Profile of a fixed-dose combination of tiotropium/olodaterol and its potential in the treatment of COPD.

ABSTRACT: Chronic obstructive pulmonary disease (COPD) is a progressive, debilitating disorder that results in frequent exacerbations and impacts quality of life. It represents a growing burden of health care cost, both from societal and economic perspectives. Short- and long-acting bronchodilators remain the mainstay of therapy in COPD patients. New fixed-dose combination inhalers with novel pharmacological combinations of long-acting ?2-agonists and muscarinic antagonists and delivered once-daily through a variety of devices are currently being developed and licensed for the treatment of COPD. There is mounting research suggesting that combining a fixed dose of a ?2-agonist and a muscarinic antagonist achieves better bronchodilation and clinical outcomes compared with either agent alone. These once-daily dosing inhalers are anticipated to impact favorably on patient preference and compliance. This review examines the fixed-dose combination of tiotropium bromide and olodaterol delivered by a Respimat(®) Soft Mist™ inhaler at doses of 2.5/5 ?g and 5/5 ?g in moderate-to-very-severe COPD, and its potential role in COPD compared with other long-acting ?2-agonist with long-acting muscarinic antagonist combinations and delivery devices.

Project description: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.

Project description:ObjectivesChronic obstructive pulmonary disease (COPD) guidelines advocate treatment with combinations of long-acting bronchodilators for patients with COPD who have persistent symptoms or continue to have exacerbations while using a single bronchodilator. This study assessed the cost-utility of the fixed dose combination of the bronchodilators tiotropium and olodaterol versus two comparators, tiotropium monotherapy and long-acting β2 agonist/inhaled corticosteroid (LABA/ICS) combinations, in three European countries: Finland, Sweden and the Netherlands.MethodsA previously published COPD patient-level discrete event simulation model was updated with most recent evidence to estimate lifetime quality-adjusted life years (QALYs) and costs for COPD patients receiving either tiotropium/olodaterol, tiotropium monotherapy or LABA/ICS. Treatment efficacy covered impact on trough forced expiratory volume in 1 s (FEV1), total and severe exacerbations and pneumonias. The unit costs of medication, maintenance treatment, exacerbations and pneumonias were obtained for each country. The country-specific analyses adhered to the Finnish, Swedish and Dutch pharmacoeconomic guidelines, respectively.ResultsTreatment with tiotropium/olodaterol gained QALYs ranging from 0.09 (Finland and Sweden) to 0.11 (the Netherlands) versus tiotropium and 0.23 (Finland and Sweden) to 0.28 (the Netherlands) versus LABA/ICS. The Finnish payer's incremental cost-effectiveness ratio (ICER) of tiotropium/olodaterol was €11 000/QALY versus tiotropium and dominant versus LABA/ICS. The Swedish ICERs were €6200/QALY and dominant, respectively (societal perspective). The Dutch ICERs were €14 400 and €9200, respectively (societal perspective). The probability that tiotropium/olodaterol was cost-effective compared with tiotropium at the country-specific (unofficial) threshold values for the maximum willingness to pay for a QALY was 84% for Finland, 98% for Sweden and 99% for the Netherlands. Compared with LABA/ICS, this probability was 100% for all three countries.ConclusionsBased on the simulations, tiotropium/olodaterol is a cost-effective treatment option versus tiotropium or LABA/ICS in all three countries. In both Finland and Sweden, tiotropium/olodaterol is more effective and cost saving (ie, dominant) in comparison with LABA/ICS.

Project description:BackgroundEscalation to triple therapy (long-acting muscarinic antagonist/β2-agonist, inhaled corticosteroid [ICS]) in chronic obstructive pulmonary disorder (COPD) is recommended for patients on LAMA/LABA combinations with frequent exacerbations and severe symptoms. An extended time-to-escalation to triple therapy suggests patients are in a stable condition and is an indicator of treatment effectiveness. No studies in Japanese clinical practice have compared the effectiveness of LAMA/LABA fixed-dose combination therapies with LAMA monotherapy in terms of time-to-escalation to triple therapy. The primary objective of this real-world study in Japan was to compare time-to-escalation to triple therapy among new users of tiotropium/olodaterol or tiotropium monotherapy for COPD without asthma.MethodsIn this active-comparator cohort study, new users of tiotropium/olodaterol (n = 1436) and tiotropium monotherapy (n = 5352) were identified from a large Japanese hospital-based database (Medical Data Vision Co., Ltd., Tokyo; prespecified study period: 1 April 2015 to 31 March 2019); patients in each group were matched 1:1 using high-dimensional propensity scores (hdPS). The primary outcome was time-to-escalation to triple therapy.ResultsFor the prespecified study period in the hdPS-matched cohort, escalation to triple therapy was infrequent among new users of tiotropium/olodaterol (n = 1302, 7 escalation events) and tiotropium monotherapy (n = 1302, 8 escalation events). The difference in time-to-escalation to triple therapy between groups was not statistically significant (median [interquartile range]: 28 days [15.0-139.2] for tiotropium monotherapy vs 193 days [94.5-302.0] for tiotropium/olodaterol; hazard ratio: 0.89; 95% CI: 0.32-2.46). Similar findings (hazard ratio: 0.71; 95% Cl: 0.36-1.40) were observed in a post hoc analysis, which extended the study period by 1 year to 31 March 2020. Risks of first moderate and/or severe COPD exacerbation were lower for tiotropium/olodaterol than tiotropium monotherapy (between-group differences not significant). There were no significant between-group differences for the risks of all-cause inpatient mortality, major adverse cardiovascular events, and first use of home oxygen therapy.ConclusionsICS monotherapy or ICS/LABA added to tiotropium or tiotropium/olodaterol is limited in Japanese clinical settings. The number of escalations to triple therapy was very limited in the dataset and there was insufficient power to detect differences between the treatment groups in the primary hdPS-matched cohort.
