    ClinicalTrials.gov ID: NCT02605837

  • Objective

    To demonstrate in a placebo-controlled trial that:
    · OBS induces a histologic response (eosinophilic count ≤6/high-powered field [HPF]) in adolescent and adult subjects with eosinophilic esophagitis (EoE) over a 12-week course of therapy.
    · OBS reduces dysphagia, as measured by the Dysphagia Symptom Questionnaire (DSQ), by at least 30% from baseline in adolescent and adult subjects with EoE over a 12-week course of therapy.

  • Key Eligibility

    1) Subject has histologic evidence of EoE with a peak eosinophil count of ≥15/HPF, from 2 of 3 (proximal, mid-, and/or distal) levels of the esophagus at the screening endoscopy.
    2) Subject has a history of clinical symptoms of esophageal dysfunction (e.g., eating problems, abdominal pain, heartburn, dysphagia, vomiting, food impaction, weight loss) intermittently or continuously at screening (Visit -1).
    3) Subject must have experienced dysphagia on a minimum of 4 days in any 2 consecutive weeks of the screening period and in the last 2 weeks prior to the baseline visit (Visit 1).
    4) Subject must not have PPI-responsive EoE based on esophageal biopsies performed after the patient has been on at least 8 weeks of high-dose PPI therapy.
