Summary

This study is a multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the long-term efficacy and safety of butylphthalide in patients with minor acute ischemic stroke (BLESS Trial).

A total of 1200 participants aged 40 to 80 years with a minor acute ischemic stroke confirmed by MRI will be enrolled. Participants will be randomly assigned in a 1:1 ratio to receive butylphthalide or placebo for 12 months.

The primary outcome is a hierarchical composite endpoint assessed at 12 months, including:

1. All-cause mortality
2. Stroke recurrence
3. Modified Rankin Scale (mRS) score ≥2
4. New MRI-confirmed infarcts
5. Change in Montreal Cognitive Assessment (MoCA) score from baseline

Secondary outcomes include additional functional, cognitive, and imaging-based assessments at 12 months.

This study aims to determine whether butylphthalide can improve long-term functional and cognitive outcomes in patients with minor ischemic stroke, contributing to better secondary stroke prevention strategies.

Conditions

Interventions

DRUG

Butylphthalide

Butylphthalide (NBP) is a neuroprotective agent derived from celery seed. It has demonstrated potential benefits in improving microcirculation, reducing oxidative stress, and protecting against neuronal injury in ischemic stroke. This study uses butylphthalide soft capsules (200 mg per dose) administered orally, three times daily for 12 months, to evaluate its long-term efficacy and safety in patients with minor acute ischemic stroke

DRUG

Placebo

Matching placebo soft capsules, identical in appearance to butylphthalide capsules, administered orally at a dose of one capsule (200 mg equivalent) three times daily for 12 months. The placebo contains inactive ingredients without pharmacological effects and is used as a control to assess the efficacy and safety of butylphthalide in patients with minor acute ischemic stroke.
