Sarepta Therapeutics (Formerly known as AVI BioPharma, Inc.) (SRPT)'s Ebola, Marburg Virus Drugs Get FDA Fast Track Status

CAMBRIDGE, MA--(Marketwire - September 18, 2012) - Sarepta Therapeutics, Inc. (NASDAQ: SRPT), a developer of innovative RNA-based therapeutics, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track status for the development of its lead infectious disease drug candidates, AVI-7288 and AVI-7537, for the treatment of Marburg virus and Ebola virus, respectively. Sarepta has been developing these platform-based therapeutics under a U.S. Department of Defense (DoD) contract managed by the Joint Project Manager Transformational Medical Technologies (JPM-TMT) Project Management Office, a component of the Joint Program Executive Office for Chemical and Biological Defense (JPEO-CBD).

The FDA's Fast Track program is designed to facilitate the development of, and expedite the review of, new drugs that have shown the potential to address an unmet medical need in a serious or life-threatening disease. Fast Track designated drugs qualify for Priority Review, an expedited review process available to drugs that offer major advances in treatment or provide a treatment where no adequate therapy exists.

"This is a significant milestone for Sarepta," said Chris Garabedian, President and CEO. "The FDA recognizes the significant unmet medical need for these highly lethal hemorrhagic fever viruses and the necessity to move the development of these drugs forward as fast as possible to ensure effective medical countermeasures for the Warfighter. We believe Sarepta has the only drug candidates for Marburg and Ebola with Fast Track designation and expect this designation will provide an expedited approval process to help DoD achieve its mission of protecting the nation from biothreats."

Sarepta continues to evaluate the safety and efficacy of AVI-7288 for the treatment of Marburg virus following FDA's Animal Rule and next plans to initiate a Phase I multiple ascending dose study to characterize the safety, tolerability and pharmacokinetics of AVI-7288 after repeat dosing in healthy adult volunteers. Currently, the JPM-TMT's Ebola programs, including development of AVI-7537, remain under a temporary stop-work order due to funding constraints.

About Marburg Virus

Marburg hemorrhagic fever is a severe and potentially fatal disease in humans first recognized in 1967. It is caused by an RNA virus of the Filoviridae family and is understood to be endemic to Africa. The Marburg virus is classified as a Category A bioterrorism agent by the Centers for Disease Control and Prevention, or CDC, and was determined to pose a material threat to national security and public health by the Secretary of Homeland Security in 2006. Onset of the disease is often sudden, and the symptoms include fever, chills, nausea, vomiting, chest pain and diarrhea. Increasingly severe symptoms may also include massive hemorrhaging and multiple organ dysfunctions. There are currently no treatments for Marburg virus infection beyond supportive care.

About Ebola Virus

The hemorrhagic fever caused by the Ebola virus is severe and often fatal in humans. The disease was first recognized in 1976 and is one of two members of a family of RNA viruses called Filoviridae. The disease is generally understood to be endemic to parts of Africa. Onset of illness from Ebola virus is abrupt with symptoms that include fever, headache, muscle ache, vomiting and stomach pain. Internal and external bleeding may also be observed in some patients. There are currently no treatments for Ebola virus infection beyond supportive care and the mortality rate is very high.

About Sarepta's PMOplus® Chemistry

PMOplus® chemistry is an advanced generation of Sarepta's phosphorodiamidate morpholino oligomer, or PMO, technology pioneered by Sarepta. The PMO platform is designed to provide a stable chemistry backbone with superior drug-like characteristics for Sarepta's advanced RNA-based therapeutics. PMOplus® chemistry includes specific molecular charges positionally inserted into the PMO's inherent charge-neutral backbone. PMOplus® has potentially broad therapeutic applications and has thus far shown to be particularly effective in increasing the potency of PMO-based oligomers.
