Panacela Signs Contract for Approximately $4.6 Million With Russian Ministry
of Industry and Trade for Development of Mobilan; Announces Appointment of
Michael Fonstein as CEO and President

BUFFALO, N.Y., Oct. 23, 2013 (GLOBE NEWSWIRE) -- Cleveland BioLabs, Inc.
(Nasdaq:CBLI) today announced that Panacela Labs, Inc., a majority-owned
subsidiary of CBLI, has entered into a contract valued at approximately 149
million rubles, or approximately $4.6 million, with the Ministry of Industry
and Trade of the Russian Federation for development of Mobilan, a cancer
vaccine in preclinical development. Under the contract, the Russian Federation
has agreed to match Panacela's funding of Mobilan over a period of
approximately three years, for support of preclinical and clinical studies.

Mobilan is a recombinant adenovirus which expresses both toll-like receptor 5
(TLR5) and its agonistic ligand. Administration of Mobilan in animal models
leads to constitutive autocrine stimulation of TLR5 signaling causing strong
induction of the innate immune system with subsequent development of adaptive
anti-tumor immune responses.

Panacela also announced the appointment of Michael Fonstein, Ph.D. as Chief
Executive Officer and President replacing, Dmitry Tyomkin, who was recently
appointed Chief Executive Officer of Buffalo BioLabs, LLC, a laboratory and
preclinical services company.

"This is Panacela's second development contract with the Russian Ministry of
Industry and Trade," noted Dr. Fonstein. "Our goal is to advance two of our
product candidates into the clinic in the coming year. We are honored to
partner with the Ministry to support a substantial part of our clinical
development program."
