Clinical Trial Summary

The trial is a multicenter, prospective, open-label, blinded-endpoint randomized controlled design. Participants with acute minor ischemic stroke (baseline NIHSS≤5) accompanied with measurable neurological deficit will be randomized 1:1 to 0.25mg/kg intravenous tenecteplase or standard medical treatment.


Description:

The study will be a multicenter, prospective, open-label, blinded-endpoint randomized controlled trial (2 arms with 1:1 randomization). 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) accompanied with measurable neurological deficit will be enrolled. The measurable neurological deficit is defined as impairment of 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. Control group (standard medical care): Single/dual antiplatelet therapy (aspirin, clopidogrel, ticagrelor, etc.) according to the guideline. The primary endpoint is excellent functional outcome (Modified Rankin Scale score, mRS 0-1) at 90-day.

Intervention

Drug:
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.
Single/dual antiplatelet therapy
Single/dual antiplatelet therapy (aspirin, clopidogrel, ticagrelor, etc.) according to the guideline.
