TAXUS PERSEUS Small Vessel

Phase 3

Completed

Conditions: Coronary Artery Disease

Interventions: Device: Percutaneous Coronary Intervention (PCI) with paclitaxel-eluting stent (TAXUS Element) implantation

Registration Number: NCT00489541

Lead Sponsor: Boston Scientific Corporation

Brief Summary: The purpose of the TAXUS PERSEUS Small Vessel 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 20 mm in length in native coronary arteries of ≥ 2.25 mm to \< 2.75 mm diameter.

Detailed Description: This is a prospective, multi-center, single-arm superiority trial to assess the TAXUS® Element™ Paclitaxel-Eluting Coronary Stent System for the treatment of de novo atherosclerotic lesions of ≤20 mm in length in native coronary arteries with visual RVD of ≥ 2.25 mm to \< 2.75 mm diameter.

Two hundred twenty-four (224) subjects will be treated with the TAXUS Element stent at a maximum of 35 clinical sites. Follow-up at 30 days, 9 months including angiography) and 1 year will be completed in all subjects enrolled in the study. Eligible subjects will have annual follow-up until 5 years post-index procedure.

Angiographic Inclusion Criteria:

Target Lesion
- Target lesion located in native coronary artery
- Target lesion must be de novo
- Target lesion diameter stenosis ≥ 50%
- Reference vessel diameter (RVD) ≥ 2.25 mm to < 2.75 mm
- Cumulative target lesion length ≤ 20 mm (area to be treated may be composed of multiple lesions but must be completely coverable by one study stent)
- Target lesion is successfully pre-dilated
One non-target lesion may be treated in a non-target vessel as follows:
- Non-target lesion in non-target vessel must be treated with commercially available TAXUS stent if use of drug eluting stent required
- Treatment must be deemed a clinical angiographic success, without requiring use of unplanned additional stents(s)
- Treatment must be completed prior to treatment of target vessel

Angiographic Exclusion Criteria:

Target lesion located in left main artery, whether protected or unprotected
Target lesion is a chronic total occlusion (TIMI flow ≤ 1)
Target lesion is restenotic
Target lesion is located in a saphenous vein graft or mammary artery graft
Target lesion is accessed via saphenous vein graft or mammary artery graft
Target lesion is < 5 mm from bare metal stent (BMS)
Target lesion < 5 mm from ostium
Target lesion < 5 mm from side branch vessel ≥ 2.0 mm in diameter (Exceptions: subject may be enrolled if side branch is 100% occluded or if side branch is protected with a patent graft)
Untreated lesions with ≥ 50% diameter stenosis or thought to impair flow remaining in target vessel at a location with ≥ 2.0mm RVD
Target lesion and/or target vessel proximal to target lesion moderately severely calcified
Target lesion and/or target vessel proximal to target lesion severely tortuous
Target lesion located within or distal to a > 60° bend in target vessel
Target vessel with angiographic presence of probable or definite thrombus
Unprotected left main coronary artery disease
Protected left main coronary artery disease with target lesion in Left Anterior Descending artery (LAD) or Left Circumflex artery (LCx). Subject may be enrolled if only lesion is target lesion in Right Coronary Artery (RCA)

Primary Outcome Measures

Name	Time	Method
In-stent Late Loss Measured by Quantitative Coronary Angiography (QCA)	9 months post-index procedure	Post-procedure minimum lumen diameter (mm) minus follow-up minimum lumen diameter as determined by quantitative angiography. Minimum lumen diameter is measured within the stent at each time point.

Secondary Outcome Measures

Name	Time	Method
Number of Participants With 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.	12 months post-index procedure	The number of participants who experience a TLF through 365 days post-procedure out of the patients 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.
