Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

40 participants with Eosinophilic Gastritis 12-70 years of age will be randomly assigned with dupilumab or placebo subcutaneous injections every two weeks for a total of 12 weeks. Study subjects who complete the 12-week treatment phase, may continue into an open label extension study, where dupilumab will be administered every two weeks for a total of 24 weeks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a phase 2, multi-center, randomized, double-blind, placebo-controlled trial testing the efficacy of dupilumab vs. placebo in EG. Qualifying subjects will be randomized 1:1 to either study drug (dupilumab) or placebo, and will receive 600 mg once followed by 300 mg doses every two weeks of study treatment for a total of 6 injections. After the 6th injection subjects may continue into an open-label treatment phase in which dupilumab will be administered every two weeks for a total of 24 weeks.

Approximately 14 sites associated with the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) will take part in the study.

The primary objective of this study is to assess the efficacy of repeat subcutaneous (SC) doses of dupilumab, compared with placebo, to reduce eosinophilic inflammation in the gastrointestinal tract of patients with EG.
