Title: A Randomised, Double-blind, Double-dummy, Active-controlled Study Evaluating the Efficacy, Safety and Tolerability of Twice-daily Aclidinium Bromide/Formoterol Fumarate Compared With Twice-daily Salmeterol/Fluticasone Propionate for 24 Weeks Treatment in Symptomatic Patients With Chronic Obstructive Pulmonary Disease (COPD)
Brief Summary: The purpose of the study is to compare the efficacy, safety and tolerability of aclidinium bromide/formoterol fumarate and salmeterol/fluticasone propionate in patients with chronic obstructive pulmonary disease (COPD)


Options:
A: Inclusion Criteria:

* A clinical diagnosis of COPD with symptoms for more than 2 years.
* Smoking history of 10 or more pack years
* A history of at least one COPD exacerbation requiring a course of oral steroids and/or antibiotics within 1-12 months before first visit.

Non-child bearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile). Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation. Post-menopausal females are defined as being amenorrhoeic for greater than 1 year with an appropriate clinical profile, e.g., age appropriate, \> 45 years, in the absence of hormone replacement therapy. OR Child bearing potential, has a negative pregnancy test at screening, and agrees to one of the acceptable contraceptive methods used consistently and correctly (i.e., in accordance with the approved product label and the instructions of the physician for the duration of the study - screening to follow-up contact). - Diagnosis: An established clinical history of COPD in accordance with the definition by the American Thoracic Society/European Respiratory Society

* Smoking History: Current or former cigarette smokers with a history of cigarette smoking of \>=10 pack-years \[number of pack years = (number of cigarettes per day / 20) x number of years smoked (e.g. 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years both equal 10 pack-years)\]. Former smokers are defined as those who have stopped smoking for at least 6 months prior to Visit 1. Pipe and/or cigar use cannot be used to calculate pack-year history.
* Severity of Disease: A pre and post-albuterol/salbutamol FEV1/ Forced Vital Capacity (FVC) ratio of \<0.70 and a post-albuterol/salbutamol FEV1 of \>=30% and \<=70% of predicted normal values at Visit 1. Predicted values will be based upon the ERS Global Lung Function Initiative
* Dyspnea: A score of \>=2 on the Modified Medical Research Council Dyspnea Scale (mMRC) at Visit 1.
* French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category.

* Unstable or life threatening cardiac disease: Long-acting muscarinic antagonists (LAMAs) should be used with caution in subjects with severe cardiovascular disease. In the opinion of the investigator, use should only be considered if the benefit is likely to outweigh the risk in conditions such as: Myocardial infarction or unstable angina in the last 6 months; Unstable or life threatening cardiac arrhythmia requiring intervention in the last 3 months; New York Heart Association Class IV heart failure
