Cleveland BioLabs and Roswell Park Cancer Institute Announce Award of Department of Defense Breast Cancer Research Program Breakthrough Grant for Entolimod


BUFFALO, NY--(Marketwired - Apr 27, 2015) - Cleveland BioLabs, Inc. (NASDAQ: CBLI) and Roswell Park Cancer Institute (RPCI) today announced the award of a three-year, $1.2 million Breast Cancer Research Program Breakthrough Award to Roswell Park from the Department of Defense Congressionally Directed Medical Research Program for research into the immunotherapy of metastatic breast cancer with entolimod, a toll-like receptor 5 (TLR5) agonist. The intent of the Breakthrough Award is to support promising research that has potential to lead to or make breakthroughs in breast cancer therapy.

Breast cancer is one of the most common cancers in women worldwide.1 Nearly 50% of women diagnosed with breast cancer will progress to liver and lung metastatic disease.2 The 5-year survival rate for metastatic breast cancer is currently estimated at less than 25%.3 Current anti-cancer therapies show limited efficacy against metastatic breast cancer and often display significant toxicities. Entolimod, a proprietary investigational drug being developed by CBLI, has shown preclinical potential in the immunotherapy of cancer, including models of liver metastases. Entolimod administration activates innate and adaptive immune responses and mobilizes immunocytes to organs and tumors that express entolimod's target, TLR5.

A Phase 1 open-label, dose-escalation trial of entolimod in patients with advanced cancer was completed in September 2014 at Roswell Park Cancer Institute. Findings will be presented during the Developmental Therapeutics - Immunotherapy poster session at the 2015 annual meeting of the American Society of Clinical Oncology (ASCO) on May 30, 2015. A second Phase 1 study of entolimod in patients with advanced cancer is enrolling in the Russian Federation to expand upon clinical observations made at the higher dose levels in the RPCI study and to gather further statistics on immune response to administrations of entolimod.

Andrei Gudkov, Ph.D., D.Sci., Senior Vice President of Basic Science at Roswell Park Cancer Institute, Chief Scientific Officer of Cleveland BioLabs, and Principal Investigator on the grant, stated, "We are honored to be among less than 5% of the highest scored applications awarded with this very competitive grant and are excited to further our research into the potential utility of entolimod in treating breast cancer. We expect that the Breakthrough Award will support several avenues of research, including characterization of the immune response elicited by administrations of entolimod in a pre-clinical model of metastatic breast cancer and in patients with metastatic breast cancer being enrolled in an ongoing clinical study in the Russian Federation. We also plan to explore entolimod's ability to improve the therapeutic efficacy of a tumor-specific dendritic cell vaccine in animal models."
