Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Colonization with Staphylococcus aureus is related to inflammation in atopic dermatitis. Gladskin is a product for topical use containing the proprietary enzyme Staphefekt SA.100, which has the ability to specifically lyse the cell wall of S. aureus. The investigators hypothesize that Staphefekt decreases S. aureus colonization of the skin and consequently decreases symptoms of atopic dermatitis.The goal of this study is to determine the effect of Staphefekt on the use of topical corticosteroids in patients with atopic dermatitis. Secondary goals are to retrieve information about the effect on clinical symptoms, quality of life, growth characteristics of Staphylococcus aureus and the further microbiome.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multi center intervention study with a placebo controlled, double blind and randomized design. After standardization of corticosteroid treatment (triamcinolone acetonide 0.1% cream), patients will be randomized in a 1:1 fashion to either treatment with Staphefekt SA.100 for 12 weeks or treatment with a placebo for 12 weeks. Topical corticosteroid use will be evaluated 2, 6, 12 and 20 weeks after start of the intervention. Swabs of the skin, nose and throat will be collected at baseline, week 2, 12 and 20.
