-
Ability to give written informed consent in accordance with Good Clinical Practice and local regulations.
Exclusion Criteria
- Clinically significant diseases other than COPD.
- Patients with clinically relevant abnormal baseline haematology, blood chemistry or urinalysis, if the abnormality defines a disease listed as an exclusion criterion, will be excluded.
- All patients with a serum glutamic oxaloacetic transaminase (SGOT) > 80 IU/L, serum glutamic pyruvic transaminase (SGPT) > 80 IU/L, bilirubin >2.0 mg/dL or creatinine > 2.0 mg/dL will be excluded regardless of clinical condition.
