An Evaluation of PDI-192 0.1% in Comparison to PDI-192 0.15% in the Treatment of Mild to Moderate Atopic Dermatitis

May 27, 2014 updated by: PreCision Dermatology, Inc.

A Multicenter, Randomized, Double-Blind, Vehicle-Controlled, Parallel Group Evaluation of Twice Daily PDI-192 0.1% in Comparison to PDI-192 0.15% in the Treatment of Mild to Moderate Atopic Dermatitis in Subjects 3 Months to Less Than 18 Years of Age

This study will compare the safety and efficacy of three test article foams (PDI-192 0.1% Foam, PDI-192 0.15% Foam, and Vehicle Foam) such that a final commercial product may be selected for future development.

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

3 months to 17 years (CHILD)

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
"Treatment Success" based on change in Investigator's Global Assessment (IGA)
Time Frame: Baseline and Day 29
Success rate, based on IGA score. Success rate is defined as the percentage of subjects who achieve "Clear" (score = 0) or "Almost Clear" (score = 1) and at least a 2-grade improvement from Baseline on the IGA score at Day 29. IGA is a measure of overall severity of atopic dermatitis using a 5-point ordinal scale from 0 = clear to 4 = severe.
Baseline and Day 29

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
Change in Pruritis Severity at Day 29
Time Frame: Baseline and Day 29
Change from Baseline in the severity of pruritus (itching) at Day 29. Pruritis severity is based on a periodic subject assessment using a 4-point ordinal scale from 0 = none to 3 = severe.
Baseline and Day 29

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Eczema Area and Severity Index (EASI) Score
Time Frame: Baseline and Day 29
Percent change from Baseline in EASI scores at Day 29. EASI excludes non-key signs of eczema (such as xerosis and scaling, oozing and crusting), and subjective parameters (such as pruritus and sleep loss) in order to focus the index on key disease signs and to avoid mixing objective parameters with subjective symptoms. EASI scores range from 0 (least severe) to 72 (most severe).
Baseline and Day 29
Change in Body Surface Area (BSA) Affected
Time Frame: Baseline, Days 8, 15 and 29
Percent change from Baseline in the percent BSA affected by disease at Days 8, 15 and 29.
Baseline, Days 8, 15 and 29
Change in Clinical Signs of Atopic Dermatitis (AD)
Time Frame: Baseline and Days 8, 15 and 29
Change from Baseline in severity of erythema, induration/papulation, excoriation, lichenification and oozing/crusting at Days 8, 15, and 29. All clinical signs are evaluated on a 4-point ordinal scale from 0 (none) to 3 (severe).
Baseline and Days 8, 15 and 29
Change in Pruritis Severity at Days 8 and 15
Time Frame: Baseline and Days 8 and 15
Change from Baseline in the severity of pruritus (itching) at Days 8 and 15. Pruritis severity is based on a periodic subject assessment using a 4-point ordinal scale from 0 = none to 3 = severe.
Baseline and Days 8 and 15
Subject Assessment of Improvement in Atopic Dermatitis
Time Frame: Day 29
Subject global assessment of improvement in AD at Day 29, based on a 5-point ordinal scale from 1 (excellent improvement) to 5 (worse).
Day 29
