The Effects of Inhaled Budesonide-formoterol-glycopyrronium in Moderate-to-severe COPD
- Conditions
- Pulmonary Disease, Chronic Obstructive
- Interventions
- Drug: BGF Inhalation AerosphereDrug: GFF Inhalation Aerosphere
- Registration Number
- NCT04675463
- Lead Sponsor
- ShiYue Li
- Brief Summary
The fixed-dose combination product Budesonide/Glycopyrronium/Formoterol Fumarate Inhalation Aerosol, BGF pMDI and dual combination product Glycopyrronium/Formoterol Fumarate Inhalation Aerosol , GFF pMDI are developed for maintenance treatment for patients with COPD.
There are still some unmet medical needs and evidence gaps in COPD therapy, such as could BGF Inhalation Aerosphere reverse the disease progression such like airway-remodelling? Could BGF Inhalation Aerosphere reduce inflammation in small airways? Before differences proven between medication groups, pilot study is needed.
This 52 weeks, Single-center, prospective, interventional pilot study could help discovering intervention effect of BGF and GFF on small airways through OCT measurement, which would show outcome of AEROSPHERE™ Delivery Technology on COPD patients.
- Detailed Description
The subjects eligible for this study will receive a 52-week of BGF or GFF treatment, and a 30 days follow-up telephone call after the last study drug dose.

Subject is willing and, in the opinion of the investigator, able to adjust current COPD therapy, as required by the protocol.
- Subjects are participating in other clinical research or have completed another clinical research within 3 months prior to screening.
- Significant diseases or conditions other than COPD. A significant disease or condition is defined as a disease or condition which, in the opinion of the investigator, may put the patient at risk because of participation in the study or may influence either the results of the study or the patients' ability to participate in the study
- Patients with clinical diagnosis of lung cancer, bronchiectasis, pneumoconiosis, or other single restricted ventilation.
- Severe cardiovascular, neural, hepatic, renal and hematologic diseases or malignancies that may interfere with the operation of the study.

- Patients have a current and history diagnosis of asthma, or who have a blood eosinophil count ≥600/mm3 (0.6×109/L).
- Patients with active pulmonary tuberculosis
- Patients with life-threatening pulmonary embolism, α1-antitrypsin deficiency, or cystic fibrosis
- History of pneumonectomy.
- COPD exacerbation in 4 weeks prior to the first visit (V1), or hospitalization and/or antibiotic application and/or oral or intravenous glucocorticosteroids application is required during screening stage.
- Long-term oxygen therapy, frequent use of glucocorticosteroids orally or intravenously (prednisone>10mg/d), or long-term use of antibiotics.
- Women who are pregnant or lactating or are planning to become pregnant during the course of the study, or women of childbearing potential who are not using an acceptable method of contraception.
- Planned hospitalization or blood donation during the trial.
- Known hypersensitivity or intolerance to trial drugs.
- History of chronic alcohol or drug abuse, or any other conditions that may impact compliance.
