SYNTAX Study: TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries

Phase 3
Conditions
Coronary Artery Disease
Interventions
Device: Polymer-based Paclitaxel-Eluting TAXUS Express2-SR Stent
Procedure: Coronary Artery Bypass Surgery
Registration Number
NCT00114972
Lead Sponsor
Boston Scientific Corporation
Brief Summary

The SYNTAX trial is designed to determine the best treatment for patients with complex coronary disease (blocked or narrowed arteries in both the right and left sides of the heart) by randomizing patients to receive either percutaneous coronary intervention (PCI) with polymer-based paclitaxel-eluting TAXUS stents or to coronary artery bypass surgery (CABG).

Detailed Description

Due to the introduction of drug-eluting stents (DESs) and to improvements in therapy for both percutaneous coronary intervention (PCI) and coronary artery bypass surgery (CABG) patients, PCI is challenging CABG as the gold standard for treatment of three vessel (3VD) and left main (LM) coronary disease.

SYNTAX is a novel, randomized trial with nested registries comparing PCI with paclitaxel-eluting TAXUS stents to CABG for 3VD and LM patients to evaluate the best treatment for these patients with complex coronary disease.

Patients at participating centers will be evaluated by both a cardiothoracic surgeon and by an interventional cardiologist.

Those patients who are determined to be eligible for treatment by both PCI and CABG will be randomized to receive either PCI with a polymer-based paclitaxel-eluting TAXUS stent or CABG.

Patients who are determined to be unsuitable for treatment by PCI will be treated by CABG and will be entered into a CABG registry to help define the patient population in which stenting continues to be an unacceptable treatment option.

Similarly, patients who are determined to be unsuitable for treatment by CABG will be treated by PCI, using any interventional techniques or devices with or without the use of DES, and entered into a PCI registry to help define the patients for whom CABG is considered inappropriate.

Primary Outcome Measures
NameTimeMethod
Primary Clinical Endpoint of 12-Month Binary MACCE.12 months post enrollment

Number of participants at primary clinical endpoint of 12-Month binary MACCE. MACCE is defined as: all cause death, cerebrovascular event (stroke), cocumented myocardial infarction, repeat revascularization (PCI and/or CABG).

12-month Composite Safety Endpoint.12 months after enrollment

Number of participants at 12-month composite safety endpoint. Composite safety endpoint combines: all cause death, cerebrovascular event (stroke), and documented myocardial infarction.

Repeat Revascularization (PCI and/or CABG).12 Months post enrollment

Number of participants with repeat revascularization (PCI and/or CABG).

Secondary Outcome Measures
NameTimeMethod
Overall MACCE at 1 Month Post-procedure and at 6 Months, 3 Years, and 5 Years Post-allocation.1 month after procedure and 6 months, 3 years, and 5 years post allocation

Number of participants with Overall MACCE at 1 month post-procedure and at 6 months, 3 years, and 5 years post-allocation.

Individual Components of MACCE at 1 Month Post-procedure.1 month after procedure

Number of participants with individual components of MACCE at 1 month post-procedure. The individual components of MACCE are: all cause death, stroke, documented myocardial infarction, repeat revascularization.

Individual Components of MACCE at 6 Months Post-allocation.6 months post allocation

Number of participants with individual components of MACCE at 6 months post-allocation. The individual components of MACCE are: all cause death, stroke, documented myocardial infarction, repeat revascularization.

Individual Components of MACCE at 1 Year Post-allocation.1 year post allocation

Number of participants with individual components of MACCE at 1 year post-allocation. The individual components of MACCE are: all cause death, stroke, documented myocardial infarction, repeat revascularization.

Freedom From MACCE and Its Components at 1 Year Post-allocation.1 year post allocation

Number of participants with freedom from MACCE and its components at 1 year post-allocation. Freedom from MACCE is defined as no MACCE nor any of the individual components of MACCE (all cause death, stroke, documented myocardial infarction, repeat revascularization).
