Title: A 6-Month Double-Blind, Double-Dummy, Randomized, Parallel Group, Multicenter Efficacy & Safety Study of SYMBICORT® pMDI 2 x 160/4.5 µg & 80/4.5 µg Bid Compared to Formoterol TBH, Budesonide pMDI (& the Combination) & Placebo in COPD Patients
Brief Summary: The purpose of this study is to compare a combination asthma drug (Symbicort) with its two components, budesonide and formoterol, taken individually or in combination, and with placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD)


Options:
A: Inclusion Criteria:

* A clinical diagnosis of COPD with symptoms for more than 2 years

Exclusion Criteria:

* A history of asthma

  1. Smoking history of at least 20 pack years
  2. Post-bronchodilator forced expiratory volume in 1 second (FEV1) \< 80% and ≥ 30% of the predicted normal value
  3. Post-bronchodilator FEV1/FVC (forced volume capacity) \< 70% (Post refers to within 30 minutes after inhalation of 400 μg of salbutamol)

     Exclusion Criteria:
* Patients who were hospitalized for a COPD exacerbation in the 6 weeks prior to screening.

Other protocol-defined inclusion/exclusion criteria applied to the study.
C: Inclusion criteria:

* Patients with COPD and FEV1 \<60% of predicted normal and baseline (pre-bronchodilator) FEV1/FVC ratio \<70%.
* Current or ex-smokers with a smoking history of at least 10 pack-years.

Exclusion criteria:

* Diagnosis of other respiratory disorders (including asthma).
* Requirement for long term oxygen therapy.
D: Inclusion Criteria:

Clinical diagnosis of moderate to severe Chronic Obstructive Pulmonary Disease (COPD) as per the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2006 Guidelines (mandatory) and including:
