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 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 is to learn how well efinopegdutide works compared to placebo in people who have non-alcoholic steatohepatitis (NASH). Researchers will also learn about the safety and benefit of efinopegdutide and how well people tolerate the medicine. The main goal of the study is to compare how many people taking efinopegdutide or placebo stop showing evidence of NASH without liver scarring getting worse.

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 main aim of this study is to learn if fazirsiran reduces liver scarring (fibrosis) compared to placebo. Other aims are to learn if fazirsiran slows down the disease worsening in the liver, to get information on how fazirsiran affects the body (called pharmacodynamics), to learn if fazirsiran reduces other liver injury (inflammation) and the abnormal Z-AAT protein in the liver, to get information on how the body processes fazirsiran (called pharmacokinetics), to test how well fazirsiran works compared with a placebo in improving measures of liver scarring including imaging and liver biomarkers (substances in the blood that the body normally makes and help show if liver function is improving, staying the same, or getting worse) as well as to check for side effects in participants treated with fazirsiran compared with those who received placebo.

Participants will either receive fazirsiran or placebo. Liver biopsies, a way of collecting a small tissue sample from the liver, will be taken twice during this study.

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).
