Study Design and Study Participants
This was a double-blind, randomized, placebo-controlled trial of fluticasone in a 1:1 allocation ratio in the treatment of EoE. The study was approved by the Mayo Foundation Institutional Review Board. The trial is registered with http://ClinicalTrials.gov, NCT00275561. All subjects provided written informed consent.
Subjects were recruited from the Esophageal Clinic at Mayo Clinic Rochester where they were being seen for a new diagnosis of EoE. They were recruited by the research assistant
Participants
Patient flow is displayed in Figure 1. The patient drop-out rate of 28.6% (6 of 21) in the placebo group was not significantly different from 9.5% (2 of 21) in the treatment group (P = .24). The causes of drop-out were travel in 2 patients, scheduling in 3 patients, family issues in 2 patients, and change of mind on study involvement 1 week after initiation in 1 patient. No patients dropped out for side effects or failure of response to treatment. No patients were excluded from analysis as a
Discussion
This was a double-blind, randomized, placebo-controlled trial of topical aerosolized fluticasone in the treatment of adults with EoE and symptomatic dysphagia. This was a negative study for the primary end point of dysphagia relief despite a strongly positive result for the secondary end point of decreased esophageal eosinophilia.
The complete dysphagia response with fluticasone by ITT (42.9%) or per protocol (PP) (47.4%) was no better than placebo (28.6% and 40.0%, respectively). The PP

2022, Digestive and Liver DiseaseCitation Excerpt :The disease predominantly presents in young males with a peak incidence between 20 and 40 years of age but can also occur in females and at any age. Adolescences and adults typically experience intermittent dysphagia and food impactions, which can be related to luminal abnormalities [1]; however, symptoms occur even when the esophagus appears endoscopically normal and a documented histological remission may not lead to the resolution of symptoms [38,56]. From a clinical point of view, a possible explanation for this phenomenon may be the presence of an underlying motor disorder of the esophagus.
