India384 participantsStarted 2024-07-18
Plain-language summary
The present study is a randomized, double-blind, placebo-controlled, parallel group clinical study that assesses the effect of postbioc on the complaints of subjects with moderate to severe diarrhoea-predominant irritable bowel syndrome (IBS-D). The trial is also evaluating the potential of postbiotic on anxiety, low mood and stress of the participants, as well as its safety and tolerability.
The intervention duration for all the study participants is 12 weeks (intervention phase). Subsequently, the participants will be invited to return to site for an end of study assessment after 21 days of no intervention (post-intervention phase).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Has an IBS-SSS of at least 175 points at screening.
. Individuals either with abdominal pain or discomfort (≥ 6 to ≤ 10 on an 11-point scale).
Exclusion criteria
. Known allergy or hypersensitivity to the components of the investigational product.

. History of diverticulitis, intestinal obstruction, stricture, toxic megacolon, GI (gastro-intestinal) perforation, fecal impaction, gastric banding, bariatric surgery, adhesions, ischemic colitis, or impaired intestinal circulation (e.g., aorto-iliac disease) or recent unexplained GI bleeding within 3 months prior to screening.
