Assessment of Switching From Salmeterol/Fluticasone to Indacaterol/Glycopyrronium in a symtomaticCOPD Patient Cohort

A 12-week Treatment, Multi-center, Randomized, Double-blind, Double-dummy, Parallel Group Study to Assess the Efficacy and Safety of Switching From Salmeterol/Fluticasone to QVA149 (Indacaterol Maleate/Glycopyrronium Bromide) in Symptomatic COPD Patients

This study will investigate whether switching symptomatic COPD patients from a fixed-dose combination of salmeterol/fluticasone 50/500 µg b.i.d. to a fixed dose combination of QVA149 110/50 µg o.d. leads to improved lung function and airflow. It will also assess the effect on symptom burden, breathlessness, and use of rescue medication after this switch.

Inclusion Criteria:

• Written informed consent must be obtained before any assessment is performed.
• Male and female ≥ 40 years

• Confirmed diagnosis of COPD and post-bronchodilator FEV1 ≥ 30% and < 80% of the predicted normal value and post-bronchodilator FEV1/FVC < 0.70 at visit 1
• Treated with salmeterol/fluticasone 50/500 µg b.i.d. for at least 3 months prior to visit 1
• Documented CAT score of ≥ 10 at Visit 1 and 2

• Respiratory tract infection within 4 weeks prior to Visit 1
• Respiratory tract infection between Visit 1 and 2. Patients can be re-screened 4 weeks after resolution of the infection
• Requiring oxygen therapy prescribed for >12 hours per day
• Onset of respiratory symptoms, including a COPD diagnosis prior to age 40 years
