Official title

Open Label Exploratory Study to Evaluate the Effect of Dupilumab on Skin Barrier Function in Patients With Moderate to Severe Atopic Dermatitis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Primary Objective: \- Evaluate changes in skin barrier function with transepidermal water loss (TEWL) assessed after skin tape stripping (STS) in pre-defined lesional skin in participants with moderate to severe atopic dermatitis (AD) treated with dupilumab. Secondary Objectives: * Evaluate changes in skin barrier function with TEWL assessed after STS in pre-defined lesional and non-lesional skin in participants with moderate to severe AD treated with dupilumab in reference to normal skin of healthy volunteers. * Evaluate time course of skin barrier function with TEWL assessed before and after STS in pre-defined lesional and non-lesional skin in participants with moderate to severe AD treated with dupilumab in reference to normal skin of healthy volunteers.
