Promising coagulation factor VIII bypassing strategies for patients with haemophilia A.

Haemophilia A is an X-linked recessive monogenic hereditary bleeding disorder caused by a deficiency or functional defect in coagulation factor VIII (FVIII). Typically, only 30% haemophilia A patients are treated with FVIII-specific products successfully. Therefore, other promising clotting factors and FVIII-bypassing factors exhibiting sufficient FVIII-independent activity, low immunogenicity and prolonged half-life are needed to conquer this malady.
