Inclusion Criteria

• Participants who stopped dupilumab treatment due to intolerance or adverse events (AEs) to the drug may enter the study with no required prior length of dupilumab treatment.
• Participants who stopped dupilumab treatment due to cost or loss of access to dupilumab (for example, insurance coverage) may enter the study with no required prior length of dupilumab treatment.
• Participants who have chronic AD that has been present for ≥1 year before screening.
• Have EASI ≥16 at baseline
• Have IGA score ≥3 (Scale of 0 to 4) at baseline
• Have ≥10% body surface area (BSA) of AD involvement at baseline
• Have a history of inadequate response to treatment with topical medications; or determination that topical treatments are otherwise medically inadvisable.
• Adolescents body weight must be ≥40 kg at baseline.

Exclusion Criteria
