Evaluation of the Efficacy of Topialyse Baume barrière on Atopic Dermatis

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy and tolerability of a new SVR care product and to evaluate the reduction of the topical corticosteroids' consumption with this emollient care. Atopic dermatitis is a vicious circle that must be broken, but certain aggravating factors are added to this circle. There is a lot of talk about pollution but, more recently, studies have been carried out on the worsening role of dust mites on atopic skin. The SVR product is therefore based on it: TOPIALYSE Baume Barrière is a care product that is lipid-replenishing, repairing and protective: a triple reinforced action for 48 hours: anti-scratching, anti-irritation, and anti-external aggression.

Detailed Description
-----------------
1. RATIONALE The mainstay of treatment for Atopic dermatitis (AD) is use of emollient and topical medications. Topical corticosteroids are the gold standard of anti-inflammatory therapy in AD especially AD flare-ups, in order to reduce inflammation and pruritus. Their long-term use is associated with the risk of local and systemic adverse effects. The purpose of this study is to evaluate the efficacy and tolerability of TOPIALYSE Baume Barrière and to evaluate the reduction of the topical corticosteroids' consumption with this emollient care. 2 STUDY OBJECTIVES 2.1 PRIMARY OBJECTIVE: The main objective of this study is to evaluate the efficacy of the cosmetic product SVR TOPIALYSE Baume Barrière on the reduction of topical corticosteroid consumption in children from 3 months to 17 years old presenting mild to moderate atopic dermatitis (5 < SCORAD < 40), after 28 days of use. 2.2 SECONDARY OBJECTIVE: 2.2.1. To evaluate the efficacy of the study product after 28 and 56 days of use on children of 3 months to 17 years with mild to moderate atopic dermatitis by the following criteria: Number of flare-up SCORAD Amount of topical corticosteroid consumption Mean PO-SCORAD Quality of life Skin condition and functional skin signs 2.2.2 Evaluate the tolerance of the study product after 28 and 56 days of use on children 3 months to 17 years old with mild to moderate atopic dermatitis 2.2.3. To evaluate the persistent effect of the cosmetic product SVR TOPIALYSE Barrier Balm after 24 and 48 hours of stopping use on children from 3 months to 17 years old with mild to moderate atopic dermatitis 3 STUDY METHODOLOGY This is a multicentric, randomized and open-label study. It is an interventional study with minimal risks (Category 2). 3.1 EVALUATION CRITERIA (see outcomes part) 3.2 EVALUATION METHODS 3.2.1 Topical corticosteroid consumption Consumption of class 2 or 3 topical corticosteroids will be assessed throughout the study by the number of days of use and the weight of the topical corticosteroid tube per month. 3.2.2 SCORAD At D -37, D -7, D0, D28 and D56, the dermatologist calculates the objective SCORAD over the entire body. A. First, the investigator assesses the distribution of atopic dermatitis by calculating the extent. For each zone, the investigator evaluates the proportion of the zone considered affected by atopic dermatitis compared to the suggested maximum score. B. Second, the investigator scores the intensity of the following parameters: erythema, oedema/papules, oozing/crust, excoriation, lichenification and xerosis C. Finally, the investigator questions the subjects about their subjective symptoms: pruritus abd insomnia The total score of the objective SCORAD is obtained according to the following formula: SCORAD = A/5 + 7 B/2 + C 3.2.3 Skin condition assessment 3.2.4 IDQOL questionnaire 3.2.5 Local tolerance assessment 3.2.6 Cutaneous functional signs assessment 3.2.7 Study product questionnaire 3.2.8 Standardized photographs 4 SELECTION OF STUDY POPULATION Sixty-two children (62) will be enrolled in the study.

This part will only be done by the subject' parent and send to the study center. 7 STATISTICAL METHODS 7.1 BASELINE CHARACTERISTICS Continuous demographic variables (e.g. age, weight, and height) will be summarized, using mean, standard deviation, minimum, maximum and number of available observations. Qualitative demographic characteristics will be summarized by counts and percent. Other subject characteristics (anomalies in physical examination, prior medication, inclusion / exclusion checklist) will be listed only. 7.2 STATISTICAL ANALYSES Descriptive statistics (N, mean, standard error, min, max,) will be calculated by test product for each parameter. Prior to any statistical analysis, the normality of each variable will be tested using the Shapiro Wilks test of normality. Statistical Tests: For each normal variable, comparisons will be performed using a t-test for paired data. For each non normal variable, comparison will be performed using a Wilcoxon rank sum test. 7.3 NUMBER OF SUBJECTS CALCULATION In the treatment of atopic dermatitis, the use of a simple emollient makes it possible to reduce by about 10% the amount of topical corticosteroid used [33]. In the present study, it is expected that TOPIALYSE Baume Barrière applied 1 application/day will reduce the consumption of topical corticosteroid by at least 35% after 28 days of application based on the results of the study of GIORDANO-LABADIE et al, 2006. Calculation of the number of patients by the Arcsinus method shows that 31 patients would allow to detect a significant difference between TOPIALYSE Baume Barrière applied 1 application/day and the reference value 10% with a power of 95% at risk α =0.05 (bilateral test). It is also expected that TOPIALYSE Baume Barrière applied 1 application/2 days will lead to a comparable decrease, therefore 31 patients will also be included in this group.
