• Inclusion Criteria:
• • 1. Participant is a male or female 40 years of age or older.

• • A highly effective method of birth control is defined as one that results in a low failure rate (i.e. \<1% per year) when used consistently and correctly, such as condom + diaphragm, condom + spermicide, diaphragm + spermicide, or intrauterine device \[IUD\] with documented failure rate of \<1% per year, or oral/injectable/implanted hormonal contraceptives used in combination with an additional barrier method.
• • 4. Participant has a diagnosis of COPD, specifically, a post-ipratropium FEV1/FVC ratio \<0.7.
• • 5. Participant has a post ipratropium 30% ≤ FEV1 \< 50% of predicted normal (using National Health and Nutrition Examination Survey-predicted equations) and absolute FEV1 \> 500 mL, or FEV1 \<30% predicted normal and absolute FEV1 \> 700 mL.
• • 6. Participant has a PIFR \<60 L/min as measured by an In-Check™ device with resistance set to DISKUS at Visit 1A (if not combined with Visit 1B) and \< 55 L/min as measured by an In-Check™ device with resistance set to DISKUS at Visit 1B and Visit 2 prior to randomization.
• • 7. Participant is capable of performing reproducible spirometry maneuvers (and plethysmography maneuvers for a subset of participants) as described by current American Thoracic Society (ATS) Guidelines.
• • 8. Participant is an active or former smoker with a cigarette smoking history (or equivalent for cigar or pipe smoking history) of at least 10 pack-years.

• Exclusion Criteria:
• • 1. Participant has a concurrent disease or condition that, in the opinion of the investigator, would interfere with study participation or confound the evaluation of safety and tolerability of the study drug.
• • 2. Participant has a history of reactions or hypersensitivity to inhaled or nebulized anticholinergics.
• • 3. Participant suffers from any medical condition that would preclude the use of inhaled anticholinergics, including narrow-angle glaucoma, symptomatic benign prostatic hyperplasia, bladder neck obstruction, or urinary retention.
• • 4. Participant has Moderate to Severe Hepatic impairment (Child-Pugh B or C) or Severe Renal Insufficiency (i.e. a glomerular filtration rate \<30 mL/min/1.72m\^2).
• • 5. Participant has been hospitalized for COPD or pneumonia within 8 weeks prior to Visit 1.
• • 6. Participant is receiving a LABA or LABA/inhaled corticosteroid (ICS; either QD or BID) at a dose that has been stable for ≤ 30 days prior to screening.
• • 7. Participant has used systemic corticosteroids within 8 weeks of Visit 1.
• • 8. Participant has used antibiotics for respiratory tract infections within 8 weeks of Visit 1, or is using antibiotics prophylactically.
• • 9. Participant received COVID-19 vaccine within 2 weeks prior to Visit 1.
