Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Sputum markers of inflammation	Sputum samples will be collected to evaluate effects on inflammation by assessment of myeloperoxidase, IL-6, IL-8, TNF alpha and other exploratory parameters	Cohort 13 (subjects who smoke) only - assessments at screening and Days 1, 7 & 14	No
Primary	Safety and tolerability of single and repeat doses assessed by incidence of treatment emergent adverse events	Assessment of the number of adverse events reported by subjects following dosing	Up to 29 days post final dose	No
Primary	Safety and tolerability of single and repeat doses assessed by ECG (12-lead ECG)	12-lead ECGs will be obtained using an ECG machine that automatically calculates heart rate and measures PR, QRS, QT, and QTcB/QTcF intervals. ECGs will be measured after resting for 5 minutes	Up to 29 days post final dose	No
Primary	Safety and tolerability of single and repeat doses assessed by vital sign measurement (blood pressure & heart rate)	Blood pressure heart rate will be assessed together using an automated device after resting for 5 minutes.
