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.
Opening claim text (preview).
We claim: 1. A formulation comprising: (a) 1-100 mg/mL of a VEGF-specific fusion protein antagonist; (b) 5-40 mM of a buffer; (c) 0.01-5% of an organic co-solvent; and (d) a stabilizer or 30-150 mM of a tonicity agent, wherein the VEGF-specific fusion protein antagonist represents at least 90% of the total weight of protein in the composition, at least 90% of the total weight of the VEGF-specific fusion protein antagonist is not present as an aggregate, and the VEGF-specific fusion protein antagonist comprises an Ig domain 2 of human VEGF receptor 1, an Ig domain 3 of human VEGF receptor 2, and a multimerizing component. 2. The formulation of claim 1 , wherein the VEGF-specific fusion protein antagonist represents at least 95% of the total weight of protein in the composition. 3. The formulation of claim 2 , wherein the VEGF-specific fusion protein antagonist represents at least 99% of the total weight of protein in the composition. 4. The formulation of claim 1 , wherein the VEGF-specific fusion protein antagonist is present at a concentration of about 10 to about 80 mg/ml. 5. The formulation of claim 4 , where the VEGF-specific fusion protein antagonist is present at a concentration of about 10, about 20, about 30, about 40, about 50, about 60, about 70, or about 80 mg/ml. 6. The formulation of claim 1 , wherein the buffer comprises a phosphate buffer. 7. The formulation of claim 6 , wherein the buffer comprises sodium phosphate present at a concentration of 10 mM. 8. The formulation of claim 1 , wherein the pH of the composition is about pH 5.8-7.0. 9. The formulation of claim 1 , wherein the pH is about pH 6.2-6.3. 10. The formulation of claim 1 , wherein the pH is about pH 6.0. 11. The formulation of claim 1 , wherein the organic co-solvent comprises one or more of polysorbate 20, polysorbate 80, polyethylene glycol (PEG) 3350, and propylene glycol. 12. The formulation of claim 11 , wherein the organic co-solvent is present at a concentration of 0.01-3%. 13. The formulation of claim 12 , wherein the organic co-solvent is PEG 3350 or polypropylene glycol at a concentration of about 3%. 14. The formulation of claim 1 , wherein the organic co-solvent is present at a concentration of 0.01-0.15%. 15. The formulation of claim 14 , wherein the organic co-solvent is polysorbate 80 or polysorbate 20 present at a concentration of 0.015%, 0.03% or 0.1%. 16. The formulation of claim 1 , wherein the tonicity agent comprises sodium chloride or potassium chloride. 17. The formulation of claim 16 , wherein the tonicity agent comprises sodium chloride present at a concentration of 20-135 mM. 18. The formulation of claim 17 , wherein the sodium chloride is present at a concentration of 20 mM, 40 mM, 50 mM, 100 mM, or 135 mM. 19. The formulation of claim 1 , comprising a stabilizer comprising trehalose or sucrose. 20. The formulation of claim 19 , wherein the stabilizer comprises sucrose. 21. The formulation of claim 20 , wherein the sucrose is present at a concentration of 5%. 22. The formulation of claim 1 , wherein the VEGF-specific fusion protein antagonist does not comprise amino acids 1-26 of SEQ ID NO:4. 23. The formulation of claim 1 , wherein the VEGF-specific fusion protein antagonist is a dimer. 24. The formulation of claim 1 , wherein the VEGF-specific fusion protein antagonist is expressed in a Chinese hamster ovary (CHO) cell. 25. The formulation of claim 1 , wherein the VEGF-specific fusion protein antagonist comprises glycosylated Asn residues corresponding to Asn residues at positions 62, 94, 149, 222, and 308 of SEQ ID NO:4. 26. A vial containing a formulation comprising: (a) 1-100 mg/mL of a VEGF-specific fusion protein antagonist; (b) 5-40 mM of a buffer; (c) 0.01-5% of an organic co-solvent; (d) a stabilizer or 30-150 mM of a tonicity agent, wherein the VEGF-specific fusion protein antagonist represents at least 90% of the total weight of protein in the composition, at least 90% of the total weight of the VEGF-specific fusion protein antagonist is not present as an aggregate, and the VEGF-specific fusion protein antagonist comprises an Ig domain 2 of human VEGF receptor 1, an Ig domain 3 of a human VEGF receptor 2, and a multimerizing component. 27. The vial of claim 26 , wherein the composition is stored under an inert gas, wherein the inert gas is nitrogen, helium or argon. 28. The vial of claim 27 , wherein the vial is stored at 5° C. 29. The vial of claim 28 , wherein the VEGF-specific fusion protein antagonist does not comprise amino acids 1-26 of SEQ ID NO:4.
