Inclusion criteria

Volunteers with a biopsy confirmed diagnosis of celiac disease
Human leukocyte antigen (HLA) serotype DQ 2.5 and HLA-DQ 8 haplotypes
Maintaining a gluten-free diet for at least one year. Compliance will be assessed by serology, compatible responses to a self-reported assessment of gluten-free diet adherence and the absence of typical celiac disease symptoms
Able to participate and to comply with the study restrictions including the requirements of the gluten challenge

Exclusion criteria

A diagnosis of non-celiac gluten sensitivity
A personal history of food intolerance other than to gluten, or diagnosis of galactosemia, lactose, galactose or fructose intolerance
A personal history of severe acute symptomatic reaction to sporadic gluten ingestion
A diagnosis of refractory celiac disease or presence of severe complications of celiac disease
Diagnosed or suspected immunoglobulin A (IgA) deficiency
Acute inflammatory bowel disease (ulcerative colitis, Crohn's disease), gastrointestinal obstruction or sub-occlusive syndromes, digestive perforation or risk of digestive perforation, painful abdominal syndromes of undetermined cause
A history of stomach or intestinal surgery or resection. Appendectomy and hernia repair are acceptable
Any confirmed significant allergic reactions (urticaria or anaphylaxis) against any drug, or multiple allergies (non-active hay fever is acceptable)
Immunocompromised or with reduced immune function considered to be clinically significant by the Investigator
Immunization within 30 days before the screening visit or planning vaccination during the study
Women who are pregnant or lactating, or who are of child-bearing potential and do not agree to comply with requirements for contraceptive use. Men who do not agree to comply with requirements for contraceptive use and restrictions on sperm donation
