About this study

Official title: Effects of 4-week Bifidobacterium-lactis HN019 Supplementation on Colonic Transit Time and Gastrointestinal Symptoms in Adults With Functional Constipation: A Double-blind, Randomized, Placebo-controlled Dose-ranging Trial

To determine if Bifidobacterium lactis HN109 improves transit time and gastrointestinal symptoms in adults with constipation.

Read the detailed description

Constipation is a commonly diagnosed gastrointestinal disorder with an estimated prevalence in the general population of 12-19%, which results in lower quality of life and significant healthcare costs to the individual. Almost 9 in 10 physician visits for constipation result in a laxative prescription. Additionally, consumers in the USA and in the United Kingdom spend almost 1 billion dollars annually for over-the-counter laxatives. Chronic constipation is diagnosed almost solely on patient symptoms, which generally includes unsatisfactory defecation due to infrequent stools, difficult stool passage, or both. The cause of chronic constipation is unknown and likely multifactorial with physiological changes, psychological factors, and lifestyle influences identified as possible culprits. Consequently, identification of effective constipation treatments remains a challenge.

The initial management of constipation symptoms is focused on evaluating lifestyle and diet variables as possible culprits. If lifestyle modifications are unsuccessful in alleviating constipation, various medications may be prescribed. In fact, about 50% of adults with constipation are not completely satisfied with available treatments. Consequently, there is a clear need for alternative constipation treatments that are safe, effective, and cost-effective.

Probiotics are live micro-organisms that result in a health benefit for the host when administered in adequate dosages. In recent years, probiotics have been commonly used to alleviate symptoms in a variety of gastrointestinal disorders. It is hypothesized that probiotics help to maintain gut lumen homeostasis by hindering growth of luminal pathogens and restoring the normal flora of the gut. As such, the use of probiotics for the relief of constipation symptoms is very promising. Numerous studies have been published addressing the utility of probiotics for gastrointestinal health including constipation. However, since probiotic efficacy is largely strain-specific, each specific strain must be individually tested in clinical trials.

Given the promising clinical results of probiotics on gastrointestinal health to date, the objective of this clinical trial is to evaluate the safety and effectiveness of 4-week Bifidobacterium lactis HN019 supplementation, in a dose-ranging fashion, on Colonic Transit Time (CTT) and gastrointestinal symptoms in adults with constipation.

What participants receive

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

  • Probiotic Bifidobacterium 1x1010 cfuDietary supplement

    Also called Probiotic powder (1 x1010 cfu B. lactis HN019) in capsules

    Participants who pass the initial screening will enter a 2-week placebo-only run-in period. Participants who successfully complete the run-in period will be randomized to daily supplementation with B. lactis HN019 (1 x 1010 cfu), B. lactis HN019 (1 x 109 cfu), or placebo for 4 weeks.

  • Probiotic Bifidobacterium 1x109 cfuDietary supplement

    Also called Probiotic powder (1 x 109 cfu B. lactis HN019) in capsules

    Participants who pass the initial screening will enter a 2-week placebo-only run-in period. Participants who successfully complete the run-in period will be randomized to daily supplementation with B. lactis HN019 (1 x 1010 cfu), B. lactis HN019 (1 x 109 cfu), or placebo for 4 weeks. One capsule of study product, mixed with provided yogurt, will be consumed once a day.

  • Placebo powder in capsulesOther

    Participants will consume placebo capsules only during the 2-week run-in period. After randomization, participants will be administered their assigned study product and will continue on the product for 4 weeks.

What is being measured

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

  1. Colonic transit time

    Measured: The primary outcome of Colonic Transit Time will be evaluated with abdominal x-rays on days 0 and 28

Secondary outcomes (10)
  1. Patient (syn. participant) assessment of constipation symptoms (PAC-SYM)

    Measured: At days 0 and 28

  2. Patient Assessment of Constipation Quality of Life (PAC-QoL)

    Measured: At days 0 and 28

  3. Bowel Function Index

    Measured: At days 0 and 28

  4. Adequate Relief of constipation (yes/no)

    Measured: At days 0 and 28

  5. Bowel movement frequency stools per week)

    Measured: Participants will record the number of defecations per day in a daily diary during the 2-week run-in period and each day during the 4-week supplementation period

  6. Stool consistency (Bristol Stool Scale)

    Measured: Participants will record stool consistency during the 2-week run-in period and each day during the 4-week supplementation period.

  7. Degree of Straining (1-5 scale)

    Measured: Participants will record degree of straining during the 2-week run-in period and each day during the 4-week supplementation period.

  8. Participant assessment of bowel emptying (yes/no)

    Measured: Participants will record sensation of complete bowel emptying during the 2-week run-in period and each day during the 4-week supplementation period.

  9. Abdominal discomfort/bloating (1-5 scale)

    Measured: Participants will record severity of abdominal discomfort and bloating during the 2-week run-in period and each day during the 4-week supplementation period.

  10. Overall product satisfaction (1-5 scale)

    Measured: At the end of the supplementation period (D28)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Probiotic Bifidobacterium 1x1010 cfu and Probiotic Bifidobacterium 1x109 cfu in people with Constipation and Gastrointestinal Disorder, run by Danisco Sweeteners Oy at 1 site in France.

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 11 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 7 May 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 France. 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 phase mean?

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?

Colonic transit time (time frame: The primary outcome of Colonic Transit Time will be evaluated with abdominal x-rays on days 0 and 28). 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 7 May 2015.
