Efficacy and Safety of Oral Roflumilast Taken Once Daily in Patients Older Than 40 Years With Chronic Obstructive Pulmonary Disease (BY217/M2-119)

The JADE Study: A 12-week, Double-blind, Randomized Study to Investigate the Effect of 500 mcg Roflumilast Tablets Once Daily Versus Placebo on Pulmonary Function in Patients With Chronic Obstructive Pulmonary Disease

The aim of the study is to compare the effect of roflumilast on lung function in patients with COPD. Roflumilast will be administered orally once daily in the morning at one dose level. The study duration consists of a baseline period (4 weeks) and a treatment period (12 weeks). The study will provide further data on safety and tolerability of roflumilast.
