Prasugrel vs. Ticagrelor in Patients With Acute MI Treated With Primary PCI - PRAGUE-18
Contribution To Literature:
The PRAGUE-18 trial showed similar efficacy for either prasugrel or ticagrelor during primary PCI.
The goal of the trial was to evaluate treatment with prasugrel versus ticagrelor among patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).
Patients with STEMI undergoing primary PCI were randomized to prasugrel (n = 634) versus ticagrelor (n = 596).
- Total number of enrollees: 1,230 (the trial was stopped early due to futility)
- Duration of follow-up: 30 days
- Mean patient age: 62 years
- Percentage female: 23%
- Percentage diabetics: 20%
- Patients with STEMI undergoing primary PCI
- Patients with very high risk non-STEMI undergoing emergent PCI
- History of stroke
- Serious bleeding within the last 6 months
- Indication for anticoagulation therapy
- Administration of clopidogrel ≥300 mg before randomization
- >75 years of age and <60 kg
- Severe liver disease
- Current use of a strong CYP3A4 inhibitor
Other salient features/characteristics:
- 5.2% enrolled as a very high risk non-STEMI
The primary outcome, incidence of death, reinfarction, urgent target vessel revascularization, stroke, serious bleeding requiring transfusion, or prolonged hospitalization at 7 days, occurred in 4.0% of the prasugrel group versus 4.1% of the ticagrelor group (p = 0.94).
- Cardiovascular death, nonfatal MI, or stroke at 30 days: 2.7% versus 2.5% (p = 0.86), respectively, for prasugrel versus ticagrelor
- TIMI major bleeding at 30 days: 0.6% versus 0.7% (p = 0.85), respectively, for prasugrel versus ticagrelor
- Cardiovascular death, nonfatal MI, or stroke at 1 year: 6.6% versus 5.7% (p = 0.50), respectively, for prasugrel versus ticagrelor
Among patients with STEMI undergoing primary PCI, similar efficacy and bleeding was observed for either prasugrel or ticagrelor. Similar ischemic events were noted at 7 days and 1 year. Among such patients, the use of either agent is acceptable.
