Study Summary

The purpose of this study is to evaluate the efficacy and safety of ensifentrine in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).

Primary Outcome

Forced spirometry maneuvers including the FEV1 were used to assess pulmonary function. Average FEV1 AUC0-12h was defined as AUC over 12 hours of the FEV1, divided by 12 hours. Baseline FEV1 is the mean of the 2 measurements taken before study medication on the day of first dosing, that is, \<=40 minutes pre-dose on Day 1. Spirometry assessments were performed in accordance with American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines.
