Infections in children and adolescents treated with dupilumab in pediatric clinical trials for atopic dermatitis—A pooled analysis of trial data.

Background/Objective: Patients with moderate‐to‐severe atopic dermatitis (AD) have increased risk of cutaneous and extracutaneous infections. Dupilumab has previously been associated with reduced risk of serious/severe infections and non‐herpetic skin infections in adults with moderate‐to‐severe AD. This analysis assessed infection rates with dupilumab versus placebo in pediatric patients with moderate‐to‐severe and severe AD participating in clinical trials. Methods: This is a pooled analysis from two 16‐week, randomized, placebo‐controlled, phase 3 clinical trials of dupilumab: monotherapy in adolescents aged 12–17 years with moderate‐to‐severe AD (LIBERTY AD ADOL, NCT03054428) and with concomitant topical corticosteroids in children aged 6–11 years with severe AD (LIBERTY AD PEDS, NCT03345914). Data were pooled according to treatment received: placebo/approved dupilumab doses/other studied dupilumab doses/all dupilumab doses. Exposure‐adjusted rates (patients with ≥1 event per 100 patient‐years [nP/100 PY]) were used to compare treatment groups. Results: Overall, 612 patients were included: 205 received placebo and 407 received dupilumab (261 received approved dupilumab doses and 146 received other studied dupilumab doses). Overall infection rates were numerically lower with dupilumab versus placebo (nP/100 PY: placebo, 227; approved dupilumab, 173; other dupilumab, 206; all dupilumab, 184). Total skin infections were numerically less frequent in all dupilumab‐treated groups versus placebo (nP/100 PY: placebo, 67; approved dupilumab, 30; other dupilumab, 46; all dupilumab, 36). Conclusions: These data suggest that dupilumab treatment in children and adolescents with AD does not increase infection risk overall and is associated with lower rates of skin infections compared with placebo.
