Cleveland BioLabs and Incuron Announce Notice of Allowance From FDA to
Commence Clinical Testing With CBL0137

BUFFALO, N.Y., April 2, 2013 (GLOBE NEWSWIRE) -- Cleveland BioLabs, Inc.
(Nasdaq:CBLI) and Incuron, LLC, a joint venture between the Company and
Bioprocess Capital Ventures, today announced the receipt of a Notice of
Allowance from the U.S. Food and Drug Administration (FDA) for an
Investigational New Drug (IND) application for CBL0137.

A multi-center, Phase 1, single agent, dose escalation trial evaluating
intravenous administration of CBL0137 in patients with metastatic or
unresectable advanced solid cancers is being finalized with the FDA. The
primary objective of the study is to determine the maximally tolerated dose
and recommend a Phase 2 dose for CBL0137 in these patients. Secondary
objectives include describing the dose limiting toxicity, adverse event and
pharmacokinetic profile of CBL0137, as well as documenting any objective
responses.Exploratory objectives for the study include examining the
relationship between tumor expression of Facilitates Chromatin Transcription
(FACT), the molecular target of CBL0137, tumor response and the effect of
CBL0137 on FACT expression in peripheral blood mononuclear cells and on
soluble factors in serum.

A Phase 1, single agent, dose escalation study of oral administration of
CBL0137 in patients with advanced solid tumors that are resistant or
refractory to standard of care treatment is ongoing in the Russian Federation.

Yakov Kogan, Ph.D., MBA, Chief Executive Officer of CBLI, commented, "We are
pleased to announce the opening of an IND for CBL0137 in the U.S.Our recently
expanded knowledge regarding FACT expression in tumors and the potential
ability to obtain additional data on CBL0137's impact on FACT expression
through initial trials in US and Russia will be invaluable as we plot the
future clinical development of CBL0137."
