Prospective, Observational, Longitudinal Study in Pediatric Patients With Moderate to Severe Atopic Dermatitis Whose Disease is Not Adequately Controlled With Topical Prescription Therapies or When Those Therapies Are Not Medically Advisable

Primary Objectives: * To describe the characteristics of pediatric patients with moderate to severe atopic dermatitis (AD) whose disease is not adequately controlled with topical therapies or when those therapies are not medically advisable. * To evaluate the time-course of AD and selected atopic comorbidities. Secondary Objectives: * To characterize disease burden and unmet need. * To describe real-world treatment patterns (eg, dosing regimens, treatment duration, and reasons for discontinuation and/or switching). * To document the real-world effectiveness and safety of treatments.
