What is being measured

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

  1. Number of Participants With Composite Endpoint Success

    The primary endpoint is a composite endpoint. A success is defined as a reduction in overall trunk and limb VAS pain score greater than or equal to 50 percent and no increase in baseline pain medication. VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain.

    Measured: 3 months

Secondary outcomes (9)
  1. Percent Change From Baseline in Leg Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain.

    Measured: 3 months

  2. Percent Change From Baseline in Back Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain.

    Measured: 3 months

  3. Proportion of Subjects With Greater Than or Equal to 80% Reduction From Baseline in Overall Trunk and Limb Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain.

    Measured: 3 months

  4. Proportion of Subjects With Greater Than or Equal to 50% Reduction From Baseline in Back Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain

    Measured: 3 months

  5. Number of Participants With Composite Endpoint Success

    The primary endpoint is a composite endpoint. A success is defined as a reduction in overall trunk and limb VAS pain score greater than or equal to 50 percent and no increase in baseline pain medication. VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain.

    Measured: 12 months

  6. Percent Change From Baseline in Leg Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain

    Measured: 12 months

  7. Percent Change From Baseline in Back Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain

    Measured: 12 months

  8. Proportion of Subjects With Greater Than or Equal to 80% Reduction From Baseline in Overall Trunk and Limb Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain

    Measured: 12 months

  9. Proportion of Subjects With Greater Than or Equal to 50% Reduction From Baseline in Back Pain VAS Score

    VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain

    Measured: 12 months

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?

Yes. Results are posted in the registry (first posted 25 May 2021). 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?

Number of Participants With Composite Endpoint Success (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02924129, which also lists 5 linked publications.

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 Jan 2024.
