Study Overview

This observational research study is to better understand patients with eosinophilic esophagitis (EoE) who have recently been prescribed DUPIXENT® (dupilumab).

The purpose of this research study is to look at how DUPIXENT is used in normal care of patients with EoE.

Possible benefits to others include a better understanding of EoE and helping to inform research and clinical trial design leading to treatment decisions in this patient population going forward.

Patient questionnaires will measure the following:

  • How EoE makes one feel
  • EoE signs and/or symptoms, eg, how difficult it is to swallow
  • How EoE affects quality-of-life
  • How EoE impacts aspects of daily life
  • How EoE symptoms have changed throughout the study

Eligibility Criteria

You may be eligible for this study if you meet the following criteria:

  • Conditions: Eosinophilic Esophagitis (EoE)
  • Age: 1 year or above
  • Gender: All

Key Inclusion Criteria:

  1. Initiating treatment with DUPIXENT® for EoE according to the USPI
  2. Participants aged ≥12 years and caregivers or legal guardians of participants aged <12 years must be able to understand and complete registry-related questionnaires

Key Exclusion Criteria:

  1. Patients who have a contraindication to DUPIXENT® according to the USPI
  2. Treatment with DUPIXENT® within the 6 months prior to the screening assessment
  3. Participation in an ongoing interventional study on or within 6 months of the baseline assessment. Once enrolled in registry, participation is allowed in other ongoing studies (at the discretion of the registry investigator)

NOTE: Other protocol defined inclusion/exclusion criteria apply

This study investigates eosinophilic esophagitis (EoE) in patients who have been prescribed an investigational medication as part of their standard care. The purpose is to understand the experiences of these patients and how the condition affects them.

The study focuses on observing how the investigational medication is used in routine care for EoE patients. It aims to gather information on the condition's impact on quality of life and daily activities without altering the treatment participants receive.

  • Who can participate: Participants must be 12 years or older, or have caregivers/legal guardians who can complete questionnaires for those under 12. They should be starting treatment with DUPIXENT® specifically for eosinophilic esophagitis. Exclusion criteria include prior treatment with DUPIXENT® and participation in other studies.
  • Study details: Participants will complete questionnaires about their feelings, symptoms, and how eosinophilic esophagitis affects their daily life and quality of life. This observational study does not involve changing any treatments. DUPIXENT® is part of the standard care in this study.
