Eosinophils play a key role in the pathogenesis of eosinophilic oesophagitis. Therapies that suppress eosinophil recruitment and activation may give a benefit. Mepolizumab is a humanised monoclonal antibody against interleukin-5 (IL-5). This study will evaluate the ability of mepolizumab to decrease the recruitment and infiltration of eosinophils into the oesophagus, thereby reducing the inflammation and symptoms of EE (eosinophilic oesophagitis) in adult patients.
A Randomised, Double-Blind, Placebo-Controlled, Single-Centre Study to Provide a Preliminary Evaluation of Pharmacokinetics, Pharmacodynamics, Safety and Tolerability of Intravenous Anti-human Interleukin-5 (Mepolizumab, 750mg and 1500mg) in the Treatment of Eosinophilic Oesophagitis in Adults
