Despite Eye-Popping $3.5 Million Price Tag For Gene Therapy Hemgenix, Budget Impact For Most Payers Will Be Relatively Small

On November 22nd, the Food and Drug Administration (FDA) approved the world’s first gene therapy for hemophilia B; Hemgenix (etranacogene dezaparvovec). Hemgenix will have a list price of $3.5 million per use.
