Summary

The purpose of this study is to evaluate the efficacy and safety of intravenous tenecteplase (0.25 mg/kg) compared with standard therapy in patients with acute ischemic stroke presenting with mild symptoms-defined as a National Institutes of Health Stroke Scale (NIHSS) score ≤5 accompanied by persistent unilateral limb weakness or speech impairment within 4.5 hours of onset.

Detailed description

This study is a multicenter, prospective, randomized, double-blind, double-dummy controlled (2 arms with 1:1 randomization) trial. Participants with acute minor ischemic stroke (baseline NIHSS≤5) within 4.5 hours of symptoms onset (symptom onset is defined by the "last seen normal" principle for wake-up stroke) will be enrolled. Eligible patients must have neurological deficits involving at least language or motor function. Participants will be randomized into 2 groups: Intervention group (rhTNK-tPA): 0.25mg/kg, the maximum dose does not exceed 25mg, plus placebo oral aspirin and clopidogrel. Aspirin 100mg and clopidogrel 300mg will be given within 6 ± 2 hours after thrombolytic therapy. Control group: Dual antiplatelet therapy with aspirin 100mg and clopidogrel 300mg, plus placebo intravenous rhTNK-tPA. Placebo oral aspirin and clopidogrel will be given within 6 ± 2 hours following the placebo thrombolytic therapy.The primary endpoint is an excellent functional outcome (a modified Rankin Scale score of 0-1) at 90-day.

Interventions

Type	Name	Description
DRUG	rhTNK-tPA	rhTNK-tPA 0.25mg/kg, the maximum dose does not exceed 25mg: 1 vial is dissolved in 3ml of sterile water for injection to prepare a medicinal solution with a concentration of 5.33mg/ml. Calculate the total amount of the drug according to the weight of participant, and the maximum dose shall not exceed 25 mg. It is administered as a single bolus intravenous injection, and the injection is completed within 5-10 seconds. Additionally, placebo oral aspirin and clopidogrel are given. Aspirin 100 mg and clopidogrel 300 mg are administered within 6 ± 2 hours following thrombolytic therapy.
DRUG	Control group (Aspirin combined with clopidogrel)	Dual antiplatelets with aspirin 100mg and clopidogrel 300mg, plus placebo intravenous rhTNK-tPA. Placebo oral aspirin and clopidogrel are administered within 6 ± 2 hours following intravenous placebo.
