Ultimaster Nagomi™ Sirolimus Eluting Coronary Stent System in Complex PCI Patients (NAGOMI COMPLEX)
Clinical Trial NCT05705973 (NAGOMI COMPLEX) is an observational study for Cardiovascular Disease, Coronary Artery Occlusion, Ischemic Heart Disease that is active, not recruiting. It started on 25 April 2023 with plans to enroll 3,000 participants. Led by Terumo Europe N.V., it is expected to complete by 29 April 2027. The latest data from ClinicalTrials.gov was last updated on 20 May 2025.
Brief Summary
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.
Detailed Description
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.

N/A | Ultimaster Nagomi™ The Ultimaster NagomiTM Sirolimus eluting coronary stent system with Rapid Exchange Balloon Delivery System consists of a balloon expandable intra-coronary L605 cobalt chromium (CoCr) stent with abluminal drug eluting coating, that consists of a blend of Sirolimus and Poly(D,L-lactide-co-caprolactone), pre-mounted onto a high pressure, semi-compliant balloon delivery catheter |

Noncardiovascular death may include death from malignancy, death resulting from pulmonary causes, death caused by infection (including sepsis), death resulting from gastrointestinal causes, death resulting from accident/trauma, death caused by other noncardiovascular organ failure, death resulting from other.
Undetermined cause of death is defined as a death not attributable to any other category because of the absence of any relevant source documents. | at index procedure, 30 days, 6 months, 1 year, and 2 years |

The second part of the questionnaire contains a standard vertical 20-cm visual analog scale that is calibrated from 'the worst health you can imagine' (scored 0) at its base to 'the best health you can imagine' (scored 100) at its apex. | at baseline, 30 days, 6 months, 1 year, and 2 years |
Angina status assessment Seattle Angina Questionnaire (SAQ) | Angina status will be assessed through the Seattle Angina Questionnaire (SAQ).

QCA of the index procedure angiogram for a subset of patients with a Complex Bifurcation Lesion (CBL) | Luminal dimensions of bifurcation lesions will be measured by off-line quantitative coronary angiography by a central core laboratory.
The objective of the QCA is to quantitate and express the benefit of the Proximal Optimisation Technique (POT). The POT balloon positioning is of importance in this technique as well as the balloon diameter to obtain optimal stent apposition in the main branch. | procedure |
