Title: A Randomized, Blinded, Double Dummy, Multi-center, Placebo Controlled, 3 Period, Crossover Study to Assess the Effect of QVA149 (110/50 µg o.d.) on Exercise Endurance in Patients With Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD), Using Tiotropium as an Active Control.
Brief Summary: This study assessed the effect of once-daily indacaterol and glycopyrronium bromide (QVA149) on exercise endurance in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).


Options:
A: Inclusion Criteria:

1. All patients must have a diagnosis of chronic obstructive pulmonary disease (COPD) and must meet the following criteria at Visit 1:

   Patients must have relatively stable, moderate to very severe airway obstruction with a post-bronchodilator FEV1 \<=70% of predicted normal and FEV1 \<=70% of FVC post-bronchodilator (i.e. 30 minutes after inhalation of 4 puffs of 100 µg salbutamol or equivalent SABA). Predicted normal values will be calculated according to ECSC.

   For Height measured in inches Males: FEV1 predicted (L) = 4.30 x (height (inches) / 39.37)-0.029 x age (yrs) - 2.49 Females:FEV1 predicted (L) = 3.95 x (height (inches) / 39.37)-0.025 x age (yrs) - 2.60 For Height measured in metres Males: FEV1 predicted (L) = 4.30 x (height (metres)) - 0.029 x age (years) - 2.49 Females: FEV1 predicted (L) = 3.95 x (height (metres)) - 0.025 x age (years) - 2.60
