Key Clinical Point: Crisaborole induces proteomic changes and modulates the lesional skin phenotype toward normal skin in mild-to-moderate atopic dermatitis (AD).
Major finding: At days 8 and 15, a markedly greater number of biomarkers were down-regulated with crisaborole vs vehicle (123 vs 9 and 162 vs 22, respectively), with a significantly higher rate of improvement in the overall lesional (45.9% vs 12.6% and 57.0% vs 28.3%, respectively; both P < .001) and nonlesional (53.0% vs 15.5% and 62.6% vs 36.8%, respectively; both P < .001) proteomes relative to a normal skin proteome.
Study details: This phase 2a study conducted a proteomic analysis in 20 control individuals and 40 adult patients with mild-to-moderate AD after double-blind, 1:1 random assignment of two target lesions in each patient with AD to crisaborole (2% ointment) or vehicle twice daily for 14 days.
Disclosures: This study was funded by Pfizer, New York. Some authors reported ties with various organizations, including Pfizer. One author declared being an employee of and holding shares in Pfizer.
