Difference in number of days/week corticosteroid use between verum and placebo group over 12 weeks [ Time Frame: baseline, 12 weeks ]
Same as current
No Changes Posted
  • Difference in mean grams/week topical corticosteroid use between verum and placebo group [ Time Frame: baseline, 12 and 20 weeks ]
  • Proportion of patients with AD who indicate to have used less corticosteroids at week 2 and 12, as compared to baseline and at week 20 as compared to the 12 week treatment period [ Time Frame: baseline, 2, 12 and 20 weeks ]
  • Change in Eczema Area and Severity Index (EASI) from baseline to week 2, 6, 12 and 20 [ Time Frame: baseline, 2, 6, 12 and 20 weeks ]
  • Change in Patient Orientated Eczema Measurement (POEM) from baseline to week 2, 6, 12 and 20 [ Time Frame: baseline, 2, 6, 12 and 20 weeks ]
  • Change in Investigator Global Assessment (IGA) scale from baseline to week 2, 6 and 12 and week 20 [ Time Frame: baseline, 2, 6, 12 and 20 weeks ]
  • Change in Pruritis Numerical Rating Scale (Pruritis NRS) from baseline to week 2, 6, 12 and week 20 [ Time Frame: baseline, 2, 6, 12 and 20 weeks ]
  • Mean time to flare from baseline through week 12 and from week 12 through week 20. Flare is defined is an exacerbation that requires the need of any stronger topical therapy, an increase in dosage of the topical therapy or the need of a systemic therapy. [ Time Frame: baseline, 12 and 20 weeks ]
  • Number of flares through week 12 [ Time Frame: baseline, 12 weeks ]
  • Change in Skindex-29 score from baseline to week 12 and week 20 [ Time Frame: baseline, 12 and 20 weeks ]
  • Proportion of patients with a reduction of S. aureus from baseline to measurement 1 (0,5 hour after baseline) as determined by semi quantitative culture [ Time Frame: baseline, 1 day ]
  • Proportion of patient with a > 1 log reduction of S. aureus from the lowest measurement (visit 1 or visit 2a) to week 2 and week 12 as determined by quantitative polymerase chain reaction (qPCR) [ Time Frame: baseline (visit 1 or 2a), 2 and 12 weeks ]
  • Change in relative abundance of bacteria: determined by 16 Svedberg units ribosomal ribonucleic acid (16s rRNA) sequencing [ Time Frame: baseline, 2, 12 and 20 weeks ]
  • Incidence of (serious) adverse device events from baseline through the end of the study, evaluated by medical check-ups, including vital signs [ Time Frame: baseline, 20 weeks ]

The Effect of Gladskin on Disease Severity and the Skin Microbiome, Including Staphylococcus Aureus, in Patients With Atopic Dermatitis
The Effect of Gladskin on Disease Severity and the Skin Microbiome, Including Staphylococcus Aureus, in Patients With Atopic Dermatitis
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.
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.
