Brief Summary:
This study evaluated the effect of inhaled aclidinium bromide on exercise endurance and in reducing resting and dynamic lung hyperinflation in patients with moderate to severe COPD. It was 9 weeks in duration, consisting of; a 2-week run-in period, 6 weeks of double-blind treatment, and a 1-week follow-up phone call. All patients meeting the eligibility criteria were randomized to one of two treatment groups: aclidinium bromide or placebo.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Pulmonary Disease, Chronic Obstructive | Drug: Aclidinium Bromide Drug: Placebo | Phase 3 |
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 181 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Masking: | Triple (Participant, Investigator, Outcomes Assessor) |
| Primary Purpose: | Treatment |
| Official Title: | A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, 6-Week Clinical Study to Assess the Effect of Inhaled Aclidinium Bromide (LAS34273) 200 ug on Exercise Endurance and Lung Hyperinflation in Patients With Moderate to Severe COPD |

| Arm | Intervention/treatment |
|---|---|
| Experimental: Aclidinium |
Drug: Aclidinium Bromide
Aclidinium Bromide, 200μg. Once daily oral inhalation. |
| Placebo Comparator: Placebo |
Drug: Placebo
Dose matched placebo, once daily oral inhalation. |
Primary Outcome Measures :
- Change From Baseline in Exercise Endurance Time (ET) [ Time Frame: From baseline Week 0 (Visit 4) to Week 6 (Visit 6) ]Exercise endurance time is defined as the time from the increase in work rate at 75% Wmax (watts) to the point of symptom limitation. The Wmax is defined as the highest work rate the patients were able to maintain for at least 30 seconds.
Secondary Outcome Measures :
- Trough Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: Change from baseline (Visit 4) at Week 6 (Visit 6) ]Change in trough Forced Expiratory Volume in 1 second. FEV1 was assessed at the end of the daily dosing interval (Trough).
- Trough Inspiratory Capacity (IC) [ Time Frame: Change from baseline Week 0 (Visit 4) to Week 6 (Visit 6) ]Change in trough Inspiratory Capacity. Inspiratory Capacity was measured as part of the spirometry procedures performed at each visit. IC was assessed at the end of the daily dosing interval (Trough).
- Functional Residual Capacity (FRC) [ Time Frame: Change from baseline Week 0 (Visit 4) to Week 6 (Visit 6) ]Change in trough Functional Residual Capacity. FRC was assessed at the end of the daily dosing interval (Trough).
- Inspiratory Capacity (IC)/Total Lung Capacity (TLC) Ratio [ Time Frame: Change from baseline Week 0 (Visit 4) to Week 6 (Visit 6) ]Ratio of trough Inspiratory Capacity verses Total Lung Capacity.
