Research Study for Chronic Obstructive Pulmonary Disease (COPD)


The purpose of this research study is to determine how safe and effective a combined investigational inhaled medication is when taken for a long period of time compared to taking the individual components of that drug in the treatment of patients with chronic obstructive pulmonary disease (COPD).
This study is for males and females at least 40 years of age who have a diagnosis of COPD and meet spirometry criteria.
