RESUMEN
BACKGROUND: Cost-effectiveness of once-daily umeclidinium bromide (UMEC) was compared with once-daily tiotropium (TIO) and once-daily glycopyrronium (GLY) in patients with chronic obstructive pulmonary disease (COPD) from a UK National Health Service (NHS) perspective. METHODS: A linked-equation model was implemented to estimate COPD progression, associated healthcare costs, exacerbations rates, life years (LY) and quality-adjusted LY (QALYs). Statistical risk equations for endpoints and resource use were derived from the ECLIPSE and TORCH studies, respectively. Treatment effects [mean (standard error)] at 12 weeks on forced expiratory volume in 1 s and St George's Respiratory Questionnaire score were obtained from the intention-to-treat populations of two head-to-head studies [GSK study identifiers 201316 (NCT02207829) and 201315 (NCT02236611)] which compared UMEC 62.5 mcg with TIO 18 mcg and UMEC 62.5 mcg with GLY 50 mcg, respectively. Treatment costs reflect UK list prices (2016) and NHS unit costs; UMEC and GLY prices being equal and less than TIO. A lifetime horizon, discounted costs and effects at 3.5% were used. Sensitivity analyses were performed to evaluate the robustness of variations in input parameters and assumptions in the model. RESULTS: Over a lifetime horizon, UMEC was predicted to increase LYs (+ 0.195; 95% confidence interval [CI]: 0.069, 0.356) and QALYs (+ 0.118; 95% CI: 0.055, 0.191) and reduce the number of annual exacerbations (- 0.053; 95% CI: - 0.171, 0.028) compared with TIO, with incremental cost savings of £460/patient (95% CI: - £645, - £240). Compared with GLY, UMEC increased LYs (+ 0.124; 95% CI: 0.015, 0.281) and QALYs (+ 0.101; 95% CI: 0.043, 0.179) and reduced annual exacerbation (- 0.033; 95% CI: - 0.135, 0.017) at an additional cost of £132/patient (95% CI: £12, £330), resulting in an incremental cost-effectiveness ratio of £1310/QALY (95% CI: £284, £2060). Similar results were observed in alternative time horizons and additional sensitivity analyses. CONCLUSIONS: For treatment of patients with COPD in the UK over a lifetime horizon, treatment with UMEC dominates treatment with TIO, providing both improved health outcomes and cost savings. In comparison with GLY, treatment with UMEC achieved improved health outcomes but was associated with a higher cost.Trial registration 201316, NCT02207829; 201315, NCT02236611.
RESUMEN
OBJECTIVES: To validate outcomes of presently available chronic obstructive pulmonary disease (COPD) cost-effectiveness models against results of two large COPD trials-the 3-year TOwards a Revolution in COPD Health (TORCH) trial and the 4-year Understanding Potential Long-term Impacts on Function with Tiotropium (UPLIFT) trial. METHODS: Participating COPD modeling groups simulated the outcomes for the placebo-treated groups of the TORCH and UPLIFT trials using baseline characteristics of the trial populations as input. Groups then simulated treatment effectiveness by using relative reductions in annual decline in lung function and exacerbation frequency observed in the most intensively treated group compared with placebo as input for the models. Main outcomes were (change in) total/severe exacerbations and mortality. Furthermore, the absolute differences in total exacerbations and quality-adjusted life-years (QALYs) were used to approximate the cost per exacerbation avoided and the cost per QALY gained. RESULT: Of the six participating models, three models reported higher total exacerbation rates than observed in the TORCH trial (1.13/patient-year) (models: 1.22-1.48). Four models reported higher rates than observed in the UPLIFT trial (0.85/patient-year) (models: 1.13-1.52). Two models reported higher mortality rates than in the TORCH trial (15.2%) (models: 20.0% and 30.6%) and the UPLIFT trial (16.3%) (models: 24.8% and 36.0%), whereas one model reported lower rates (9.8% and 12.1%, respectively). Simulation of treatment effectiveness showed that the absolute reduction in total exacerbations, the gain in QALYs, and the cost-effectiveness ratios did not differ from the trials, except for one model. CONCLUSIONS: Although most of the participating COPD cost-effectiveness models reported higher total exacerbation rates than observed in the trials, estimates of the absolute treatment effect and cost-effectiveness ratios do not seem different from the trials in most models.

