121 Clinical Trials for Various Conditions
This study aims to investigate how knowledge of gluten immunogenic peptide (GIP) levels in stool and urine affects subsequent adherence to a gluten-free diet. Half of the participants will receive results in real-time using a home device and the other half will store samples to be tested at the end of the 30 week study. Participants will also have a diet review with a dietitian at the beginning of the end of their study and be asked questions about their symptoms, gluten-free diet adherence and quality of life.
Background: - Celiac disease is a condition where the immune system attacks the cells of the small intestine. The intestine becomes inflamed and cannot digest food properly. The disease most often causes a reaction to foods that contain gluten. Most people can treat celiac disease with a gluten-free diet. However, some people have digestion problems even on a gluten-free diet. Researchers want to try a new antibody therapy for celiac disease. The treatment may block the immune reaction that causes the disease. They will test this antibody in people who have celiac disease that has not responded to a gluten-free diet. Objectives: - To see if antibody therapy is a safe and effective treatment for celiac disease that has not responded to standard treatments. Eligibility: - Individuals at least 18 years of age who have been on a gluten-free diet for 6 to 12 months but still have symptoms of celiac disease. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be collected. These samples will help determine if the specific antibody treatment is likely to work. * Before the start of the study, participants will have a biopsy of the small intestine. * Participants will receive three doses of the study antibody as injections. These doses will be given 3 weeks apart. * Treatment will be monitored with blood tests and heart function tests. Participants will also have a second small intestine biopsy within a week after the last dose of the antibody.
The purpose of this study is to determine how well capsule endoscopy identifies changes in the small bowel mucosa of celiac disease patients.
A randomized, double-blind, placebo-controlled clinical study in human leukocyte antigen (HLA)-DQ 2.5+ adults with celiac disease (CeD).
Non-celiac gluten sensitivity (NCGS) is an emerging clinical entity defined as the presence of intestinal and/or extraintestinal symptoms induced by the ingestion or gluten and relieved by a gluten free diet (GFD) in patients without celiac disease or wheat allergy. The pathologic mechanism of the disorder is unknown, and there are no known biomarkers or associated histopathologic findings. In this prospective, randomized controlled trail, we are investigating the utility of patient reported symptom questionnaires, as well as stool gluten and urine quantification tools in patients with NCGS and healthy controls.
This study will assess the effect of gluten on gut barrier function. Investigators at the Mayo Clinic have developed a new gut permeability test using rhamnose (sugar \& water solution), and are hoping to prove its effectiveness in a clinical setting.
The main purpose of this study is to see how cells taken from the lining of the intestine behave in the laboratory with exposure to gluten and other substances that act on the immune system. The cells lining the intestine of a person with celiac disease should be different than a person without celiac disease. The study doctors would like to see how the cells react after coming in contact with gluten and if substances that act on the immune system can prevent gluten related inflammation. Examples of these substances include steroids. The cells should produce chemicals of their own in response to the gluten. These other chemicals will be measured and the results compared between those with: * celiac disease that does not respond to a gluten-free diet (refractory celiac disease) * celiac disease which is controlled by a gluten-free diet * uncontrolled celiac disease (either newly diagnosed with celiac disease or not on a gluten-free diet * gluten-sensitivity * disorders other than celiac disease.
The idea is to evaluate if the so called "Gluten Sensitivity" is a real clinical entity. Gluten sensitive (GS) persons are defined as those patients, being neither celiac or allergic to weat, who develop symptoms following gluten consumption. This will be achieved by evaluating a global symptom score in GS patients receiving gluten compared to those receiving placebo (primary end point). Symptoms to be evaluated: gastrointestinal (Gastrointestinal Symptom Rating Scale, GSRS); not-gastrointestinal (specifically built evaluation scale); VQV scale, built to evaluate quality of life. Gluten or placebo will be administered daily (10 g) for 15 days; for the 15 days before and 15 after all patients will stay on Gluten Free Diet (GFD). Besides clinical evaluation (each week for 6 weeks), intestinal permeability testing and blood sampling will be requested for the identification of possible markers (serological, gut barrier function, immunological and expression of tight junctions constitutive proteins) that may be of help to differentiate the condition of gluten sensitivity (GS) from that of Celiac Disease (CD)(secondary end point). Inclusion and exclusion criteria for patients enrolling are strictly dependant on the given "Gluten sensitivity" definition. We expect to experience a worsening of gastrointestinal and extra-gastrointestinal symptoms, from hours to days, with an increase in the overall symptom score, above the cut off, in at least 45% of GS subjects enrolled and that have received gluten compared to GS who received placebo.
