Inclusion Criteria:

  • Post-bronchodilator Forced Expiratory Volume in 1 Second (FEV1) <80% and ≥30% of the predicted normal value.
  • Post-bronchodilator FEV1/Forced Vital Capacity (FVC) < 70%, where FVC is forced vital capacity ('Post-' refers to 15-30 minutes after inhalation of 400 μg of salbutamol at Visit 2)

Exclusion Criteria:

• Pregnant / nursing women or women of child-bearing potential
• Long term oxygen therapy (more than 15 hours per day) on a daily basis for chronic hypoxemia
• Patients hospitalized for COPD exacerbation in 6 weeks prior to Visit 2 and up to Visit 3

• Concomitant pulmonary disease, pulmonary tuberculosis (unless chest x-ray confirms no longer active) or clinically significant bronchiectasis
• Any history of asthma, including: blood eosinophil count >400/mm3; onset of asthma symptoms prior to age 40 years
• History of long QT syndrome or whose QTc (Bazett's) measured at Visit 2 or Visit 3 is prolonged (>450ms for males or >470ms for females)
• Clinically relevant lab abnormalities / conditions such as (but not limited to) unstable ischemic heart disease, arrhythmia (excluding stable AF), uncontrolled hypertension, uncontrolled hypo- and hyperthyroidism, hypokalemia, hyperadrenergic state or any condition which in the investigator's opinion might compromise patient safety or compliance, interfere with evaluation, or preclude completion of the study
• Uncontrolled Type I / Type II Diabetes or blood glucose outside normal or HbA1c >8.0% of total hemoglobin measured at Visit 2
• Any patient with lung cancer or any active cancer or a history of cancer with less than 5 years disease-free survival time
• History of hypersensitivity to any of the study drugs
• Irregular day/night, waking/sleeping cycles e.g. shift workers

• Investigational drug within 30 days prior to Visit 2
• Known history of non-compliance or not able to use devices or perform spirometry
