NCT04090281

Brief Summary

The study aims to determine the feasibility and clinical utility of incorporating precision medicine approaches, incorporating both cytochrome P450 2C19 (CYP2C19) genotyping and platelet reactivity phenotyping, with standard of care for patients with acute coronary syndromes (ACS), post PCI.

Study Arms (1)

Precision medicine implementation

OTHER

Patients will receive a precision medicine approach, incorporating both CYP2C19 genotyping and platelet reactivity phenotyping, to guide dual antiplatelet therapy selection for patients with ACS, post PCI and followed over a 12 month period.

Genetic: CYP2C19 genotyping

Interventions

Upon hospital discharge, patients will undergo CYP2C19 genotyping to guide initial P2Y12 inhibitor selection. At 14 days, post discharge, patients will undergo on treatment platelet reactivity phenotyping to further guide deescalation of P2Y12 inhibitor therapy

Also known as: platelet reactivity phenotyping
Precision medicine implementation

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with troponin positive ACS
  • Patients scheduled for left heart catheterization and undergoing PCI
  • Age 18-80 years at time of enrollment
  • Currently receiving or anticipated to receive DAPT, with P2Y12 inhibitor
  • Ability to follow-up for a clinic visit with LAC+USC outpatient cardiology
  • Written informed consent

You may not qualify if:

  • Subjects with known contraindications to clopidogrel treatment, which are hypersensitivity to the drug substance or any component of the product and active pathological bleeding such as peptic ulcer or intracranial hemorrhage
  • Subjects with known contraindications to prasugrel treatment, which are hypersensitivity to the drug substance or any component of the product, active pathological bleeding such as peptic ulcer or intracranial hemorrhage, and a history of prior transient ischemic attack (TIA) or stroke
  • Subjects with a history of a complicated or prolonged cardiogenic shock in the last two weeks prior to enrolling in this study. A complicated or prolonged cardiogenic shock is defined by a cardiogenic shock that required mechanical ventilation or the cardiovascular support with positive inotropic drugs (i. v. catecholamines) for ≥7 days.
  • Subjects requiring concomitant treatment with an anticoagulant agent (Vitamin-K antagonists or novel oral anticoagulants such as rivaroxaban, dabigatran or apixaban)
  • Indication for major surgery (per decision of the treating physician) for the planned duration of the study
  • Subject with history of liver transplant or plan to undergo liver transplant during the next 12 months
  • Evidence of significant active neuropsychiatric disease, in the investigator's opinion.
