Study summary
This study is a multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of Edaravone Dexborneol Sublingual Tablets in patients with acute ischemic stroke due to small vessel disease (TASTE-SVD).
The study will enroll approximately 600 participants aged 30 to 80 years who have experienced a recent small subcortical infarct (RSSI) confirmed by MRI. Participants will be randomized in a 1:1 ratio into either the Edaravone Dexborneol Sublingual Tablets group or the placebo group, with a 24-week treatment period followed by a 28-week follow-up.
The primary endpoint is a hierarchical composite endpoint at week 24, including all-cause mortality, modified Rankin Scale (mRS) score ≥2, recurrent stroke, changes in MoCA score, and changes in VaDAS-Cog score.
Secondary endpoints include additional functional and cognitive assessments at 24 and 52 weeks, as well as MRI markers of white matter hyperintensities, new infarctions, microbleeds, and brain atrophy. Safety assessments will include adverse events (AEs), treatment-related adverse events (TRAEs), and serious adverse events (SAEs).
The study aims to determine whether Edaravone Dexborneol Sublingual Tablets improve functional outcomes and cognitive performance in patients with small vessel disease-related stroke.

16. Participation in Other Clinical Trials:Enrolled in another clinical trial within the last 30 days.
17. Other Investigator-Determined Factors:Any other medical, psychological, or social condition that, in the investigator's judgment, makes the patient unsuitable for participation.
Primary outcome measure(s)
- Hierarchical Composite Endpoint — 24 weeks
This composite outcome consists of five hierarchical endpoints at 24 weeks, analyzed using the Win Ratio method:
1. All-Cause Mortality
2. Modified Rankin Scale (mRS) Score ≥2
3. Stroke Recurrence
4. Change in Montreal Cognitive Assessment (MoCA) Score from Baseline
5. Change in Vascular Dementia Assessment Scale-Cognitive Subscale (VaDAS-Cog) Score from Baseline The Win Ratio approach will be used to analyze these outcomes in order of priority.
- All-Cause Mortality — 24weeks
The number of participants who experience all-cause mortality at 24 weeks. All-cause mortality includes death from any reason, such as cardiovascular, neurological, or other systemic causes. This measure is used to assess the overall survival impact of the intervention.
- Modified Rankin Scale (mRS) Score ≥2 — 24 weeks
The proportion of participants with a modified Rankin Scale (mRS) score ≥2 at 24 weeks. The mRS is a widely used functional outcome measure that assesses the degree of disability or dependence in daily activities following a stroke. The scale ranges from 0 (no symptoms) to 6 (death), with scores of 2 or higher indicating functional dependence. A higher proportion of participants with mRS ≥2 suggests a worse functional outcome.
- Stroke Recurrence — 24 weeks
The number of participants who experience a recurrent stroke within 24 weeks of treatment. Recurrent stroke is defined as a new ischemic or hemorrhagic stroke occurring after the initial qualifying event, confirmed by neurological symptoms lasting ≥24 hours and neuroimaging evidence (MRI or CT). This measure assesses the effectiveness of the intervention in preventing subsequent strokes
- Change in Montreal Cognitive Assessment (MoCA) Score from Baseline — 24 weeks
The change in Montreal Cognitive Assessment (MoCA) scores from baseline to 24 weeks of treatment. The MoCA is a cognitive screening tool that assesses multiple domains, including attention, concentration, executive function, memory, language, visuospatial skills, abstract thinking, calculation, and orientation. Scores range from 0 to 30, with higher scores indicating better cognitive function. A greater positive change from baseline represents an improvement in cognitive function.
- Change in Vascular Dementia Assessment Scale-Cognitive Subscale (VaDAS-Cog) Score from Baseline — 24 weeks
The change in Vascular Dementia Assessment Scale-Cognitive Subscale (VaDAS-Cog) score from baseline to 24 weeks of treatment. The VaDAS-Cog is a neuropsychological assessment tool specifically designed to evaluate cognitive impairments associated with vascular dementia. VaDAS-Cog was created by adding five subtests to the ADAS-Cog that reflect attention and executive functions. The total score ranges from 0 to 70, with lower scores indicating lesser severity.
