About this study

Official title: NSAIDs in Sciatica (NIS), an Investigator Initiated Randomised Placebo Controlled Trial of Naproxen

This study will evaluate whether treatment with Naproxen 500 mg twice daily is superior to placebo for the improvement of leg pain in patients with sciatica. Half of patients will receive Naproxen while the other half will receive placebo.

Read the detailed description

Sciatica is an established term for pain radiating from the lower back or buttock into the leg, commonly caused by a disc herniation. Given their analgesic and anti-inflammatory mechanisms of action, NSAIDs (Non-steroidal anti-inflammatory drugs) have been, and are still being regarded as standard therapy for sciatica.

However, very few randomised controlled trials of NSAIDs have been undertaken in sciatica, and no study has showed clinically meaningful effects as compared to placebo.

Since NSAIDs involve the risk of serious gastrointestinal, vascular and renal side effects there is a strong need to clarify their potential beneficial effects in sciatica.

What is being measured

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

  1. Leg pain

    A 0-10 numeric rating scale of average leg pain intensity in the previous 24 hours

    Measured: Daily from baseline to day10

Secondary outcomes (8)
  1. Back pain

    24 h average back pain will be assessed by a 0-10 numeric rating scale

    Measured: Daily from baseline to day10

  2. Disability

    Roland Morris Disability Questionnaire modified for use in sciatica

    Measured: Day 0, day 5, day, day 10, day 12

  3. Sciatica symptoms

    Sciatica Bothersomeness Index

    Measured: Day 0, day 5, day, day 10, day 12

  4. Work

    Ability to work and study as normal

    Measured: Day 0, day 10, day 12

  5. Improvement

    Global perceived change of sciatica/back problem on a verbal rating scale (Completely gone, much better, better, a little better, no change, a little worse, worse and much worse).

    Measured: Day 5, day 10

  6. Rescue medication

    Intake of Paracetamol 500 mg tablets (rescue medication) for pain

    Measured: Daily from day1 to day10

  7. Opioid medication

    Intake of opioid medication (weak or strong) for pain

    Measured: Daily from day1 to day10

  8. Responder

    >30% and >50% reduction in leg pain relative to baseline

    Measured: Day 5, day 10

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Naproxen 500 Mg in people with Sciatica, run by Ostfold Hospital Trust at 4 sites in Norway.

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 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 5 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Norway. 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. Some participants in this study may receive a placebo. 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?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Leg pain (time frame: Daily from baseline to day10). 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 NCT03347929, which also lists 2 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 5 Oct 2023.
