RENAISSANCE Clinical Trial
Overview The RENAISSANCE Trial was a prospective, multi-center, single arm study designed to evaluate the Express SD Renal Premounted Stent System in the treatment of atherosclerotic lesions in the aortorenal ostium.
The primary objective was to demonstrate superiority of the duplex triggered, angiographically-confirmed binary restenosis rate at 9-months over the 40% pre-specified Objective Performance Criterion (OPC) representative of PTRA.
Trial Design The RENAISSANCE Trial enrolled 100 patients (117 lesions) with de novo or restenotic ostial atherosclerotic lesions ≤15mm long in vessels between 4.0 and 7.0mm diameter with diameter stenosis ≥70%.
Outcomes Primary Endpoint: 21.3% binary in-stent restenosis rate at 9-months, defined as the proportion of target lesions with ≥50% diameter stenosis based on angiographic core lab assessment.
*Denominator consists of number of subjects who either died prior to late follow-up window and/or had follow-up to at least the early follow-up window.
**Denominator consists of number of subjects who either had CEC adjudicated device or procedure related death prior to late follow-up window and/or had follow-up to at least the early follow-up window.
†Matched data by time point.
