What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
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 Results may not be published yet.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.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether an ancient type of wheat (Triticum monococcum) causes fewer stomach and other symptoms than modern wheat in people with non-celiac wheat sensitivity. Sixty-eight adults who follow a wheat-free diet will eat both types of wheat in a blinded crossover design. Researchers will track symptoms, quality of life, and look for blood markers that could help diagnose the condition.

What this could mean

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

Active substance
Triticum monococcum flour (an ancient type of wheat)
What this could lead to
If this ancient wheat is better tolerated, it could offer a dietary option for people with non-celiac wheat sensitivity and help identify blood markers for diagnosis.
What could go wrong
This is a small, early-stage study (68 people) testing short-term exposure only. Results may not apply to everyone, and participants could still react to the ancient wheat.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 68 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Nov 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * age \>18 and \<65 years; * negativity of class A (IgA) and G (IgG) immunoglobulin (Ig) anti-deamidated gliadin (anti-DGP); negativity of IgA and IgG anti-tissue transglutaminase (anti-tTG) and anti-endomysial antibodies (EMA) ; * absence of intestinal villous atrophy, documented in all patients carrying the DQ2 and/or DQ8 human leukocyte antigen haplotypes (therefore regardless of the negativity of celiac disease-specific serum antibodies); * absence of wheat allergy (negative prick test and/or serum IgE measurement specific to wheat, gluten and gliadin). Exclusion Criteria: * age \<18 and \>65 years; * self-exclusion of gluten/wheat from the diet and refusal to reintroduce it, for diagnostic purposes, before entering the study; * pregnancy; * alcohol and/or drugs abuse; * Helicobacter pylori and other bacterial and/or parasitic infections; * diagnosis of chronic inflammatory intestinal diseases and other organic pathologies affecting the digestive system (for example, serious liver diseases), nervous system diseases, major psychiatric disorders, immunological deficits and impairments that limit physical activity; * cancer * patients undergoing chemotherapy and/or radiotherapy.
