NCT00995514

Brief Summary

The primary objective of this trial is to demonstrate the non-inferiority of clopidogrel compared to prasugrel over 6 months in cardiovascular disease patients when the clopidogrel cohort is limited to the estimated 70% of the population that are CYP2C19 extensive metabolizers. This protocol will examine the comparative effectiveness of these two strategies.

Outcome Measures

Primary Outcomes (1)

  • Non-inferiority of clopidogrel therapy in CYP2C19 extensive metabolizers with cardiovascular disease

    To assess the non-inferiority of clopidogrel therapy in patients with cardiovascular disease who are CYP2C19 extensive metabolizers (identified by genetic testing) compared to prasugrel therapy (non-genotyped) on the composite primary end point of cardiovascular death, hospitalization for acute coronary syndrome (nonfatal MI or unstable angina), nonfatal stroke or coronary revascularization

    6 months

Secondary Outcomes (6)

  • Incidence between the two study groups of all individual components of the primary end point.

    6 and 12 months

  • Total health care resource utilization and cost-effectiveness

    6 and 12 months

  • Health-related quality of life and activity/work productivity

    6 and 12 months

  • Incidence of hospitalization for site- and cause-specific bleeding

    6 and 12 months

  • Incidence of new or recurrent cancer

    6 and 12 months

  • +1 more secondary outcomes

Study Arms (2)

Clopidogrel

Patients receiving clopidogrel 75 mg/day as prescribed by their physician, and are extensive metabolizers by CYP2C19 genotype

Prasugrel

Patients receiving prasugrel 5 or 10 mg/day as prescribed by their physician
