Long-acting coagulation factors and methods of producing same
Polypeptides comprising at least one carboxy-terminal peptide (CTP) of chorionic gonadotrophin attached to the carboxy terminus but not to the amino terminus of a coagulation factor and polynucleotides encoding the same are disclosed. Pharmaceutical compositions comprising the polypeptides and polynucleotides of the invention and methods of using and producing same are also disclosed.
1. A method of treating hemophilia A in a subject, the method comprising administering a CTP-modified Factor VII (FVII) polypeptide to said subject, wherein said CTP-modified Factor VII (FVII) polypeptide consists of a coagulation Factor VII (FVII) polypeptide and three chorionic gonadotropin carboxy terminal peptides (CTPs) attached to the carboxy terminus of said coagulation FVII polypeptide, thereby treating said hemophilia A.
2. The method of claim 1 , wherein at least one CTP consists of the amino acid sequence selected from the group consisting of: SEQ ID NO: 1 and SEQ ID NO: 2.
3. The method of claim 1 , wherein at least one CTP is glycosylated.
4. The method of claim 1 , wherein at least one CTP is attached to said coagulation Factor VII polypeptide via a linker.
5. The method of claim 4 , wherein said linker is a peptide bond.
6. The method of claim 1 , wherein the sequence of said CTP-modified FVII polypeptide is selected from the group consisting of SEQ ID NO: 25 and SEQ ID NO: 46.
7. The method of claim 1 , wherein said coagulation FVII polypeptide is an activated coagulation FVII (FVIIa) polypeptide.
8. The method of claim 7 , wherein said activated coagulation FVII polypeptide is in the form of a disulfide-linked two chain heterodimer.
9. The method of claim 1 , wherein the subject is a human child.
10. The method of claim 1 , wherein said administering is via the subcutaneous route.
11. A method of treating hemophilia B in a subject, the method comprising the step of administering to the subject a CTP-modified Factor IX (FIX) polypeptide, wherein the CTP-modified Factor IX (FIX) polypeptide consists of a coagulation Factor IX (FIX) polypeptide and three chorionic gonadotrophin carboxy terminal peptides (CTPs) attached to the carboxy terminus of said coagulation FIX polypeptide, thereby treating said hemophilia B in said subject.
12. The method of claim 11 , wherein the sequence of said CTP-modified Factor IX (FIX) polypeptide is selected from the group consisting of SEQ ID NO: 31 and SEQ ID NO: 48.
13. The method of claim 11 , wherein at least one CTP consists of the amino acid sequence selected from the group consisting of: SEQ ID NO: 1 and SEQ ID NO: 2.
14. The method of claim 11 , wherein at least one CTP is glycosylated.
15. The method of claim 11 , wherein at least one CTP is truncated.
16. The method of claim 11 , wherein at least one CTP is attached to said coagulation FIX polypeptide via a linker.
17. The method of claim 16 , wherein said linker is a peptide bond.
18. The method of claim 11 , wherein said coagulation FIX polypeptide is an activated coagulation FIX (FIXa) polypeptide.
19. The method of claim 18 , wherein said activated coagulation FIX polypeptide is in the form of a disulfide-linked two chain heterodimer.
20. The method of claim 11 , wherein the subject is a human child.
21. The method of claim 11 , wherein said administering is via the subcutaneous route.