OBJECTIVES: To assess how suitable current chronic obstructive pulmonary disease (COPD) cost-effectiveness models are to evaluate personalized treatment options for COPD by exploring the type of heterogeneity included in current models and by validating outcomes for subgroups of patients. METHODS: A consortium of COPD modeling groups completed three tasks. First, they reported all patient characteristics included in the model and provided the level of detail in which the input parameters were specified. Second, groups simulated disease progression, mortality, quality-adjusted life-years (QALYs), and costs for hypothetical subgroups of patients that differed in terms of sex, age, smoking status, and lung function (forced expiratory volume in 1 second [FEV1] % predicted). Finally, model outcomes for exacerbations and mortality for subgroups of patients were validated against published subgroup results of two large COPD trials. RESULTS: Nine COPD modeling groups participated. Most models included sex (seven), age (nine), smoking status (six), and FEV1% predicted (nine), mainly to specify disease progression and mortality. Trial results showed higher exacerbation rates for women (found in one model), higher mortality rates for men (two models), lower mortality for younger patients (four models), and higher exacerbation and mortality rates in patients with severe COPD (four models). CONCLUSIONS: Most currently available COPD cost-effectiveness models are able to evaluate the cost-effectiveness of personalized treatment on the basis of sex, age, smoking, and FEV1% predicted. Treatment in COPD is, however, more likely to be personalized on the basis of clinical parameters. Two models include several clinical patient characteristics and are therefore most suitable to evaluate personalized treatment, although some important clinical parameters are still missing.

BACKGROUND: This cost-utility analysis assessed the long-term clinical and economic benefits of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) triple therapy vs FF/VI or UMEC/VI from a Quebec societal perspective in patients with chronic obstructive pulmonary disease (COPD) with ≥1 moderate/severe exacerbation in the previous year. METHODS: The validated GALAXY disease progression model was utilized, with parameters set to baseline and efficacy data from IMPACT. Treatment costs (2017 Canadian dollars [C$]) were estimated using Quebec-specific unit costs. Costs and health outcomes were discounted at 1.5 %/year. A willingness-to-pay threshold of C$50,000/quality-adjusted life year (QALY) was considered cost-effective. Outcomes modeled were exacerbation rates, QALYs, life years (LYs), costs and incremental cost-effectiveness ratios (ICERs). Subgroup analyses were performed according to prior treatment, exacerbation history in the previous year, and baseline lung function. RESULTS: Over a lifetime horizon, FF/UMEC/VI resulted in more QALYs and LYs gained, at a small incremental cost compared with FF/VI and UMEC/VI. From a societal perspective, the estimated ICER for the base case was C$18,152/QALY vs FF/VI, and C$15,847/QALY vs UMEC/VI. For the subgroup analyses (FF/UMEC/VI compared with FF/VI and UMEC/VI), ICERs ranged from: C$17,412-25,664/QALY and C$16,493-18,663/QALY (prior treatment); C$15,247-19,924/QALY and C$15,444-28,859/QALY (exacerbation history); C$14,025-34,154/QALY and C$16,083-17,509/QALY (baseline lung function). INTERPRETATION: FF/UMEC/VI was predicted to improve outcomes and be cost-effective vs both comparators in the base case and all subgroup analyses, and based on this analysis would be an appropriate investment of health service funds in Quebec. CLINICAL TRIAL REGISTRATION NUMBER: IMPACT trial NCT02164513.

