Chiem V. Pham has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Acid end group poly(D,L-lactide-co-glycolide) copolymers with high glycolide content
    Patent number: 7074883
    Abstract: Copolymers of lactide and glycolide with high glycolide content. The average glycolate block length is less then about 3, which allows the copolymer to be soluble in slightly polar solvents such as methylene chloride.
    Type: Grant
    Filed: December 1, 2003
    Date of Patent: July 11, 2006
    Assignee: Alkermes Controlled Therapeutics, Inc. II
    Inventor: Chiem V. Pham
  • Injectable sustained release compositions
    Publication number: 20040247672
    Abstract: The present invention relates to a polymer paste and a sustained release composition comprising the paste and a biologically active agent. The polymer paste comprises a biocompatible, biodegradable polymer having an inherent viscosity of about 0.12 dL/g or less and a viscosity reducing agent, wherein the biocompatible, biodegradable polymer is present in the polymer paste in at least 60% by weight and the viscosity of the paste is about 400 cP or less. The sustained release composition comprises a biologically active agent and a polymer paste comprising a biocompatible, biodegradable polymer having an inherent viscosity of about 0.12 dL/g or less and a viscosity reducing agent, wherein the biocompatible, biodegradable polymer is present in the polymer paste in at least 60% by weight and the viscosity of the sustained release composition is about 400 cP or less. In a particular embodiment, the sustained release composition is injectable.
