The purpose of this study is to evaluate if Apixaban will decrease the complication of having another stroke for people who have atrial fibrillation if initiated earlier than standard of care.
This is an Open label, randomized, active control, parallel-group pilot trial to examine the effect of initiation of APIXABAN at days 0-3 (TIA), days 3-5 (small stroke) and days 7-9 (medium stroke) to decrease fatal and/or recurrent stroke/TIA in 120 subjects who have suffered a recent( 0 to 48 hours from symptoms) TIA, or small to medium ischemic stroke compared to standard of care warfarin treatment regimen. Subjects will be randomly assigned in a 1:1 ratio to one of two treatment arms (apixaban or warfarin). Subjects will be followed for a total of 180 days during from screening through monthly follow-up visits.
