4 Clinical Trials for Various Conditions
This study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of intravenous mepolizumab in pediatric subjects with eosinophilic esophagitis.
This is parallel, Phase 4 study which consists of a 24 week (0.5 years) randomized, double blind, placebo controlled, 2-arm treatment period followed by an open label segment of 104 weeks (2 years) for a total of 128 weeks (2.5 years) to evaluate the effect of dupilumab treatment on esophageal function, and remodeling in adults with eosinophilic esophagitis. Duration of study period (per participant) * Screening period: Up to 12 weeks before Week 0 * Randomized double-blind period: 24 weeks * Open label period: 104 weeks * Post Investigational Medicinal Product (IMP) intervention follow-up period: up to 12 weeks or until the participants switch to commercialized dupilumab, whatever comes first. There will be ten (10) site visits, and five (5) direct-to-participant IMP delivery visits (except if prohibited by local regulatory authorities or if participant is not willing. In this case, IMP will be dispensed at the study site).
The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for active eosinophilic esophagitis (EoE) in adult participants.
This study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE). Upon study enrollment, the participant will begin a proton pump inhibitor (PPI), Omeprazole 20mg twice daily. After taking Omeprazole for four weeks, the participant will have a Transnasal Endoscopy, and biopsies will be taken to determine the histological change. If the biopsies are abnormal, the participant continues Omeprazole and will undergo another endoscopy at eight weeks. The study aims to determine the percentage of children with Eosinophilic Esophagitis who improve with PPI use and to determine the length of time and effectiveness of PPI therapy in the management of EoE. The investigators hypothesize that following the initiation of PPI for treatment of Eosinophilic Esophagitis, biopsies obtained will show decreasing eosinophil counts at four weeks, which is sooner than the previously reported eight-week period.
