  • Stabilized polymeric carriers for therapeutic agent delivery
    Patent number: 10709791
    Abstract: Polymeric carriers for the delivery of therapeutic agents and methods for making and using the same. The polymeric carriers include copolymers, diblock copolymers, polymeric architectures that include the copolymers and diblock copolymers, and particles assemblies comprising the copolymers, diblock copolymers, and polymeric architectures that include the copolymers.
    Type: Grant
    Filed: November 12, 2015
    Date of Patent: July 14, 2020
    Assignee: University of Washington

  • RANDOM COPOLYMER THERAPEUTIC AGENT CARRIERS AND ASSEMBLIES THEREOF
    Publication number: 20190365906
    Abstract: Provided herein are particles assemblies including a shell surrounding a core. The shell includes a particle-stabilizing random copolymer. The core includes a core random copolymer. The particle assemblies have a biomimetic design in which the polymeric components containing discrete chemical and biological functionalities are designed to spontaneously self-assemble into particles. Also provided herein are random copolymers having conjugated therapeutic agents that can be cleaved from the copolymers by an enzyme or water.
