Cobalt Chromium Stent With Antiproliferative for Restenosis II Trial (COSTAR II)

Multi-Center, Single-Blind, Two-Arm, Randomized, Controlled, Non Inferiority Trial of the Conor CoStar Paclitaxel-Eluting Coronary Stent System vs the TAXUS DES in Patients With De Novo Lesions of the Native Coronary Arteries

The purpose of this study is to evaluate the safety and effectiveness of the investigational stent CoStar™ Paclitaxel-Eluting Coronary Stent- a reservoir based DES system in comparison to a surface coated DES stent (TAXUS™ Express2™ Paclitaxel-Eluting Coronary Stent) in the treatment of single-vessel (one blood vessel) and multi-vessel (two or three blood vessels) coronary artery disease.

Non -inferiority in 8-month Major Adverse Cardiac Events (MACE) and in-segment late lumen loss at 9 months between the CoStar™ Paclitaxel-Eluting Coronary Stent System and the TAXUS™ Express2™ Drug Eluting Coronary Stent System for the treatment of a single de novo lesion per vessel in patients with single and multi-vessel coronary disease.
