Abstract

The present disclosure pertains to compositions comprising anti-VEGF proteins and methods for producing such compositions.

Claims (29)

1. A prefilled syringe comprising aflibercept produced in chemically defined media (CDM), wherein said aflibercept includes oxidized variants that have at least one oxidized amino acid residue selected from the group consisting of tryptophan, histidine, and a combination thereof.

2. The prefilled syringe of claim 1 , wherein said oxidized amino acid residue is histidine.

3. The prefilled syringe of claim 1 , wherein said oxidized amino acid residue is tryptophan.

4. The prefilled syringe of claim 1 , wherein said aflibercept in said prefilled syringe has a BY value of at least 6 when the concentration of aflibercept is normalized to 5 g/L protein concentration.

5. The prefilled syringe of claim 1 , wherein said prefilled syringe contains between 40 mg/mL of said aflibercept to about 250 mg/mL of said aflibercept.

6. The prefilled syringe of claim 1 , wherein 90% of said aflibercept or more by weight is not present as an aggregate.

7. The prefilled syringe of claim 1 , wherein said prefilled syringe is glass.

8. The prefilled syringe of claim 1 , wherein said prefilled syringe is tinted.

9. The prefilled syringe of claim 1 , wherein said prefilled syringe is an auto injector.

10. The prefilled syringe of claim 1 , wherein said aflibercept loaded into said prefilled syringe is formulated with a pH between 5.5 and 7.5.

11. The prefilled syringe of claim 1 , wherein the aflibercept is formulated with one or more pharmaceutically acceptable excipients.

12. The prefilled syringe of claim 1 , wherein said aflibercept in said prefilled syringe has a b* value between 0.4 and 5, when the concentration of said aflibercept is normalized to 5.0 g/L.

13. The prefilled syringe of claim 1 , wherein said aflibercept in said prefilled syringe has a b* value between 0.5 and 5, when the concentration of said aflibercept is normalized to 5.0 g/L.

14. The prefilled syringe of claim 1 , wherein said aflibercept in said prefilled syringe has between 0.1% and 1% oxidized amino acid residue selected from the group consisting of tryptophan, histidine, and a combination thereof.

15. The prefilled syringe of claim 1 , wherein said prefilled syringe has about 2 mg/0.05 mL of aflibercept.

16. The prefilled syringe of claim 9 , wherein said prefilled auto injector syringe has between 40 mg/mL to about 250 mg/mL of said aflibercept.

17. The prefilled syringe of claim 2 , wherein said aflibercept includes oxidized histidine selected from the group consisting of His86, His110, His145, His209, His95, His19, His203 and a combination thereof.

18. The prefilled syringe of claim 3 , wherein said aflibercept includes oxidized tryptophan selected from the group consisting of Trp58, Trp138 and a combination thereof.

19. The prefilled syringe of claim 1 , wherein said aflibercept includes oxidized tyrosine at Tyr64.

20. The prefilled syringe of claim 1 , wherein said aflibercept includes oxidized phenylalanine selected from the group consisting of Phe44, Phe166 and a combination thereof.

21. A prefilled syringe comprising aflibercept having a BY value of at least 5 when the concentration of aflibercept is normalized to 5 g/L protein concentration, wherein said aflibercept includes oxidized variants that have at least one oxidized amino acid residue selected from the group consisting of tryptophan, histidine, and a combination thereof.

22. The prefilled syringe of claim 21 wherein said oxidized amino acid residue is histidine selected from the group consisting of His86, His110, His145, His209, His95, His19, His203 and a combination thereof.

23. The prefilled syringe of claim 21 wherein said oxidized amino acid residue is tryptophan selected from the group consisting of Trp58, Trp138 and a combination thereof.

24. The prefilled syringe of claim 21 , wherein 90% of said aflibercept or more of the weight is not present as an aggregate.

25. The prefilled syringe of claim 21 , wherein said prefilled syringe is glass.

26. The prefilled syringe of claim 21 , wherein said prefilled syringe is tinted.

27. The prefilled syringe of claim 21 , wherein said prefilled syringe is an auto injector.

28. The prefilled syringe of claim 21 , wherein said aflibercept loaded into said prefilled syringe is formulated with a pH between 5.5 and 7.5.

29. The prefilled syringe of claim 21 , wherein said aflibercept in said prefilled syringe has between 0.1% and 1% oxidized amino acid residue selected from the group consisting of tryptophan, histidine, and a combination thereof.
