Summary
The primary objective of the study is to confirm that at least 1 or more doses of telotristat etiprate compared to placebo is effective in reducing the number of daily bowel movements (BMs) from baseline averaged over the 12-week double-blind portion (Treatment Period) of the trial in patients not adequately controlled by current SSA therapy.
