Abstract: The present invention provides methods of forming a solid, biodegradable implant in-situ in a body by administering a liquid pharmaceutical composition comprising an effective amount of a biocompatible, water-insoluble, biodegradable polymer and an effective amount of a therapeutic peptide covalently modified with one or more lipophilic or amphiphilic moieties, which are dissolved or dispersed in a biocompatible, water-soluble organic solvent. This invention also provides related compositions and methods.

Abstract: The present invention provides for a stabilized biodegradable polymeric composition useful as a controlled release delivery system for peptide agents. The compositions of the present invention comprise a) a beneficial salt of a peptide agent formed with a strong acid that minimizes or prevents the interaction/reaction between the peptide agent and the polymer in an organic solution; b) a biodegradable polymer; c) a pharmaceutically acceptable organic solvent; and d) optionally one or more excipients. The present invention also relates to a method of manufacturing and a method of use thereof.
