A Study to Determine the Safety and Tolerability of Dupilumab (REGN668/SAR231893) in Patients Aged ≥6 to <18 Years With Atopic Dermatitis (Eczema)

The primary objective of the study is to characterize the safety and pharmacokinetics (PK) of dupilumab in pediatric patients with moderate-to-severe atopic dermatitis (AD) (for adolescents ≥12 to \<18 years of age) or severe AD (for children ≥6 to \<12 years of age). The secondary objective of the study is to explore the immunogenicity and efficacy of dupilumab in pediatric patients with moderate-to-severe AD (for adolescents ≥12 to \<18 years of age) or severe AD (for children ≥6 to \<12 years of age).
