Rationale: MultiStem® (HLM051) is one of the promising allogenic cell products for acute ischemic stroke with strong evidence. A previous phase 2 randomized, double-blind, placebo-controlled, multicenter dose-escalation trial showed the safety of MultiStem® for acute ischemic stroke, with a time window beyond that of rt-PA and endovascular thrombectomy. We aim to obtain stronger evidence and to show the efficacy of the MultiStem® for treatment of ischemic stroke. Sample size: Estimated sample size is 220 (110 patients per group), which has 90% power at 5% significance level. Methods and design: TREASURE is a randomized, double-blind, placebo-controlled, multicenter phase 2/3 trial. The trial will be done at 31 medical centers in Japan. Patients with acute ischemic stroke including motor or speech deficit defined by a National Institution of Health Stroke Scale (NIHSS) score of 8-20 at baseline will be randomized 1:1 to receive a single intravenous infusion of MultiStem® or placebo within 18-36 h of stroke onset. Study outcomes: Primary outcome in this study is the proportion of patients with an excellent outcome at day 90 defined by the functional assessment. Trial registration: ClinicalTrials.gov (NCT02961504). Conclusion: The TREASURE trial will provide a novel treatment option and expand the therapeutic window for patients with stroke if the results are positive.
