POLYMER-BASED COMPOSITIONS FOR SUSTAINED RELEASE

Title:

POLYMER-BASED COMPOSITIONS FOR SUSTAINED RELEASE

Document Type and Number:

WIPO Patent Application WO2003066585

Kind Code:

A3

Abstract:

This invention relates to sustained release compositions, and methods of forming and using said compositions, in particular for the sustained release of Follicle Stimulating Hormone (FSH). The sustained release compositions comprise a polymeric matrix of a biodegradable biocompatible polymer and stabilized FSH. The method of the invention for forming a sustained release composition includes, dissolving a biodegradable biocompatible polymer in a polymer solvent to form a polymer solution; adding biologically active stabilized FSH; removing the solvent; and solidifying the polymer to form a polymer matrix containing stabilized FSH dispersed therein. Also described is a method for providing a therapeutically effective amount of stabilized FSH in a patient in need of for a sustained period comprising administering to the patient a dose of the sustained release compositions of the invention. The sustained release composition of FSH can be used to promote maturation of follicles, promote spermatogenesis and to treat fertility disorders.
