Complete Disease Clearance During LTE: Number of Subjects Achieving Disease Clearance vIGA-AD =0 (Clear) While on Therapy for Subjects Entered LTE vIGA-AD ≥ 1 (Almost Clear )
The vIGA-AD is a clinical tool for assessing the current state/severity of a subject's atopic dermatitis at a given timepoint. It is a static 5-point (0-4) morphological assessment of overall disease severity (scalp excluded), as determined by the investigator, using the clinical characteristics of erythema, induration/papulation, lichenification, oozing/crusting. Higher vIGA-AD scores represents more severe disease.
Baseline to Week 48
Response During LTE: Number of Subjects Achieving vIGA-AD =0 or 1 (Clear or Almost Clear) While on Therapy for Subjects Who Entered LTE With vIGA-AD ≥ 2 (Mild)
The vIGA-AD is a clinical tool for assessing the current state/severity of a subject's atopic dermatitis at a given timepoint. It is a static 5-point (0-4) morphological assessment of overall disease severity (scalp excluded), as determined by the investigator, using the clinical characteristics of erythema, induration/papulation, lichenification, oozing/crusting. Higher vIGA-AD scores represents more severe disease.
Baseline to Week 48
Absolute Change From Baseline in %BSA Affected
Subjects received treatment with tapinarof intermittently guided by disease severity. This outcome measure assesses the change from baseline in %BSA affected in all subjects, including those on and those off therapy. Assessment of BSA with Atopic Dermatitis was estimated by means of the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA. Body regions are assigned specific number of handprints with percentage \[Head and neck = 10% (10 handprints), upper extremities = 20% (20 handprints), Trunk (including axillae and groin) = 30% (30 handprints), lower extremities (including buttocks) = 40% (40 handprints)\]. Lesions on the scalp will not be included in the calculation of %BSA affected. Estimates of the % involvement in 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 48
Mean Change From Baseline in Eczema Area and Severity Index (EASI) Score
Subjects received treatment with tapinarof intermittently guided by disease severity. This outcome measure assesses the change from baseline in EASI score in all subjects, including those on and those off therapy. The EASI scoring system is a clinical tool that quantifies the severity of a subject's AD based on both lesion severity and %BSA affected. The EASI is a composite score ranging from 0 to 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 %BSA involved for each body region relative to the whole body. The subject's scalp is excluded from this assessment. Higher EASI scores indicate more severe disease.

Mean Change in Peak Pruritis-Numeric Rating Scale (PP-NRS) From Baseline
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 or caregiver 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.

Study Arms (1)
tapinarof cream
EXPERIMENTALSubjects entering with vIGA-AD (Validated Investigator Global Assessment of Atopic Dermatitis) ≥1 receive treatment with study drug until they achieve vIGA-AD=0, at which time treatment is discontinued and subjects are monitored for durability of response (remittive response). If/when disease worsening occurs (vIGA-AD ≥2), treatment is re-initiated and continued until vIGA-AD =0 is achieved. Subjects entering with a vIGA-AD=0 discontinue treatment and are monitored for duration of remittive response. If/when disease worsening occurs (vIGA-AD ≥2), treatment is re-initiated and continued until vIGA-AD =0 is achieved. This treatment and re-treatment pattern of use continue until the end of the study.
Interventions
Tapinarof cream, 1%, applied daily to affected areas by subjects or their caregivers based on vIGA-AD. Subjects are advised to choose the application time they prefer and apply the study drug at that approximate time each day of study participation.
