Brief Summary

It is standard treatment to take anti-platelet medication after cardiac catheterization and stent placement to help prevent the formation of blood clots that may cause heart attack or stroke. The most...

Over a three-year period, a total of 7,200 patients undergoing percutaneous coronary intervention (PCI) in whom dual anti-platelet therapy is indicated for at least one year and meet the eligibility c...

Eligibility Criteria

Inclusion

  • Males or non-pregnant females between the ages of 20 and 74 years, inclusive
  • Not more than four days post-PCI (percutaneous coronary intervention) with placement of one or more drug eluting or bare metal stents
  • One or more stent(s) delivered with final TIMI 3 flow (thrombolysis in myocardial infarction grade 3) in the stented vessel(s)
  • Must have evidence of one of the following:
  • Three vessel disease;
  • Two vessel disease with one of the following: estimated creatinine clearance \<60, prior myocardial infarction, diabetes mellitus on treatment, peripheral artery disease, cerebrovascular disease, bifurcation stent, overlapping stents, or total stent deployment length \> 40 mm in length;
  • Single vessel disease with two of the following: estimated creatinine clearance \<60, prior myocardial infarction, diabetes mellitus on treatment, peripheral artery disease, cerebrovascular disease, bifurcating stenting, overlapping stents, or total stent deployment length \> 40 mm in length.
  • Patients with acute MI (myocardial infarction) preceding the PCI must have CK-MB (bound combination of creatine kinase M and creatine kinase B) value lower than the prior value, before randomization
  • Patients with peri-procedural MI, defined by CK-MB three times greater than upper reference limit (URL), must have CK-MB value lower than the prior value, before randomization. Peri-procedural MI will be screened per clinical suspicion.
  • Have an indication for one year of dual anti-platelet therapy with a P2Y12 inhibitor and aspirin
  • Agreement of the treating physician to prescribe anti-platelet therapy according to randomization and study dosing algorithm
  • Ability to understand and comply with planned study procedures
  • Provide written informed consent prior to study entry
  • Agrees to authorize the collection and release of his/her medical information for the duration of the trial or until the subject withdraws

Exclusion

  • History of a gastrointestinal bleed within three months or a major, life threatening bleeding event (e.g., sub-arachnoid or intracranial hemorrhage)
  • Active pathological bleeding (e.g. GI bleeding)
  • History of bleeding diathesis or coagulopathy
  • History of stroke or transient ischemic attack (TIA)
  • Non-cardiac surgery within the prior 3 months
  • Planned cardiac or non-cardiac surgery within the next 12 months
  • CYP2C19 genotype already known to subject or research team from prior genetic testing
  • Post-PCI CABG (coronary artery bypass graft) before randomization
  • Planned warfarin or dabigatran therapy any time during the study period
  • Known allergy to aspirin, clopidogrel or prasugrel
  • Platelet count \<100,000/mm3
  • Hematocrit \< 25%
  • Pregnancy
  • Concurrent enrollment in another trial that involves an investigational stent, antithrombotic or anti-platelet agent
  • Any condition that would, in the opinion of the site investigator, place them at an unacceptable risk or render them unable to meet the requirements of the protocol
  • Any subject, in the opinion of the investigator, not expected to tolerate or be adherent with one year of dual antiplatelet therapy
