Title: A Randomized, Double-blind, Placebo Controlled, Multicenter, 3-period Crossover Study to Compare the Effect of Indacaterol (150μg o.d.) on Inspiratory Capacity to Placebo in Patients With Moderate COPD, Using Open Label Tiotropium (18μg o.d.) as Active Control
Brief Summary: This study is being conducted to assess the effect of indacaterol (150 μg o.d.) on inspiratory capacity (IC), using placebo and open label tiotropium (18 μg o.d.) as comparators in patients with moderate chronic obstructive pulmonary disease (COPD). In particular, spirometric timepoints are included to elucidate the peak-IC in a period of approximately 4 hour post inhalation


Options:
A: Inclusion Criteria:

* age 40-80 years old

cases: spirometry (post-bronchodilator) based diagnosis of COPD (GOLD criteria) + smoking history of at least 10 pack-years and active smoking behavior till at least 10 years from the moment of enrollment.

smoking controls: no COPD (spirometry based) + smoking history of at least 10 pack-years and active smoking behavior till at least 10 years from the moment of enrollment.

non-smoking controls: no COPD (spirometry based) + \< 1 pack year

Exclusion Criteria:

* COPD exacerbation within 4 weeks prior to study
* Lung surgery
* Recent diagnosis of cancer
* Therapy with oral corticosteroids in the last 6 weeks
* Significant cardiovascular comorbidity
* Significant orthopedic/musculoskeletal problems
B: Inclusion Criteria:

* patients hospitalized for exacerbation of COPD

Exclusion Criteria:

* patients presenting change in mental status (confusion, lethargy or coma)
* persistence or worsening in hypoxemia (PaO2\<40mmHg) and/or respiratory acidosis (pH\<7.25) despite oxygen supplementation or use of non-invasive ventilation
* hemodynamic instability requiring vasoactive drugs
* patients transferred to ICU
* hospitalization lower than 5 days
* diseases that prevented the exercises
C: Inclusion Criteria:

* Co-operative outpatients with a diagnosis of COPD (moderate as classified by the GOLD Guidelines, 2008) and including:

  * Smoking history of at least 10 pack years
  * Post-bronchodilator FEV1 \<80% and ≥50% of the predicted normal value (Visit 2).
  * Post-bronchodilator FEV1/forced vital capacity (FVC) \<70% (Visit 2).

Exclusion Criteria:

* Patients who received any corticosteroid (including inhaled) for 3 months prior to screening

Other protocol-defined inclusion/exclusion criteria may apply
D: Inclusion Criteria:

Patients with stable COPD according to the current GOLD guidelines (GOLD 2013). Current or ex-smokers who have a smoking history of at least 10 pack years (e.g. 10 pack years = 1 pack /day x 10 yrs, or ½ pack/day x 20 yrs)..

Patients with airflow limitation indicated by a post-bronchodilator FEV1 ≥40% and \<80% of the predicted normal, and a post-bronchodilator FEV1/FVC \<0.70

Exclusion Criteria:

Patients with conditions contraindicated for treatment with, or having a history of reactions/hypersensitivity to any of the following inhaled drugs, drugs of a similar class or any component thereof, anticholinergics, long and short acting beta2 agonists, sympathomimetic amines, lactose or any of the other excipients Patients who have a clinically significant ECG abnormality at Visit 1, who in the judgment of the investigator would be at potential risk if enrolled into the study.

Patients with paroxysmal (e.g. intermittent) atrial fibrillation are excluded. Patients with persistent atrial fibrillation as defined by continuous atrial fibrillation for at least 6 months and controlled with a rate control strategy (i.e., beta blocker, calcium channel blocker, pacemaker placement, digoxin or ablation therapy) for at least 6 months may be considered for inclusion. In such patients, atrial fibrillation must be present at baseline and screening visits, with a resting ventricular rate \< 100/min.

Patients with a history of malignancy of any organ system, treated or untreated, within the past 5 years whether or not there is evidence of local recurrence or metastases, with the exception of localized basal cell carcinoma of the skin. Patients with non-melanoma skin carcinoma may be considered for the study.

Patients with a body mass index (BMI) of more than 40 kg/m2. Women who are pregnant or breast feeding Patients requiring long term oxygen therapy on a daily basis for chronic hypoxemia.

Patients who have had a COPD exacerbation that required treatment with antibiotics and/or oral corticosteroids and/or hospitalization in the 6 weeks prior to screening.

Patients who have had a respiratory tract infection within 4 weeks prior to screening.

Patients with any history of asthma. Patients with concomitant pulmonary disease Patients with clinically significant bronchiectasis. Other protocol-defined inclusion/exclusion criteria may apply
