Official Title

A Phase 4, Multicenter, Open-label Safety Study Of Crisaborole Ointment 2% In Children Aged 3 Months To Less Than 24 Months With Mild To Moderate Atopic Dermatitis


Approximately 125 subjects will be enrolled. Subjects must have mild-to-moderate AD involving at least 5% treatable %BSA assessed on Baseline/Day 1. Treatable %BSA will be defined as the percent of a subject's total body surface area that is AD-involved, excluding the scalp.

In addition, a cohort of at least 16 of the 125 subjects will be included in a subgroup for PK assessment. These subjects must have moderate AD and a minimum of 35% treatable %BSA, excluding the scalp, and must complete all PK assessments to be included in the PK analysis. Of these subjects, at least 3 subjects who are less than 9 months of age will be enrolled. Subjects discontinuing for reasons other than treatment emergent adverse event ( TEAE) may be replaced at the discretion of the sponsor to ensure 16 subjects complete the PK assessments. Only selected study sites will participate in the PK assessment.

Scheduled study visits/telephone contacts for all subjects will occur at Screening (up to 28 days prior to Baseline/Day 1), Baseline/Day 1, Day 8, Day 15, Day 22, Day 29 (end of treatment/early termination), Day 36, and Day 57 (end of study).
