Overview
Brief Summary
This study is being conducted to evaluate the efficacy and safety of 3 different application rates of topically applied Crisaborole ointment 2% over vehicle in adults with mild to moderate atopic dermatitis (AD). In each subject four application areas will be identified. Each subject will receive 4 treatments: the 3 different application rates of the active treatment and the vehicle. The areas will be randomly assigned to treatment with topical Crisaborole ointment 2% and vehicle, once daily, for 2 weeks, without occlusion.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Confirmed diagnosis of active atopic dermatitis (AD) with at least 6 month history prior to screening and that has been clinically stable for 1 month.
- •Has four application areas of 3 cm in diameter with a TSS of ≥5 and TAA of moderate at Day
- •The application areas must not be located on the face, scalp, axillae, groin, genitals, hands, and feet. The application areas should be ≥1 cm apart.
Exclusion Criteria
- •Subject is a female who is breastfeeding, pregnant, or who is planning to become pregnant during the study.
- •Subject has clinically infected AD.
- •Subject has a Fitzpatrick's Skin Phototype ≥
- •Subject is known to have immune deficiency or is immunocompromised.
- •Subject has a history of cancer or lymphoproliferative disease within 5 years prior to Day
- •Subjects with successfully treated nonmetastatic cutaneous squamous cell or basal cell carcinoma and/or successfully treated localized carcinoma in situ of the cervix are not to be excluded.
- •Subject had a major surgery within 8 weeks prior to Day 1 or has a major surgery planned during the study.
- •Subject has any clinically significant medical condition that would, in the opinion of the investigator, put the subject at undue risk or interfere with interpretation of study results.
- •Subject has a known history of chronic infectious disease (eg, hepatitis B, hepatitis C, or infection with human immunodeficiency virus).
- •Subject with a known lack of efficacy to crisaborole.

Outcomes
Primary Outcomes
Total Signs Score (TSS)
Time Frame: Baseline, Day 15
Change from baseline in TSS in target lesions treated with crisaborole ointment 2% or vehicle at Day 15. Total Signs Score (TSS) of the lesion is the assessment of the severity of erythema, edema/papulation, excoriation, and lichenification. Each of these subscales is scored independently using the 4-point severity scale with a value range from 0 to 3; 0 is the minimum (best) and 3 is the maximum (worst). The total score is computed by the sum of each subscale where the total ranges from the minimum 0 (best) to the maximum 12 (worst).
Secondary Outcomes
- Total Signs Score (TSS)(Baseline, Day 8, Day 15)
- Target Area Assessment (TAA)(Change from baseline in TAA at Day 8 and Day 15.)
