BENTEN Study: Changes in Symptom and Quality of Life in Patients With Uncontrolled Asthma Treated With Budesonide/Glycopyrronium/Formoterol Fumarate Metered Dose Inhaler (BGF MDI): a Prospective, Multi-centers, Observational Study

This is a single arm, prospective non-interventional study with primary data collection in patients initiated BGF MDI treatment as part of routine clinical care. In this study, 200 patients will be enrolled from approximately 20 sites mainly in general hospitals with respiratory/allergy/asthma specialists in Japan.
