Endothelial cells — those that line the inside of blood vessels — derived from stem cells of people with hemophilia A and modified to produce functional factor VIII were able to ease blood loss in a mouse model of the disease, a study reported. These findings support the potential of induced…

Some $80.3 million in financing will support the first clinical trial of Sigilon Therapeutics’ new hemophilia A cell therapy candidate, SIG-001, the company said. The trial is expected to begin by June. Last August, the U.S. Food and Drug Administration (FDA) granted the potential cell therapy…

Cells derived from hemophilia A patients — genetically reprogrammed to produce a functional clotting factor VIII (FVIII) that’s missing or not working in people with the blood disease — were successfully grafted into hemophiliac mice, restoring blood levels of FVIII and significantly improving…

Preventive treatment with Kovaltry (octocog alfa) is safe and effective at preventing bleeds, including joint bleeds, for up to two years in people with hemophilia A, a long-term extension study shows. Findings were reported in the study “BAY 81-8973 demonstrated efficacy, safety and joint status improvement…

The U.S. Food and Drug Administration (FDA) has accepted — under priority review — a marketing application for Valrox (valoctocogene roxaparvovec), BioMarin Pharmaceutical’s investigational gene therapy for hemophilia A. This is the first time the FDA has accepted an application for a gene therapy specifically…

Light Chain Bioscience, a unit of Swiss biotech Novimmune, has completed the discovery phase of its collaborative program with Takeda for developing bispecific antibodies — protective proteins produced by the immune system — that mimic the activity of blood clotting factor VIII as a treatment for…

Esperoct (turoctocog alfa pegol) is now available in the U.S. to treat and control bleeding in adults and children with hemophilia A, the therapy’s manufacturer, Novo Nordisk, announced. The treatment’s use was approved by the U.S. Food and Drug Administration (FDA) in February 2019, but its availability…

Researchers have developed a faster, less expensive, reliable method for non-invasive prenatal diagnosis (NIPD) of hemophilia A. Future, larger studies are required to confirm the utility of the method, which could be used for the NIPD of hemophilia A and type B, as well as other X-linked…

Prophylactic, or preventive, use of Hemlibra (emicizumab) promotes joint health in people with hemophilia A, according to a new analysis of data from a Phase 3 trial. These findings were announced in the oral presentation “Bone and Joint Health Markers in Persons with Hemophilia A (PwHA)…

BioMarin is considering pricing its hemophilia A gene therapy Valrox (valoctocogene roxaparvovec), should it be approved, at $2 million to $3 million. That range would make Valrox the world’s most expensive one-time therapy. But, the company argues, this first gene therapy for any form of inherited hemophilia could…
