  Purpose

Nondisabling cerebrovascular events represent the largest group of cerebrovascular disease with a high risk of recurrent stroke. A recent trial indicated that clopidogrel and aspirin treatment reduced the risk of recurrent stroke and was not associated with increased hemorrhage events, compared with aspirin monotherapy. Apixaban, a new oral anticoagulant, is proved to be as effective as traditional anticoagulants with less risk of bleeding events.

To estimate whether apixaban is beneficial for acute TIA or minor stroke, a randomized, double-blind, multicenter, controlled clinical trial has been designed. The investigators will assess the hypothesis that a 21-days apixaban regimen is superior to clopidogrel and aspirin dual-therapy for the treatment of high-risk patients with acute nondisabling cerebrovascular event.

Detailed Description:

The ADANCE study is a randomized, double-blind clinical trial with a target enrollment of 3,000 Chinese patients. Two subtypes of patients will be enrolled: I, acute disabling ischemic stroke (<24 hours of symptoms onset); II, acute TIA (<24 hours of symptoms onset).

Patients will be randomized into 3 groups:

Ⅰ Receiving a 75 mg dose of clopidogrel and 75mg dose of aspirin from day 1 to day 21, with placebo apixaban twice daily.

Ⅱ Receiving a 2.5-mg twice daily of apixaban, with placebo clopidogrel and placebo aspirin from day 1 to day 21.

Ⅲ Receiving a 5-mg twice daily of apixaban, with placebo clopidogrel and placebo aspirin from day 1 to day 21.

From day 22 to 3 months, all patients will receive 75-mg dose of clopidogrel long-term antiplatelet therapy.

The primary efficacy end point is percentage of patients with new stroke (ischemic or hemorrhage) at 90 days.

Criteria

Inclusion Criteria:
