Summary

Recent studies have shown that withdrawing aspirin and maintaining P2Y12 inhibitor monotherapy for up to 12 months post-PCI, after a brief period of DAPT, reduces bleeding without increasing ischemic harm. Such effects have shown to of particular benefit in patients with diabetes mellitus (DM). However, if an aspirin-free approach can be considered after this time frame is a matter of debate. The aim of this study is to assess the PD effects of ticagrelor 60 mg with and without aspirin therapy in CAD patients and to compare this with a standard DAPT regimen of aspirin plus clopidogrel.

Conditions

Interventions

DRUG

Ticagrelor monotherapy

Eligible patients will enter a 7-10 day run-in phase with aspirin 81 mg/ qd plus ticagrelor 90 mg bid after which they will discontinue aspirin and maintain ticagrelor 90 mg bid monotherapy for 10±3 days. After this period, patients will be randomized using a randomly generated computer sequence in a 1:1:1 fashion to either: a) ticagrelor 60 mg bid monotherapy; b) aspirin 81 mg qd plus ticagrelor 60 mg bid; c) aspirin 81 mg qd plus clopidogrel 75 mg qd. Randomized treatment will be maintained for 10±3 days.

DRUG

Ticagrelor plus aspirin

Eligible patients will enter a 7-10 day run-in phase with aspirin 81 mg/ qd plus ticagrelor 90 mg bid after which they will discontinue aspirin and maintain ticagrelor 90 mg bid monotherapy for 10±3 days. After this period, patients will be randomized using a randomly generated computer sequence in a 1:1:1 fashion to either: a) ticagrelor 60 mg bid monotherapy; b) aspirin 81 mg qd plus ticagrelor 60 mg bid; c) aspirin 81 mg qd plus clopidogrel 75 mg qd. Randomized treatment will be maintained for 10±3 days.

DRUG

Clopidogrel with aspirin

Eligible patients will enter a 7-10 day run-in phase with aspirin 81 mg/ qd plus ticagrelor 90 mg bid after which they will discontinue aspirin and maintain ticagrelor 90 mg bid monotherapy for 10±3 days. After this period, patients will be randomized using a randomly generated computer sequence in a 1:1:1 fashion to either: a) ticagrelor 60 mg bid monotherapy; b) aspirin 81 mg qd plus ticagrelor 60 mg bid; c) aspirin 81 mg qd plus clopidogrel 75 mg qd. Randomized treatment will be maintained for 10±3 days.
