Title: A 26-week Treatment, Multicenter, Randomized, Double Blind, Double Dummy, Placebo-controlled, Adaptive, Seamless, Parallel-group Study to Assess the Efficacy, Safety and Tolerability of Two Doses of Indacaterol (Selected From 75, 150, 300 & 600 µg o.d.) in Patients With Chronic Obstructive Pulmonary Disease Using Blinded Formoterol (12 µg b.i.d.) and Open Label Tiotropium (18 µg o.d.) as Active Controls
Brief Summary: Stage 1 of the study is designed to provide data about the risk-benefit of 4 dose regimens of indacaterol (75, 150, 300 \& 600 µg o.d.) in order to select two doses to carry forward into study Stage 2. Study Stage 2 will provide pivotal confirmation of efficacy, safety, and tolerability of the selected indacaterol doses in patients with COPD
