12 weeks
Incidence of adverse (and serious) events
12 weeks

Eligibility Criteria
You may qualify if:
- Age 18-75 years
- Recurrent abdominal pain, at least one day/week in the last 3 months (with symptom onset at least 6 months before diagnosis), associated with two or more of the following criteria (Rome IV criteria)
- Related to defecation
- Associated with a change in frequency of stool
- Associated with a change in form (appearance) of stool.
- Moderate to severe abdominal pain as defined with an IBS Symptoms Severity Scale (IBS-SSS) score \> 175
- Patient reports that abnormal bowel movements are usually diarrhea with more than one-fourth (25%) of bowel movements with Bristol stool form types 6 or 7 and less than one-fourth (25%) of bowel movements with Bristol stool form types 1 or 2. Starting during the screening/run-in phase, all patients will keep diaries of stool frequency and consistency. Stool consistency will be assessed according to the Bristol Stool Form scale (Lewis and Heaton, 1997)
- Stable eating habits, within one month before randomization
- In patients \> 50 years colonoscopy performed during the past 5 years demonstrates no pathology associated with the symptoms reported for IBS
- Ability to understand trial instructions and to comply with treatment
- Patient agree to be compliant for study interactive web - response system schedule confirmed at time of randomization
- Written informed consent prior to enrolment
You may not qualify if:
- Patient has exclusively constipation-predominant IBS (IBS-C) that is characterized by \< 3 bowel movements/week or hard and lumpy stools (e.g. Bristol stool form types 1 or 2)
- Patient has irritable bowel syndrome with mixed bowel habits (IBS-M) with varying symptoms of constipation and diarrhea
- Calprotectin stool value \> 200mg/kg stool
- Known hypersensitivity to the IMD (known aluminium and/or silicon hypersensitivity)
- Patient has failed to record \>50% of daily diary entries during run-in period
- Rectal bleeding in the absence of documented bleeding hemorrhoids or anal fissures assessed by fecal occult blood test
- History of major gastric, hepatic, pancreatic or intestinal surgery or perforation with exception of appendectomy, cholecystectomy and inguinal hernia
- Patients with a history of positive tests for ova, parasites or clostridium difficile must undergo repeat testing, which must be negative, during the screening period
- Use of the following prohibited medications: any antibiotics including rifaximin within the past 2 months or during treatment period, use of cholestyramine during entire study period, during run-in phase and during the treatment period any use of concomitant medication effecting the gastrointestinal movement and/or function (e.g. anticholinergic drugs, 5-HT3 receptor antagonists, prokinetic agents, intestinal flora regulating drugs, parasympathetic inhibitors, opioids or eluxadoline)
- Use of immunosuppressive drugs within the last 6 months or planned use of immunosuppressive drugs during the study
- Patients treated with tricyclic antidepressants
- Serotonin re-uptake inhibitors are allowed if the patient is at stable dose for at least 8 weeks prior to signing informed consent and the dose will remain stable throughout the duration of the study.
- History of inflammatory or immune-mediated gastrointestinal (GI) disorders including inflammatory bowel disease (i.e., Crohn's disease, ulcerative colitis) and celiac disease (by anamnesis and assessed by tTGA levels)
- Active infection, or abnormalities in laboratory testing, vital signs, or physical examination at screening
- Participation in any other interventional clinical trial within 4 weeks before study participation
- +9 more criteria
