Edaravone Dexborneol for Post-Stroke Epilepsy
A Randomized, Double-blind, Placebo-controlled, Multicenter Clinical Study of Edaravone Dexborneol Sublingual Tablets for the Prevention of Post-Stroke Epilepsy
Source: ClinicalTrials.gov · Last updated 22 May 2026
Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- 2\. History of ischemic or hemorrhagic stroke within 12 months prior to the index stroke.
Other illness
- 3\. Large cerebral infarction with severe intracranial hypertension on imaging after stroke, with limited life expectancy or inability to complete follow-up.
- 6\. Known hypersensitivity to edaravone or borneol, or a history of severe drug allergy.
- 8\. Presence of other serious diseases (e.g., advanced malignancy) that may affect survival or study compliance.
- 9\. Any other condition that, in the investigator's judgment, makes the patient unsuitable for participation in the study.
Lab values
- 4\. Severe renal impairment (significantly reduced eGFR according to contraindications of edaravone dexborneol) or a history of edaravone-related renal injury.
- 5\. Severe hepatic dysfunction (ALT or AST \>3 times the upper limit of normal) or severe heart failure (New York Heart Association class III-IV) that may preclude tolerance to the study drug.
Other
- 7\. Pregnant or breastfeeding women; women of childbearing potential unwilling to use effective contraception.
Who the study is looking for
- 2\. Diagnosis of acute ischemic stroke confirmed by clinical presentation and neuroimaging (MRI or CT).
- 3\. Time from stroke onset to screening/randomization ≤48 hours.
- 4\. High risk of post-stroke epilepsy, defined as a SeLECT-EEG score ≥7, including: stroke severity (Se, 0-2 points), large-artery atherosclerosis etiology (L, 0-1 point), cortical involvement (C, 0-2 points), middle cerebral artery territory infarction (T, 0-1 point), and EEG findings (EEG, 0-2 points).
- 5\. No prior history of epilepsy before the index stroke, and no history of other central nervous system disorders (e.g., traumatic brain injury, brain tumor) associated with seizures.
- 6\. Conscious at enrollment or with recovered consciousness after treatment, and able to cooperate with sublingual medication administration and follow-up assessments.
- 7\. Provision of written informed consent by the patient or a legally authorized representative.
