Approximately 30,000 males have hemophilia in the U.S., according to estimates from a recent study, which also found that patients with hemophilia are generally young and that the disease is more common in Northeastern and Midwestern states. The study, “Occurrence rates of haemophilia among males in…

Three hemophilia B patients said they were able to lead a relatively normal life, including being more active and participating in sports, about three years after receiving the investigational gene therapy AMT-060 in a clinical trial. Their experiences were reported in the study, “The Patient…

Data from a completed Phase 2b trial indicate that dalcinonacog alfa (DalcA) is an effective and safe therapy to prevent bleeding in people with severe hemophilia B. Final results from this open-label study in six patients are expected by June. “We are pleased to have successfully completed the DalcA Phase…

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 therapy specifically…

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…
