Brief Summary:
Randomized controlled study to examine physician use of pharmacogenetic information in patients receiving antiplatelet medication after percutaneous coronary intervention (PCI).

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Genetic: CYP2C19 genotyping Phase 4

Detailed Description:
The study will randomize patients who have completed PCI and who are prescribed dual antiplatelet therapy to a genotype guided arm, in which CYP2C19 pharmacogenetic testing will be performed and a standard therapy arm without genetic testing. The study will examine the impact of pharmacogenetic testing on physician medication choice and clinical outcomes.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 270 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: IU Health Krannert Personalized Medicine Study - Influencing Prescriber Behavior for the Use of Clopidogrel
Study Start Date : November 2016
Estimated Primary Completion Date : November 2018
Estimated Study Completion Date : November 2018

Arm Intervention/treatment
Active Comparator: Pharmacogenetic Testing Arm
Genotyping for CYP2C19 variants is performed. The test results are integrated into the electronic health record and alerts are displayed to the prescriber. The ultimate decision regarding antiplatelet therapy is left to the prescriber
Genetic: CYP2C19 genotyping
No Intervention: Control Arm
No genotyping information is performed as part of clinical care. Standard therapy is followed. Genotyping will be performed at conclusion of study in control arm, and genotyping results will not be incorporated into electronic health record.



Primary Outcome Measures :
  1. Change in prescription of antiplatelet therapy [ Time Frame: one year ]
    Number of individuals whose initial P2Y12 inhibitor therapy was changed to another P2Y12 inhibitor during time of follow up


Secondary Outcome Measures :
  1. Death, Myocardial Infarction, Stroke [ Time Frame: one year ]
    Combined incidence of either death, myocardial infarction or stroke during follow up

  2. Stent Thrombosis [ Time Frame: one year ]
    Combined incidence of stent thrombosis according to Academic Research Consortium definitions during follow up

  3. Urgent target vessel revascularization [ Time Frame: one year ]
    Incidence of urgent target revascularization

  4. Major and Minor Bleeding [ Time Frame: one year ]
    Incidence of Major or Minor Bleeding according to GUSTO criteria during follow up
