DDW: Budesonide improves dysphagia, histology, and endoscopic findings in EoE

After treatment, proximal, distal, and total EREFS scores correlated with peak eosinophil counts, a highly statistically significant finding.

Dr. Hirano said that the primary endpoints used in most EoE clinical trials to date have focused mostly on assessments of symptoms and histopathology, which have limitations. “Symptoms are difficult to quantify and often intermittent [and] they may improve as a result of changes in eating behavior and food avoidance,” he said. Patient-reported outcome instruments have been recently validated, “but have questionable utility in clinical practice” and histology “has shown limited correlation between degree of esophageal eosinophilia and symptom severity [and does not] assess for modeling, an important determinant of overall disease complications,” he added.

The utility of endoscopy in EoE includes the features that are present in vast majority of patients with EoE, and provides a gross assessment of overall disease activity, “both in terms of inflammatory and fibrostenotic features,” he said.

“Endoscopic outcomes are now emerging as clinically relevant endpoints of therapy of trials of eosinophilic esophagitis that supports and complements” symptom and histologic assessments, Dr. Hirano commented, adding that more studies are need to determine the “relative importance of these individual endoscopic features as well as the appropriate utilization of endoscopic parameters in disease management.”

The study was funded by Meritage Pharma, recently acquired by the Shire group of companies. All authors received research funds to conduct the study, and Dr. Hirano disclosed having worked as a consultant for Meritage. Dr. Dellon’s disclosures included receiving grant and research support from Meritage. Shire is developing the oral budesonide suspension formulation as a treatment for adolescents and adults with EoE.
