The
and Sanofi.If approved, dupilumab would be the first biologic approved for children in this age group in the United States, according to the statement. The proposed indication is as add-on therapy for children with moderate to severe AD not adequately controlled with topical prescription therapies or for whom topical therapies are not advised.

Approximately 85%-95% of atopic dermatitis patients develop symptoms before 5 years of age, and these symptoms often continue into adulthood, with an increased risk of skin infections and a significant impact on quality of life, according to the statement.
The sBLA is based on data from a phase 3 pivotal study of 162 children aged 6 months to 5 years in which dupilumab was added to standard-of-care topical corticosteroids, presented in December 2021. In the study, dupilumab plus standard of care significantly improved skin clearance and reduced overall disease severity and itch at 16 weeks compared with standard of care alone. Overall, 28% of the children randomized to dupilumab achieved the primary endpoint of clear or almost-clear skin, compared with 4% with those on standard of care alone (P < .0001), according to the manufacturers. Patients in the dupilumab group received either 200 mg (for children weighing ≥ 5 to < 15 kg) or 300 mg (for children weighing ≥ 15 to < 30 kg) every 4 weeks. Safety results were similar to those seen with dupilumab for children aged 6 years and older.
Conjunctivitis and herpes infections were among the most common adverse events associated with dupilumab in the study, according to the statement.
The target action date for the FDA decision on this application is June 9, 2022.
