Re-administering a viral vector-based gene therapy for hemophilia A was shown to be safe and to achieve long-term improvement in a dog model of the disease — even after neutralizing antibodies were evident following the initial treatment. The study, “An observational study from long-term AAV re-administration in…

Total joint replacement (TJR) is more common in severe hemophilia patients requiring more frequent treatment, according to a population-based study in Taiwan. The findings also revealed that the incidence of TJR does not differ between hemophilia A and B. The study, “Comparison of Total Joint…

Single or combination therapy with bypassing agents used for hemophilia A patients with inhibitors can be suitable treatment options for children with hemophilia B with factor IX inhibitors as well, a case series suggests. The report, “Alternative treatment options…

The U.S. Food and Drug administration (FDA) has approved Genentech’s Hemlibra (emicizumab-kxwh) for routine prophylactic (preventive) treatment of patients with hemophilia A without factor VIII inhibitors. Hemlibra is now the sole available prophylactic treatment for patients with hemophilia A with and without factor VIII inhibitors that can…

The investigational gene therapy SB-525 is tolerated well by patients, and dose-dependent responses are positive, according to preliminary results of a Phase 1/2 clinical trial of hemophilia A. The potential gene therapy is being developed as a partnership between Sangamo Therapeutics and Pfizer. It consists of…

Hemlibra (emicizumab) was able to prevent excessive bleeding in patients with severe hemophilia A without inhibitors, according to results from a Phase 3 trial. Trial findings were published in the study, “Emicizumab Prophylaxis in Patients Who Have Hemophilia A without Inhibitors,” in The New England Journal of…

The U.S. Food and Drug Administration has approved Bayer’s Jivi, previously known as BAY94-9027, as a preventive therapy for hemophilia A in patients ages 12 and older, the company announced. The recommended regimen is for Jivi to be administered intravenously (into the blood) two times a week (30-40 IU/kg),…

Health Canada has approved Hemlibra (emicizumab) as a treatment to prevent or reduce bleeding in Hemophilia A patients in Canada who have factor VIII inhibitors. Hemlibra is an antibody therapy designed to combine factors IX and X of the blood clotting series and promote clotting. Restoring the…

A gene therapy that can treat patients with severe hemophilia A is likely to be more cost-effective over the long term than reliance on prophylactic (preventive) therapy using factor VII (FVIII), a model-based analysis of the two treatment approaches reports. The study, “Gene therapy in hemophilia A: a cost-effectiveness…

Precision BioLogic revealed promising data on a new kit for the measurement of FVIII inhibitors (factor VIII) in patients with hemophilia A. The results were presented at the International Society on Thrombosis and Haemostasis’ Scientific and Standardization Committee (SSC) meeting July 18-21 in Dublin, Ireland. Researchers presented their…
