Sarepta Therapeutics, Inc. announced U.S. Food and Drug Administration (FDA) approval of an expansion to the labeled indication for ELEVIDYS (delandistrogene moxeparvovec-rokl) to include individuals with Duchenne muscular dystrophy (DMD) with a confirmed mutation in the DMD gene who are at least 4 years of age. Confirming the functional benefits, the FDA granted traditional approval for ambulatory patients. The FDA granted accelerated approval for non-ambulatory patients.

Continued approval for non-ambulatory Duchenne patients may be contingent upon verification of clinical benefit in a confirmatory trial. ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene. Consistent with the accelerated approval pathway, Sarepta has committed to conduct and submit the results of a randomized, controlled trial to verify and confirm the clinical benefit of ELEVIDYS in patients with Duchenne muscular dystrophy who are non-ambulatory.

ENVISION (Study SRP-9001-303), a global, randomized, double-blind, placebo-controlled Phase 3 study of ELEVIDYS in non-ambulatory and older ambulatory individuals with Duchenne, is underway and intended to serve as this postmarketing requirement. As part of a collaboration agreement signed in 2019, Sarepta is working with Roche to transform the future for the Duchenne community, enabling those living with the disease to maintain and protect their muscle function. Sarepta is responsible for regulatory approval and commercialization of ELEVIDYS in the U.S., as well as manufacturing.

Roche is responsible for regulatory approvals and bringing ELEVIDYS to patients across the rest of the world. ELEVIDYS (delandistrogene moxeparvovec-rokl) is a single-dose, adeno-associated virus (AAV)-based gene transfer therapy for intravenous infusion designed to address the underlying genetic cause of Duchenne muscular dystrophy ? mutations or changes in the DMD gene that result in the lack of dystrophin protein ?

through the delivery of a transgene that codes for the targeted production of ELEVIDYS micro-dystrophin in skeletal muscle. ELEVIDYS is indicated for the treatment of Duchenne muscular dystrophy (DMD) in individuals at least 4 years of age. For patients who are ambulatory and have a confirmed mutation in the DMD gene.

For patients who are non-ambulatory and have a confirmed mutation in the DMD gene. The DMD indication in non-ambulatory patients is approved under accelerated approval based on expression of ELEVIDYS micro-dystrophin (noted hereafter as ?micro-dystrophin?) in skeletal muscle. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
