Sanofi SA gained U.S. FDA approval for fitusiran as a first-in-class siRNA therapy for hemophilia. Branded Qfitlia, the antithrombin-lowering therapy is indicated for use as a prophylactic treatment to prevent or reduce bleeding episodes in people with hemophilia A or B, with or without inhibitors, and joins the small but growing group of non-factor therapy options, with the advantage of a broad label and a convenient dosing regimen.
Two trials presented at the annual meeting of the American Society of Hematology (ASH) showed that treatment with the antithrombin inhibitor fitusiran reduced the bleeding rate in patients with severe hemophilia by roughly 90%, regardless of whether they had type A or B, and whether they had developed antibodies to recombinant clotting factors.
