简要总结
TAXUS ATLAS is a global, multi-center, single-arm, non-inferiority trial comparing results from patients treated with the TAXUS Liberté 38 mm stent to an historical TAXUS Express control. The control group is a case-matched, blended, long lesion subset population of TAXUS Express patients from the TAXUS IV and TAXUS V de novo clinical trials. The objective of the study is to evaluate clinical outcomes of TAXUS Liberté-SR 38 mm stent in de novo lesions and to assess the non-inferiority of TAXUS Liberté versus TAXUS Express. The TAXUS Liberté-SR stent is hypothesized to have comparable safety and efficacy to the TAXUS Express stent.

入选标准
- •Patient is at least 18 years old.
- •Eligible for percutaneous coronary intervention (PCI)
- •Documented stable angina pectoris or unstable angina pectoris with documented ischemia, or documented silent ischemia
- •Left ventricular ejection fraction (LVEF) of at least 25%
- •Acceptable candidate for coronary artery bypass grafting (CABG)
- •Patient or legal guardian understands the study requirements and the treatment procedures and provides written Informed Consent before any study-specific tests or procedures are performed
- •Willing to comply with all specified follow-up evaluations
- •Angiographic Inclusion Criteria:
- •Only one lesion (target lesion) may be treated with the study stent.However, one additional lesion in a non-target vessel may be treated during the index procedure with a commercially available bare metal stent, heparin-coated stent or TAXUS Express stent.
- •Successful predilation is mandatory for entry into study
- •Target lesion located within a single native coronary artery
- •Target lesion enrolled for treatment may be composed of multiple lesions (not more than 10mm between diseased segments) but must be completely covered by one study stent.
- •Cumulative target lesion length is greater than or equal to 26 mm and less than or equal to 34 mm (visual estimate)
- •Target lesion RVD is greater than or equal to 2.7 mm and less than or equal to 4.0 mm (visual estimate)
- •Target lesion diameter stenosis at least 50% (visual estimate)
- •Target lesion is de novo (i.e., a coronary lesion not previously treated)
排除标准
- •Known hypersensitivity to paclitaxel
- •Any previous, concurrent or planned treatment with a non-study anti-restenotic drug-coated or drug-eluting coronary stent.
- •Planned use of both the study stent and a non-study stent (i.e., commercial stent) in the treatment of the target vessel
- •Previous or planned treatment with intravascular brachytherapy in the target vessel
- •Planned CABG within 9-months post-index procedure
- •MI within 72 hours prior to the index procedure and/or creatine kinase(CK) >2x the local laboratory's ULN unless CK-MB is <2x ULN
- •Cerebrovascular Accident (CVA) within the past 6 months
- •Cardiogenic Shock
- •Acute or chronic renal dysfunction
- •Contraindication to ASA, or to both clopidogrel and ticlopidine
- •Thrombocytopenia or thrombocytosis
- •Active peptic ulcer or active gastrointestinal (GI) bleeding
- •Known allergy to stainless steel
- •Any prior true anaphylactic reaction to contrast agents
- •Patient is currently, or has been treated with paclitaxel or other chemotherapeutic agents within 12-months of the index procedure
- •Anticipated treatment with paclitaxel or oral rapamycin during any period in the 9-months after the index procedure
- •Male or female with known intention to procreate within 3 months after the index procedure
- •Female of childbearing potential with a positive pregnancy test within 7 days before the index procedure, or lactating
- •Life expectancy of less than 24 months due to other medical condition
- •Co-morbid condition(s) that could limit the patient's ability to participate in the study, compliance with follow-up requirements or impact the scientific integrity of the study
- •Currently participating in another investigational drug or device study that has not completed the primary endpoint or that clinically interferes with the endpoints of this study
- •Angiographic Exclusion Criteria:
- •Unprotected and protected left main coronary artery disease (patient with protected left main disease can be enrolled ONLY if the target lesion is in the RCA)
- •Target lesion is ostial in location (within 3.0 mm of vessel origin)
- •Target lesion and/or target vessel proximal to the target lesion is moderately or severely calcified by visual estimate
- •Target lesion and/or target vessel proximal to the target lesion is tortuous
- •Target lesion is located within or distal to a >60 degree bend in the vessel
- •Target lesion involves a bifurcation with a side branch vessel >2.0mm in diameter
- •Target lesion is totally occluded (TIMI flow <1), either at baseline or predilation
- •Angiographic presence of probable or definite thrombus
- •Pre-treatment of the target vessel at the index procedure is not allowed with any device except for predilation with balloon angioplasty or cutting balloon.
- •A previously treated lesion within the target vessel:
- •<15mm from the target lesion (visual estimate)
- •Performed </= 6 months from index procedure
- •>30% residual stenosis after previous treatment