BACKGROUND: The IMPACT trial demonstrated superior outcomes following 52â weeks of once-daily single-inhaler treatment with fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI) (100/62.5/25â µg) compared with once-daily FF/VI (100/25â µg) or UMEC/VI (62.5/25â µg). This study evaluated the cost-effectiveness of FF/UMEC/VI compared with FF/VI or UMEC/VI for the treatment of chronic obstructive pulmonary disease (COPD) from a UK National Health Service perspective. METHODS: Patient characteristics and treatment effects from IMPACT were populated into a hybrid decision tree/Markov economic model. Costs (GB£ inflated to 2018 equivalents) and health outcomes were modelled over a lifetime horizon, with a discount rate of 3.5% per annum applied to both. Sensitivity analyses were performed to test the robustness of key assumptions and input parameters. RESULTS: Compared with FF/VI and UMEC/VI, FF/UMEC/VI provided an additional 0.296 and 0.145 life years (LYs) (discounted) and 0.275 and 0.118 quality-adjusted life years (QALYs), at an additional cost of £1129 and £760, respectively. Incremental cost-effectiveness ratios (ICERs) for FF/UMEC/VI were £4104/QALY and £3809/LY gained versus FF/VI and £6418/QALY and £5225/LY gained versus UMEC/VI. At a willingness-to-pay threshold of £20â000/QALY, the probability that FF/UMEC/VI was cost-effective was 96% versus FF/VI and 74% versus UMEC/VI. Results were similar in a subgroup of patients recommended triple therapy in the 2019 National Institute for Health and Care Excellence COPD guideline. CONCLUSIONS: FF/UMEC/VI single-inhaler triple therapy improved health outcomes and was a cost-effective option compared with FF/VI or UMEC/VI for patients with symptomatic COPD and a history of exacerbations in the UK at recognised cost-effectiveness threshold levels.
RESUMEN
Purpose: The 24-week INTREPID trial demonstrated the clinical benefits of once-daily single-inhaler triple therapy (SITT) with fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI) versus non-ELLIPTA multiple-inhaler triple therapy (MITT) in patients with symptomatic chronic obstructive pulmonary disease (COPD). This analysis assessed the cost-effectiveness of FF/UMEC/VI versus non-ELLIPTA MITT for the treatment of symptomatic COPD from a United Kingdom (UK) National Health Service (NHS) perspective. Patients and Methods: The analysis was conducted using the validated GALAXY COPD disease progression model. Baseline characteristics, treatment effect parameters (forced expiratory volume in 1 second and St. George's Respiratory Questionnaire score [derived from exploratory COPD Assessment Test score mapping]), and discontinuation data from INTREPID were used to populate the model. UK healthcare resource and drug costs (2020 British pounds) were applied, and costs and outcomes were discounted at 3.5%. Analyses were conducted over a lifetime horizon from a UK NHS perspective. Model outputs included exacerbation rates, total costs, life years (LYs), quality-adjusted LYs (QALYs) and incremental cost-effectiveness ratio per QALY. Sensitivity analyses were conducted to assess the robustness of the results by varying parameter values and assumptions. Results: Over a lifetime horizon, FF/UMEC/VI provided an additional 0.174 (95% confidence interval [CI]: 0.024, 0.344) LYs (approximately 2 months), and 0.253 (95% CI: 0.167, 0.346) QALYs (approximately 3 months), at a cost saving of £1764 (95% CI: -£2600, -£678) per patient, compared with non-ELLIPTA MITT. FF/UMEC/VI remained the dominant treatment option, meaning greater benefits at lower costs, across all scenario and sensitivity analyses. Conclusion: Based on this analysis, in a UK setting, FF/UMEC/VI would improve health outcomes and reduce costs compared with non-ELLIPTA MITT for the treatment of patients with symptomatic COPD. SITT may help to reduce the clinical and economic burden of COPD and should be considered by physicians as a preferred treatment option.

INTRODUCTION: Randomized controlled trials (RCTs) comparing triple therapies (inhaled corticosteroid [ICS], long-acting ß2-agonist [LABA], and long-acting muscarinic antagonist [LAMA]) for the treatment of chronic obstructive pulmonary disease (COPD) are limited. This network meta-analysis (NMA) investigated the comparative efficacy of single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus any triple (ICS/LABA/LAMA) combinations and dual therapies in patients with COPD. METHODS: This NMA was conducted on the basis of a systematic literature review (SLR), which identified RCTs in adults aged at least 40 years with COPD. The RCTs compared different ICS/LABA/LAMA combinations or an ICS/LABA/LAMA combination with any dual therapy (ICS/LABA or LAMA/LABA). Outcomes of interest included forced expiratory volume in 1 s (FEV1), annualized rate of combined moderate and severe exacerbations, St George's Respiratory Questionnaire (SGRQ) total score and SGRQ responders, transition dyspnea index focal score, and rescue medication use (RMU). Analyses were conducted at 24 weeks (primary endpoint), and 12 and 52 weeks (if feasible). RESULTS: The NMA was informed by five trials reporting FEV1 at 24 weeks. FF/UMEC/VI was statistically significantly more effective at increasing trough FEV1 (based on change from baseline) than all triple comparators in the network apart from UMEC + FF/VI. The NMA was informed by 17 trials reporting moderate or severe exacerbation endpoints. FF/UMEC/VI demonstrated statistically significant improvements in annualized rate of combined moderate or severe exacerbations versus single-inhaler budesonide/glycopyrronium bromide/formoterol fumarate (BUD/GLY/FOR). At 24 weeks, the NMA was informed by five trials. FF/UMEC/VI showed statistically significant improvements in annualized rate of combined moderate or severe exacerbations versus UMEC + FF/VI and BUD/GLY/FOR. FF/UMEC/VI also demonstrated improvements in mean SGRQ score versus other triple therapy comparators at 24 weeks, and a significant reduction in RMU compared with BUD/GLY/FOR (160/18/9.6). CONCLUSION: The findings of this NMA suggest favorable efficacy with single-inhaler triple therapy comprising FF/UMEC/VI. Further analysis is required as additional evidence becomes available.

