Effect of Bronchodilation on Cycle vs Treadmill Exercise Endurance Time in COPD

Completed · Phase 4 · Has a placebo group

Conditions studied: Chronic Obstructive Pulmonary Disease

In brief

Previous studies suggest that treadmill exercise may be a more relevant exercise stimulus than the cycle ergometer to demonstrate benefits with bronchodilator therapy in patients with COPD. The hypothesis of the study is that patients with COPD will exhibit greater improvements in exercise endurance and breathlessness with arformoterol compared with normal saline during treadmill walking than with cycle exercise.

You may qualify if…

• male or female patient 50 years of age or older; diagnosis of COPD; current or ex-smoker with at least 10 pack-years of smoking; a patient-reported score for breathlessness during activities of daily living of < 9 on the self-administered computerized baseline dyspnea index; a post-bronchodilator FEV1 < 80% predicted; a post-bronchodilator FEV1/FVC ratio < 70%; and clinically stable condition.
