Phase 2 pilot study evaluates ticagrelor monotherapy safety after stenting for acute MI
This is a single-center, single-arm, prospective phase II pilot study designed to evaluate the initial safety of ticagrelor monotherapy following coronary artery stenting for acute myocardial infarction. The study enrolled 200 patients who underwent stenting due to either NSTEMI or STEMI. All patients underwent invasive coronary angiography and clinically indicated Percutaneous Coronary Intervention (PCI), which was performed using EES (everolimus-eluting stents) and OCT guidance utilizing the MLDMAX algorithm (Morphology, Length, Diameter, Medial dissection, Apposition, Xpansion). Eligibility was assessed after PCI completion. Patients were provided a drug diary to document and remind them of twice-daily ticagrelor 90mg administration. A Data Safety Monitoring Board (DSMB) was tasked with continuously reviewing patient outcomes. The DSMB was scheduled to convene after the first 50 patients were recruited and at least 30 of those patients had either reached the 3-month follow-up or experienced the primary outcome. The primary endpoint for the study was the composite of cardiac death, spontaneous myocardial infarction, or definite or probable stent thrombosis occurring within 3 months. The study, led by the Vastra Gotaland Region, started on December 14, 2021, and had a primary completion date of June 26, 2025. The abstract does not report any results, safety data, or statistical outcomes from the study.
