Cost-effectiveness of empagliflozin as add-on to standard of care for chronic kidney disease management in the United Kingdom.

OBJECTIVE: The sodium-glucose co-transporter-2 inhibitor empagliflozin was approved for treatment of adults with chronic kidney disease (CKD) on the basis of its demonstrated ability to slow CKD progression and reduce the risk of cardiovascular death. This analysis was performed to assess the cost-effectiveness of empagliflozin plus standard of care (SoC) vs SoC alone in the treatment of CKD in the UK. METHODS: A comprehensive, patient-level CKD progression model that simulates the evolution of risk factors for disease progression based on CKD-specific equations and clinical data was used to project a broad range of CKD-related complications. Patient baseline characteristics, distribution across Kidney Disease Improving Global Outcomes (KDIGO) health states, and changes in estimated glomerular filtration rate (eGFR), urine albumin-creatinine ratio (uACR), and other parameters while on treatment were derived from the EMPA-KIDNEY trial. UK cost and utilities/disutilities were sourced from the literature. Univariate and probabilistic sensitivity analyses were conducted. Annual discounting of 3.5% was applied on costs and outcomes. RESULTS: Over a 50-year horizon, SoC resulted in per-patient costs, life years, and QALYs of £95,930, 8.55, and 6.28, respectively. Empagliflozin plus SoC resulted in an incremental gain in life years (+1.04) and QALYs (+0.84), while decreasing per-patient costs by £6,019. Empagliflozin was more effective and less costly (dominant) with a net monetary benefit of £22,849 at the willingness-to-pay threshold of £20,000. Although treatment cost was higher for empagliflozin, this was more than offset by savings in kidney replacement therapy. Empagliflozin remained highly cost-effective in patients with and without diabetes, and across scenario and sensitivity analyses. LIMITATIONS: This analysis is limited by reliance on short-term clinical trial data and by uncertainties in modelling CKD progression. CONCLUSIONS: Empagliflozin as an add-on to SoC for treatment of adults with CKD represents cost-effective use of UK National Health Service (NHS) resources.

Cost-effectiveness of the tubeless automated insulin delivery system vs standard of care in the management of type 1 diabetes in the United States.

BACKGROUND: A tubeless, on-body automated insulin delivery (AID) system (Omnipod 5 Automated Insulin Delivery System) demonstrated improved glycated hemoglobin A1c levels and increased time in range (70 mg/dL to 180 mg/dL) for both adults and children with type 1 diabetes in a 13-week multicenter, single-arm study. OBJECTIVE: To assess the cost-effectiveness of the tubeless AID system compared with standard of care (SoC) in the management of type 1 diabetes (T1D) in the United States. METHODS: Cost-effectiveness analyses were conducted from a US payer's perspective, using the IQVIA Core Diabetes Model (version 9.5), with a time horizon of 60 years and an annual discount of 3.0% on both costs and effects. Simulated patients received either tubeless AID or SoC, the latter being defined as either continuous subcutaneous insulin infusion (86% of patients) or multiple daily injections. Two cohorts (children: <18 years; adults: ≥18 years) of patients with T1D and 2 thresholds for nonsevere hypoglycemia (nonsevere hypoglycemia event [NSHE] <54 mg/dL and <70 mg/dL) were considered. Baseline cohort characteristics and treatment effects of different risk factors for tubeless AID were sourced from the clinical trial. Utilities and cost of diabetes-related complications were obtained from published sources. Treatment costs were derived from US national database sources. Scenario analyses and probabilistic sensitivity analyses were performed to test the robustness of the results. RESULTS: Treating children with T1D with tubeless AID, considering an NSHE threshold of less than 54 mg/dL, brings incremental life-years (1.375) and quality-adjusted life-years (QALYs) (1.521) at an incremental cost of $15,099 compared with SoC, resulting in an incremental cost-effectiveness ratio of $9,927 per QALY gained. Similar results were obtained for adults with T1D assuming an NSHE threshold of less than 54 mg/dL (incremental cost-effectiveness ratio = $10,310 per QALY gained). Furthermore, tubeless AID is a dominant treatment option for children and adults with T1D assuming an NSHE threshold of less than 70 mg/dL compared with SoC. The probabilistic sensitivity analyses results showed that compared with SoC, in both children and adults with T1D, tubeless AID was cost-effective in more than 90% of simulations, assuming a willingness-to-pay threshold of $100,000 per QALY gained. The key drivers of the model were the cost of ketoacidosis, duration of treatment effect, threshold of NSHE, and definition of severe hypoglycemia. CONCLUSIONS: The current analyses suggest that the tubeless AID system can be considered a cost-effective treatment compared with SoC in people with T1D from a US payer's perspective.

