简要总结
Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF).
Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.
详细描述
ASPIRE is a randomized, double-blinded, phase III clinical trial designed to test the efficacy and safety of anticoagulation, compared with aspirin, in patients with a recent ICH and non-valvular AF. Seven hundred patients will be enrolled over 3.5 years and followed for study outcomes for a minimum of 12 months and maximum of 36 months. The primary efficacy outcome is any stroke (hemorrhagic or ischemic) or death from any cause. The secondary efficacy outcome is the change in the modified Rankin Scale score. Recruitment will take place at sites coordinated through the NIH/NINDS StrokeNet.

排除标准
- •Index event is hemorrhagic transformation of a brain infarction or hemorrhage into a tumor
- •History of earlier ICH within 12 months preceding index event
- •Active infective endocarditis
- •Clear indication for anticoagulant drugs (e.g., requires anticoagulation for deep vein thrombosis or pulmonary embolism) or antiplatelet drugs (e.g., requires aspirin or clopidogrel for recent coronary stent).

- •Known allergy to aspirin or apixaban
- •Concomitant participation in a competing trial
- •Considered by the investigator to have a condition that precludes safe or active participation in the trial
- •Persistent, uncontrolled systolic blood pressure (≥180 mm Hg)
- •ICH caused by an arteriovenous malformation (AVM) that has not yet been secured
