- In PEGASUS-TIMI 54, ticagrelor significantly reduced the risk of the composite of major adverse cardiovascular (CV) events by 15-16% in stable patients with a prior myocardial infarction (MI) 1-3 years earlier. We report the efficacy and safety in the subpopulation recommended for treatment in the European (EU) label, i.e. treatment with 60 mg b.i.d. initiated up to 2 years from the MI, or within 1 year after stopping previous adenosine diphosphate receptor inhibitor treatment.Of the 21 162 patients enrolled in PEGASUS-TIMI 54, 10 779 patients were included in the primary analysis for this study, randomized to ticagrelor 60 mg (n = 5388) or matching placebo (n = 5391). The cumulative proportions of patients with events at 36 months were calculated by the Kaplan-Meier (KM) method. The composite of CV death, MI, or stroke occurred less frequently in the ticagrelor group (7.9% KM rate vs. 9.6%), hazard ratio (HR) 0.80 [95% confidence interval (CI) 0.70-0.91; P = 0.001]. Ticagrelor also reduced the risk of all-cause mortality, HR 0.80 (0.67-0.96; P = 0.018). Thrombolysis in myocardial infarction major bleeding was more frequent in the ticagrelor group 2.5% vs. 1.1%; HR 2.36 (1.65-3.39; P < 0.001). The corresponding HR for fatal or intracranial bleeding was 1.17 (0.68-2.01; P = 0.58).In PEGASUS-TIMI 54, treatment with ticagrelor 60 mg as recommended in the EU label, was associated with a relative risk reduction of 20% in CV death, MI, or stroke. Thrombolysis in myocardial infarction major bleeding was increased, but fatal or intracranial bleeding was similar to placebo. There appears to be a favourable benefit-risk ratio for long-term ticagrelor 60 mg in this population.http://www.clinicaltrials.gov NCT01225562.

- OBJECTIVES: The study sought to evaluate the effect of dabigatran dual therapy versus warfarin triple therapy across categories of renal function in the RE-DUAL PCI (Randomized Evaluation of Dual Antithrombotic Therapy with Dabigatran versus Triple Therapy with Warfarin in Patients with Nonvalvular Atrial Fibrillation Undergoing Percutaneous Coronary Intervention) trial.BACKGROUND: The RE-DUAL PCI (NCT02164864) trial of patients with atrial fibrillation undergoing percutaneous coronary intervention reported that dabigatran dual therapy (110 or 150 mg twice daily, plus clopidogrel or ticagrelor) reduced the primary endpoint of major bleeding events (MBE) or clinically relevant nonmajor bleeding events (CRNMBE) compared with warfarin triple therapy, with noninferiority in overall thromboembolic events.METHODS: Risk of a first MBE or CRNMBE and the composite of death or thromboembolic event (DTE) or unplanned revascularization were evaluated in 2,725 patients according to baseline creatinine clearance (CrCl) categories: 30 to <50, 50 to <80, and >= 80 ml/min.RESULTS: Compared with warfarin, dabigatran 110 mg dual therapy reduced risk of MBE or CRNMBE across all categories of CrCl (p for interaction = 0.19). Dabigatran 150 mg dual therapy reduced risk of MBE or CRNMBE regardless of the CrCl category (p for interaction = 0.31). Risk of DTE or unplanned revascularization was similar to warfarin triple therapy for dabigatran 110 mg dual therapy across all CrCl categories. Dabigatran 150 mg dual therapy versus warfarin triple therapy had similar risk for DTE or unplanned revascularization in patients with CrCl 30 to <80 ml/min and lower risk at CrCl >= 80 ml/min (p for interaction = 0.02).CONCLUSIONS: In the RE-DUAL PCI trial, dabigatran dual therapy reduced bleeding events versus warfarin triple therapy irrespective of renal function, with overall similar risks of thromboembolic events but lower risks with dabigatran 150 mg in patients with normal CrCl.

- AIMS: To investigate the safety and efficacy of dabigatran dual therapy (110 or 150 mg twice daily, plus clopidogrel or ticagrelor) vs warfarin triple therapy in patients with atrial fibrillation undergoing PCI for ST elevation myocardial infarction (STEMI).METHODS AND RESULTS: In RE-DUAL PCI, 305 patients with STEMI were randomised to dabigatran 110 mg (n=113 versus 106 warfarin) or 150 mg (n=86 versus 84 warfarin). Primary endpoint was time to first major or clinically relevant non-major bleeding event (MBE/CRNMBE). The thrombotic endpoint was a composite of death, thromboembolic events, or unplanned revascularisation. In STEMI patients, dabigatran 110 mg (HR 0.39, 95% CI 0.20-0.74) and 150 mg (0.43, 0.21-0.89) dual therapy reduced the risk of MBE/CRNMBE versus warfarin triple therapy (p interaction vs all other patients = 0.31 and 0.16). Risk of thrombotic events, for dabigatran 110 mg (HR 1.61, 95% CI: 0.85-3.08) and 150 mg (0.56, 0.20-1.51) had p interactions of 0.20 and 0.33, respectively. For net clinical benefit, HRs were 0.74 (95% CI 0.46-1.17) and 0.49 (0.27-0.91) for dabigatran 110 and 150 mg (p interaction = 0.80 and 0.12).CONCLUSIONS: In patients after PCI for STEMI, dabigatran dual therapy had lower risks of bleeding events versus warfarin triple therapy with similar risks of thromboembolic events, supporting the use of dabigatran dual therapy even in patients with high thrombotic risk.
