Sustained release formulation of a peptide

Abstract

This invention pertains to a sustained release complex, Compound (I), which comprises Compound (A), having the formula or a pharmaceutically acceptable salt thereof, and a copolymer comprising poly-(I)-lactic-glycolic-tartaric acid (P(I)LGT), wherein the amino group of said Compound (A) is ionically bound to a carboxyl group of the P(I)LGT. The present invention further pertains to a process for making said sustained release complex. Further still, the present invention is directed to a pharmaceutical composition comprising said sustained release complex and a pharmaceutically acceptable carrier(s).
