Edaravone Dexborneol for Post-Stroke Epilepsy

Starting soon · Phase 3 · Has a placebo group

Conditions studied: Post-stroke Epilepsy, Post-stroke Seizure

In brief

This is a prospective, randomized, double-blind, placebo-controlled, multicenter clinical trial designed to evaluate the efficacy and safety of Edaravone Dexborneol sublingual tablets in preventing late-onset epilepsy in patients with acute ischemic stroke at high risk. Eligible participants are adults aged 18-80 years with a confirmed diagnosis of acute ischemic stroke by clinical and imaging criteria (MRI or CT), enrolled within 48 hours of stroke onset. High risk for post-stroke epilepsy is defined as a SeLECT-EEG score ≥7. Patients must have no prior history of epilepsy or other central nervous system disorders associated with seizures. Key exclusion criteria include prior seizures before enrollment, recent stroke within the past 12 months, severe renal or hepatic dysfunction, significant cardiac insufficiency, drug hypersensitivity, pregnancy or lactation, and other conditions deemed unsuitable by investigators. A total of approximately 160 participants will be randomized in a 1:1 ratio to receive either Edaravone Dexborneol sublingual tablets or matching placebo. The primary endpoint is a composite outcome assessed within 2 years, defined as the occurrence of either: (1) definite clinical epileptic seizures, or (2) new-onset or worsening epileptiform EEG abnormalities (including IEDs, PDs, LRDAs) or electrographic seizures. Secondary endpoints include: incidence of individual components of the primary outcome; time to first seizure; characteristics, severity, and frequency of seizures; longitudinal changes and resolution rate of epileptiform EEG activity; cognitive function assessed by MoCA and MMSE; neurological outcomes evaluated by mRS and NIHSS; quality of life and functional independence measured by SSQOL and Barthel Index; recurrence of stroke and all-cause mortality; changes in inflammatory biomarkers (TNF-α, IL-1β, COX-2, iNOS); and safety outcomes including treatment-emergent adverse events, serious adverse events, laboratory abnormalities, and treatment discontinuation due to adverse events. All efficacy and safety outcomes will be independently reviewed by a blinded adjudication committee. Statistical analyses will include chi-square or Fisher's exact tests for categorical outcomes, Kaplan-Meier survival analysis with log-rank tests for time-to-event data, and Cox proportional hazards models to adjust for potential confounders. The study period is planned from June 2026 to June 2030.
