Comparison of LimpiAD Cream 2.5% Plus Versus Its Vehicle and and a Basic Emollient in Patients With Atopic Dermatitis

The purpose of this clinical trial is to assess the efficacy and tolerability of LimpiAD, a medical device in the formulation of a 2.5% Plus cream, versus the Vehicle of LimpiAD 2,5% Plus cream, and versus a basic emollient in subjects with mild to moderate Atopic Dermatitis.

The objective of this clinical trial is to assess the efficacy and tolerability of LimpiAD, a medical device in the formulation of 2.5% Plus cream, versus the Vehicle of LimpiAD 2,5% Plus cream , and versus a basic emollient in subjects with mild to moderate Atopic Dermatitis.

STUDY DESIGN A controlled, 3-arms randomized, double-blind, multicentre clinical trial within subjects, stratified and balanced based on severity of the Atopic Dermatitis (AD) between LimpiAD 2.5% Plus cream, the Vehicle of LimpiAD 2.5% Plus cream and a basic standard treatment (basic therapy) of AD according to European Guidelines in pediatric subjects with mild to moderate AD.

SAMPLE SIZE Two hundred (200) subjects with Atopic Dermatitis, of whom at least 50 cases with mild severity Atopic Dermatitis (defined by EASI = Eczema Area and Severity Index = 1.0-7.0 and IGA= Investigator's Global Assessment =2) and 50 cases with moderate severity Atopic Dermatitis (defined by EASI 7.1-21.0 and IGA=3).

TREATMENT SCHEDULE AND METHODS Treatment with the investigational product or the control products will occur twice daily (morning and evening) for 8 weeks after cleansing of the treatment area. After the 8 weeks treatment period, the study subjects will undergo a follow-up visit after 12 weeks following the baseline visit (4 weeks after treatment completion).

Clinical assessments will be performed at baseline (T0), and after 2, 4, 8 and 12 weeks (T2, T4, T8 and T12) by means of a daily diary as a reminder.

Primary endpoint: statistically significant improvement of the EASI between T0 and T8 (p\<0.05) in the treatment arm (LimpiAD 2.5% Plus cream ) as compared to the Vehicle of LimpiAD 2.5% Plus cream.
