What participants receive

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

  • LidodermDrug

    Also called Lidocaine patach 5%

    Patients participated in a 2-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.

What is being measured

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

  1. Average daily pain intensity (Brief Pain Inventory [BPI] Questions 3, 4, 5, and 6)

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

Secondary outcomes (7)
  1. Pain quality using the Neuropathic Pain Scale (NPS)

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

  2. Investigator and Patient Global Impression of Change

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

  3. Extent of numbness at the site of pain using the Numbness Questionnaire

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

  4. Patient Global Assessment of Pain Relief

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

  5. Safety assessments included Adverse Events (AE), discontinuation due to AEs, physical and neurological examination results, vital signs, clinical laboratory data, sensory testing, numbness testing, and dermal assessments

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

  6. QoL: Pain interference (BPI Question 9)

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

  7. QoL: Patient Global Assessment of Patch Satisfaction

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

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lidoderm in people with Postherpetic Neuralgia and Diabetic Neuropathy, run by Endo USA Inc., a Keenova Therapeutics Company at 11 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 4 inclusion and 6 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 11 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?

Average daily pain intensity (Brief Pain Inventory [BPI] Questions 3, 4, 5, and 6) (time frame: Visits - V2 (Day 0), V3 (Day 7), V4/EOS (Day 14)). 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.
