Exclusion criteria: Healthy subjects: Past or present disease, which as judged by the investigator, may affect the outcome of the study or put the subject at risk because of participation in the study. These diseases include, but are not limited to, coagulation disorders, cardiovascular disease, malignancy, hepatic disease, renal disease, haematological disease, neurological disease, psychiatric disease, endocrine disease, infectious disease, inflammatory disease or pulmonary disease (including but not confined to asthma, tuberculosis, bronchiectasis or cystic fibrosis) Regular intake of any prescribed or over the counter medication. Exceptions include paracetamol for short term pain relief, oral contraceptive medication, hormonal replacement therapy, dietary and vitamin supplements. Clinically relevant allergy against airborne allergens (such as pollen). Infections of the lower respiratory tract within 4 weeks prior to screening Infections of the upper respiratory tract within 2 weeks prior to screening Any clinically relevant abnormal findings in physical examination, clinical chemistry, haematology, urinalysis, vital signs, lung function, or ECG at Visit 1, which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, or may influence the results of the study. Positive drug screen for methadone, cannabis, opiates, cocaine metabolites, amphetamines, barbiturates and benzodiazepines at visit 1 History of drug or alcohol abuse Risk of non-compliance with study procedures Suspected inability to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study COPD subjects: Past or present disease other than COPD, which as judged by the investigator, may affect the outcome of the study or put the subject at risk because of participation in the study. These diseases include, but are not limited to, coagulation disorders cardiovascular disease, malignancy, hepatic disease, renal disease, haematological disease, neurological disease, psychiatric disease, endocrine disease, infectious disease, inflammatory disease or pulmonary disease (including but not confined to asthma, tuberculosis, bronchiectasis or cystic fibrosis).

Any clinically relevant abnormal findings in physical examination, clinical chemistry, haematology, urinalysis, vital signs, lung function, or ECG at visit 1, which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, or may influence the results of the study. Positive drug screen for methadone, cannabis, opiates, cocaine metabolites, amphetamines, barbiturates and benzodiazepines at visit 1. History of drug or alcohol abuse. Risk of non-compliance with study procedures.
