- Hemlibra, already approved for severe haemophilia A in the EU, will now also provide an effective and convenient prophylactic treatment option for people with moderate haemophilia A
- Moderate haemophilia A can have a significant impact on the lives of people affected, with only 15% living a bleed-free life1
- The approval is based on the HAVEN 6 results, where Hemlibra demonstrated effective bleed control and a favourable safety profile in people with moderate haemophilia A without inhibitors2
Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the European Commission approved the expansion of the Hemlibra® (emicizumab) European Union (EU) marketing authorisation. The label will now include the routine prophylaxis of bleeding episodes in people with haemophilia A (congenital factor VIII deficiency) without factor VIII inhibitors, who have moderate disease (FVIII ≥1% and ≤ 5%) with a severe bleeding phenotype.3 Haemophilia A affects around 900,000 people worldwide,4,5 approximately 14% of whom have a moderate form of the disease.6
“We welcome the European Commission’s decision to approve Hemlibra also for people with moderate haemophilia A in the EU, since even moderate disease can produce bleeds that cause irreversible joint damage and impact quality of life,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “As its benefit expands to broader populations, we remain committed to determining how Hemlibra might help even more people with haemophilia A to live a bleed-free life.”
While the treatment and care of people with severe haemophilia A are well-established, there is less information and guidance on prophylaxis for moderate haemophilia A.7 Additionally, the severity of haemophilia A, traditionally measured by an individual’s factor VIII levels, is not always reflective of bleeding behaviour. Many people with moderate haemophilia A may not be receiving prophylactic treatments and could have a worsened clinical burden. Approximately 85% of people with moderate haemophilia A have bleeds within a given year and one in three have long-term joint problems, many of which require surgery and impact quality of life.1,7,8
This approval is based on the results of the phase III HAVEN 6 trial, in which Hemlibra demonstrated effective bleed control and a favourable safety profile in people with non-severe haemophilia A without factor VIII inhibitors, where prophylaxis was clinically indicated.2 The decision was also based on real world data. This label expansion will provide an effective and convenient prophylactic treatment option with a favourable safety profile for people in the EU with moderate haemophilia A with a severe bleeding phenotype.
Hemlibra is approved as a prophylactic treatment option for people with haemophilia A with factor VIII inhibitors in more than 110 countries and for people without factor VIII inhibitors in more than 100 countries worldwide. It has been studied in one of the largest clinical trial programmes in people with haemophilia A with and without factor VIII inhibitors, including eight phase III studies.
About HAVEN 6
HAVEN 6 is a phase III clinical study designed to evaluate the safety, efficacy, pharmacokinetics and pharmacodynamics of Hemlibra in people with non-severe haemophilia A without factor VIII inhibitors. Data from the primary analysis of HAVEN 6 was presented at the 30th International Society on Thrombosis and Haemostasis (ISTH) Annual Congress, on 11 July 2022.2 The analysis included data from 72 participants, including three women, 51 (70.8%) of whom had moderate haemophilia A without factor VIII inhibitors. The data indicate that Hemlibra has effective bleed control and a favourable safety profile in people with non-severe haemophilia A without factor VIII inhibitors, with no new safety signals identified. Hemlibra achieved clinically meaningful bleed control, with 66.7% of participants experiencing no bleeds that required treatment, 81.9% experiencing no spontaneous bleeds that required treatment, and 88.9% experiencing no joint bleeds that required treatment. Model-based annualised bleed rates (ABR) remained low throughout the evaluation period at 0.9 (95% CI: 0.55-1.52).2
About Hemlibra® (emicizumab)
Hemlibra is a bispecific factor IXa- and factor X-directed antibody. It is designed to bring together factor IXa and factor X, proteins involved in the natural coagulation cascade, and restore the blood clotting process for people with haemophilia A. Hemlibra is a prophylactic (preventative) treatment that can be administered by an injection of a ready-to-use solution under the skin (subcutaneously) once-weekly, every two weeks, or every four weeks (after an initial once-weekly dose for the first four weeks). Hemlibra was created by Chugai Pharmaceutical Co., Ltd. and is being co-developed globally by Chugai, Roche and Genentech. It is marketed in the United States by Genentech as Hemlibra (emicizumab-kxwh), with kxwh as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration.9
About haemophilia A
Haemophilia A is an inherited, serious disorder in which a person’s blood does not clot properly, leading to uncontrolled and often spontaneous bleeding. Haemophilia A affects around 900,000 people worldwide,4,5 approximately 14% of whom have a moderate form of the disorder.6 However, the severity of haemophilia A is not always reflective of bleeding behaviour, as some people with non-severe haemophilia may experience symptoms similar to those with severe haemophilia and warrant prophylaxis.8 All severities of haemophilia A can significantly reduce the quality of life for people affected, as well as their family and caregivers. People with haemophilia A either lack or do not have enough of a clotting protein called factor VIII. In a healthy person, when a bleed occurs, factor VIII brings together the clotting factors IXa and X, which is a critical step in the formation of a blood clot to help stop bleeding. Depending on the severity of their symptoms, people with haemophilia A can bleed frequently, especially into their joints or muscles.6 These bleeds can present a significant health concern as they often cause pain and can lead to chronic swelling, deformity, reduced mobility and long-term joint damage.10 A serious complication of treatment is the development of inhibitors to factor VIII replacement therapies. Inhibitors are antibodies developed by the body’s immune system that bind to and block the efficacy of replacement factor VIII, making it difficult, if not impossible, to obtain a level of factor VIII sufficient to control bleeding.11
