Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
TWILIGHT study is a multicenter RCT comparing treatment with ticagrelor alone versus ticagrelor plus aspirin in high-risk patients after PCI. All patients will receive DAPT (ticagrelor plus aspirin) for the initial 3 months post-PCI and then be randomized to either Ticagrelor alone OR Ticagrelor plus Aspirin DAPT. To investigate the pharmacodynamic effects of the two treatments in this trial, a 'Platelet Sub-study' will be conducted only at the Mount Sinai Medical Center. The sub-study will recruit randomized patients from the TWILIGHT Trial at Mount Sinai and conduct specialized blood tests at randomization and one month thereafter. The aim of the Platelet Sub-study is to compare the antithrombotic effects of Ticagrelor alone versus Ticagrelor plus Aspirin using an ex vivo model of thrombosis (Badimon Chamber).
