Stool samples for the determination of total FBA were collected in 48-hour windows from 48 hours before dosing on Day 1 through Day 14. The average of daily total FBA excretion is calculated before (Day -1 and Day -2) as the first pre dose of IMP and after (Day 1-12) as the first post-dose of IMP. The FBA is calculated as Total FBA (micromoles) = FBA (micromol per liter) * weight (grams) divided by 10^3. Participants with fecal bile acid concentration and their average pre-first dose and average post-first dose were reported.
