Turoctocog alfa is safe for the treatment of Indian patients with hemophilia A: Guardian 10 trial results

BACKGROUND: Hemophilia A is an X chromosome-linked bleeding disorder caused by the deficiency of coagulation factor VIII (FVIII). The majority of the Indian population with hemophilia A use plasma-derived clotting factors and, in some instances, fresh frozen plasma and cryoprecipitate. Safer and more efficient treatment options are needed for this group of patients. OBJECTIVES: To assess the safety of turoctocog alfa, a third-generation recombinant FVIII molecule, for the treatment and prophylaxis of bleeding episodes in previously treated Indian patients with moderate or severe hemophilia A. PATIENTS/METHODS: This single-country, multicenter, open-label, nonrandomized trial enrolled 60 patients who received prophylactic treatment with turoctocog alfa for 8 weeks, which corresponded to a minimum of 20 exposure days. Confirmed development of FVIII inhibitors during the 8-week treatment period was evaluated. Other assessments included frequencies of adverse drug reactions (ARs), serious adverse reactions, drug-related allergic reactions, and infusion reactions during the 12-week period after the first treatment; hemostatic effect of turoctocog alfa for the treatment of bleeding episodes; and total annualized dose of turoctocog alfa administered during the 8-week treatment period. RESULTS: No incidence of FVIII inhibitors was detected. No safety concerns such as ARs, serious ARs, or drug-related allergic reactions were noted. The hemostatic success rate for the treatment of bleeding episodes with turoctocog alfa was 81.6%. CONCLUSIONS: The trial results demonstrated that turoctocog alfa is a safe treatment option for the prophylaxis and treatment of bleeding episodes in previously treated adolescent and adult patients with hemophilia A in the Indian population.
