Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the efficacy of Y-6 sublingual tablets in improving microcirculation dysfunction and reducing thrombo-inflammation in patients who had AIS caused by LVO and received reperfusion therapy. Moreover, we expect to evaluate the safety of using Y-6 sublingual tablet in such study population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study rationale is based on the following scheme: in patients with acute ischemic stroke caused by LVO, receiving reperfusion therapy may cause futile recanalization and thus lead to microcirculation dysfunction and thrombo-inflammation as consequences. Cilostazol has antiplatelet effects and BBB protection and Dexborneol has anti-inflammatory effects; therefore, the multi-component tablet may exert neuroprotective effects in terms of improving microcirculation dysfunction and reducing thrombo-inflammation in patients with AIS after reperfusion therapy.

The primary purpose of this study is to investigate the proportion of modified-Rankin scale (mRS) score recovered to 0\~1 score at 90±7 days after randomization.

The follow-up duration is 3 months, and the visit schedule is as follows: Subjects enrolled based on randomization procedures will receive visits at screening/baseline period, first drug administration, immediately after reperfusion therapy(within 2 hours), 24 ± 2 hours, 96 ± 7 hours, 14 ± 2 days, 28 ± 2 days and 90 ± 7 days after randomization, and in case of any events.
