The genetic blood disorder hemophilia B, caused by factor IX (FIX) deficiency, can be effectively controlled with gene replacement therapies, particularly when used for prevention. But because barriers to prophylaxis that include intravenous use, frequent dosing and medical costs are many, new research for better therapies is emerging. Researchers at the University of Wisconsin School of…

CSL Behring‘s new long-lasting recombinant factor VII single-chain therapy, Afstyla, for adults and children with hemophilia A, is now available nationwide. The drug, approved by the U.S. Food and Drug Administration (FDSA) in May, is the only single-chain product on the market specifically designed for reduction and control of…
Researchers from the PharmedOut project at Georgetown University Medical Center analyzed how pharmaceuticals market directly to people with hemophilia and found that, while strategies are effective, further regulation and studies are necessary. The study, “Direct-to-consumer Marketing to People with Hemophilia,” was published in the PLOS Medicine Policy Forum. PharmedOut involves doctors,…

Gene Therapy Approach, Tested on Liver Cells and Mice, Seen as Potential Treatment for Hemophilia B
Researchers, working with mice, have developed a new way of producing substantial numbers of gene-corrected liver cells with the possibility of repopulation in vivo. The strategy, which relies on the liver’s unusual regenerative skills, may hold promise for the treatment of diseases such as hemophilia B. The study by scientists at Oregon Health & Science University,…
Researchers at the University of Tokyo reviewed the status of physical activity among hemophilia patients to discuss strategies to encourage activity through a behavioral change approach by focusing on hemophilia-relevant factors such as benefits and bleeding risk, risk management of bleeding, physical activity characteristics, and difficulty in exercise adherence. The study,…
uniQure N.V., a leading pharmaceutical specialized in human gene therapy, has presented additional data from its clinical trial in hemophilia B patients at the 21st Congress of the European Hematology Association (EHA), June 9-12, in Copenhagen. The Phase 1/2 clinical trial of AMT-060 titled “Trial of…
A recent clinical trial indicates that replacement therapy with plasma-derived factor VIII is associated with lower incidence for development of inhibitors in patients with severe hemophilia A. The study,“A Randomized Trial of Factor VIII and Neutralizing Antibodies in Hemophilia A,” was published in The New England Journal of…
The difference in disease severity between Hemophilia A and B (HA, HB) was recently assessed in the study, “Clinical, Instrumental, Serological And Histological Findings Suggest That Hemophilia B May Be Less Severe Than Hemophilia A,” and published in Haematologica. HA and HB are caused by deficient clotting proteins,…
Facial and scalp swelling can be indicators of childhood hemophilia, but for children who are misdiagnosed and treated incorrectly, the effects of the disease’s elevated bleeding predisposition can be catastrophic. In the study, “Facial and Scalp Swelling in the Pediatric Population With Hemophilia: A Diagnosis Pitfall,” published in…
The safety and efficacy of emicizumab in patients with severe hemophilia A (HA) were recently evaluated in a study, “Factor VIII–Mimetic Function of Humanized Bispecific Antibody in Hemophilia A,” published in The New England Journal Of Medicine. Hemophilia A is caused by a lack of blood clotting factor…
