Efficacy and Safety of Dupilumab Treatment with Concomitant Topical Corticosteroids in Children Aged 6 Months to 5 Years with Severe Atopic Dermatitis

Atopic dermatitis (AD) is a chronic skin disease that is relatively common in infants and young children worldwide. Severe AD causes skin rashes and intense itch that strongly interfere with sleep quality and normal daily activities, thereby affecting the quality of life of patients and their families. When therapies for AD that are applied to the skin do not work, limited options are available to treat severe AD in children younger than 6 years. In this study, we evaluated the efficacy and safety of dupilumab in children aged 6 months to 5 years with severe AD, recruited from various sites in Europe and North America. Patients received 200 or 300 mg of dupilumab (based on the child’s weight) or placebo, together with mild steroids applied to the skin, every 4 weeks for 16 weeks. At the end of treatment, AD severity was greatly improved in patients receiving dupilumab, with 14% of patients achieving almost clear skin. Patients receiving dupilumab also experienced significant improvements in itch intensity, sleep quality, skin pain, and quality of life. Furthermore, dupilumab did not increase the risk of infections. This study demonstrates that dupilumab can be effective at treating severe AD in infants and young children, with important benefits for the quality of life of patients and their families.
