Use of factor VIIa analogues with increased activity

1 . A method for the treatment of bleeding episodes in a subject with severe bleedings, the method comprising administering to a subject in need of said treatment an effective amount for said treatment of a Factor VII polypeptide having increased activity compared to wild-type Factor VIIa.

2 . A method according to claim 1 , wherein the subject with severe bleeding exhibits acidosis with a blood pH lower than 7.45.

3 . A method according to claim 1 , wherein the subject with severe bleeding exhibits a pre-treatment haemoglobin level at least about 4 g/dl lower than the normal level for said subject.

4 . A method according to claim 1 , wherein the subject with severe bleeding exhibits hypothermia with a temperature below 37 degree Celsius,

5 . A method according to claim 1 , wherein the ratio between the activity of said Factor VII polypeptide and the activity of the wild-type Factor VIIa polypeptide shown in SEQ ID NO:1 is at least about 1.25.

6 . A method according to claim 5 , wherein said Factor VII polypeptide having increased activity compared to wild-type Factor VIIa is V158D/E296V/M298Q-FVIIa.

7 . A method according to claim 1 , wherein said effective amount comprises not more than about 100 μg/kg of a Factor VII polypeptide.

8 . A method according to claim 7 , wherein said effective amount comprises not more than about 20 μg/kg of a Factor VII polypeptide.

9 . A method according to claim 8 , wherein said effective amount comprises not more than about 5 μg/kg of a Factor VII polypeptide.

10 . A method according to claim 1 , further comprising administering to the subject a second coagulation agent in an amount that augments said treating by said Factor VII polypeptide having increased activity compared to wild-type Factor VIIa.

11 . A method according to claim 10 , wherein said second coagulation agent is selected from the group consisting of a coagulation factor and an antifibrinolytic agent.

12 . A method according to claim 11 , wherein said coagulation agent is selected from the group consisting of Factor V, Factor VIII, Factor IX, Factor X, Factor XI, Factor XIII, Fibrinogen, thrombin, TAFI, PAI-, aprotinin, epsilon-aminocaproic acid, tranexamic acid, an antithrombotic treatment, and transfusions with one or more of platelet, RBC, FFP, and oxygen carriers.

13 . A method for the treatment of bleeding episodes in a subject with severe bleedings in a majority of subjects with severe bleedings, said method comprising (i) administering to a group of subjects with a severely bleeding an effective amount for said treatment of Factor VII polypeptide having increased activity compared to wild-type Factor VIIa; and (ii) observing an improvement in one or more clinical parameters of said bleeding episode among said group of subjects relative to the level of said clinical parameters that would have been expected in the same group of subjects who had not received said Factor VII polypeptide having increased activity compared to wild-type Factor VIIa.

14 . A kit of parts for treatment of bleeding episodes in a subject with sever bleeding, comprising

(i) A medicament comprising a Factor VII polypeptide having increased activity compared to wild-type Factor VIIa; and

(ii) Instructions for Use describing that:

a. A first dose containing no more than about 100 μg/kg of a Factor VII polypeptide having increased activity compared to wild-type Factor VIIa, should be administered at the start of treatment;

b. Optionally, a second dose containing no more than about 100 μg/kg Factor VII polypeptide having increased activity compared to wild-type Factor VIIa should be administered one to 24 hours after the start of treatment.
