Novo Nordisk announced that the Food and Drug Administration (FDA) has approved Esperoct (turoctocog alfa pegol, N8-GP) for the treatment of patients with hemophilia A (congenital factor VIII deficiency) for routine prophylaxis to reduce the frequency of bleeding episodes, on-demand treatment and control of bleeding episodes and perioperative management of bleeding.

Esperoct is an extended half-life factor VIII molecule indicated for replacement therapy. Compared to standard half-life factor VIII products, Esperoct provides a 1.6-fold half-life prolongation in adults/adolescents and a 1.9-fold half-life prolongation in children. 

Esperoct was evaluated in 5 prospective, multicenter trials (N=270) of previously treated patients with severe hemophilia A and >5 years of clinical exposure with no history of inhibitors. Data included 80,425 exposure days corresponding to 889 patient-years of treatment. Trial results showed that in adults and adolescents, Esperoct, dosed every 4 days, provided effective prophylaxis and was associated with a median annual bleed rate of 1.18. In addition, efficacy was established in the treatment and control of bleeding episodes and perioperative management.

Esperoct was well-tolerated across all studies and age groups; the safety profile was found to be comparable to that seen with other long-acting factor VIII products.

Esperoct is not expected to be available in the US until 2020.
