Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how people with celiac disease react to gluten in liquid form (a shake) versus solid form (a cookie). Thirty adults on a gluten-free diet will try both, in random order, with blood samples taken to measure immune markers and symptoms. The goal is to see if liquid gluten causes a stronger immune response, which could help improve future testing methods.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Vital wheat gluten (gluten-containing shake and cookie)
What this could lead to
If successful, this could help researchers better understand how the form of gluten affects immune reactions in celiac disease, potentially improving future diagnostic tests.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to everyone. It is designed to measure immune markers, not to test a treatment, so there is no direct benefit for participants.

Inclusion Criteria: * BMI 18-33 kg/m2 * Willingness to comply with the study procedure and having signed informed, written consent * Previous diagnosis of coeliac disease according to established guidelines based on positive serology (Endomysium test, IgA-TG2 and/or IgG-DGP) (diagnosed in childhood) and a duodenal biopsy showing villous atrophy graded as Marsh 3 according to guidelines from European Society for Study of Coeliac Disease . * Strict adherence to a gluten-free diet at least the 12 last months. Exclusion Criteria: * Positive serology (IgA-TG2 below upper level of normal) at screening visit * Pregnancy or breast feeding. Fertile women must use effective contraception. * Other inflammatory disease like uncontrolled hypothyreosis, type 1 diabetes, cardiovascular diseases, thyroid and renal disorders, inflammatory bowel diseases or any other disease that in the opinion of the responsible clinician makes the patient unsuitable for the study * Using of immunosuppressive/steroid medications * Wheat allergy * Severe acute infection
