Exclusion criteria
Exclusion criteria: Patients who meet any of the following criteria will be excluded from participating in the study: 1. Presence of diarrhea attributed to any condition(s) other than CS including, but not limited to, fat malabsorption or bile acid malabsorption 2. Presence of >12 watery BMs per day associated with volume contraction, dehydration, or hypotension compatible with a "pancreatic cholera"-type clinical syndrome, as judged by the Investigator 3. Positive stool examination for enteric pathogens, pathogenic ova or parasites, or Clostridium difficile at Screening 4. Karnofsky Performance Status =60% (see Appendix C) 5.

Presence of any clinically significant findings at Screening medical history, or physical examination (relative to patient population) that, in the Investigator's or Medical Monitor's opinion, would compromise patient safety or the outcome of the study 15. Any other clinically significant laboratory abnormality at Screening that would compromise patient safety or the outcome of the study 16. Clinically significant cardiac arrhythmia, bradycardia, or tachycardia that would compromise patient safety or the outcome of the study. 17.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the effect of telotristat etiprate versus placebo over the double-blind portion of the study on • The incidence of treatment-emergent adverse events (TEAEs) • Percent (%) change from Baseline in 24-hour urinary 5- hydroxyindoleacetic acid (5-HIAA) levels at Week 12;Secondary Objective: To evaluate the effect of telotristat etiprate versus placebo over the double-blind portion of the study on: • Change from Baseline in the number of daily bowel movements (BMs) averaged over a 12-week treatment period • Change from Baseline in stool consistency, as measured by the Bristol Stool Form Scale averaged across all time points • Change from Baseline in the number of cutaneous flushing episodes • Change from Baseline in abdominal pain averaged across all time points • Change from Baseline in the frequency of rescue short-acting, somatostatin analog (SSA) used to treat carcinoid syndrome (CS) symptoms • Change from Baseline in the number of daily BMs averaged over the 12-week treatment period and at each study week, among patients who are not on an SSA at Baseline ;Primary end point(s): The primary efficacy endpoint is the change from Baseline in the number of daily BMs averaged over a 12-week treatment period. Safety endpoints are as follows: • Incidence of TEAEs, suspected adverse reaction, AEs leading to discontinuation from the study, SAEs, and deaths • Actual and change from Baseline in clinical laboratory results • Actual and change from Baseline in vital signs results • Actual and change from Baseline in physical examinations • Actual and change from Baseline in ECG findings ;Timepoint(s) of evaluation of this end point: at each visit and the final analysis will be done at the end of the study | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary efficacy endpoints include: • Change from Baseline in stool consistency averaged across all time points • Change from Baseline in the number of cutaneous flushing episodes • Change from baseline in abdominal pain averaged across all time points • Change in the frequency of rescue short-acting SSA is used to treat CS symptoms • Change from Baseline in the number of daily BMs averaged over the 12-week treatment period and at each study week, among patients who are not on an SSA at Baseline ;Timepoint(s) of evaluation of this end point: at each visit and the final analysis will be done at the end of the study | — |
