Design outcomes

Primary

MeasureTime frame
Percentage of patients with a 35-point minimum clinically important difference in the IBS symptom severity score (IBS-SSS)Timepoint: week 12 compared to baseline

Secondary

MeasureTime frame
Patients whose total IBS-SSS score decreased by = 50 points at three (4-week) visits. Timepoint: Week 12 compared to baseline;Improvement of abdominal pain by at least 30% on an 11-point NRS for at least 6 weeks out of a 12-week period.Timepoint: week 12 compared to baseline;Change in IBS-QOL score from baseline to week 12.Timepoint: week 12 compared to baseline;Change in IBS-SSS component scores by 30% at week 12.Timepoint: week 12 compared to baseline;Subjective global assessment of relief of IBS symptoms as a dichotomous outcome, with response defined as reporting IBS symptoms are completely, considerably, or somewhat relieved.Timepoint: week 12 compared to baseline;Response rate based on a combination of improvement of abdominal pain by at least 30% and improvement by at least 1 spontaneous bowel movement per week for IBS-C patients.Timepoint: week 12 compared to baseline;Numerical improvement of frequency of bowel movement stratified by IBS type.Timepoint: week 12 compared to baseline;Response rate based on a combination of at least 30% improvement of abdominal pain and at least 50% decrease of days with stool consistency of 6-7 on a Bristol Stool Form Scale for IBS-D patients.Timepoint: week 12 compared to baseline;Response rate based on an increase of one point on a 7-point Likert scale for individual subjective irritable bowel symptoms: abdominal pain, pain during bowel movement, flatulence/bloated stomach, and the urgency to go to the toilet.Timepoint: week 12 compared to baseline;Differences in intake of additional drugs for IBS symptoms.Timepoint: week 12 compared to baseline;Change in the dysbiosis index and intestinal bacterial profileTimepoint: week 12 compared to baseline;Change in levels of serum levels of zonulin from baseline and week 12.Timepoint: week 12 compared to baseline
