Trial Outcomes & Findings for Study to Evaluate a Dose of Telotristat Etiprate in Male and Female With Mild, Moderate and Severe Hepatic Insufficiency and Matched Healthy Subjects (NCT NCT02683577)

NCT ID: NCT02683577

Last Updated: 2019-01-25

Results Overview

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.

Participant Flow

This was an open-label study conducted at 2 investigational sites, one in Romania and one in the Republic of Moldova. Subjects were enrolled to the study from 08 February 2016 (first subject enrolled) until 07 July 2016 (last subject completed).

Subjects enrolled into 3 hepatic functional groups: * Healthy control subjects with normal hepatic function * Mild hepatic impairment (HI) subjects (Child-Pugh \[C-P\] class A) * Moderate HI subjects (C-P class B). C-P score was summed from 5 clinical assessments of liver disease; each measure scored 1-3, with 3 indicating most severe derangement.

Healthy Control
Subjects in the healthy control group were assessed as having normal hepatic function. All subjects in each study group received a single oral dose of telotristat ethyl hippurate 500 mg (2x250 mg) on Day 1.

Subjects in the mild HI group were assessed as C-P class A (5 to 6 points on C-P scale for classification of the severity of liver disease). All subjects in each study group received a single oral dose of telotristat ethyl hippurate 500 mg (2x250 mg) on Day 1.
Moderate HI
Subjects in the moderate HI group were assessed as C-P class B (7 to 9 points on C-P scale for classification of the severity of liver disease). All subjects in each study group received a single oral dose of telotristat ethyl hippurate 500 mg (2x250 mg) on Day 1.

Population: The PK population (23 subjects overall) corresponded to all subjects who received at least one dose of study medication, without protocol violation affecting PK evaluation and who had a sufficient number of plasma concentrations to estimate the main PK parameters (Cmax, Tmax and AUC\[0-tlast\]).

Subjects in the mild HI group were assessed as C-P class A (5 to 6 points on C-P scale for classification of the severity of liver disease). All subjects in each study group received a single oral dose of telotristat ethyl hippurate 500 mg (2x250 mg) on Day 1.
Moderate HI
n=7 Participants
Subjects in the moderate HI group were assessed as C-P class B (7 to 9 points on C-P scale for classification of the severity of liver disease). All subjects in each study group received a single oral dose of telotristat ethyl hippurate 500 mg (2x250 mg) on Day 1.
All HI
n=15 Participants
The all HI group represented all subjects in either HI group (mild + moderate). All subjects in each study group received a single oral dose of telotristat ethyl hippurate 500 mg (2x250 mg) on Day 1.
