This is a multicenter, prospective, non-randomized, post-marketing safety surveillance cohort study with rt-PA (Actilyse®) as the control. It is designed to evaluate the safety of intravenous thrombolysis with recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA, Mingfule®) compared with rt-PA (Actilyse®) in patients with acute ischemic stroke in the real-world setting.
This is a non-interventional observational study with no randomization. Treatment decisions are made by treating physicians based on routine clinical practice and the patient's condition. Patients are naturally allocated to the rhTNK-tPA group or the rt-PA group according to the actual thrombolytic drug they receive.

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.

This study is designed to evaluate the efficacy of IV rhTNK-tPA between 4.5 to 24 hours from symptom onset in patients presenting with a non-large vessel occlusion ischemic stroke.
