Tiotropium + olodaterol in patients with moderate to severe COPD with chronic bronchitis and/or emphysema

Introduction: Chronic bronchitis and emphysema are two COPD phenotypes that can affect pharmacologic treatment decisions. Aims: Tiotropium (T) + olodaterol (O) was established for COPD treatment in two large Phase III trials. This post hoc analysis assessed the effect of T+O on lung function, symptoms and health-related quality of life (QoL) in patients (pts) with investigator-defined bronchitis and/or emphysema. Methods: TONADO ® 1+2 were replicate, randomised, double-blind, parallel-group trials. Pts with GOLD 2–4 COPD were randomised to once-daily T+O 2.5/5 or 5/5 µg, T 2.5 or 5 µg, or O 5 µg via Respimat ® inhaler. 1 End points included forced expiratory volume in 1 second (FEV 1 ) area…
