- 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 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.

- Smokers: current smoker having a smoking history ≥ 10 pack-years.
COPD subjects (frequent and non-frequent exacerbators)

- Any confirmed or suspected immunosuppressive or immunodeficient condition including human immunodeficiency virus (HIV) infection, based on medical history and physical examination.
- Serious, uncontrolled disease likely to interfere with the study findings.
- Acute disease and/or fever at the time of the Screening Visit or Visit 1, as applicable
- Receipt of immunoglobulins and/or any blood products within 90 days prior to Screening Visit.
- Receipt of interferon within 90 days prior to Screening Visit.
- History of malignancy.
- Subjects with a history of, or current, alcohol or substance abuse.
- Known history of immune-mediated disease other than COPD.
- Recent use of antibiotics or antiviral drug within 30 days prior to Screening Visit.
- Subject who experienced COPD exacerbation which required antibiotic, systemic corticosteroid or hospitalisation and which did not resolve at least one month prior to Screening Visit and at least 30 days following the last dose of oral corticosteroids.
- Chronic administration of immunosuppressants or other immune-modifying drugs within 180 days preceding screening visit.
- Subjects with very severe COPD, GOLD stage IV.
