Comparison of the Conor Sirolimus-eluting Coronary Stent to the Taxus Liberte Paclitaxel-eluting Coronary Stent in the Treatment of Coronary Artery Lesions

A Randomized, Multi-Center, Single-Blind Comparison of the Conor Cobalt Chromium Reservoir Based Stent With Sirolimus Elution Versus the TAXUS Liberte Paclitaxel-eluting Coronary Stent System in De Novo Native Coronary Artery Lesions

Summary

The purpose of this study is to evaluate the safety and effectiveness of the Conor Sirolimus-eluting Coronary Stent System in the treatment of coronary artery disease (a single atherosclerotic lesion) in native coronary arteries. The study will evaluate the outcomes of a new drug-eluting stent compared to an approved drug-eluting stent. While Cordis made a business decision to no longer pursue NEVO™ development and commercialization, the patients will be followed up as per protocol. This includes performing all protocol required follow-up visits and the collection and reporting of all safety information.

Detailed description

Restenosis remains a frequent cause of late failure following successful coronary angioplasty occurring in an estimated 20-40% of procedures performed. Coronary stents provide mechanical scaffolding that helps reduce restenosis by limiting the extent of elastic recoil and late vascular remodeling. Despite improvements over balloon angioplasty alone, restenosis following coronary stenting procedures has been cited to occur in 20-40% of cases and is primarily a result of neointimal hyperplasia. Thus, stents which are capable of delivering drugs to limit neointimal hyperplasia, in addition to providing mechanical support at the area of the lesion, have been developed to further limit the extent of restenosis following coronary stenting. There are several pharmacologic agents approved for use with drug-eluting stents.Two drugs have been widely studied in controlled clinical trials and real-world patient populations, sirolimus and paclitaxel. This study will evaluate a new sirolimus-eluting cobalt chromium coronary stent system compared to an approved paclitaxel-eluting coronary stent system in the treatment of single de novo coronary lesions in native coronary arteries. Subjects meeting qualification will be randomized in a 1:1 fashion to treatment with the Conor sirolimus-eluting coronary stent or to treatment with an approved paclitaxel-eluting coronary stent. All subjects will undergo angiographic follow-up at six months and complete clinical follow-up for a period of five years.

Conditions

• Coronary Atherosclerosis

Interventions

Type	Name	Description
DEVICE	NEVO™ Sirolimus-eluting Coronary Stent System	Intervention will consist of percutaneous coronary intervention for treatment of a single coronary lesion using standard coronary intervention techniques. Intervention in this arm will include treatment with the Conor Cobalt Chromium Sirolimus-eluting Coronary Stent System. Subjects assigned to the IVUS sub-study population will undergo intravascular ultrasound evaluation immediately post-stenting.
DEVICE	Drug-eluting stent (TAXUS Liberte Paclitaxel-eluting Coronary Stent System)	Intervention will consist of percutaneous coronary intervention for treatment of a single coronary lesion using standard coronary intervention techniques. Intervention in this arm will include treatment with the TAXUS Liberte Paclitaxel-eluting Coronary Stent System. Subjects assigned to the IVUS sub-study population will undergo intravascular ultrasound evaluation immediately post-stenting.
