The U.S. Food and Drug Administration (FDA) is extending its review of BioMarin Pharmaceutical’s request to approve the gene therapy Roctavian (valoctocogene roxaparvovec) for adults with severe hemophilia A. A decision had been expected by the end of this month, but that date has now been…

Most children with hemophilia A given Altuviiio (efanesoctocog alfa) once a week were bleed-free throughout about a year of treatment.
