On February 16, Sarepta (SRPT) revealed that the FDA has accepted its efficacy supplement to the biologics license application (BLA) for Elevidys, a treatment of Duchenne muscular dystrophy (DMD). This ground-breaking development has catapulted the company’s stock by 7.8%, marking a momentous stride for both Sarepta and the DMD treatment landscape.
FDA Priority Review
The FDA has granted the Elevidys filing a Priority Review status, indicative of accelerated regulatory action, potentially reducing the review period by four months. Investors have their sights set on an eagerly anticipated final decision from the FDA, expected on Jun 21, 2024.
Historical Context
Last year, Elevidys was granted FDA approval under the accelerated pathway to treat ambulatory pediatric patients aged between four and five years with DMD. This landmark decision positioned Elevidys as the first approved gene therapy for DMD, setting a monumental precedent for the future of DMD management.
The Role of Efficacy Supplement
The efficacy supplement aims to broaden Elevidys’ labeled indication to encompass all DMD patients, regardless of age and ambulatory status. Furthermore, it endeavors to transition Elevidys’ accelerated approval to a traditional approval, indicating potential for broader therapeutic impact.
Market Response
Notably, Sarepta’s stock experienced a 7.8% surge on Feb 16, reflecting overwhelming positivity and investor confidence in the company’s future trajectory. Over the past year, SRPT shares have exhibited resilience, achieving an 8.1% gain despite a broader industry decline of 10.6%.

Impact of EMBARK Study
The BLA supplement is predominantly underpinned by data from the phase III EMBARK study, disclosed in October 2023. Despite falling short of its primary endpoint, the study achieved statistical significance on all pre-specified key secondary endpoints. This substantial evidence suggests that Elevidys has the potential to modify the course of DMD, ushering in a new era of DMD treatment and management.
Commercial Performance
Sarepta recently released encouraging unaudited results for the fourth quarter and full-year 2023, disclosing an anticipated $131.3 million in Elevidys sales for the fourth quarter. This brings the total sales figure to approximately $200.4 million for the full year, underscoring a remarkable commercial launch for a treatment introduced just the previous quarter.
Strategic Collaboration
SRPT developed Elevidys in collaboration with Roche (RHHBY), with the two entities joining forces via a licensing agreement in 2019 to jointly develop and commercialize Elevidys. The exclusive rights granted to Roche for the ex-U.S. markets stand as a testament to the global potential of Elevidys and illuminate Sarepta’s foray into the international treatment landscape.
Future Prospects
To meet regulatory prerequisites for Elevidys’ approval outside the United States, Sarepta is actively evaluating the safety and efficacy of Elevidys in the ongoing phase III ENVISION study in non-ambulatory and ambulatory DMD patients, highlighting the company’s commitment to global accessibility and impact.
