Background • Balancing ischemic and bleeding complications post PCI is an important dilemma for clinicians. 1 -3 • Addressing the clinical imperatives of lowering bleeding while preserving ischemic benefit requires therapeutic strategies that decouple thrombotic from hemorrhagic risk. • Reducing the duration of aspirin after PCI may allow for more prolonged use of potent P 2 Y 12 inhibitors while avoiding aspirin-related bleeding risk. 4 1.

Trial Hypothesis In patients undergoing PCI who are at high risk for ischemic or hemorrhagic complications and who have completed a 3 -month course of dual antiplatelet therapy with ticagrelor plus aspirin, continued treatment with ticagrelor monotherapy would be superior to ticagrelor plus aspirin with respect to clinically relevant bleeding and would not lead to ischemic harm.

Trial Objectives Primary Objective: To determine the impact of SAPT (ticagrelor monotherapy) versus DAPT

Trial Objectives Primary Objective: To determine the impact of SAPT (ticagrelor monotherapy) versus DAPT (ticagrelor plus aspirin) for 12 months in reducing clinically relevant bleeding (BARC 2, 3 or 5) among high-risk patients who have undergone successful PCI. Secondary Objective: To determine the impact of SAPT (ticagrelor monotherapy) versus DAPT (ticagrelor plus aspirin) for 12 months on major ischemic adverse events (all-cause death, non-fatal MI or stroke) among high-risk patients who have undergone successful PCI.

Methods TWILIGHT was a randomized, double-blinded, placebo-controlled trial conducted in 187 sites across 11

Methods TWILIGHT was a randomized, double-blinded, placebo-controlled trial conducted in 187 sites across 11 countries. From July 2015 - December 2017, patients undergoing successful PCI with at least 1 locally-approved DES whom the treating clinician intended to discharge on ticagrelor plus aspirin were eligible to participate. Trial inclusion required the presence of at least 1 additional clinical and angiographic feature associated with a high risk of ischemic or bleeding events.

Sample Size and Power Calculations Assuming a one-year rate of BARC 2, 3 or

Sample Size and Power Calculations Assuming a one-year rate of BARC 2, 3 or 5 bleeding of 4. 5% among patients receiving DAPT, a sample size of 8200 was chosen to detect a relative reduction of at least 28% with ticagrelor monotherapy and a type I error of 0. 05. Assuming a one-year rate of 8. 0% for the key secondary endpoint, a sample size of 8200 provided 80% power to exclude an absolute non-inferiority margin of 1. 6% with type I error 0. 025. An enrolled cohort of 9000 was chosen to accommodate an approximate 10% rate of randomization ineligibility.

Statistical Analysis The cumulative incidences of the primary and key secondary endpoints were expressed

Statistical Analysis The cumulative incidences of the primary and key secondary endpoints were expressed as Kaplan. Meier estimates by treatment group. Hazard ratios (HR) and 95% confidence intervals (CI) were generated using Cox proportional hazards models with treatment allocation as a single covariate. Treatment effects were also expressed as absolute risk differences using the one-year Kaplan-Meier estimates and Greenwood standard errors. Superiority testing using a log-rank p-value was performed for the primary endpoint. For the key secondary endpoint a one-sided non-inferiority test was performed using the upper limit of the 95% CI for the absolute risk difference. The primary endpoint was evaluated in the intention to treat (ITT) cohort while the key secondary endpoint was assessed in the per protocol cohort.

Limitations • These results may not be generalizable to § all patients undergoing PCI,

Limitations • These results may not be generalizable to § all patients undergoing PCI, given the requirement in our trial for both high-risk (clinical and angiographic) features, and § patients receiving background therapy with other P 2 Y 12 inhibitors. • Observed treatment effects do not apply to all enrolled participants but rather to those patients who were able to take 3 months of dual antiplatelet therapy without any major adverse events. • A lower-than expected incidence of the composite end point of death, MI, or stroke may have biased our results for this key secondary end point toward the null. • Lack of power to detect differences in the risk of important yet rare clinical events, such as stent thrombosis and stroke.

Conclusions In high-risk patients who underwent PCI and were treated with ticagrelor and aspirin

Conclusions In high-risk patients who underwent PCI and were treated with ticagrelor and aspirin for 3 months without any major adverse (bleeding or ischemic) events, an antiplatelet strategy of continuing ticagrelor monotherapy resulted in: • substantially less bleeding than ticagrelor plus aspirin • without increasing ischemic events over a period of 1 year
