About this study
Official title: GlutDigest - Enzymes-assisted Gluten Digestion (Pilot Study)
This is a pilot, feasibility study to evaluate, test and optimize sample analysis procedures and protocols before the full-scale, crossover study is conducted.
Read the detailed description
Two important factors can influence the proportions of gluten and starch that resist digestion: (1) enzyme availability and specificity and (2) the structural properties of the food. A complete evaluation of gluten digestion and of the impact of dietary supplements is difficult to conduct because it is not easy to obtain samples of digestive chime. The analysis of the ileal effluent of healthy ileostomy patients constitutes a non-invasive alternative to intubation techniques for the study of nutrient digestion and of the fate of probiotics in the small intestine.
The main aim of this study is to test and optimize sample analysis protocols before conducting the full-scale, crossover study which will aim at evaluating the impact of two dietary supplements (Glutalytic® and DE111®) and of oatmeal properties on the digestion of gluten and starch and on the glycemic response.

What is being measured
The primary outcome is the main question the study is designed to answer.
Undigested wheat protein after each treatment
Difference between the mean concentration of undigested wheat protein in ileal effluent samples.
Measured: 9-hour period after the test meal
Secondary outcomes (4)
Vegetative DE111 cells
Mean concentration of DE111® cells recovered in the ileal effluent samples.
Measured: 9-hour period after the test meal
Glycemic response
Difference between the mean area under the glucose concentration (measured in the interstitial fluid) curves following each treatment.
Measured: At baseline, and at different time-points in the 9-hour period after consumption of the test meal.
Undigested starch
Difference between the mean concentration of undigested starch in ileal effluent samples.
Measured: 9-hour period after the test meal
Undigested food particles
Pictures of undigested foods particles and microscopy will be combined for a combined assessment of macro- and micro- structural characteristics of the food particles recovered in ileal effluent samples.
Measured: 9-hour period after the test meal

Where is the study taking place?
The record lists 1 site in Ireland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Oct 2020; AzTrials last refreshed its copy on 29 Oct 2026.
