A Trial to Learn if Dupilumab is Safe for and Helps Adult and Adolescent Participants With Eosinophilic...
Eosinophilic GastritisEosinophilic Duodenitis1 moreThe 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, compared to placebo. 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 your 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) Exploratory research to better understand the study drug and EoG with or without EoD and related diseases.
Personalized Risk Estimation for Crohn's Disease (PRE-CD): Implementation and Feasibility
Inflammatory Bowel DiseasesCrohn Disease6 moreThe aim of this study is to develop and assess the feasibility and effect of a web-based, personalized risk-estimation for Crohn's disease (PRE-CD) tool on behaviors and biomarkers associated with risk for Crohn's disease in unaffected first-degree relatives of patients with inflammatory bowel disease. We hypothesize that personalized risk disclosure via the PRE-CD educational tool is both feasible and successful in modifying behaviors associated with Crohn's disease risk and normalizing pre-clinical disease biomarkers when compared to standard Crohn's disease education. Broadly, completion of this project will also help elucidate the role of lifestyle and dietary factors in pre-clinical Crohn's disease development in high-risk individuals, and provide novel insight into potential strategies for disease prevention in this population.

Eosinophilic DuodenitisEosinophilic GastroenteritisThis is a Phase 3, multi-center, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of lirentelimab (AK002) given monthly for 6 doses in adult patients with active eosinophilic duodenitis. Subjects who complete the randomized, double-blind, placebo-controlled treatment may have the option to receive 6 doses of open-label lirentelimab (AK002) through the OLE Period of the study.

Is a Reporting System for Gastritis or Duodenitis (Modified Lanza Scale) Reproducible?
GastritisDuodenitisThe modified Lanza scale (Lanza FL, 1984) has been widely utilized to grade the degree of gastritis and duodenitis. However, the inter-rater or intra-rater reproducibility of this scale has never been validated. As a quality improvement program, it is important to study the reproducibility of the scale between different operators and the operators himself. Method: During upper endoscopic examinations, one investigator performed the procedure and the second investigator look at the endoscopic image. The degree of gastritis and duodenitis is graded. The results of the grading are blinded to the other investigator. The endoscopic video is stored for reassessment to determine the intra-rater reliability. The patient identifier is stored in serial number. The investigator will not retrieve the report of the first assessment during the second assessment.
