About this study

Official title: A Pilot Trial Evaluating the Feasibility of Using Platelet-Rich Plasma (PRP) for Treatment of Symptomatic Osteoarthritis of the Lumbar Facet Joint(s) of the Spine

The purpose of this study is to investigate the feasibility of standardized autologous platelet rich plasma injections into osteoarthritic lumbar facet joints to treat back pain and improve patient function.

Being tested
Autologous platelet rich plasma

What participants receive

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

  • Autologous platelet rich plasmaBiological

    0.5 mL autologous platelet rich plasma into a symptomatic osteoarthritic lumbar facet to treat back pain caused by lumbar facet syndrome

Study groups in NCT04522674
Study groupRoleWhat they receive
Autologous platelet rich plasmaExperimental0.5 mL of activated autologous PRP will be injected by fluoroscopic guidance into the affected lumbar facet joint (s) depending on the number of affected levels. A max of 4 joints will be injected per patient.
Receives: Biological: Autologous platelet rich plasma

What is being measured

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

  1. Change in pain Visual Analog Score with back flexion and at rest from baseline after intervention over time.

    Pain as assessed from 0-10. Where 10 is severe pain and 0 is no pain. Improvement of pain by 50% after intervention is defined as treatment success

    Measured: Baseline, immediately after intervention, 1 week, 1 month, and 3 months post intervention

  2. PROMIS Survey for Low Back Pain Function (PROMIS-29)

    NIH validated PROMIS score for physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social activities, pain interference, and pain intensity (PROMIS- 29 Profile v2.0). A higher PROMIS T-score represents more of the concept being measured.For negatively-worded concepts like Anxiety,a T-score of 60 is one SD worse than average.By comparison,an Anxiety T-score of 40 is one SD better than average.However,for positively-worded concepts like Physical Function-Mobility,a T-score of 60 is one SD better than average while a T-score of 40 is one SD worse than average.

    Measured: Baseline, immediately after intervention, 1 week, 1 month, and 3 months post intervention

Secondary outcomes (3)
  1. Length of enrollment of 10 patients and attrition rate

    Determine percentage of patients who enroll in the study, how long it takes to enroll 10 patients, and attrition rate of patients in a 3 month time period

    Measured: 3 months

  2. Safety as measured by number of subjects with at least one adverse event

    Monitoring of adverse events such as bleeding, infection, allergy, neurologic deficits, and injection-related complications.

    Measured: 3 months

  3. Degree of improvement in pain and function based on severity of lumbar facet OA.

    Using the surveys from the primary outcome, the investigators plan to perform a subgroup analysis depending on the severity of lumbar facet OA as seen by imaging

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Autologous platelet rich plasma in people with Platelet-Rich Plasma, run by University of Colorado, Denver 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 12 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 4 May 2022. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Change in pain Visual Analog Score with back flexion and at rest from baseline after intervention over time. (time frame: Baseline, immediately after intervention, 1 week, 1 month, and 3 months post intervention). 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 4 May 2022.
