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 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subject has radiographically documented spinal degeneration with instability as documented by the presence of translation >= 4mm or angulation >= 5°.
  • Subject has intractable back pain which does not respond to conservative treatment and in the investigator's opinion, requires surgical spinal fusion.
  • Subject's pain is predominantly associated with the back.
  • Subject has only one level involvement at L3-L4, L4-L5, or L5-S1.
  • Subject is 18 years of age or greater at the time consent is given to participate in the study.
  • Subject is willing to comply with the study plan and sign the informed consent.
  • Subject is male or a non-pregnant, non-nursing female. All females of child-bearing age must agree to use adequate contraception for a period of no less than 16 weeks following surgery.

Who cannot join

  • Subject has primary spinal diagnosis of a disorder other than spinal degeneration with instability at the involved surgical level.
  • Subject has spinal stenosis or condition which requires a full laminectomy procedure.
  • Subject has had a previous fusion, discectomy or laminectomy procedure at L3-L4, L4-L5 or L5-S1.
  • Subject has received drugs which may interfere with bone metabolism within two weeks prior to the planned date of spinal fusion surgery (e.g., steroids, methotrexate) or has a condition which requires postoperative medications that interfere with fusion (e.g., steroids, nonsteroidal antiinflammatory drugs, or methotrexate).
  • Subject has overt or active infection near the operative spinal region.
  • Subject has active systemic infection.
Show all 16Show fewer
  • Subject has history of autoimmune disease (Systemic Lupus Erythematosus or Dermatomyositis).
  • Subject's history includes hypersensitivity to protein pharmaceuticals (monoclonal antibodies or gamma globulins).
  • Subject has received treatment with an investigational therapy within 28 days prior to implantation surgery or such treatment is planned during the 16 weeks following rhBMP-2/BCP implantation.
  • The subject requires electrical bone growth stimulation, allograft, or bone substitute as part of treatment.
  • Subject has history of endocrine or metabolic disorder known to affect osteogenesis (e.g. Paget's disease, renal osteodystrophy, Ehlers Danlos syndrome, or osteogenesis imperfecta).
  • Subject has a known diagnosis of diabetes which requires treatment with medication.
  • Subject has received previous radiation therapy at the site to be fused.
  • Subject is unwilling to return for required follow-up visits.
  • Subject is a prisoner.
  • Subject has insufficient bone mass which precludes surgery (e.g., severe osteopenia or osteoporosis).

What participants receive

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

  • rhBMP-2/BCP deviceDevice

    Also called Recombinant human bone morphogenetic protein-2

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

Study groupRoleWhat they receive
Cohort 1ExperimentalEach patient will receive 15mg of rhBMP-2 in rhBMP-2/BCP device and implant unilaterally during a posterolateral spinal fusion procedure. The contralateral side was fused using standard fusion techniques with autograft bone.
Receives: Device: rhBMP-2/BCP device
Cohort 2ExperimentalEach patient will receive 20mg of rhBMP-2 in rhBMP-2/BCP device and implant bilaterally.
Receives: Device: rhBMP-2/BCP device

What is being measured

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

  1. Fusion Status

    Fusion will be met all of the following criteria:

    1. Evidence of bridging trabecular bone;
    2. Angular motion < 5°;
    3. Translational motion <= 3mm;
    4. No radiolucent lines spanning the entire fusion mass.

    Measured: 12 month

Secondary outcomes (4)
  1. Oswestry Low Back Pain Disability Questionnaire Status

    Measured: 12 month

  2. Neuro/Functional Status

    A neurological functional questionnaire will be completed by patients prior to surgery and postoperative, including three questions pertaining to pain (severity of pain, location of pain, and leg pain side), and four questions associated with functional activities (recreational activity level, putting on shoes and socks, squatting, occupation activity level). Success will be based on a maintenance or improvement from the preoperative condition for the functional components, except that severity of pain success will be based on an improvement of at least one point on the five point scale.

    Measured: 12 month

  3. Neurological Status

    A scale will be used to measure neurological status. This scale focuses on reflexes, sensory, motor function, and the degree of straight leg raise reproducing pain. All of these elements are combined to give an overall score. Success will be based on a maintenance or improvement in all categories from the preoperative condition.

    Measured: 12 month

  4. General Health Status (SF-36)

    Measured: 12 month

Questions about this trial

What is this clinical trial studying?

A study testing rhBMP-2/BCP device 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 7 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 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 Status (time frame: 12 month). 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.
