Priority Review for Sanofi’s Efanesoctocog Alfa
FDA has accepted for priority review a Sanofi BLA for efanesoctocog alfa to treat hemophilia A. The agency set a PDUFA action date of 2/28/23 for its decision on the BLA, the company says.
Sanofi says the BLA was supported by data from the pivotal XTEND-1 Phase 3 study that it says demonstrated a clinically meaningful prevention of bleeds and superiority to prior factor prophylaxis based on an intra-patient comparison.
Efanesoctocog alfa is described as a novel and investigational recombinant factor VIII therapy that is designed to extend protection from bleeds with once-weekly prophylactic dosing for people with hemophilia A.
