Trial Outcomes & Findings for A Phase 1 Study In Japanese Subjects With Type 2 Diabetes Mellitus As Monotherapy (NCT NCT02292433)

NCT ID: NCT02292433

Last Updated: 2016-03-15

Results Overview

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 14 days after last dose that were absent before treatment or that worsened relative to pre-treatment state.

Population: Safety analysis set included all participants who received at least 1 dose of study medication (including placebo) in at least 1 period.

A hypoglycemic event (HAE) was identified by characteristic symptoms or blood glucose levels. HAE was defined as 1 of the given definitions: 1) Characteristic symptoms of HAE with no home glucose monitoring performed where clinical picture included prompt resolution with food intake, subcutaneous glucagon, or intravenous glucose; 2) Characteristic symptoms of HAE with home glucose monitoring measurement of less than or equal to (=\<) 70 milligram per deciliter (mg/dL) using sponsor-provided, plasma-referenced, home glucometers (or central laboratory); 3) any glucose value =\<49 mg/dL using sponsor-provided, plasma-referenced, home glucometers (or central laboratory) with or without accompanying symptoms.

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the oral bioavailability. It is calculated as the total oral daily dose divided by AUC24, where AUC24 is the area under the plasma concentration-time profile from time 0 to 24 hours.

Terminal half-life is the time measured for the plasma concentration to decrease by one half. Terminal half-life is calculated by dividing the natural logarithm to the base e (Log e) multiplied by (\*) 2/k el, where 'k el' is the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve. Only those data points judged to describe the terminal log-linear decline were used in the regression.

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose is influenced by the oral bioavailability. It is calculated as the total oral daily dose divided by AUC24\* k el, where AUC24 is the area under the plasma concentration-time profile from time 0 to 24 hours and terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve.

SECONDARY outcome

Timeframe: Pre-morning meal (pre-breakfast), 5 hours (pre-lunch), 11 hours (pre-dinner) after morning meal on Day 0 (Baseline); pre-morning dose (pre-breakfast), 5 hours (pre-lunch), 11 hours (pre-dinner) post-morning dose on Day 7

Population: PD analysis population included all randomized participants who received at least 1 dose of study medication and had both a baseline and a post-baseline assessment for at least 1 PD parameter in at least 1 period.

Time-matched change from baseline in pre-meal serum insulin on Day 7 of each period was analyzed. Pre-meal insulin levels therefore, pre-breakfast, pre-lunch, and pre-dinner were analyzed.
