Abstract

Ophthalmic formulations of a vascular endothelial growth factor (VEGF)-specific fusion protein antagonist are provided suitable for intravitreal administration to the eye. The ophthalmic formulations include a stable liquid formulation and a lyophilizable formulation. Preferably, the protein antagonist has an amino acid sequence of SEQ ID NO:4.

First claim

We claim:

a buffer, and
a stabilizing agent,
wherein said VEGF antagonist fusion protein is glycosylated and comprises amino acids 27-457 of SEQ ID NO:4; and
wherein at least 98% of the VEGF antagonist is present in native conformation following storage at 5° C. for two months as measured by size exclusion chromatography.

2. The vial of claim 1 , wherein the concentration of said VEGF antagonist fusion protein is 40 mg/ml, and wherein said organic co-solvent comprises polysorbate.

3. The vial of claim 2 , wherein said organic co-solvent comprises 0.01% to 3% polysorbate.

4. The vial of claim 2 , wherein said organic co-solvent comprises about 0.03% to about 0.1% polysorbate 20.

5. The vial of claim 2 , wherein said organic co-solvent comprises 0.01% to 3% polysorbate 20.

6. The vial of claim 5 , wherein said buffer comprises a phosphate buffer.

10. The vial of claim 5 , wherein said stabilizing agent comprises a sugar.

11. The vial of claim 10 , wherein said sugar is selected from the group consisting of sucrose, sorbitol, glycerol, trehalose, and mannitol.

12. The vial of claim 5 , wherein said stabilizing agent comprises 1.0-7.5% of sucrose.

13. The vial of claim 5 , wherein said formulation further comprises a tonicity agent.

14. The vial of claim 5 , wherein said VEGF antagonist fusion protein is glycosylated at asparagine residues corresponding to asparagine residues 62, 94, 149, 222 and 308 of SEQ ID NO: 4.

15. The vial of claim 5 , wherein said formulation is capable of providing a turbidity of 0.01 or lower at OD 405 after 2 month storage at 5° C.

16. The vial of claim 5 , wherein at least 99% of said VEGF antagonist fusion protein is present in native conformation after 2 month storage at 5° C. as measured by size exclusion chromatography.

17. The vial of claim 5 , wherein at least 98% of said VEGF antagonist fusion protein is present in native conformation following storage at 5° C. for 24 months as measured by size exclusion chromatography.

18. The vial of claim 5 , wherein said formulation does not contain phosphate.

19. The vial of claim 5 , wherein said formulation does not contain trehalose.

20. The vial of claim 5 , wherein said stabilizing agent comprises 1.0-10% of sucrose.

21. The vial of claim 20 , wherein said formulation further comprises a tonicity agent.

22. The vial of claim 20 , wherein said VEGF antagonist fusion protein is glycosylated at asparagine residues corresponding to asparagine residues 62, 94, 149, 222 and 308 of SEQ ID NO: 4.

23. The vial of claim 20 , wherein said formulation is capable of providing a turbidity of 0.01 or lower at OD 405 after 2 month storage at 5° C.

24. The vial of claim 20 , wherein at least 99% of said VEGF antagonist fusion protein is present in native conformation after 2 month storage at 5° C. as measured by size exclusion chromatography.

25. The vial of claim 20 , wherein at least 98% of said VEGF antagonist fusion protein is present in native conformation following storage at 5° C. for 24 months as measured by size exclusion chromatography.
