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…
Sobi and Sanofi’s philanthropic organization, Foundation S, have announced an additional donation of up to 100 million international units (IUs) of clotting factor treatment to support the World Federation of Hemophilia (WFH) Humanitarian Aid Program. This is the second renewal of the 10-year partnership that will continue…
Children with hemophilia have problems with dynamic balance — the ability to maintain balance while moving — and an increased risk of falls compared with healthy peers, according to a new study by two researchers in Turkey. The findings showed, however, that such impairments were not related to joint…
A greater range of motion before surgery is associated with better post-surgical outcomes for people with hemophilia who undergo knee replacement surgery. That’s according to a recent study that also found that having the surgery on both knees at the same time had a negative impact on the overall…
A delayed diagnosis is common for people with acquired hemophilia A (AHA), according to a new study that found that it took more than a month to get a diagnosis after the first bleeding episode for about 1 in 3 patients. Despite these delays, all AHA patients in the…
Prophylactic replacement therapy to prevent bleeds was more cost-effective than on-demand treatment of active bleeds for children and adolescents in China with moderate or severe hemophilia A without inhibitors, a study reported. The superior cost-effectiveness of prophylaxis over on-demand treatment was mainly driven by the on-demand costs of treating…
Note: This story was updated July 30, 2024, to clarify patients participating in AFFINE had moderately severe to severe disease, and that a secondary study goal involved the mean treated annualized bleeding rate. Giroctocogene fitelparvovec, an investigational gene therapy for adults with hemophilia A, is generally well…
TU7710, an experimental treatment for managing bleeds in people with hemophilia who have inhibitors, demonstrated an average half-life that ranged from 10.4 to 16.6 hours across different doses in a Phase 1a study with healthy volunteers. This extended half-life, that is, the time it takes for a medication’s levels…
Efanesoctocog alfa, a long-lasting factor VIII (FVIII) replacement therapy, has now been approved in the European Union for hemophilia A. It will be marketed under the brand name Altuvoct. Altuvoct can be used as an on-demand treatment for bleeding episodes, a once-weekly prophylactic (preventive) therapy to reduce the…
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…
