Effects of Tiotropium on Breathing Capacity and Exercise Limitation in Early Stages of Chronic Obstructive Pulmonary Disease
A Randomized, Double-blind, Placebo-controlled, 6-week, Crossover Study to Examine the Effects of Tiotropium (Spiriva® HandiHaler®, 18 µg Once Daily) on Dynamic Hyperinflation and Physical Exercise Capacity in Patients With Early Stage Chronic Obstructive Pulmonary Disease (COPD)

La description
Inclusion criteria:
For COPD subjects: Male or female, age of 40 years or older, smoking history >10 pack-years, symptomatic defined as baseline dyspnea index focal score of 9 or more and / or daily cough with production of sputum for three months per year during at least two consecutive years, diagnosis of early stage COPD according to: post-bronchodilator FEV1/FVC ratio <70%., FEV1 >/=50% post-bronchodilator predicted normal, and a decreased Inspiratory Capacity during exercise. For Age / Gender Matched Controls: Male or female, age of 40 years or older, nonsmoker, with no significant diseases.
Exclusion criteria:
Patients with a significant disease other than COPD; a significant disease is defined as a disease which, in the opinion of the investigator, may (i) put the patient at risk because of participation in the study, (ii) influence the results of the study, or (iii) cause concern regarding the patient's ability to participate in the study.
Patients with a history of asthma, Patients requiring the use of supplemental oxygen therapy, Patients who have a limitation of exercise performance as a result of factors other than fatigue or exertional dyspnoea, such as arthritis in the leg, angina pectoris, claudication or other conditions, or Patients with contraindications to exercise.
Note: Additional exclusion criteria for Age / Gender Matched Controls: Patients with a significant disease including COPD.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Change From Baseline in Inspiratory Capacity (IC) at Isotime
Délai: baseline, six weeks of treatment
|
Inspiratory capacity (IC) during CWR exercise testing measured at isotime (isotime was established during CWR exercise testing at baseline).
Isotime is the minimum exercise time among all tests.
Constant work rate exercise means the exercise is done under constant work rate.
|
baseline, six weeks of treatment
|
Mesures de résultats secondaires
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Constant Work Rate (CWR) Endurance Time
Délai: six weeks of treatment
|
CWR exercise duration calculated as the length of time of the exercise period
|
six weeks of treatment
|
|
Change From Baseline in Modified Borg Scale Ratings for Dyspnea Intensity at Isotime
Délai: baseline, six weeks of treatment
|
Modified Borg Scale is a participant rating of the intensity of dyspnea measured on a scale ranging from 0 (Nothing at all) to 10 (Maximal, most severe ever experienced).
|
baseline, six weeks of treatment
