Title: A Randomized, Double-blind, Controlled, Parallel-group, 12-week Study to Compare the Efficacy and Safety of the Combination of Indacaterol 150 µg Once Daily With Open Label Tiotropium 18 µg Once Daily Versus Open Label Tiotropium 18 µg Once Daily in Patients With Moderate-to-severe Chronic Obstructive Pulmonary Disease
Brief Summary: This study assessed the efficacy and safety of indacaterol (150 µg once daily \[od\]) when combined with tiotropium (18 µg od) versus tiotropium (18 µg od) treatment alone in patients with chronic obstructive pulmonary disease (COPD).
