Study Arms (4)
HNS Group
EXPERIMENTALHealthy non-smokers aged between 45-75 years
HS Group
EXPERIMENTALHealthy smokers aged between 45-75 years
FeCOPD Group
EXPERIMENTALCOPD subjects with ≥ two exacerbations within 365 days prior to the screening visit (frequent exacerbators), aged between 45-75 years

Sputum collection at Day 0 and at exacerbation visits (COPD subjects)
Eligibility Criteria
You may qualify if:

- Baseline post-bronchodilator Forced Expiratory Volume of air in one second (FEV1) \> 85% of predicted normal values and baseline post-bronchodilator FEV1/Forced expiratory Vital Capacity (FVC) \> 70% of predicted normal values.
- Free of obvious health problems as established by medical history and clinical examination before entering into the study.
- Non-smokers: subjects who never smoked OR
- Smokers: current smoker having a smoking history ≥ 10 pack-years.
- COPD subjects (frequent and non-frequent exacerbators)
- Subjects who the investigator believes can and will comply with the requirements of the protocol.
- A male or female between, and including 45 and 75 years of age at the time of consent.
- Written informed consent obtained from the subject.
- Baseline post-bronchodilator FEV1 \< 80% and \>30% of predicted normal values and baseline post-bronchodilator FEV1/FVC \< 70% of predicted normal values.
- Current or former smoker having a smoking history of ≥ 10 pack-years.
