Dupixent® (dupilumab) Demonstrates Improved Esophageal Function in Eosinophilic Esophagitis (EoE) Phase 4 Trial

May 5, 2026 7:00 AM EDT

Dupixent showed significant and clinically meaningful improvements in both esophageal distensibility as well as disease-related structural changes and inflammation in the esophagus in adult patients with EoE at week 24 compared to placebo, in results presented at DDW

These results reinforce the roles of IL-4 and IL-13, two of the key and central drivers of type 2 inflammation, in EoE

EoE is a chronic, progressive disease that causes scarring and narrowing of the esophagus, making it difficult to swallow food, with more pronounced damage increasing the risk for severe symptoms
