What this Trial Is About

This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study designed to evaluate the efficacy of recombinant human tissue-type plasminogen activator variant (rhTNK-tPA) (0.25 mg/kg, maximum dose 25 mg) compared with placebo in patients with acute large vessel occlusive stroke who present within 4.5 to 24 hours of symptom onset. The study plans to enroll patients with acute large vessel occlusive stroke who present within 4.5 to 24 hours of symptom onset (including wake-up strokes and strokes without witnesses). A centralized 1:1 randomization will be adopted, and eligible participants will be randomly assigned to two groups: the experimental group will receive rhTNK-tPA at a dose of 0.25 mg/kg, while the placebo group will receive rhTNK-tPA placebo.
