  Purpose

The main purpose of the study is to see how safe GSK1995057 is and how well it is tolerated after dosing. The study will also investigate how GSK1995057 is taken up, metabolised (chemically broken down), distributed through the body and excreted, and what some of the effects of the study drug are.

Detailed Description:

This study will be the first investigation of GSK1995057 in humans and is primarily designed to investigate safety and tolerability of single and repeat intravenously infused doses. The study will enrol healthy male subjects and healthy female subjects of non-child bearing potential and will also investigate immunogenicity, GSK1995057 distribution (pharmacokinetics), and potential impact on indicators of host immunity and normal immunological function. Safety, tolerability, immunogenicity, pharmacokinetic and pharmacodynamic data from this trial may facilitate further clinical investigations in healthy subjects dosed with GSK1995057 via the inhaled route, and ultimately clinical trials in patients with acute lung injury.
