Title: A Randomized, Double-blind, Placebo-controlled Two-year Trial to Examine the Changes in Exercise Endurance and COPD Treated With Tiotropium Once Daily (EXACTT)
Brief Summary: The objective of this study is to evaluate the effects on exercise duration of 96 weeks treatment with 18 mcg tiotropium (Spiriva HandiHaler) daily as compared to placebo, in patients with COPD.


Options:
A: Inclusion criteria

1. All patients must sign an informed consent
2. Diagnosis of COPD with specific spirometric criteria (determined at study visits)
3. Age \>= 40 years
4. Medical Research Council Dyspnoea score \>= 2
5. Current or ex-smoker with a \>= 10 pack-year smoking history
6. Ability to exercise on treadmill

Exclusion criteria

1. Significant diseases other than COPD such as history of life-threatening pulmonary obstruction, thoracotomy with pulmonary resection, interstitial lung disease, CF, pulmonary thromboembolic disease, clinically evident bronchiectasis, active tuberculosis, or known moderate to severe renal impairment
2. Clinical history of asthma
3. Use of supplemental oxygen therapy
4. Respiratory tract infection or COPD exacerbation in the 6 weeks prior to Visit 1 or during the washout period prior to Visit 3 (may randomize 6 weeks after recovery)
5. Recent history (\<= 12 months) of myocardial infarction
6. Unstable or life-threatening cardiac arrhythmia
7. Malignancy treated with radiation therapy or chemotherapy in the last 5 years
8. Pregnant or nursing women
9. Known hypersensitivity to anticholinergic drugs or any component of the study medications
10. Participation in pulmonary or cardiac rehab program within 13 weeks of Visit 1
11. Estimated life expectancy \< 2 years
12. Symptomatic prostatic hyperplasia or bladder neck obstruction
13. Known narrow-angle glaucoma
14. Any condition that is contraindicated for exercise
15. Orthopaedic, muscular, neurological or cardiac disease that would interfere with regular participation in aerobic exercise or with exercise testing
16. Body mass index \< 18 kg/m2 or \>35 kg/m2 list truncated for space
B: Diagnosis of COPD and matching the following criteria:

* Baseline 20 % \< FEV1 \< 70 % of European Community of Coal and Steel (ECCS) predicted values .
* 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.
C: Inclusion Criteria:

1. All patients must have a diagnosis of chronic obstructive pulmonary disease and must meet the following spirometric criteria:

   * Patients must have relatively stable, mild to severe airway obstruction with an FEV1 =\<70% of predicted normal and an FEV1/FVC \< 70 %.
   * Predicted normal values will be taken from the print-outs of the spirometers. Spirometers have to calibrated according to ECCS.
2. Male or female patients 40 years of age or older.
3. Patients must be current or ex-smokers with a smoking history of 10 or more than 10 pack-years. Pack Years = Number of cigarettes/day : 20 x years of smoking (Patients who have never smoked cigarettes must not be included)
4. Patients must be able to perform all study related tests, acceptable pulmonary function tests, including Peak Expiratory Flow Rate (PEFR) measurements, and must be able to maintain diary cards during the study period as required in the protocol.
5. Patients must be able to inhale medication from the HandiHaler.
6. All patients must sign an Informed Consent Form prior to participation in the trial i.e. prior to pre-study washout of their usual pulmonary medications.

Exclusion Criteria:

1. Patients with significant diseases other than COPD will be excluded. A significant disease is defined as a disease which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study.
2. Patients with a recent history (i.e., one year or less) of myocardial infarction.
3. Patients with any cardiac arrhythmia requiring drug therapy or who have been hospitalised for heart failure within the past three years.
4. Patients who regularly use daytime oxygen therapy for more than 1 hour per day and in the investigator's opinion will be unable to abstain from the use of oxygen therapy.
5. Patients with known active tuberculosis.
6. Patients with a history of cancer within the last five years. Patients with treated basal cell carcinoma are allowed.
7. Patients with a history of life-threatening pulmonary obstruction, or a history of cystic fibrosis or bronchiectasis.
8. Patients who have undergone thoracotomy with pulmonary resection. Patients with a history of thoracotomy for other reasons should be evaluated as per exclusion 1.
9. Patients with any respiratory infection in the past six weeks prior to the Screening Visit (Visit 1) or during the run-in period.
10. Patients who are currently in a pulmonary rehabilitation programme or who have completed a pulmonary rehabilitation programme in the six week prior to the Screening Visit (Visit 1).
11. Patients with known hypersensitivity to anticholinergic drugs, lactose or any other components of the inhalation capsule delivery system.
12. Patients with known symptomatic prostate hypertrophy or bladder neck obstruction.
13. Patients with known narrow-angle glaucoma.
14. Patients using oral corticosteroid medication at unstable doses (i.e., less than four weeks on a stable dose before Visit 1) or at doses in excess of the equivalent of 10 mg of prednisolone per day or 20 mg every other day.
15. 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).
16. Patients with a history of asthma, allergic rhinitis or atopy.
17. Patients with a history of and/or active significant alcohol or drug abuse.
18. Patients who have taken an investigational drug within one month prior to Screening Visit (Visit 1). A log of all subjects screened, and reasons for exclusion for those not randomised will be maintained.
D: Inclusion Criteria:

1. Male or female
2. At least 40 years old
3. Smoker or ex-smoker
4. Smoking history \> 10 pack-years
5. Forced Expiratory Volume in 1 Second (FEV1) \< 60% predicted

Exclusion Criteria:

1. Recent history of myocardial infarction, life-threatening cardiac arrhythmia or hospitalisation for cardiac failure
2. History of asthma or allergic conditions.
