Small Bowel Ultrasound and Antibody Levels in Celiac Disease Activity

This observational study aims to evaluate the relationship between small bowel ultrasound findings and tissue transglutaminase (tTG) antibody blood levels in assessing celiac disease activity. The traditional gold standard for diagnosing and monitoring celiac disease involves an invasive duodenal biopsy. Researchers want to determine if combining a painless, non-invasive small bowel ultrasound with tTG antibody blood tests can accurately predict disease severity and monitor a patient's response to a gluten-free diet. The study will enroll 140 participants aged 2 years and older, including newly diagnosed patients, patients currently on a gluten-free diet, and a control group. All participants will undergo a clinical assessment, blood tests for tTG antibodies, and a high-resolution small bowel ultrasound. Newly diagnosed patients will also undergo an upper gastrointestinal endoscopy and biopsy to confirm their diagnosis. Researchers will score the ultrasound severity based on factors like bowel wall thickness and compare it to the antibody levels. A cohort of patients will be monitored over time with serial assessments at baseline, 6 months, and 12 months.

This is a Phase 2a/b, randomized, double-blind, placebo-controlled, parallel-group, 6-arm study to evaluate the efficacy and safety of amlitelimab in adult participants with non-responsive celiac disease (NRCD) who are on a gluten free diet (GFD) with and without simulated inadvertent gluten exposure (SIGE). The primary purpose of this study is to demonstrate the efficacy of subcutaneous (SC) amlitelimab in male and female participants (aged 18 to 75 years, inclusive) with NRCD. The study will assess the effect of amlitelimab when compared to placebo on gluten induced changes in the intestinal mucosa as measured by the villous height to crypt depth (Vh:Cd) ratio. The effect of amlitelimab on participant-reported celiac signs and symptoms along with the safety, tolerability, and pharmacokinetics of amlitelimab will also be studied. Study details include: The study duration will be up to 48 weeks (including a 16-week safety follow-up period) with 10 visits for participants who opt not to enter the optional long-term extension. The study duration will be up to 172 weeks (including an 8-week safety follow-up period) with 22 visits for participants who enter the optional long-term extension. The double-blind placebo-controlled treatment duration will be up to 28 weeks.

Information collected in the study will help researchers to generate better resources to advance celiac disease patient care.

Hydroxyapatite-Based Home Treatment for Dentin Sensitivity in Celiac Patients

This single-center, randomized controlled clinical trial aims to evaluate the effectiveness of a home-based treatment using hydroxyapatite-based oral care products in adult patients with celiac disease who exhibit enamel demineralization and dentin hypersensitivity. Forty patients will be enrolled and randomly allocated into two parallel groups. The control group will perform home oral hygiene using only a hydroxyapatite-based toothpaste (Biorepair® Total Protection) twice daily. The trial group will follow the same regimen with the toothpaste, but will also apply a hydroxyapatite mousse (Biorepair® Plus Intensive Enamel Repair) once every evening before bedtime throughout the study period. The primary objective is to assess the reduction in dentin hypersensitivity using the Schiff Air Index. Secondary outcomes include changes in plaque accumulation (Plaque Index), gingival bleeding (Bleeding on Probing), pain perception (Visual Analogue Scale), and caries experience (DMFT and DMFS indices). Enamel demineralization will be analyzed through near-infrared transillumination (DIAGNOcam), laser fluorescence (DIAGNOdent), and digital image analysis (ImageJ software). All clinical parameters will be evaluated at baseline and after 1 week, 1 month, 3 months, and 6 months. The study seeks to determine whether the addition of a remineralizing mousse to daily oral care provides superior benefits in reducing sensitivity and improving enamel integrity in patients with celiac disease.

AI System for Detection and Characterization of Chronic Enteropathies

Coeliac disease (CD) is an immune-mediated enteropathy leading to small intestinal mucosal atrophy. Diagnosis relies on serology and duodenal biopsies, but it can be complicated by patchy lesions and differential diagnosis with Non-Celiac Enteropathies (NCEs). This multicenter observational study aims to develop and validate an Artificial Intelligence (AI) system to detect and characterize small bowel mucosal atrophy and other pathological findings using endoscopic imaging. The study involves a retrospective phase for training the AI model and a prospective phase to validate its diagnostic accuracy compared to standard human assessment.