The Cost-Effectiveness of Subcutaneous Semaglutide Versus Empagliflozin in Type 2 Diabetes Uncontrolled on Metformin Alone in Denmark.

INTRODUCTION: International and Danish guidelines recommend the use of glucagon-like peptide 1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter 2 (SGLT-2) inhibitors already in second line in the management of type 2 diabetes (T2D). The objective of this study was to evaluate the long-term cost-effectiveness (CE) of subcutaneous (SC) semaglutide (GLP-1 RA) versus empagliflozin (SGLT-2 inhibitor) in individuals with T2D uncontrolled on metformin alone from a Danish payer's perspective. METHODS: Cost-effectiveness analyses (CEA) were conducted from a Danish payer's perspective, using the IQVIA Core Diabetes model (CDM 9.5), with a time horizon of 50 years and an annual discount of 4% on costs and effects. Patients received either SC semaglutide or empagliflozin, in addition to metformin, until HbA1c threshold of 7.5% (58 mmol/mol) was reached, following which treatment intensification with insulin glargine in addition to empagliflozin or SC semaglutide plus metformin was considered. Baseline cohort characteristics and treatment effects were sourced from a published CEA. Utilities and cost of diabetes-related complications were also obtained from published sources. Treatment costs were derived from Danish official sources. Scenario analyses were also performed to test the accuracy of the base case results. RESULTS: Individuals with T2D on SC semaglutide plus metformin gained 0.065 life-years (LYs) and 0.130 quality-adjusted LYs (QALYs), respectively, at an incremental cost of DKK 96,923 (€ 13,031) compared to empagliflozin plus metformin, resulting in an incremental cost-effectiveness ratio (ICER) of DKK 745,561(€ 100,239) per QALY gained. The probabilistic sensitivity analysis (PSA) results showed that the SC semaglutide plus metformin was cost-effective in 19% of simulations assuming a willingness-to-pay (WTP) threshold of DKK 357,100 (€ 48,011)/QALY gained. Duration of therapy with SC semaglutide seems the key driver of results. CONCLUSION: The current analyses suggest that SC semaglutide plus metformin is not cost-effective compared to empagliflozin plus metformin from a Danish payer's perspective.

Exploring Structural Uncertainty and Impact of Health State Utility Values on Lifetime Outcomes in Diabetes Economic Simulation Models: Findings from the Ninth Mount Hood Diabetes Quality-of-Life Challenge.

BACKGROUND: Structural uncertainty can affect model-based economic simulation estimates and study conclusions. Unfortunately, unlike parameter uncertainty, relatively little is known about its magnitude of impact on life-years (LYs) and quality-adjusted life-years (QALYs) in modeling of diabetes. We leveraged the Mount Hood Diabetes Challenge Network, a biennial conference attended by international diabetes modeling groups, to assess structural uncertainty in simulating QALYs in type 2 diabetes simulation models. METHODS: Eleven type 2 diabetes simulation modeling groups participated in the 9th Mount Hood Diabetes Challenge. Modeling groups simulated 5 diabetes-related intervention profiles using predefined baseline characteristics and a standard utility value set for diabetes-related complications. LYs and QALYs were reported. Simulations were repeated using lower and upper limits of the 95% confidence intervals of utility inputs. Changes in LYs and QALYs from tested interventions were compared across models. Additional analyses were conducted postchallenge to investigate drivers of cross-model differences. RESULTS: Substantial cross-model variability in incremental LYs and QALYs was observed, particularly for HbA1c and body mass index (BMI) intervention profiles. For a 0.5%-point permanent HbA1c reduction, LY gains ranged from 0.050 to 0.750. For a 1-unit permanent BMI reduction, incremental QALYs varied from a small decrease in QALYs (-0.024) to an increase of 0.203. Changes in utility values of health states had a much smaller impact (to the hundredth of a decimal place) on incremental QALYs. Microsimulation models were found to generate a mean of 3.41 more LYs than cohort simulation models (P = 0.049). CONCLUSIONS: Variations in utility values contribute to a lesser extent than uncertainty captured as structural uncertainty. These findings reinforce the importance of assessing structural uncertainty thoroughly because the choice of model (or models) can influence study results, which can serve as evidence for resource allocation decisions.HighlightsThe findings indicate substantial cross-model variability in QALY predictions for a standardized set of simulation scenarios and is considerably larger than within model variability to alternative health state utility values (e.g., lower and upper limits of the 95% confidence intervals of utility inputs).There is a need to understand and assess structural uncertainty, as the choice of model to inform resource allocation decisions can matter more than the choice of health state utility values.

