E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether the CYP2C19 genotype guided antiplatelet treatment strategy is not inferior to a treatment strategy with the newer antiplatelet drugs i.e. ticagrelor and prasugrel (control group) in terms of the composite of death, recurrent MI, definite stent thrombosis, stroke and PLATO major bleeding at 1 year, in patients undergoing primary PCI for STEMI. If non-inferiority is proven, analysis will be performed for superiority.
To determine whether the genotype guided treatment strategy is superior to a treatment of the control group in terms of a composite endpoint of PLATO major and minor bleeding.
To assess the quality of life of patients and health-care resource use in both treatment groups to calculate Quality Adjusted Life Years (QALY’s) and net costs per life-year and QALY.
|
|
E.2.2 | Secondary objectives of the trial |
To compare the safety and efficacy of the genotype guided treatment strategy versus the treatment of the control group in terms of clinical and safety outcome parameters taken separately or combinations of parameters.
To compare the genotype guided treatment strategy (subdivided into patients included before protocol version 05, 16-02-2012 and patients included starting with protocol version 05, 16-02-2012) to a treatment strategy with either clopidogrel in all patients or a treatment strategy with the newer antiplatelet drugs in terms of the composite of death, recurrent MI, definite stent thrombosis, stroke and PLATO major and minor bleeding.
To compare the efficacy and safety of CYP2C19 genotype guided antiplatelet treatment strategy to the treatment strategy with the newer antiplatelet drugs i.e. ticagrelor and prasugrel in subgroups.
To compare the number of patients in whom the antiplatelet drug is prematurely discontinued or switched in both treatment groups.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy 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.
The primary safety endpoint contains the number of patients with PLATO major or minor bleeding at 1 year after PCI.
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.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
At one year following PCI. |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints are the number of patients who either died, died from cardiovascular death, from cerebrovascular death, developed recurrent MI, definite stent thrombosis, probable stent thrombosis, possible stent thrombosis, underwent urgent target vessel revascularisation (TVR), hospitalization for ACS, developed stroke or the number op patients with combinations of these endpoints at 30 days and at one year after PCI.
Secondary safety endpoints are the number of patients with (non-)CABG-related major bleeding, major bleeding, minor bleeding, life threatening bleeding, fatal bleeding, intracranial bleeding, bleed requiring transfusion or the number of patients with combinations of these endpoints at at one year after PCI.
A secondary endpoint is the number of patients in whom the antiplatelet drug is prematurely discontinued or switched to another drug.

E.5.2.1 | Timepoint(s) of evaluation of this end point |
At 30 days and one year following PCI. |
