On November 22, the U.S. Food and Drug Administration approved Hemgenix (etranacogene dezaparvovec), an adeno-associated virus (AAV) vector-based gene therapy. It is approved for the treatment of adults with hemophilia B who currently use factor IX (FIX) prophylaxis therapy, or have current or historical life-threatening hemorrhage, or have repeated, serious spontaneous bleeding episodes.

Historically, many residential substance use disorder (SUD) facilities have denied admittance to individuals with bleeding disorders – the basis of these denials are most often the use of self-administered, intravenous medications such a as factor replacement therapies.