Participants will: * Receive one oral dose of HB-2121 * Attend 4 in-person clinic visits for checkups, lab tests, and monitoring * Complete 2 remote visits that include safety lab assessments * Fill out a short daily questionnaire for 7 days about symptoms and health status

Single-cell Immune Response to Controlled Gluten Ingestion in Pediatric Celiac Disease

This study investigates how the immune system of children with celiac disease responds to controlled, small amounts of gluten. Children on a strict gluten-free diet are randomly assigned to receive either placebo, 50 mg of gluten, or 5 g of gluten once daily for three days, simulating real-life accidental exposure or dietary transgression. Blood samples are collected on Day 1 (before gluten intake) and Day 8 (five days after the last dose). Stool and urine samples are also collected for complementary analyses. Using single-cell ribonucleic acid (RNA) sequencing, T-cell receptor sequencing, microRNA profiling, and exploratory metabolomics, the study aims to characterize changes in immune cell populations and gene expression after gluten exposure. The objective is to determine whether even very small amounts of gluten induce measurable systemic immune responses and whether these responses differ according to the dose administered. Understanding these mechanisms may support the development of new biomarkers and improve clinical management of pediatric celiac disease.

Unhide® Project: A Digital Health Platform to Collect Lifestyle Data for Brain Inflammation Research

The unhide® Project is a non-interventional, longitudinal research study designed to establish a secure data repository of demographic, health, and lifestyle information from individuals with brain inflammation and related neuroinflammatory conditions. Participants in the United States aged 2 years and older will provide self-reported health data, biometrics, and symptom diaries through the MyDataHelps™ app (branded as unhide® for this study). The goal is to create comprehensive longitudinal profiles to facilitate research into disease subtypes, causes, diagnostics, and potential treatments, as well as to identify potential participants for future optional studies. "Healthy" individuals without brain inflammation are also eligible to participate. The digital health research platform used in this study was originally developed and designed by Solve M.E and was called SolveTogether. The Brain Inflammation Collaborative (BIC) expanded upon Solve M.E.'s work to include related diagnoses, pediatric participants, enhance symptom tracking, and more. BIC and Solve M.E. combined Solve Together and unhide®, to create The unhide® Solve Together Unified Platform in 2025.

VTP-1000 in Adults With Celiac Disease

GLU001 is a first-in-human clinical trial to assess the safety and tolerability of VTP-1000 for adults with celiac disease. This trial will assess VTP-1000 at various dose levels compared to placebo in a single ascending dose (SAD) and multiple ascending dose (MAD) format. Participants will be followed for a short period of time to assess the impact of VTP-1000 on their immune system (Adverse events, reactions in the blood, and physical exam differences). Participants enrolled in the MAD portion of the trial will undergo a gluten challenge to assess the impact exposure to gluten has on participants after administration of VTP-1000.

A Biospecimen Collection Study to Identify the Targets of Disease-Reactive T Cells in Patients With Autoimmune Disease

The most clinically meaningful way to discover new targets of T cells in autoimmune diseases is to study the tissues of patients with active autoimmune disease mediated organ inflammation. These tissues contain both cytotoxic and helper T cells that are driving their disease, and these T cells are being guided by TCRs that recognize tissue-specific targets. By collecting tissue when a patient has active inflammation, it is possible to determine which T cells are activated and undergoing clonal expansion in the patient's diseased organ. TScan has developed a genome-wide, high-throughput technology to determine the natural, physiological target of any TCR (Kula, 2019). The goal of this study is to isolate T cells from inflamed tissues and matched blood samples and/or matched normal tissues (for patients with inflammatory bowel diseases). T cell clones that are expanded in diseased tissues relative to blood or normal tissues will be selected and the targets of their TCRs will be defined using TScan's genome-wide, high-throughput target ID technology. The goal of this study is to discover a collection of peptide targets, along with their associated TCRs to be developed as new tolerogenic therapies for patients with autoimmune diseases.

No-biopsy Approach in Celiac Disease: Cut-off Points for IgA Anti-tissue Transglutaminase Assays

The main objective of this multicenter and observational study is to define the optimal threshold of different commercially available IgA anti-transglutaminase (tTG-IgA) antibody assays for celiac disease diagnosis (CD) avoiding the need for an intestinal biopsy. The main questions to be answered are: * Is the anti-tTG-IgA titer cut-off above 10 times the upper limit of normal (ULN) useful in all anti-tTG IgA assays? * Is the diagnostic performance of the newly defined cut-offs of anti-tTG-IgA the same in all the evaluated assays? * Is the dynamic of the anti-tTG-IgA levels after the introduction of the gluten-free diet (GFD) similar across the different assays included in the study? This is a prospective multicenter study that will enroll pediatric and adult patients with new-onset CD during the years 2023 and 2024. Serum from these patients will be collected for the determination of anti-tTG-IgA according to the local methodology (participating hospital) and by the anti-tTG IgA assays most commonly used in our country, which will be centralized in the same reference center (Hospital Universitario La Paz).