The cost-effectiveness of oral semaglutide versus empagliflozin in Type 2 diabetes in Denmark.

Aim: To evaluate the cost-effectiveness of oral semaglutide+metformin versus empagliflozin+metformin in people with Type 2 diabetes uncontrolled on msetformin alone. Materials and methods: The IQVIA Core Diabetes Model was populated with efficacy data from a head-to-head study between oral semaglutide+metformin and empagliflozin+metformin. Danish costs and quality-of-life data were sourced from literature. Price per day was Danish Krone (DKK) 25.53 for oral semaglutide and DKK11.40 for empagliflozin. Discounting was fixed at 4%. Scenario and sensitivity analyses were performed. Results: Over a lifetime, Core Diabetes Model projected 8.78 and 8.75 quality-adjusted life-years and a total cost of DKK 447,633 and DKK 387,786, thereby generating an incremental cost-effectiveness ratio of DKK 1,930,548 for oral semaglutide+metformin versus empagliflozin+metformin. Scenario and sensitivity analyses showed the robustness of the outcomes. Duration of treatment with oral semaglutide is the key driver of the analyses. Conclusion: Oral semaglutide+metformin seems not cost effective versus empagliflozin+metformin in patients uncontrolled on metformin in Denmark.

Cost-Effectiveness of iGlarLixi Versus iDegLira in Type 2 Diabetes Mellitus Inadequately Controlled by GLP-1 Receptor Agonists and Oral Antihyperglycemic Therapy.

INTRODUCTION: The fixed-ratio combinations (FRCs) of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and basal insulin, insulin glargine 100 U/mL plus lixisenatide (iGlarLixi), and insulin degludec plus liraglutide (iDegLira), have demonstrated safety and efficacy in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on GLP-1 RAs. However, a comparative cost-effectiveness analysis between these FRCs from a UK Health Service perspective has not been conducted. METHODS: The IQVIA Core Diabetes Model was used to estimate lifetime costs and outcomes in patients with T2DM receiving iGlarLixi (based on the LixiLan-G trial) versus iDegLira (based on relative treatment effects from an indirect treatment comparison using data from DUAL III). Utilities, medical costs, and costs of diabetes-related complications were derived from literature. Model outputs included costs and quality-adjusted life years (QALYs). Incremental cost-effectiveness ratios were calculated with a local willingness-to-pay threshold of £20,000 per QALY. Extensive scenario, one-way sensitivity, and probabilistic sensitivity analyses were conducted to evaluate the robustness of the model. RESULTS: iGlarLixi was less costly (iGlarLixi, £30,011; iDegLira, £40,742), owing to lower acquisition costs, and similar in terms of QALYs gained (iGlarLixi, 8.437; iDegLira, 8.422). Extensive scenario and sensitivity analyses supported the base case findings. CONCLUSION: In patients with T2DM and inadequate glycemic control despite GLP-1 RAs, use of iGlarLixi was associated with substantial cost savings and comparable utility outcomes. iGlarLixi can be considered as cost-effective versus iDegLira from the UK Health Service perspective.

Cost-effectiveness of empagliflozin in patients with type 2 diabetes and established cardiovascular disease in China.