The investigators propose to plan for a multi-center randomized controlled trial (M-RCT) to test the effectiveness of novel gluten detection technologies as an adjunct to telemedicine to manage celiac disease in newly diagnosed adults. If successful, the proposed intervention will improve mucosal recovery, promote a shift in current practice of celiac disease management toward long-term monitoring, and represent a significant step toward reducing the severe physical and psychological consequences of celiac disease.
The study goal is to evaluate the efficacy, safety, and tolerability of KAN-101 in participants with Celiac Disease (CeD)
This is a decentralized study to primarily explore a novel objective digital biomarker (i.e., Gluten Dependency Index) for celiac disease-related responses triggered by gluten exposure using a wearable biosensor. This study also explores a novel objective blood biomarker specific to celiac disease activity and evaluates participant symptoms, lifestyle and an objective comprehensive measurement (e.g., activity, stress and sleep) in celiac disease participants. Approximately 170 well-controlled celiac disease participants (Cohort A) and 40 celiac disease participants with persistent symptoms (Cohort B) will be monitored for 13 and 8 weeks in the observation period, respectively, in a home-based setting using the wearable biosensor along with a mobile platform including some electronic questionnaires. The wearable biosensor continuously records biosensor data. These data will be used to develop a new algorithm for Gluten Dependency Index and calculate the Gluten Dependency Index, Activity Value, Stress Value, or Sleep Time. Participants will report celiac disease-related symptoms, diet (including any accidental gluten exposures), exercise, menstruation questionnaires in CDSD and mobile platform questionnaire (MPFQ), which is originally designed by the Sponsor. All participants both in Cohort A and B are required to maintain gluten-free diet throughout the study. Only participant who are enrolled in Cohort A will be required gluten challenge.
The purpose of this clinical study is to learn more about celiac disease pathogenesis and clinical symptoms. In particular, this study will examine the interactions between biological factors such as, intestinal epithelial cells, microbiota, immune system, genetics, and gluten and their effect on celiac disease clinical symptoms, and severity of tissue destruction and its ability to heal in individuals with celiac disease. Information collected in the study will help researchers to generate better resources to advance celiac disease patient care.
Subjects include: aged 18 to 75 years, inclusive, have biopsy-confirmed disease that is clinically inactive as determined by negative celiac disease (CeD) serology and histology (determined via endoscopy at time of screening), have followed a gluten-free diet (GFD) for ≥6 months as reported by the subject, and be human leukocyte antigen (HLA)-DQ2.5 and/or HLA-DQ8 positive. Study involves the following randomized intervention; 10g gluten + 200mg of Ritlecitinib or placebo
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 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.
The goal of this study is to better understand the symptoms and impacts of celiac disease (CeD). Participants use a smart phone online app to answer daily questionnaires about symptoms and life with CeD for 12 weeks. There are no blood draws, gluten challenges, medications, or doctor visits required.
The CASCADE Study (Combined Antibody Screening for Celiac and Diabetes Evaluation) is an observational study whose primary goal is to show that population-based screening for advanced prediction of type 1 diabetes (T1D) and celiac disease (CD) is feasible to prevent diabetic ketoacidosis (DKA), improve celiac disease diagnosis, and ultimately gain public health acceptance to facilitate future prevention. It has two arms, a Birth Cohort and a Kids (cross sectional) Cohort.
