Sarepta Therapeutics Completes NDA Submission to FDA for Eteplirsen for the Treatment of Duchenne Muscular Dystrophy Amenable to Exon 51 Skipping

Sarepta Therapeutics, Inc.

, a developer of innovative RNA-targeted therapeutics, today announced the completion of the rolling submission of a New Drug Application (NDA) to the United States Food and Drug Administration (FDA) for eteplirsen on June 26, 2015. Eteplirsen, the Company's lead drug candidate, targets the underlying cause of Duchenne muscular dystrophy and is designed to enable the production of a functional internally truncated dystrophin protein in patients with mutations amenable to exon 51 skipping. Approximately 13% of people with Duchenne muscular dystrophy are estimated to have a mutation targeted by Eteplirsen/exon 51 skipping. "The completion of our NDA submission for eteplirsen represents the culmination of the efforts of our employees, investigators, clinical trial sites, and most importantly the patients and families of the Duchenne community," said Edward M. Kaye, interim chief executive officer and chief medical officer. "We look forward to working with the FDA during the regulatory process in pursuit of our goal of bringing eteplirsen to patients amenable to exon 51 skipping, while maintaining our organizational focus on advancing our PMO technology to target other DMD subpopulations amenable to exon-skipping as quickly as possible." The NDA submission includes a request for Priority Review. Previously, eteplirsen has been granted Orphan and Fast Track status by the FDA. The rolling submission of the NDA began on May 20, 2015, after the completion of a pre-NDA meeting with the FDA held on May 19, 2015.
