  • Pre-BD FEV1/FVC < 0.7 at Visit 1 and pre- and post-BD FEV1/FVC < 0.7, and post-BD FEV1 ≥ 25% to < 80% of predicted normal at Visit 2
  • Documented history of ≥ 2 moderate or ≥ 1 severe COPD exacerbations in the 12 months prior to screening

  • Negative pregnancy test at Visit 1 and Visit 3 for Women Of Child-Bearing Potential (WOCBP)

Who cannot take part

  • Clinically important pulmonary disease other than COPD (eg, asthma [current diagnosis per GINA or other accepted guidelines], active pulmonary infection, clinically significant bronchiectasis when bronchiectasis is the predominant diagnosis, pulmonary fibrosis, cystic fibrosis, hypoventilation syndrome associated with obesity, lung cancer, alpha-1 antitrypsin deficiency or primary ciliary dyskinesia)

  • Participants with history of HIV infection or who test positive for HIV
  • History of lung volume reduction surgery
  • Current or history of malignancy within 5 years before the screening visit
  • Radiological findings suggestive of a respiratory disease other than COPD that is significantly contributing to the participant’s respiratory symptoms
  • Any unstable disorder, including, but not limited to, CV, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, psychiatric disorder, major physical and/or cognitive impairment
  • Unstable angina, acute coronary syndrome/acute myocardial infarction or coronary intervention with percutaneous coronary intervention/coronary artery bypass graft within 6 months of randomisation, uncontrolled arrhythmia, or cardiomyopathy, clinically significant aortic stenosis, or signs of pulmonary oedema or volume overload
  • Pulmonary arterial hypertension, either idiopathic or due to connective tissue or thromboembolic disease
  • History of another underlying condition that predisposes the participant to infections
  • History of ulcerative colitis, Crohn’s disease, or microscopic colitis diagnosed by either a gastroenterologist or by histopathology
  • Significant left heart failure (ie, NYHA class III and IV or LVEF < 40% on echocardiogram or cardiac MRI
  • Abnormal laboratory findings (ALT or AST, TBL, Hb, WBC < LLN, neutrophil count, estimated glomerular filtration rate, platelet count)