BACKGROUND: In several cardiovascular outcome trials (CVOTs), empagliflozin (SGLT-2 inhibitor), sitagliptin (DPP-4 inhibitor) and liraglutide (GLP-1 receptor agonist) + standard of care (SoC) were compared to SoC in patients with type 2 diabetes and established cardiovascular disease (CVD). This study assessed the cost-effectiveness (CE) of empagliflozin + SoC in comparison to sitagliptin + SoC and liraglutide + SoC based on the respective CVOT. METHODS: The IQVIA Core Diabetes Model (CDM) was calibrated to reproduce the CVOT outcomes. EMPA-REG OUTCOME baseline characteristics and CVOT specific treatment effects on risk factors for cardiovascular disease (HbA1c, BMI, blood pressure, lipids) were applied. Three-year observed cardiovascular events of empagliflozin + SoC versus sitagliptin + SoC and liraglutide + SoC were derived from EMPA-REG OUTCOME and an indirect treatment comparison. Relative risk adjustments to calibrate the CDM were obtained after a trial and error process to match as closely the observed and CDM-predicted outcomes. The drug-specific treatment effects were considered up until HbA1c reached 8.5% and treatment switch occurred. After this switch, the United Kingdom Prospective Diabetes Study 82 risk equations predicted events based on co-existing risk factors and treatment intensification to basal bolus insulin were applied. The analysis was conducted from the perspective of the Chinese healthcare system applying 3% discounting. The time horizon was lifelong. RESULTS: Empagliflozin + SoC provides additional Quality Adjusted Life years (QALY + 0.564) for an incremental cost of 42,497RMB (US$6053) compared to sitagliptin + SoC, resulting in an Incremental Cost Utility Ratio of 75,349RMB (US$10,732), thus below the willingness-to-pay threshold of 212,676RMB, corresponding to three times the Gross Domestic Product in China (2019). Compared to liraglutide + SoC, empagliflozin + SoC use leads to 0.211QALY gained and cost savings of 71,427RMB (US$10,173) and is as such dominant. Scenario and probabilistic sensitivity analyses demonstrated the robustness of the results. CONCLUSION: Results suggest that empagliflozin + SoC is cost-effective compared to sitagliptin + SoC and liraglutide + SoC at a willingness-to-pay threshold of 212,676RMB ($30,292)/QALY.

Potential clinical and economic impact of optimised maintenance therapy on discharged patients with COPD after hospitalisation for an exacerbation in China.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) exacerbations requiring hospitalisation are a considerable burden, both clinically and economically. Although long-acting maintenance therapy is recommended in both the GOLD (Global Initiative for Chronic Obstructive Lung Disease) and Chinese COPD guidelines, proper implementation is lacking. The objective of this study was to assess the clinical and economic impact of prescribing long-acting maintenance therapy to discharged patients with COPD after hospitalisation for an exacerbation in China by using an outcomes model. DESIGN: This health economic analysis was conducted using a Markov cohort model from the Chinese healthcare payer perspective. Two health states (alive and dead) were modelled, and exacerbations were included as possible events. SETTING: The target population was Chinese patients with COPD, >40 years of age, who were hospitalised for an exacerbation, with 1 year of follow-up. A recent COPD national prevalence study was referenced for population calculations. INTERVENTION: A hypothetical future scenario, where 100% of patients would receive long-acting maintenance therapy after hospitalisation for an exacerbation, was compared with the current scenario, in which only 38.5% of patients are receiving long-acting maintenance therapy after hospitalisation. OUTCOME MEASURES: Number of exacerbations, deaths and medical costs were measured. RESULTS: We estimated that there were approximately 4 million Chinese patients with COPD who were hospitalised annually due to an exacerbation. By prescribing long-acting maintenance therapy, our model predicted that 917 360 exacerbations and 4034 deaths could be avoided, translating into cost savings of ¥3.5 billion (US$0.5 billion). Scenario analysis also showed that if the rate of exacerbations requiring hospitalisation was higher than our base case analysis, cost savings could reach up to ¥10.7 billion (US$1.5 billion). CONCLUSION: Administering long-acting maintenance therapy to more patients with COPD at hospital discharge could considerably reduce exacerbations and healthcare spending in China.

Cost-effectiveness analysis of empagliflozin compared with glimepiride in patients with Type 2 diabetes in China.

Aim: The study assesses the cost-effectiveness of empagliflozin versus glimepiride in patients with Type 2 diabetes and uncontrolled by metformin alone in China, based on the EMPA-REG H2H-SU trial. Materials & methods: A calibrated version of the IQVIA Core Diabetes Model was used. Cost of complications and utility were taken from literature. The Chinese healthcare system perspective and 5% discounting rates were applied. Results: Empagliflozin+metformin provides additional quality-adjusted life-years (0.317) driven by a reduction in the number of cardiovascular and renal events, for an additional cost of $1382 (CNY9703) compared with glimepiride+metformin. Conclusion: Empagliflozin is cost-effective treatment versus glimepiride applying a threshold of $30,290 (CNY212,676).

