Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Cumulative Adhesion Score
Time Frame: 0, 3, 6, 9, 12 hours post-dose
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.
0, 3, 6, 9, 12 hours post-dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Dermal Response Score
Time Frame: 12.5 and 14 hours post-dose
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.
12.5 and 14 hours post-dose

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
