• Able and willing to give written informed consent

COPD subjects

• Male and female subjects, aged 40-80 years, inclusive. Women will be considered for inclusion if they are: Not pregnant, as confirmed by pregnancy test (see flow chart), and not nursing.

Exclusion Criteria:

Healthy volunteers

• 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, 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 pain relief, oral contraceptive medication, hormonal replacement therapy, dietary and vitamin supplements
• Clinically relevant history of allergy as judged by the investigator
• Intolerance against standard medication used during bronchoscopy, e.g. lidocaine, midazolam.
• Infections of the lower respiratory tract within 6 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.
• HIV (Type I + Type II), hepatitis B or C, tuberculosis, or Sars-CoV-2 positive or not performed at visit 1
• 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, 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, 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. Explicitly allowed is treatment with short-acting beta-2-agonists (SABA)/long-acting beta-2-agonists (LABA)/long-acting muscarinic-antagonists (LAMA), paracetamol for pain relief, oral contraceptive medication, hormonal replacement therapy, dietary and vitamin supplements. Not allowed are inhaled corticosteroids.
• Clinically relevant history of allergy as judged by the investigator.
• Intolerance against standard medication used during bronchoscopy, e.g. lidocaine, midazolam.
• Infections of the lower respiratory tract within 6 weeks prior to screening.
• Infections of the upper respiratory tract within 2 weeks prior to screening
• Exacerbation of COPD (treatment with oral or parenteral antibiotics and/or oral or parenteral glucocoterticosteroids (GCS) and/or hospitalization related to COPD) within 60 days of visit 1.
• Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, 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.
• HIV (Type I + Type II), hepatitis B or C, tuberculosis, or Sars-CoV2 positive or not performed at visit 1.
• Positive drug screen for methadone, cannabis, opiates, cocaine metabolites, amphetamines, barbiturates and benzodiazepines at visit 1.
