Cost-effectiveness analysis of a fixed-dose combination of indacaterol and glycopyrronium as maintenance treatment for COPD.

ABSTRACT: The aim of this study was to evaluate the cost-effectiveness of the long-acting beta-2 agonist (LABA)/long-acting muscarinic antagonist (LAMA) dual bronchodilator indacaterol/glycopyrronium (IND/GLY) as a maintenance treatment for COPD patients from the perspective of health care payer in Taiwan.We adopted a patient-level simulation model, which included a cohort of COPD patients aged ?40 years. The intervention used in the study was the treatment using IND/GLY, and comparators were tiotropium or salmeterol/fluticasone combination (SFC). Data related to the efficacy of drugs, incidence of exacerbation, and utility were obtained from clinical studies. Direct costs were estimated from claims data based on the severity of COPD. The cycle length was 6 months (to match forced expiratory volume in 1 second [FEV1] data), and the time horizons included 1, 3, 5, 10 years, and lifetime. Deterministic and probabilistic sensitivity analyses were conducted to test the robustness of the model results. Costs were expressed in US dollars with a discount rate of 3.0%.Compared to tiotropium and SFC, the incremental cost-effectiveness ratios (ICERs) per quality-adjusted life year (QALY) gained of patients treated with IND/GLY were US$5,987 and US$14,990, respectively. One-way sensitivity analysis revealed that the improvement in FEV1 provided by IND/GLY, the distribution of patients with regard to the severity of COPD, and acute exacerbation rate ratio were the key drivers behind cost-effectiveness. Adopting a willingness to pay of US$60,000 per QALY gained as the threshold, there was a 98.7% probability that IND/GLY was cost-effective compared to tiotropium. Similarly, there was a 99.9% probability that IND/GLY was cost-effective compared to SFC.As a maintenance treatment for COPD, we consider the dual bronchodilator IND/GLY as a cost-effective strategy when compared to either tiotropium or SFC.

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:BackgroundLABA (long-acting β2-agonists) and/or LAMA (long-acting muscarinic antagonists) represent the first treatment options for patients with symptomatic COPD. Although both display different mechanisms of activity, in combination they have a stronger broncho-dilating effect than monotherapy; hence, a combination of both LABA and LAMA is particularly recommended for patients whose symptoms cannot be sufficiently improved by a single active ingredient. To date, only few data have been collected regarding the therapeutic outcomes of approved LABA/LAMA fixed-dose combinations (FDCs) under everyday (real-life) conditions in non-clinical trial settings.Objective and methodsThe main objective of the DETECT study was to investigate the impact of aclidinium/formoterol (AB/FF, b.i.d.), glycopyrronium/indacaterol (GLY/IND, q.d.) and umeclidinium/vilanterol (UME/VL, q.d.) in patients with COPD in daily clinical practice. Therefore, a prospective, non-randomized, 12-month, observational study was implemented to assess the effectiveness of these treatments in patients who had been switched to FDC within the last 3 months or for whom such a changeover was intended. Changes in lung function were analyzed by the forced expiratory volume (FEV1) and forced vital capacity (FVC) measures. Quality of life and well-being were evaluated by the COPD Assessment Test (CAT™). Furthermore, a number of exacerbations and early morning COPD symptoms were documented.ResultsIn total, 3653 patients were enrolled. FEV1 and FVC values significantly improved during the study with AB/FF (increase by 0.09 ± 0.40 L and 0.10 ± 0.57 L, respectively; p<0.0001), GLY/IND (0.06±0.38/0.05±0.51 L; p<0.0001 and p=0.0025) and UME/VL (0.12±0.39/0.10±0.52 L; p<0.0001). CAT scores decreased indicating improved COPD (AB/FF, 4.17±8.30; GLY/IND, 3.66±7.88; UME/VL, 4.06±7.96; p<0.0001). Moreover, the number of exacerbations as well as early morning COPD symptoms similarly diminished in all treatment groups. A comparable proportion of patients with adverse drug reactions was recorded: AB/FF, 4.07% of patients; GLY/IND, 3.52%; UME/VL, 3.64%.ConclusionIn summary, AB/FF, GLY/IND and UME/VL provided clinical benefits in lung function, quality of life and early morning COPD symptoms in a broad cohort of COPD patients under routine medical practice conditions. All three treatments were well tolerated.

Project description:The objective of the FAVOR study was to evaluate the effect of indacaterol/glycopyrronium (IND/GLY) versus tiotropium on peak forced expiratory volume in 1 s (FEV1) and also to investigate patient satisfaction and treatment preference.Patients with moderate-to-severe airflow limitation (FEV1/forced vital capacity ratio of <0.70), those with a COPD assessment test score of ?10, and those who were maintained on tiotropium HandiHaler® therapy prior to enrollment were recruited for the study, and randomized (1:1) to receive either 4 weeks open-label IND/GLY (110/50 ?g) once daily followed by 4 weeks of tiotropium (18 ?g) once daily or vice versa. The primary endpoint was FEV1 1 h post-inhalation after 4 weeks of treatment. Other endpoints included patient's and physician's preference for treatment, patient's satisfaction evaluated using a study-specific questionnaire and the abbreviated Treatment Satisfaction Questionnaire for Medication, and safety and tolerability.Eighty-seven out of 88 randomized patients completed the study and showed significantly higher FEV1 1 h post-inhalation after 4 weeks of treatment with IND/GLY versus tiotropium (treatment difference =0.081 L; p=0.0017). IND/GLY was preferred over tiotropium among the patients (69.4% versus 30.6%, p=0.0004) and the physicians (81.6% versus 18.4%, p<0.0001). A higher proportion of the patients stated they were very satisfied or satisfied with IND/GLY versus tiotropium with regard to dyspnea reduction (79.3% versus 58.0%, respectively) and reduction of dyspnea on exertion (72.4% versus 43.2%, respectively). Patients treated with IND/GLY showed significant improvement in Treatment Satisfaction Questionnaire for Medication domain scores versus tiotropium. IND/GLY demonstrated a good safety and tolerability profile.This study indicated that, beyond FEV1, important patient-reported outcomes improved with the open-label dual bronchodilator IND/GLY when compared with tiotropium. This study suggests that individual patients felt the lung function benefits with IND/GLY compared with tiotropium, which, in turn, may also have contributed to the preference for IND/GLY.
