This study will evaluate efficacy (FEV1), safety, tolerability, pharmacodynamics and pharmacokinetics of single and repeat inhaled doses of GW642444. This will be a multi-centre, double-blind, placebo controlled, dose ascending, four way cross-over study in approximately 28 mild to moderate asthmatic subjects.

Key assessments: Efficacy, safety, tolerability, pharmacodynamics and pharmacokinetics will be assessed by measurement of FEV1, blood pressure, heart rate, 12-lead ECGs, clinical laboratory tests, collection of adverse events (AE) information and blood samples.
