About this study

Official title: A Prospective, Multi-Center, Post-Market Surveillance Study to Assess the Clinical Efficacy and Fusion Rates of the Zimmer TM Ardis Interbody Fusion System

This study is a post-market clinical follow-up study to fulfill the post-market surveillance obligations according to Medical Device Directive and MEDDEV 2.12-2_Rev2_January 2012. The data collected from this study will serve the purpose of confirming safety and performance of the TM Ardis implant. The goal of this study is to demonstrate that implant is effective in reducing patient disability.

Read the detailed description

This study is a post-market clinical follow-up (PMCF) study to fulfill the post-market surveillance obligations according to Medical Device Directive and MEDDEV 2.12-2_Rev2_January 2012. The data collected from this study will serve the purpose of confirming safety and performance of the TM Ardis implant. The goal of this study is to demonstrate that implant is effective in reducing patient disability, which will be assessed with the ODI questionnaire.

What participants receive

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

  • TM-Ardis InterbodyDevice

    Also called Interbody Cage

    The TM Ardis implant is a single device manufactured wholly from Trabecular Metal™ (porous tantalum) material, a highly porous, three-dimensional biomaterial designed for biologic fixation. is indicated for use with autogenous bone graft as an intervertebral body fusion device at one or two contiguous levels in the lumbosacral region (L2- S1) in the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvement in ODI score

    mean change in score of the ODI from baseline to 24 months post surgery. A 15 point improvement in ODI score will be considered as a success.

    Measured: 24 months

Secondary outcomes (6)
  1. Safety - Adverse Events

    All adverse events will be assessed by incidence and time to resolution of postoperative device-related complications and serious adverse events/ incidence and time to re-operation/ incidence and time to re-vision

    Measured: 24 months

  2. Fusion rate - X-ray

    will be assessed at 3, 6, 12 and 24 months with the following fusion criteria: No evidence of radiolucency surrounding more than 50% of device, translational motion <3 mm and angular motion <5°.

    Measured: 3, 6, 12 and 24 month

  3. Patient Outcomes - Mean EQ-5D

    Measured: 24 months

  4. Modic changes - MRI

    Modic changes will be assessed by MRI

    Measured: 12 and 24 months

  5. Numerical Rating Scale (NRS) for back and leg

    Patients will grade back and leg pain with a numeric scale 0 - 10

    Measured: 3 , 6, 12, and 24 months

  6. Zung self-rating depression scale score

    Patients will complete a questionaire to assess depression.

    Measured: 3, 6, 12, & 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing TM-Ardis Interbody in people with Degenerative Disc Disease, run by Zimmer Biomet at 10 sites in 6 countries.

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 9 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 15 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Canada, Germany, Belgium, France, Spain and 1 more country. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Improvement in ODI score (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Mar 2019.
