Clinical Trial Summary

72 patients with mild to moderate chronic obstructive pulmonary disease were planned to be enrolled in this study and then treated with olodaterol combined with thiotropium bromide, and thiotropium bromide, respectively, for 52 weeks. To assess the effect of the test drug on small airway remodeling in patients.


Clinical Trial Description

Studies have confirmed that thiotropium bromide combined with olodaterol can significantly improve airway inflammation, quality of life and pulmonary function in patients with stable COPD, without significantly increasing adverse reactions, which is worthy of clinical promotion. At present, there are few reports on the effect of thiotropium combined with olodaterol on airway remodeling in COPD patients, so this randomized, double-blind, parallel-controlled, single-center clinical trial was designed to compare the long-term effects of thiotropium combined with olodaterol, and thiotropium on small airway remodeling in patients with mild to moderate chronic obstructive pulmonary disease. 72 patients with mild to moderate chronic obstructive pulmonary disease were planned to be enrolled in this study. After screening examination, eligible subjects were randomly assigned to the test group or the control group in a 1:1 ratio and received olodaterol combined with thiotropium bromide, and thiotropium bromide, respectively, for 52 weeks. The effect of the test drug on small airway remodeling was assessed at 12, 26, and 52 weeks after treatment. ;
