Title: Multicenter, Randomized, Blinded, Placebo-controlled, Crossover, Single-dose Study to Assess the Effect of Indacaterol (150 μg) Versus Tiotropium (18 μg) on Inspiratory Capacity in Moderate Chronic Obstructive Pulmonary Disease (COPD) Patients
Brief Summary: This study compared the effects of a single dose of indacaterol with that of a single dose of tiotropium on inspiratory capacity.


Options:
A: 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:

* Smoking history of at least 20 pack years
* Post-bronchodilator Forced Expiratory Volume in 1 second (FEV1) \< 80% predicted and \>or= 30% of predicted normal value
* Post-bronchodilator FEV1/FVC \< 70%

("Post" defined as within 30 minutes of inhalation of 400 µg salbutamol)

Exclusion Criteria:

* Pregnant or nursing (lactating) women and women of child-bearing potential UNLESS they meet pre-specified definitions of post-menopausal or are using pre-specified acceptable methods of contraception
* Hospitalisation for COPD exacerbation in the 6 weeks prior to Visit 1 or during run-in
* Patients requiring oxygen therapy for chronic hypoxemia (typically \>15h/day)
* Respiratory tract infection within 6 weeks prior to Visit 1 and during the run-in period
* Concomitant pulmonary disease
* Asthma history (eosinophils \> 400/mm3; symptoms prior to age 40). Includes history of childhood asthma
* History of long QTc syndrome or QTc interval \> 450 ms for males and \>470 ms for females
* Patients who have a clinically significant condition or a clinically relevant laboratory abnormality
* History of reactions to sympathomimetic amines or inhaled medication
* Inability to use the dry powder devices or perform spirometry
* Irregular day/night, wake/sleep cycles, e.g. shift workers
* Certain medications for COPD and allied conditions such as long acting bronchodilators must not be used prior to Visit 1 and for a pre-specified minimum washout period
* Patients unable or unwilling to complete a patient diary

Other protocol-defined inclusion/exclusion criteria may apply.
B: 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.
C: * Diagnosis of COPD according to the European Respiratory Society (ERS) (R95-3225) and matching the following criteria:

  * Stable moderate to severe airway obstruction
  * Baseline 30 % \< FEV1 \< 65 % of European Community of Coal and Steel (ECCS) predicted values (R94-1408).
  * Baseline FEV1/SVC\< 70 %.
* Smoking history \> 10 pack-years (p.y.). A p.y. was defined as the equivalent of smoking
* One pack of cigarettes per day for one year.
* History of exacerbation in the past year.
D: Inclusion Criteria:

* Diagnosis of moderate (as classified by the Global Initiative for Chronic Obstructive Lung Disease \[GOLD\] Guidelines, 2007) chronic obstructive pulmonary disease (COPD) and:

  1. Smoking history of at least 10 pack-years.
  2. Forced expiratory volume in 1 second (FEV1) \< 80% and ≥ 50% of the predicted normal value.
  3. Post-bronchodilator FEV1/Force vital capacity (FVC) \< 0.7.

Exclusion Criteria:

* Patients who have had a COPD exacerbation requiring systemic glucocorticosteroid treatment or antibiotics and/or hospitalization in the 6 weeks prior to screening.
* Patients who have had a respiratory tract infection within 6 weeks prior to screening.
* Patients with concomitant pulmonary disease.
* Patients with alpha-1-antitrypsin deficiency.
* Patients with contraindications for tiotropium treatment.
* Patients with a history of hypersensitivity to any of the study drugs or to drugs from similar drug classes.

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