Publication number: 20200085736Abstract: 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.Type: ApplicationFiled: November 22, 2019Publication date: March 19, 2020Applicants: Massachusetts Institute of Technology, The Brigham and Women's Hospital, Inc.Inventors: Andrew Bellinger, Shiyi Zhang, Carlo Giovanni Traverso, Robert S.

Publication number: 20200030234Abstract: Enteric elastomers and related methods are generally provided. In some embodiments, the enteric elastomer is a polymer composite. Certain embodiments comprise a polymer composite in which hydrogen bonds within two carboxyl group-containing polymers cross-link the polymer networks into an elastic and pH-responsive polymer composite. Advantageously, this polymer composite has the capacity of being stable and elastic in an acidic environment such as that of the stomach but can be dissolved in a neutral pH environment such as that of the small and large intestines. In some embodiments, the polymer composites described herein comprise a mixture of two or more polymers with carboxyl functionality such that the two or more polymers form hydrogen bonds. In certain embodiments, the polymer composite has both enteric and elastic properties.Type: ApplicationFiled: July 31, 2019Publication date: January 30, 2020Applicants: Massachusetts Institute of Technology, The Brigham and Women's Hospital, Inc., Tokitae LLCInventors: Shiyi Zhang, Andrew Bellinger, Carlo Giovanni Traverso, Robert S.

Patent number: 10532027Abstract: Certain embodiments comprise administering 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. 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, and, optionally, a linker. In some such embodiments, the linker may be configured to degrade.Type: GrantFiled: November 1, 2018Date of Patent: January 14, 2020Assignees: Massachusetts Institute of Technology, The Brigham and Women's Hospital, Inc.Inventors: Andrew Bellinger, Shiyi Zhang, Carlo Giovanni Traverso, Robert S.

Patent number: 10517819Abstract: Described are gastric residence structures that include an active substance. The gastric residence structures may include one or more arms that include a loadable polymeric component, an elastic polymeric component, and a separate linker component. The linker may connect the one or more arms with the elastic polymeric component. The gastric residence structures may be configured to be folded and physically constrained during administration and may be configured to assume an open retention shape upon removal of a constraint. The change between the folded shape and the open retention shape may be 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.Type: GrantFiled: February 15, 2019Date of Patent: December 31, 2019Assignees: Massachusetts Institute of Technology, The Brigham and Women's Hospital, Inc.Inventors: Andrew Bellinger, Shiyi Zhang, Carlo Giovanni Traverso, Robert S.
