Clopidogrel in High-risk Patients With Acute Non-disabling Cerebrovascular Events
NCT00979589 · Status: COMPLETED · Phase: PHASE3 · Type: INTERVENTIONAL · Enrollment: 5100
Last updated 2020-07-15
Summary
The purpose of this study is to assess the effects of a 3-month regimen of clopidogrel initiated with a loading dose (LD) of 300 mg followed by 75 mg/day during the first 21days versus a 3-month regimen of ASA 75 mg/day alone on reducing the 3-month risk of any stroke (both ischemic and hemorrhagic, primary outcome) when initiated within 24 hours of symptom onset in high-risk patients with TIA or minor stroke.
Conditions

- Transient Ischemic Attack
Interventions
- DRUG
-
Clopidogrel
The first group will receive a 300mg loading dose (LD) of clopidogrel on the day of randomization, followed by 75 mg clopidogrel/day from Day 2 to 3 months. ASA will be given in a total dose ranging between 75 mg and 300 mg (open label) on the first day, followed by blinded 75 mg once /day from Day 2 to Day 21st. Between Day 21st and 3-month visits, ASA 75 mg will be replaced by a placebo of ASA 75 mg.
- DRUG
-
Placebo of clopidogrel and Asprin
The second group will receive open label ASA in a total dose ranging between 75 mg and 300 mg on the first day, followed by blinded 75 mg once /day from Day 2 to 3 months. A placebo for clopidogrel will be given from the day of randomization until the 3-month visit.
