About this study

Official title: Pilot Study of Probiotic Bifidobacterium Longum (B. Longum) on Mood and Bowel Symptoms in Patients With Irritable Bowel Syndrome (IBS).

The purpose of this study is to determine whether probiotic bacterium Bifidobacterium longum (B. longum) can improve mood and bowel symptoms in patients with Irritable bowel syndrome (IBS). The patients will be treated with probiotic or placebo for 6 weeks. Their mood, memory, general well-being and bowel symptoms will be assessed before, at the end of the treatment and 4 weeks later. Brain activation pattern, changes in gut bacteria, metabolic profile and inflammatory markers will be also measured.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Bifidobacterium longum and Maltodextrin in people with Irritable Bowel Syndrome and IBS, run by Société des Produits Nestlé (SPN) 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 11 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 5 Aug 2014. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Hospital Anxiety and Depression (HAD) scale. (time frame: 6 weeks post-treatment initiation). 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 NCT01276626, 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 5 Aug 2014.
