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.
