Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label, multicenter study to evaluate the systemic exposure and safety of topical tapinarof cream, 1% under conditions of maximal use in pediatric subjects with atopic dermatitis

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a 4-week open-label study in which subjects will be assigned to receive tapinarof cream, 1% once daily for 4 weeks. At the end of the 4-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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 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)

Exclusion Criteria

* 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)
