Study to Evaluate the Response to Treatment and Safety of 0.03% Tacrolimus (FK506) Ointment Administered in Pediatric Patients With Moderate to Severe Atopic Dermatitis

A Long Term, Non-comparative, Multi-centre Study to Further Evaluate the Response to Treatment and Safety of 0.03% Tacrolimus Ointment Administered in Pediatric Patients With Moderate to Severe Atopic Dermatitis.

Objective of this study is to further assess the response to treatment and safety of 0.03% tacrolimus (FK506) ointment when used for 6 months in pediatric patients with moderate to severe atopic dermatitis, known to be responsive to topical steroids.

The main phase is 6 month duration, but the follow-up phase up to 12 months will allow the collection of RTT and safety data in a period which will include all seasons in each patient, to account for seasonal variability which strongly affect AD course.

Inclusion Criteria:

• Patient may be male or female of any ethnic group

• Patient known to be responsive to topical steroids

• Patient's legal representative has given written informed consent. If the patient is capable of understanding the purposes and risks of the trial written informed consent has been obtained from the patient as well. Female patients of childbearing potential must agree to maintain adequate birth control practice during the trial period and during the first four weeks after the end of the study
