Brief Summary:
The purpose of the TAXUS PERSEUS Workhorse trial is to evaluate the safety and efficacy of the next-generation Boston Scientific TAXUS paclitaxel-eluting coronary stent system (TAXUS® ElementTM) for the treatment of de novo atherosclerotic lesions of up to 28 mm in length in native coronary arteries of 2.75 mm to 4.0 mm diameter.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: Percutaneous coronary intervention (PCI) with paclitaxel-eluting stent (TAXUS Element) implantation Device: Percutaneous coronary intervention (PCI) with paclitaxel-eluting stent (TAXUS Express) placement Phase 3

Detailed Description:

This is a prospective, 3:1 randomization, multi-center trial to assess the TAXUS® Element™ Paclitaxel-Eluting Coronary Stent System for the treatment of de novo atherosclerotic lesions of up to 28 mm in length in native coronary arteries ≥ 2.75 mm and ≤ 4.0 mm in diameter, compared to a control group of TAXUS Express2 Paclitaxel-Eluting Coronary Stent System .

One thousand two hundred sixty-four (1264) subjects will be treated with either the TAXUS® Element™ stent or the TAXUS® Express2 ™stent at a maximum of 100 clinical sites. Randomization to treatment group will be unbalanced 3:1 towards the test group to gain maximum clinical experience with the new TAXUS® Element™ platform. Follow-up at 30 days, 9 months and 12 months will be completed in all subjects enrolled in the study. Angiographic follow-up at 9 months will be completed in a subset of three hundred thirty (330) subjects enrolled in the study. Subjects will be randomly allocated to the angiographic subset at participating sites through the Interactive Voice Response System (IVRS).

Eligible subjects will have annual follow-up until 5 years post-index procedure.

Primary Outcome Measures :
  1. Target Lesion Failure (TLF) at 12 Months Post-index Procedure. TLF is Defined as Any Ischemia-driven Revascularization of the Target Lesion, Myocardial Infarction (Q-wave and Non-Q-wave), or Death Related to the Target Vessel. [ Time Frame: 12 months post-index procedure ]
    The number of participants who experience a TLF through 365 days post-procedure out of the participants who have either had a TLF within 365 days post-procedure or who were TLF-free with last follow-up at least 335 days post-procedure.

Secondary Outcome Measures :
  1. In-segment Percent Diameter Stenosis at 9 Months Post-index Procedure [ Time Frame: 9 months post-index procedure ]
    The minimum lumen diameter in the analysis segment at 9-months post-index procedure, divided by the reference vessel diameter at baseline. The analysis segment ("in-segment") is defined as the proximal edge, stented area, and the distal edge, where each edge segment contains up to 5mm immediately outside the stent.
