Brief Summary

Irritable bowel syndrome (IBS) is a highly prevalent functional pathology which currently has no real standardized and effective therapy, despite having a significant impact on quality of life and on social-health costs.

Post-biotics have demonstrated in various in vitro and in vivo studies the ability to modulate the microbiota, the intestinal barrier function, the immune response as well as having systemic effects, with prospects for good efficacy in treatment of IBS.

Detailed Description

PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220, mallow and chamomile.

The Fermented FOS from Lactobacillus paracasei CNCM I-5220 (postbiotic) is the result of a controlled fermentation. The fermentation process allows to eliminate all the individual variability that depends on the microbiota, the diet and the psycho-physical conditions of the single individual, offering a mixture of bacterial metabolites and fermented fiber (postbiotic), which has the functional activity. In addition, as FOS is already fermented it does not induce the formation of gas typical of fiber fermentation in IBS patients, thus providing all the beneficial effects of the fiber without its side effects.

The fermented FOS from Lactobacillus paracasei CNCM I-5220 (postbiotic) is easily absorbed by the gut.

Dosage and method of use: PostbiotiX Slowing 4 g sachets, administered at the dosage of one sachet a day. To pour the contents of the sachet in a glass, add 150 ml of water, mix until complete dissolution of the powder and taken immediately, preferably as soon as awakened, and away from meals.

Ingredients: Maltodextrin, Aroma, Fermented FOS from Lactobacillus paracasei CNCM I-5220, mallow (Malva sylvestris L.) flowers and leaves d.e. tit. 20% polysaccharides, chamomile (Matricaria chamomilla L.) flowers d.e. tit. 0.3% apigenin, acidity regulator: citric acid; anti-caking agent: silicon dioxide; sweetener: sucralose.

Conservation method: to be kept in a cool and dry place, away from light, humidity, and direct sources of heat.

Placebo (Tratment B) Sequence BAPostbiotiX Slowing 4 g sachets PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220.Each patient will be supplied with the investigational product at Visit 0 (V0, Kit V0, Placebo) and at visit 3 (V3, Kit V3, PostibiotiX Slowing), based on the outcome of the randomization at V0 (Sequence BA, Placebo/PostbiotiX Slowing).
PostbiotiX Slowing (Treatment A) Sequence ABPostbiotiX Slowing 4 g sachets PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220.Each patient will be supplied with the investigational product at Visit 0 (V0, Kit V0, PostibiotiX Slowing) and at visit 3 (V3, Kit V3, Placebo), based on the outcome of the randomization at V0 (Sequence AB, PostbiotiX Slowing/Placebo).
Primary Outcome Measures
NameTimeMethod
Reduction in symptom intensity10 weeks

Evaluated using a symptom measurement scale, at each visit, on a 4-point Likert scale (IBS symptom scale; 4 symptoms for a minimum sum score of 0, maximum 12).

Secondary Outcome Measures
NameTimeMethod
Change from baseline after treatment in QqL:up to 10 days

Quality of life as assessed by IBS-QoL:

The individual responses to the 34 items are summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of life

Fecal metagenomics:up to 10 days

Additional functional parameters in stool analysis differences before and after treatment (for example: digestive residues, bile acids, proteic composition)

Change from baseline in IBS-SSS (symptom severity score)up to 4 weeks

IBS-SSS is a five-item questionnaire measuring frequency and intensity of abdominal pain, the severity of abdominal distension, dissatisfaction with bowel habits, and the interference of IBS with daily life, scoring from 0 to 500.

Change from baseline after treatment in NRS:up to 10 days

Severity score of each of the individual symptoms included in the IBS-SSS (VAS sub-scores), assessed by numeric rating scale (NRS) from 0 to 100

Change from baseline after treatment in HADS:up to 10 days

Hospital anxiety and depression scale (HADS):

HADS is a fourteen-item scale with seven items each for anxiety and depression subscales. Scoring for each item ranges from zero to three. A subscale score \>8 denotes anxiety or depression.

Analyses of metabolomic:up to 10 days

Differences before and after treatment in the Sieric/plasma molecules such as for example Zonulin, soluble CD14, plasmatic inflammatory cytokines, bacterial DNA in the blood, and PBMCs analysis

Adequate overall symptom relief after treatment,up to 10 days

To assess adequate overall relief, patients will be asked weekly to answer the question "Compared to how you usually felt before taking the treatment, how would you rate your symptom relief (abdominal pain, bowel habits, and other symptoms of IBS) in the past 10 days?" Possible answers: 1, very relieved; 2, relieved; 3, somewhat relieved; 4, unchanged; 5, slightly worsened; 6, worsened; 7, much worsened.
