Clinical Trial Summary

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.

Description:

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.

• Baseline treatment with anti-inflammatory drugs, antihistamines, antitussives and/or inhaled steroids in the 2 previous weeks, retinoids and/or immunosupressants in the previous 6 months.

• Use of systemic steroids in the 4 weeks prior to the study.

• Intense and prolonged sun exposure in the 30 days preceding the screening.

• Severe AD (EASI > 21) or mild/moderate AD requiring any local and/or systemic treatment comprised in the prohibited treatments included in the exclusion criteria;

• Hypersensitivity to the study products.

• Acute or chronic skin diseases - except for atopic eczema - which may invalidate clinical assessments or overlap with AD skin picture;

• Systemic diseases which may affect the subject's safety or wellbeing or interfere with skin response.

Related Conditions & MeSH terms

• Eczema

Intervention

Device:
• LimpiAD 2,5% plus cream
A topical formulation that contains Hyaluronic Acid conjugated with a bacterial wall fragment of Cutibacterium species (HAc-40) and an emollient base. LimpiAD exerts its post-biotic action through the seizure/ trapping and inactivation of catabolites and / or toxins produced by S. aureus as well as protecting the hydrolipidic film, especially in case of dryness, itching, and, in conditions of altered microbiome

Other:
• Vehicle
Vehicle of LimpiAD 2.5 % plus cream which has the qualities of an emollient technically enriched with active ingredients known for their use in AD ("plus" emollient) - having the same ingredients of LimpiAD 2.5% Plus but without the HAc-40 component.
• Emollient
Standard emollient used as neutral control, having only a moisturizing and skin barrier action, which represents the basic standard treatment (basic therapy) of atopic dermatitis according to the European Guidelines.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Eczema Area and Severity Index (EASI)	The change shall be calculated by comparing the baseline value (T0) with the 2 weeks (T4), 4 weeks (T4) and 8 weeks (T8) values of LimpiAD 2.5% Plus cream versus the Vehicle of LimpiAD 2.5% Plus cream in terms of: - score reduction detected (total EASI score); INTERPRET EASI: Clear 0; Almost clear 0.1-1.0 ; Mild 1.1-7.0 ; Moderate 7.1-21.0 ; Severe 21.1-50.0; Very severe 50.1-72.0	Baseline (T0), 2 weeks (T2), 4 weeks (T4) and 8 weeks (T8)
Secondary	Change in Investigator Global Assessment (IGA) scale for Atopic Dermatitis	The change shall be calculated by comparing the baseline value (T0) of IGA with the 2 weeks (T2), the 4 weeks (T4) and 8 weeks (T8) values in the treatment arm with LimpiAD 2.5% Plus cream as compared to the other 2 arms.; INTERPRET IGA: 0 - Not affected; 1 - Little affected; 2 - Mild erythema; 3 - Moderate erythema; 4 - Severe Marked erythema	Baseline (T0), 2 weeks (T2), 4 weeks (T4) and 8 weeks (T8)