Objectives: In the IMPACT trial (NCT02164513), triple therapy with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) showed clinical benefit compared with dual therapy with either FF/VI or UMEC/VI in the treatment of chronic obstructive pulmonary disease (COPD). We used data from IMPACT to determine whether this translated into differences in COPD-related healthcare resource utilization (HRU) costs in a United Kingdom (UK) setting. Methods: In a within-trial analysis, individual patient data from the IMPACT intention-to-treat (ITT) population were analyzed to estimate rates of COPD-related HRU with FF/UMEC/VI, FF/VI, or UMEC/VI. A Bayesian approach was applied to address issues typically encountered with this kind of data, namely data missing due to early study withdrawal, subjects with zero reported HRU, and skewness. Rates of HRU were estimated under alternate assumptions of data being missing at random (MAR) or missing not at random (MNAR). UK-specific unit costs were then applied to estimated HRU rates to calculate treatment-specific costs. Results: Under each MNAR scenario, per patient per year (PPPY) rates of COPD-related HRU were lowest amongst those patients who received treatment with FF/UMEC/VI compared with those receiving either FF/VI or UMEC/VI. Although absolute HRU rates and costs were typically higher for all treatment groups under MNAR scenarios versus MAR, final economic conclusions were robust to patient withdrawals. Conclusions: PPPY rates were typically lower with FF/UMEC/VI versus FF/VI or UMEC/VI.

UK management costs for COPD, estimated at £1.9â billion/year, are rising. In the FULFIL (Lung Function and Quality of Life Assessment in Chronic Obstructive Pulmonary Disease with Closed Triple Therapy) study, single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol (100/62.5/25â µg) improved clinical outcomes versus budesonide/formoterol (400/12â µg) in patients with symptomatic COPD at risk of exacerbations. We assessed the cost-effectiveness of fluticasone furoate/umeclidinium/vilanterol versus budesonide/formoterol for treating COPD from a UK National Health Service perspective. A model was developed combining a trial-based and Markov component and populated with baseline and treatment effect data from FULFIL, together with UK healthcare resource costs and disease-related utilities. Costs per life year and per quality-adjusted life year gained (costing year 2017) for fluticasone furoate/umeclidinium/vilanterol versus budesonide/formoterol were calculated for a lifetime horizon. Results were explored using deterministic sensitivity, scenario and probabilistic analyses. Fluticasone furoate/umeclidinium/vilanterol was associated with gains in life years (0.533) and quality-adjusted life years (0.506) versus budesonide/formoterol, but at slightly increased total costs (£26â416 versus £25â860). This translated to incremental cost-effectiveness ratios of £1042/life year and £1098/quality-adjusted life year for fluticasone furoate/umeclidinium/vilanterol versus budesonide/formoterol. In scenario analyses, incremental cost-effectiveness ratios ranged from dominant to £1547/quality-adjusted life year gained. Fluticasone furoate/umeclidinium/vilanterol provides a cost-effective treatment option versus budesonide/formoterol for patients with symptomatic COPD in the UK.
RESUMEN
PURPOSE: To estimate the incremental cost-utility ratio of oral semaglutide (14 mg once daily) vs other glucagon-like peptide 1 receptor agonist treatments among adults with type 2 diabetes that was inadequately controlled with 1 to 2 oral antidiabetic drugs from a US payer perspective. METHODS: A state-transition model with a competing risk approach was developed for diabetic complications and risk of cardiovascular events based on the UK Prospective Diabetes Study Outcomes Model 1 equations. Baseline population characteristics reflect the PIONEER 4 trial (Efficacy and Safety of Oral Semaglutide Versus Liraglutide and Versus Placebo in Subjects With Type 2 Diabetes Mellitus) of oral semaglutide. Model comparators included subcutaneous semaglutide, dulaglutide, and liraglutide. Treatment effects (change in glycosylated hemoglobin, weight, and systolic blood pressure) were estimated by network meta-analysis. Drug, management, and event costs (in 2019 US dollars), survival after nonfatal events, and utilities were obtained from the literature. Costs and quality-adjusted life-year (QALY) outcomes were discounted at 3% annually over a lifetime horizon. Probabilistic and 1-way sensitivity analyses were performed. FINDINGS: Total estimated costs and QALYs were $144,065 and 12.98 for oral semaglutide, $145,721 and 12.96 for dulaglutide, $145,833 and 12.99 for SC semaglutide, and $149,428 and 12.97 for liraglutide, respectively. Oral semaglutide was less costly and more effective than dulaglutide and liraglutide but less costly than subcutaneous semaglutide with similar effectiveness. Oral semaglutide was favored versus subcutaneous semaglutide in 52.10% of model replications at a willingness-to-pay of $150,000 per QALY. IMPLICATIONS: Oral semaglutide is predicted to offer health benefits similar to subcutaneous semaglutide and ahead of dulaglutide and liraglutide. Oral semaglutide is a cost-effective glucagon-like peptide 1 receptor agonist treatment option.

