Gluten Challenge in Celiac Disease

Study Purpose

Up till 30 participants with celiac disease on a glutenfree diet are asked to consume gluten containing cookies or bread for 3 days. Questionnaires and sampling of blood is done before, during and after.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

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 - 80 Years

Trial Details

Trial ID:

This trial id was obtained from, 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.

Additional Details

Before and 6 days after start of gluten challenge, blood samples will be collected and analysed by using HLA-tetramers to identify and purify CD4+ gluten-specific T cells by flow cytometry. T cells will undergo transcriptome analysis to get an insight in signalling of antigen-specific cells. Other cell populations like CD8+ T cells and γδ T cells will also be analyzed by flow cytometry.

Arms & Interventions


Experimental: Participants

Participants are subjected to gluten intervention in an unblinded fashion.
