Brief Summary:
To compare the efficacy and safety of clopidogrel monotherapy versus aspirin plus P2Y12 antagonist following 3-month of DAPT in patients undergoing PCI with DES.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Drug: P2Y12 antagonist monotherapy Drug: aspirin plus P2Y12 antagonist Not Applicable

Detailed Description:
This trial is a prospective, randomized, multi-center, open label, noninferiority trial. Patients undergoing PCI with DES will be eligible. After successful PCI with DES, all eligible patients will be randomized either to clopidogrel monotherapy or to aspirin plus P2Y12 antagonist following 3-month of DAPT.
