​​​​​​ReFacto AF® (moroctocog alfa) is indicated for the treatment and prophylaxis of bleeding in patients with haemophilia A (congenital factor VIII deficiency). ReFacto AF® is appropriate for use in adults and children of all ages, including newborns. ReFacto AF® does not contain von Willebrand factor, and hence is not indicated in von Willebrand's disease.1

How ReFacto AF® works

ReFacto AF® (moroctocog alfa AF-CC) contains B-domain deleted recombinant coagulation factor VIII, and has functional characteristics comparable to those of endogenous factor VIII. As factor VIII activity is greatly reduced in patients with haemophilia A, replacement therapy is necessary.1​​​​

How does ReFacto AF® replace factor VIII?

Haemophilia A is a sex-linked hereditary coagulopathy resulting from decreased factor VIII:C, that causes profuse bleeding into joints, muscles or internal organs, either spontaneously or as a result of trauma. Replacement therapy increases the plasma factor VIII levels, temporarily correcting the factor deficiency and, consequently, the bleeding tendencies.1

When infused into a patient with haemophilia A, factor VIII binds to the circulating von Willebrand factor. Activated factor VIII acts as a cofactor for activated factor IX, accelerating the conversion of factor X to activated factor X. Activated factor X converts prothrombin into thrombin. Thrombin then converts fibrinogen into fibrin, and a clot is formed.1
