- Known α1 antitrypsin deficiency, active lung infections (such as tuberculosis or pneumonia), and lung cancer are absolute exclusionary conditions. A patient who, in the opinion of the investigator, has any other significant respiratory condition in addition to COPD should be excluded. Examples may include clinically significant noncystic bronchiectasis, pulmonary hypertension, sarcoidosis, or interstitial lung disease. Allergic rhinitis is not exclusionary.
