In rare instances, people with hemophilia can grow bones outside their skeletal tissue — with bone growth found in muscles and soft tissues — which significantly limit their range of motion, according to a recent case report. Surgery can improve the functional outcomes of patients with this abnormal bone…

Researchers reviewed the use of high-purity concentrates containing two plasma molecules that are lacking in patients with Von Willebrand disease (VWD), a hemorrhagic disorder. These products may be a good strategy for managing pediatric patients with VWD and hemophilia A (HA) who do not respond to other treatments. The study, “Human Von…

Treatment with marstacimab (PF-06741086), an experimental antibody-based therapy developed by Pfizer, reduced the number of bleeds in patients with severe hemophilia who took part in a Phase 1b/2 clinical study. This held true regardless of whether patients had hemophilia A or hemophilia B, or had inhibitors…

GenScript ProBio and Neoletix Biotechnology have entered into an agreement for clinical and commercial production of a lab-made version of coagulation factor VIII, a product that the companies hope will make the preventive treatment for hemophilia A more accessible to patients in China. Coagulation factor VIII, or FVIII,…

In the early days of a diagnosis, emotions run wild. Anxiety, helplessness, and anger are a few feelings that cloud the mind, and it’s difficult to even begin to understand what lies ahead. In 1996, my first son, Julian, was born and diagnosed with severe hemophilia A. In…

Gene therapy delivering the blood clotting factor VIII (FVIII) — whose lack causes hemophilia A — into the joints did better at protecting against hemophilic arthropathy (joint damage) than did administration into the bloodstream, a study in mice suggests. Its findings support the potential use of FVIII injected directly into…

The efficacy and safety profiles of preventive treatment with Hemlibra (emicizumab-KXWH) are not affected by age or the presence of some simultaneous health conditions, that is, comorbidities, in older people with hemophilia A. The findings are the result of a post hoc analysis of pooled data from Phase…

Treatment with the investigational gene therapy Roctavian (valoctocogene roxaparvovec) can reduce bleeding frequency and the use of replacement therapies, while maintaining or improving the quality of life of people with severe hemophilia A for up to five years, updated Phase 1/2 trial data show.  “These…

A participant in a Phase 3 clinical trial evaluating Roctavian (valoctocogene roxaparvovec), a gene therapy for hemophilia A, has been diagnosed with leukemia. A genetic assessment of the case, conducted by the therapy’s developer, BioMarin Pharmaceutical, suggested the cancer diagnosis was not linked to Roctavian. Details of…

AAV5 DetectCDx, a companion diagnostic test used to determine patient eligibility for the hemophilia A gene therapy Roctavian (valoctocogene roxaparvovec-rvox), has been cleared for use under more stringent European Union rules coming into effect in a few years. Specifically, the test gained the Conformité Européenne (CE) mark under…
