Trial Outcomes & Findings for A Relative Bioavailability and Food-Effect Study of GSK3640254 Tablet and Capsule Formulations in Healthy Participants (NCT NCT04128293)

NCT ID: NCT04128293

Last Updated: 2020-08-25

Results Overview

Blood samples were collected at indicated time points for pharmacokinetic analysis of GSK3640254. The pharmacokinetic (PK) parameters were calculated by standard non-compartmental analysis. PK Parameter Population included all participants who underwent plasma PK sampling and had evaluable PK parameters estimated.

Participant Flow

This was a randomized, open-label, single dose, 4 period crossover study in healthy participants conducted at a single center in the United States.

A total of 16 participants were enrolled in this study. The study was early terminated by sponsor due to a potential contamination issue in the study drug after completion of treatment Period 2. Hence, treatment Periods 3 and 4 were not conducted.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. An SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect; and other important medical events which may require medical or surgical intervention. Safety Population consisted of all participants who received at least 1 dose of study medication.

Urine samples were collected to analyze the urine parameter: pH. Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acidic pH (5.0 - 6.0).

Timeframe: Baseline (Day -1) and at Day 2

Population: Safety Population.

Blood samples were collected to analyze the hematology parameters: basophils, eosinophils, lymphocytes, monocytes, neutrophils and platelet count. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits, prior to the first dose of study drug administration. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Blood samples were collected to analyze the chemistry parameters: amylase and lipase. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits, prior to the first dose of study drug administration. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Urine samples were collected to analyze the urinalysis parameter: specific gravity. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits, prior to the first dose of study drug administration. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Urine samples were collected to analyze the urinalysis parameter: pH. Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acidic pH (5.0 - 6.0). Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits, prior to the first dose of study drug administration. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Twelve-lead ECGs were obtained to measure PR Interval, QRS Duration, QT Interval, QTcF Interval and QTcB Interval. Twelve-lead ECGs were performed with the participant in a supine or semi-supine position after a rest of at least 10 minutes. Baseline was defined as the average of the triplicate pre-dose assessments within each treatment. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.
