Sarepta Announces FDA Will Not Complete the Review of the Eteplirsen NDA By The PDUFA Date

The FDA has notified Sarepta that they are continuing their review of eteplirsen and will not be able to complete their work by the Prescription Drug User Fee Act (PDUFA) goal date of May 26, 2016. PPMD has been in touch with Sarepta and our coalition partners regarding next steps. We will update the community as we learn more.


PPMD continues to believe eteplirsen is safe and effective and suitable for accelerated approval, and we hope such a decision from FDA is forthcoming. 


The Duchenne community, in benefit-risk studies led by PPMD, has provided quantifiable data regarding our highest priority for emerging treatments -- stopping or slowing the progression of Duchenne. Those with experience on eteplirsen have communicated to the agency about the benefits they see and experience, and the scientific and clinical experts in this field have weighed in with their full support of this therapeutic option.  


We remain hopeful that the FDA is using this time to ensure that the collective voice of the community is being taken into account in this decision.

Sarepta Therapeutics Announces FDA Will Not Complete the Review of the Eteplirsen New Drug Application By The PDUFA Date

The FDA has communicated that they will continue to work past the PDUFA goal date and strive to complete their work in as timely a manner as possible.

About Sarepta Therapeutics

Sarepta Therapeutics is a biopharmaceutical company focused on the discovery and development of unique RNA-targeted therapeutics for the treatment of rare, infectious and other diseases. The Company is primarily focused on rapidly advancing the development of its potentially disease-modifying DMD drug candidates, including its lead DMD product candidate, eteplirsen, designed to skip exon 51. Sarepta is also developing therapeutics for the treatment of rare, infectious and other diseases. For more information, please visit us at

About Eteplirsen

Eteplirsen is designed to address the underlying cause of DMD by restoring the dystrophin messenger RNA (mRNA) reading frame, thus enabling the production of a shorter, functional form of the dystrophin protein. Eteplirsen uses Sarepta’s proprietary phosphorodiamidate morpholino oligomer (PMO) chemistry and exon-skipping technology to skip exon 51 of the dystrophin gene. Approximately 13 percent of the DMD population is amenable to exon 51 skipping. Data from clinical studies of eteplirsen in DMD patients have demonstrated a consistent safety and tolerability profile and have also shown measurable dystrophin protein expression. Promoting the synthesis of a shorter dystrophin protein is intended to slow the decline of ambulation and mobility seen in DMD patients. There currently is no approved treatment in the United States for DMD and eteplirsen has not been approved by the FDA or any regulatory authority for the treatment of DMD.

About Duchenne Muscular Dystrophy

DMD is an X-linked rare degenerative neuromuscular disorder causing severe progressive muscle loss and premature death. One of the most common fatal genetic disorders, DMD affects approximately one in every 3,500-5,000 males worldwide. A devastating and incurable muscle-wasting disease, DMD is associated with specific errors in the gene that codes for dystrophin, a protein that plays a key structural role in muscle fiber function. Progressive muscle weakness in the lower limbs spreads to the arms, neck and other areas. Eventually, increasing difficulty in breathing due to respiratory muscle dysfunction requires ventilation support, and cardiac dysfunction can lead to heart failure. The condition is universally fatal, and death usually occurs before the age of 30.
