Brief Summary

Rationale: the use of antiplatelet drugs (i.e. clopidogrel, ticagrelor or prasugrel) is crucial in the treatment of patients undergoing percutaneous coronary intervention (PCI) with stent implantation to prevent atherothrombotic events. Ticagrelor and prasugrel are more effective in preventing atherothrombotic events, but with a higher risk of bleeding complications, compared to clopidogrel. Clopidogrel is converted into its active metabolite by CYP2C19. Carriers of the non functional CYP2C19\*2 and \*3 alleles have an impaired CYP2C19 capacity, making clopidogrel less effective. For these subjects ticagrelor or prasugrel is an alternative. Objective: to assess the efficacy, safety and cost-effectiveness of the CYP2C19 genotype guided antiplatelet treatment strategy, using clopidogrel in non-carriers of a CYP2C19\*2 or \*3 allele and ticagrelor or prasugrel in carriers of a CYP2C19\*2 or \*3 allele in STEMI patients. Intervention: the intervention group will be genotyped for CYP2C19\*2 and \*3 allele variants within 48 hours after primary PCI. Carriers will receive either ticagrelor (90 mg twice daily) or prasugrel (10 mg once daily or 5 mg once daily if the patient is older than age 75 or has a body weight less than 60 kg), according to local standards. Non-carriers will be treated with clopidogrel (75 mg once daily). The control group receives either ticagrelor or prasugrel, according to local standards at the same dosage as the CYP2C19\*2 or \*3 carriers in the intervention group. The antiplatelet drug will be continued for one year after PCI. The follow-up duration will be one year using follow-up questionnaires.

Outcome Measures

Primary Outcomes (3)

  • Net clinical benefit

    The primary endpoint is the number of patients who either died, developed a recurrent myocardial infarction (MI), developed definite stent thrombosis, stroke or PLATO major bleeding at 1 year after PCI.

    1 year

  • Safety endpoint

    The primary safety endpoint is the number of patients with PLATO major or minor bleeding at 1 year after PCI.

    1 year

  • Pharmacoeconomics endpoint

    The primary endpoints in terms of pharmacoeconomics are quality of life, direct medical costs e.g. costs for blood transfusions, drugs, hospitalization and non-medical costs e.g. costs incurred due to sickness absence.

    1 year

Secondary Outcomes (4)

  • Net clinical benefit at 30 days

    30 days

  • Secondary efficacy and safety endpoint

    30 days and 1 year

  • Secondary safety endpoint

    30 days and 1 year

  • Drug endpoint

    30 days and 1 year

Study Arms (2)

Control group

NO INTERVENTION

CYP2C19 genotyping will be performed after end of study. Patients will be treated with prasugrel or ticagrelor, according to local protocol.

Intervention group

ACTIVE COMPARATOR

CYP2C19 genotyping will be performed \<48h after PCI and antiplatelet treatment will be chosen based on genotyping results.

Genetic: CYP2C19 genotyping

Interventions

CYP2C19 genotyping will be performed in the intervention group. In patients with \*1/\*1 genotype (Extensive Metabolizer) clopidogrel will be prescribed. All patients who are carrier of a loss-to-function (\*2 or \*3) gene allel and all patients randomized to the control group will be prescribed prasugrel or ticagrelor, according to local protocol.
