Clinical Trial Summary

Trial to investigate the acute and chronic effect of tiotropium therapy on airway diameter in COPD patients as measured by inspiratory capacity (IC).

Recruitment information / eligibility

• Status: Completed
• Enrollment: 81
• Est. primary completion date: August 2001
• Accepts healthy volunteers: No
• Gender: All
• Age group: 40 Years to 75 Years

Eligibility

Inclusion Criteria:

• All patients must have a diagnosis of chronic obstructive pulmonary disease

• Male or female patients = 40 years of age but = 75 years old

• Patients must have a smoking history of more than ten pack-years. A pack-year is defined as the equivalent of smoking one pack of cigarettes per day for a year

• Patients must be able to perform all specified procedures and maintain records during the study period as required in the protocol

• Patients must be able to inhale medication from the HandiHaler®

• All patients must sign a Patient Informed Consent Form prior to participation in the trial i.e., prior to pre-study washout of their usual pulmonary medications

• Patients must be willing to attend an outpatient clinic on a regular basis

• Patients must be able to walk 164 feet (50 meters) during the Six Minute Walk Test

Exclusion Criteria:

• 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

• Patients with clinically significant abnormal baseline haematology, blood chemistry or urinalysis test results, if the abnormality defines a disease listed as an exclusion criterion

• Patients with a serum glutamic-oxaloacetic transaminase (SGOT) =1.5 x Upper Limit of Normal Range (ULN), serum glutamic-pyruvic transaminase (SGPT) =1.5 x ULN, bilirubin =1.5 x ULN or creatinine = 1.5 x ULN regardless of the clinical condition

• Patients with a recent history (i.e., one year or less) of myocardial infarction

• Patients with a recent history (i.e., three years or less) of heart failure, pulmonary edema or patients with any cardiac arrhythmia (with or without symptoms)

• Patients with regular use of daytime oxygen therapy

• Patients with known active tuberculosis

• Patients with a history of cancer within the last five years. Patients with treated basal cell carcinoma are allowed

• Patients with a history of life-threatening pulmonary obstruction, or a history of cystic fibrosis or bronchiectasis

• Patients who have undergone thoracotomy with pulmonary resection. Patients with a history or a thoracotomy for other reason should be evaluated as per exclusion criterion no. 1

• Patients with upper respiratory tract infection in the past six weeks prior to the Screening Visit or during the baseline period

• Patients with known hypersensitivity to anticholinergic drugs, lactose or any other components of the inhalation capsule delivery system

• Patients with known symptomatic prostatic hypertrophy or bladder neck obstruction

• Patients with known narrow-angle glaucoma

• Patients who are being treated with cromolyn sodium or nedocromil sodium

• Patients who are being treated with antihistamines (H1 receptor antagonists) or antileukotrienes and are not able to stop these medications 1 month before visit 1

• Patients using oral corticosteroid medication at unstable doses (i.e., less than six weeks on a stable dose) or at a dose in excess of the equivalent of 10 mg of prednisone per day or 20 mg every other day

• Pregnant or nursing women or women of childbearing potential not using a medically approved means of contraception

• Patients with a history of asthma, allergic rhinitis or atopy or who have a total blood eosinophil count = 600/mm3

• Patients with history of (past five years or less) and/or active alcohol or drug abuse

• Patients who have taken an investigational drug within one month or six half lives (whichever is greater) prior to Screening Period (Visit 1)

• Patients who have participated in any pulmonary rehabilitation program for COPD within 6 weeks prior to Visit 1 or throughout the study

• Limitation of exercise performance as a result of factors other than fatigue or exertional dyspnea such as arthritis in the leg, angina or claudication
