About this study

Official title: Evaluation of Changes in Gut Transit Time and Gastrointestinal Symptoms Following the Consumption of a Fiber Containing Product in Adults With Constipation

Gastrointestinal discomfort regularly affects >25% of the population worldwide. One of the major contributors to GI discomfort is constipation, which has a prevalence of ~15% and symptoms of which have a significant negative impact on the sufferer's quality of life. One of the hallmarks of chronic constipation is slow progression of contents through the gut (i.e. slow gut / colonic transit time), which may be associated with hard stools that are difficult to expel.

Dietary fiber supplements are widely used as a first-line treatment for constipation although little Level 1 evidence exists to support its use in adults. The effectiveness of different fiber supplements is difficult to compare given wide differences in water-retention capabilities and effects on the colonic microbial ecology. Given the promising, yet largely unsubstantiated, benefits of fiber supplementation on symptoms of functional constipation, the objective of this clinical trial is to evaluate tolerance and effectiveness of four week supplementation of a fiber product, in a dose-ranging fashion, on whole gut transit time and gastrointestinal symptoms in adults with functional constipation.

What is being measured

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

  1. Whole gut transit time

    To evaluate change in whole gut transit time 2 weeks after consumption of the study product in constipated patients consuming the study product containing fiber in high quantity, compared to those consuming placebo

    Measured: After 2 weeks consumption of the study product

Secondary outcomes (4)
  1. Gastrointestinal symptoms

    To evaluate change in Gastrointestinal symptoms 2\&4 weeks after consumption of the study product in all groups

    Measured: After 2&4 weeks consumption of the study product

  2. Regional colonic transit time

    To evaluate change in the regional (right colon, left colon, and rectosigmoid tranist time 2 weeks after consumption of the study product in all groups

    Measured: After 2 weeks consumption of the study product

  3. Whole gut transit time

    To evaluate change in whole gut transit time 2 weeks after consumption of the study product in constipated patients consuming the study product containing fiber in low quantity, compared to those consuming placebo

    Measured: After 2 weeks consumption of the study product

  4. Tolerance

    To assess tolerance to the study product 1\&2\&4 weeks after consumption in all groups, using a questionnaire

    Measured: After 1&2&4 weeks consumption of the study product

Questions about this trial

What is this clinical trial studying?

A study testing High quantity fiber and Low quantity fiber in people with Constipation, run by Société des Produits Nestlé (SPN) 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 6 inclusion and 15 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 Nov 2015. 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?

Whole gut transit time (time frame: After 2 weeks consumption of the study product). 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 10 Nov 2015.
