- First new medicine in over 20 years to treat people with haemophilia A with inhibitors in Europe
- Hemlibra demonstrated superior efficacy compared to prior treatment with bypassing agents in two phase III studies in adults, adolescents and children
- Once-weekly subcutaneous (under the skin) administration may help reduce treatment burden
Roche (SIX: RO, ROG; OTCQX: RHHBY) has announced that the European Commission has approved Hemlibra® (emicizumab) for routine prophylaxis of bleeding episodes in people with haemophilia A with factor VIII inhibitors. Hemlibra can be used in all age groups. Nearly one in three people with severe haemophilia A can develop inhibitors to factor VIII replacement therapies, putting them at greater risk of life-threatening bleeds or repeated bleeding episodes that can cause long-term joint damage.1 People with haemophilia A with inhibitors have a 70
“This approval is great news for people in Europe with haemophilia A with inhibitors to factor VIII. The development of inhibitors not only puts them at greater risk of frequent and severe bleeds, but also makes the disorder more difficult to manage, with limited treatment options available to date,” said Professor Johannes Oldenburg, Institute of Experimental Haematology and Transfusion Medicine, University of Bonn, Germany. “The bleed reduction and improvements in quality of life shown with Hemlibra compared to current treatments support its potential to advance the management of haemophilia A with inhibitors.”
“We’re delighted that the European Commission has approved Hemlibra, providing people with haemophilia A with inhibitors a new medicine for the first time in over 20 years,” said Sandra Horning, M.D., Roche’s Chief Medical Officer and Head of Global Product Development. “We believe Hemlibra has the potential to make a meaningful difference in the lives of people with haemophilia A with inhibitors, and are committed to working with EU member states to provide access to this important medicine as quickly as possible.”
The approval is based on two of the largest pivotal clinical studies in people with haemophilia A with inhibitors, in which Hemlibra demonstrated superior efficacy compared to prior treatment with bypassing agents (BPA) as prophylaxis or on-demand.
- In the HAVEN 1 study in adults and adolescents (12 years of age or older) with haemophilia A with inhibitors, Hemlibra prophylaxis showed a statistically significant reduction in treated bleeds of 87
- Interim results from the HAVEN 2 study in children younger than 12 years of age with haemophilia A with inhibitors showed that 87

These data also led to the approval of Hemlibra for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children with haemophilia A with factor VIII inhibitors by the US Food and Drug Administration (FDA) on 16 November 2017. Hemlibra was reviewed by the FDA under Priority Review and granted Breakthrough Therapy Designation by the FDA in people 12 years of age or older with haemophilia A with inhibitors in September 2015. Updated analyses from both the HAVEN 1 and HAVEN 2 studies were presented last December at the 2017 American Society of Hematology (ASH) Annual Meeting and showed that after longer follow-up, Hemlibra continued to substantially reduce bleeds in people with haemophilia A with inhibitors.
Hemlibra is being studied in a robust clinical development programme that includes two additional phase III studies, HAVEN 3 and HAVEN 4. Results from HAVEN 3 showed a statistically significant and clinically meaningful reduction in the number of treated bleeds over time in adults and adolescents (12 years of age or older) with haemophilia A without inhibitors who received Hemlibra prophylaxis every week or every two weeks, compared to those receiving no prophylaxis. Interim results from HAVEN 4 showed a clinically meaningful control of bleeding in adults and adolescents (12 years of age or older) with haemophilia A with or without inhibitors who received Hemlibra prophylaxis once every four weeks. Data from both these studies will be presented at an upcoming medical conference and submitted to health authorities around the world for approval consideration.
