Multicentre, prospective, non-randomised, single-arm, open label, mechanistic study to investigate the mechanism of action of BGF 160 on ventilation pattern complexity and variability

Inclusion Criteria:

• Female or male subjects aged 40-75 years inclusive at the time of enrolment (Visit 1)
• Documented history of COPD with a post-bronchodilator FEV1/FVC <0.70 and a post-bronchodilator 30 % < FEV1 <70% of predicted normal value (according to ERS 1993 reference values for spirometry ) at screening
• Smoking history > 10 pack-years
• Baseline significant dyspnea with a mMRC ≥ 2

Exclusion Criteria:

• History or current diagnosis of asthma or ACOS (asthma-COPD overlap syndrome)

• Respiratory infection or COPD exacerbation within 6 weeks (2 months if it resulted in hospitalization) prior to screening

• Clinically significant or relevant cardiovascular conditions, laboratory tests, electrocardiogram (ECG) parameters:
