About this study

The aim of this research study is to characterize the fermentation of chitin-glucan fiber by assessing the volatile compounds released in the breath. For this purpose, an interventional study with control will be performed. After a single administration of 4.5 g of chitin-glucan fiber, the kinetic of production of exhaled volatile compounds (such as H2, methane, SCFAs,…) will be measured during twelve hours. These results will be compared to the exhaled volatile compounds measured during twelve hours after supplementation with 4.5g of maltodextrin (placebo).

Questions about this trial

What is this clinical trial studying?

A study testing Chitin-glucan and Maltodextrin in people with Healthy, run by Université Catholique de Louvain at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. 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?

Exhaled acetate (time frame: Before product ingestion (baseline) and 30 minutes, 2 hours, 4 hours, 5 hours, 6 hours, 8 hours, 10 hours and 12 hours after product ingestion). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03494491, which also lists 1 linked publication.

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 11 Apr 2018.
