Trial summary

The microbiota is associated with a wide spectrum of diseases including diabetes and non-alcoholic fatty liver disease. In this study we will investigate if the bacteria F. prausnitzii, which is a part of the human gut microbiota, can improve metabolic parameters in subjects with impaired glucose control.

About this study

Official title: Effect of F. Prausnitzii on Glycemic Control - a Randomized, Double Blind, Placebo-controlled Study

The microbiota is associated with a wide spectrum of diseases including diabetes and non-alcoholic fatty liver disease. In this study we will investigate if the bacteria F. prausnitzii, which is a part of the human gut microbiota, can improve metabolic parameters in subjects with impaired glucose control.

Read the detailed description

This is a randomized, double blind, placebo-controlled study. Subjects with impaired glucose control will after signing the informed consent and fulfilling the study criteria be randomized to study product or placebo. The randomization ratio between the study product (F. prausnitzii 1E8-5x1E8 CFU and D. piger) and placebo is 1:1. In total 176 subjects will be randomized in the study.

The study will start with a Run-in period i.e. all the subjects will be given placebo capsules. The subjects fulfilling the inclusion and exclusion criteria will be randomized at Visit 2 to either study product or placebo in the ration 1:1. The treatment will last for 12 weeks, from Visit 2 to Visit 6. The study is ended with a 2-week period of follow up after the final dose.

Blood samples are taken at Visits 1-4 and Visits 6-7. Feces samples are collected at Visit 2-7. One additional fecal sample will be sent by mail approximately one week after Visit 1. Glucose monitoring (CGM) will be initiated at Visit 1 and Visit 5 and followed for 10 days.

Questions about this trial

What is this clinical trial studying?

A study testing F. prausnitzii and D. piger in people with Pre Diabetes and Impaired Glucose Tolerance, run by MetaboGen AB at 1 site in Sweden.

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 22 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: status not confirmed, as of the sponsor's last update on 2 Sep 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 Sweden. 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?

Results are not available in the source record.

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

Contact Sara Maclus, PhD (+46 705823222, sara.malcus@metabogen.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Glycemic control (time frame: From baseline to week 12). 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 2 Sep 2021.
