1 INDICATIONS AND USAGE ELEVIDYS is indicated for the treatment of patients 4 years of age and older with Duchenne muscular dystrophy (DMD), who are ambulatory and have a confirmed mutation in the DMD gene [see Clinical Pharmacology ( 12.2 ), Clinical Studies ( 14 )] . ELEVIDYS is an adeno-associated virus vector-based gene therapy indicated for the treatment of patients 4 years of age and older with Duchenne muscular dystrophy (DMD) who are ambulatory and have a confirmed mutation in the DMD gene. ( 1 , 12.2 , 14 ) Limitations of Use: ELEVIDYS is not recommended in patients with: Preexisting liver impairment (defined as gamma-glutamyl transferase [GGT] > 2 x upper limit of normal or total bilirubin > the upper limit of normal not due to Gilbert's syndrome) or active hepatic viral infection due to the high risk of acute serious liver injury and acute liver failure. Recent vaccination (within 4 weeks of treatment) due to immunogenicity and potential safety concerns. Active or recent (within 4 weeks) infections due to safety concerns.

1 INDICATIONS AND USAGE VYONDYS 53 is indicated for the treatment of Duchenne muscular dystrophy (DMD) in patients who have a confirmed mutation of the DMD gene that is amenable to exon 53 skipping. This indication is approved under accelerated approval based on an increase in dystrophin production in skeletal muscle observed in patients treated with VYONDYS 53 [see Clinical Studies ( 14 )] . Continued approval for this indication may be contingent upon verification of a clinical benefit in confirmatory trials.
