The subject cannot avoid systemic treatments (including systemic corticosteroids, immunotherapy, biologics or phototherapy) for AD during the study per the Investigator
The subject has previously received any systemic treatments, immunotherapy, biologics or phototherapy for AD within 12 months prior to study enrollment
Current or expected use of prohibited medications as described in Section 7, unless approved by the study Medical Monitor
The subject has concurrent contact dermatitis or history of anaphylactic reaction