Patient and caregiver productivity loss and indirect costs associated with cardiovascular events in Portugal.

OBJECTIVES: To present the Portuguese results of a multi-country cross-sectional survey aiming to estimate productivity loss in the first year after an acute coronary syndrome (ACS) or stroke. METHODS: Patients previously hospitalized for ACS or stroke were enrolled during a routine cardiology/neurology visit 3-12 months after the index event and ≥4 weeks after returning to work. Productivity loss for the patient and the caregiver in the previous four weeks were reported by the patient using the validated iMTA Productivity Cost Questionnaire (iPCQ). Hours lost were converted into eight-hour work days and prorated to one year, combined with initial hospitalization and sick leave, and valued according to Portuguese labor costs. RESULTS: The analysis included 39 employed patients with ACS (mean age 51 years, 80% men, 95% with myocardial infarction, mean left ventricular ejection fraction 55%) and 31 with stroke (mean age 50 years, 80% men, all ischemic, 77% with modified Rankin Scale 0-1); 41% of ACS and 10% of stroke patients had a history of cardiovascular disease. Mean (SD) productivity loss for patients and caregivers was 47 (62) work days for ACS and 76 (101) work days for stroke. ACS patients lost 37 (39) and caregivers lost 10 (42) work days. Stroke patients and caregivers lost 65 (78) and 12 (38) work days, respectively. Total mean indirect cost per case was €5403 (€7095) and €8726 (€11558) for employed patients with ACS and stroke, respectively. CONCLUSIONS: The annual proportions of productive time lost by employed patients due to ACS and stroke in Portugal were 17% and 27%, respectively. Caregivers of these patients lost about 5% of their annual productive time.

Multicenter Prospective Evaluation of Parenteral Nutrition Preparation Time and Resource Utilization: 3-Chamber Bags Compared With Hospital Pharmacy-Compounded Bags.

BACKGROUND: Parenteral nutrition (PN) is a complex and costly therapy that places significant demands on healthcare resources. Commercially manufactured 3-chamber bags (3CBs) offer potential time and cost advantages compared with hospital pharmacy-compounded bags (HCBs); however, no data are yet available from studies comparing these delivery systems in US hospitals. The primary aim of this study was to evaluate the PN preparation time and resource utilization required for 3CBs compared with HCBs in US hospitals. METHODS: A prospective, multicenter, time and motion study was performed to evaluate the time from transcription to completion of PN preparation and costs for 3CBs compared with HCBs. The cost per bag included labor, PN products, medical consumables, and equipment. RESULTS: One hundred thirty-six PN prescriptions were prepared during the study (66 prescriptions for 3CBs and 70 prescriptions for HCBs). The mean ± standard deviation total time required for transcription, review, validation, and preparation of PN was 5.5 ± 1.3 minutes for 3CBs vs 14.3 ± 6.2 minutes for HCBs (P < .001). The mean total cost per PN bag was $81.60 for 3CBs and $131.17 for HCBs (mean difference, -$49.57). CONCLUSION: Commercial 3CBs reduced staff time by 62% and direct costs by 37% compared with HCBs. The results demonstrate that 3CBs offer potential cost-savings for hospitalized patients who require PN in US hospitals.

Evaluating the Ability of Economic Models of Diabetes to Simulate New Cardiovascular Outcomes Trials: A Report on the Ninth Mount Hood Diabetes Challenge.

OBJECTIVES: The cardiovascular outcomes challenge examined the predictive accuracy of 10 diabetes models in estimating hard outcomes in 2 recent cardiovascular outcomes trials (CVOTs) and whether recalibration can be used to improve replication. METHODS: Participating groups were asked to reproduce the results of the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME) and the Canagliflozin Cardiovascular Assessment Study (CANVAS) Program. Calibration was performed and additional analyses assessed model ability to replicate absolute event rates, hazard ratios (HRs), and the generalizability of calibration across CVOTs within a drug class. RESULTS: Ten groups submitted results. Models underestimated treatment effects (ie, HRs) using uncalibrated models for both trials. Calibration to the placebo arm of EMPA-REG OUTCOME greatly improved the prediction of event rates in the placebo, but less so in the active comparator arm. Calibrating to both arms of EMPA-REG OUTCOME individually enabled replication of the observed outcomes. Using EMPA-REG OUTCOME-calibrated models to predict CANVAS Program outcomes was an improvement over uncalibrated models but failed to capture treatment effects adequately. Applying canagliflozin HRs directly provided the best fit. CONCLUSIONS: The Ninth Mount Hood Diabetes Challenge demonstrated that commonly used risk equations were generally unable to capture recent CVOT treatment effects but that calibration of the risk equations can improve predictive accuracy. Although calibration serves as a practical approach to improve predictive accuracy for CVOT outcomes, it does not extrapolate generally to other settings, time horizons, and comparators. New methods and/or new risk equations for capturing these CV benefits are needed.

