Study of Dupilumab in Adult Participants With Active Eosinophilic Esophagitis (EoE)
A Randomized, Double-Blind, Parallel, Placebo-Controlled Study of the Efficacy, Safety and Tolerability of Dupilumab in Adult Patients With Active Eosinophilic Esophagitis
The primary objective of the study is to assess the clinical efficacy of repeat subcutaneous (SC) doses of dupilumab, compared with placebo, to relieve symptoms in adult participants with active, moderate to severe Eosinophilic Esophagitis (EoE).
The secondary objectives of the study are:
- To assess the safety, tolerability, and immunogenicity of SC doses of dupilumab in adult participants with active, moderate to severe EoE
- To assess the effect of dupilumab on esophageal eosinophilic infiltration
- To evaluate the pharmacokinetics (PK) of dupilumab in adult participants with EoE

The items are graded on a 5-point scale: 1 (Not at All), 2 (Slightly), 3 (Moderately), 4 (Quite a bit), and 5 (Extremely).
The EoE-QOL-A score is the average obtained by dividing the total score by the number of questions (for participants without disease, 120/30 = 4).

Treatment-emergent adverse events (TEAEs) were defined as adverse events (AEs) that developed or worsened or became serious during the on-treatment period (time from the first dose of study drug up to the end of study (Week 28).
A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-participant hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event.
Any TEAE included participants with both serious and non-serious AEs.
