Abstract

Introduction: Since chronic obstructive pulmonary disease (COPD) is a heterogeneous condition, a composite endpoint of clinically important deterioration (CID) may provide a more holistic assessment of treatment efficacy. We compared long-acting muscarinic antagonist/long-acting β2-agonist combination therapy with tiotropium/olodaterol versus tiotropium alone using a composite endpoint for CID. CID was evaluated overall and in patients with low exacerbation history (at most one moderate exacerbation in the past year [not leading to hospitalisation]), Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2 patients and maintenance-naïve patients with COPD. We assessed whether early treatment optimisation is more effective with tiotropium/olodaterol versus tiotropium in delaying and reducing the risk of CID.

Methods: Data were analysed from 2055 patients treated with either tiotropium/olodaterol 5/5 μg or tiotropium 5 μg (delivered via Respimat®) in two replicate, 52-week, parallel-group, double-blind studies (TONADO® 1/2). CID was defined as a decline of at least 0.1 L from baseline in trough forced expiratory volume in 1 s, increase from baseline of at least 4 units in St. George's Respiratory Questionnaire score, or moderate/severe exacerbation. Time to first occurrence of one of these events was recorded as time to first CID.

Results: Overall, treatment with tiotropium/olodaterol significantly increased the time to, and reduced the risk of, CID versus tiotropium (median time to CID 226 versus 169 days; hazard ratio [HR] 0.76 [95% confidence interval 0.68, 0.85]; P < 0.0001). Significant reductions were also observed in patients with low exacerbation history (241 versus 170; HR 0.73 [0.64, 0.83]; P < 0.0001), GOLD 2 patients (241 versus 169; 0.72 [0.61, 0.84]; P < 0.0001) and maintenance-naïve patients (233 versus 171; 0.75 [0.62, 0.91]; P = 0.0030).

Conclusion: In patients with COPD, including patients with low exacerbation history, GOLD 2 patients and maintenance-naïve patients, tiotropium/olodaterol reduced the risk of CID versus tiotropium. These results demonstrate the advantages of treatment optimisation with tiotropium/olodaterol over tiotropium monotherapy.
