Dermatitis, Atopic
Conditions
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.
Interventions
Crisaborole ointment 2% (application rate A, B, C) for 15 days (double blind)
Placebo ointment (vehicle)

Intra-individual
Eligibility
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 1. 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 ≥5. * 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 1. 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. * Subject has a known or suspected allergy to crisaborole, including any non-medicinal ingredient, or component of the container. * Subject has a known history of clinically significant drug or alcohol abuse in the last year prior to Day 1.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Signs Score (TSS) | 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
| Measure | Time frame | Description |
|---|---|---|
| Total Signs Score (TSS) | Baseline, Day 8, Day 15 | Change from baseline in lesion severity as measured by TSS at Day 8 and 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). |
