This study was designed to further increase the understanding of the pharmacokinetics of
tacrolimus in the affected skin of atopic dermatitis patients following repeated topical
application of tacrolimus ointment 0. 1%.
Official title: A Study to Determine the Distribution of Tacrolimus in the Skin and the Systemic Pharmacokinetics of Tacrolimus in Adult Patients With Moderate to Severe Atopic Dermatitis Following First and Repeated Application of the Tacrolimus Ointment.
Study design: Treatment, Open Label, Uncontrolled, Single Group Assignment, Pharmacokinetics Study
Primary outcome: Distribution of tacrolimus in the skin after first and repeated application of tacrolimus ointment in adult patients with moderate to severe atopic dermatitis.
Secondary outcome: Systemic pharmacokinetics of tacrolimus after first and repeated application of tacrolimus ointment in adult patients with moderate to severe atopic dermatitis.
The study was conducted on an out-patient basis, with patients self-administering the
ointment twice daily at home. However, on Days 1 and 14 there was only a single application
of ointment and this was applied by the Investigator or his/her designee in the clinic. An
area of the affected skin was selected for skin biopsy of sufficient size for 5 biopsy
samples. The biopsy samples were taken from the same lesion(s) if possible or from an
adjacent lesion in the same anatomical area at all times. All areas selected for treatment
were treated with tacrolimus ointment 0. 1% for a period of two weeks with a follow up period
of one week. Two pharmacokinetic profiles (Days 1 and 14) and five skin biopsy samples (Days
1, 2, 15, 18 and 21) were taken.
Minimum age: 18 Years.
Maximum age: N/A.
