Sarepta Therapeutics Announces Expanded US FDA Approval of ELEVIDYS to Duchenne Muscular Dystrophy Patients Ages 4 and Above

– FDA grants traditional approval to ELEVIDYS for ambulatory Duchenne patients

– FDA grants accelerated approval to ELEVIDYS for non-ambulatory Duchenne patients

– Sarepta will host an investor conference call on June 21, 2024, at 8:30 a.m. ET

CAMBRIDGE, Mass.–(BUSINESS WIRE)–Jun. 20, 2024– Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today 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.

“Representing many years of dedicated research, development, investment and creative energy, the expansion of the ELEVIDYS label to treat Duchenne patients aged 4 and above, regardless of ambulatory status, is a defining moment for the Duchenne community. Today also stands as a watershed occasion for the promise of gene therapy and a win for science,” said Doug Ingram, president and chief executive officer, Sarepta. “At this pivotal moment, I want to give warm thanks to Drs. Jerry Mendell and Louise Rodino-Klapac for their dogged, 20-year pursuit of a gene therapy to treat this ruthless and life-robbing disease, to the FDA for following the scientific evidence to speed delivery of a therapy for a life-threatening rare disease to waiting patients, and to the many clinical investigators and courageous Duchenne families who have participated in the multiple studies that led to this important day.”

“Today’s expansion of the ELEVIDYS label represents the culmination of my 50-year pursuit of a treatment for Duchenne patients and, along with my colleague Dr. Louise Rodino-Klapac, a nearly 20-year effort to optimize and develop a gene therapy that could be safely and effectively delivered to muscle,” said Jerry Mendell, M.D., co-inventor of ELEVIDYS and senior advisor, Medical Affairs, Sarepta. “The initial approval of ELEVIDYS was a significant milestone, and the expanded indication means clinicians now have a treatment option for the great majority of boys and young men living with Duchenne. This expansion speaks to the success of the science, the evidence and the improvements in the trajectory of the disease we have seen to date across studies.”

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.

About ELEVIDYS (delandistrogene moxeparvovec-rokl)

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.
