Ultimaster Nagomi™ Sirolimus Eluting Coronary Stent System in Complex PCI Patients

The NAGOMI COMPLEX PMCF (Post-Market Clinical Follow-up) study has been designed to expand the knowledge about outcomes with the Ultimaster Nagomi™ sirolimus eluting coronary stent system (Ultimaster Nagomi™) in complex PCI subjects. The features for a complex PCI are based upon subgroup analysis of earlier published studies.

The study is a prospective, multi-center, post-market, non-interventional, observational, single-arm study. Subjects with an indication for a PCI according to current European Society of Cardiology (ESC) or national guidelines will be treated with the Ultimaster Nagomi™ in accordance with the intended use. The PCI procedure will be per hospital routine including the option, as per physician preference, to assess the functional severity of the lesion, perform intra-coronary imaging, use lesion preparation devices or to perform a staged procedure. Also, post-procedural anti-platelet medication will be per ESC or national guidelines. The primary endpoint is Target Lesion Failure (TLF) defined as Cardiovascular Death (CD), Target-Vessel related Myocardial Infarction (TV-MI) and Clinically Driven Target Lesion Revascularization (CD-TLR) at 1 year. Secondary endpoints are a broad set of clinical endpoints defined by the Academic Research Consortium-II to fully characterize the performance of the Ultimaster Nagomi™ stent. Clinical events will be adjudicated by an independent Clinical Events Committee (CEC) to ensure a consistent assessment versus the event definitions. The Data Monitoring Committee (DMC) will simultaneously conduct regular review for accumulating data to ensure proper safety data monitoring. Core lab analysis of the baseline angiograms of bifurcation lesions by Quantitative Coronary Angiography (QCA) will be included. Procedural resource data will be collected for health-economic analysis. Subject reported outcomes will be documented using the EQ-5D-5L questionnaire and the Seattle Angina Questionnaire (SAQ) for the assessment of the quality of life and angina status, respectively. The study will enroll 3,000 patients from European sites. Follow-up will be 2 years, except for subjects in whom no Ultimaster Nagomi™ stent was implanted and subjects that do not meet the inclusion criteria for a complex PCI as ascertained after the index procedure. These subjects will be followed until discharge.
