FDA Oks Sanofi’s Hemophilia A Drug
FDA has approved a Bioverativ Therapeutics (a Sanofi company) BLA for Altuviiio (efanesoctocog alfa), a recombinant DNA-derived, factor VIII concentrate indicated for use in adults and children with hemophilia A. The drug is approved for routine prophylaxis to reduce bleeding episodes, on-demand treatment and control of bleeding episodes, and perioperative management of bleeding, according to the approved label.
Sanofi recently announced positive topline results from the pivotal phase 3 XTEND-1 study in previously treated patients (N=159) at least 12 years old with hemophilia A. The study met the primary end point, showing clinically meaningful prevention of bleeding episodes in people with severe hemophilia A, who received weekly prophylaxis with efanesoctocog over 52 weeks.
The study results show the drug provides “near normal factor activity levels for an extended period of time (the majority of a week) with a single dose, which is a first for hemophilia A,” the company says. “The data show that efanesoctocog alfa can offer patients increased bleed protection, leading to improved outcomes, such as reduced pain and improved physical functioning, that may impact daily life with a reduced treatment burden.”
Additionally, Sanofi says Altuviiio is the first investigational factor VIII therapy that has been shown to “break through the von Willebrand factor ceiling, which imposes a half-life limitation on current factor VIII therapies.”
