ObjectiveOptimal antithrombotic strategy for patients with concomitant coronary artery disease and atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) is still controversial, and the role of novel antithrombotic agents has nerve been tested. Therefore, the aim of this study is to evaluate and overall safety and efficacy profile of the combination of rivaroxaban and ticagrelor in this particular population.DesignThe RT-AF study is an open-label, randomized, active-controlled, multicenter clinical trial with up to 420 subjects enrolled in 5 centers. Eligible patients, who have a history or new onset paroxysmal, persistent, or permanent non-valvular AF, referred to the study centers with indications for PCI will be randomly assigned to receive triple therapy (including warfarin, clopidogrel and aspirin) or dual therapy (rivaroxaban and ticagrelor). All subjects will have clinical follow-up at discharge, at 30 days, 6 months and 12 months. The primary end point is major or clinically relevant non-major bleeding events at 12 months. The major secondary end point is the composite efficacy outcome of death, myocardial infarction, stent thrombosis and ischemic stroke.ConclusionThe study will be sufficiently powered to provide data primarily regarding the safety of dual therapy with rivaroxaban and ticagrelor over the traditional triple therapy in patients with AF undergoing PCI at 12 months. It will also provide important information regarding the efficacy of the two different antithrombotic regimens. (ClinicalTrials.gov identifier: NCT02334254).Copyright © 2015.
