Study Details

Study Description

Brief Summary

The purpose of this study is to compare the use of ticagrelor alone versus ticagrelor and aspirin together. Both ticagrelor and aspirin stop platelets from sticking together and forming a blood clot that could block blood flow to the heart. This study will look to determine the effectiveness and safety of ticagrelor alone, compared to ticagrelor plus aspirin in reducing clinically relevant bleeding and in reducing ischemic adverse events among high-risk patients who have had a percutaneous intervention with at least one drug-eluting stent. A patient is considered high-risk if they meet certain clinical and/or anatomic criteria.

Up to 9000 subjects will be enrolled at the time of their index PCI. Subjects meeting randomization eligibility criteria at 3 months post enrollment will be randomized to either ticagrelor plus aspirin or ticagrelor plus placebo for an additional 12 months. Follow-up clinic visits will be performed at 3 months, 9 months and 15 months post enrollment.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

This is a multicenter, prospective, blinded dual-arm study. Up to 9000 high-risk patients who have undergone successful PCI with at least one locally approved drug eluting stent discharged on DAPT with aspirin and ticagrelor of at least 3 months intended duration from centers still to be determined in the U.S., Canada, Europe and Asia. The primary objective of this study is to determine the impact of antiplatelet monotherapy with ticagrelor alone versus DAPT with ticagrelor plus aspirin for 12 months in reducing clinically relevant bleeding (efficacy) among high-risk patients undergoing PCI who have completed a 3-month course of aspirin plus ticagrelor. The secondary objective of this study is to determine the impact of antiplatelet monotherapy with ticagrelor alone versus DAPT with ticagrelor plus aspirin for 12 months in reducing major ischemic adverse events (safety) among high-risk patients undergoing PCI who have completed a 3-month course of aspirin plus ticagrelor.

Exploratory objectives include assessing the comparative safety and efficacy of the different DAPT regimens for individual components of the primary efficacy and secondary safety objectives.

The primary analysis for TWILIGHT will be performed independently by the London School of Hygiene and Tropical Medicine

    Limitations include lack of power to detect differences in the risk of important yet rare clinical events, e.g stent thrombosis and stroke; and trial may not be generalizable to all patients undergoing PCI due to high risk criteria.
