Brief Summary

Two strategies have both proven to be effective in reducing bleeding complications while preserving efficacy compared with maintaining long-term DAPT with aspirin and a potent P2Y12 inhibitor: a) DAPT de-escalation (i.e., switching from prasugrel or ticagrelor to clopidogrel while maintaining aspirin) and b) potent P2Y12 inhibitor monotherapy (i.e., maintaining prasugrel or ticagrelor and dropping aspirin). These strategies have been tested in a number of trials and have led to changes in practice guidelines to consider either one of these strategies as bleeding reduction approaches among ACS patients undergoing PCI. However, comparative assessments between DAPT de-escalation and potent P2Y12 inhibitor monotherapy are lacking.

Outcome Measures

Primary Outcomes (1)

  • Thrombus formation defined as AUC measured by T-TAS

    Comparison of the area under the curve (AUC) determined by Total Thrombus formation Analysis System (T-TAS) between potent P2Y12 monotherapy strategy and de-escalation strategy (trough effect).

    30 days

Study Arms (2)

DAPT de-escalation

ACTIVE COMPARATOR

Aspirin 81-mg od and clopidogrel 75-mg qd.

Drug: aspirin plus clopidogrel

Potent P2Y12 monotherapy

EXPERIMENTAL

Potent P2Y12 inhibitor with prasugrel 10 mg od or ticagrelor 90 mg BID.

Drug: prasugrel or ticagrelor

Interventions

After at least 30 days of DAPT \[with aspirin 81-mg od and a potent P2Y12 inhibitor (prasugrel 10 mg od or ticagrelor 90-mg BID)\] in chronic coronary syndrome or after at least 90 days of DAPT in acute coronary syndromes; patients will continue aspirin and switch to clopidogrel 75-mg.

DAPT de-escalation

After at least 30 days of DAPT \[with aspirin 81-mg od and a potent P2Y12 inhibitor (prasugrel 10 mg od or ticagrelor 90-mg BID)\] in chronic coronary syndrome or after at least 90 days of DAPT in acute coronary syndromes; patients will drop aspirin and continue prasugrel or ticagrelor.

Potent P2Y12 monotherapy

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients who presented with chronic coronary syndrome, underwent PCI and have been on maintenance treatment with DAPT, composed of low-dose aspirin (81mg od) and prasugrel (10 mg od) or ticagrelor (90 mg bid) for at least 30 days. Or patients that presented with an Acute coronary syndrome (ACS) event and underwent PCI and have been on maintenance treatment with DAPT, composed of low-dose aspirin (81mg od) and prasugrel (10mg od) or ticagrelor (90mg bid) for 3 months or greater.
  • Age ≥18 years old
  • Provide written informed consent

You may not qualify if:

  • Prior history of stent thrombosis
  • On treatment with any oral anticoagulant (vitamin K antagonists, dabigatran, rivaroxaban, apixaban, edoxaban) or chronic low-molecular-weight heparin (at venous thrombosis treatment, not for prophylaxis)
  • Renal failure requiring dialysis
  • Patients with known bleeding diathesis or coagulation disorders
  • Known severe hepatic impairment
  • Hemodynamic instability
  • Hypersensitivity to clopidogrel
  • Pregnant and breastfeeding women \[women of childbearing age must use reliable birth control (i.e., oral contraceptives) while participating in the study\]
