A Study Evaluating the Safety and Efficacy of QGE031 in Atopic Dermatitis Patients

A Randomized, Double-blind, Placebo Controlled, Parallel Group, Proof of Concept Study Evaluating the Efficacy, Safety, Pharmacokinetics and Pharmacodynamics of QGE031 in the Treatment of Patients With Moderate to Severe Atopic Dermatitis

The study will assess the safety and efficacy of QGE031 in the treatment of moderate to severe atopic dermatitis patients. In addition, QGE031 levels in the blood will be measured and the effect of QGE031 on markers in the blood and skin will be evaluated. Comparisons of the effect of QGE31 will be made with placebo and also cyclosporine, a treatment already established as being effective in atopic dermatitis.
