About this study

This study is researching an experimental drug called dupilumab. The study is focused on participants with active eosinophilic gastritis (EoG) with or without eosinophilic duodenitis (EoD). Participants with EoD only are not eligible for enrollment. EoG and EoD are uncommon, persistent, allergic/immune diseases in which eosinophils (a type of white blood cell) gather in large numbers in the stomach and small intestine and cause inflammation and damage. The aim of the study is to evaluate the effect of dupilumab on relieving EoG (with or without EoD) symptoms and reducing inflammation in the stomach and, if applicable, small intestine in adults and adolescents aged 12 years and older after at least 24 weeks (about 6 months) and up to 52 weeks (1 year) of treatment. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
