- Have a self-reported average abdominal bloating rating (>3 daily ratings over the preceding 7 days) equal or greater than 4 on a numerical scale of 0 to 20.

Exclusion Criteria:

- Have a structural or metabolic disease or condition that affects the GI system, excluding asymptomatic gallstones or uncomplicated gastroesophageal reflux disease, or any medical condition that may be a cause of constipation or diarrhea (e.g., hypothyroid status, poorly controlled diabetes, diabetic neuropathy or autonomic neuropathy)

- Be taking any medication that, in the opinion of the Principle Investigator (PI), has potential to alter GI transit. A full list of prohibited medications is provided in the protocol. Have history or presence of any chronic lung disease

- Have presence of hepatic dysfunction, jaundice, or abnormal serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) values exceeding 2.5 x upper limit of normal

- Currently pregnant or lactating

Outcome

Type Measure Description Time frame Safety issue
Other Physical Examination Physical examination at Visits 1, 2 and 4 4 weeks
Other Vital Signs 2. Vital signs (pulse, blood pressure, temperature, and respiration rate) at Visits 1, 2 and 4 4 weeks
Other Adverse Events and Concomitant Medications Interview for adverse events (AEs) and concomitant medications at Visits 3, 4 and 5 8 weeks
Other Laboratory safety tests Laboratory safety tests including hematology, chemistry, and urinalysis at Visits 1, 2 and 4. Pregnancy test for subjects of childbearing potential at Visits 1, 2, 3, 4 and 5. 8 weeks
Primary Abdominal bloating rating Change in abdominal bloating rating, through comparison of the change in average ratings from the 7 days prior to baseline (Visit 2) to the last 7 days of the 4 week treatment period (Visit 4), between TU-100 15 g and placebo. 4 weeks
Secondary AUC for abdominal bloating ratings using lactulose challenge Change in area under the curve (AUC) for abdominal bloating ratings obtained during the lactulose challenge at Visit 2 (baseline) and at Visit 4 (4 weeks). The data are collected at -0.5, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8 hours after taking test meal (lactulose). Baseline and 4 weeks
Secondary Abdominal bloating ratings Change in the average of abdominal bloating ratings from the 7 days prior to baseline to the 7 days prior to Visit 3 (2 weeks) and to Visit 5 (8 weeks) 4 weeks
Secondary Overall IBS Severity Change in Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) total score from baseline to Visits 3, 4, and 5 4 weeks
Secondary GI symptom ratings Change in the average of GI symptom ratings from the 7 days prior to baseline to the 7 days prior to Visit 3 and to Visit 5 4 week
Secondary Quality of Life effect Change in IBS-QOL score from baseline to Visits 3, 4, and 5 4 weeks
Secondary Mood symptom ratings Change in the average of mood symptom ratings from the 7 days prior to baseline to the 7 days prior to Visit 3 and to Visit 5 4 weeks
