ClinConnect Summary

This clinical trial is studying a new treatment called edaravone dexborneol sublingual tablets to see if it can help improve thinking and memory problems (known as post-stroke cognitive impairment) in patients who have recently had an ischemic stroke, which is a type of stroke caused by blocked blood flow to the brain. The trial will involve participants taking these tablets or a placebo (a non-active treatment) for 24 weeks. Researchers want to find out if the tablets are safe and effective compared to the placebo.

To join the trial, participants need to be between 40 and 80 years old, have had an ischemic stroke, and show some signs of cognitive difficulties, but they should not have had significant cognitive issues before the stroke. They will also need to be able to complete certain cognitive tests. During the trial, participants will be monitored closely to ensure their safety and to see how well the treatment is working. This study is currently recruiting, so if you or someone you know meets the criteria, it could be an opportunity to help advance research in stroke recovery.
