Cleveland BioLabs Announces Green Light to Submit Pre-Emergency Use Authorization Application for Entolimod

BUFFALO, NY--(Marketwired - Sep 3, 2014) - Cleveland BioLabs, Inc. (NASDAQ: CBLI) today announced that the minutes from its meeting with the U.S. Food and Drug Administration (FDA) in July confirmed that the Company's existing efficacy and safety data and animal-to-human dose conversion are sufficient to proceed with a pre-Emergency Use Authorization (pre-EUA) submission for entolimod for reducing the risk of death following exposure to potentially lethal irradiation occurring as the result of a radiation disaster.

Yakov Kogan, Ph.D, MBA, Chief Executive Officer of Cleveland BioLabs, stated, "The outcome of our FDA meeting is very positive and we are pleased with the agreements we have reached with the agency. Our achievement of animal-to-human dose conversion and the FDA's acknowledgement of the conceptual soundness of our dose-conversion methods are significant milestones in entolimod's development under the FDA's Animal Rule."

"We are starting preparations for a pre-EUA application which, if authorized, would allow for entolimod's use in the event of a radiological or nuclear emergency. In parallel, we are continuing our discussions with various U.S. government agencies regarding potential co-sponsorship and support for a pre-EUA submission for entolimod, as well as ongoing funding for the remaining development steps required for full licensure. We believe that entolimod has enormous potential to save lives as part of the nation's defense against a radiological or nuclear disaster and are dedicated to moving its development forward."

A pivotal efficacy study conducted in 179 non-human primates (NHPs) demonstrated that a single intramuscular injection of entolimod given 25 hours after high-dose, whole-body irradiation increased survival from 27.5% in control animals to 75% in treated animals -- a highly statistically significant, nearly three-fold improvement. These results were obtained without the use of any antibiotics or supportive care. A second, pivotal dose-conversion study conducted in 160 NHPs established the dose-dependent effect of entolimod on biomarkers for efficacy in non-irradiated NHPs.

Clinical studies of entolimod in 150 healthy human subjects have demonstrated the safety profile of entolimod and established the dose-dependent effect of entolimod on efficacy biomarkers in humans. In addition, entolimod has been administered to 25 patients with advanced cancer in an ongoing Phase 1 study.

The FDA has granted Fast Track status to entolimod and Orphan Drug status for prevention of death following a potentially lethal dose of total body irradiation during or after a radiation disaster.
