Study Summary

This study is trying to identify the right dose of a long-acting medicine called WIN378 for people with moderate - severe chronic obstructive pulmonary disease (COPD). WIN378 blocks the action of a protein called TSLP that causes inflammation in the lung and may contribute to COPD control and symptoms. The study will test how doses of WIN378 are handled by the body (pharmacokinetics) and assess the safety of the medicine and markers of COPD inflammation in exhaled breath and blood, lung function and COPD control (pharmacodynamics)
