A Study Assessing Esophageal Function and Remodeling With Dupilumab Compared With Placebo for 24 Weeks Followed by 104 Weeks Open Label in Adult Participants With EoE (REMOdeling With Dupilumab in Eosinophilic Esophagitis Long-term Trial)

Study Purpose

This is parallel, Phase 4 study which consists of a 24 week (0.5 years) randomized, double blind, placebo controlled, 2-arm treatment period followed by an open label segment of 104 weeks (2 years) for a total of 128 weeks (2.5 years) to evaluate the effect of dupilumab treatment on esophageal function, and remodeling in adults with eosinophilic esophagitis. Duration of study period (per participant)

  • - Screening period: Up to 12 weeks before Week 0.
  • - Randomized double-blind period: 24 weeks.
  • - Open label period: 104 weeks.
  • - Post Investigational Medicinal Product (IMP) intervention follow-up period: up to 12 weeks or until the participants switch to commercialized dupilumab, whatever comes first.
There will be ten (10) site visits, and five
  • (5) direct-to-participant IMP delivery visits (except if prohibited by local regulatory authorities or if participant is not willing.
In this case, IMP will be dispensed at the study site).

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
