About this study

Official title: Open-Label Study Assessing the Efficacy of Topical Lidocaine Patch in Treatment of Low Back Pain

Patients with acute or chronic Lower Back Pain (LBP) participated in a Phase IV clinical trial to assess the effectiveness of Lidoderm administered once daily (q24h) for 2 weeks in the treatment of acute and chronic LBP.

Being tested
Lidoderm®

What participants receive

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

  • Lidoderm®Drug

    Also called Lidocaine patch 5%

    Patients participated in a 6-week treatment period. Commercially available Lidoderm (lidocaine patch 5%) was provided to patients with up to four patches applied topically once daily (q24h) to the area of maximal peripheral pain. Patients were stratified into the following groups at enrollment: acute (<6 weeks) LBP, subacute (6 weeks to <3 months) LBP, short-term chronic (3 months to 12 months, inclusive) LBP, and long-term chronic (>12 months LBP)

What is being measured

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

  1. Mean change in average daily intensity (Question 5 of Brief Pain Inventory [BPI] Questionnaire) from baseline to Week 2

    Measured: Visits - V2 (Day 0), V3 (Day 7), V4 (Day 14), V5 (Day 28), V6/EOS (Day 42)

Secondary outcomes (4)
  1. Mean change from baseline to Week 6 in average pain intensity (Question 5 of the BPI)

    Measured: Visits - V2 (Day 0), V3 (Day 7), V4 (Day 14), V5 (Day 28), V6/EOS (Day 42)

  2. Mean change from baseline to Week 2 and to Week 6 in Neuropathic Pain Scale (NPS) composite scores

    Measured: Visits - V2 (Day 0), V3 (Day 7), V4 (Day 14), V5 (Day 28), V6/EOS (Day 42)

  3. QOL: change from baseline to Week 2 to Week 6 in Question 9 of the BPI, in Beck Depression Inventory Questionnaire, and the Patient and Investigator Global Assessment of Patch Satisfaction and Pain Relief

    Measured: Visits - V2 (Day 0), V3 (Day 7), V4 (Day 14), V5 (Day 28), V6/EOS (Day 42)

  4. Safety assessments include AEs, clinical laboratory tests, vital signs, physical/neurological examinations, and dermal/sensory assessments.

    Measured: Visits - V2 (Day 0), V3 (Day 7), V4 (Day 14), V5 (Day 28), V6/EOS (Day 42)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lidoderm® in people with Acute and Chronic Non-radicular LBP, run by Endo USA Inc., a Keenova Therapeutics Company at 7 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 10 inclusion and 11 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 2 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 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 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?

Mean change in average daily intensity (Question 5 of Brief Pain Inventory [BPI] Questionnaire) from baseline to Week 2 (time frame: Visits - V2 (Day 0), V3 (Day 7), V4 (Day 14), V5 (Day 28), V6/EOS (Day 42)). 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 2 Jan 2024.