We conducted an analysis of indirect costs alongside the LY.12 randomized trial in patients with relapsed or refractory (R/R) aggressive non-Hodgkin lymphoma (NHL). Lost productivity data for Canadian patients and caregivers in the trial were collected at baseline and with each chemotherapy cycle pre-transplant, using an adapted Lost Productivity questionnaire. Mean per patient indirect costs were CAD 2999 for patients in the GDP arm and CAD 3400 in the DHAP arm. A substantial majority was not working or had to reduce their workload during this treatment time. Salvage chemotherapy for R/R aggressive NHL is associated with significant indirect costs to patients and their caregivers.

INTRODUCTION: Dual bronchodilators are recommended as maintenance treatment for patients with symptomatic COPD in the UK; further evidence is needed to evaluate cost-effectiveness versus monotherapy. Cost-effectiveness of umeclidinium/vilanterol versus umeclidinium and salmeterol from a UK healthcare perspective in patients without exacerbations in the previous year was assessed using post hoc EMAX trial data. METHODS: The validated GALAXY model was populated with baseline characteristics and treatment effects from the non-exacerbating subgroup of the symptomatic EMAX population (COPD assessment test score ≥10) and 2020 UK healthcare and drug costs. Outputs included estimated exacerbation rates, costs, life-years (LYs), and quality-adjusted LYs (QALYs); incremental cost-effectiveness ratio (ICER) was calculated as incremental cost/QALY gained. The base case (probabilistic model) used a 10-year time horizon, assumed no treatment discontinuation, and discounted future costs and QALYs by 3.5% annually. Sensitivity and scenario analyses assessed robustness of model results. RESULTS: Umeclidinium/vilanterol treatment was dominant versus umeclidinium and salmeterol, providing an additional 0.090 LYs (95% range: 0.035, 0.158) and 0.055 QALYs (-0.059, 0.168) with total cost savings of £690 (£231, £1306) versus umeclidinium, and 0.174 LYs (0.076, 0.286) and 0.204 QALYs (0.079, 0.326) with savings of £1336 (£1006, £2032) versus salmeterol. In scenario and sensitivity analyses, umeclidinium/vilanterol was dominant versus umeclidinium except over a 5-year time horizon (more QALYs at higher total cost; ICER=£4/QALY gained) and at the lowest estimate of the St George's Respiratory Questionnaire treatment effect (fewer QALYs at lower total cost; ICER=£12,284/QALY gained); umeclidinium/vilanterol was consistently dominant versus salmeterol. At willingness-to-pay threshold of £20,000/QALY, probability that umeclidinium/vilanterol was cost-effective in this non-exacerbating subgroup was 95% versus umeclidinium and 100% versus salmeterol. CONCLUSION: Based on model predictions from a UK perspective, symptomatic patients with COPD and no exacerbations in the prior year receiving umeclidinium/vilanterol are expected to have better outcomes at lower costs versus umeclidinium and salmeterol.

