Study of Patients Receiving DUPIXENT® for Atopic Dermatitis (AD) (PROSE)

December 22, 2025 updated by: Regeneron Pharmaceuticals

A Prospective Observational Study of Patients Receiving DUPIXENT® for Atopic Dermatitis

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

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.

Description

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.
