Effects of Bevespi on Ventilation and Gas Exchange Abnormalities in COPD Assessed by 129Xe MRI

• Status: Completed
• Trial end date: 2019-11-12
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine whether the new inhaler, Bevespi improves lung function. Magnetic resonance imaging (MRI) using inhaled hyperpolarized 129Xe gas, that can provide useful images of the functioning of the lung will be used as a new measure to determine change in function. The investigator anticipate these images will provide more specific information about lung disease than standard lung function tests in response to treatment.

• Phase: Phase 2/Phase 3
• Accepts Healthy Volunteers?: No
