Clinical Trial Summary

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.

Description:

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, 24 ± 2 hours, 7 ± 2 days, 28 + 3 days and 90 ± 7 days after randomization, and in case of any events.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of mRS score recovered to 0~1 score	The modified Rankin Scale (mRS) decreasing to 0~1 score. mRS Mainly measures patients' independent living ability, including physical function, activity ability and participation in daily life. A score of 0 on the mRS Scale indicates no symptoms and a score of 5 indicates severe disability.	At 90±7 days after randomization
Secondary	The mRS score at 90±7 days after randomization	The modified Rankin Scale (mRS) decreasing to 0~1 score. mRS Mainly measures patients' independent living ability, including physical function, activity ability and participation in daily life. A score of 0 on the mRS Scale indicates no symptoms and a score of 5 indicates severe disability.	At 90±7 days after randomization
Secondary	Changes of NIHSS score between baseline and at 24 ± 2 hours, 7 ± 2 days and 28 + 3 days after randomization	NIHSS score after reperfusion therapy within 2 hours changing compared with baseline NIHSS. The NIHSS score ranges from 0 to 42. The higher the score, the more severe the nerve damage.	At 24 ± 2 hours, 7 ± 2 days and 28 + 3 days after randomization
Secondary	Proportion of patients with early progression of stroke at 24 ± 2 hours after randomization	Early progression of stroke was defined as: within 7 days after onset, compared to baseline, an increase of = 2 points in NIHSS; or an increase of = 1 point in limb hemiplegia; or an increase of = 1 point in consciousness disorder, excluding those caused by intracranial hemorrhage and other non-stroke causes such as cardiac insufficiency, liver insufficiency, renal insufficiency, etc.	At 24 ± 2 hours after randomization
Secondary	Proportion of patients with combined vascular events at 90 ± 7 days after randomization	Combined vascular events were defined as: symptomatic stroke, myocardial infarction and vascular death.	At 90 ± 7 days after randomization
