Subcutaneous administration of coagulation factor VII
The invention relates to the use of a Factor VIIa for the manufacture of a medicament for treatment of a condition affectable by Factor VIIa, said medicament being for subcutaneous, intramuscular or intradermal administration, and to the use of a Factor VIIa for the manufacture of a medicament for treatment of a condition affectable by Factor VIIa, wherein said medicament, when administered subcutaneously, intradermally or intramuscularly, shows a prolonged biological half-life.
1. A method for treatment of a condition affectable by Factor VIIa (FVIIa), said method comprising administering subcutaneously to a mammal in need of such treatment an effective amount for treating said condition of a composition comprising modified FVIIa, wherein said modified FVIIa has substantially the same or better biological activity for blood coagulation as authentic FVIIa.
2. The method of claim 1 , wherein the condition is bleeding caused by a lack of, or defect in, coagulation factors VIII, IX, or VII, or by the presence of inhibitors against coagulation factors VIII, IX, or VII.
3. The method of claim 1 , wherein the condition is haemophilia A or B.
4. The method of claim 1 , wherein the modified FVIIa is modified recombinant human FVIIa.
5. The method of claim 1 , wherein the composition is a stable aqueous solution ready for administration.
6. The method of claim 1 , wherein the composition is lyophilized and reconstituted with a pharmaceutically acceptable vehicle suitable for injection prior to administration.
7. The method of claim 1 , wherein the composition is a stable aqueous solution ready for administration.
8. The method of claim 1 , wherein the modified FVII is selected from the group consisting of: [S52A]-FVIIa, [S60A]-FVIIa; Factor VIIa that has been proteolytically cleaved between residues 290 and 291; Factor VIIa that has been proteolytically cleaved between residues 315 and 316; [L305V]-FVIIa; [L305V/M306D/D309S]-FVIIa; [L305I]-FVIIa,[L305T]-FVIIa; [F374P]-FVIIa; [V158T/M298Q]-FVIIal; [V158D/E296V/M298Q]-FVIIa and [K337A]-FVIIa.
