Trial summary

Based on our hypothesis that orally administered GOS will be fermented into a SCFA pattern high in acetate and that this will lead to beneficial effects on human substrate and energy metabolism, we aim to address the following primary objective: To investigate the effects of a 12-week supplementation of GOS on… Read more about this study

About this study

Official title: The Effects of Galactooligosaccharide (GOS) on Peripheral Insulin Sensitivity and Body Weight Control in Obese Adults With Impaired Glucose Homeostasis

Based on our hypothesis that orally administered GOS will be fermented into a SCFA pattern high in acetate and that this will lead to beneficial effects on human substrate and energy metabolism, we aim to address the following primary objective:

To investigate the effects of a 12-week supplementation of GOS on peripheral insulin sensitivity and body weight control in obese adults with impaired glucose homeostasis.

Being tested
Galactooligosaccharide, maltodextrin
Keywords
Insulin Sensitivity
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GalactooligosaccharideDietary supplement

    The dietary fiber GOS will be supplemented in powder form to regular daily food intake three times per day for 12 weeks

  • maltodextrinDietary supplement

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. systemic insulin sensitivity

    Measured: change from baseline at 12 week supplementation

Secondary outcomes (5)
  1. substrate oxidation and energy expenditure

    Measured: change from baseline at 12 week supplementation

  2. plasma markers of substrate and energy metabolism

    Measured: change from baseline at week 1 and at 12 week supplementation

  3. fecal and plasma SCFA concentrations

    Measured: change from baseline at week 1 and at 12 week supplementation

  4. fecal microbiota composition

    Measured: change from baseline at week 1 and at 12 week supplementation

  5. skeletal muscle and adipose tissue gen and protein expression

    Measured: change from baseline at week 1 and at 12 week supplementation

Questions about this trial

What is this clinical trial studying?

A study testing Galactooligosaccharide and maltodextrin in people with Obesity and Type 2 Diabetes Mellitus, run by Maastricht University Medical Center at 1 site in Netherlands.

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 2 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 10 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 Netherlands. 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?

systemic insulin sensitivity (time frame: change from baseline at 12 week supplementation). 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 NCT02271776, 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 10 Apr 2018.
