Abstract: Gastric residence systems and methods of delivering a drug to an individual using a gastric residence system are described herein. The gastric residence system may include a time-dependent and/or enteric, or dual time-dependent and enteric polymeric linker. In some embodiments, the time-dependent polymeric linker includes PLGA, and optionally PLA or a carrier polymer. The enteric polymeric linker includes an enteric polymeric, and optionally a carrier polymer such as PCL or TPU. The time-dependent polymeric linker may degrade in the stomach of the individual according to a degradation (or flexural modulus loss) profile described herein, and the enteric polymeric linker may degrade in the intestine of the individual another degradation profile described herein (or flexural modulus loss).

Abstract: Gastric residence systems for administration of agents, such as drugs, are disclosed. Features which enhance gastric retention during the desired residence time and which allow for more precise control over residence time are disclosed, including circumferential filaments connecting the arms of a stellate gastric residence system; flexible arms for a gastric residence system; improved time-dependent and enteric disintegrating matrices (linkers); and release rate-modulating polymer coatings which are resistant to change in release rate properties during heat-assisted assembly or thermal cycling. Combinations of these features are also disclosed.

Abstract: Provided are enrobed gastric residence dosage forms comprising: a gastric residence system in a folded configuration; and a coating enrobing the gastric residence system in the folded configuration, wherein the enrobed gastric residence dosage form is configured to release the gastric residence system in the folded configuration in a stomach of a patient, allowing the gastric residence system to assume an open configuration. The coating comprises water, a plasticizer, a gelling agent, and/or a polymer.

Abstract: Provided are gastric residence dosage forms comprising: a gastric residence system in a folded configuration; a capsule encapsulating the gastric residence system in a folded configuration; and a coating on the capsule, wherein the gastric residence dosage form is configured to release the gastric residence system in a stomach of a patient, allowing the gastric residence system to assume an open configuration. The coating on the capsule includes a polymer, an anti-tacking agent, and/or a hydration aid.
