ABSTRACT


OBJECTIVES - The aim of this study was to test the hypothesis that 6-month dual antiplatelet therapy (DAPT) is noninferior to 24-month DAPT in aspirin-sensitive patients.


BACKGROUND - The ITALIC (Is There a Life for DES After Discontinuation of Clopidogrel) trial showed that rates of bleeding and thrombotic events at 1 year were much the same with 6 versus 12 months of DAPT after percutaneous coronary intervention with second-generation drug-eluting stents. In this report, 2-year follow-up is presented.


METHODS - In a multicenter randomized study, patients with confirmed nonresistance to aspirin undergoing drug-eluting stent implantation were allocated to 6 or 24 months of DAPT. The primary endpoint was a composite of death, myocardial infarction, urgent target vessel revascularization, stroke, and major bleeding at 12 months post-percutaneous coronary intervention. The secondary endpoints comprised the same composite endpoint at 24 months and each individual component.


RESULTS Overall, 2,031 patients from 70 centers were screened; 926 were randomized to 6-month and 924 to 24-month DAPT. Noninferiority was demonstrated for 6- versus 12-month DAPT, with an absolute risk difference of 0.11% (95% confidence interval: -1.04% to 1.26%; p = 0.0002). At 2 years, the composite endpoint was unchanged, at 3.5% for 6 months and 3.7% for 24 months (p = 0.79), and rates of myocardial infarction (1.3% vs. 1.0%; p = 0.51), stroke (0.6% vs. 0.8%; p = 0.77), and target vessel revascularization (1.0% vs. 0.3%; p = 0.09) were likewise similar. There was a trend toward higher mortality with longer DAPT (2.2% vs. 1.2%; p = 0.11). Four patients (0.4%) in the 24-month group and none in the 6-month group had major bleeding.


CONCLUSIONS - Two-year outcomes in the ITALIC trial confirmed the 1-year results and showed that patients receiving 6-month DAPT after percutaneous coronary intervention with second-generation drug-eluting stent have similar outcomes to those receiving 24-month DAPT.
