Overview
Brief Summary
This is a prospective, multicenter, randomized, double-blind, placebo-controlled, phase IIb clinical trial of Androtriol injection for the treatment of acute ischemic stroke. The goal of this trial is to explore the efficacy and safety of different doses of Androtriol injection in patients with acute ischemic stroke (AIS) who received vascular recanalization treatment within 24 hours of symptom onset.
Participants will receive a low-dose Androtriol injection (100 mg BID), a high-dose Androtriol injection (300 mg BID), or a placebo intravenously within 24 hours of stroke onset. They will be treated twice daily (every 12 hours) for 7 days, with a total of 14 doses over the course of the study. Each infusion will last approximately 30±5 minutes.

Outcomes
Primary Outcomes
The proportion of participants with a modified Rankin Scale (mRS) score of 0-1 at 90 days after stroke onset
Time Frame: 90 days after stroke onset
The mRS denotes modified Rankin Scale, ranging from 0 (no neurologic deficit, no symptoms or completely recovered) to 6 (death).
Secondary Outcomes

- The proportion of participants with a modified Rankin Scale (mRS) score of 0-2 at 90 days after stroke onset(90 days after stroke onset)
- The change of the National Institutes of Health Stroke Scale (NIHSS) score from baseline at 14 days after stroke onset or at discharge(Baseline, 14 days or at discharge)
- The change of Barthel Index (BI) scores at 30 days and 90 days after stroke onset(Baseline, 30 days and 90 days after stroke onset)
- The change of EuroQol Five Dimensions Questionnaire (EQ-5D) scores at 30 days and 90 days after stroke onset(Baseline, 30 days and 90 days after stroke onset)
