Abstract:

Previous studies have found an association between clinical outcomes and CYP2C19 genetic polymorphisms in clopidogrel patients, without a placebo-controlled comparison. Using retrospective genotyping of two large placebo-controlled trials, we examined the differential effects of clopidogrel versus placebo on both ischemic and bleeding outcomes across genotypes. We found that examining the interaction between genotype and treatmentis essential to understanding the genetic effect. In addition, genotyping an uncommon gain-of-function polymorphism allowed us to identify a genotype with enhanced efficacy.
