• Pharmacokinetics samples for AZD9164 [ Time Frame: PK sampling during the residential period and intense PK sampling day 1 and 15 in healthy and day 13 in COPD patients ] [ Designated as safety issue: No ]
• Investigation of PD effects [ Time Frame: Spirometry at screening and during the residential stay ] [ Designated as safety issue: No ]

• Pharmacokinetics samples for AZD9164 [ Time Frame: PK sampling during the residential period and intense PK sampling day 1 and day 15 ] [ Designated as safety issue: No ]
• Investigation of PD effects [ Time Frame: Spirometry at screening and during the residential stay ] [ Designated as safety issue: No ]

The purpose of this study is to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of inhaled AZD9164 following administration of multiple ascending doses in healthy male and female subjects and COPD patients.

Exclusion Criteria:

• Healthy subjects; Any clinically significant disease or disorder which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, or influence the results of the subject's ability to participate in the study
• COPD patients; Any clinically significant disease or disorder (other than COPD) which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, or influence the results of the subject's ability to participate in the study
• Healthy subject and COPD patients; Any clinically significant abnormalities in clinical chemistry, haematology, urinalysis or physical examination results as judged by the investigator
• Healthy subject and COPD patients; Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG that may interfere with the interpretation of QTc interval changes
