Abstract Background: Combinations of long-acting bronchodilators with different mechanisms of action are recommended to improve prognosis and reduce risk of adverse events of chronic obstructive pulmonary disease (COPD). It is unclear whether the new combination therapy with long-acting muscarinic antagonist (LAMA) tiotropium (TIO) and long acting beta-agonists (LABA) olodaterol (OLO) was superior to tiotropium alone. Methods: We measured the efficacy of the TIO/OLO combination vsTIO alone for COPD patients based on electronic databases up to February 2019. After rigorous quality review, data was extracted from eligible trials. All the main outcomes were pooled analysis using RevMan software. Results: A total of 6 randomized controlled trials (RCTs) were identified. The pooled results of our meta-analysis demonstrated that FEV1 [MD = 0.03, 95% CI (−0.01,0.07), P = .18], FVC [MD = -0.03, 95%CI (−0.06,0.00), P = .09] and FEV1%pred [MD = 0.35, 95%CI (−0.30, 0.99), P = .29] all showed no significant difference between the 2 groups. The overall incidence of adverse effects (AEs) [OR = 1.01,95%CI (0.93,1.09), P = .87] and serious AEs [OR = 1.04,95% CI (0.82, 1.32), P = .72] in the combination group was similar to that of the TIO alone group, without statistical significance. Conclusion: These studies reported that the TIO/OLO combination did not show superior effects than tiotropium alone for COPD. Additionally, both therapies were well tolerated.

ObjectivesTo evaluate the effects of tiotropium/olodaterol (T/O) on phase-resolved functional lung (PREFUL) MRI parameters in hyperinflated chronic obstructive pulmonary disease (COPD) patients and examine correlations with conventional cardiopulmonary and hyperpolarized 129Xe MRI measures.Materials and methodsRetrospective subanalysis of a prospective, randomized, placebo-controlled, crossover trial with open-label extension. Thirty-two patients with moderate-to-severe COPD (61.5 ± 7.7 years; 17 men); 30 completed the MRI extension at 1.5 T. PREFUL analysis yielded regional ventilation (RVent), flow-volume loop correlation metric (FVL-CM), normalized perfusion (QN), ventilation defect percentage (VDP), perfusion defect percentage (QDP), V/Q match metrics (VQM), and pulmonary pulse wave velocity (PWV; post-hoc parameter). Linear mixed-effects models tested treatment effects; correlations were evaluated with Spearman's rank and bootstrap 95% confidence intervals (95% CIs).ResultsPREFUL parameters improved after T/O single dose (SD) versus placebo, including improvements in FVL-CM by 4.1 percentage points (pp; 95% CI: 1.0 to 7.3 pp) and QN by 0.4 pp (95% CI: 0.2 to 0.6 pp) and reductions in VDP and QDP, with parallel gains in VQM(Non-Defect) (p 129Xe MRI. SD treatment-induced absolute changes in VDP(FVL-CM) correlated with reductions in residual volume (ρ = 0.41, 95% CI: 0.02 to 0.64). Further correlations were observed between PREFUL MRI and ¹²⁹Xe-derived VDP, apparent diffusion coefficient, and compartment ratios.ConclusionPREFUL MRI sensitively captured immediate SD T/O-induced improvements in V/Q parameters and dose-dependent PWV responses after sustained bronchodilation.Key pointsQuestion Can phase-resolved functional lung (PREFUL) MRI sensitively capture immediate single-dose and sustain multi-dose effects of tiotropium/olodaterol on ventilation-perfusion and vascular function in COPD patients? Findings Tiotropium/olodaterol improved PREFUL MRI-derived ventilation, perfusion, and V/Q matching parameters after a single dose, with sustained pulmonary vascular improvements after repeated dosing. Clinical relevance PREFUL MRI detected immediate and sustained functional improvements after tiotropium/olodaterol and showed significant correlations with cardiopulmonary tests and hyperpolarized ¹²⁹Xe MRI, supporting its role as a sensitive, radiation-free tool for monitoring COPD treatment response.

