Introduction

Nonacog Alfa is a recombinant form of human Factor IX, a protein used to treat clotting disorders including hemophilia B and von Willebrand disease. It is approved by the U.S. Food and Drug Administration (FDA) for the prophylactic and on-demand treatment of hemophilia B. This recombinant factor IX is produced through biotechnology.
