Study summary

Danirixin is a selective chemokine receptor antagonist being developed as a potential anti-inflammatory agent for the treatment of chronic obstructive pulmonary disease (COPD). The aim of the study is to assess the safety, tolerability and pharmacokinetics (PK) in healthy Japanese subjects over the age of 65 years (inclusive). The study will be conducted in two parts: Part 1 will be a double blind, placebo-controlled, 3-period crossover, ascending single oral dose administration of GSK1325756H (Hydrobromide Salt Tablet Formulations of Danirixin) 10, 50 and 100 milligram (mg) in the fed condition. Part 2 will be an open label, 2-period crossover, single oral dose of GSK1325756H 50 mg in fed and fasted state. This study will provide an understanding of PK of hydrobromide salt of GSK1325756 in population of healthy elderly subjects and also contribute to the selection of appropriate dosing for Phase IIa study in Japan.

Outcome measures

PrimaryNumber of Participants With Any Adverse Event (AE) and Serious Adverse Events in Part 1

AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant. Safety population comprised of all participants who took at least one dose of study treatment.

PrimaryUrine Potential of Hydrogen (pH) Analysis by Dipstick Method for Part 1

Urinary pH measurement is a routine part of urinalysis. 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 acid pH (5.0 - 6.0). Urine samples were collected for the measurement of urine pH by method up to 72 hours in Part 1. Only those participants with data available at the specified time were analyzed (represented by n=x in the category titles).

PrimaryUrine Specific Gravity Analysis by Dipstick Method for Part 1

Urinary specific gravity measurement is a routine part of urinalysis. 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. The concentration of the excreted molecules determines the urine's specific gravity. Urine samples were collected for the measurement of urine specific gravity by dipstick method up to 72 hours in Part 1. Only those participants with data available at the specified time were analyzed (represented by n=x in the category titles). Density is the mass per unit volume and has units (such as g/cm\^3), however, the specific gravity is a ratio so it has no unit.

Urine samples were collected for the measurement of urinalysis parameters by dipstick method up to 48 hours in Part 2. Only categories with significant values have been presented.

PrimaryUrine pH Analysis by Dipstick Method for Part 2

Urinary pH measurement is a routine part of urinalysis. 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 acid pH (5.0 - 6.0). Urine samples were collected for the measurement of urine pH by dipstick method up to 48 hours in Part 2.

PrimaryUrine Specific Gravity Analysis by Dipstick Method for Part 2

Urinary specific gravity measurement is a routine part of urinalysis. 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. The concentration of the excreted molecules determines the urine's specific gravity. Urine samples were collected for the measurement of urine specific gravity by dipstick method up to 48 hours in Part 2. Density is the mass per unit volume and has units (such as g/cm\^3), however, the specific gravity is a ratio so it has no unit.

Vital sign measurements included SBP and DBP at Baseline and up to 72 hours in Part 1. SBP and DBP measurements were preceded by at least 5 minutes of rest for the participant in a quiet setting without distractions and were measured in a supine position after 5 minutes rest. Baseline was defined as pre-dose assessments performed on Day 1. Change from Baseline was calculated by subtracting the post-dose-visit value from the Baseline value.

Blood samples were collected at the indicated time points after administration of study treatment to investigate the PK profile of GSK1325756H in fasted state. PK parameters were calculated by standard non-compartmental analysis using Phoenix WinNonlin Version 6.4 or higher based on actual sampling times.
