About this study

Official title: Effects of a Probiotic Supplement on Gastrointestinal Symptoms and Microbiome Modulation

This randomized, placebo-controlled, double-blind study will determine the effect of daily supplementation with a probiotic blend in 60 apparently healthy men and women recruited at a single investigational center in Northeast Ohio (i.e., The Center for Applied Health Sciences).

Subjects will attend three study visits. During Visit 1, subjects will be screened for participation [i.e., medical history, routine blood work, background baseline diet]. During Visits 2 and 3 subjects will complete questionnaires that assess their gastrointestinal health (e.g., abdominal discomfort/bloating, constipation, regularity, stool consistency). Visits 2 and 3 will correspond to before (week 0) and after six weeks of supplementation, respectively, with the probiotic dietary supplement or placebo.

Being tested
575mg [30 billion colony forming units] probiotic blend of Bifidobacterium breve, Lactobacillus acidophilus, Lacticaseibacillus rhamnosus, Saccharomyces boulardii, and alpha amylase
Medical subject headings

What is being measured

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

  1. Flatulence (gas)

    Flatulence (gas) as measured by a 10 cm visual analogue scale, where higher values represent greater flatulence.

    Measured: Change from baseline to 6 weeks.

  2. Gastro-intestinal bloating

    Gastro-intestinal bloating as measured by a 10 cm visual analogue scale, where higher values represent greater bloating.

    Measured: Change from baseline to 6 weeks.

  3. Abdominal discomfort

    Abdominal discomfort as measured by a 10 cm visual analogue scale, where higher values represent greater discomfort.

    Measured: Change from baseline to 6 weeks.

  4. Gastrointestinal Symptom Rating Scale (GSRS)

    Gastrointestinal problems as measured by the GSRS questionnaire, where higher values represent increased severity of gastrointestinal problems.

    Measured: Change from baseline to 6 weeks.

Secondary outcomes (3)
  1. Stool consistency

    Stool consistency as measured by a 10 cm visual analogue scale, where higher values represent harder stools.

    Measured: Change from baseline to 6 weeks.

  2. Stool regularity

    Stool regularity as measured by a 10 cm visual analogue scale, where higher values represent more regular stools.

    Measured: Change from baseline to 6 weeks.

  3. Constipation

    Constipation as measured by a 10 cm visual analogue scale, where higher values represent more greater constipation.

    Measured: Change from baseline to 6 weeks.

Questions about this trial

What is this clinical trial studying?

A study testing 575mg [30 billion colony forming units] probiotic blend of Bifidobacterium breve, Lactobacillus acidophilus, Lacticaseibacillus rhamnosus, Saccharomyces boulardii, and alpha amylase in people with Microbiota and Constipation, run by The Center for Applied Health Sciences, LLC at 1 site in United States.

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 14 Nov 2022. 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 United States. 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?

Flatulence (gas) (time frame: Change from baseline to 6 weeks.). The study lists 4 primary outcomes in all. 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 NCT05614726, 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 14 Nov 2022.
