Abstract | BACKGROUND: METHODS: In this multicenter, randomized, double-blind, dose-ranging, phase 2 study, adolescent patients 12 to 17 years of age with mild to moderate AD and 2 distinct target AD lesions were randomized to once-daily (QD) or twice-daily (BID) treatment with crisaborole topical ointment. For each patient, 2 target lesions were randomized to receive 29 days of treatment with 0.5% or 2% crisaborole topical ointment. The primary endpoint was change from baseline in AD severity index (ADSI) score for each lesion. Exploratory efficacy endpoints and safety were also assessed. RESULTS: A total of 86 patients were enrolled and received crisaborole topical ointment 0.5% or 2% QD (n=44) or BID (n=42). All dosing regimens produced dose-related improvements in ADSI as well as in all 5 component signs and symptoms of AD ( erythema, excoriation, exudation, lichenification, and pruritus). The greatest improvements were consistently observed with crisaborole topical ointment, 2% applied BID. With this regimen, ADSI improved from baseline by 71%, and total or partial clearance of target lesions (ADSI ≤ 2) was achieved by 62% of patients after 29 days of treatment. Both doses of crisaborole topical ointment were well tolerated; mild application site reactions were the only treatment-related adverse events (QD, n=3; BID, n=1). CONCLUSION: These results provide preliminary evidence of the efficacy and safety of crisaborole topical ointment, 2% applied topically BID in adolescents with mild to moderate AD.
