Stem Cell Therapeutics Announces Favorable Results From the Phase IIa BETAS Stroke Trial

CALGARY, ALBERTA--(Healthcare Sales & Marketing Network)--Feb 20, 2008 -- Stem Cell Therapeutics Corp. ("SCT") (CDNX:SSS.V ) is pleased to announce favorable results from the investigator led BETAS (Beta-hCG + Erythropoietin in Acute Stroke), Phase IIa, open label, safety trial conducted at the University of California, Irvine and Hoag Presbyterian Memorial Hospital, Newport Beach, CA. This trial is the first to test the safety of NTx(TM)-265 in patients suffering acute ischemic stroke and to conduct a preliminary assessment of functional recovery in this patient population.

Results from the BETAS trial showed no serious adverse events related to NTx(TM)-265 in the 13 patients enrolled. Of these, 8 patients completed the 90 day assessment term and each of them showed a clinically relevant improvement in their National Institutes of Health Stroke Scale (NIHSS) score of 4 points or greater. Patients entered the trial with NIHSS scores ranging from 6-19 (moderate to severe). In these patients, average baseline NIHSS was 8.3 plus/minus 4.1 (mean plus/minus SD) and improved in 8 of 8 patients to an average day 90 NIHSS of 2.5 plus/minus 1.8, an improvement in NIHSS score of 5.8 plus/minus 2.5 points. Five of these 8 patients had a day 90 Barthel Index score of 95-100 (out of 100); consistent with excellent outcome. Specific assessments of neurological recovery affected by NTx(TM)-265 were also favorable, including the Arm Motor Fugl-Meyer Scale, an arm motor recovery assessment; Trailmaking A test, a measure of cognitive function; and measures of neglect and aphasia. Further, the drug regimen decreased the size of the infarct in 6 out of 8 patients overall, given a mean decrement in all 8 of about 10%.

Dr. Alan Moore, President and CEO of SCT, commented as follows:

"The encouraging results from this trial are consistent with results previously reported as an interim analysis on April 10, 2007 and suggest great promise for our NTx(TM)-265 treatment for stroke, but interpretation of results from the BETAS trial is limited by small patient sample size and absence of a placebo control group. Nevertheless, these results represent an important first step in defining the safety of the NTx(TM)-265 regimen in patients with acute neurologic injury. Equally promising is early evidence in a small group of patients that consistent recovery of motor, cognitive and visual function may occur as a result of NTx(TM)-265 neuro-regenerative therapy for stroke."

The next development step for SCT is to build upon the promising results from the BETAS clinical trial with the initiation of the REGENESIS proof of concept study. REGENESIS is a Phase IIb prospective, randomized, double-blind, placebo controlled study of NTx(TM)-265: human Chorionic Gonadotropin (hCG) and epoetin alfa (EPO) in acute ischemic stroke patients. The REGENESIS trial will be conducted at approximately 15-20 Canadian clinical trial centers and aims to enroll 134 patients in 2008.

The BETAS clinical data will be formally presented at the International Stroke Conference in New Orleans, LA, February 20-22, 2008. SCT will also be hosting a live audio webcast to review the results with Dr. Steven Cramer on Tuesday February 26, 2008.

About NTx(TM)-265: NTx(TM)-265 is a therapeutic regimen of two approved and clinically well-defined drugs, human Chorionic Gonadotropin (hCG) and Erythropoietin (EPO), targeting the treatment of stroke. The objective of the regimen is to stimulate the growth and differentiation of new neurons to replace the brain cells that were lost or damaged by the stroke. Animal studies have shown a significant recovery in motor function after receiving the NTx(TM)-265 regimen 24-48 hours post stroke. Similar results have been found in SCT's Phase IIa BETAS safety trial, as announced on April 10, 2007. SCT has initiated a multi-centre, double-blind, placebo-controlled Phase IIb REGENESIS study for NTx(TM)-265 with primary endpoints of efficacy.
