About this study
Official title: A Randomized, Placebo-controlled, Double-blind Study to Evaluate the Efficacy of Two Different Mixes of HMO-2FL + Humiome® Post LB Postbiotic (Postbiotic-LB) on Gastrointestinal Symptoms in Irritable Bowel Syndrome (IBS) Subjects
A randomized, placebo-controlled, double-blind clinical study to evaluate the efficacy of two different mixes of HMO-2'-O-fucosyllactose (HMO-2FL) + Humiome® Post LB postbiotic (postbiotic-LB) on Gastrointestinal Symptoms in individuals with Irritable Bowel Syndrome (IBS)
Read the detailed description
This study is a randomized, placebo-controlled, double-blind clinical trial designed to assess the efficacy of two distinct formulations combining Human Milk Oligosaccharide 2'-O-fucosyllactose (HMO-2FL) with Humiome® Post LB postbiotic (postbiotic-LB) in alleviating gastrointestinal symptoms in individuals with Irritable Bowel Syndrome (IBS). Participants will be randomly assigned to receive either of the two active formulations or a placebo, ensuring unbiased comparisons. We aim to evaluate changes in gastrointestinal symptoms, including abdominal pain, bloating, and bowel movement patterns, using validated symptom scoring tools. We will assess the quality of life, gut health biomarkers, and safety profiles. The study employs a double-blind design, where neither participants nor investigators will know the treatment assignments, maintaining the study's integrity. By comparing the effects of different HMO-2FL and postbiotic-LB combinations, this trial aims to provide evidence-based insights into novel dietary supplement options for IBS management, contributing to the growing field of gut health and microbiome-targeted solutions.

What is being measured
The primary outcome is the main question the study is designed to answer.
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose (HMO-2FL) + Humiome® Post LB postbiotic (postbiotic-LB) on IBS symptoms as assessed by IBS Symptom Severity Scale (IBS-SSS), when compared to placebo
The IBS Severity Scoring System (IBS-SSS) will be used to assess symptom severity. Participants will rate their symptoms over the last 10 days on day 0 and day 42. The change in the average IBS severity score will be calculated and compared to the placebo group.
Measured: Day 0 & Day 42
Secondary outcomes (13)
To assess the efficacy of daily consumption of two different mixes of HMO 2'-O-fucosyllactose + Humiome® Post LB postbiotic on IBS symptoms as assessed by IBS Symptom Severity Scale , when compared to placebo in individuals
The IBS Severity Scoring System (IBS-SSS) will be used to assess symptom severity. Participants will rate their symptoms over the last 10 days on day 0 and day 21. The change in the average IBS severity score will be calculated and compared to the placebo group.
Measured: Day 0, Day 21
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose (HMO-2FL) + Humiome® Post LB postbiotic (postbiotic-LB); on IBS symptoms as assessed by IBS-SSS, when compared to baseline in individuals with IBS
The IBS Severity Scoring System (IBS-SSS) will be used to assess symptom severity. Participants will rate their symptoms over the last 10 days on day 0 and day 42. The change in the average IBS severity score will be calculated and compared to baseline in individuals with IBS.
Measured: Day 0, Day 21 and Day 42
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose (HMO-2FL) + Humiome® Post LB postbiotic (postbiotic-LB); on Abdominal Pain severity compared to baseline, each other and placebo in individuals with
Decrease in Abdominal pain severity as assessed by APS-NRS (Abdominal pain severity - Numeric rating scale)
Measured: Day 0, Day 21 and Day 42
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose + Humiome® Post LB postbiotic on participant by Stool consistency (Bristol Stool Form Scale types 3, 4 & 5)
In gastroenterology, stool consistency is commonly measured using the Bristol Stool Form Scale (BSFS), which categorizes stool into seven types, from type 1 (hard lumps) to type 7 (watery diarrhea). It is a simple, cost-effective tool used as a marker for intestinal transit time and bowel function. In this study, stool consistency will be assessed using the BSFS.
Measured: Time Frame: Day 0, Day 21 and Day 42
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose + Humiome® Post LB postbiotic on participant by Quality of Life score as assessed by IBS- QoL questionnaire
The quality of life will be assessed using the IBS-QOL scale. The participants will be asked to score based on their symptoms in the last month at day 0, day 21, and day 42.
Measured: day 0, day 21, and day 42
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose + Humiome® Post LB postbiotic on participant by decreased Abdominal bloating as assessed by Gastrointestinal Quality of Life
The Gastrointestinal Quality of Life Index (GIQLI) is a validated 36-item tool for assessing health-related quality of life across five domains: core symptoms (10 items), physical (6 items), psychological (6 items), social (2 items), and disease-specific (8 items). Each item uses a 0-4 Likert scale, with higher scores indicating better quality of life. Total scores range from 0 to 144, where higher scores reflect improved quality of life.
Measured: day 0, day 21, and day 42
To assess the efficacy on Increased percentage of responders to the treatment based on improvement on primary objective. The IBS-SSS is responsive to treatment; therefore, it has been used as a valid tool for performing responder analysis in IBS studies.
The number of responders will be calculated separately for the two definitions given below in the present study:
- 50 points change in IBS-SSS total score from baseline.
- 95 points change in IBS-SSS total score from baseline.
Measured: day 0, day 21 and day 42

A study testing MIX 1 and MIX 2 in people with IBS (Irritable Bowel Syndrome), run by dsm-firmenich Switzerland AG at 12 sites in India.
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 0 inclusion and 26 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 22 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 12 sites in India. 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.
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?
To assess the efficacy of 6 weeks of daily consumption of two different mixes of HMO 2'-O-fucosyllactose (HMO-2FL) + Humiome® Post LB postbiotic (postbiotic-LB) on IBS symptoms as assessed by IBS Symptom Severity Scale (IBS-SSS), when compared to placebo (time frame: Day 0 & Day 42). 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 22 Jul 2026.
