BUFFALO, NY -- (Marketwire) -- 08/13/08 -- Cleveland BioLabs, Inc. (NASDAQ: CBLI) and founding partner Cleveland Clinic reported today that CBLI's lead product, Protectan CBLB502, currently being developed as a radioprotectant and radiomitigator, demonstrated efficacy in animal models of tourniquet injury. This finding is the result of pre-clinical studies funded by a grant from the Department of Defense to research the use of Protectans in tourniquet and other ligation-reperfusion battlefield injuries, where blood flow is stopped and then restored after a prolonged period of time.

Tourniquet injury is also frequently associated with natural disaster conditions, as well as during other situations involving limb wounds or trauma. This injury is caused by prolonged deficit of oxygen supply, or ischemia, followed by rapid onset of oxidative stress at the time of tourniquet removal and results in irreversible tissue damage. Such damage often necessitates amputation of the limbs, which has restricted the use of this otherwise life saving device.

"The effect of CBLI's compound on limb recovery in our animal model of tourniquet-induced injury is encouraging and the efficacy with which it protects warrants continued investigation," said Robert Fairchild, Ph.D., of Cleveland Clinic's Lerner Research Institute. "These results will allow us to project the potential use of this compound for multiple applications beyond tourniquet injury -- from kidney and heart ischemia to reducing the rapid inflammation normally observed in transplanted organs, exploring all situations with similar mechanisms of tissue injury."

In an animal model of tourniquet-mediated limb injury simulating the situation occurring in humans, it has been demonstrated that injection of Protectan CBLB502 within 30 minutes of tourniquet removal leads to a marked reduction in the severity of injury, including reductions in tissue edema, pro-inflammatory cytokine production and leukocyte infiltration leading to accelerated recovery of limb function.

"The fact that Protectan CBLB502 demonstrated results even after the removal of a tourniquet, could make it particularly practical for battlefield conditions or other types of civilian emergency use, since it can be applied after an injured subject is delivered to the site of treatment," said Andrei Gudkov, Ph.D, D. Sci., Chief Scientific Officer of Cleveland BioLabs and inventor of the technology.
