FDA decides in early 2027 whether two Sarepta exon-skipping drugs keep their approvals

Sarepta Therapeutics sells four approved drugs for Duchenne muscular dystrophy, a genetic muscle-wasting disease; two hold accelerated approvals that FDA is reviewing for conversion to full approval.

Sarepta sold $328.7 million of Duchenne drugs in the second quarter: $230.6 million of exon-skipping PMOs and $98.1 million of ELEVIDYS, and guides to $1.2 to $1.3 billion for 2026. FDA expects to decide in early 2027 whether AMONDYS 45 and VYONDYS 53 convert to full approval, although the ESSENCE confirmatory trial missed its primary endpoint. ELEVIDYS lost its non-ambulatory indication in November 2025. Sarepta now needs its siRNA programs, with DM1 and FSHD data due in the second half of 2026.
