Brief Summary

Clopidogrel is an anti-platelet medication approved by the U.S. Federal Drug Administration (FDA) for use in patients who undergo Percutaneous Coronary Intervention (PCI) with coronary stent implantation. Anti-platelet medications work to prevent blood clots from forming. Some studies have suggested that patients who have a certain genetic liver enzyme abnormality (known as cytochrome P450 2C19 \[CYP2C19\] \*2 or \*3 allele) may have a reduced ability to activate clopidogrel, and therefore may have a lowered response to clopidogrel. It is thought that perhaps people who have a coronary stent procedure may have this genetic liver enzyme abnormality. There is a research genetic test available to determine whether or not someone has this genetic liver enzyme abnormality. Ticagrelor, is a newer anti-platelet drug that is not dependent on the CYP2C19 liver enzyme for its activation and hence in poor clopidogrel metabolizers, alternative drugs like Ticagrelor have been recommended for use as an anti-platelet agent after PCI. The purpose of this study is to determine if genetic testing can identify the best anti-platelet therapy, for patients who undergo a coronary stent placement and do not activate clopidogrel very well.

Outcome Measures

Primary Outcomes (2)

  • Occurrence of the a Major Adverse Cardiovascular Event in Subjects Identified as CPY2C19 LOF Carriers by TaqMan.

    Number of subjects who experienced major adverse cardiovascular event as defined as cardiovascular death, myocardial infarction, stroke, severe recurrent ischemia, and stent thrombosis in subjects identified as CPY2C19 LOF carriers by TaqMan.

    1 year after percutaneous coronary intervention (PCI)

  • Occurrence of the a Major Adverse Cardiovascular Event

    Number of subjects to experience a major adverse cardiovascular event as defined as cardiovascular death, myocardial infarction, stroke, severe recurrent ischemia, and stent thrombosis.

    Approximately 3 years after percutaneous coronary intervention (PCI)

Secondary Outcomes (2)

  • Thrombolysis in Myocardial Infarction Major or Minor Bleeding in Subjects Identified as CPY2C19 LOF Carriers by TaqMan.

    1 year after percutaneous coronary intervention (PCI)

  • Thrombolysis in Myocardial Infarction Major or Minor Bleeding

    Approximately 3 years after percutaneous coronary intervention (PCI)

Study Arms (2)

Genotype-Guided Therapy

EXPERIMENTAL

Subjects will be genotyped prospectively for CYP2C19\*2, \*3 and \*17 alleles and will receive treatment based on their genotype. In this group, patients who have the CYP2C19 reduced function allele \[i.e., \*2 allele (heterozygous or homozygous) or \*3 allele (heterozygous or homozygous)\] patients will receive ticagrelor 90 mg bid. The WT YP2C19 patients will receive clopidogrel 75 mg once daily.

Drug: ClopidogrelDrug: Ticagrelor

Conventional Therapy

ACTIVE COMPARATOR

Subjects will receive clopidogrel once daily after the index PCI and will be retrospectively genotyped for CYP2C19\*2, \*3 and \*17 alleles after completion of one year of treatment with clopidogrel.

Drug: Clopidogrel

Interventions

One 75 mg tablet per day by mouth for one year

Also known as: Plavix
Conventional TherapyGenotype-Guided Therapy

One 90 mg tablet twice per day by mouth for one year

Also known as: Brilinta
Genotype-Guided Therapy

  • Serum creatinine \>2.5 mg/dL within 7 days of index procedure
  • Platelet count \<80,000 or \>700,000 cells/mm3, or white blood cell count \<3,000 cells/mm3 if persistent (at least 2 abnormal values) within 7 days prior to index procedure.
  • History of intracranial hemorrhage
  • Known hypersensitivity to clopidogrel or ticagrelor or any of its components
  • Patient is participating in an investigational drug or device clinical trial that has not reached its primary endpoint
  • +14 more criteria
