Study Description

Brief Summary

This will be a 3 part study to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and repeat doses of GSK2862277 administered via inhalation (IH) or intravenous (IV) routes in healthy subjects.

Part 1 of this study will involve an initial assessment of safety, tolerability and pharmacokinetics of GSK286227, via single escalating intravenous doses, compared to a predecessor molecule, GSK1995057. After completion of Part 1 an interim data review will occur which will assess key comparability criteria to inform progression to Part 2 of the study.

Part 2 of the study will involve single doses of GSK2862277 at a level predicted to be at or close to therapeutic dose levels. Part 2 will investigate both intravenous and inhaled routes of administration, in sequential manner, respectively. An interim data review will also occur after completion of Part 2, where all data accumulated previously will be assessed to examine appropriateness to progress to Part 3.

Part 3 of the study will involve 5 days of repeat dosing via both inhaled and intravenous routes using the same dose administered in Part 2.
