Dermatitis, Atopic
Conditions
Brief summary
The purpose of this study is to estimate the systemic exposure to tacrolimus in infants with atopic dermatitis after repeated application of tacrolimus ointment. Efficacy of tacrolimus ointment, evaluated by examination of treated areas, will also be measured.
Detailed description
This is a multi-centre, double-blind, randomised phase II pharmacokinetic study in infants (3 - 24 months old) suffering from atopic dermatitis and requiring treatment with mid potency topical steroids. Patients will primarily be stratified into three groups according to percentage body surface area to be treated and subsequently randomised into treatment groups of once a day (UID) or twice a day (BID) tacrolimus ointment (0.03%) regimens. There will ultimately be a total of six groups. The study will be conducted on an out-patient basis, with each patient's parent/legal representative administering the ointment at home. However all medications on days 1 and 14 will be applied in the clinic by the Investigator or his/her designee, as will the morning application on day 4. The ointment application period will be two weeks with a follow-up period of four days. All patients enrolled into the study, who applied at least one dose of study medication and who benefited from treatment will be given the opportunity to enter a long-term study to follow (FG-506-06-33). The patient will be entered into one of the following three groups: Stratification Group I Application area of 5 - 20% Stratification Group II Application area of \> 20 - 40% Stratification Group III Application area of \> 40% Within these groups the patients will be randomised to either UID or BID.
