Genome-wide and candidate gene approaches of clopidogrel efficacy using pharmacodynamic and clinical endpoints - Rationale and design of the International Clopidogrel Pharmacogenomics Consortium (ICPC)

摘要

RationaleThe P2Y12 receptor inhibitor clopidogrel is widely used in patients with acute coronary syndrome, percutaneous coronary intervention or ischemic stroke. Platelet inhibition by clopidogrel shows wide inter-patient variability and high on-treatment platelet reactivity is a risk factor for atherothrombotic events, particularly in high-risk populations. CYP2C19 polymorphism plays an important role in this variability, but heritability estimates suggest that additional genetic variants remain unidentified. The aim of the International Clopidogrel Pharmacogenomics Consortium (ICPC) is to identify genetic determinants of clopidogrel pharmacodynamics and clinical response.
