A long-term observational registry in patients with atopic dermatitis (AD) initiating treatment with DUPIXENT® (dupilumab)

This is a prospective observational study conducted to (1) characterize the patients who receive DUPIXENT® for AD in a real world setting with respect to their medical history, socio-demographic and disease characteristics, and prior and concomitant treatments of AD; (2) characterize real world use patterns of DUPIXENT® for AD (eg, most commonly used regimens by line of therapy, reason for initiation of new treatments, concomitant therapies, treatment durations and reasons for discontinuation and/or switching); (3) assess the long-term effectiveness of DUPIXENT® in AD patients in a real world setting; (4) assess comorbid atopic conditions, patterns of use and effects of treatment in comorbid atopic conditions in patients who receive DUPIXENT® for AD; and (5) collect safety data on study participants

Key Inclusion Criteria:

• Male or female, 12 years of age or older at the baseline visit. NOTE: Adolescent patients (at least 12 years old, but less than 18 years) are eligible in the US or Canada only after DUPIXENT receives the respective country's regulatory approval for use in this age group.
• Initiating treatment with DUPIXENT® as standard-of-care for AD according to the country-specific prescribing information (Note: Participants will be screened when they received their initial prescription for DUPIXENT®).
• Willing and able to comply with study-related activities.
• Able to understand and complete study-related questionnaires.
• Provide signed informed consent or parental/legal guardian consent plus patient assent, where applicable.

Key Exclusion Criteria:

• Patients who have a contraindication to the drug according to the country-specific prescribing information label.
• Any condition that, in the opinion of the investigator, may interfere with patient's ability to participate in the study, such as short life expectancy, substance abuse, severe cognitive impairment, or other co-morbidities that can predictably prevent the patient from adequately completing the schedule of visits and assessments.
• Prior use of dupilumab within 6 months of the screening visit, or within 6 months of the baseline visit if screening and baseline occur on the same day.

NOTE: Other protocol defined Inclusion/Exclusion criteria apply.

The target population comprises adult and adolescent patients (male or female, ≥12 years old), who are initiating treatment with DUPIXENT® for AD according to the country-specific prescribing information.
