Description

Enrolled participants will be expected to participate for approximately 7 weeks: 1 to 2 weeks for screening, 4 weeks of treatment, and 1 week of follow up. Participants will be randomized to one of 6 treatment arms: two fixed dose combinations of ensifentrine (3 mg) and glycopyrrolate (either 21.25 or 42.5 mcg), the 3 individual components as monotherapies, or placebo. All treatments will be administered twice a day via oral inhalation by a standard jet nebulizer. The primary objective of this study is to evaluate the bronchodilator effects of the fixed dose combinations compared to each of the individual components and to placebo.
