This is a randomized, placebo-controlled, double-blind, multicenter, phase 2/3 trial to evaluate the efficacy and safety of intravenous administration of HLCM051 compared with placebo in subjects with acute ischemic stroke (within 36 hours of onset). Japanese subjects who developed a subcortical ischemic stroke and are eligible to participate in the trial will be evaluated.~Approximately 220 subjects will be randomized in a 1:1 ratio (HLCM051 group [n=110] or placebo group [n=110]) to receive a single infusion of HLCM051 or placebo.
The primary objectives of this study is to evaluate the efficacy of HLCM051 on functional outcome in subjects with acute ischemic stroke and to evaluate the safety of HLCM051 in subjects with acute ischemic stroke.
