About this study

Official title: Prospective Randomized Clinical Trial Comparing PEEK and Allograft Spacers in Patients Undergoing Spinal Intervertebral Fusion Surgeries

Being tested
Posterior/Transforaminal Lumbar Interbody Fusion (P/TLIF), Anterior Cervical Discectomy and Fusion (ACDF)

What participants receive

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

  • Posterior/Transforaminal Lumbar Interbody Fusion (P/TLIF), Anterior Cervical Discectomy and Fusion (ACDF)Procedure or surgery

    Lumbar or cervical fusion

Study groups in NCT01406405
Study groupRoleWhat they receive
PEEK cagesPatients will have fusion surgery performed using polyetheretherketone (PEEK) cages
Receives: Procedure: Posterior/Transforaminal Lumbar Interbody Fusion (P/TLIF), Anterior Cervical Discectomy and Fusion (ACDF)
Allograft spacersPatients will have fusion surgery performed using allograft spacers
Receives: Procedure: Posterior/Transforaminal Lumbar Interbody Fusion (P/TLIF), Anterior Cervical Discectomy and Fusion (ACDF)

What is being measured

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

  1. Pain Intensity Scores

    Improvement in the Neck/Arm or Low Back/Leg Visual Analog pain Scale (VAS) scores. A 30% reduction in pain intensity will be considered to be a successful response to treatment.

    Measured: 24 (+/- 2) months

Secondary outcomes (1)
  1. Clinical and Radiographic Outcomes

    • Assessment of Neck or Lower Back Disability Scores
    • Assessment of SF-36 Health Survey
    • Assessment of restoration of vertebral height, sagittal alignment, and graft subsidence
    • Assessment of fusion rates

    Measured: 3 (+/-2) weeks and 24 (+/- 2) months

Questions about this trial

What is this clinical trial studying?

An observational study of Degenerative Disc Disease, run by Justin Parker Neurological Institute 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 10 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 27 Feb 2019. 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?

Pain Intensity Scores (time frame: 24 (+/- 2) 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 NCT01406405, which also lists 1 linked publication.

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 27 Feb 2019.
