Drug Survival of Target Therapies in Atopic Dermatitis

Overview

This is an observational study with drug to evaluate the drug survival of approved target therapies in atopic dermatitis. Patients affected by moderate-severe atopic dermatitis who will start therapy with approved target drugs (dupilumab, tralokinumab, upadacitinib, abrocitinib, baricitinib) for AD will be enrolled. Patients already on therapy with these drugs will also be included. During the baseline and follow up visits, clinical and demographic data will be collected, according to ordinary clinical practice. Current or retrospective disease severity scores will also be collected. Among the main: Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Dermatology Life Quality Index (DLQI), Pruritus Numerical Rating Scale (NRS pruritus), Sleep Numerical Rating Scale (NRS sleep), Patient Oriented Eczema Measure (POEM).

Atopic dermatitis (AD) is a chronic, inflammatory skin disease with a prevalence of 10% in adults and 20% in children. It is of primary importance to select the best treatment option as as relapses occur quickly after discontinuation. Drug survival rate reflects efficacy, tolerability, and safety of a drug, influencing disease management and healthcare costs. AD treatment has been revolutionized by new treatments that include monoclonal antibodies (dupilumab, tralokinumab) and JAK inhibitors (abrocitinib, baricitinib, upadacitinib). This observational study evaluates the 12-month drug survival of these approved treatments in moderate-to-severe atopic dermatitis, assessing their safety. The study also aims to evaluate the relationship between drug survival and clinical, laboratory, and pharmacological factors. Patients affected by moderate-severe atopic dermatitis who will start therapy with approved target drugs (dupilumab, tralokinumab, upadacitinib, abrocitinib, baricitinib) for AD will be enrolled. Patients already on therapy with these drugs will also be included. During the baseline and follow up visits, clinical and demographic data will be collected, according to ordinary clinical practice. Current or retrospective disease severity scores will also be collected. Among the main: Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Dermatology Life Quality Index (DLQI), Pruritus Numerical Rating Scale (NRS pruritus), Sleep Numerical Rating Scale (NRS sleep), Patient Oriented Eczema Measure (POEM).
