Video abstract of original research paper “Lung function and long-term safety of tiotropium/olodaterol in East Asian patients with chronic obstructive pulmonary disease” published in the open access International Journal of COPD by authors Bai C, Ichinose M, Lee SH, et al.

Background and purpose: While the efficacy and safety of combined tiotropium and olodaterol in patients with COPD was established in a large clinical trial program, it is important to assess whether clinical data can be applied to geographic patient groups, particularly for East Asian patients who may have a different phenotypic profile to the global trial population. This study aimed to compare the lung function and safety profiles of tiotropium/olodaterol and monocomponents in East Asian and global populations from the TONADO® trials.

Materials and methods: In the replicate, double-blind, parallel-group, active-controlled, randomized, 52-week, Phase III TONADO studies, patients received tiotropium/olodaterol, tiotropium, or olodaterol. We assessed the forced expiratory volume in 1 second (FEV1) area under the curve from 0 to 3 hours (AUC0–3) response and trough FEV1 response at 24 weeks for the approved doses, tiotropium/olodaterol 5/5 μg, tiotropium 5 μg, and olodaterol 5 μg. Treatment-emergent adverse events were recorded throughout treatment and #21 days after study medication.

Results: In the East Asian population, 1,152 patients were randomized (5,163 overall). After 24 weeks, FEV1 AUC0–3 and trough FEV1 responses were greater (P,0.0001) with tiotropium/olodaterol 5/5 μg in both populations versus tiotropium or olodaterol. The East Asian population showed slightly greater trough FEV1 treatment differences between tiotropium/olodaterol 5/5 μg and tiotropium compared to the overall population. Generally, no increase in adverse events was seen with tiotropium/olodaterol 5/5 μg compared to tiotropium and olodaterol in either population.

Conclusion: The efficacy and safety profile of tiotropium/olodaterol 5/5 μg has been demonstrated for both East Asian and global populations.
