About this study

Official title: A Multi-center, Single-arm Study of the TAXUS Liberté™-SR Stent for the Direct Stenting Treatment of Patients With de Novo Coronary Artery Lesions

TAXUS ATLAS Direct Stent is a global, multi-center, single-arm, noninferiority trial comparing results from patients in whom the TAXUS Liberté stent was directly implanted (direct stenting) versus results from patients in whom implantation with the TAXUS Liberté stent was preceded by balloon angioplasty (pre-dilatation). The Control group consists of patients in the main TAXUS ATLAS trial, in which pre-dilatation was mandatory. The primary objective is to compare outcomes of direct stenting with balloon catheter pre-dilatation. The primary hypothesis is that late outcomes with direct stenting of the TAXUS™ Liberté Paclitaxel-Eluting Coronary Stent System will be non-inferior to conventional implantation with balloon catheter pre-dilatation

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing TAXUS Liberté™-SR in people with Coronary Artery Disease, run by Boston Scientific Corporation at 25 sites in 4 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, Taiwan. 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?

Analysis segment percent diameter stenosis 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 NCT00371423, 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.
