Abstract

Introduction: The superiority of tiotropium/olodaterol is demonstrated in improvement of lung function, dyspnea, lung hyperinflation, and quality of life compared with either monotherapy in patients with chronic obstructive pulmonary disease (COPD). Japanese Respiratory Society Guidelines for COPD management include improvement of exercise tolerance and daily physical activity as the treatment goals; however, there is limited evidence in Japanese patients with COPD. Methods: A protocol is developed for the VESUTO® study that investigates the efficacy of tiotropium/olodaterol fixed-dose combination (FDC) compared with tiotropium alone on inspiratory capacity (IC, volume from functional residual capacity to total lung capacity), exercise capacity, and daily physical activity in Japanese patients with COPD. Results: A total of 180 Japanese patients with COPD, aged ≥40 years will be enrolled into the double-blind, multicenter, active-controlled, crossover study (NCT02629965) and will be randomized to receive either tiotropium/olodaterol FDC or tiotropium for 6 weeks each [two puffs via RESPIMAT® (Boehringer Ingelheim, Ingelheim, Germany) inhaler in the morning]. The primary endpoint is IC at rest measured at 60 min post-dose after 6 weeks treatment. The secondary endpoints include the 6-min walk distance (6MWD) at 90 min post-dose and physical activity measured by the activity monitor in the last 2 weeks of the 6-week treatment periods. Lung function tests will also be assessed after 6 weeks treatment. A mixed-effects model repeated measures approach will be used for the primary and secondary endpoints. Conclusion: The VESUTO® study is the first randomized interventional study to investigate exercise capacity (6MWD) and physical activity measured by a 3-axis accelerometer in Japanese patients with COPD. The study could provide additional evidence of long-acting muscarinic antagonist (LAMA) + long-acting β2-agonist (LABA) combination therapy on patients’ physical activities as well as lung function. Trial registration: ClinicalTrials.gov: NCT02629965 (registered on December 1, 2015). Funding: The VESUTO study was funded by Nippon Boehringer Ingelheim Co., Ltd., Tokyo, Japan.
