The 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)

The purpose of this study is to assess the efficacy and safety of barzolvolimab in adult Eosinophilic Esophagitis patients.

The purpose of this study to evaluate the potential for disease-mediated drug-drug interactions between cendakimab and selected substrates of metabolic enzymes in eosinophilic esophagitis participants.

This is a multicenter, randomized, placebo controlled study to evaluate the efficacy and safety of ABX464 given at 25 or 50 mg QD in inducing clinical remission in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors].

This study is to evaluate the Pharmacodynamic (PD), safety, tolerability, Pharmacokinetic (PK), and plasma biomarker response of KAN-101 in participants with Celiac Disease (CeD).

The purpose of this study is to evaluate the effectiveness and safety of ozanimod (RPC1063) in achieving and maintaining clinical remission. Ozanimod will be administered orally to pediatric participants with moderate to severe active ulcerative colitis (UC) who have had an inadequate response to conventional therapy.

The primary objective is to characterize the efficacy TEV-48574 in adult participants with IBD (moderate to severe Ulcerative Colitis (UC) or Crohn's Disease (CD)) as assessed by induction of clinical remission (UC) and endoscopic response (CD) at week 14. Secondary objectives: - To evaluate the efficacy and dose response of the 2 different dose regimens as assessed by multiple standard measures - To evaluate the safety and tolerability of the 2 different dose regimens - To evaluate the immunogenicity of the 2 different dose regimens The study will consist of a screening period of up to 6 weeks (42 days), a 14-week treatment period, and a 4-week follow-up period.

A randomized, double-blind, placebo-controlled multicenter, phase 3 study to evaluate the efficacy and safety of tezepelumab administered subcutaneously (SC) using an accessorized pre-filled syringe (APFS) versus placebo in adult and adolescent patients with eosinophilic esophagitis (EoE).

This is a study to learn if the experimental medicine (called PF-07054894) is safe, effective, and how it is processed in adult people with ulcers in the colon.

The main aim is to see how TAK-062 works to reduce celiac-related symptoms and improve small intestinal damage due to gluten exposure, in participants with celiac disease (CeD) attempting to maintain a gluten-free diet (GFD) in treated participants versus placebo controls.
