About
An open-label, dose-escalation study to explore the safety, tolerability and pharmacokinetics of EP-104IAR in adults with eosinophilic esophagitis (EoE). Endoscopic and histologic assessments will also be evaluated to understand the local effects of EP-104IAR on eosinophilic EoE disease activity.
Approximately 27 to 33 participants will be enrolled in dose escalation: 3-6 participants per dose cohort in approximately 9 cohorts. The number of participants enrolled in escalation will depend on the number of dose escalation cohorts evaluated, and dose cohorts needing to be expanded.
An additional 10-24 participants will be enrolled in 1 or 2 cohorts of 10-12 participants each at tolerable dose regimen(s) selected based on the accumulated clinical data to identify the recommended phase 2 dose(s) (RP2D).
The study involves 8-10 site visits spread over approximately 24-52 weeks.
All participants will receive active study drug (EP-104IAR), The study drug will be administered by qualified personnel during an esophagogastroduodenoscopy (EGD) procedure at the Baseline/Dosing visit.
Safety will be assessed throughout the study. Blood and urine samples will be collected at site visits for laboratory assessments and to measure plasma levels of EP-104IAR.
Participants will complete questionnaires to assess symptoms of dysphagia and odynophagia and will undergo 3-4 EGDs with esophageal biopsies at the Baseline/Dosing Visit, at 4, 12 and 36 weeks post dose.
