COBRA PZF™ Coronary Stent for Early Healing, Thrombus Inhibition, Endothelialization and Avoiding Long-Term DAPT

Study Overview
=================
Brief Summary
-----------------
This is a prospective, multi-center, non-randomized, single arm clinical trial that will be conducted at up to 40 sites in the United States and Outside United States (OUS). This study will enroll patients with symptomatic ischemic heart disease due to a single de novo lesion contained within a native coronary artery with reference vessel diameter between 2.5 mm and 4.0 mm and lesion length ≤ 24 mm that is amenable to percutaneous coronary intervention (PCI) and stent deployment. All patients will be followed at 30 days, 6 months, 9 months, 1 year and annually for 5 years post index stenting procedure.

Detailed Description
-----------------
The main objective of this study is to evaluate the safety and effectiveness of the COBRA PzF™ Coronary Stent System in the treatment of de novo lesions in native coronary arteries. The primary endpoint will be the incidence of target vessel failure (TVF, see definition below) within 270 days of treatment with the COBRA PzFTM Coronary Stent System. This rate will be compared to a performance goal derived using a meta-analysis from published historical data of the standard-of-care therapy, coronary stenting with bare metal stents. PRIMARY STUDY HYPOTHESIS The CeloNova COBRA PzFTM Study will have a primary endpoint (TVF) rate less than 19.62% and by that will meet the performance goal for bare metal stents, per the results of the historical control group combined with relevant data for EXPRESS™, Driver™, Presillion/Presillion plus™ and NIRFLEX™ stents. SECONDARY STUDY HYPOTHESIS The powered secondary endpoint for this trial is that the CeloNova COBRA PzFTM Study will have a 9-month in-stent late loss (LL) that meets or is lower than the performance goal of 1.1 mm. NUMBER OF PATIENTS 296 patients will be enrolled to account for loss to follow-up, which is estimated to be approximately 5% (resulting in 281 evaluable patients), at up to 40 sites in United States and OUS. At least 40% of subjects will be enrolled in the United States. PRIMARY ENDPOINT Target vessel failure (TVF), defined as cardiac death, target vessel myocardial infarction (MI) [Q wave or non-Q wave, ARC-definition], or clinically driven target vessel revascularization (TVR) by percutaneous or surgical methods within 270 days post-procedure.
