About this study
Official title: TAXUS ATLAS SMALL VESSEL: A Multi-center, Single-arm Study of the TAXUS Liberté™-SR Stent for the Treatment of Patients With de Novo Coronary Artery Lesions in Small Vessels
TAXUS ATLAS Small Vessel is a global, multi-center, single-arm, trial of patients with coronary arteries less than 2.5 mm in diameter who are treated with the TAXUS Liberté stent versus an historical TAXUS Express control derived from a subset of lesion-matched TAXUS V patients treated with a 2.25 mm stent. The objective of the study is to evaluate clinical and angiographic outcomes of TAXUS Liberté-SR 2.25 mm stent in de novo lesions. The hypothesis is that the TAXUS Liberté-SR stent has non-inferior safety and efficacy to the TAXUS Express-SR stent in the treatment of de novo lesions in small coronary vessels.
Read the detailed description
TAXUS ATLAS Small Vessel is a global, multi-center, single-arm, trial of patients receiving the TAXUS Liberté-SR 2.25 mm paclitaxel-eluting stent. The results will be compared with two different historical control groups. The first control group consists of a subset of lesion-matched TAXUS V patients treated with a 2.25 mm TAXUS Express-SR paclitaxel-eluting stent. The objective of this analysis is to evaluate clinical and angiographic outcomes of TAXUS Liberté-SR 2.25 mm stent in de novo lesions versus the TAXUS Express-SR stent. The hypothesis is that the TAXUS Liberté-SR stent has non-inferior safety and efficacy to the TAXUS Express-SR stent in the treatment of de novo lesions in small coronary vessels. The second control group consists of a subset of lesion-matched TAXUS V patients treated with either a 2.5 mm or a 2.25 mm bare metal Express stent. The objective of this analysis is to evaluate clinical and angiographic outcomes of TAXUS Liberté-SR 2.25 mm stent in de novo lesions versus the Express bare metal stent. The hypothesis is that the TAXUS Liberté-SR stent has superior safety and efficacy to the Express bare metal stent in the treatment of de novo lesions in small coronary vessels.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing TAXUS Liberté-SR, TAXUS™ Express2 and Express2 in people with Coronary Artery Disease, run by Boston Scientific Corporation at 25 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 25 sites in United States, New Zealand, Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percent diameter stenosis - analysis segment at 9 months (time frame: 9 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00371748, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2012.
