Brief 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.
