Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 70 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • The patient qualifies for ACDF based upon physical examination and medical history. The patient has single or two adjacent levels(s) symptomatic cervical disc disease (including disc herniation and/or spondylosis) from the C3-C4 disc to the C7-T1 disc with associated radiculopathy and/or myelopathy due to nerve root and/or spinal cord compression due to herniated nucleus pulposus or osteophyte formation on the posterior vertebral endplates.

Who cannot join

  • The patient is mentally compromised (e.g., under treatment for a psychiatric disorder or has senile dementia or Alzheimer's disease), or has evidence of alcohol or other substance abuse for the previous 12 months.
  • The patient has a neuromuscular disorder that would engender unacceptable risk of instability, implant fixation failure, or complications in postoperative care.
  • The patient has a diagnosed systemic disease that requires the chronic administration of nonsteroidal anti-inflammatory and steroidal drugs.
  • The patient has osteopenia to a degree that would contraindicate spinal instrumentation (borderline osteoporosis).
  • The patient has osteoporosis to a degree that would contraindicate spinal instrumentation.
  • The patient is unable or unwilling to attend postoperative follow-up visits.
Show all 13Show fewer
  • The patient has received an investigational drug within the previous six months or an investigational device within the previous 12 months.
  • The patient has a spinal condition other than Cervical DDD based upon physical examination and medical history.
  • The patient has an infection site distant from the involved levels that may spread to the involved levels hematogenously.
  • The patient has insufficient bone stock to fix the component.
  • The patient has a known sensitivity to metallic implants.
  • The patient is a prisoner.

About this study

The objective of this clinical investigation is to compare patients treated with Anterior Cervical Discectomy and Fusion (ACDF) using the Hedrocel Cervical Fusion Device, with a concurrent, randomized, control group receiving autologous iliac crest bone graft or allograft and test the hypothesis that ACDF with Hedrocel is non-inferior to ACDF with allograft or autologous bone graft.

Read the detailed description

The objective of this clinical investigation is to compare patients treated with Anterior Cervical Discectomy and Fusion (ACDF) using the Hedrocel Cervical Fusion Device, with a concurrent, randomized, control group receiving autologous iliac crest bone graft. Success criteria include radiographic evidence of fusion, and improvement in pain, function and overall quality of life. If shown to be successful, the use of the Hedrocel Cervical Fusion Device would eliminate complications associated with harvesting autologous bone graft and provide an alternative for those who are unable to provide autologous bone graft from the iliac crest.

What is being measured

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

  1. Overall Clinical Success (NDI, Fusion, Additional Surgical Procedures)

    Success was defined as an improvement in patient functional capability using the Neck Disability Index (NDI) by at least 10% as compared to the pre-operative evaluation and Radiographic evidence of fusion (< 3mm translation; < 5° angular motion and absence of radiolucent lines around ≥ 50% of the device)and A comparison of the incidence of intraoperative and postoperative complications which resulted in additional surgical procedures of revision, removal or supplemental fixation at 12 months

    Measured: 12 Months

  2. Neck Disability Index (NDI)

    The Neck Disability Index (NDI) is an instrument used for testing self-rated disability in neck pain patients. The Neck Disability Index (NDI) consists of 10 questions, each with a score up to 5, for a total score of 50. The lower the score, the less self-rated disability.

    NDI scoring:

    • 0 - 4 = No disability
    • 5 - 14 = Mild disability
    • 15 - 24 = Moderate disability
    • 25 - 34 = Severe disability
    • 35 or over = Complete disability

    Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Anterior Cervical Discectomy and Fusion in people with Symptomatic Cervical Disc Disease, run by Zimmer Biomet at 13 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 5 inclusion and 13 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 23 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 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.

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?

Yes. Results are posted in the registry (first posted 12 Aug 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Overall Clinical Success (NDI, Fusion, Additional Surgical Procedures) (time frame: 12 Months). The study lists 2 primary outcomes in all. 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 23 Aug 2013.
