Cleveland BioLabs Announces Approval to Start Phase 1 Study for Hematopoietic Stem Cell Mobilizer CBLB612 in Russian Federation

BUFFALO, NY--(Marketwired - Sep 15, 2014) - Cleveland BioLabs, Inc. (NASDAQ: CBLI) today announced approval from the Ministry of Health of the Russian Federation to start a Phase 1 clinical trial with CBLB612, a drug in development for the induction and mobilization of hematopoietic stem cells (HSC).

The study will be conducted in healthy subjects and is planned to start in the fourth quarter of 2014. The objectives of the study include establishing a maximally tolerated dose, evaluating the safety profile and pharmacokinetics of CBLB612, and characterizing the type, quantity and timing of HSC mobilization. This study is partially funded through a contract from the Ministry of Industry and Trade of the Russian Federation.

CBLB612's demonstrated preclinical activity as an inducer and mobilizer of HSC makes it a candidate for potential use to enhance collection of HSC for use in transplantation. HSC are commonly mobilized into the circulating peripheral blood and then collected from the donor through leukapheresis. Injections of mobilizing drugs are commonly used to increase HSC yield in this process.

Studies in mice and non-human primates have shown that a single administration of CBLB612 induces a greater concentration of HSC in peripheral blood in experimental animals than currently available mobilizing drugs. These studies have also revealed a potent synergistic effect on the mobilization of HSC in these species when CBLB612 is combined with these current standard-of-care agents. An improved mobilizing regimen could increase the numbers of mobilized HSC, potentially minimizing the need for leukapheresis from the donor and enhancing bone marrow recovery in the recipient.
