ClinConnect Summary
This clinical trial is studying a new treatment called Edaravone Dexborneol Sublingual Tablets for patients who have had an acute ischemic stroke caused by small vessel disease. The trial aims to find out if this treatment can help improve recovery and brain function in people who have experienced a specific type of stroke known as a recent small subcortical infarct. Researchers will enroll about 600 participants, aged 30 to 80 years, and will randomly assign them to receive either the study medication or a placebo (a harmless pill with no active ingredients) for 24 weeks. After the treatment period, participants will be followed for an additional 28 weeks to assess their progress.
To be eligible for the trial, participants must be between 30 and 80 years old and have had a stroke confirmed by an MRI scan within the last three weeks. They should also have good pre-stroke function and no history of significant cognitive impairment. Participants can expect to complete various assessments to measure their health and cognitive abilities throughout the study. It's important to note that certain medical conditions and treatments may exclude someone from participating. Overall, this trial is an important step in exploring new options for improving recovery after strokes related to small vessel disease.

- • 15. Pregnancy and Lactation:Pregnant or lactating women, or those planning pregnancy during the study period.
- • 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.
