Background And Purpose

DL-3-n-butylphthalide (NBP) is a drug for treating acute ischemic stroke and may play a neuroprotective role by acting on multiple active targets. The efficacy of NBP in patients with acute ischemic stroke receiving reperfusion therapy remains unknown.

Method

This multicenter, double-blind, placebo-controlled, parallel randomized clinical trial was conducted in 59 centers in China with 90-day follow-up. Of 1236 patients with acute ischemic stroke, 1216 patients 18 years and older diagnosed with acute ischemic stroke with a National Institutes of Health Stroke Scale score ranging from 4 to 25 who could start the trial drug within 6 hours from symptom onset and received either intravenous recombinant tissue plasminogen activator (rt-PA) or endovascular treatment or intravenous rt-PA bridging to endovascular treatment were enrolled, after excluding 20 patients who declined to participate or did not meet eligibility criteria. Data were collected from July 1, 2018, to May 22, 2022.

Conclusion

Among patients with acute ischemic stroke receiving intravenous thrombolysis and/or endovascular treatment, NBP was associated with a higher proportion of patients achieving a favorable functional outcome at 90 days compared with placebo.

Main results

Of 1216 enrolled patients, 827 (68.0%) were men, and the median (IQR) age was 66 (56-72) years. A total of 607 were randomly assigned to the butylphthalide group and 609 to the placebo group. A favorable functional outcome at 90 days occurred in 344 patients (56.7%) in the butylphthalide group and 268 patients (44.0%) in the placebo group (odds ratio, 1.70; 95% CI, 1.35-2.14; P < .001). Serious adverse events within 90 days occurred in 61 patients (10.1%) in the butylphthalide group and 73 patients (12.0%) in the placebo group.
