CLEVELAND February 17, 2016 (GLOBE NEWSWIRE) -- Athersys, Inc. (Nasdaq:ATHX) today announced positive results from the analysis of one-year follow-up data from its Phase 2 clinical study of the intravenous administration of MultiStem® cell therapy to treat patients who have suffered an ischemic stroke. Dr. David Hess, lead clinical investigator of this study and a stroke specialist and Chairman of the Department of Neurology at the Medical College of Georgia, Augusta University, presented the summary results today at the 2016 International Stroke Conference in Los Angeles. The one-year data demonstrates that MultiStem-treated subjects on average continued to improve through one year and had a significantly higher rate of "Excellent Outcome" (defined clinically as attaining mRS 0-1, NIHSS 0-1 and BI ≥95) compared to placebo subjects at one year when evaluating all subjects enrolled in the study (p=0.02), i.e., the intent-to-treat population. The relative improvement in Excellent Outcomes was even more pronounced in the patients who received MultiStem treatment within 36 hours of the stroke (p < 0.01).
