About this study

Official title: The Effect of Separate or Combined Supplementation of Probiotic (Bifidobacterium Lactis B420) and Polydextrose on Body Fat Mass

Obesity is a major problem worldwide, and it is related to abnormalities in glucose and lipid metabolism. The purpose of this study is to investigate the effect of a dietary supplement containing probiotic (Bifidobacterium animalis ssp. lactis 420) and/or prebiotic (Litesse) on change in body fat mass in a double-blind, randomized, placebo-controlled intervention trial. The supplement is ingested once per day for the duration of six months, and participants will attend a follow-up visit one month after the end of the intervention. The study will enroll 232 participants (58 per study arm) in four research centers in southern Finland.

Read the detailed description

Obesity is a major problem worldwide, and it is related to abnormalities in glucose and lipid metabolism. Preclinical studies have shown that weight gain and insulin resistance may be prevented by oral administration of the probiotic Bifidobacterium animalis ssp. lactis 420. Furthermore, the prebiotic polydextrose has shown efficacy on satiety in clinical settings. The purpose of this study is to investigate the effects of these products, individually and combined, on change in body fat mass in a double-blind, randomized, placebo-controlled intervention trial. The study is conducted at four research clinics in southern Finland. The supplement is provided in a sachet, mixed into a fruit smoothie and ingested once per day for the duration of six months. One month from the end of the intervention participants will attend a follow-up visit. The study will enroll 232 participants, who will be randomized into blocks using a computerized procedure.

After the screening visit, there will be seven study visits (once per month) and one follow-up visit. Visits at months 0, 2, 4, 6 and follow-up are clinic visits, and visits at months 1, 3 and 5 are phone contacts to check compliance and any adverse events.

Clinic visits include the following measurements and samples:

  • weight
  • blood pressure and heart rate
  • blood samples
  • returning of food diaries (only during intervention)
  • returning of exercise questionnaires and food choice questionnaires (only beginning and end of treatment)
  • returning of fecal samples, taken at home by participant
  • DXA for body composition analysis
  • hip and waist circumference
  • brief physical examination (only beginning and end of treatment)
  • recording of adverse events and concomitant medication

For compliance check, unused sachets are returned to the clinic and counted. At the follow-up visit participants will receive guidance on exercise and a healthy diet.

The primary variable of this study is relative change from baseline to end-of-treatment in body fat mass. Comparisons between each of the active groups against the placebo group will be performed if the global P-value is significant. Secondary variables will be analyzed in a similar fashion. The relative and absolute changes in body fat mass will also be analyzed. To explore the mechanism of potential treatment benefits, post-hoc responder analyses may optionally be performed. Also, correlations between the response variables may be examined in exploratory analyses. Post-hoc analyses may be conducted to compare e.g. different time points or to analyze differences from end-of-treatment to follow-up.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bifidobacterium animalis ssp. lactis 420 and Polydextrose in people with Obesity and Hyperglycemia, run by Danisco at 4 sites in Finland.

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 23 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 2 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Finland. 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?

Difference in body fat mass from baseline to end-of-treatment (6 months) (time frame: From baseline to end of intervention (6 months)). 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 NCT01978691, which also lists 3 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 2 Feb 2016.
