Title: A Randomised, Double-blind, Placebo-controlled, Parallel Group Study to Determine the Effect of 12 Weeks Treatment of Orally Inhaled Tiotropium + Olodaterol Fixed Dose Combination (2.5/5 µg and 5/5 µg) Delivered by the Respimat® Inhaler, on Exercise Endurance Time During Constant Work Rate Cycle Ergometry in Patients With Chronic Obstructive Pulmonary Disease (COPD)[Torracto (TM)]
