Adults and adolescents with hemophilia A or hemophilia B without inhibitors experienced significantly fewer bleeding episodes when using concizumab as a prophylactic (preventive) treatment compared with those who weren’t on any prophylaxis. That’s according to data from explorer8 (NCT04082429), an ongoing Phase 3 clinical study in which…

Hemophilia patients who received intensive factor VIII (FVIII) replacement therapy for better joint health were nearly five times more likely to see a reduction or complete resolution of synovial hypertrophy — swelling and thickening of the connective tissue that lines the inside of a joint — compared with those…

Pfizer’s Hympavzi (marstacimab) has been approved in the European Union (EU) to prevent or reduce the frequency of bleeding episodes in adults and children, ages 12 and older, with severe hemophilia A or hemophilia B who weigh at least 35 kg (77 pounds) and haven’t developed neutralizing…

Metagenomi, which is developing MGX-001, a gene-editing therapy for hemophilia A, is preparing to initiate investigational new drug (IND)-enabling activities that seek to support the therapy’s transition from preclinical to clinical testing.

Clotting proteins that are missing or are defective in hemophilia can directly affect the activity of cells responsible for maintaining bone health, a study found. The findings shed new light on why bone problems are a common issue among people with hemophilia, researchers said. The study, “…

Prophylactic replacement therapy to prevent bleeds was more cost-effective than on-demand treatment of active bleeds for children and adolescents in China with moderate or severe hemophilia A without inhibitors, a study reported. The superior cost-effectiveness of prophylaxis over on-demand treatment was mainly driven by the on-demand costs of treating…

Real-world use of the extended half-life factor replacement therapy Elocta (efmoroctocog alfa) was associated with better bleed control than standard half-life products among people with hemophilia A, according to findings from an observational study in Europe. Elocta, sold as Eloctate in the U.S., was also associated with fewer…

People with hemophilia are more likely to be infected with the SEN virus (SENV), which is associated with blood transfusion hepatitis, or liver inflammation, than healthy people, a study in Iran suggests. The virus was detected in more than half of patients with hemophilia A and most commonly in…
