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:
