Abstract

Official abstract text for this publication.

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

Opening claim text (preview).

We claim: 1. A liquid ophthalmic formulation comprising: 40 mg/ml of a glycosylated vascular endothelial growth factor (VEGF) antagonist fusion protein comprising amino acids 27-457 of SEQ ID NO: 4; water; an organic co-solvent comprising polysorbate; and a stabilizing agent, wherein the liquid ophthalmic formulation has a pH of between 5.8 to 7.0, wherein the liquid ophthalmic formulation is suitable for intravitreal administration, wherein 90% or more of the weight of the VEGF antagonist fusion protein is not present as an aggregate, and wherein the VEGF antagonist fusion protein is at least 95% free of protein contaminants. 2. The liquid ophthalmic formulation of claim 1 , wherein the polysorbate is polysorbate 80, and wherein the stabilizing agent is sucrose and trehalose. 3. The liquid ophthalmic formulation of claim 2 , wherein the liquid ophthalmic formulation comprises 0.01% to 3% polysorbate 80. 4. The liquid ophthalmic formulation of claim 3 , wherein the liquid ophthalmic formulation comprises 0.03% to 0.1% polysorbate 80. 5. The liquid ophthalmic formulation of claim 4 , wherein the liquid ophthalmic formulation comprises 0.1% polysorbate 80. 6. The liquid ophthalmic formulation of claim 4 , wherein the liquid ophthalmic formulation comprises 0.03% polysorbate 80. 7. The liquid ophthalmic formulation of claim 2 , wherein the liquid ophthalmic formulation comprises 1.0% to 7.5% stabilizing agent. 8. The liquid ophthalmic formulation of claim 2 , wherein the liquid ophthalmic formulation comprises 1.0% to 7.5% sucrose. 9. The liquid ophthalmic formulation of claim 8 , wherein the liquid ophthalmic formulation comprises 5% sucrose. 10. The liquid ophthalmic formulation of claim 1 , wherein the liquid ophthalmic formulation has a pH of between 6.2 to 6.3. 11. A liquid ophthalmic formulation comprising: 40 mg/ml of a glycosylated vascular endothelial growth factor (VEGF) antagonist fusion protein comprising amino acids 27-457 of SEQ ID NO: 4; water; an organic co-solvent comprising polysorbate; and a stabilizing agent, wherein the liquid ophthalmic formulation has a pH of between 5.8 to 7.0, wherein the liquid ophthalmic formulation is suitable for intravitreal administration, wherein at least 98% of the VEGF antagonist fusion protein is present in native conformation following storage at 5° C. for two months as measured by size exclusion chromatography. 12. The liquid ophthalmic formulation of claim 11 , wherein the polysorbate is polysorbate 80, and wherein the stabilizing agent is sucrose and trehalose. 13. The liquid ophthalmic formulation of claim 12 , wherein the liquid ophthalmic formulation comprises 0.01% to 3% polysorbate 80. 14. The liquid ophthalmic formulation of claim 13 , wherein the liquid ophthalmic formulation comprises 0.03% to 0.1% polysorbate 80. 15. The liquid ophthalmic formulation of claim 14 , wherein the liquid ophthalmic formulation comprises 0.1% polysorbate 80. 16. The liquid ophthalmic formulation of claim 14 , wherein the liquid ophthalmic formulation comprises 0.03% polysorbate 80. 17. The liquid ophthalmic formulation of claim 16 , wherein at least 99% of the VEGF antagonist fusion protein is present in native conformation after 2 month storage at 5° C. as measured by size exclusion chromatography. 18. The liquid ophthalmic formulation of claim 12 , wherein the liquid ophthalmic formulation comprises 1.0% to 7.5% stabilizing agent. 19. The liquid ophthalmic formulation of claim 12 , wherein the liquid ophthalmic formulation comprises 1.0% to 7.5% sucrose. 20. The liquid ophthalmic formulation of claim 19 , wherein the liquid ophthalmic formulation comprises 5% sucrose. 21. The liquid ophthalmic formulation of claim 11 , wherein the liquid ophthalmic formulation has a pH of between 6.2 to 6.3. 22. A liquid ophthalmic formulation comprising: 40 mg/ml of a glycosylated vascular endothelial growth factor (VEGF) antagonist fusion protein comprising amino acids 27-457 of SEQ ID NO: 4; water; an organic co-solvent comprising polysorbate 80; and a stabilizing agent comprising sucrose and trehalose, wherein the liquid ophthalmic formulation has a pH of about 6.2 to 6.3, wherein the liquid ophthalmic formulation is suitable for intravitreal administration, wherein 90% or more of the weight of the VEGF antagonist fusion protein is not present as an aggregate, and wherein the VEGF antagonist fusion protein is at least 95% free of protein contaminants. 23. The liquid ophthalmic formulation of claim 22 , wherein the liquid ophthalmic formulation comprises 0.01% to 3% polysorbate 80. 24. The liquid ophthalmic formulation of claim 22 , wherein the liquid ophthalmic formulation comprises 1.0% to 7.5% stabilizing agent. 25. The liquid ophthalmic formulation of claim 22 , wherein the liquid ophthalmic formulation comprises 1.0% to 7.5% sucrose. 26.
