• • 4. Previous lung resection or lung reduction surgery within 1-year of Screening.
• • 5. Long term oxygen use defined as oxygen therapy prescribed for greater than 12 hours per day. As needed oxygen use (≤12 hours per day) is not exclusionary.
• • 6. Pulmonary rehabilitation, unless such treatment has been in a stable maintenance phase for 4 weeks prior to Visit 1 and remains stable during the study.
• • 7. Lower respiratory tract infection within 6 weeks of Screening.
• • 8. Other respiratory disorders including, but not limited to, a current diagnosis of asthma, active tuberculosis, lung cancer, sarcoidosis, lung fibrosis, interstitial lung diseases, unstable sleep apnea, known alpha-1 antitrypsin deficiency, core pulmonale, clinically significant pulmonary hypertension, clinically significant bronchiectasis, or other active pulmonary diseases.
• • 9. Major surgery (requiring general anesthesia) in the 6 weeks prior to Screening, lack of full recovery from surgery at Screening, or planned surgery through the end of the study.
• 10. Historical or current evidence of clinically significant cardiovascular disease defined as any disease that in the opinion of the Investigator would put the safety of the patient at risk through participation or which could affect the efficacy or safety analysis if the disease/condition were to exacerbate during the study, including, but not limited to:
• • Myocardial infarction or unstable angina within 6 months prior to Screening.
• • Unstable or life-threatening cardiac arrhythmia requiring intervention within 3 months prior to Screening.
• • Diagnosis of New York Heart Association Class III and Class IV heart failure.

• • 20. Chest X-ray (CXR; posterior-anterior) at Screening, or in the 12 months prior to Screening with clinically significant abnormalities not attributable to COPD. If a CXR within the past 12 months is not available but a computerized tomography (CT) scan within the same time period is available, the CT scan may be reviewed in place of a CXR. For subjects in Germany, if a CXR or CT scan is not available in the 12 months prior to Screening, the subject is not eligible for the study.
