Adverse event reporting information can be found at the bottom of the page.

​​​​​​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

Clinical efficacy​​​​​​​​​​​​​​

​​​​​​​Reliable efficacy when you and your patients need it most.2,3​​​​​​​

Prophylactic treatment in PTPs

Reduction in annual bleed rate (ABR) vs. on-demand in previously treated patients (PTPs). ReFacto AF® prophylaxis is more effective at preventing bleeds than on-demand treatment, with an 85% reduction of bleeds per year (median ABR: 3.4; n=154) achieved with prophylactic treatment.4*    

* ReFacto AF® is manufactured using the same cell line as ReFacto®5 and is bioequivalent to ReFacto® and pharmacokinetically equivalent to a full-length recombinant factor VIII (FLrFVIII) comparator,1 so it is expected to behave in the same way.  


On-demand treatment in PTPs

of 10,882 bleeding episodes were treated effectively with only 1 infusion (n=113).2,3

On-demand treatment in previously untreated patients (PUPs)    

of 2,715 bleeding episodes were treated effectively with only 1 infusion (n=101).2,3  


of infusions administered were rated as excellent or good by the surgeon and treating physician (38 patients; 48 surgical procedures; 496 infusions during or after surgery).2†  

†​​​​​​ Excellent rating: achievement of comparable haemostasis to that expected after similar surgery in a non-haemophilic patient. Good rating: prolonged time to haemostasis with somewhat increased bleeding compared with that expected after similar surgery in a non-haemophilic patient.2
