About this study

Official title: A Single-Blinded, Randomized Controlled Trial of Regenexx™ PL-Disc Versus Steroid Epidurals for Treatment of Lumbar Radiculopathy

The primary objective of this study is to compare the improvement in subject-reported clinical outcomes for Regenexx PL-Disc vs. steroid epidural for treatment of lumbar radiculopathy, from baseline to 3 months, with continued evaluation of efficacy and durability up to 12 months.

Secondary objectives include incidence of post-operative complications, adverse events, re-injections, and surgical intervention; change in pain score and use of pain medications.

Read the detailed description

Prospective, single-blinded, randomized, controlled to include 25 subjects treated with Regenexx PL-Disc and 25 subjects treated with steroid epidural injection with the steroid epidural group crossing over to the PL-Disc injection group at 3 months.

Subjects will have symptoms consistent with lumbar radiculopathy confirmed by physical examination.

Subjects will be enrolled within 60 days prior to injection and take part in follow-up visits for one year following treatment. A preoperative visit will occur at the time of enrollment; follow-up visits will occur at the clinical site at 6 weeks, 3 months, 6 months and 12 months post injection. Subjects will remain blinded to the treatment allocation through at least the 3 month primary endpoint. Control subjects not improving after the 3 month visit will be unblinded and given the opportunity to cross-over to the PL-Disc group.

Subjects will complete the study following the 1 year follow-up visit.

What participants receive

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

  • Regenexx PL-DiscProcedure or surgery

    Injection into the epidural space under image guidance of autologous, concentrated peripheral blood based platelet mix combined with a nanogram dose of corticosteroid.

  • Steroid EpiduralProcedure or surgery

    Injection into the epidural space under image guidance of 3 mg of betamethasone.

What is being measured

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

  1. Oswestry Disability Index Change from Baseline

    The primary endpoint for this study is the difference between treatment groups in the within patient mean change from baseline to 3 months in Oswestry Disability Index (ODI) scores.

    Measured: Change from baseline to 3 months

Secondary outcomes (8)
  1. Mean Functional Rating Index Scores

    Difference between treatment groups in mean Functional Rating Index (FRI) scores at each follow-up timepoint.

    Measured: 6 weeks, 3 months, 6 months, 12 months

  2. Mean ODI scores

    Difference between treatment groups in mean ODI scores at each follow-up timepoint

    Measured: 6 weeks, 3 months, 6 months, 12 months

  3. Mean Pain Scales

    Difference between treatment groups in mean 0-10 pain scales at each follow-up timepoint

    Measured: 6 weeks, 3 months, 6 months, 12 months

  4. Incidence of Complications and Adverse Events

    Incidence of post-operative complications and adverse events between treatment groups.

    Measured: 12 months

  5. Incidence of re-injection/re-operation

    Incidence of re-injection and surgical operation between treatment groups.

    Measured: 12 months

  6. Use of pain medications

    Difference between treatment groups in use of pain medications at each follow-up timepoint

    Measured: 6 weeks, 3 months, 6 months, 12 months

  7. Time to Resolution of Complications and Adverse Events

    Time to resolution of post-operative complications and adverse events between treatment groups.

    Measured: 12 months

  8. Time to re-injection/re-operation

    Time to re-injection and surgical operation between treatment groups.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Regenexx PL-Disc and Steroid Epidural in people with Radiculopathy and Herniated Disc, run by Regenexx, LLC 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 5 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: stopped early, as of the sponsor's last update on 3 Jun 2016. 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 was stopped early (reason given: Difficulties in recruitment). Results are not available in the source record.

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?

Oswestry Disability Index Change from Baseline (time frame: Change from baseline to 3 months). 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 3 Jun 2016.
