Dupilumab versus swallowed fluticasone for narrowing (fibrostenotic) eosinophilic esophagitis

Comparative study of dupilumab and fluticasone in management of fibrostenotic Eosinophilic Esophagitis; a pilot and feasibility clinical trial.

NIH-funded research University of Colorado Denver · NIH-11333745

This trial compares dupilumab injections with swallowed fluticasone in people who have fibrostenotic eosinophilic esophagitis to try to improve esophageal narrowing and swallowing symptoms.

What this research studies

You would be randomly assigned to receive either dupilumab (a biologic injection) or swallowed topical fluticasone and then followed over time. Doctors will use endoscopy with EndoFLIP to measure esophageal distensibility (how well the esophagus stretches) and will collect patient-reported swallowing symptoms and quality-of-life measures. The study is a small pilot to test whether the trial procedures, measurements, and recruitment work before a larger trial. Researchers may also collect blood or tissue samples to learn about inflammation and scarring in the esophagus.

Who could benefit from this research

Good fit: People with fibrostenotic (narrowing or stiff) eosinophilic esophagitis who have ongoing swallowing problems and are candidates for biologic or topical steroid treatment would be the ideal participants.

Not a fit: People without fibrostenotic features, those whose swallowing problems are due to other conditions, or those unwilling to undergo injections or endoscopic testing may not receive benefit from this trial.

Why it matters

Potential benefit: If successful, this could identify which treatment better reduces esophageal narrowing and improves swallowing and quality of life for people with fibrostenotic EoE.

How similar studies have performed: Biologics such as dupilumab and swallowed topical steroids have both shown benefit in EoE, but direct head-to-head comparisons specifically in fibrostenotic EoE are novel.
