 · Use of immunosuppressive medications within 4 weeks prior to baseline (e.g. cyclosporine, methotrexate, TNF alpha receptors or antibodies, gold, azothiaprine)
 · Known alpha-1-antitrypsin deficiency
 · Known infection with HIV and/or active hepatitis
 · Diagnosis, treatment, or remission of any cancer (other than basal cell carcinoma) within 5 years prior to study start,
 · Clinically significant cardiopulmonary abnormalities (diagnosed clinically or by x-ray/CT-scans/ ECG) that are not related to COPD and that require further evaluation
 · Clinically relevant ECG findings (e.g. acute or recent myocardial infarction, clinically significant arrhythmia)
 · Alcohol or drug abuse
 · Suspected hypersensitivity and/or contraindication to any ingredients of the study medication (roflumilast) or rescue medication
 · Patients not able to follow study procedures e.g. language problems, psychological disorders
