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 beta(2)-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-naive 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 mu g or tiotropium 5 mu g (delivered via Respimat(R)) in two replicate, 52-week, parallel-group, double-blind studies (TONADO(R) 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-naive 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-naive patients, tiotropium/olodaterol reduced the risk of CID versus tiotropium. These results demonstrate the advantages of treatment optimisation with tiotropium/olodaterol over tiotropium monotherapy.

PLAIN LANGUAGE SUMMARY COPD is a complicated disease that deteriorates over time. Worsening of COPD is associated with the lungs working less effectively, a fall in quality of life and a rise in sudden flare-ups of the disease. In this study, we looked at lung function, quality of life and flare-ups together using a measure called "clinically important deterioration" (CID). We looked at 2055 people with COPD to compare the effects of taking two bronchodilators (tiotropium and olodaterol) against taking one bronchodilator (tiotropium alone). Bronchodilators are a type of inhaled medication that relax the muscles in the lungs and widen airways, making it easier to breathe. They have also been shown to reduce sudden flare-ups of COPD. Across a wide range of people with COPD, we found that treatment with tiotropium/olodaterol reduced the risk of a CID compared with tiotropium alone. This includes in those patients at an early stage of disease, who may benefit from finding the best treatment option for them as early as possible.
