Cleveland BioLabs, Inc. (NASDAQ: CBLI) (BOST: CBLI) today announced that the Company's application for upgrade of its listing from NASDAQ Capital Market to NASDAQ Global Market was approved. The Company's shares will begin trading on NASDAQ Global Market under the same symbol (CBLI), effective August 28, 2007.

Following July 3, NASDAQ-listed companies are classified under three listing tiers -- NASDAQ Global Select Market, NASDAQ Global Market, and NASDAQ Capital Market. NASDAQ announced the new three tier listing classification in February 2006. All three market tiers maintain rigorous listing and corporate governance standards.

Cleveland BioLabs currently has two lead compounds in late stages of development. Curaxin CBLC102 is an orally administered small molecule designed to kill tumor cells by simultaneously targeting two key regulators of apoptosis. The Company has an ongoing Phase II trial with CBLC102 in hormone refractory prostate cancer.

The Company's other lead compound, Protectan CBLB502, is a modified protein of a microbe that temporarily protects cells from regulated cell death. CBLB502 is the first compound of its kind to provide protection from both gastrointestinal and hematopoietic (bone marrow/blood production) radiation-induced damage. CBLB502 is being developed initially as a radiation antidote for the military, rescue workers, nuclear plant personnel and eventually for all people who may be subject or vulnerable to nuclear attack or accident. Other applications for this technology include protection from cancer treatment side effects and acute organ failure.

Earlier this year, the Company submitted CBLB502 to the Department of Defense (DoD) in response to a Request for Proposal (RFP) for medical radiation countermeasures to treat gastrointestinal effects of acute radiation syndrome. The RFP award would provide funding for development of the countermeasure through FDA approval, as well as a commitment to purchase up to 500,000 doses, thereafter. The Company expects the DoD to make its decision on the RFP later this year.
