Long-term safety of tiotropium/olodaterol Respimat<sup>®</sup> in patients with moderate-to-very severe COPD and renal impairment in the TONADO<sup>®</sup> studies

Introduction: The safety, lung function efficacy, and symptomatic benefits of combined tiotropium and olodaterol in patients with COPD were established in the 1-year TONADO (R) studies (NCT01431274; NCT01431287). As tiotropium is predominantly excreted by the kidneys, the long-term safety profile of tiotropium/olodaterol was investigated in patients with renal impairment in a prespecified safety analysis of the TONADO studies. Methods: These were 2 replicate, randomized, double-blind, parallel-group, 52-week Phase III studies that assessed tiotropium/olodaterol compared with tiotropium or olodaterol alone (all via Respimat (R)) in patients with moderate-to-very severe COPD. In this analysis…
