What is being measured

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

  1. Change from baseline in inflammatory markers

    Change in inflammatory markers in the serum and secreted cytokines from lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells compared to baseline. In the serum the markers to be investigated are high sensitivity c-reactive protein (hs-CRP), tumor necrosis factor alpha (TNF-a), interleukin 1 beta (IL-1B), IL-6, IL-8, IL-10, IL-12p70, monocyte chemotactic protein 1 (MCP-1), macrophage inflammatory protein alpha (MIP-1a), sCD14, and LPS binding protein (LPB). From LPS-stimulated peripheral blood mononuclear cells the cytokines to be investigated are TNF-a, IL-1B, IL-6, IL-8, IL-10, IL-12p70, MCP-1, and MIP-1a. Changes in these inflammatory markers will assist in understanding how the consumption of yogurt containing BB-12 affects the inflammatory status of obese individuals.

    Measured: At baseline before intervention period 1, at endpoint of intervention period 1 (week 4), at baseline before intervention period 2 (week 8), at endpoint after intervention period 2 (week 12)

Secondary outcomes (4)
  1. Change in number and activation of leukocytes

    Change in quantity and activation of T cells, B cells, dendritic cells, natural killer cells, and monocytes measured by flow cytometry before and after each period. Changes in the number and activation of leukocytes will assist in understanding the impacts of the consumption of yogurt containing BB-12 on leukocytes in obese individuals.

    Measured: At baseline before intervention period 1, at endpoint of intervention period 1 (week 4), at baseline before intervention period 2 (week 8), at endpoint after intervention period 2 (week 12)

  2. Change in gut permeability

    Change in gut permeability, assessed using a lactulose/mannitol gut permeability assay, from baseline. Changes in gut permeability will assist in understanding the impacts of the consumption of yogurt containing BB-12 on gut health and permeability in obese individuals.

    Measured: At baseline before intervention period 1, at endpoint of intervention period 1 (week 4), at baseline before intervention period 2 (week 8), at endpoint after intervention period 2 (week 12)

  3. Change in gut microbiota populations

    Change in gut microbiota populations, assessed with 16s ribosomal ribonucleic acid (rRNA), compared to baseline. Changes in microbial populations will assist in understanding the impacts of the consumption of yogurt containing BB-12 on commensal gut microbiota in obese individuals.

    Measured: At baseline before intervention period 1, at endpoint of intervention period 1 (week 4), at baseline before intervention period 2 (week 8), at endpoint after intervention period 2 (week 12)

  4. Change in metabolism of gut microbiota populations

    Change in the metabolism of gut microbiota populations, measured via transcriptomics, compared to baseline. Changes in the transcriptome of the commensal microbiota will assist in understanding the impacts of the consumption of yogurt containing BB-12 on the metabolism of commensal gut microbiota in obese individuals.

    Measured: At baseline before intervention period 1, at endpoint of intervention period 1 (week 4), at baseline before intervention period 2 (week 8), at endpoint after intervention period 2 (week 12)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Yogurt smoothie with BB-12 and Yogurt smoothie in people with Metabolic Syndrome, run by Penn State University 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 7 inclusion and 13 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: looking for participants now, as of the sponsor's last update on 14 Dec 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 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.

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Connie J Rogers, PhD, MPH (814 867 3716, cjr102@psu.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in inflammatory markers (time frame: At baseline before intervention period 1, at endpoint of intervention period 1 (week 4), at baseline before intervention period 2 (week 8), at endpoint after intervention period 2 (week 12)). 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 NCT03418857, which also lists 6 linked publications.

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 Dec 2021.
