NCIt definition : A recombinant form of human endogenous antihemophilic factor (rAHF) (coagulation factor
VIII) produced by recombinant DNA technology, in which the B-domain is deleted (BDDrFVIII),
that can be used to treat and control bleeding episodes in hemophilia A (congenital
factor-VIII deficiency). Upon administration, moroctocog alfa temporarily replaces
the missing coagulation factor VIII, which binds factor IXa. Factor X is then converted
to factor Xa. This facilitates the clotting cascade by converting prothrombin to thrombin,
and leads to the conversion of fibrinogen to fibrin, and thus clot formation. This
normalizes the activated partial thromboplastin time (aPTT) that is needed for effective
hemostasis. Patients with hemophilia A lack factor VIII, a protein needed for normal
clotting of the blood. B-domain has no known biological function.;