OBJECTIVE: To assess the cost-utility of celecoxib in three treatment strategies for arthritis in Quebec, considering both upper gastrointestinal (GI) and cardiovascular (CV) events. METHODS: A Markov analytic framework was used to model patients with osteoarthritis and rheumatoid arthritis at low/average and high risk of GI and CV toxicity over 5 years with monthly cycles. Treatment strategies were modelled in line with Canadian clinical practice. In first-line treatment, patients started on celecoxib; second-line, patients started on a non-selective non-steroidal anti-inflammatory drug (NSAID) and switched to celecoxib after a first GI event; third-line, patients started on a non-selective NSAID, added a proton pump inhibitor (PPI) after a first GI event, and switched to celecoxib after a second GI event (while maintaining the PPI). Model inputs were determined through comprehensive literature searches (MEDLINE and EMBASE) from 1995 to 2006. Included studies evaluated GI (dyspepsia, uncomplicated and complicated ulcers, death) and CV (myocardial infarction, stroke, death) events. Drug and procedure costs were derived from Canadian published sources (Can$2005). RESULTS: Total costs per patient for celecoxib first-, second-, and third-line treatment were Can$4,790, $3,390, and $3,466, and total quality-adjusted life-years (QALY) were 3.251, 3.231, and 3.230, respectively. In all risk categories, celecoxib second-line was less costly and as effective as celecoxib third-line, producing savings to the healthcare system. Although celecoxib first-line generated incremental expenditures versus celecoxib second-line, it was also more effective. The resulting cost-utility ratio for the high-risk population was Can$54,696/QALY. Based on this analytical approach, a treatment strategy where celecoxib is used before the combination of a non-selective NSAID plus a PPI possesses cost advantages for the Quebec provincial drug programme. One-way sensitivity analysis (varying GI and CV event rates, utilities, and cost) generally showed second-line treatment with celecoxib as the dominant strategy compared with third-line treatment with celecoxib. CONCLUSION: Although effectiveness of second- and third-line celecoxib use is similar, total cost is lower for second-line. These results suggest that the use of celecoxib before the combination of a non-selective NSAID plus a PPI is relatively cost-effective in the treatment of arthritis pain and support the full benefit listing of celecoxib in Quebec's drug programme.

Purpose: Clinically important deterioration (CID) in chronic obstructive pulmonary disease (COPD) is a novel composite endpoint that assesses disease stability. The association between short-term CID and future economic and quality of life (QoL) outcomes has not been previously assessed. This analysis considers 3-year data from the TOwards a Revolution in COPD Health (TORCH) study, to examine this question. Patients and methods: This post hoc analysis of TORCH (NCT00268216) compared costs and utilities at 3 years among patients without CID (CID-) and with CID (CID+) at 24 weeks. A positive CID status was defined as either: a deterioration in forced expiratory volume in 1 second (FEV1) of ≥100 mL from baseline; or a ≥4-unit increase from baseline in St George's Respiratory Questionnaire (SGRQ) total score; or the incidence of a moderate/severe exacerbation. Patients from all treatment arms were included. Utility change was based on the EQ-5D utility index. Costs were based on healthcare resource utilization from 24 weeks to end of follow-up combined with unit costs for the UK (2016 GBP), and reported as per patient per year (PPPY). Adjusted estimates were generated controlling for baseline characteristics, treatment assignment, and number of CID criteria met. Results: Overall, 3,769 patients completed the study and were included in the analysis (stable CID- patients, n=1,832; unstable CID+ patients, n=1,937). At the end of follow-up, CID- patients had higher mean (95% confidence interval [CI]) utility scores than CID+ patients (0.752 [0.738, 0.765] vs 0.697 [0.685, 0.71]; difference +0.054; P<0.001), and lower costs PPPY (£538 vs £916; difference: £378 [95% CI: £244, £521]; P<0.001). The cost differential was primarily driven by the difference in general hospital ward days (P=0.003). Conclusion: This study demonstrated that achieving early stability in COPD by preventing short-term CID is associated with better preservation of future QoL alongside reduced healthcare service costs.

Background: We assessed the cost-effectiveness of single-inhaler fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI) versus FF/VI or UMEC/VI from a Canadian public healthcare perspective, incorporating data from the IMPACT trial in chronic obstructive pulmonary disease (COPD) (NCT02164513). Methods: Baseline inputs and treatment effects from IMPACT were populated into the validated GALAXY-COPD disease progression model. Canadian unit costs and drug costs (Canadian dollars [C$], 2017) were applied to healthcare resource utilization and treatments. Future costs and health outcomes were discounted at 1.5% annually. Analyses were probabilistic, and outputs included exacerbation rates, costs, and life years (LYs) and quality-adjusted life years (QALYs) gained. Results: Compared with FF/VI and UMEC/VI over a lifetime horizon, the analyses predicted that treatment with FF/UMEC/VI resulted in fewer moderate and severe exacerbations, more LYs and more QALYs gained, with a small incremental cost. The base-case incremental cost-effectiveness ratio (ICER) per QALY gained was C$18,989 (95% confidence interval [CI]: C$14,665, C$25,753) versus FF/VI and C$13,776 (95% CI: C$9787, C$19,448) versus UMEC/VI. FF/UMEC/VI remained cost-effective versus both FF/VI and UMEC/VI in all sensitivity analyses, including in scenario analyses that considered different intervention and comparator discontinuation rates, and treatment effects for subsequent therapy. Conclusion: Treatment with FF/UMEC/VI was predicted to improve outcomes and be a cost-effective treatment option for patients with symptomatic COPD and a history of exacerbations compared with FF/VI or UMEC/VI, in Canada.

