Brief Summary
This study will assess the safety and efficacy of fixed dose combinations of ensifentrine with two different glycopyrrolate dose levels compared to placebo and to the individual components of the fixed dose combinations, each administered twice a day via standard jet nebulizer, in adult subjects with chronic obstructive pulmonary disease (COPD).

Eligibility Criteria
You may qualify if:
- Males are eligible to participate if they agree to use contraception or abstinence, and refrain from donating fresh unwashed semen during the study and for at least 30 days post-study
- Females are eligible to participate if they are not pregnant, breastfeeding and if one of the following conditions apply:
- Not a woman of child-bearing potential OR
- Agrees to follow the contraceptive guidance from screening throughout the study and for at least 30 days post-study
- Agrees not to donate eggs for the purpose of reproduction from screening throughout the study and for at least 30 days post-study
- Current of former cigarette smokers with a history of smoking ≥ 10 pack years at the time of signing informed consent \[number of pack years = (number of cigarettes per day / 20) Ă— number of years smoked (e.g., 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years)\]. 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 signing informed consent. Smoking cessation programs are permitted during the study
- Subjects with an established clinical history of COPD as defined by the American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines with symptoms compatible with COPD
- A score of ≥ 2 on the Modified Medical Research Council (mMRC) Dyspnea Scale at the Screening Visit
- Post-bronchodilator (4 puffs of albuterol) spirometry during the Screening Period demonstrating both the following:
- FEV1/forced vital capacity (FVC) ratio of \< 0.70 AND
- FEV1 ≥ 30 % and ≤ 70% of predicted normal
- A posterior-anterior chest x-ray (CXR) during the Screening Period or within 12 months of signing the Informed Consent Form (ICF) showing no clinically significant abnormalities unrelated to COPD. If a CXR within the past 12 months is not available but a computed tomography (CT) scan within the same time period is available, the CT scan may be reviewed in place of a CXR
- Subjects on no maintenance/background therapy or subjects on stable maintenance as either long-acting β2-agonist (LABA) or long-acting β2-agonist/Inhaled corticosteroid (LABA/ICS) therapy are eligible. Subjects taking maintenance therapy must demonstrate regular use of maintenance therapy, in any form, for at least 60 days prior to signing informed consent and agree to continue use of their current permitted LABA or LABA/ICS medication for the duration of the screening and treatment period
- Capable of withholding from short-acting bronchodilators for 4 hours prior to spirometry testing. Subjects receiving maintenance therapy with a LABA or LABA/ICS must be capable of withholding twice-daily maintenance therapy for 24 hours and once-daily maintenance therapy for 48 hours prior to initiation of any spirometry
- Capable of using the study jet nebulizer correctly
- +2 more criteria
You may not qualify if:
- Concomitant clinically significant pulmonary disease other than COPD (i.e., asthma, tuberculosis, lung cancer, bronchiectasis, sarcoidosis, lung fibrosis, interstitial lung diseases, sleep apnea (unless controlled with stable continuous positive airway pressure \[CPAP\] use), known alpha-1 antitrypsin deficiency, core pulmonale or other non-specific pulmonary disease
- Within 6 months prior to randomization, a COPD exacerbation requiring hospitalization
- Within 3 months prior to randomization, use of oral or systemic therapies for COPD exacerbations (for example, oral, intravenous, or intramuscular glucocorticoids, antibiotics, theophylline, and roflumilast)
- History of life-threatening COPD, including Intensive Care Unit admission and/or requiring intubation
- Severe comorbidities including
- unstable cardiac disease (myocardial infarction within 1 year prior to randomization, unstable angina within 6 months prior to randomization, unstable or life-threatening arrhythmia requiring intervention within 3 months prior to randomization, diagnosis of New York Heart Association (NYHA) class III or IV heart disease, or
- any other clinically significant medical conditions including uncontrolled diseases (e.g., endocrine, neurological, hepatic, gastrointestinal, renal, hematological, urological, immunological, psychiatric \[e.g. untreated significant depression, anxiety or history of suicidality\], or ophthalmic diseases) that would, in the opinion of the Investigator, preclude the subject from safely completing the required tests or the study, or is likely to result in disease progression that would require withdrawal of the subject
- History of or clinically significant on-going bladder outflow obstruction or history of catheterization for relief of bladder outflow obstruction within 6 months prior to randomization
- History of narrow angle glaucoma
- History of hypersensitivity or intolerance to aerosol medications, albuterol, ensifentrine, or glycopyrrolate or any of its excipients/components, anticholinergic agents, or sympathomimetic amines
- History of or current malignancy of any organ system, treated or untreated within the 5 years prior to randomization, except for localized basal or squamous cell carcinoma of the skin
- Other significant psychiatric disease that would likely result in the subject not being able to complete the study, in the opinion of the Investigator
- Findings on physical examination that an investigator considers to be clinically significant or abnormal during the Screening Period including hematology, biochemistry, viral serology, and ECG
- Prior or current use of Ohtuvayre (ensifentrine)
- Previous lung resection or lung reduction surgery within 1-year of randomization
