Antiplatelet Therapy in Acute Mild-Moderate Ischemic Stroke — ATAMIS  

Ischemic Stroke Clinical Trial

Official title:
Antiplatelet Therapy in Acute Mild-Moderate Ischemic Stroke (ATAMIS): a Parallel Randomized, Open-label, Multicenter, Prospective Study

Clinical Trial Summary

The risk of early recurrence or progression of acute ischemic stroke is very high, even in patients treated with aspirin. The Chance study show that clopidogrel plus aspirin treatment reduced the risk of recurrent stroke in patients with transient ischemic attack (TIA) or minor ischemic stroke (NIHSS ≤ 3) within 24 hour onset and was not associated with increased hemorrhage events, compared with aspirin monotherapy. However, it is not known whether the dual antiplatelet treatment could reduce the risk of early recurrence or progression in patients with acute mild to moderate ischemic stroke (4 ≤ NIHSS ≤ 10). The investigators hypothesise that clopidogrel-aspirin treatment will be superior to aspirin monotherapy in this group of patients.

Clinical Trial Description

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. ;
