A Randomized, Multicenter, Open-label, Parallel-group, 12-week Study to Assess the Efficacy and Safety of Switching From Tiotropium to QVA149 (Indacaterol Maleate/Glycopyrronium Bromide) in Symptomatic Mild to Moderate COPD Patients

To demonstrate superiority of QVA149 (110/50 μg) once daily compared to tiotropium 18 μg once daily in terms of trough forced expiratory volume in 1 second (FEV1) (mean of 45 min and 15 min pre-dose) following 12 weeks of treatment in mild to moderate symptomatic COPD patients

Inclusion Criteria:

• Patients with CAT score ≥ 10 at Visit 0 and Visit 1.
• Patients who are on and have been on tiotropium monotherapy for the past 3 months.
• 0 or 1 COPD exacerbation in the previous 12 months (not leading to hospital admission).
