About this study

Official title: A Randomized, Controlled Trial of the Medtronic Endeavor Drug (ABT-578) Eluting Coronary Stent System Versus the Taxus Paclitaxel-Eluting Coronary Stent System in De Novo Native Coronary Artery Lesions

The purpose of this study is to assess the equivalence in safety and efficacy of the Endeavor Drug Eluting Coronary Stent System when compared to the Taxus Paclitaxel-Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries with a reference vessel diameter (RVD) of 2.5-3.5 mm.

Read the detailed description

The ENDEAVOR IV Trial is a prospective, multi-center, randomized, two-arm, single-blind trial that will enroll a total of 1,548 patients at up to 80 sites in the US. The ENDEAVOR IV Trial will assess if the Endeavor stent is equivalent in safety and efficacy to the Taxus stent for the treatment of single de novo lesions in native coronary arteries with a RVD of 2.5-3.5 mm.

Questions about this trial

What is this clinical trial studying?

A study testing Coronary Artery Stenting in people with Coronary Artery Disease, run by Medtronic Vascular at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. 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 20 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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.

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?

Target vessel failure (TVF) rate (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 NCT00217269, which also lists 7 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 20 Apr 2012.
