A lack of family history of disease can delay a diagnosis and timely initiation of preventive therapy in children with hemophilia A, increasing the need for intensive factor replacement therapy when a first bleeding event happens, a study shows. “These observations highlight the importance of an early diagnosis in…

CAR T-cell therapy, a type of treatment that weaponizes the body’s immune system and was originally developed to treat cancer, for the first time successfully treated a patient with acquired hemophilia A (AHA), a study reported. The study, “Anti-CD19 CAR-T cell therapy for acquired hemophilia A,”…
The blood-clotting protein factor VIII (FVIII) that’s missing or faulty in people with hemophilia A is flexible and adopts multiple shapes, some of which favor the binding of neutralizing antibodies that can reduce the effectiveness of FVIII replacement therapies, researchers have learned. “This helps explain why some people…
Acquired hemophilia A (AHA) arose in a 48-year old man with primary biliary cholangitis (PBC), an autoimmune liver disease, according to a case study. While AHA has been associated with autoimmune disorders, the researchers said a connection between AHA and PBC had not been reported previously. While “the…
A therapy designed to promote the growth of regulatory T-cells (Tregs) in the body prevented inhibitor development in a mouse model of hemophilia A that was treated with factor replacement therapy, a study showed. Inhibitors, a type of neutralizing antibody some patients develop that can make replacement therapies…
Jivi (damoctocog alfa pegol) has received approval from the U.S. Food and Drug Administration (FDA) that now extends to children with hemophilia A as young as 7 years old. Jivi had previously been authorized for hemophilia A patients 12 and older. The therapy, which is sold by Bayer,…
Prophylactic (preventive) treatment for hemophilia A and B is generally more effective than on-demand treatment in reducing the frequency of bleeding, but the benefit is not as clear in patients who have developed inhibitors that limit how well replacement clotting factors work. That’s according to real-world data from…
A single-center U.S. study found relatively little genetic testing was done for girls with a 50% risk of being a hemophilia carrier — people with the altered gene who don’t have hemophilia themselves but can pass it to their children — over a four-year period in Washington state.
Children with severe hemophilia A with blood group O are not at increased risk of developing neutralizing antibodies against factor VIII (FVIII) replacement therapy, a study found. The study, “Blood Group O Does Not Increase the Risk of Inhibitors in Severe Haemophilia A: Data from the…
Beqvez (fidanacogene elaparvovec-dzkt), a one-time gene therapy developed by Pfizer that was formerly approved for hemophilia B, was found to be safe and effective in reducing bleeding episodes and the need for factor replacement therapy in a small group of men. That’s according to results from a long-term…
