The U.S. Food and Drug Administration (FDA) has accepted — under priority review — a marketing application for Valrox (valoctocogene roxaparvovec), BioMarin Pharmaceutical’s investigational gene therapy for hemophilia A. This is the first time the FDA has accepted an application for a gene…

When administered at a high dose, a gene therapy for hemophilia B known as FLT180a seems able to restore the activity of clotting factor IX (FIX) within a normal range in men with moderate-to-severe disease, early data from Phase 1/2 trial show. The findings were announced in an oral presentation,…

Esperoct (turoctocog alfa pegol) is now available in the U.S. to treat and control bleeding in adults and children with hemophilia A, the therapy’s manufacturer, Novo Nordisk, announced. The treatment’s use was approved by the U.S. Food and Drug Administration (FDA) in February 2019, but its availability…

A modified version of the coagulation protein factor X was able to significantly reduce bleeding in a mouse model of hemophilia A, and may offer a way of treating people with this disease due to factor VIII deficiency, a study suggests. Lab work also showed a potential for treating people…

Ease of use, fear of the unknown, and healthcare providers’ advice are all major factors that play a role in whether people with hemophilia want to switch to new treatment options, a small study suggests. The study, “Patient Perspectives on Novel Treatments in Haemophilia: A Qualitative Study,”…

A single injection of uniQure‘s gene therapy AMT-061 (etranacogene dezaparvovec) is well-tolerated, effectively increases the levels of clotting factor IX (FIX), and completely prevents bleedings without the need for additional FIX injections in people with hemophilia B, even in the presence of neutralizing antibodies against the treatment,…

The Fitbit wristband can help with the continuous monitoring of physical activity in people with hemophilia, but other strategies are needed to encourage increased activity, a study suggests. The study, “Physical Activity Monitoring and Acceptance of a Commercial Activity Tracker in Adult Patients with Haemophilia…

The gene therapies AMT-060 and AMT-061 both restored coagulation factor IX levels in a primate model of hemophilia B, but AMT-061 resulted in greater coagulation activity at the same dose, a new study reports. The study, “Enhanced Factor IX Activity Following Administration of AAV5-R338L “Padua” Factor IX…

Problematic thrombotic events are fairly rare in people using NovoSeven, among all types of bleeding disorders for which it is approved, including hemophilia, a review study shows. The study, “Thrombotic events with recombinant activated factor VII (rFVIIa) in approved indications are rare and associated with older age,…

New data from clinical studies suggests that long-term preventive treatment of severe hemophilia A with Eloctate, or severe hemophilia B with Alprolix, increased quality of life and reduced annual bleeding rates. The data was presented in Melbourne, Australia at ISTH 2019, the 27th Congress of the International Society…
