HOUSTON — Budesonide oral suspension was associated with improvements in dysphagia in patients with eosinophilic esophagitis, according to phase 3 study results presented at the 2019 Annual Scientific Meeting of the American College of Allergy, Asthma, & Immunology, held November 7 to 11 in Houston, Texas.
Children and adults (age range, 11-55 years) with eosinophilic esophagitis and dysphagia were enrolled in the double-blind placebo-controlled trial (ClinicalTrials.gov Identifier: NCT02605837). During a 12-week treatment period, patients received either twice-daily budesonide 2.0 mg (n=213) or placebo (n=105). The coprimary efficacy end point in the study was a ≥30% reduction in the Dysphagia Symptoms Questionnaire (DSQ) combined score at the end of 12 weeks.
A significantly higher percentage of dysphagia symptom responders was observed in the budesonide group compared with the placebo group at 12 weeks (52.6% vs 39.1%, respectively; P =.024). In addition, there was a greater decrease in the mean DSQ score from baseline to 12 weeks in patients treated with budesonide relative to placebo-treated patients (30.3 vs 30.4 [baseline] to 19.5 vs 22.6 [week 12], respectively).
There were also significantly greater improvements in the mean DSQ score in the budesonide group vs placebo group from baseline to week 4 (-8.0 vs -4.0; P =.002), week 8 (-10.7 vs -6.0; P =.001), and week 12 (-13.0 vs -9.1; P =.015). There were few severe or serious treatment-emergent adverse events in either group.
There is an ongoing maintenance study examining the long-term response of budesonide in this patient population (ClinicalTrials.gov Identifier: NCT02736409).
