Despite the increasing use of preventive factor VIII (FVIII) replacement therapy, people living with hemophilia A in Japan still experience a significant disease burden, according to a recent study. Using information from health records databases, researchers found that while patients have used increasing doses and spent more on medical…

Clinical symptoms of acquired hemophilia A in elderly patients can vary widely, a series of six case reports reveals. Also, these patients should be managed individually in order to achieve the best care and outcome, researchers suggest. The cases were described in the study “Management of…

In real-world settings, Hemlibra (emicizumab-KXWH) can safely control bleeds in children with hemophilia A better than previous treatment regimens, a study reports. Hemlibra’s improved efficacy was more pronounced among patients with inhibitors, or neutralizing antibodies targeting factor VIII (FVIII), which is the clotting protein missing in people with…

Precision BioLogic has developed what it says is a better way of detecting levels of substances in hemophilia A patients’ blood that prevent clotting factor therapies from working as well as they should. It collaborated with Roche and Genentech in creating a kit it says can detect levels of the…

Researchers at Emory University School of Medicine have developed a small-scale model system to study bleeding and clotting of wounds. The miniature model also accurately reproduces the alterations observed in hemophilia A patients. Their work, “A microengineered vascularized bleeding model that integrates the principal components of hemostasis”, was published in…

Changes in the cellular microenvironment could influence immune responses against factor VIII (FVIII) replacement therapy in people with hemophilia A, a new study suggests. Data from the cell culture study showed that FVIII proteins that cause an immune reaction differ depending on which other molecules are present in…

In the final days of 2023, an adult with hemophilia A named Maxwell became the first person in the U.S. to receive treatment with the one-time gene therapy Roctavian (valoctocogene roxaparvovec-rvox) — approved in June of last year — outside of clinical trials. “Receiving this treatment is liberating…

Weekly use of the experimental therapy efanesoctocog alfa maintains therapeutic levels of factor VIII (FVIII) — the missing clotting factor in hemophilia A — and significantly improves physical and joint health, while reducing pain, in adolescents and adults with a severe form of the disease. These are the…

A single dose of the investigational gene therapy BAY 2599023 safely promotes a sustained production of factor VIII (FVIII),  effectively preventing spontaneous bleeds in people with severe hemophilia A, a Phase 1/2 trial shows. Two of the six patients treated to date in this clinical study, both given the…

The protein missing or defective in people with hemophilia A, called blood coagulation factor VIII (FVIII), is able on its own to stimulate immune responses in a mouse model, a study suggests. This immune response to FVIII is dependent on a set of distinct immune cells within the spleen,…
