About this study
Official title: An Open Label, Single-treatment, Single-period, Single-application, Adhesion Performance Study of Lidocaine Patch 36 mg/Patch (1.8%) in Healthy, Adult, Human Subjects.
The objective of this study is to evaluate the adhesion performance of ZTlido (lidocaine topical system) 1.8% in normal, healthy volunteers.
Read the detailed description
In this open-label, single-treatment, single-period, single-application adhesion performance study, 54 healthy, adult male and female subjects are treated with one lidocaine topical system to their back for 12 hours. Adhesion will be monitored throughout the wear time and skin irritation will be assessed after the topical system is removed.

| Study group | Role | What they receive |
|---|---|---|
| Lidocaine Patch | Experimental | All subjects received one lidocaine topical system, which was applied to a predetermined fixed area on subject's left side of the back or right side of the back (lower/mid back) according to randomization schedule and worn for 12 hours.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Cumulative Adhesion Score
Adhesion of the topical system to the skin is assessed by FDA 0-4 scoring system. The scoring for adhesion of topical systems is indicated as follows: 0 = ≥ 90% Adhered (essentially no lift off the skin), 1 = ≥ 75% to < 90% Adhered (some edges only lifting off the skin), 2 = ≥ 50% to < 75% Adhered (less than half of the patch lifting off the skin), > 0% to < 50% Adhered but not detached (more than half of the patch lifting off the skin without falling off), and 4 = 0% adhered (patched completely detached). The mean cumulative adhesion score is calculated as the sum of scores at each assessment time point divided by the total number of observations.
Measured: 0, 3, 6, 9, 12 hours post-dose
Secondary outcomes (1)
Dermal Response Score
Product tolerability is assessed by Dermal Response Score. The application site is evaluated 30 minutes and 2 hours after product removal (12.5 and 14 hours post-dose, respectively). Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test (i.e., application) site.
Measured: 12.5 and 14 hours post-dose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Lidocaine topical system 1.8% in people with Healthy, run by Scilex Pharmaceuticals, Inc..
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 4 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 18 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 Cumulative Adhesion Score (time frame: 0, 3, 6, 9, 12 hours post-dose). 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 NCT04312750, which also lists 1 linked publication.
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 18 Mar 2020.
