Background and Purpose— Previous clinical studies suggested benefit for poststroke recovery when MLC601 was administered between 2 weeks and 6 months of stroke onset. The Chinese Medicine Neuroaid Efficacy on Stroke recovery (CHIMES) study tested the hypothesis that MLC601 is superior to placebo in acute, moderately severe ischemic stroke within a 72-hour time window. Methods— This multicenter, double-blind, placebo-controlled trial randomized 1100 patients with a National Institutes of Health Stroke Scale score 6 to 14, within 72 hours of onset, to trial medications for 3 months. The primary outcome was a shift in the modified Rankin Scale. Secondary outcomes were modified Rankin Scale dichotomy, National Institutes of Health Stroke Scale improvement, difference in National Institutes of Health Stroke Scale total and motor scores, Barthel index, and mini-mental state examination. Planned subgroup analyses were performed according to age, sex, time to first dose, baseline National Institutes of Health Stroke Scale, presence of cortical signs, and antiplatelet use. Results— The modified Rankin Scale shift analysis–adjusted odds ratio was 1.09 (95% confidence interval, 0.86–1.32). Statistical difference was not detected between the treatment groups for any of the secondary outcomes. Subgroup analyses showed no statistical heterogeneity for the primary outcome; however, a trend toward benefit in the subgroup receiving treatment beyond 48 hours from stroke onset was noted. Serious and nonserious adverse events rates were similar between the 2 groups. Conclusions— MLC601 is statistically no better than placebo in improving outcomes at 3 months when used among patients with acute ischemic stroke of intermediate severity. Longer treatment duration and follow-up of participants with treatment initiated after 48 hours may be considered in future studies. Clinical Trial Registration— URL: http://www.clinicaltrials.gov.

Background and Purpose— Early vascular events are an important cause of morbidity and mortality in the first 3 months after a stroke. We aimed to investigate the effects of MLC601 on the occurrence of early vascular events within 3 months of stroke onset. Methods— Post hoc analysis was performed on data from subjects included in the CHInese Medicine Neuroaid Efficacy on Stroke recovery (CHIMES) study, a randomized, placebo-controlled, double-blinded trial that compared MLC601 with placebo in 1099 subjects with ischemic stroke of intermediate severity in the preceding 72 hours. Early vascular events were defined as a composite of recurrent stroke, acute coronary syndrome, and vascular death occurring within 3 months of stroke onset. Results— The frequency of early vascular events during the 3-month follow-up was significantly less in the MLC601 group than in the placebo group (16 [2.9%] versus 31 events [5.6%]; risk difference=−2.7%; 95% confidence interval, −5.1% to −0.4%; P=0.025) without an increase in nonvascular deaths. Kaplan–Meier survival analysis showed a difference in the risk of vascular outcomes between the 2 groups as early as the first month after stroke (Log-rank P=0.024; hazard ratio, 0.51; 95% confidence interval, 0.28–0.93). Conclusions— Treatment with MLC601 was associated with reduced early vascular events among subjects in the CHIMES study. The mechanisms for this effect require further study.

Stroke is a major cause of morbidity and mortality in Asia, and its pattern is changing. The incidence of haemorrhagic stroke is declining while the incidence of ischaemic stroke caused by large artery atherothromboembolism is increasing secondary to an increase in the prevalence of hypercholesterolemia. The Working Group on Stroke and Lipids Management in Asia Consensus Panel assembled leading experts from the region to reach a consensus on how to address this challenge. The group discussed the observational epidemiology of the relationship between cholesterol and risk of stroke, the clinical trial evidence base for cholesterol-lowering for stroke prevention, and issues specific to stroke and lipid management for Asian doctors and patients. Stroke guidelines from many of the Asian countries have recently recommended consideration of statins for recurrent stroke prevention in patients with previous ischaemic stroke or transient ischaemic attack. However, because these recommendations have yet to be
