Key result
The EluNIR Ridaforolimus Eluting Coronary Stent System demonstrated angiographic and clinical results that were noninferior to the Medtronic Resolute stent DES.
Why the study?
To highlight the special characteristics and summarize relevant clinical data for the EluNIR Ridaforolimus Eluting Coronary Stent System.
The EluNIR Ridaforolimus-eluting stent is a novel DES with unique design features that has demonstrated noninferiority to the Resolute DES in clinical trials.
Introduction: First-generation drug-eluting stents (DES) were developed and indeed proved their superiority compared to bare-metal stent in minimizing neo-intimal hyperplasia and in-stent restenosis (ISR), overall, reducing target vessel revascularization (TVR). Newer-generation DES are characterized by thinner struts, more biocompatible and either durable, biodegradable or polymer-free surfaces, better device profile and refined drug elution.Area covered: The EluNIRTM (Medinol, Tel Aviv, Israel) Ridaforolimus Eluting Coronary Stent System is a new DES with unique properties. In this review, we highlight the special characteristics of the stent and summarize relevant clinical data. The EluNIRTM was studied in two clinical trials, the NIREUS trial and the larger, pivotal, BIONICS trial. These trials collectively provide data on the safety, performance, and efficacy of the device.Expert commentary: The newly FDA-approved EluNIRTM stent features an elastomeric durable polymer which elutes a novel drug, Ridaforolimus. The stent has thin struts with variable widths and a delivery catheter with a spring tip. These characteristics may explain the good angiographic and clinical results of this stent, which were noninferior to the FDA-approved Medtronic ResoluteTM stent DES.

Savvoulidis et al. (2018) conducted a review in Coronary artery disease. EluNIR Ridaforolimus Eluting Coronary Stent System vs. Medtronic Resolute stent DES was evaluated. The EluNIR Ridaforolimus Eluting Coronary Stent System demonstrated angiographic and clinical results that were noninferior to the Medtronic Resolute stent DES.
