Efficacy and safety of indacaterol/glycopyrronium in Japanese patients with COPD: Pooled analysis of SHINE and ARISE

Abstract

Background: To better evaluate the efficacy and safety of the indacaterol/glycopyrronium (IND/GLY) fixed-dose combination versus tiotropium in Japanese patients, a pooled data analysis was conducted from the SHINE and ARISE studies, which were part of the IND/GLY clinical trial program.

Methods: Japanese patients with moderate-to-severe COPD were included in the analysis. Efficacy in terms of pre-dose forced expiratory volume in one second (FEV₁) at Week 12 and Week 24/26 (ARISE/SHINE) and FEV₁ at 30min and 60min post-dose at Day 1, Week 12, and Week 24/26 was evaluated. Health status using the St. George׳s Respiratory Questionnaire (SGRQ) score, rescue medication use (number of puffs/day), safety, and tolerability were also assessed.

Results: In total, 340 patients (IND/GLY, n=161; IND, n=41; GLY, n=40; tiotropium, n=79; and placebo, n=19) were included in the analysis that focused on comparing IND/GLY versus tiotropium since they were included in both studies. At Week 12 and Week 24/26, pre-dose FEV₁ was significantly improved with IND/GLY compared with tiotropium (treatment differences=70mL and 80mL, respectively; both P≤0.001). FEV₁ at 30min and 60min post-dose, the SGRQ total score, and rescue medication use were more statistically significant with IND/GLY than with tiotropium for all assessed time-points. The overall incidence of adverse events (AEs) and serious AEs was similar between the IND/GLY- and tiotropium-treated groups.

Conclusions: Compared to tiotropium, IND/GLY provided significant improvements in lung function, health status, and rescue medication use, while having a good safety profile in Japanese patients with moderate-to-severe COPD.
