About this study
Official title: Effect of Lactibiane Tolerance®, a Multistrain Probiotic, to Treat Leaky Gut in Irritable Bowel Syndrome With Predominant Diarrhea (IBS-D) Patients: an Open-label, Single-center, Proof-of-concept, Pilot Study
This is a Phase IV, open-label, single-center, proof-of-concept, pilot study to evaluate the effect of Lactibiane Tolerance® in treating leaky gut in IBS-D patients.
30 consecutive patients with IBS-D and an increased intestinal permeability assessed by 51Cr-EDTA or 99mTc-DTPA will receive the multistrain probiotic Lactibiane Tolerance® 10 billion CFU 1 capsule twice a day (30 minutes before breakfast and 30 minutes before dinner) for 30 days treatment. At the end of treatment, patients will repeat intestinal permeability assessment by 51Cr-EDTA or 99mTc-DTPA.
Read the detailed description
Gut microbiota has many beneficial effects on the GI tract: barrier, immunomodulatory, metabolic, trophic among others. Microbiota unbalance or dysbiosis has been associated to digestive and extradigestive diseases.
Irritable bowel syndrome (IBS) is a common chronic disorder that affects the small and large intestine which causes cramping, abdominal pain, bloating, gas, diarrhea and/or constipation. Only a small number of people with IBS have severe signs and symptoms. Some people can control their symptoms by managing diet, lifestyle and stress. Others will need medication and counseling.
Intestinal permeability is the phenomenon of the gut wall in the gastrointestinal tract exhibiting permeability. It is a normal function of the intestine to exhibit some permeability, to allow nutrients to pass through the gut, while also maintaining a barrier function to keep potentially harmful substances (such as antigens) from leaving the intestine and migrating to the body more widely. In a healthy human intestine, small particles (< 4 Å in radius) can migrate through tight junction claudin pore pathways and particles up to 10-15 Å (3.5 kDa) can transit through the paracellular space uptake route. One way in which intestinal permeability is modulated is via CXCR3 receptors in the gut wall, which respond to zonulin. Gliadin (a glycoprotein present in wheat) activates zonulin signaling irrespective of the genetic expression of autoimmunity, leading to increased intestinal permeability to macromolecules. Bacterial pathogens such as cholera, select enteric viruses, and parasites modulate intestinal tight junction structure and function, and these effects may contribute to the development of chronic intestinal disorders. Excessive intestinal permeability is a factor in stress, infections and in some several autoimmune conditions such as Crohn's disease, celiac disease, type 1 diabetes, rheumatoid arthritis, spondyloarthropathies, inflammatory bowel disease and irritable bowel syndrome, but it is not clear if increased intestinal permeability is a cause or a consequence of these conditions.
According to its ability to modulate gut associated immune system, to compete with other GI bacteria and to increase enterocyte regeneration, probiotic therapy could be proposed to overcome an increased intestinal permeability. In particular, preliminary data suggested that the probiotic multistrains Lactibiane Tolerance® could be effective in Leaky gut treatment.
In fact, Nébot-Vivinus et al. demonstrated that Lactibiane Tolerance® could prevent epithelial barrier disruption induced by lipopolysaccharide, stress or colonic soluble factors from IBS patients and prevent visceral hypersensitivity in experimental models of epithelial barrier function.
Furthermore, Drouault-Holowacz et al. demonstrated that Lactibiane Tolerance® has anti-inflammatory properties in vitro by stimulating IL-10 production and in vivo by conferring a significant protective effect in the 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis -induced colitis model (more than 50% decrease of colitis symptoms, P<0.01).This pilot study has been designed to evaluate the effect of multistrains probiotic Lactibiane Tolerance® in a consecutive subset of IBS-D patients with increased Intestinal permeability.
Subject participation in this study will be for approximately 45 days which includes up to a 2-week screening period and a 30-day treatment period.
All subjects will participate to the following visits: screening, enrolment, day 15 and day 30.

Questions about this trial
What is this clinical trial studying?
A study testing Multistrain probiotic in people with IBS - Irritable Bowel Syndrome, run by Larena SAS at 1 site in Italy.
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 11 inclusion and 9 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 24 May 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 Italy. 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. 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?
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?
Proportion of subjects with normal intestinal permeability assessed by 51Cr-EDTA or 99mTc-DTPA (time frame: 30 days). 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 24 May 2021; AzTrials last refreshed its copy on 8 Nov 2026.
