Criteria

Inclusion Criteria:

Inclusion Criteria-Healthy non-smokers

  • Non-smoking volunteer
  • aged 40 -75 years (age matched to COPD patients)
  • Normal spirometry (normal FEV1/FVC ratio >70% and FEV1>80% predicted)
  • Subjects are able to give informed consent

Inclusion Criteria-COPD patients (stage II-III according to the GOLD guidelines)

  • Current and/or ex-smokers with no less than 10 pack-year smoking history
  • aged 40 -75 years
  • FEV1 greater than or equal to 30% and less than 80% of predicted (the upper value is a prostbronchodilator value)
  • FEV1/FVC < 70%
  • Patients with stable COPD
  • Inhaled Corticosteroid (ICS) treatment, if exists, must be stopped for 2 weeks prior the study treatment
  • Long-acting beta2-agonists and theophylline need to be stopped at least 3 days before run-in , but anti-cholinergics will be allowed throughout the study
  • The subjects are able to give informed consent

Exclusion Criteria:

Exclusion Criteria-Healthy non-smokers

  • Pregnancy, breast-feeding or planned pregnancy during the study. Fertile women not using acceptable contraceptive measures, as judged by the investigator
  • Upper respiratory infection within the last 4 weeks
  • Subjects who have received research medication within the previous one month
  • Subjects unable to give informed consent
  • Any psychiatric condition rendering the patient unable to understand the nature, scope and possible consequences of the study.

Exclusion Criteria-COPD patients

  • Evidence of asthma
  • Bronchodilator reversibility > 12%
  • Pregnancy, breast-feeding or planned pregnancy during the study. Fertile women not using acceptable contraceptive measures, as judged by the investigator
  • Patients who have had oral steroids within 8 weeks prior to the screening visit.
  • Patients who are already on ICS and in which it is considered unsafe (as judged by the Investigator) to stop this treatment for the study period.
  • Patients who have had an exacerbation which required treatment with oral steroids during the last 2 months prior to the screening visit.
  • Upper respiratory infection within the last 4 weeks
  • Subjects who have received research medication within the previous one month
  • Subjects unable to give informed consent
  • Any psychiatric condition rendering the patient unable to understand the nature, scope and possible consequences of the study
  • Patients with significant co-morbidities as judged by the investigator
  • Any other respiratory disease, which is considered by the investigator to be clinically significant
