Ages Eligible for Study: | 45 Years to 80 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Confirmed COPD diagnosis
- Informed Consent: Patients must give their signed and dated written informed consent to participate
- Gender: Male or female patients
- Age: ≥ 45 years of age at screening
- Produce sputum regularly (produce sputum in at least 3 months of a year)
- Able to complete questionnaires for health status and symptoms and considered able to comply with the dosing regimen.
- Severity of disease: Patients with a measured FEV1<80% of predicted normal values as determined at screening. An average of three spirometry readings will be taken.

- Patients with a history of long QT syndrome or whose QTc measured at Visit 1 is prolonged (>450 msec for males and females) as confirmed by the ECG assessor.
- Clinically relevant abnormal laboratory values at the screening assessment that could interfere with the objectives of the trial or safety of the volunteer.
