A prospective evaluation of edoxaban compared to warfarin in subjects undergoing cardioversion of atrial fibrillation: The EdoxabaN vs. warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation (ENSURE-AF) study

摘要

We designed a prospective, randomized, open-label, blinded end point evaluation parallel group Phase 3b clinical trial comparing edoxaban (a new oral factor Xa inhibitor) with enoxaparin/warfarin followed by warfarin alone in subjects undergoing planned electrical cardioversion of non-valvular atrial fibrillation. The primary efficacy end point is the composite end points of stroke, systemic embolic event, myocardial infarction, and cardiovascular (CV) mortality, from randomization until the end of follow-up (day 56 post cardioversion). The primary safety end point is the composite of major and clinically-relevant non-major bleeding, from the first administration of study drug to end of treatment (Day 28 post cardioversion) +3 days. The primary efficacy analysis will be conducted on the intention-to-treat population whereas the primary safety analysis, on the safety population.
