Primary Outcome Measures :
  1. Assessment of Maximum Observed Plasma Drug Concentration (Cmax) for Telotristat Ethyl and Comparison Between Each HI Group and Healthy Control Group [ Time Frame: Blood samples were collected on Day 1 (pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12 hours [h] post-dose), Day 2 (24 h), Day 3 (48 h) and Day 4 (72 h). ]
    Blood was sampled for the purpose of determining pharmacokinetic (PK) parameters for total telotristat ethyl using a validated, specific, and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) bioanalytical method. The method was selective, linear, precise and accurate within the range from 0.5 to 500 nanograms per millilitre (ng/mL) for telotristat ethyl and the lower limit of quantification (LoQ) was 0.5 ng/mL. Results were derived by non-compartmental analysis of the plasma concentration-time profiles.

  2. Assessment of Time to Maximum Observed Plasma Concentration (Tmax) for Telotristat Ethyl and Comparison Between Each HI Group and Healthy Control Group [ Time Frame: Blood samples were collected on Day 1 (pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12 h post-dose), Day 2 (24 h), Day 3 (48 h) and Day 4 (72 h). ]
    Blood was sampled for the purpose of determining PK parameters for total telotristat ethyl using a LC-MS/MS bioanalytical method. The method was selective, linear, precise and accurate within the range from 0.5 to 500 ng/mL for telotristat ethyl and the LoQ was 0.5 ng/mL. Results were derived by non-compartmental analysis of the plasma concentration-time profiles.

  3. Assessment of Area Under the Plasma Concentration Time Curve From 0 to Time t Corresponding to the Last Quantifiable Concentration (AUC[0-tlast]) for Telotristat Ethyl and Comparison Between Each HI Group and Healthy Control Group [ Time Frame: Blood samples were collected on Day 1 (pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12 h post-dose), Day 2 (24 h), Day 3 (48 h) and Day 4 (72 h). ]
    Blood was sampled for the purpose of determining PK parameters for total telotristat ethyl using a LC-MS/MS bioanalytical method. The method was selective, linear, precise and accurate within the range from 0.5 to 500 ng/mL for telotristat ethyl and the LoQ was 0.5 ng/mL. Results were derived by non-compartmental analysis of the plasma concentration-time profiles.

  4. Assessment of Area Under the Plasma Concentration Time Curve From Time 0 to Infinity (AUC[0-inf]) for Telotristat Ethyl [ Time Frame: Blood samples were collected on Day 1 (pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12 h post-dose), Day 2 (24 h), Day 3 (48 h) and Day 4 (72 h). ]
    Blood was sampled for the purpose of determining PK parameters for total telotristat ethyl using a LC-MS/MS bioanalytical method. The method was selective, linear, precise and accurate within the range from 0.5 to 500 ng/mL for telotristat ethyl and the LoQ was 0.5 ng/mL. Results were derived by non-compartmental analysis of the plasma concentration-time profiles. AUC(0-inf) was not determined when the apparent terminal elimination half-life (t1/2) could not be determined over a time interval equal to at least 2 times t1/2 and/or the adjusted coefficient of determination value was inferior to 0.7 and/or extrapolated AUC was greater than 20%.

  5. Assessment of Cmax for LP-778902 (Active Metabolite) and Comparison Between Each HI Group and Healthy Control Group [ Time Frame: Blood samples were collected on Day 1 (pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12 h post-dose), Day 2 (24 h), Day 3 (48 h) and Day 4 (72 h). ]
    Blood was sampled for the purpose of determining PK parameters for LP-778902 (active metabolite of telotristat ethyl) using a LC-MS/MS bioanalytical method. The method was selective, linear, precise and accurate within the range from 2 to 2000 ng/mL for LP-778902 and the LoQ was 2.0 ng/mL. Results were derived by non-compartmental analysis of the plasma concentration-time profiles.

  • Subjects with impaired hepatic function: Clinical diagnosis of chronic hepatic disease (stable for more than 3 months) with a documented history of underlying hepatic insufficiency and no acute episodes of illness within 30 days prior to Day -1, and no significant change in disease status (ie, up to 1 point in the Child-Pugh classification) from screening to Day -1.
  • Control subjects with normal hepatic function: Clinical laboratory test results must be strictly within the normal laboratory reference ranges for liver function, and mean corpuscular volume (MCV) or, for other parameters, deemed as not clinically significant by the investigator.

Exclusion Criteria:

  • Clinically significant illness or disease as determined by medical history, including cardiac, pulmonary, hepatic (other than reason for their hepatic impairment), biliary, Gastrointestinal (GI), endocrinologic, or renal disorders, or cancer within the last 5 years (except localised or in situ nonmelanoma skin cancer), physical examination, clinical laboratory tests, and 12-lead ECGs.
  • Receipt of any investigational agent or study drug within 30 days or 10 half-lives, whichever is longer, prior to dosing.
  • Smoking more than 20 cigarettes (eg, 1 pack) per day or equivalent (eg, e-vapour cigarette, pipe, cigar, chewing tobacco, nicotine patch, nicotine gum); unable or unwilling to refrain from smoking and tobacco use for 2 hours prior to dosing and 4 hours after dose administration.
  • History of any serious adverse reaction or hypersensitivity to any inactive component of telotristat etiprate (ie, microcrystalline cellulose, croscarmellose sodium (disintegrant), talc, silicon dioxide, and magnesium stearate (nonbovine)).
  • Existence of any surgical or medical condition that, in the judgment of the investigator and the sponsor's, medical monitor, might interfere with the absorption, distribution, metabolism, or excretion of telotristat etiprate.
  • History of any major surgery within 6 months or anticipated surgery prior to Day -1.
  • History of renal disease or significantly abnormal kidney function test.
  • History of any active infection within 30 days prior to Day 1, if deemed clinically significant by the investigator.
