Stem Cell Therapeutics Announces the Publication of Key Animal Data to Support Efficacy of Its Stroke Regimen NTx(R)-265 in Brain Research (2009)

CALGARY, ALBERTA--(Marketwire - May 28, 2009) - Stem Cell Therapeutics Corp. (TSX VENTURE: SSS) (“SCT” or “the Company”) announces the acceptance and publication of a paper describing the effectiveness of the NTx®-265 stroke treatment regimen when administered 24 hours after an ischemic stroke in rats.

For the first time, this therapeutic strategy was shown to improve behavioral outcome and reduced lesion volume with a time window of 24 hours after the onset of stroke. These fundamental results provided the evidence necessary to advance NTx®-265 into the initial BETAS human stroke studies in acute ischemic stroke.

Dr. Allen Davidoff, VP of Product Development commented as follows:

“These exciting preclinical data formed the efficacy basis for our move to the clinic, and it’s encouraging to see publication of these data in a quality, peer-reviewed journal.”

The paper which is titled “A Novel Neurotrophic Therapeutic Strategy for Experimental Stroke” will appear in the scientific journal Brain Research (2009) and is currently available online.
