CAMBRIDGE, MA, USA I September 30, 2014 I Sarepta Therapeutics, Inc. (NASDAQ: SRPT), a developer of innovative RNA-based therapeutics, today announced favorable safety results from the single ascending dose portion of a Phase I study of AVI-7100, the company’s lead candidate for the treatment of influenza virus, in healthy volunteers. The clinical trial is being conducted at the National Institutes of Health (NIH) through a collaboration between the company and the NIH’s National Institute of Allergy and Infectious Diseases. AVI-7100 uses Sarepta’s advanced and proprietary PMOplus™ chemistry, which is also the basis of the company’s clinical-stage Ebola and Marburg drug candidates.
The Phase I clinical study is a randomized, double-blind, placebo-controlled trial designed to characterize the safety, tolerability and pharmacokinetics of single and multiple doses of an intravenous formulation of AVI-7100 in healthy adult volunteers. In the completed single ascending dose portion, 40 subjects were enrolled in five cohorts (6 active: 2 placebo) up to the highest dose tested of 8 mg/kg AVI-7100. Results showed that AVI-7100 was well-tolerated with no reported serious or clinically significant adverse events. The pharmacokinetic analysis of AVI-7100 reveals a highly similar dose-dependent profile to that of Sarepta’s Ebola and Marburg PMOplus™ drug candidates. An independent Data and Safety Monitoring Board reviewed safety results from the study and recommended the study continue as planned to the multiple dose portion of the study.
“We are very encouraged that our partnership with NIH is generating new favorable clinical safety data, adding to a growing body of evidence supporting the safety of Sarepta’s PMO-based chemistry platform across a broad range of disease targets,” said Chris Garabedian, president and chief executive officer of Sarepta Therapeutics. “The similar drug-like characteristics demonstrated across a broad spectrum of targets offers a versatility that will be especially critical in developing a capability to rapidly respond and adapt to real-world, global health threats – whether that is an Ebola outbreak, an influenza pandemic, or a never-before-seen emerging infectious disease.”
AVI-7100 utilizes a novel mechanism of action to target a well-conserved region of the influenza A virus, affording it the potential to act as a broad-spectrum treatment for multiple influenza strains, including Tamiflu-resistant flu strains. Seasonal influenza (H3N2) and 2009 H1N1 are both caused by the influenza A virus. Preclinical studies funded by the U.S. Department of Defense demonstrated that AVI-7100 improved clinical symptoms and reduced viral titers in animal models infected with pandemic H1N1 or H3N2 viruses, and had statistically significant activity as compared to saline and Tamiflu controls.
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.
About Sarepta Therapeutics
Sarepta Therapeutics is focused on developing first-in-class RNA-based therapeutics to improve and save the lives of people affected by serious and life-threatening rare and infectious diseases. The Company’s diverse pipeline includes its lead program eteplirsen and follow-on drug candidates, for Duchenne muscular dystrophy, as well as potential treatments for some of the world’s most lethal infectious diseases. Sarepta aims to build a leading, independent biotech company dedicated to translating its RNA-based science into transformational therapeutics for patients who face significant unmet medical needs.
