Based on current scientific evidence, acute coronary syndrome subjects should be treated with dual antiplatelet therapy, which consists of the association of acetylsalicylic acid with an oral antagonist of platelet P2Y12 receptor. Clinical trials have shown that dual antiplatelet therapy reduces ischemic events, despite of increasing the risk of bleeding complications. Because dual antiplatelet therapy has a positive net effect, such an approach is currently recommended by international guidelines and recognized as the therapy of choice for acute coronary syndrome subjects. It is known that the acetylsalicylic acid dose is directly proportional to the bleeding risk. However, so far, all new antiplatelet drugs have been tested and used in association with acetylsalicylic acid for a varying period of time. This study is carried out in such context and intends to evaluate the clinical performance of new inhibitors of platelet P2Y12 receptor given solely, as monotherapy, to acute coronary syndrome patients, to test the hypothesis that an antithrombotic monotherapy with such agents (i.e., acetylsalicylic acid withdrawal) sustains efficacy by preventing ischemic complications while reducing the bleeding potential of this drug dosage regimens. It is a Phase-3, randomized, multicenter, parallel-group study with blind evaluation of endpoints and intention-to-treat analysis. Subjects with acute coronary syndrome treated with a successful percutaneous coronary intervention will be enrolled. The general purpose of the study is to test the non-inferiority hypothesis for ischemic events and the superiority hypothesis for bleeding events resulting from platelet P2Y12 receptor inhibitors given as monotherapy in comparison with conventional dual antiplatelet therapy in the context of the Unified Health System in Brazil.
