Female hemophilia A  patients and carriers have more frequent bleeding than males, yet a much smaller proportion receive replacement therapy to prevent or stop them, a U.S. study finds. The medical and pharmacy costs for women with hemophilia A or carriers were up to about 14 times lower…

More than 80% of the men with severe hemophilia A treated with the investigational gene therapy Roctavian (valoctocogene roxaparvovec) in the Phase 3 GENEr8-1 trial remained bleed-free two years later, and nearly all were off standard preventive therapies. These findings were among new data presented at the recent 15th Annual…

Data from ongoing Phase 3 clinical trials show that Genentech’s Hemlibra (emicizumab-kxwh) prophylaxis — or preventive treatment — greatly outperforms current standard-of-care therapies, leading to significant reductions in the number of bleeds in hemophilia A patients regardless of inhibitor status. Promising results from these pivotal studies may lead…

Children’s Hospital of Philadelphia (CHOP) has been awarded up to $38.9 million to advance the development of personalized gene‑editing therapies for four groups of rare genetic disorders — one of them hemophilia. The five-year award comes from the Advanced Research Projects Agency for Health (ARPA‑H) under its…

Weekly and monthly treatment with Mim8, an investigational antibody therapy, was seen to be better than on-demand or standard preventive treatments at reducing bleeding episodes in patients with hemophilia A, regardless of inhibitor status, who took part in a clinical trial. Top-line results from the global Phase 3…

A new, modified version of recombinant factor VIII (rFVIII), called rVIII-SingleChain, showed great efficacy and safety in treating bleeding events in children with severe hemophilia A. The study, “Safety, efficacy and pharmacokinetics of rVIII-SingleChain in children with severe hemophilia A: results of a multicenter clinical trial,” was published in…

Maintaining high concentrations of Adynovate in the blood of hemophilia A patients decreases the number of bleedings and enables more patients to stop having bleeds, according to the first results of a Phase 3b/4 study by Takeda.

Preventive treatment with Hemlibra (emicizumab) is safe and can effectively prevent bleeds in people with mild or moderate hemophilia A, according to an interim analysis of data from the HAVEN 6 clinical trial. Results will be presented at the annual meeting of the American Society of Hematology (ASH)…

Prophylactic (preventive) treatment with Hemlibra (emicizumab) safely and effectively lowers bleeding rates in children and adolescents with severe hemophilia A, according to a real-life study from Israel. The therapy’s effectiveness was independent of the presence of inhibitors (antibodies) against synthetic formulations of factor VIII (FVIII) — the missing…
