Title: A 12-week, Randomised, Double-blind, Placebo-controlled, Parallel Group, Multinational, Phase IIb Dose Range Finding Study to Evaluate the Efficacy and Safety of AZD9668 Administered Orally at 3 Dose Levels to Patients With Chronic Obstructive Pulmonary Disease (COPD) on Treatment With Tiotropium
Brief Summary: The primary objective is to evaluate the dose-response relationship and efficacy of AZD9668 at 3 dose levels compared with placebo in symptomatic COPD patients by assessing effects on lung function and symptoms of COPD.
