Acute Stroke Clinical Trial

Official title: Low-dose Versus Standard-dose Ateplase in Acute Ischemic Stroke ; A 4 Months Prospective Randomized Control Pilot Follow by Single Arm Standard Dose Ateplase Study.

Status Completed

Clinical Trial Summary

Cohort A Randomized Control trial of Ateplase 0.6, 0.75 and 0.9 mg/kg in 78 patients Cohort B single arm 0.9 mg/kg Ateplase in 330 patients Combined Cohort A and B evaluate different of death, intra-cerebral hemorrhage, numberof patient with mRS 0-1 at discharge and 3 months follow up, and other important stroke outcomes

Clinical Trial Description

We conducted the prospective study to compare the low-dose and standard-dose rtPa and identify the important factors predicted stroke outcomes in acute stroke patient received intravenous rtPa. In Cohort A, During 2011-2012, 78 patients were randomly assigned to received intravenous rtPa 0.6 mg/kg , 0.75 mg/Kg, or 0.9 mg/Kg (1:1:1). After interim analysis during 2012-2017, in Cohort B, 330 patients were assigned to receive standard-dose rtPa 0.9 mg/kg. The good outcomes were defined as improvement of modified Rankin scale (mRS) by final score 0-1 or improvement > 4 points at discharge or 3 months follow up, absent of intracranial hemorrhage within 36 hours treatment, 90-day post-stroke survival , and short hospital length of stay. ;
