Brief Summary

The CHESTNUT trial is a multicenter, open-label, blinded-endpoint, randomized, controlled, phase 3 trial. The primary objective of this study is to explore the efficacy and safety of the dose of 0.25 mg/kg tenecteplase (TNK) in Chinese acute ischemic stroke (AIS) patients without substantial infarction on non-contrast computed tomography (NCCT) in an extended time window.

Baseline NIHSS (National Institutes of Health Stroke Scale) score \>5. 5. Premorbid modified Rankin Scale (mRS) ≤1. 6. Imaging criteria: Automated infarct segmentation by NCCT post-processing model indicates infarct core volume \<50 mL with no visible hypodensity in \>1/3 of the MCA territory. 7. Informed consent signed by the patient or the patient's legally authorized representative. Exclusion Criteria: 1. Obvious hypodensity on NCCT deemed related with the current stroke event, with no expected benefit from thrombolysis as assessed by the investigators 2.
