Most people with moderate or mild hemophilia A who received preventive treatment with Hemlibra (emicizumab) in the HAVEN 6 clinical trial had no bleeds requiring treatment over a median follow-up of over a year, new data show. The findings were presented at the 30th International Society on Thrombosis and…

Bleeding episodes in people with severe hemophilia A receiving prophylactic (preventive) treatment have the potential to impair patients’ health-related quality of life, according to data from a survey conducted in Europe. Even a single bleed was linked to marked medication-related and non-related health costs. In fact, in terms of…

Patients with hemophilia A who switched to Kovaltry (octocog alfa) — a recombinant, or lab-made, factor VIII (rFVIII) replacement therapy given at home — had significantly fewer bleeds than with their previous standard half-life replacement therapies, a real-world study in Italy reported. The therapy also reduced the frequency…

People in France with severe hemophilia A who switched to Elocta (efmoroctocog alfa) — an extended half-life replacement therapy — had fewer infusions and a reduced rate of joint bleeds, a real-world study reports. Notably, those who switched to Elocta had a higher bleeding rate, including joint bleeds,…

Nearly one-third of people with hemophilia B have antibodies against a subtype of an adeno-associated virus (AAV) — called AAV6 — that is used as an experimental gene therapy carrier, a U.K. study found. Because such antibodies could render the treatment that the carrier holds ineffective, these patients would…

Treatment with an antibody designed to specifically block the anti-blood clotting, or anticoagulant, activity of an enzyme called activated protein C (APC) significantly reduced bleeding and related mortality in hemophilia A and hemophilia B mouse models, a study shows. The antibody, called HAPC1573, was also found to improve…

European authorities have recommended conditional marketing authorization for Roctavian (valoctocogene roxaparvovec), BioMarin Pharmaceutical’s one-time gene therapy for adults with severe hemophilia A. This positive decision, from the Committee for Medicinal Products for Human Use (CHMP), makes Roctavian the first gene therapy for hemophilia A to be recommended for European…

An innovative gel containing two snake venom proteins known to help blood clotting, rapidly and effectively forms stable clots and reduces bleeding even in the presence of a blood-clotting disorder, as is the case in hemophilia, a preclinical study shows. The gel, which transitions to a liquid form below…

Japan’s Ministry of Health, Labor and Welfare has extended Hemlibra (emicizumab)’s approval to include routine prophylaxis to prevent or lower the frequency of bleeds in people with acquired hemophilia A. Its decision comes seven months after Hemlibra’s maker, Chugai Pharmaceutical, applied for extended use. Hemlibra was previously approved in…

ASC Therapeutics has joined forces with Charles River to scale the manufacturing of ASC618, its second-generation virus-based gene therapy for hemophilia A. The agreement expands upon their current collaboration, begun in 2019 that focused on achieving Good Manufacturing Practice (GMP)-virus manufacturing and establishing processes for adeno-associated virus (AAV) production…
