Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the EU Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Hemlibra®(emicizumab) for routine prophylaxis of bleeding episodes in adults and children with severe haemophilia A (congenital factor VIII deficiency, FVIII <1%) without factor VIII inhibitors, wie www.roche.com berichtet.

The CHMP has also recommended that Hemlibra can 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.The positive CHMP opinion 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. Based on this opinion, a final decision regarding the approval of Hemlibra for people without factor VIII inhibitors is expected from the European Commission in the near future.“Current prophylactic treatments for haemophilia A can require several intravenous infusions per week, and even then, some people may still bleed,” said Víctor Jiménez Yuste, Associate Professor of Haematology at Autónoma University and Head of the Haematology Department at La Paz University Hospital in Madrid, Spain.

“With three subcutaneous dosing options, which provided effective bleed control in pivotal clinical trials, Hemlibra has the potential to make a meaningful difference in the lives of people with haemophilia A.”“Hemlibra is highly anticipated as the first new class of treatment for people with haemophilia A without inhibitors in nearly 20 years,” said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. “We welcome today’s positive CHMP opinion, which brings us one step closer to providing Hemlibra to people living with severe haemophilia A without factor VIII inhibitors in the EU.

We will continue to work with the EMA and local health providers to make Hemlibra available to all those living with haemophilia A who may benefit from this therapy.”In the phase III HAVEN 3 study, adults and adolescents aged 12 years or older with haemophilia A without factor VIII inhibitors who received Hemlibra prophylaxis once weekly (n=36) or every two weeks (n=35) experienced a 96% (rate ratio [RR]=0.04; p<0.0001) and 97% (RR= 0.03; p<0.0001) reduction in treated bleeds, respectively, compared to those who received no prophylaxis (n=18). Hemlibra is the first medicine to significantly reduce treated bleeds compared to prior factor VIII prophylaxis, the standard of care for people with haemophilia A without factor VIII inhibitors, as demonstrated by a statistically significant reduction of 68% (RR=0.32; p<0.0001) in treated bleeds in an intra-patient comparison (n=48) of people who previously received factor VIII prophylaxis in a prospective non-interventional study and switched to Hemlibra prophylaxis.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.

Breakthrough Therapy Designation is designed to expedite the development and review of medicines intended to treat a serious condition with preliminary evidence that indicates they may demonstrate substantial improvement over existing therapies. Submissions to other regulatory authorities around the world are ongoing.HAVEN 3 is a randomised, multicentre, open-label, phase III study evaluating the efficacy, safety and pharmacokinetics of Hemlibra prophylaxis versus no prophylaxis (episodic/on-demand factor VIII treatment) in people with haemophilia A without factor VIII inhibitors.

The study included 152 patients with haemophilia A (12 years of age or older) who were previously treated with factor VIII therapy either on-demand or as prophylaxis. Patients previously treated with on-demand factor VIII were randomised in a 2:2:1 fashion to receive subcutaneous Hemlibra prophylaxis at 3 mg/kg/wk for four weeks, followed by 1.5 mg/kg/wk for at least 24 weeks (Arm A), subcutaneous Hemlibra prophylaxis at 3 mg/kg/wk for four weeks, followed by 3 mg/kg/2wks (Arm B) for at least 24 weeks or no prophylaxis (Arm C) for at least 24 weeks.Patients previously treated with factor VIII prophylaxis received subcutaneous Hemlibra prophylaxis at 3 mg/kg/wk for four weeks, followed by 1.5 mg/kg/wk until the end of study (Arm D).

Episodic treatment of breakthrough bleeds with factor VIII therapy was allowed per protocol.HAVEN 3 met its primary endpoint and key secondary endpoints. Data from the study showed:HAVEN 4 is a single-arm, multicentre, open-label, phase III study evaluating the efficacy, safety and pharmacokinetics (PK) of subcutaneous administration of Hemlibra dosed every four weeks.

The study included 48 patients (12 years of age or older) with haemophilia A with or without factor VIII inhibitors who were previously treated with either factor VIII or bypassing agents, on-demand or as prophylaxis. The study was conducted in two parts: a PK run-in and an expansion cohort.

All patients in the PK run-in (n=7) were previously treated on-demand and received subcutaneous Hemlibra at 6 mg/kg to fully characterise the PK profile after a single dose during four weeks, followed by 6 mg/kg every four weeks for at least 24 weeks. Patients in the expansion cohort (n=41), patients with haemophilia A with factor VIII inhibitors (n=5) and without factor VIII inhibitors (n=36), received subcutaneous Hemlibra prophylaxis at 3 mg/kg/wk for four weeks, followed by 6 mg/kg every four weeks for at least 24 weeks.

Episodic treatment of breakthrough bleeds with factor VIII therapy or bypassing agents, depending on a patient’s factor VIII inhibitor status, was allowed per study protocol.Hemlibra is a bispecific factor IXa- and factor X-directed antibody. It is designed to bring together factor IXa and factor X, proteins required to activate 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. 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 US Food and Drug Administration.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 320,000 people worldwide,[1, 2] approximately 50-60% of whom have a severe form of the disorder.[3] 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 disorder, people with haemophilia A can bleed frequently, especially into their joints or muscles.[1] 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.[4] A serious complication of treatment is the development of inhibitors to factor VIII replacement therapies.[5] Inhibitors are antibodies developed by the body’s immune system that bind to and block the efficacy of replacement factor VIII,[6] making it difficult, if not impossible to obtain a level of factor VIII sufficient to control bleeding.For more than 20 years, Roche has been developing medicines that redefine treatment in haematology. Today, we are investing more than ever in our effort to bring innovative treatment options to people with diseases of the blood.
