PRAGUE-18: Comparison of Prasugrel and Ticagrelor in the Treatment of Acute Myocardial Infarction
Study Details
Study Description
Brief Summary
This study evaluates the efficacy of Prasugrel and Ticagrelor in the treatment of acute myocardial infarction.
Condition or Disease | Intervention/Treatment | Phase |
---|---|---|
Phase 4 |
Detailed Description
Study objectives:
-
Compare the efficacy and safety of prasugrel and ticagrelor in acute myocardial infarction treated with emergent PCI.
-
Assess the safety of switching to clopidogrel after remission of the acute phase of MI in patients for whom economic barriers do not allow to continue treatment with prasugrel or ticagrelor. All randomized patients with acute myocardial infarction have been treated with standard therapeutic procedures in accordance with the guidelines of European Society of Cardiology (ESC). Participation of patients in the study is not connected to any deviations from the ESC guidelines recommendations.

Outcome Measures
Primary Outcome Measures
- Composite primary outcome measure consisting of Death / Re-infarction / Stroke / Serious bleeding requiring transfusion or prolonged hospitalization / Urgent Target Vessel Revascularization. [Within 7 days after Randomization.]
Definitions: Death defined as summary of death from any cause. Re-infarcion defined according to the Third Universal Definition of Myocardial Infarction. Stroke defined as the rapid onset of new neurological deficit caused by an ischemic or hemorrhagic central nervous system event with symptoms that lasted at least 24 hours after onset or leading to death. Urgent Target Vessel Revascularization defined as a new emergent/urgent revascularization of the vessel dilated at the initial procedure driven by recurrent signs of ischemia occurring after completion of initial PCI. Units: The percentage of randomized patients is the total number of randomized patients experiencing Death / Re-infarction / Stroke / Serious bleeding requiring transfusion or prolonged hospitalization / Urgent Target Vessel Revascularization divided by number of randomized patients in the treatment arm multiplied by 100. Primary endpoint is adjudicated by the Independent Control committee
Secondary Outcome Measures
- Composite secondary outcome measure consisting of Cadiovascular death / Non-fatal myocardial infarction / Stroke. [Within 30 days and one year after Randomization.]
Definition: Cardiovascular death defined as a death with a demonstrable cardiovascular cause, or any death that is not clearly attributable to a non-cardiovascular cause. Non-fatal myocardial infarction must be distinct from the index event and is defined according to the Third Universal Definition of Myocardial Infarction. Units: The percentage of randomized patients is the total number of randomized patients experiencing Cadiovascular death / Non-fatal myocardial infarction / Stroke divided by number of randomized patients in the treatment arm multiplied by 100.
- Stent thrombosis. [Within 30 days and one year after Randomization.]
Definition: Academic Research Consortium (ARC) criteria were used to define ST. Units: The percentage of randomized patients is the total number of randomized patients experiencing Stent thrombosis divided by number of randomized patients in the treatment arm multiplied by 100.
- Occurence of bleeding according to the TIMI and BARC criteria. [Within 30 days and one year after Randomization.]
TIMI criteria - Thrombolysis In Myocardial Infarction Criteria BARC criteria - Bleeding Academic Research Consortium criteria Units: The percentage of randomized patients is the total number of randomized patients experiencing bleeding according to the TIMI and BARC criteria divided by number of randomized patients in the treatment arm multiplied by 100.
Other Outcome Measures
- Composite outcome measure consisting of Cadiovascular death / Non-fatal myocardial infarction / Stroke in patients with Killip III/IV. [Within 7 days after Randomization.]
The percentage of randomized patients is the total number of randomized patients with Killip class III or IV experiencing Cardiovascular death / Non-fatal myocardial infarction / Stroke divided by number of randomized patients with Killip class III or IV in the treatment arm multiplied by 100.
