About this study

Official title: Interventional, Randomized, Single-blind, Placebo-controlled Study to Evaluate the Effect of a Probiotic Formulation Based on SF68® on Body Composition and Low-to-moderate Cardiovascular Risk

Obesity is a multifactorial disorder of energy balance, characterized by an imbalance between energy intake and energy consumption. In recent decades, the prevalence of obesity has reached epidemic proportions. Advances in scientific research have enabled better characterization of the etiology of obesity, highlighting the potential contribution of factors not traditionally considered to be involved in changes in energy balance and body composition, such as the gut microbiota. Oral administration of probiotics has been proposed as a valid way to modulate the gut ecosystem to promote weight reduction. Preliminary data from a preclinical study in mouse models suggest that the dietary supplement SF68® containing the probiotic Enterococcus lactis as well as phytosterols and (6S)-5-methyltetrahydrofolic acid has the ability to significantly counteract weight gain. In addition to modulating the composition of the gut microbiota, it also has an impact on decreasing the levels of total cholesterol, low-density cholesterol (LDL), triglycerides, homocysteine, IL-1 β and LPS Binding Protein (LBP). Although exercise and diet are the first lines of intervention to be recommended, there are often failures or poor results. There is currently increased interest in alternative and effective shorter-term, non-pharmacological approaches to weight control that involve the use of natural active ingredients. Thus, the aim of this intervention study is to investigate whether a supplementation with SF68® could be beneficial for the weight reduction and the improvement of cardiovascular risk profile of people with overweight or obesity.

What participants receive

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

  • ProbioticDietary supplement

    The experimental product is a dietary supplement manufactured by Cerbios-Pharma S.A, Each stick contains probiotic live cultures of Enterococcus lactis SF68® at a concentration of 10^9 CFU, phytosterols, 6S-5MeTHF, maltose and silicon dioxide. Study participants will be given N°3 packs each containing 30 stick packs of 1.7 g each, in granulated form in sufficient quantity for the entire duration of the study (12 weeks). Subjects will be required to consume N°1 stick pack of the supplement daily after dinner for 12 continuous weeks. The product should be placed directly on the tongue and should be taken without water. After taking the product, the subject should drink half a glass of water to promote solubilization and transit. The supplement should be stored in a cool, dry place, away from light, moisture and direct heat sources to ensure the viability of the probiotic strain until the expiration date.

  • PlaceboDietary supplement

    N°1 stick/day of placebo food supplement (i.e., stick without added probiotics), with the same intake modalities as probiotic.

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?

Waist circumference (time frame: 12 weeks). 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 NCT06795607, 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 28 Jan 2025.