BACKGROUND: The Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcomes Results (LEADER) clinical trial demonstrated that liraglutide added to standard-of-care (SoC) therapy for type 2 diabetes (T2D) with established cardiovascular disease (CVD) or elevated cardiovascular (CV) risk was associated with lower rates of death from CVD, nonfatal myocardial infarction (MI), or nonfatal stroke than SoC alone. OBJECTIVE: The objective of this study was to assess the cost-effectiveness (CE) and budget impact of liraglutide vs SoC in T2D patients with established CVD or elevated CV risk, over a lifetime horizon from a US managed care perspective. METHODS: A cohort state-transition model (costs and benefits discounted at 3% per year) was used to predict diabetes-related complications and death (CV and all-cause). Events, treatment effects, and discontinuation rates were from LEADER trial; utility and cost data (US$, 2017) were from literature. Sensitivity analysis explored the impact of uncertainty on results. Additionally, a budget impact analysis was conducted to evaluate the financial impact of liraglutide use in this population, with displacement from dulaglutide, assuming a health care plan with 1 million members. RESULTS: Liraglutide patients experienced 6.3% fewer events, had event-related cost-savings of $15,182, gained additional life-years of 0.67 and quality-adjusted life-years (QALYs) of 0.57, and had additional total costs ($60,928) vs SoC. Liraglutide was cost-effective with an incremental CE ratio of $106,749/QALY which was below the willingness-to-pay threshold of $150,000/QALY accepted by the Institute of Clinical and Economic Research. Liraglutide was cost-effective across all sensitivity analyses, except when the hazard ratio for all-cause mortality varied. The budget impact was neutral, with a per-plan-per-year and per-member-per-month cost-savings of $266,334 and $0.02, respectively. CONCLUSION: From a US-managed care perspective, for T2D patients with established CVD or elevated CV risk, liraglutide is a cost-effective and a budget neutral treatment option for health care plans.
RESUMEN
INTRODUCTION: The cost-effectiveness of long-acting muscarinic antagonist (LAMA) umeclidinium bromide (UMEC) 62.5⯵g as add-on therapy to other maintenance COPD treatments is unknown. METHODS: This analysis assessed the cost-effectiveness of the following in COPD: UMEC + fluticasone furoate/vilanterol 100/25 µg (FF/VI); UMEC + fluticasone propionate/salmeterol 250/50 µg (FP/SAL); and UMEC + several alternative choices of inhaled corticosteroid/long-acting ß2-agonist (ICS/LABA). The model was informed with direct and indirect data from previously published studies, with a UK perspective and a lifetime horizon. Sensitivity analyses were also performed. RESULTS: For the lifetime horizon, compared with FF/VI, FP/SAL and ICS/LABAs, addition of UMEC was associated with incremental costs per quality-adjusted life-years (QALY) of £4050, £7210 and £5780, respectively, and incremental costs per life year gain of £3380, £6020 and £4940. All UMEC-containing regimens resulted in numerically lower exacerbation rates versus comparator regimens over a lifetime horizon. CONCLUSIONS: Addition of UMEC to various ICS/LABA treatments was associated with higher cost than ICS/LABA alone, but was cost-effective in most scenarios.

