About this study

Official title: Phase I/II, Multicenter, Open-label, Single Administration, Dose Finding, Clinical Trial to Evaluate the Safety and Tolerability of Intradiscal rhGDF-5 for the Treatment of Early Stage Lumbar Disc Degeneration

Study to show the effectiveness and safety of a single injection of rhGDF5 into a degenerating single spinal disc in treating lumbar level degenerative disc disease

Being tested
Intradiscal rhGDF-5
Medical subject headings
Intervertebral Disc Degeneration

What participants receive

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

  • Intradiscal rhGDF-5Drug

    The API is recombinant human growth and differentiation factor-5 (rhGDF-5), a recombinant version of human GDF-5. GDF-5 is a member of the transforming growth factor-b (TGF-b) superfamily and the bone morphogenetic protein (BMP) subfamily, and is known to influence the growth and differentiation of various tissues, including the intervertebral disc. In vitro experiments have shown that rhGDF-5 can stimulate gene expression and synthesis of the extracellular matrix proteins type II collagen and aggrecan. In vivo experiments in rabbit models of disc degeneration have shown that intradiscal injections of rhGDF-5 can stimulate an increase in disc height and hydration.

What is being measured

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

  1. Neurological Assessment for Motor Function and Reflexes/Sensory

    Neurological Assessment for Motor Function and Reflexes/Sensory- Number of patients with Clinically Significant Abnormal results at 12 months.

    For Motor Function, Clinically Significant Abnormal results are determined by the surgeon investigator and are further classified by grade: 0= No Movement, 1= Flicker/trace of contraction, 2=Active movement when gravity removed, 3= Active movement against gravity, 4= Active Movement against gravity and resistance.

    For Reflexes/Sensory, Clinically Significant Abnormal results are determined by the surgeon investigator and are based on exams of the Knee, Ankle, L3-L5 Dermatone, and S1 Dermatome. Tension signs are evaluated with a straight leg raise to determine at which point, if any, sciatic pain occurs.

    Measured: 12 months

  2. Treatment Emergent Adverse Events- Relationship to Study Drug

    Number of patients with Treatment Emergent Adverse Events that were designated as related or possibly related to Study Drug.

    Measured: Through a 12 month period and annual telephone contact at 24 and 36 months for subject health status follow-up

Secondary outcomes (4)
  1. Change in Function Assessed by Oswestry Disability Index Change at 12 Months From Baseline

    The Oswestry Disability Index (ODI) is a 10-category (Pain Intensity, Personal Care, Lifting, Walking, Sitting, Standing, Sleeping, Sex Life, Social Life, Traveling) disability measurement scale with a graded response from 0 to 5, with 0 being the best score (no impairment) to 5 being the worst score (significant impairment). ODI score for a subject is calculated by adding the scores and converting the score to a 100 point scale.

    Measured: 12 months

  2. Change in Pain Visual Analog Scale (VAS) at 12 Months From Baseline

    The Visual Analog Scale (VAS) pain score asks the subject to place a vertical mark on a horizontal line (that is approximately 10 cm long) with 'No Pain' (score of 0 = 0 cm) listed on the left and 'Very severe pain' (score of 10=10cm) labeled on the right. The subject is instructed to indicate the amount of pain they feel in their back.

    Measured: 12 months

  3. Change in Physical Component Summary of Quality of Life Measure Assessed by Short-Form 36 at 12 Months From Baseline

    The 36-item Short Form Health Survey (SF-36) is a patient reported outcome survey that evaluates functional health and well-being. The survey is converted into two summary measures (the Physical Component - PCS and Mental Component- MCS) that are scored from 0 to 100 (where 100 indicates the highest level of health).

    Measured: 12 Months

  4. Change in Mental Component Summary Quality of Life Measure Assessed by Short Form SF-36 at 12 Months From Baseline

    The 36-item Short Form Health Survey (SF-36) is a patient reported outcome survey that evaluates functional health and well-being. The survey is converted into two summary measures (the Physical Component - PCS and Mental Component- MCS) that are scored from 0 to 100 (where 100 indicates the highest level of health).

    Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Intradiscal rhGDF-5 in people with Degenerative Disc Disease, run by DePuy Spine at 8 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 3 inclusion and 5 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 26 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 27 Jan 2016). 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?

Neurological Assessment for Motor Function and Reflexes/Sensory (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 26 Feb 2016.
