Abstract:

INTRODUCTION: Dupilumab, the first US Food and Drug Administration-approved treatment for eosinophilic esophagitis (EoE), lacks real-world data on use and effectiveness. METHODS: We conducted a retrospective cohort study of 70 patients with EoE prescribed dupilumab, comparing prescriber type, indication, follow-up, and response. RESULTS: Indications varied with gastroenterologists commonly prescribing for treatment-refractory cases and allergists as first-line therapy. Endoscopic assessment was lacking in 25.9%, but those with follow-up showed high histologic remission (92.3% first-line and 85% previous treatment failure). DISCUSSION: Dupilumab demonstrates effectiveness across EoE severity, including milder disease without previous treatment failure. Improving follow-up and assessing cost-effectiveness will help clarify its role in the treatment algorithm.
