Baseline to Day 28
Tapinarof Plasma PK Parameters on Day 1: AUC0-τ
The AUC in plasma is a pharmacokinetic parameter that describes the overall exposure of the drug.

Tapinarof Plasma PK Parameters on Day 1: Cmax
The Cmax is a pharmacokinetic parameter that describes the highest concentration of the drug that is achieved after dosing.
Day 1 (PK samples collected pre-dose and at 1, 3, and 5 hours post-dose)
Tapinarof Plasma PK Parameters on Day 1: Tmax

Eligibility Criteria
You may qualify if:
- Male and female subjects age 2 to 17 with a confirmed clinical diagnosis of atopic dermatitis and present for at least 6 months for ages 6-17 years old, 3 months for ages 2-5 years old
- BSA involvement ≥ 25% for subjects ages 12-17 years old, or ≥ 35% for subjects ages 2-11 years old, suitable for topical therapy.
- vIGA-AD score of ≥ 3 at screening and baseline (pre-dose)
- Female subjects of child bearing potential who are engaging in sexual activity that could lead to pregnancy agree to follow the specified contraceptive guidance throughout the study
- Capable of giving written informed consent
- Negative pregnancy test at Baseline (Day 1)
You may not qualify if:
- Immunocompromised at screening
- Chronic or acute systemic or superficial infection requiring treatment with systemic antibacterials or antifungals within one week prior to baseline visit
- Significant dermatological or inflammatory condition other than AD that, in the Investigator's opinion, would make it difficult to interpret data or assessments during the study
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥2.0x the upper limit of normal (ULN).
- Screening total bilirubin \> 1.5x ULN
- Current or chronic history of liver disease
- Current or history of cancer within 5 years except for adequately treated cutaneous basal cell carcinoma, squamous cell carcinoma or carcinoma in situ of the cervix
- Subjects who would not be considered suitable for topical therapy
- Use of any prohibited medication or procedure within the indicated period before the baseline visit including other investigational product within 30 days or 5 half-lives of the investigational product (whichever is longer)
- 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
- Previous known participation in a clinical study with tapinarof (previously known as GSK2894512 and WBI-1001)
