About this study

Official title: Effect of Oligofructose Versus Placebo on Body Weight and Satiety Hormone Secretion in Overweight and Obese Adults.

The purpose of this study is to determine if oligofructose supplementation promotes weight loss in overweight and obese adults.

Read the detailed description

Obesity is a primary health concern for many western countries as it is linked to several chronic diseases as well as, large health care costs. Although obesity is a multifactorial disease, it is known that levels of satiety hormones including glucagon like peptide-1 (GLP-1) and peptide YY (PYY) are reduced in obesity. The ability of prebiotic fiber to promote weight loss through the production of satiety hormones has been tested previously using rodents. Here it was found that prebiotic supplementation resulted in a decreased energy intake, higher GLP-1 levels in the plasma and increased proglucagon mRNA levels in the gut. This study will address the important question of whether prebiotic fiber supplementation is effective in reducing body weight in overweight or obese human subjects.

Questions about this trial

What is this clinical trial studying?

A study testing Oligofructose in people with Obesity, run by University of Calgary at 1 site in Canada.

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 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 23 May 2008. 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 Canada. 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?

Body weight (time frame: 3 months). 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 NCT00522353, which also lists 2 linked publications.

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?
