GW642444 asthmatic subjects safety tolerability PD and PK
Brief summary
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.
