Comparison of Aclidinium Bromide and Formoterol Fumarate in Patients With Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD)
Comparison of Aclidinium Bromide and Formoterol Fumarate in Patients With Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD)
This exploratory study will compare the efficacy of the fixed-dose combination (FDC) of
 aclidinium bromide and formoterol fumarate once daily in the morning and placebo once in the
 evening vs. the FDC once daily in the morning and formoterol fumarate once in the evening vs.
 formoterol fumarate twice daily. The study will assess pulmonary function and symptoms in
 patients with moderate to severe COPD.
