| Measure | Time frame |
|---|---|
| Pharmacodynamic endpoints Pharmacodynamic effects of Omiganan will be assessed at the time points indicated in the Visit and Assessment Schedule (Table 1) by: - Local (biopsy) biomarkers (IFN-alpha, IFN-gamma, IL 6, IL13, IL31, eotaxin3) - Microbiome of skin lesions (in comparison to non-lesional skin) - Bacterial colonization of skin lesions (S. aureus) - Transepidermal water loss of lesional and non-lesional skin - Transdermal analysis patch (TAP) biomarkers: IFN-gamma, IL-6, IL-10, IL-13, IL-31, eotaxin3. - Circulating cytokines (TARC, IFN-alpha, IFN-gamma, IL 6, IL13, IL31, eotaxin3) - Thermography Efficacy endpoints Efficacy will be assessed at the time points indicated in the Visit and Assessment Schedule (Table 1) by: - Clinical assessment using SCORAD; EASI and IGA - Patient-reported itch (daily NRS and weekly POEM) - General clinical assessment - Standardized total body clinical photography - Diary for drug compliance and use of escape medication - Partial / complete clearance of AD lesions | — |

| Tolerability / safety endpoints Adverse events (AE) will be collected throughout the study, at every study visit. Laboratory safety testing, 12-Lead ECGs and vital signs will be performed and measured multiple times during the course the study according to the Visit and Assessment Schedule. Pharmacokinetic endpoints Following PK samples will be analyzed: - Day 28; Pre-dose, 10, 20, 30, 60, 120 and 180 minutes | — |
