Abstract

Residence structures, systems, and related methods are generally provided. Certain embodiments comprise administering (e.g., orally) a residence structure to a subject (e.g., a patient) such that the residence structure is retained at a location internal to the subject for a particular amount of time (e.g., at least about 24 hours) before being released. The residence structure may be, in some cases, a gastric residence structure. In some embodiments, the structures and systems described herein comprise one or more materials configured for high levels of active substances (e.g., a therapeutic agent) loading, high active substance and/or structure stability in acidic environments, mechanical flexibility and strength in an internal orifice (e.g., gastric cavity), easy passage through the GI tract until delivery to at a desired internal orifice (e.g., gastric cavity), and/or rapid dissolution/degradation in a physiological environment (e.g., intestinal environment) and/or in response to a chemical stimulant (e.g., ingestion of a solution that induces rapid dissolution/degradation). In certain embodiments, the structure has a modular design, combining a material configured for controlled release of therapeutic, diagnostic, and/or enhancement agents with a structural material necessary for gastric residence but configured for controlled and/or tunable degradation/dissolution to determine the time at which retention shape integrity is lost and the structure passes out of the gastric cavity. For example, in certain embodiments, the residence structure comprises a first elastic component, a second component configured to release an active substance (e.g., a therapeutic agent), and, optionally, a linker. In some such embodiments, the linker may be configured to degrade such that the residence structure breaks apart and is released from the location internally of the subject after a predetermined amount of time.

First claim

What is claimed is:

1. A gastric residence structure, comprising:
an elastic polymeric component;
a first polymeric component coupled to the elastic component via a separate first degradable linker;
a second polymeric component coupled to the first polymeric component via a separate second degradable linker;
wherein each linker component is the same or different,
and wherein at least one linker degrades, dissolves, disassociates, or mechanically weakens in a gastric environment which results in loss of retention shape integrity and passage out of a gastric cavity,
wherein the residence structure is configured such that it is retained at the location internally of the subject for at least about 24 hours,
wherein the structure is configured to be folded and physically constrained during administration and is configured to assume an open retention shape upon removal of a constraint, wherein change between the folded shape and the open retention shape is mediated by the elastic polymeric component that undergoes elastic deformation when the residence structure is in the folded shape and recoils when the gastric residence structure assumes the open retention shape.

2. A gastric residence structure as in claim 1 , wherein the first polymeric component and/or the second polymeric component comprises a first active substance.

3. A gastric residence structure as in claim 1 , wherein the first degradable linker is a time dependent degradable linker.

4. A gastric residence structure as in claim 1 , wherein the second degradable linker comprises an enteric polymer.

5. A gastric residence structure as in claim 2 , wherein the first polymeric component and the second polymeric component comprises the first active substance.

6. A gastric residence structure as in claim 5 , wherein the second polymeric component comprises a second active substance.

7. A gastric residence structure as in claim 6 , wherein the second active substance is different than the first active substance.

8. A gastric residence structure as in claim 1 , wherein the active substance is a radiopaque material.

9. A gastric residence structure as in claim 5 , wherein the structure releases between about 0.05 wt % and about 30 wt % of the active substance during the first day of release.

10. A gastric residence structure as in claim 1 , wherein the elastic polymeric component is free of active substance.

11. A gastric residence structure as in claim 5 , wherein the first polymeric component comprises at least 10 wt % active substance of the total weight of the first polymeric component.

12. A gastric residence structure as in claim 6 , wherein the second polymeric component comprises at least 10 wt % active substance of the total weight of the second polymeric component.

13. A gastric residence structure as in claim 1 , wherein the residence structure is retained in the stomach of the subject for at least about 1 week.

14. A gastric residence structure as in claim 2 , wherein the first active substance is a biological macromolecule, a small molecule, a vitamin, or a supplement.

15. A gastric residence structure as in claim 2 , wherein the first active substance is a selective serotonin reuptake inhibitor, a blood thinning agent, a steroid, an antagonist, a cardiac glycoside, an alpha blocker, a cholesterol absorption inhibitor, a metabolite, an antihistamine, an opioid, a proton-pump inhibitor, an antibiotic, an anti-malarial agent, sulfonamides, a substance abuse treatment, a contraceptive, a stimulant, an analgesic, an anti-analgesic, an anti-inflammatory drug, a nonsteroidal anti-inflammatory drug, an antipyretic, an immunosuppressant, a neuroprotective agent, an antipsychotic, a statin, an antidepressant, an antiepileptic, an anti-proliferative, an anti-cancer agent, an antimigraine drug, an antimicrobial, an antifungal, an antiviral agent, an antiretroviral agent, an antiparasitic, an antimuscarinic, an anxiolytic, a bacteriostatic, a sedative, a hypnotic, a bronchodilator, an anti-asthma drug, a cardiovascular drug, an anesthetic, an anticoagulant, a dopaminergic, an electrolyte, a gastrointestinal drug, a muscle relaxant, a parasympathomimetic, an anorectic, an anti-narcoleptic, a protein, a peptide, a hormone, a nucleic acid, a gene construct, 3-hydroxy-3-methyl-glutaryl (HMG) co-A reductase inhibitor, a mineral, a prostaglandin, a nutritional supplement, a corticosteroid, a nutraceutical, a plant extract, or a phytohormone.
