Summary

This trial tests a new drug, ensifentrine, to see if it's effective in treating asthma. Patients will receive the drug and a placebo at different times during the study, and researchers will compare the results.

Who is the study for?
This trial is for COPD patients aged 40-80 who have a history of smoking and moderate to severe lung function impairment. They must be using regular bronchodilator therapy, able to use a nebulizer correctly, and produce sputum samples. Exclusions include significant liver enzyme elevations, recent cancer (except certain skin cancers), immunodeficiency, recent experimental drug/device use or other serious health issues.
What is being tested?
The study tests the effect of ensifentrine versus placebo on inflammation in COPD patients. It's a double-blind study where participants receive both treatments across two periods totaling up to 24 weeks with seven clinic visits. Ensifentrine is administered twice daily via nebulization.
What are the potential side effects?
While specific side effects are not listed here, potential risks may include reactions related to inhaling medication such as throat irritation or coughing, and systemic effects like headaches or gastrointestinal discomfort.
