Clinical Trial Summary

The trial is prospective, block randomized, open-label, blinded endpoint (PROBE) design. Patients with acute ischemic stroke, who are eligible for standard intravenous thrombolysis within 4.5 hours of stroke onset will be randomized 1:1:1 to 0.25mg/kg or 0.40mg/kg intravenous tenecteplase or 0.9 mg/kg alteplase before all participants undergo endovascular thrombectomy.

Description:

The study will be a multi-center, prospective, randomized, open- label, blinded endpoint (PROBE), controlled phase 2 trial (3 arm with 1:1:1 randomization) in ischemic stroke patients. Imagine is performed with CT or MRI acutely with imaging follow-up at 24-30 hours. The sample size is 225.

• Unable to complete neurological assessment and follow-up visits because of dementia or mental illness;
• Pregnant women, lactating women, or have positive pregnancy test;
• Allergy to tenecteplase or alteplase or their components;
• Participation in other clinical trials within 3 months prior to screening;
• Unsuitable to involve in this study or would result in increased risk, as judged by the investigators.