The primary objectives are: * Characterize the T cell receptor (TCR) repertoire in duodenal biopsy samples of participants pre- and post-challenge. * Compare for each patient the TCR repertoire of duodenal biopsy samples with the peripheral blood TCR repertoire of each study participant * Characterize the transcriptome of duodenal biopsy samples and blood from study participants pre- and post-challenge The secondary objectives are: * Ex vivo identification and validation of DQ-restricted gliadin specific TCRs. * Characterize the gluten-challenge induced changes in small intestine histology using standard for Celiac Disease (CeD) histological assessments
The main aim of the study is to assess if TAK-101 can reduce gluten related symptoms and immune activation in adult participants with celiac disease (CeD) on a gluten-free diet (GFD). Participants will receive TAK-101 and/or placebo through the vein on Day 1 and Day 8. All participants will receive active treatment at Week 24.
This study will evaluate the efficacy and safety of PRV-015 in adult patients with non-responsive celiac disease (NRCD) who are on a gluten-free diet (GFD).
This is a gluten challenge study to characterize peripheral blood and intestinal gluten specific cluster of differentiation 4 glycoprotein (CD4+) thymus lymphocyte (T cell) subsets in participants with Celiac Disease
This is a model development, open label, no therapeutic treatment, three sequential group, short term-gluten challenge study in subjects with celiac disease. Immune responses are evaluated following gluten challenge. Approximately fifteen subjects with celiac disease will be enrolled in up to three sequential groups (5 subjects per group).
This study is to characterize the safety and tolerability of an investigational drug called TIMP-GLIA when either one or two intravenous doses are given to subjects with celiac disease. The way the body reacts to TIMP-GLIA is being checked by laboratory tests of the blood and urine, and study subject health will also be monitored by vital signs such as blood pressure, electrocardiogram (ECG), and physical examination.
The primary purpose of this study is to characterize changes in gluten-specific T cells and pathology in the small intestine with specific focus on biomarkers likely to change with therapeutic celiac disease (CeD) treatment.
The current treatment for celiac disease is a strict 100% gluten free diet. Little is known about the best way to promote adherence to such a strict diet and how to maximize quality of life at the same time. This pilot will look at the utility of a new innovation to promote gluten free diet adherence - a portable gluten sensor device. Participants will be 30 teenagers and adults with celiac disease recruited from the Celiac Disease Center at Columbia University in New York City. Before and after the intervention, participants will be asked about their adherence to a gluten free diet, quality of life, symptoms, and feelings of anxiety, and depression. This pilot data will help to inform interventions that the investigators hope to test in a larger NIH-funded trial to better understand the best ways to promote adherence and quality of life in celiac patients.
This is a clinical trial to evaluate the sensitivity of noninvasive, novel markers of gluten ingestion in celiac disease patients who are following gluten free diet for at least a period of one year. These noninvasive markers may be helpful to monitor the silent intestinal damage, possibly resulting from the accidental consumption of gluten due to cross contamination of gluten free diet.
Celiac disease (CD) is a complex disease caused by eating gluten, a protein contained in wheat, rye, and barley. It is well known that many factors contribute to the development of CD, including the genes that you have and the foods that you eat. In the CDGEMM study, we will consider as many of these factors as possible and study how they each contribute to disease development. If the investigators find that any one factor, or combination of factors, increases the risk of developing CD, we will be able to apply this information and help prevent or detect disease in high-risk children in the future.
To determine the effects of 12 weeks administration of different dose levels of ALV003 on the mucosal lining of the small intestine and symptoms in celiac disease patients.
The purpose of this study is to see if it makes sense to test people for celiac disease who have a first or second degree relative (parent, sibling, child, grandparent, aunt or uncle) with celiac disease. The investigators will check to see what differences there are in the health and quality of life between those who know they have celiac disease and start the gluten free diet and those who do not.
The specific hypotheses are: Gluten supplementation for four weeks increases small intestinal permeability and accelerates colonic transit in patients with irritable bowel syndrome with diarrhea (IBS-D) or functional diarrhea (FD) who are HLA-DQ2 positive.
