About this study

Official title: A Randomized, Multi-Center, Single-Blind Comparison of the Conor Cobalt Chromium Reservoir Based Stent With Sirolimus Elution Versus the TAXUS Liberte Paclitaxel-eluting Coronary Stent System in De Novo Native Coronary Artery Lesions

The purpose of this study is to evaluate the safety and effectiveness of the Conor Sirolimus-eluting Coronary Stent System in the treatment of coronary artery disease (a single atherosclerotic lesion) in native coronary arteries. The study will evaluate the outcomes of a new drug-eluting stent compared to an approved drug-eluting stent.

While Cordis made a business decision to no longer pursue NEVO™ development and commercialization, the patients will be followed up as per protocol. This includes performing all protocol required follow-up visits and the collection and reporting of all safety information.

Read the detailed description

Restenosis remains a frequent cause of late failure following successful coronary angioplasty occurring in an estimated 20-40% of procedures performed. Coronary stents provide mechanical scaffolding that helps reduce restenosis by limiting the extent of elastic recoil and late vascular remodeling. Despite improvements over balloon angioplasty alone, restenosis following coronary stenting procedures has been cited to occur in 20-40% of cases and is primarily a result of neointimal hyperplasia. Thus, stents which are capable of delivering drugs to limit neointimal hyperplasia, in addition to providing mechanical support at the area of the lesion, have been developed to further limit the extent of restenosis following coronary stenting. There are several pharmacologic agents approved for use with drug-eluting stents.Two drugs have been widely studied in controlled clinical trials and real-world patient populations, sirolimus and paclitaxel.

This study will evaluate a new sirolimus-eluting cobalt chromium coronary stent system compared to an approved paclitaxel-eluting coronary stent system in the treatment of single de novo coronary lesions in native coronary arteries. Subjects meeting qualification will be randomized in a 1:1 fashion to treatment with the Conor sirolimus-eluting coronary stent or to treatment with an approved paclitaxel-eluting coronary stent. All subjects will undergo angiographic follow-up at six months and complete clinical follow-up for a period of five years.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NEVO™ Sirolimus-eluting Coronary Stent SystemDevice

    Intervention will consist of percutaneous coronary intervention for treatment of a single coronary lesion using standard coronary intervention techniques. Intervention in this arm will include treatment with the Conor Cobalt Chromium Sirolimus-eluting Coronary Stent System. Subjects assigned to the IVUS sub-study population will undergo intravascular ultrasound evaluation immediately post-stenting.

  • Drug-eluting stent (TAXUS Liberte Paclitaxel-eluting Coronary Stent System)Device

    Also called Taxus Liberte Paclitaxel-eluting Coronary Stent System

    Intervention will consist of percutaneous coronary intervention for treatment of a single coronary lesion using standard coronary intervention techniques. Intervention in this arm will include treatment with the TAXUS Liberte Paclitaxel-eluting Coronary Stent System. Subjects assigned to the IVUS sub-study population will undergo intravascular ultrasound evaluation immediately post-stenting.

  6. Device Success

    Measured: Procedural

  7. Lesion success

    Measured: Procedural

  8. Procedure Success

    Measured: Hospital Discharge

  9. Angiographic in-stent and in-segment binary restenosis.

    Measured: 6 months

  10. In-stent minimum lumen diameter

    Measured: 6 months

  11. Percent volume obstruction of the stent by intravascular ultrasound evaluation

    Measured: 6 months

  12. Patient reported outcomes as measured by three standardized quality of life surveys.

    Measured: Baseline, 30 days, 6 months and 12 months

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted1 Feb 2008 (estimated)
  2. Study startMar 2008
  3. Primary completionMay 2009
  4. Study completionOct 2012

Why it stopped: The NEVO™ stent will not be commercialized. Cordis have decided to close the study after 3 years. This decision took the absence of safety signals into account.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 31 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: stopped early, as of the sponsor's last update on 25 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Brazil, New Zealand. 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 was stopped early (reason given: The NEVO™ stent will not be commercialized. Cordis have decided to close the study after 3 years. This decision took the absence of safety signals into account.). Results are not available in the source record.

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?

Angiographic endpoint of in-stent late lumen loss as measured by QCA. (time frame: 6 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 NCT00606333, which also lists 3 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 25 Oct 2012.
