Abstrakt: Introduction: The efficacy of tiotropium/olodaterol compared with tiotropium in patients with chronic obstructive pulmonary disease (COPD) has been demonstrated in a large clinical programme. Currently, randomised controlled trial (RCT) data on dual bronchodilation as first-line maintenance therapy are limited. In this post hoc analysis of pooled data from four RCTs, we compared the efficacy of tiotropium/olodaterol versus tiotropium as maintenance therapy in patients with COPD who were not receiving maintenance treatment with long-acting muscarinic antagonists (LAMAs), long-acting β 2 -agonists (LABAs) or inhaled corticosteroids (ICS) ("maintenance naïve") at study entry.
Methods: TONADO ®  1/2 (52 weeks) and OTEMTO ®  1/2 (12 weeks) were phase III RCTs in patients with COPD. TONADO 1/2 and OTEMTO 1/2 enrolled patients with post-bronchodilator forced expiratory volume in 1 s (FEV 1 ) < 80% predicted (lower limit FEV 1  ≥ 30% in OTEMTO 1/2 only). We examined the effect of tiotropium/olodaterol 5/5 µg versus tiotropium 5 µg on trough FEV 1 response, St. George's Respiratory Questionnaire (SGRQ) total score and Transition Dyspnoea Index (TDI) focal score at 12 weeks in four pooled studies.
Results: The pooled analysis included 1078 maintenance-naïve patients. There were significant improvements with tiotropium/olodaterol versus tiotropium in trough FEV 1 [0.056 L; 95% confidence interval (CI) 0.033, 0.079; P < 0.0001], SGRQ score (- 1.780; 95% CI - 3.126 to - 0.434; P = 0.0096) and TDI score (0.409; 95% CI 0.077, 0.741; P = 0.0158) at week 12. For patients receiving tiotropium/olodaterol, the odds of achieving a minimal clinically important difference from baseline in any of the analysed outcomes (FEV 1 ≥ 0.1 L, SGRQ ≥ 4.0 points or TDI ≥ 1.0 point) were higher versus tiotropium.
Conclusions: In patients who were maintenance naïve at baseline, treatment initiation with tiotropium/olodaterol resulted in greater improvements in lung function, health status and dyspnoea severity compared with tiotropium alone, without compromising patient safety. These results support the use of dual bronchodilation with tiotropium/olodaterol as first-line maintenance treatment in patients with COPD.
