Study to Determine the Effect of an Anti-IgE Agent on Inflammatory Cells in the Skin of Atopic Dermatitis Patients
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Elevated levels of immunoglobuline E in blood are said to promote the occurence of atopic dermatitis; in fact, many patients with atopic dermatitis have high IgE levels. This study tried to explore whether the depletion of IgE from blood and skin might result in a change of immunological parameters and might alter the clinical course of the disease.

clinically significant laboratory abnormalities
a history of noncompliance to medical regimens and patients who were considered potentially unreliable
evidence of drug or alcohol abuse or other factors limiting ability to fully cooperate
any condition or prior/continuing treatment which, in the opinion of the investigator, should have rendered the patient ineligible for the study.
