Budesonide Versus Fluticasone for Treatment of Eosinophilic Esophagitis

Eosinophilic Esophagitis Clinical Trial

Official title: Budesonide Versus Fluticasone for Treatment of Eosinophilic Esophagitis

Status Completed

Clinical Trial Summary

Purpose: To determine whether oral viscous budesonide (OVB) or fluticasone metered dose inhaler (MDI) most effectively treats EoE by improving histologic findings and symptoms, which medication provides a more durable treatment response, and whether biomarkers can predict treatment response.

Participants: A total of up to 200 16-80 year old patients with a new diagnosis of eosinophilic esophagitis (EoE) who are referred for upper endoscopy will be consented with a target of 122 randomized.

Procedures: This will be a prospective, randomized, double-blind, double-dummy, clinical trial comparing OVB to fluticasone MDI for treatment of EoE. This overall study design will generate data for all three Aims

Clinical Trial Description

This will be a prospective, randomized, double-blind, double-dummy, clinical trial comparing oral viscous budesonide (OVB) to fluticasone metered dose inhaler (MDI) for treatment of EoE. A total of 122 subjects aged 16-80 years old will be randomized in a 1:1 fashion to one of two active treatment arms: OVB + placebo inhaler or fluticasone MDI + placebo slurry.

In the first arm, subjects will be treated with OVB at a dose of 1 mg twice daily, and they will also be instructed to use a placebo inhaler identical to the fluticasone MDI, with instructions to swallow 4 puffs twice daily. The OVB is a slurry equivalent to what is used clinically: 1 mg/4 mL aqueous budesonide mixed with 10 g of sucralose. Rather than asking the subjects to mix the slurry on their own and risk inconsistent formulations, the University of North Carolina (UNC) investigational drug pharmacy (IDP) will provide pre-mixed OVB to all patients. The IDP will also provide placebo inhalers to all patients. The dose for OVB has been chosen because it is the most commonly studied dose, including one prior study led by this Principal Investigator, so we can accurately estimate response rates.

In the second arm, subjects will be treated with fluticasone MDI at a dose of 880 mcg twice daily (4 puffs of a 220 mcg inhaler twice daily), and they will also be instructed to take 4 mL twice daily of a placebo slurry of sucralose identical in consistency and taste to the OVB. The UNC investigational drug pharmacy (IDP) will provide the fluticasone MDIs and pre-mixed placebo slurries to all patients. The dose for fluticasone MDI has been chosen because this is the most commonly used dose in adolescents and adults with EoE, so effect estimates are also available.

For both arms, the slurry will be administered first, the MDI will be administered 15 minutes later, and patients will take nothing by mouth for an additional 30 minutes.

Subjects will receive 8 weeks of treatment and will then be monitored for up to 52 weeks for recurrence of symptoms. ;
