A double-blind, single-centered, vehicle-controlled, randomized Phase IIa study of WBI-1001 on patients with mild to moderate Atopic Dermatitis (AD). All body areas were treatable except face, scalp, groin and genital areas. Cream applied BID between 6.00 and 10.00am and 7.00 and 10.00pm daily for 4 weeks. Blood draws for PK analysis were taken weekly at the study centre prior to the morning cream application. Patients returned to the study centre approximately one week later for a follow-up visit.
