Detailed Description
This study is a 8-week double-blind, vehicle-controlled treatment study in which subjects will be randomized to receive tapinarof cream, 1% or vehicle cream once daily for 8 weeks.
At the end of the 8-week study treatment, qualified subjects will have the option to enroll in an open-label, long-term extension study for an additional 48 weeks of treatment.
Subjects who do not participate in the open-label, long-term extension study will complete a follow-up visit approximately one week after the end of treatment in this study.

- History of or ongoing serious illness or medical, physical, or psychiatric condition(s) that, in the Investigator's opinion, may interfere with the subject's participation in the study, interpretation of results, or ability to understand and give informed consent.
- Pregnant or lactating females
- History of sensitivity to the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the Investigator or Medical Monitor, contraindicates their participation

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent of subjects who have a validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) score of clear or almost clear (0 or 1) with a Minimum 2-grade Improvement from Baseline to Week 8. Analyses were done using Multiple Imputation.
Time Frame: Baseline to Week 8
|
The vIGA-AD is a global assessment of the current state of the disease.
It is a static 5-point scale used to grade overall disease severity (scalp excluded), as determined by the investigator, using the clinical characteristics of erythema, induration/papulation, lichenification, oozing/crusting.
The vIGA-AD ranges from 0 to 4 and is calculated as Clear (0), Almost clear (1), Mild (2), Moderate (3), and Severe (4).
Higher vIGA-AD scores represent more severe disease.
|
Baseline to Week 8
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent of subjects with ≥ 75% improvement in Eczema Area and Severity Index (EASI) from Baseline to Week 8. Analyses were done using Multiple Imputation.
Time Frame: Baseline to Week 8
|
The Eczema Area and Severity Index (EASI) is a scoring system that takes into account the overall severity of disease based on lesion severity and the extent of percent body surface area affected with atopic dermatitis.
The EASI is a composite score ranging from 0 -72 that takes into account the degree of erythema, edema/papulation, excoriation, and lichenification (each scored from 0 to 3 separately) for each of four body regions, with adjustment for the percent body surface area involved for each body region relative to the whole body.
A higher EASI score represents more severe disease.
|
Baseline to Week 8
|
Mean change in in Percent of Total Body Surface Area (%BSA) affected from Baseline to Week 8.
Time Frame: Baseline to Week 8
|
Assessment of percent body surface area (%BSA) is an estimate of the percentage of total involved skin with atopic dermatitis.
Estimates were made using the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumbs together) represented approximately 1% of the total BSA.
Body regions are assigned a specific number of handprints with associated percentages (Head and neck = 10% [10 handprints], upper extremities = 20% [20 handprints], trunk (including axillae and groin) = 30% [30 handprints], lower extremities, including buttocks, = 40% [40 handprints]).
Estimates of the percent involvement of each body region will be multiplied by the fraction of total body area to obtain the total %BSA involved by region and overall.
|
Baseline to Week 8
|
Percent of subjects with ≥ 90% improvement in Eczema Area and Severity Index (EASI) from Baseline to Week 8. Analyses were done using Multiple Imputation.
Time Frame: Baseline to Week 8
|
The Eczema Area and Severity Index (EASI) is a scoring system that takes into account the overall severity of disease based on lesion severity and the extent of percent body surface area affected with atopic dermatitis.
The EASI is a composite score ranging from 0 -72 that takes into account the degree of erythema, edema/papulation, excoriation, and lichenification (each scored from 0 to 3 separately) for each of four body regions, with adjustment for the percent body surface area involved for each body region relative to the whole body.
A higher EASI score represents more severe disease.
|
Baseline to Week 8
|
Percent of subjects ≥ 12 years old with a Baseline Peak Pruritis-Numeric Rating Scale (PP-NRS) score ≥ 4 who achieve ≥ 4-point reduction in the average weekly PP-NRS from Baseline to Week 8.
Time Frame: Baseline to Week 8
|
The Peak Pruritus Numeric Rating Scale (PP-NRS) is used to quickly assess itch/pruritus severity over a 24-hour period.
The PP-NRS is scored on a scale of 0 to 10, with 0 being "no itch" and 10 being "worst itch imaginable".
The subject will utilize the scale to assess peak pruritis once per day and record the results in their diaries.
The daily ratings are averaged to generate a score for the week.
