Y-6 Sublingual Tablets for Patients With Acute Ischemic Stroke

Официальное название

Effects of Y-6 Sublingual Tablets for Patients With Acute Ischemic Stroke: a Randomised, Double-blind, Multicenter, Placebo-controlled Phase 3 Trial (FUTURE-2)

Обзор

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 will receive EVT. Moreover, we expect to evaluate the safety of using Y-6 sublingual tablet in such study population. 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. Dexborneol has anti-inflammatory effects and Cilostazol has antiplatelet effects and BBB protection; 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 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, 1 day, 7 days, 28 days and 90 days after randomization, and in case of any events.

Вмешательства

• Препарат Y-6
  each tablet of Y-6 contained 6 mg of dexborneol and 25 mg of cilostazol; Both groups took one tablet q12h for 28 days.
• Препарат Y-6 placebo
  each tablet of Y-6 placebo contained 0.06 mg of dexborneol and 0 mg of cilostazol. Both groups took one tablet q12h for 28 days.
