Sarepta Therapeutics Rallies as FDA Reviews Traditional Approval Path
Sarepta Therapeutics shares climbed 5.4% to $17.93 in Tuesday trading, shaking off a 17% year-to-date decline after the FDA accepted supplemental applications for two Duchenne muscular dystrophy treatments. The agency set a target action date of February 28, 2027, for the drugmaker’s bid to secure traditional, non-accelerated approval.

Experts point to the ultra-rare nature of the patient populations affected by exon 45 and exon 53 mutations, combined with real-world clinical evidence, as key factors supporting the treatments' longevity. Duchenne muscular dystrophy causes progressive muscle degeneration and weakness, leaving few alternatives for those afflicted by the genetic disorder.