BackgroundChronic obstructive pulmonary disease (COPD) is one of the most common comorbidities in patients with chronic heart failure (CHF). A growing number of patients are suffering from both COPD and CHF, and these conditions worsen each other. Inhaled bronchodilator therapy with long-acting muscarinic antagonist (LAMA) and long-acting β2-agonist (LABA) in combination is currently the mainstay of treatment for COPD. However, the effect of LAMA/LABA on HF with COPD remains unknown.Methods and resultsThe COPD-HF trial is a multicenter, double-arm, open-label, exploratory, investigator-initiated clinical study to investigate the effect of LAMA/LABA on HF in patients suffering from both COPD and CHF. The participants are randomly assigned (1 : 1) to the LAMA/LABA (tiotropium+olodaterol FDC (fixed-dose combination) 5/5 ug) group (once a day, 2 inhalations) or non-pharmacological treatments for COPD as a control group. The planned number of patients to be enrolled in this trial is 54 in total (27 in each group). The participants are followed up for 12 weeks with and without LAMA/LABA. The primary endpoint is the change in plasma B-type natriuretic peptide levels from the baseline to the end of this study (12 weeks).ConclusionsThe COPD-HF trial will investigate the efficacy of LAMA/LABA on HF in patients with COPD and CHF.

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 β2-agonists (LABAs) or inhaled corticosteroids (ICS) (“maintenance naïve”) at study entry. 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 (FEV1) < 80% predicted (lower limit FEV1 ≥ 30% in OTEMTO 1/2 only). We examined the effect of tiotropium/olodaterol 5/5 µg versus tiotropium 5 µg on trough FEV1 response, St. George’s Respiratory Questionnaire (SGRQ) total score and Transition Dyspnoea Index (TDI) focal score at 12 weeks in four pooled studies. The pooled analysis included 1078 maintenance-naïve patients. There were significant improvements with tiotropium/olodaterol versus tiotropium in trough FEV1 [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 (FEV1 ≥ 0.1 L, SGRQ ≥ 4.0 points or TDI ≥ 1.0 point) were higher versus tiotropium. 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. ClinicalTrials.gov: TONADO® 1 and 2 (NCT01431274 and NCT01431287, registered 8 September 2011) and OTEMTO® 1 and 2 (NCT01964352 and NCT02006732, registered 14 October 2013). People with chronic obstructive pulmonary disease (COPD) often have problems breathing, which can make it difficult to carry out daily physical tasks. Bronchodilators are a type of medication that relax the muscles in the lungs and widen airways, making it easier to breathe. Evidence suggests that using a combination of two different bronchodilators is more effective than using one bronchodilator on its own. In this article, we look at four large studies that compared the effects of at least 12 weeks of treatment with two bronchodilators (tiotropium/olodaterol) with tiotropium on its own in people who had not received any previous medication for their COPD. The results suggest that people who were treated with tiotropium and olodaterol together had significantly better improvements in lung function, quality of life and breathlessness after 12 weeks than those taking tiotropium alone, without compromising safety. Overall, people treated with tiotropium/olodaterol were 60% more likely to experience a meaningful improvement in at least one of these areas compared with those on tiotropium alone. These results support the use of tiotropium and olodaterol together as a first medication for COPD.

IntroductionDuring the clinical development of a fixed-dose combination of drugs, it is best practice to conduct dose-finding studies to determine the optimal dose of each component. The aims of this phase II dose-finding study were to confirm the lung function benefit of adding olodaterol to tiotropium, describe the dose–response relationship of olodaterol in combination with tiotropium 5 μg, and compare it with the dose response of olodaterol monotherapy.MethodsIn this double-blind, parallel-group trial, patients were randomized to receive either tiotropium 5 μg or a fixed-dose combination of tiotropium 5 μg with olodaterol 2 μg, 5 μg, or 10 μg, delivered once daily via the Respimat® for 4 weeks (NCT00696020). Patients had a diagnosis of chronic obstructive pulmonary disease and post-bronchodilator forced expiratory volume in 1 s (FEV1) ≥ 30 and < 80% of predicted normal. The primary endpoint was trough FEV1 response (change from baseline) after 4 weeks. Secondary endpoints included FEV1 and forced vital capacity (FVC) over 6 h after dosing.ResultsCompared with tiotropium 5 μg, mean (standard error) trough FEV1 increased with the addition of olodaterol 2 μg by 0.024 L (0.027), olodaterol 5 μg by 0.033 L (0.027), and olodaterol 10 μg by 0.057 L (0.027). Statistically significant improvements in FEV1 versus tiotropium were seen across all timepoints up to 6 h with all doses of tiotropium/olodaterol. Similar results were observed for FVC.ConclusionThere was a benefit of tiotropium/olodaterol compared with tiotropium monotherapy in FEV1 and FVC. There was a dose–response relationship for olodaterol on top of tiotropium for FEV1 and FVC similar to the dose response previously seen for olodaterol monotherapy. These results, together with the results of a study investigating the dose response of tiotropium on top of olodaterol, helped to inform the dose selection for the phase III studies.FundingBoehringer Ingelheim International GmbH.
