About this study

Official title: The Effect of a Multi-strain Live Bacteria Supplement on the Gut Microbiota Composition of Healthy Adults: an Open Label Trial

Over recent years there has been a lot of research looking at how the bacteria in our gut affect our health. Changes to gut bacteria has been linked to several diseases. Taking specific live bacteria supplements (sometimes known as 'probiotics'), to change the balance of our gut bacteria to result in a health benefit have been trialled as a treatment option for many diseases in recent years.

Bio-Kult Advanced is a live bacteria Food supplement that contains 14 different bacteria cultures. The effect of Bio-Kult Advanced on gut bacteria is unknown, therefore, the aim

Read the detailed description

There is rapidly growing interest in the involvement of the microbiome in health. Imbalance in human gut microbiota, 'dysbiosis', has been linked to several diseases. Manipulation of the microbiome, using specific strains of live micro-organisms, that confer a health benefit on the host (probiotics), have therefore become an exploratory treatment option in microbiome-associated diseases in recent years. Numerous studies have shown selected strains of bacteria to show statistically significant and clinically relevant improvement in symptoms, in a number of diseases, including but not limited to infantile colic and atopic dermatitis.

Bio-Kult Advanced (BKA) is a 14 strain live bacteria supplement containing a Minimum 2 billion live microorganisms per capsule (2x109 CFU/capsule), equivalent to 10 billion live microorganisms per gram (1x1010 CFU/gram). A randomised controlled trial of Bio-Kult Advanced in the management of diarrhoea predominant IBS demonstrated significant improvement in gastrointestinal (GI) symptoms and was well tolerated by participants. Another randomised controlled trial of Bio-Kult Advanced, in participants with episodic and chronic migraine sufferers, demonstrated significant improvement in frequency and severity of migraines compared to placebo. This clinical effectiveness across various conditions, suggest that bacterial strains in Bio-Kult could have an effect on the gastrointestinal flora, however data has yet to be collected that explores the effect of Bio-Kult on the microbiome. The aim of this study is to therefore investigate the effect of Bio-Kult Advanced, on the composition of the gut microbiota in healthy adults.

What participants receive

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

  • Fasted breath samplesOther

    Participants will provide fasted breath samples pre and post Bio-Kult Advanced.

  • Daily DiaryOther

    Monitoring stool form, consistency and frequency on a daily basis.

  • Stool sampleOther

    Participants will provide stool sample pre and post Bio-kult Advanced.

What is being measured

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

  1. Stool sample comparison

    Comparison between samples at different taxonomical levels (phylum, family, genus and species) will be performed for the identification of specific bacteria in samples of interest. Accumulative bar charts will be provided for rapid inspection. PCA and clustering will be conducted. Biodiversity Index (Shannon, Simpson, Gini-Simpson or Berger-Parker) will be calculated. Biostatistics will be done in order to detect biomarkers between timepoints of the study.

    Measured: 56 days

Secondary outcomes (2)
  1. Fasting breath samples

    Mean change in fasted breath hydrogen and methane, will be determined from baseline to end of study. Mean fasted hydrogen and mean fasted methane will be calculated independently of one each other. Breath hydrogen and breath methane will be measured in units of parts per million (ppm). Statistical significance will be determined using a paired t-test (p<0.05).

    Measured: 56 days

  2. Bowel habit

    Mean difference in stool frequency and consistency from baseline and end of study will be determined using a paired t-test, to determine significance (p<0.05).

    Measured: 56 days

Questions about this trial

What is this clinical trial studying?

A study testing Fasted breath samples, Daily Diary and Stool sample in people with Microbial Colonization, run by The Functional Gut Clinic at 1 site in United Kingdom.

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 21 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 16 Feb 2021. 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 Kingdom. 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. 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?

Stool sample comparison (time frame: 56 days). 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 16 Feb 2021.
