E.5 End points |
E.5.1 | Primary end point(s) |
Pharmacodynamic endpoints • Microbiome (for skin: microbiota and mycobiota, for gut: microbiota) • Mycology (mycobiome and culture) • Sebum measurement (Sebumeter) • Skin barrier function by Trans Epidermal Water Loss (TEWL) • Skin morphology by Optical coherence tomography (OCT) • Changes in stratum corneum lipid composition by liquid chromatography-mass spectrometry (LC-MS) Efficacy endpoints • Seborrheic dermatitis area severity index (SDASI) • Investigator Global Assessment (IGA) • Area of involvement (% body surface area affected by facial SD) • Patient reported outcomes (5D- itch scale, daily NRS itch, DLQI) • Standardized facial photography by VISIA-CR Tolerability / safety endpoints Adverse events (AE) will be collected throughout the study, at every study visit.
