Brief Summary
This study will assess the pharmacokinetics (PK), pharmacodynamics (PD) and safety of ensifentrine and glycopyrrolate fixed dose (FDC) product, the individual components of the FDC (ensifentrine and glycopyrrolate, each in the FDC formulation), ensifentrine 1.5 mg in the FDC formulation and ensifentrine 3 mg in the marketed formulation each administered via a standard jet nebulizer, in adult participants with chronic obstructive pulmonary disease (COPD).

Treatment B: Ensifentrine monotherapy
EXPERIMENTAL(fixed-dose combination formulation) Subjects will receive a single dose of study medication in each treatment period followed by a 7 to 9-day washout period before receiving the next treatment in the sequence they were assigned to
Treatment C: Glycopyrrolate monotherapy
EXPERIMENTAL(fixed-dose combination formulation) Subjects will receive a single dose of study medication in each treatment period followed by a 7 to 9-day washout period before receiving the next treatment in the sequence they were assigned to
Treatment D: Ensifentrine monotherapy
EXPERIMENTAL(fixed-dose combination formulation) Subjects will receive a single dose of study medication in each treatment period followed by a 7 to 9-day washout period before receiving the next treatment in the sequence they were assigned to
Treatment E: Ensifentrine monotherapy (marketed formulation)
EXPERIMENTALSubjects will receive a single dose of study medication in each treatment period followed by a 7 to 9-day washout period before receiving the next treatment in the sequence they were assigned to

Eligibility Criteria
You may qualify if:
- Males are eligible to participate if they 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 and not to donate eggs for the purpose of reproduction from screening throughout the study and for at least 30 days post-study
- Current or former cigarette smokers with a history of cigarette smoking ≥ 10 pack years as of signing the ICF \[number of pack years = (number of cigarettes per day / 20) × number of years smoked (e.g., 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years)\]. 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 the ICF. 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
- 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 ≥ 40 % and ≤ 80% of predicted normal
- A posterior-anterior chest x-ray (CXR) during the Screening Period or within 12 months prior to signing the 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
- Capable of withholding from short-acting bronchodilators for at least 4 hours if using albuterol and for at least 6 hours if using ipratropium prior to pre-dose of blinded study medication spirometry testing
- Anatomical features of peripheral veins that allow the ability to draw sufficient blood volume for all study samples
- Capable of using the study supplied jet nebulizer correctly
- Ability to perform acceptable spirometry in accordance with ATS/ERS guidelines
- Willing and able to attend all study visits and adhere to all study assessments and procedures
You may not qualify if:
- Concomitant clinically significant pulmonary disease other than COPD (e.g., asthma, tuberculosis, lung cancer, bronchiectasis, sarcoidosis, lung fibrosis, interstitial lung diseases, sleep apnea (unless controlled with stable continuous positive airway pressure 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 therapies for a COPD exacerbation (e.g., oral, intravenous, or intramuscular glucocorticoids; antibiotics; theophylline; 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)
- 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, glycopyrrolate, any excipients/components of the study medications, anticholinergic agents, or sympathomimetic amines
- History of or current malignancy of any organ system, treated or untreated within the 5 years prior to signing the ICF, 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 the Investigator considers to be clinically significant during the Screening Period
- Prior or current use of Ohtuvayre (ensifentrine)
- Previous lung resection or lung reduction surgery within 1-year of randomization
