Plain English Summary
Background and study aims
Seborrheic dermatitis (SD) is a common condition that causes redness of the skin, flaking/scaling and dandruff. It is thought that excess oil production in the skin and overgrowth of Malassezia furfur (a type of yeast fungus that is normally found on the skin) can contribute to SD. Nutradeica is a cream that contains agents that reduce fungal growth, oil production and inflammation. This study aims to investigate whether Nutradeica can treat SD.
Who can participate?
Men aged 21-65 years who have SD on their face and chest, but otherwise are in good health.
What does the study involve?
All participants will apply the cream to their face and chest twice daily for 14 days. Before the start of treatment, at 7 days after the start of treatment and at 14 days after the start of treatment, they will have skin scrapings and small skin samples taken, fill in some forms to assess their SD symptoms and be assessed by the researchers.
What are the possible benefits and risks of participating?
The possible benefit to participants is that the cream may improve their SD symptoms and their microbial skin flora may be re-balanced. The possible risks related to the skin sample procedure are represented, in the worst cases, by a spot about 2 mm of slightly different complexion (lighter or darker) than the surrounding skin or a small scar of 2 mm, similar to a chicken pox scar
Where is the study run from?
Dermatology Unit of University of Naples Federico II (Italy)
When is the study starting and how long is it expected to run for?
May 2017 to April 2019
Who is funding the study?
ISDIN, the company that makes Nutradeica

Experimental, prospective, open, monocenter, clinical trial for the evaluation of a novel cream used to improve the condition of seborrheic dermatitis topically applied on face and chest in patients with seborrheic dermatitis
The pathogenesis of seborrheic dermatitis (SD) is multifactorial and traditional treatments may not target all aspects of them.The aim of this study was to evaluate short term anti-fungal, anti-microbial, anti-inflammatory and anti-pruritus properties of a novel non-steroidal cream (NSC) containing piroctone olamine, zinc PCA, hydroxyphenyl propamidobenzoic acid, biosaccharide gum-2 and stearyl glycyrrhetinate in patients with face and chest SD.

Patients were instructed to apply Nutradeica cream twice daily on the face and on the chest for 14 days. The investigator evaluated their skin condition at first visit and after 7 and 14 days of product use. A physican will perform skin scale scraping from the face (wings of the nose) and the chest through the study. In addition, the physician will perfom a biopsy (2 mm diameter) in the same area on the chest at first visit and after 7 days product use.
Nutradeica (containing active agents piroctone olamine , zinc PCA, hydroxyphenyl propamidobenzoic acid, biosaccharide gum-2 and stearyl glycyrrhetinate)
Primary outcome measure
1. Severity of seborrheic dermatitis assessed using a scoring index (SI) evaluating erythema, desquamation, itching and irritation at baseline and after 7 and 14 days of treatment
2. Seborrheic dermatitis severity assessed using the Investigator's Global Assessment Score (IGA) at baseline and after 7 and 14 days of treatment
Secondary outcome measures
1. Patient evaluation of erythema assessed using a visual analog scale at baseline and after 7 and 14 days of treatment
2. Patient evaluation of scaling assessed using a visual analog scale at baseline and after 7 and 14 days of treatment
3. Patient evaluation of itching assessed using a visual analog scale at baseline and after 7 and 14 days of treatment
4. Patient evaluation of sensation of heat assessed using a visual analog scale at baseline and after 7 and 14 days of treatment
5. Patient evaluation of pain assessed using a visual analog scale at at baseline and after 7 and 14 days of treatment
6. Patient evaluation of irritation assessed using a visual analog scale at baseline and after 7 and 14 days of treatment
7. Patient evaluation of seborrheic dermatitis severity change assessed using the Patient Global Assessment (PGA) after 7 and 14 days of treatment
8. Antifungal effect assessed by quantifying Malassezia furfur colony-forming units from skin scrapings at baseline and after 7 and 14 days of treatment
9. Antimicrobial effect assessed by quantifying Staphylococcus epidermidis colony-forming units from skin scrapings and gene expression of antimicrobial peptides (HBD2 and HBD3) at baseline and after 7 and 14 days of treatment
10. Anti-inflammatory effect assessed by quantifying gene expression of IL-1α, IL-1β, IL-6, IL-8 and TNF-α in skin biopsies at baseline and after 7 and 14 days of treatment
11. Anti-pruritic effect assessed by quantifying gene expression of cathepsin S (CTS) and L-histidine decarboxylase (HDC) in skin biopsies at baseline and after 7 and 14 days of treatment
12. Tolerability assessed by quantifying adverse events recorded by the investigator or reported by patients during the study
