Investigation of the Efficacy of a Probiotic Mixture in Moderate Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD): A Mechanistic Trial

NCT ID: NCT07193927

Last Updated: 2026-01-22

Basic Information

• Recruitment Status: NOT_YET_RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 60 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2026-01-31
• Study Completion Date: 2027-06-01

Brief Summary

The goal of this clinical trial is to evaluate whether a specific probiotic mixture can improve liver health in adults with moderate metabolic dysfunction-associated steatotic liver disease (MASLD).

The main questions it aims to answer are:

Can the probiotics improve liver fat and stiffness as measured by non-invasive imaging (FibroScan® CAP and FAST scores)? Does the probiotic affect other health markers like cholesterol, blood sugar, inflammation, and gut bacteria?

Researchers will compare people taking the probiotic to those taking a placebo (a capsule with no active ingredients) to see if the probiotic has beneficial effects.

Participants will:

Be randomly assigned to take either the probiotic or placebo daily for 6 months.

Attend 3 study visits (at the start, 3 months, and 6 months). Provide blood and stool samples. Undergo liver scans (FibroScan®). Complete a health and nutrition questionnaire.

This study includes adults aged 18-65 with moderate MASLD and certain metabolic health conditions. Participants must not be pregnant, breastfeeding, or taking certain medications or supplements that could interfere with the study.

Conditions

Study Groups

Probiotic

Group Type: ACTIVE_COMPARATOR

Lactiplantibacillus plantarum Probiotic Mixture

Intervention Type: DIETARY_SUPPLEMENT

A daily oral probiotic capsule containing three specific strains of Lactiplantibacillus plantarum (KABP011, KABP012, KABP013) 1,2 billion CFU with vitamin B1, designed to modulate gut microbiota and improve liver health in MASLD patients. It is compared to a placebo in a 6-month, double-blind, mechanistic trial.

Placebo

Group Type: PLACEBO_COMPARATOR

Placebo comparator containing maltodextrin

Intervention Type: DIETARY_SUPPLEMENT

Placebo comparator containing maltodextrin
