Brief summary:
The purpose of this study is to evaluate the efficacy, safety and tolerability of aclidinium bromide doses compared with placebo in the treatment of moderate to severe, stable chronic obstructive pulmonary disease. The study will be 56 weeks in duration; a 2-week run-in period followed by a 12-week double-blind, placebo-controlled treatment period. This will be followed by an open-label 40-week treatment period and a 2-week follow up phone call. All patients will receive the higher Aclidinium Bromide during the 40-week open label treatment period.

Detailed description:

Arms:
arm 1: Aclidinium bromide 200 μg dose twice per day, inhaled for 12 weeks of treatment At week 12, patients who were on Aclidinium bromide 200 μg will receive open label 400µg aclidinium bromide for 40 weeks arm 2: Aclidinium bromide 400 μg dose twice per day, inhaled for 12 weeks of treatment. At week 12, patients who were on Aclidinium bromide 400 μg will continue to receive open label 400µg aclidinium bromide for 40 weeks arm 3: Dose-match placebo, oral inhalation twice per day for 12 weeks of treatment. At week 12, patients who were on placebo will receive open label 400µg aclidinium bromide for 40 weeks
