Effect of Roflumilast on Lung Function in Chronic Obstructive Pulmonary Disease (COPD) Patients Treated With Salmeterol: The EOS Study (BY217/M2-127)
Effect of Roflumilast on Lung Function in Chronic Obstructive Pulmonary Disease (COPD) Patients Treated With Salmeterol: The EOS Study (BY217/M2-127)
The aim of the study is to compare the efficacy of roflumilast on pulmonary function and
 symptomatic parameters in patients with chronic obstructive pulmonary disease (COPD) during
 concomitant administration of salmeterol. The study duration will last up to 28 weeks. The
 study will provide further data on safety and tolerability of roflumilast.
