People with severe hemophilia A who have two or more self-described problem joints — a person-centric characterization of joints based on underlying joint damage, pain, and mobility impairment, regardless of bleeding — have worse clinical outcomes, including more chronic pain, a new study from researchers in Europe has found.

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,…

An infant was diagnosed with severe hemophilia A after developing splenic injury (injury to the spleen), a rare condition among newborns. For the first time, however, a newborn with these conditions was successfully treated with recombinant factor VIII replacement therapy without the need for surgical intervention, doctors reported. The report, titled…

Biogen and Sobi  announced that they will be presenting updated and long-term data on two approved hemophilia treatments, Eloctate  (marketed as Elocta in Europe) for hemophilia A, and Alprolix for hemophilia B, at the World Federation of Hemophilia (WFH)’s 2016 World Congress next week. Specifically, data from separate Phase 3 extension studies evaluating each treatment’s safety and…

The U.S. Food and Drug Administration (FDA) has granted priority review for the approval of efanesoctocog alfa, with a decision on the potentially longer-lasting hemophilia A treatment due early next year. The regulatory agency accepted an application from developers Sobi and Sanofi requesting approval of the…

A hemophilia patient has died in a Phase 3 trial evaluating Roche’s  experimental treatment emicizumab (ACE910), raising further concern about its safety. Preliminary indications are that the patient died of a rectal hemorrhage and not emicizumab therapy, however, the company said. The death follows reports of serious blood-clotting events in four…

European authorities have recommended conditional marketing authorization for Roctavian (valoctocogene roxaparvovec), BioMarin Pharmaceutical’s one-time gene therapy for adults with severe hemophilia A. This positive decision, from the Committee for Medicinal Products for Human Use (CHMP), makes Roctavian the first gene therapy for hemophilia A to be recommended for European…

A new combination of gene and cell-based therapy durably delivered therapeutic levels of factor VIII (FVIII) — the blood clotting protein missing or defective in people with hemophilia A — and eased bleeding in a mouse model of the disease, a study from the HemAcure Consortium shows.

ASC Therapeutics is partnering with Vigene Biosciences to support the manufacturing process of its current and future gene therapy clinical platforms — including its ongoing hemophilia A program. “We are proud to welcome Vigene, a global leader in gene therapy process development and GMP [Good Manufacturing…

First results from the Phase 3 HAVEN 2 study evaluating the effectiveness and safety of emicizumab in children younger than 12 with hemophilia A look promising. Roche announced that preventive treatment with emicizumab caused a reduction of the number of bleeds over time, with no major adverse events reported so…
