This is a randomized (the study medication is assigned by chance), double-blind (neither physician nor participant knows the treatment that the participant receives), placebo-controlled (an inactive substance that is compared with a medication to test whether the medication has a real effect in a clinical study), multicenter, parallel-group (each group of participants will be treated at the same time) study. Approximately 200 participants will be randomly assigned to JNJ 49095397 or placebo in the ratio 1:1. The study consists of 3 phases: screening (3 weeks), double-blind treatment (12 weeks), and follow up (4 weeks). Safety evaluations will include assessment of adverse events, vital signs, physical examination, electrocardiograms, and clinical laboratory tests which will be monitored throughout the study. The total duration of the study for each participant will be approximately 19 weeks.
The purpose of this study is to assess the effectiveness and safety of JNJ 49095397 in participants with symptomatic moderate to severe chronic obstructive pulmonary disease (COPD).
