Assessment of Immune Activation and Tolerance in Celiac Disease
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.
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 75 Years|
Inclusion Criteria:1. Be a non-smoker who has not used tobacco- or nicotine-containing products (example, nicotine patch) for at least 6 months before Day 1 gluten administration. 2. Have well-controlled biopsy-proven CeD, compliant with a gluten-free diet (GFD) for greater than or equal to (>=) 6 months preceding screening, with resolution of CeD symptoms, normalization of CeD serology, and in the judgment of the investigator, have inactive or minimally-active disease. 3. Be HLA-DQ2.5 and/or HLA-DQ8 positive, assessed at screening. If participants have already been genotyped, results from previous testing may be used in lieu of genotyping at screening. 4. Be willing to delay a planned procedure involving the use of powerful electromagnetic fields (example, magnetic resonance imaging), until the PillCam SB 3 capsule is excreted. 5. Not undergo VCE or optical coherence tomography (OCT) if has an implanted electromedical device or a swallowing disorder. 6. Not undergo OCT if has a contraindication to the device or procedure as per reference information.
Exclusion Criteria:1. Had major surgery and/or donated or lost 1 unit of blood (approximately 500 milliliter [mL]) within 8 weeks before the first dose of gluten. 2. Are unable to refrain from or anticipate the use of any unapproved medication, including prescription drugs, nonprescription drugs, and herbal remedies, beginning approximately 7 days before administration of the initial dose of gluten and continuing throughout the trial until the follow-up visit. 3. Consume excessive amounts of coffee, tea, cola, energy drinks, or other caffeinated beverages per day. An excessive amount is defined as greater than 6 servings (1 serving is approximately equivalent to 120 mg of caffeine). 4. Have positive IgA anti-tissue transglutaminase (tTG), IgA anti-deamidated gliadin peptide (DGP), and IgG DGP serologies at Screening. 5. Have inflammatory gastrointestinal disorders or autoimmune diseases other than CeD or autoimmune thyroid disease. 6. Have known or suspected gastrointestinal obstructions, strictures, or fistulas based on the clinical picture or pre-procedure testing and profile of the PillCam SB 3 capsule. 7. Endoscopy and intestinal biopsy are contraindicated.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
Gluten challenge studies are used to test the effectiveness of therapies designed to prevent immune response to gluten in participants with CeD. The study will enroll approximately 20 participants. Participants will be randomly assigned (by chance, like flipping a coin) in a 1:1 ratio to one of the two treatment groups:
- - Group A: Gluten 3 gm - Group B: Gluten 10 gm All participants will be asked to take an oral dose of gluten at the same time on Days 1 to 14 throughout the study.
