Clinical Trial Summary

The primary purpose of this trial is to compare the efficacy of different doses of investigator product and comparator product in patients with acute ischemic stroke in 4.5 Hours after stroke onset, and provide a basis of drug administration for phase Ⅲ clinical trial.

The secondary purpose of this trial is to compare the safety of different dose of investigational product and comparator product in patients with acute ischemic stroke in 4.5 hours afterstroke onset .


Clinical Trial Description

This study is a multicenter, prospective randomised, open blinded endpoint study.

Patients with acute ischemic stroke need to undergo CT or MRI to exclude intracranial hemorrhage and perform NIHSS score before enrollment. Subjects who have passed the screening criteria according to the inclusion and exclusion criteria will be randomly assigned to low-dose test drugs, high-dose test drugs or reference drugs for thrombolytic therapy at a ratio of 1:1:1. The random stratification factor is the thrombolysis time window ("≤3h" vs "3~4.5h").

The start of administration of the study drug is recorded as 0h, CT or MRI and NIHSS score, laboratory test, and electrocardiogram were performed at 24 hours; NIHSS score was performed at 72 hours; NIHSS score,laboratory test and electrocardiogram were performed on the14th day(the start of administration is recorded as Day 1 ,then the 14th day after administration should be recorded as Day 15 ); mRS score and Barthel index score were performed on the 30th day (Day 31); mRS score and Barthel index score were performed on the 90th day (Day 91). ;