BACKGROUND AND OBJECTIVES: Exacerbations are important outcomes in COPD both from a clinical and an economic perspective. Most studies investigating predictors of exacerbations were performed in COPD patients participating in pharmacological clinical trials who usually have moderate to severe airflow obstruction. This study was aimed to investigate whether predictors of COPD exacerbations depend on the COPD population studied. METHODS: A network of COPD health economic modelers used data from five COPD data sources - two population-based studies (COPDGene® and The Obstructive Lung Disease in Norrbotten), one primary care study (RECODE), and two studies in secondary care (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoint and UPLIFT) - to estimate and validate several prediction models for total and severe exacerbations (= hospitalization). The models differed in terms of predictors (depending on availability) and type of model. RESULTS: FEV1% predicted and previous exacerbations were significant predictors of total exacerbations in all five data sources. Disease-specific quality of life and gender were predictors in four out of four and three out of five data sources, respectively. Age was significant only in the two studies including secondary care patients. Other significant predictors of total exacerbations available in one database were: presence of cough and wheeze, pack-years, 6-min walking distance, inhaled corticosteroid use, and oxygen saturation. Predictors of severe exacerbations were in general the same as for total exacerbations, but in addition low body mass index, cardiovascular disease, and emphysema were significant predictors of hospitalization for an exacerbation in secondary care patients. CONCLUSIONS: FEV1% predicted, previous exacerbations, and disease-specific quality of life were predictors of exacerbations in patients regardless of their COPD severity, while age, low body mass index, cardiovascular disease, and emphysema seem to be predictors in secondary care patients only.

INTRODUCTION: Chronic obstructive pulmonary disease is associated with a high healthcare resource and cost burden. Healthcare resource utilization was analyzed in patients with symptomatic chronic obstructive pulmonary disease at risk of exacerbations in the FULFIL study. Patients received either once-daily, single inhaler triple therapy (fluticasone furoate/umeclidinium/vilanterol) 100 µg/62.5 µg/25 µg or twice-daily dual inhaled corticosteroid/long-acting beta agonist therapy (budesonide/formoterol) 400 µg/12 µg. METHODS: FULFIL was a phase III, randomized, double-blind, double-dummy, multicenter study. Unscheduled contacts with healthcare providers were recorded by patients in a daily electronic diary; the costs of healthcare resource utilization were calculated post hoc using UK reference costs. RESULTS: Over 24 weeks, slightly fewer patients who received fluticasone furoate/umeclidinium/vilanterol (169/911; 18.6%) required contacts with healthcare providers compared with budesonide/formoterol (180/899; 20.0%). Over 52 weeks in an extension population, fewer patients who received fluticasone furoate/umeclidinium/vilanterol required unscheduled contacts with healthcare providers compared with budesonide/formoterol (25.2% vs. 32.7%). Non-drug costs per treated patient per year were lower in the fluticasone furoate/umeclidinium/vilanterol group than the budesonide/formoterol group over 24 and 52 weeks (£653.80 vs. £763.32 and £749.22 vs. £988.03, respectively), with the total annualized cost over 24 weeks being slightly greater for fluticasone furoate/umeclidinium/vilanterol than budesonide/formoterol (£1,289.35 vs. £1,267.45). CONCLUSIONS: This healthcare resource utilization evidence suggests that, in a clinical trial setting over a 24- or 52-week timeframe, non-drug costs associated with management of a single inhaler fluticasone furoate/umeclidinium/vilanterol are lower compared with twice-daily budesonide/formoterol.

BACKGROUND: The recent joint International Society for Pharmacoeconomics and Outcomes Research / Society for Medical Decision Making Modeling Good Research Practices Task Force emphasized the importance of conceptualizing and validating models. We report a new model of chronic obstructive pulmonary disease (COPD) (part of the Galaxy project) founded on a conceptual model, implemented using a novel linked-equation approach, and internally validated. METHODS: An expert panel developed a conceptual model including causal relationships between disease attributes, progression, and final outcomes. Risk equations describing these relationships were estimated using data from the Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) study, with costs estimated from the TOwards a Revolution in COPD Health (TORCH) study. Implementation as a linked-equation model enabled direct estimation of health service costs and quality-adjusted life years (QALYs) for COPD patients over their lifetimes. Internal validation compared 3 years of predicted cohort experience with ECLIPSE results. RESULTS: At 3 years, the Galaxy COPD model predictions of annual exacerbation rate and annual decline in forced expiratory volume in 1 second fell within the ECLIPSE data confidence limits, although 3-year overall survival was outside the observed confidence limits. Projections of the risk equations over time permitted extrapolation to patient lifetimes. Averaging the predicted cost/QALY outcomes for the different patients within the ECLIPSE cohort gives an estimated lifetime cost of £25,214 (undiscounted)/£20,318 (discounted) and lifetime QALYs of 6.45 (undiscounted/5.24 [discounted]) per ECLIPSE patient. CONCLUSIONS: A new form of model for COPD was conceptualized, implemented, and internally validated, based on a series of linked equations using epidemiological data (ECLIPSE) and cost data (TORCH). This Galaxy model predicts COPD outcomes from treatment effects on disease attributes such as lung function, exacerbations, symptoms, or exercise capacity; further external validation is required.
