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…

An 87-year old woman with acquired hemophilia A (AHA) showed no adverse events or major bleeding events after starting on Hemlibra (emicizumab). The findings suggest that Hemlibra may be a better option for bleeding prevention in AHA patients than bypassing agents, the team said. The study, “…

The first participant has been dosed in a Phase 1/2 clinical trial evaluating marzeptacog alfa activated (MarzAA) to treat bleeding episodes in patients with factor VII (FVII) deficiency, Glanzmann thrombasthenia, and hemophilia A with inhibitors receiving treatment with…

For boys and men with moderate to severe hemophilia, switching to extended half-life (EHL) products is linked to a reduced number of infusions and a sustained low rate of bleeds, according to a  real-life, multi-center study in Canada. Notably, a significant drop in the annualized bleeding rate (ABR)…

Successful immune tolerance induction (ITI) — a type of treatment that aims to re-educate the immune system to prevent the formation of inhibitors, or neutralizing antibodies targeting clotting factors — was associated with lower treatment costs in hemophilia A patients with inhibitors, a study in Brazil reported. Conversely, treatment…

The U.S. Food and Drug Administration (FDA) has approved an update to the prescribing information for Altuviiio (efanesoctocog alfa), a long-lasting factor VIII (FVIII) replacement therapy for hemophilia A, to include the full results from a clinical trial, the XTEND-Kids study. As requested by Sanofi, which markets…

Switching from standard half-life factor replacement therapies to the extended half-life treatment Elocta (efmoroctocog alfa) improves bleed control among people with hemophilia A. That’s according to an analysis of data from the real-world A-SURE study (NCT02976753), which showed that switching to Elocta, sold as Eloctate in the…

A single dose of the gene therapy Roctavian (valoctocogene roxaparvovec-rvox) continues to prevent bleeds and the need for preventive treatment (prophylaxis) for up to five years in most treated men with severe hemophilia A, according to final Phase 3 trial results. Activity of factor VIII (FVIII), the clotting…

People whose hemophilia A is mild or moderate can show marked alterations to their joints on MRI scans, particularly in the ankles, despite having few joint bleeds, a study reported. These findings highlight the need for closer monitoring of joint health and a likely need for preventive treatment approaches in patients…

Weekly use of the experimental, long-acting therapy efanesoctocog alfa safely and effectively prevents bleeds in adolescents and adults with severe hemophilia A, according to top-line, one-year data from the Phase 3 XTEND-1 trial. The therapy — being jointly developed by Sanofi and Sobi — was also superior to approved preventive therapies…
