Abstract

The present invention relates to a method for the sustained release in vivo of a biologically active agent comprising administering to a subject in need of treatment an effective amount of a sustained release composition comprising a biocompatible polymer having the biologically active agent incorporated therein, and a bisphosphonate wherein the bisphosphonate compound is present in an amount sufficient to modify the release profile of the biologically active agent from the sustained release composition. Pharmaceutical compositions suitable for use in the method of the invention are also disclosed.

Claims

1. A method for the sustained release in vivo of a biologically active agent comprising administering to a subject in need of treatment an effective amount of a sustained release composition comprising a biocompatible polymer having a biologically active agent incorporated therein, and a bisphosphonate wherein the bisphosphonate is present in an amount sufficient to modify the release profile of the biologically active agent from the sustained release composition.

2. The method of claim 1, wherein the bisphosphonate compound is co-incorporated into the sustained release composition.

3. The method of claim 1, wherein the bisphosphonate compound is separately incorporated into a second biocompatible polymer.

4. The method of claim 3, wherein the second biocompatible polymer is the same as the biocompatible polymer of the sustained release composition.

5. The method of claim 4, wherein the second biocompatible polymer is different from the biocompatible polymer of the sustained release composition.

6. The method of claim 1, wherein the bisphosphonate compound is unencapusulated but comingled with the sustained release composition.

7. The method of claim 1 wherein the the biocompatible, biodegradable polymer of the microparticle is selected from poly(lactides), poly(glycolides), poly(lactide-co-glycolides), poly(lactic acid)s, poly(glycolic acid)s, polycarbonates, polyesteramides, polyanydrides, poly(amino acids), polyorthoesters, poly(dioxanone)s, poly(alkylene alkylate)s, copolymers of polyethylene glycol and polyorthoester, polyurethanes, blends thereof, and copolymers thereof.

8. The method of claim 7 wherein the biocompatible, biodegradable polymer is a poly(lactide-co-glycolide).

9. The method of claim 1 wherein the bisphosphonate is alendronate, risendronate, pamidonate, etidronate, tiludronate or a combination thereof.

10. The method of claim 1, wherein the sustained release composition is in the form of microparticles.

11. The method of claim 1 wherein the biologically active agent is a protein, a peptide or a nucleic acid.

12. The method of claim 1 wherein the biologically active agent is a protein.

13. The method of claim 1 wherein the protein is erythropoietin.

15. The pharmaceutical composition of claim 14, wherein the bisphosphonate compound is co-incorporated into the sustained release composition.

16. The pharmaceutical composition of claim 14, wherein the bisphosphonate compound is separately incorporated into a second biocompatible polymer.

17. The pharmaceutical composition of claim 16, wherein the second biocompatible polymer is the same as the biocompatible polymer of the sustained release composition.

18. The phamaceutical composition of claim 16, wherein the second biocompatible polymer is different from the biocompatible polymer of the sustained release composition.

19. The pharmaceutical compositin of claim 14, wherein the bisphosphonate compound is unencapusulated but comingled with the sustained release composition.

20. The pharmaceutical composition of claim 14 wherein the the biocompatible, biodegradable polymer of the microparticle is selected from poly(lactides), poly(glycolides), poly(lactide-co-glycolides), poly(lactic acid)s, poly(glycolic acid)s, polycarbonates, polyesteramides, polyanydrides, poly(amino acids), polyorthoesters, poly(dioxanone)s, poly(alkylene alkylate)s, copolymers of polyethylene glycol and polyorthoester, polyurethanes, blends thereof, and copolymers thereof.

21. The pharmaceutical composition of claim 20 wherein the biocompatible, biodegradable polymer is a poly(lactide-co-glycolide).

22. The pharmaceutical composition of claim 14 wherein the bisphosphonate is alendronate, risendronate, pamidonate, etidronate, tiludronate or a combination thereof.

23. The pharmaceutical composition of claim 14, wherein the sustained release composition is in the form of microparticles.

24. The pharmaceutical composition of claim 14, wherein the biologically active agent is a protein, a peptide or a nucleic acid.

25. The pharmaceutical composition of claim 14, wherein the biologically active agent is a protein.

26. The pharmaceutical composition of claim 14, wherein the protein is erythropoietin.

14. A pharmaceutical composition comprising:
