible retardant layers, and wherein the drug component and the erodible retardant layers are sandwiched between two pH-based enteric layers. Petition 870250088298, dated 09 / 29 / 2025, p. 117 / 266 101 / 181 / '. pH-based enteric elements

[0182] In some embodiments, the oral drug dosage form comprises one or more pH-based enteric elements, wherein the one or more pH-based enteric elements may be the same or different from each other, such as having the same or different shape, size and / or constitution. For example, in some embodiments, the oral drug dosage form comprises a first pH-based enteric element and a second pH-based enteric element. In some embodiments, the first pH-based enteric element and the second pH-based enteric element have different pHs, at which the respective materials begin to erode. In some embodiments, the oral drug dosage form is configured so that a first pH-based enteric element erodes before a second pH-based enteric element is exposed to a body fluid after administration to an individual.
[0183] The pH-based enteric element is configured to erode at or above a desired pH value. As recognized in the field, different regions of the human gastrointestinal tract have environments with different pHs. The use of such pH-based enteric elements helps control the erosion of this component from the oral drug dosage forms described in this document to a desired location in the gastrointestinal tract. In some embodiments, the pH-based enteric element erodes at a pH value between about 5.5 and about 8, such as between any of about 5.5 and about 7.5 and about Petition 870250088298, dated 09 / 29 / 2025, p. 118 / 266 102 / 181 from 6 to about 7.

In some embodiments, the pH-based enteric elements are configured to have surfaces, such as a surface exposed to a body fluid during the administration of the oral drug dosage form to a human subject, with a predetermined shape and surface area. For example, in some embodiments, the pH-based enteric element has a top surface and a bottom surface, where the top surface is exposed to a body fluid before the bottom surface. In some embodiments, the pH-based enteric element is a layer with a top surface and a bottom surface.In some embodiments, the upper surface of the pH-based enteric element is not flat; for example, it comprises certain features that extend beyond a top surface plane or surface tolerance limit (as measured between two parallel planes), such as to reduce the adhesion of the pH-based enteric element, or a portion thereof, to an internal part of the human body. In some embodiments, the upper surface of the pH-based enteric element, or at least a portion thereof, is flat or is within a surface tolerance limit.
[0185] In some embodiments, the pH-based enteric element surrounds the drug component. In these embodiments, there may be no additional material between the pH-based enteric element or there may be additional material between the pH-based enteric element.

[0267] Different 3D printing methods have been developed for manufacturing in terms of raw materials, equipment, and solidification. These 3D printing methods include binder deposition (see Gibson et al., Additive Manufacturing Technologies: 3D Printing, Rapid Prototyping, and Direct Digital Manufacturing, 2nd ed. Springer, New York, 2015; Katstra et al., Oral dosage forms fabricated Petition 870250088298, dated 09 / 29 / 2025, pp. 166 / 266 150 / 181 by three dimensional printing, J Control Release, 66, 2000; Katstra et al., Fabrication of complex oral delivery forms by three dimensional printing, Dissertation in Materials Science and Engineering, Massachusetts Institute of Technology, 2001; Lipson et al., Fabricated: The New World of 3D printing, John Wiley & Sons, Inc., 2013; Jonathan, Karim 3D printing in pharmaceutics: a new tool for designing customized drug delivery systems, Int J Pharm, 499, 2016), jateamento de material (vide Jonathan, Karim, 3D printing in pharmaceutics: a new tool for designing customized drug delivery systems, Int J Pharm, 499, 2016), extrusão (vide Gibson et al., Aditive Manufacturing Technologies: 3D Printing, Rapid Prototyping, and Direct Digital Manufacturing. 2 ed.

[0268] In some embodiments, the oral drug dosage forms described in this document are 3D printed using an extrusion method. In some embodiments, the 3D printing method comprises the use of a twin-screw extrusion method. In an extrusion process, material is extruded from robotically driven print heads through print nozzles. Unlike binder deposition, which requires a powder bed, extrusion methods can print on any substrate. A variety of materials can be extruded for three-dimensional printing, including thermoplastic materials described in this document, pastes and colloidal suspensions, silicones, and other semi-solids. One extrusion printing method is extrusion-fused-deposition (EDD), which uses material extruded from a print head to print layers of material in order to form the components of the oral drug dosage form. Another common type of printing by Petition 870250088298, dated 09 / 29 / 2025, pp. 167 / 266 151 / 181 Extrusion is fused deposition modeling, which uses solid polymer filaments for printing. In fused deposition modeling, a gear system drives the filament through a set of heated nozzles for extrusion (see Gibson et al., Additive Manufacturing Technologies: 3D Printing, Rapid Prototyping, and Direct Digital Manufacturing, 2nd ed. Springer, New York, 2015).

In some embodiments, 3D printing is performed by MED and semi-solid extrusion, for example, semi-solid extrusion to produce a drug component mixed with a biological drug and MED to produce other components. In some embodiments, 3D printing is performed by MED to produce a lag or shell component, and then 3D printing is performed by semi-solid extrusion to produce a drug component mixed with a biological drug at lower temperatures than MED. In some embodiments, the drug in the drug component can be kept stable by means of semi-solid extrusion.
[0270] In some embodiments, 3D printing is performed by extrusion-fused-to-deposition (EDD). In some embodiments, the EFD technique involves preparing a material to be dispensed, such as preparing a powder in a hot melt extruder, and then feeding the material into an EFD print head. The EFD print head then dispenses the material to form the oral drug dosage form in an additive manner (layer-by-layer deposition). In some embodiments, each material of the oral drug dosage form, such as the extended-release drug component, the element Petition 870250088298, dated 09 / 29 / 2025, pp. 168 / 266 152 / 181 of delay and the envelope, is dispensed from a different MED printhead. In some embodiments, the MED printhead dispenses the material according to instructions compiled in one or more G-code files. Exemplary MED techniques are described in, for example, WO2018 / 210183, WO2019 / 137333, WO2018137686 and U.S. Patent No. 10,201,503, each of which is incorporated herein in its entirety.
