A Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single and Repeat Doses of RV6153

A Randomized, Double Blind, Placebo-controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Treatment With Single and Repeat Doses of Inhaled RV6153 in Healthy Subjects and Subjects With Stable Asthma.

Safety and tolerability of single and repeat doses assessed by spirometry	Pulmonary function test measured from forced expiratory volume in 1 second (FEV1). Pulmonary function test will be repeated until three technically acceptable measurements have been made.	Up to 29 days post final dose
Safety and tolerability of single and repeat doses by assessment of clinical laboratory tests	Clinical laboratory tests include haematology, clinical chemistry, urinalysis and additional parameters	Up to 29 days post final dose
Pharmacodynamic (PD) effect of repeat doses of RV6153 assessed by sputum cell biomarkers	Sputum samples will be collected to evaluate PD effects of repeat doses of RV6153 by assessment of phosphatidylinositol biphosphate (PIP2) and phosphatidylinositol triphosphate (PIP3).
