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. The lack of access to residential addiction treatment facilities, can have very serious, even fatal outcomes for bleeding disorder (BD) patients in acute need of help with their addiction.
