Sarepta’s SRP-9003 Gene Therapy Shows Clinical Promise but Faces FDA Uncertainty
SHERIDAN, WYOMING – October 15, 2025 – Sarepta Therapeutics is pressing forward with its limb-girdle muscular dystrophy (LGMD) gene therapy, SRP-9003, despite a strategic pivot earlier this year toward small interfering RNA (siRNA) therapies and ongoing regulatory challenges. New late-stage data presented at the World Muscle Society Congress in Vienna suggest the therapy could still hold clinical and commercial potential—if Sarepta can navigate FDA scrutiny and rebuild trust in its gene therapy platform.
Promising Clinical Outcomes at WMS 2025
At the 30th annual World Muscle Society (WMS) meeting, Sarepta shared Phase III data from its EMERGENE trial evaluating SRP-9003 in 17 LGMD patients. The therapy, designed to restore beta-sarcoglycan expression—a key muscle-stabilizing protein—met its primary endpoint after 60 days of observation.
