About this study

Official title: A Pilot Study of Recombinant Human Bone Morphogenetic Protein-2 and Biphasic Calcium Phosphate With or Without the TSRH® Spinal System for Posterolateral Lumbar Fusion in Patients With Symptomatic Degenerative Disc Disease

The purpose of this pilot clinical trial is to evaluate both device designs (rhBMP-2/BCP and rhBMP-2/BCP/TSRH® spinal System) as methods of facilitating spinal fusion as compared to instrumented fusion with autograft in patients with symptomatic degenerative disc disease.

Being tested

What participants receive

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

  • rhBMP-2/BCPProcedure or surgery

    Also called recombinant human Bone Morphogenetic Protein-2, biphasic calcium phosphate

    The rhBMP-2/BCP device component consists of recombinant human Bone Morphogenetic Protein-2 ( rhBMP-2) and the biphasic calcium phosphate (BCP) carrier.

  • rhBMP-2/BCP/TSRH® Spinal SystemDevice

    Also called recombinant human Bone Morphogenetic Protein-2, biphasic calcium phosphate

    rhBMP-2/BCP device will be used in conjunction with the posterior spinal fixation system, the TSRH® Spinal System.

  • Autograft/TSRH® Spinal SystemDevice

    Also called Autograft

    The control device will be autogenous bone from the iliac crest of the patient used in conjunction with the TSRH® spinal System.

What is being measured

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

  1. Fusion

    Fusion is defined as:

    1. Evidence of bridging trabecular bone.
    2. No evidence of motion as defined by: a. No more than 3mm difference in translation on the lateral flexion/extension radiographs determined by superimposing the two views, one upon the other; b. Less than 5° difference in angular motion between flexion and extension as seen on the lateral flexion/extension radiographs;
    3. Absence of radiolucent lines completely through the fusion mass.

    Measured: 24 month

  2. Pain/Disability Status

    The self-administered Oswestry Low Back pain Disability Questionnaire will be used. Success for each individual patient will be defined as pain/disability improvement postoperatively according to the following definition: Preoperative Score - Postoperative Score >= 15

    Measured: 24 month

Secondary outcomes (7)
  1. Neurological Status Success

    Neurological status will be assessed preoperatively and postoperatively using a comprehensive neurological status scale. Neurological status is based on four types of measurements (sections): motor, sensory, reflexes and straight leg raise.

    Measured: 24 month

  2. Hip (Donor Site) Pain

    Measured: 24 month

  3. General Health Status (SF-36)

    Measured: 24 month

  4. Pain Status (back pain, leg pain)

    Measured: 24 month

  5. Patient Satisfaction

    Measured: 24 month

  6. Patient Global Perceived Effect

    Measured: 24 month

  7. Overall Success

    Measured: 24 month

Questions about this trial

What is this clinical trial studying?

A study testing rhBMP-2/BCP, rhBMP-2/BCP/TSRH® Spinal System and Autograft/TSRH® Spinal System in people with Degenerative Disc Disease, run by Medtronic Spinal and Biologics.

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 14 inclusion and 22 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 17 May 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Fusion (time frame: 24 month). 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 17 May 2023.
