An experimental therapy may help remove harmful antibodies that reduce the effectiveness of factor replacement therapies in hemophilia A, potentially offering a new way to overcome one of the most significant complications of standard care. The therapy uses chimeric autoantibody receptor T cells, or CAAR-T cells. These are…

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…

The ongoing Phase 1/2 Alta trial continues to show that a single infusion of SB-525, an investigational gene therapy, leads to stable and clinically relevant improvements in clotting factor VIII and marked reductions in the need for replacement therapy in patients with hemophilia A. This preliminary follow-up data…

A single dose of the experimental gene therapy AMT-180 promotes clinically meaningful blood-clotting activity, independent of factor VIII levels, in mouse and primate models of hemophilia A, a study shows. These preclinical findings were discussed in a presentation, “Towards AAV5-Mediated Gene Therapy for Hemophilia A with a Factor IX…

Casebia’s two-stage gene therapy approach was successful in delivering the human gene coding for clotting factor VIII (FVIII) in a mouse model of hemophilia A, leading to stable and increasing levels of the factor, researchers said. “Our scientific team, led by Alan Brooks, Ph.D., have achieved a notable…

The U.S. Food and Drug Administration (FDA) has approved the one-time gene therapy Roctavian (valoctocogene roxaparvovec-rvox) for eligible adults with severe hemophilia A.  Roctavian now becomes the first gene therapy to win FDA approval for the treatment of hemophilia A in the U.S. “Today’s approval of Roctavian builds…

Roche is initiating a Phase 3 clinical trial to test the experimental gene therapy SPK-8011 in people with hemophilia A. The company announced the move in its 2023 half-year results. At the same time, however, Roche is discontinuing the development of another investigational hemophilia A gene therapy…

Health Canada has approved Altuviiio (efanesoctocog alfa) to treat children, adolescents, and adults with hemophilia A, with the aim of preventing and controlling bleeds, including those occurring around the time of surgery. “This approval represents important progress in the treatment of patients with hemophilia A in Canada,” Stephanie…

A combination of Cyklokapron and Feiba — usually avoided due to a perceived risk of blood clots — appears to be safe and effective for treating patients with acquired hemophilia A (AHA), though these early study results need to be confirmed in clinical trials, researchers in Italy say. The study, “…
