Title: A Randomized, Double-blind, Placebo-controlled, Parallel Group Trial Assessing the Rate of Decline of Lung Function With Tiotropium 18 mcg Inhalation Capsule Once Daily in Patients With Chronic Obstructive Pulmonary Disease (COPD).
Brief Summary: The primary objective of this trial is to determine whether daily treatment with tiotropium (Spiriva®, Bromuro de Tiotropio®) inhalation capsule via HandiHaler® reduces the rate of decline in lung function over time in patients with COPD.


Options:
A: Inclusion Criteria:

1. All patients must have a diagnosis of chronic obstructive pulmonary disease (COPD) and must meet the following criteria at Visit 1:

   Patients must have relatively stable, moderate to very severe airway obstruction with a post-bronchodilator FEV1 \<=70% of predicted normal and FEV1 \<=70% of FVC post-bronchodilator (i.e. 30 minutes after inhalation of 4 puffs of 100 µg salbutamol or equivalent SABA). Predicted normal values will be calculated according to ECSC.

   For Height measured in inches Males: FEV1 predicted (L) = 4.30 x (height (inches) / 39.37)-0.029 x age (yrs) - 2.49 Females:FEV1 predicted (L) = 3.95 x (height (inches) / 39.37)-0.025 x age (yrs) - 2.60 For Height measured in metres Males: FEV1 predicted (L) = 4.30 x (height (metres)) - 0.029 x age (years) - 2.49 Females: FEV1 predicted (L) = 3.95 x (height (metres)) - 0.025 x age (years) - 2.60
2. All patients must sign an informed consent consistent with ICH-GCP guidelines prior to participation in the trial.
3. Male or female patients 40 years of age or older.
4. Patients with a history of at least one exacerbation within the past year requiring treatment with either antibiotics and/or systemic steroids and/or hospitalisation.
5. Patients must be current or ex-smokers with a smoking history of \>= 10 pack-years. (Patients who have never smoked cigarettes must be excluded.)

10. Patients with severe cardiovascular disorders.
11. Patients with a known hypersensitivity to anticholinergic drugs, beta-adrenergics, lactose or any other component of the medication delivery system.

13. Patients with untreated known hypokalaemia.
14. Patients with untreated known thyrotoxicosis.
15. Patients with brittle/unstable diabetes mellitus.
16. Patients with a history of and/or active significant alcohol or drug abuse. See exclusion criterion 1.
17. Patients who have taken an investigational drug within 30 days or six half-lives (whichever is greater) prior to Screening Visit (Visit 1).
18. Use of systemic corticosteroid medication at unstable doses (i.e less than six weeks on stable dose) or at doses in excess of the equivalent of 10 mg prednisolone per day or 20 mg every other day.
19. Pregnant or nursing women or women of childbearing potential not using a medically approved means of contraception (i.e oral contraceptives, intrauterine devices, diaphragm or subdermal implants e.g Norplant) for at least three months prior to, and for the duration of the trial.
20. Previous participation (receipt of randomised treatment) in this study.
21. Patients who are currently participating in another study.
22. Patients with any respiratory infection or COPD exacerbation in the four weeks prior to the Screening Visit (Visit 1) or during the run-in period should be postponed. In the case of a respiratory infection or COPD exacerbation during the run-in period, the latter may be extended up to four weeks.
