Brief summary

The purpose of this study is to assess the efficacy (effectiveness) and safety of aclidinium bromide doses as compared to placebo in the treatment of moderate to severe chronic obstructive pulmonary disease. The study will be 16 weeks in duration; 2-week run-in period, 12-week double-blind treatment, and 2-week follow-up phone visit.

Interventions

Aclidinium bromide 200 μg, oral inhalation twice per day for 12 weeks of treatment

DRUGPlacebo

Dose-matched placebo, oral inhalation twice per day for 12 weeks of treatment

Participant flow

Recruitment details

Patient recruitment occurred from April to July of 2009 at 106 study sites, (100 in the United States and 6 additional sites in Canada.) A total of 99 study sites randomized patients.

Pre-assignment details

From the total of 561 patients randomized, 560 patients received at least 1 dose of double-blind treatment and therefore were included in the Safety Population. Of these patients, 559 had at least 1 postbaseline FEV1 assessment and qualified for the Intent to Treat (ITT) Population.

Change From Baseline in Morning Pre-dose Forced Expiratory Volume in 1 Second (FEV1)

Change from baseline in trough forced expiratory volume in 1 second before the morning dose of aclidinium bromide, Last Observation Carried Forward (LOCF)

Time frame: Change from Baseline to 12 weeks

Population: Of 561 patients randomized, 560 patients received at least 1 dose of double-blind treatment and therefore were included in the Safety Population. Of these patients, 559 had a baseline and at least 1 postbaseline FEV1 assessment and qualified for the Intent to Treat (ITT) Population. The primary efficacy endpoint was based on ITT population.
