EMA approves Hemlibra for routine prophylaxis in haemophilia A
Roche announced that the European Commission has approved Hemlibra (emicizumab) for routine prophylaxis of bleeding episodes in people with severe haemophilia A (congenital factor VIII deficiency, FVIII below 1%) without factor VIII inhibitors. Hemlibra can be used in all age groups, and can also now be used at multiple dosing options (once weekly, every two weeks, or every four weeks) for all indicated people with haemophilia A, including those with factor VIII inhibitors.
This approval is based on results from the pivotal HAVEN 3 and HAVEN 4 studies. In the HAVEN 3 study in people with haemophilia A without factor VIII inhibitors, Hemlibra prophylaxis led to statistically significant and clinically meaningful reductions in treated bleeds compared to no prophylaxis, and compared to prior treatment with factor VIII prophylaxis in a prospective intra-patient comparison. In the HAVEN 4 study in people with haemophilia A with and without factor VIII inhibitors, Hemlibra showed a clinically meaningful control of bleeding when dosed every four weeks.
Comment: On 4 October 2018, Hemlibra was approved by the US Food and Drug Administration (FDA) for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children, ages newborn and older, with haemophilia A without factor VIII inhibitors, following Priority Review. Hemlibra was also previously granted Breakthrough Therapy Designation by the FDA for haemophilia A without factor VIII inhibitors. Priority Review designation is granted to medicines that the FDA has determined to have the potential to provide significant improvements in the treatment, prevention or diagnosis of a serious disease.
