A Study to Observe How Pediatric Patients With Severe Atopic Dermatitis Despite Less Extensive Skin Lesions Respond to Dupilumab Treatment (AD-BEASCUITS)

A Prospective Observational Study of Pediatric Patients With Severe Atopic Dermatitis Despite Less Extensive Skin Lesions (Eczema Area and Severity Index Score < 16 for Adolescents and < 21 for Children) Receiving Dupilumab

In adolescents treated with dupilumab, clinical trials showed significant improvement of atopic dermatitis (AD) signs and symptoms, with a good safety profile. In these clinical trials, only patients with Eczema Area and Severity Index (EASI) score greater than or equal to (≥) 16 were enrolled, and effectiveness on sensitive/visible areas was not specifically evaluated. Further data about the effectiveness of dupilumab in adolescent and children participants with moderate to mild EASI score and severe itching and/or localized AD to better understand the potential clinical benefits of dupilumab in these populations.

The main objective of the study us to assess the real-word effectiveness and safety of dupilumab in pediatric patients (age 6 months-17 years) who suffer from severe AD with EASI score < 16 for adolescents (age 12-17 years) and < 21 for children (age 6 months-11 years), and who are eligible for systemic therapy according to Italian reimbursement criteria.
