Description

Summary

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).

Official Title

A Phase 4, Randomized, Multicenter, Double-blind, Parallel-group, 24 Weeks, Placebo-controlled Study Followed by 104 Weeks Open-label to Assess Dupilumab Efficacy on Esophageal Function and Remodeling in Adult Participants With Eosinophilic Esophagitis (EoE)

Details

The duration per participant will be up to 152 weeks.
