Cleveland BioLabs Founding Partner Cleveland Clinic Receives Department of Defense Grant to Study Protectans CBLB502 and CBLB612 for Tourniquet and Other Battlefield Uses

BUFFALO, NY--(Marketwire - November 9, 2007) - Cleveland BioLabs, Inc. (NASDAQ: CBLI) today announced that its academic and founding partner, Cleveland Clinic, received a $1 million grant from the Department of Defense to conduct pre-clinical studies on two of the Company's lead compounds, Protectan CBLB502 and Protectan CBLB612, for use in tourniquet and other ligation-reperfusion battlefield injuries where blood flow is stopped and then restored after a prolonged period of time.

The tourniquet has been used for over 300 years for effective hemorrhage control during surgery and trauma. While properly applied tourniquets are extremely effective in controlling hemorrhage, their use is far from benign. Tourniquet-related injury consists of compression injury to the underlying skin, nerve, and muscle, as well as reperfusion injury to the underlying and distal muscle and nerve. When tourniquets applied for long durations are removed, a severe systemic inflammatory response leading to damage to remote organs can take place, in some cases resulting in fatality.

Military statistics show two-thirds of all combat-related deaths are due to bleeding; and 80% of those deaths occur within 15 minutes of injury. The tourniquet is the first line of defense for the soldier in the battlefield. Statistics also show the rate of limb amputation due to battlefield arterial wounds has not improved since World War II, despite aggressive advances in surgical treatment.

To date, Protectan CBLB502 and Protectan CBLB612 have primarily been developed as radiation protectors and mitigators, due to their respective capacities to temporarily delay apoptosis, or regulated cell death, in certain tissues and thereby enable repair of damage. Apoptosis also plays a significant role in tissue injury occurring as a result of DNA damage caused by ligation-reperfusion conditions, such as those caused by tourniquet use.

CBLI researchers in collaboration with investigators from Cleveland Clinic have demonstrated that a single injection of Protectan CBLB502 effectively prevents acute renal failure and subsequent death in a mouse model of ischemia-reperfusion renal injury.

Ganes Sen, Ph.D, Principal Investigator on the grant and the Interim Chairman of the Department of Molecular Genetics at Lerner Research Institute at Cleveland Clinic, said, "We are excited to pursue additional anti-ischemia applications for Cleveland BioLabs' Protectan compounds. Their proven success in delaying apoptosis in animal models of radiation makes ligation-reperfusion injury a logical extension of their use. If we will be able to demonstrate the ability of Protectans to reduce tissue damage caused by the tourniquet and prevent excessive bleeding from wounded limbs, it may significantly broaden the use of tourniquet in the medical practice, which has been limited by the high risk of loss of limbs as a result of prolonged tissue hypoxia."

Andrei Gudkov, Ph.D, D. Sci., Chief Scientific Officer of Cleveland BioLabs and the inventor of the technology, noted, "We are eager to conduct further studies of this application for our Protectan compounds with Cleveland Clinic, which is a leader in many medical fields where ligation-reperfusion damage is commonly encountered. While the potential military use of Protectans for tourniquet and other ligation-reperfusion injuries is critical, there are multiple civilian uses in traumas such as car accidents and organ failure incurred during heart surgery. Statistics show that 50% of all civilian trauma deaths are from bleeding."

Protectan CBLB502 is undergoing an accelerated development program as the radiation antidote under the FDA two-animal rule, which requires demonstrations of efficacy in two animal species and only safety in humans. The Company plans to submit an Investigational New Drug (IND) application to the FDA for a human safety study this year.
