About this study

The aim of this study is to demonstrate the beneficial effects on gut microbiota composition and activity of the diary intake of insoluble fiber (extract from Aspergillus Niger) for three weeks. The first studies about the fiber have shown a favorable gut microbiota modulation and an improvement of metabolic parameters like LDL cholesterol. In addition to fecal measurements, several biomarkers of colic fermentation will be assessed: expired gases, PolyUnsaturated Fatty Acid, Short Chain Fatty Acid (SCFA) after a rich-fiber breakfast (= 15 grams) and a nutritional challenge test at lunch. The gastrointestinal tolerance of fiber intake and the intestinal transit modification will be also followed during all the study.

Questions about this trial

What is this clinical trial studying?

A study testing Kiotransine (chitin-glucan from aspergillus niger) in people with Cardiometabolic Risk and Abdominal Obesity, run by Hospices Civils de Lyon at 1 site in France.

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 5 inclusion and 7 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 15 Sep 2025. 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 France. 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. Some participants in this study may receive a placebo. 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?

Fecal SCFA (time frame: baseline and three weeks). 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 NCT03773900, 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 15 Sep 2025.
