Trial Outcomes & Findings for Study Comparing the CYPHER® ELITE™ to the CYPHER® Bx VELOCITY® Sirolimus-Eluting Stent Systems (NCT NCT00715884)

NCT ID: NCT00715884

Last Updated: 2014-01-20

Results Overview

The primary endpoint for this study is the percentage of participants who experienced Target Lesion Failure (TLF) during the 12 months post-procedure. A TLF event is defined as clinically-driven target lesion revascularization, target vessel myocardial infarction, or cardiac death that could not be clearly attributed to a vessel other than the target vessel at 12 months post-procedure.

TLR is defined as any "clinically-driven" repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel. Clinically-driven revascularizations are those in which the patient has a positive functional study, ischemic electrocardiogram (ECG) changes at rest in a distribution consistent with the target vessel, or ischemic symptoms, and an in-lesion diameter stenosis 50 percent by QCA.

Protocol defined Stent thrombosis include both Early and Late Thrombosis. Early thrombosis is defined as composite thirty-day ischemic endpoint including death, Q-wave MI, or subabrupt closure requiring revascularization. Late thrombosis is defined as myocardial infarction occurring \> 30 days after the index procedure and attributable to the target vessel with angiographic documentation (site-reported or by qualitative coronary angiography) of thrombus or total occlusion at the target site and freedom from an interim revascularization of the target vessel.

Academic Research Consortium (ARC) defines STENT THROMBOSIS as consisting of the following: 1. DEFINITE - Angiographic or pathologic confirmation; 2. PROBABLE - Any unexplained death within the first 30 days or Any MI (related to documented acute ischemia and without another obvious cause) in the territory of the stent; 3. POSSIBLE - Any unexplained death \> 30 days. ARC Stent thrombosis should be reported as a cumulative value at the different time points and with the different separate time points.
