|Condition or disease||Intervention/treatment||Phase|
|Ischemic Stroke||Drug: clopidogrel Drug: Aspirin||Early Phase 1|
The ATAMIS study is a multicentre, prospective, randomised, open-label, controlled trial with a target enrollment of 3,000 patients from 60 centres of the Northeast China. Eligible patients are as follows: (1) definite acute ischemic stroke; (2) neurological deficit: 4 ≤ NIHSS ≤ 10; (3) time from onset to drug treatment: within 48 hours.
Patients in the clopidogrel-aspirin group will receive a 300mg loading dose of clopidogrel, followed by clopidogrel 75 mg/d and aspirin 75 mg/d from day 2 to day 14, and followed by clopidogrel 75 mg/d or aspirin 100 mg/d from day 15 to day 90.
Patients in the aspirin-alone group will receive 100-300 mg aspirin from day 1 to day 14, followed by aspirin 100 mg/d from day 15 to day 90.
The primary efficacy end point is early neurological deterioration assessed as a change of NIHSS: no change of NIHSS within 14 days.
