About this study

Official title: Randomized Four-arm Trial Investigating the Effects of Different Food Matrices on the Prebiotic Efficacy of Inulin Type Fructans (ITF) From Chicory Root

The aim of the study is to investigate whether the food matrix has an influence on the prebiotic efficacy (bifidobacteria growth) of chicory-derived Orafti® inulin in healthy adult volunteers. The main question it aims to answer is:

Does the food matrix influence the prebiotic effect of chicory-derived inulin in terms of stimulation of bifidobacteria in the gut microbiota Participants will receive one of three food items containing inulin or pure inulin dissolved in water daily for 10 days. The food items or pure inulin powder will deliver 10 g/d inulin split into two dosages of 5 g/d. They will provide stool samples before and at the end of the intake period. They will record any gastrointestinal sensations and bowel habits in a diary. Urinary samples will be collected at baseline and end of intervention for analysis of metabolites with Nuclear Magnetic resonance (NMR).

    Measured: 10 days

Secondary outcomes (9)
  1. Changes in level of total Bacteria

    Total bacteria will be assessed by fluorescence in situ hybridisation - flow cytometry (FISH-FLOW)

    Measured: 10 days

  2. Changes in gut bacterial composition

    Bacterial numbers will be assessed by fluorescence in situ hybridisation - flow cytometry (FISH-FLOW) and 16S rRNA gene sequencing

    Measured: 10 days

  3. Stool frequency

    Numbers of stools will be recorded in daily diary

    Measured: 10 days

  4. Stool consistency

    Stool consistency will be recorded in daily diary according to Bristol Stool Form Scale

    Measured: 10 days

  5. Bloating

    Bloating will be recorded in daily diary according to a 4-point scale

    Measured: 10 days

  6. Abdominal pressure

    Abdominal pressure will be recorded in daily diary according to a 4-point scale

    Measured: 10 days

  7. Abdominal pain

    Abdominal pain will be recorded in daily diary according to a 4-point scale

    Measured: 10 days

  8. Flatulence

    Flatulence will be recorded in daily diary according to a 4-point scale

    Measured: 10 days

  9. Changes in urinary metabolites

    Urinary metabolites will be analysed by Nuclear magnetic resonance (NMR)

    Measured: 10 days

Questions about this trial

What is this clinical trial studying?

A study testing Inulin in people with Healthy, run by Beneo-Institute at 1 site in United Kingdom.

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 8 inclusion and 12 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 21 Dec 2022. 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 United Kingdom. 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?

Changes in level of Bifidobacterium spp. (time frame: 10 days). It is what the study was designed to measure, not a finding.

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 21 Dec 2022.
