About this study

Official title: Pivotal IDE Study of the BRYAN(R) Cervical Disc Prosthesis in the Treatment of Degenerative Disc Disease

The purpose of this study is to establish the safety and effectiveness of the BRYAN(R) Cervical Disc Prosthesis in treating single-level degenerative disc disease of the cervical spine.

Read the detailed description

Bryan(R) Cervical Disc Prosthesis is indicated in skeletally mature patients for reconstruction of the disc from C3 to C7 following single level discectomy for intractable radiculopathy and/or myelopathy.

Being tested
ATLANTIS™ Cervical Plate System and allograft, BRYAN Cervical Disc Prosthesis
Keywords
Cervical Disc Replacement, Spondylotic radiculopathy, Spondylotic myelopathy, Myelopathy, Radiculopathy
Medical subject headings
Radiculopathy, Spinal Cord Diseases

What participants receive

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

  • ATLANTIS™ Cervical Plate System and allograftDevice

    Also called cervical plate, plate, fusion, cervical fusion

    Control treatment is commercially available allograft (without bone matrix paste) used in conjunction with the Medtronic Safamor Danek ATLANTIS™ Cervical Plate System.

  • BRYAN Cervical Disc ProsthesisDevice

    Also called disc, cervical disc, artificial disc, BRYAN

    The intent is to treat stable degenerative disc disease by implanting the BRYAN Cervical Disc Prosthesis to provide motion like the normal cervical functional spinal unit.

What is being measured

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

  1. Improvement in patient pain and ability to function

    The self-administered Neck Disability Index patient questionnaire is used to assess patient pain and ability to function. A successful outcome will be declared if: Postoperative Score - Postoperative Score is ≥ 15.

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A study testing ATLANTIS™ Cervical Plate System and allograft and BRYAN Cervical Disc Prosthesis in people with Radiculopathy and Myelopathy, run by Medtronic Spinal and Biologics at 38 sites 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 7 inclusion and 20 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 13 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 38 sites 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?

Improvement in patient pain and ability to function (time frame: 24 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 NCT00437190, 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 13 May 2016.
