Evaluation of the Efficacy of a Cosmetic Care in Subjects With Moderate to Severe Atopic Dermatitis, Treated by Systemic Treatments

An Exploratory and Proof of Concept Study to Evaluate the Efficacy of the Cosmetic Care Product RV4427C WM0071 in Subjects Suffering From Moderate to Severe Atopic Dermatitis, Treated and Controlled by Systemic Treatments and Their Needs and Expectations Regarding the Use of Emollient

Atopic dermatitis (AD) is a common chronic inflammatory skin disease, affecting both children (15- 20%) and adults (2-5%). The pathogenesis of AD is complex and multifactorial, including skin barrier dysfunction and immune dysregulation.

AD often requires a long management and has a major impact on quality of life. For mild to moderate disease, first-line treatment involves topical therapies including corticosteroids and calcineurin inhibitors. Patients with more severe and refractory symptoms require systemic treatments as phototherapy, conventional systemic treatments (cyclosporine, methotrexate…), biologics and JAK-inhibitors.

Regardless of the severity of the disease, additional basic topical treatment with emollient is the mainstay of the management. Emollients, commonly referred to as moisturizing creams are well known for their role in moisture retention, barrier repair and symptom control in AD.

Publications on emollient in atopic dermatitis are numerous but there are limited data on how patients with AD treated by systemic treatment use and evaluate emollients.

The aims of this study are to evaluate the efficacy of the cosmetic care product RV4427C WM0071 in subjects suffering from moderate to severe AD, treated and controlled by systemic treatments by assessing the cosmetic satisfaction, perceived effects and habits of use as regards to the use of the cosmetic care product RV4427C WM0071, and to qualify this population of subjects in terms of pathology, the state of their skin at this stage of their systemic treatment (controlled period), their habits, needs and expectations regarding the use of emollient.

This study will be conducted as an exploratory, proof of concept study in adult subjects suffering from moderate to severe AD, treated and controlled by systemic treatments.

3 visits are planned:

• Visit 1 (Day 1): Inclusion
• Visit 2 (from Day 2 to Day 8): Intermediate visit - remote visit for subject's questionnaire filling
• Visit 3 (Visit 2 + 28 days +/- 2 days): End-of-study visit - remote visit for subject's questionnaire filling
