- •4. Smoking History: Current or former cigarette smokers with a history of cigarette smoking =10 pack years at Screening (Visit 0) [number of pack years = (number of cigarettes per day / 20) × number of years smoked (eg, 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years)]. Pipe and/or cigar use cannot be used to calculate pack-year history. Former smokers are defined as those who have stopped smoking for at least 6 months prior to Visit 0. Smoking cessation programs are permitted during the study.
- •5. COPD Diagnosis: Patients with an established clinical history of COPD as defined by the American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines (Celli BR, 2004) with symptoms compatible with COPD.
- •6. COPD Symptoms: A score of =2 on the Modified Medical Research Council
- •(mMRC) Dyspnea Scale.
- •7. COPD Severity:
- •a. Pre- and Post-albuterol/salbutamol FEV1/FVC ratio of <0.70.
- •b. Post-albuterol/salbutamol FEV1 =30 % and =70% of predicted normal calculated using the National Health and Nutrition Examination Survey III (Hankinson, 1999).
- •8. Maintenance Therapy: Patients on no maintenance/background therapy or patients on stable maintenance LAMA or LABA therapy are eligible. Patients taking maintenance LAMA or LABA therapy must demonstrate stable use of the maintenance LAMA or LABA therapy for at least 3 months prior to Screening and agree to continue use for the duration of the study. Section 6.7.3 of the protocol lists the medications that are prohibited during the study and the prohibited time intervals prior to Screening. Enrollment of patients on background maintenance LAMA or LABA therapy will be capped at 50%.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 500
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 300
排除标准
- •1. History of life-threatening COPD including Intensive Care Unit admission and/or requiring intubation.
- •2. Hospitalizations for COPD, pneumonia, or Corona Virus Disease 2019 (COVID-19) in the 12 weeks prior to Screening and/or a positive COVID-19 test result indicating an active infection at Screening. Patients with COVID-19 antibodies from a previous exposure with no active infection are not excluded.
- •3. COPD exacerbation requiring oral or parenteral steroids within 3 months of Screening.
- •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.