Long-Term Cost-Effectiveness Analyses of Empagliflozin Versus Oral Semaglutide, in Addition to Metformin, for the Treatment of Type 2 Diabetes in the UK.

INTRODUCTION: International guidelines recommend treatment with a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or glucagon-like peptide-1 (GLP-1) receptor agonist for treatment intensification in type 2 diabetes mellitus (T2DM) patients with progression on metformin. In the randomised, controlled, Peptide Innovation for Early Diabetes Treatment (PIONEER) 2 trial, the SGLT-2 inhibitor empagliflozin was compared with the GLP-1 receptor agonist oral semaglutide, in addition to metformin. The aim of the current study was to assess the long-term cost-effectiveness of empagliflozin 25 mg versus oral semaglutide 14 mg, in addition to metformin, for T2DM patients in the UK. METHODS: Analyses were conducted from the UK healthcare payer perspective, using the IQVIA Core Diabetes model, with a time horizon of 50 years. Patients received either empagliflozin or oral semaglutide, in addition to metformin, until Hba1c threshold of 7.5% (58 mmol/mol) was exceeded, following which treatment intensification with insulin glargine in addition to empagliflozin or oral semaglutide plus metformin was assumed. Baseline cohort characteristics and 52-week treatment effects were derived from the PIONEER 2 trial. Treatment effects of empagliflozin and GLP-1 receptor agonists on hospitalisation for heart failure (hHF) were based on the Empagliflozin Comparative Effectiveness and Safety (EMPRISE) real-world study. Utilities, treatment costs and costs of diabetes-related complications were obtained from published sources. RESULTS: Direct costs for empagliflozin plus metformin were considerably lower than those for oral semaglutide plus metformin (by more than GBP 6000). Compared with oral semaglutide plus metformin, empagliflozin plus metformin was a cost-effective treatment for T2DM patients in all scenarios tested. Probabilistic sensitivity analysis showed cost-effectiveness in > 95% of the iterations using a threshold of 20,000 GBP/QALY. CONCLUSION: Empagliflozin 25 mg is a cost-effective treatment option versus oral semaglutide 14 mg, when used in addition to metformin, for the treatment of T2DM patients in the UK.

Cost-effectiveness of empagliflozin compared with liraglutide based on cardiovascular outcome trials in Type II diabetes.

Aim: Cost-effectiveness (CE) analysis of empagliflozin+standard of care (SoC) compared with SoC and liraglutide+SoC, in patients with Type II diabetes and established cardiovascular disease, was conducted using evidence from cardiovascular outcomes trials. Methods: The IQVIA Core Diabetes Model was calibrated to predict same outcomes observed in EMPA-REG OUTCOME and LEADER trials. Three-year observed cardiovascular events of SoC, empagliflozin+SoC and liraglutide+SoC were derived from EMPA-REG OUTCOME trial and an indirect comparison. Time horizon was 50 years and the UK payer perspective was taken. Results: Empagliflozin+SoC dominated liraglutide+SoC with greater quality-adjusted life years and reduced costs. Base-case incremental CE ratio of 6428 GBP/QALY was observed for empagliflozin+SoC versus SoC. Conclusion: Results suggest that empagliflozin+SoC is cost effective versus SoC and liraglutide+SoC.

Cost-Effectiveness Analysis of Empagliflozin in Comparison to Sitagliptin and Saxagliptin Based on Cardiovascular Outcome Trials in Patients with Type 2 Diabetes and Established Cardiovascular Disease.

INTRODUCTION: In the cardiovascular outcome trials (CVOT) EMPA-REG OUTCOME, TECOS and SAVOR-TIMI 53, empagliflozin [sodium/glucose cotransporter 2 (SGLT2) inhibitor], sitagliptin and saxagliptin [both dipeptidyl peptidase 4 (DPP4) inhibitors] + standard of care (SoC) were compared to SoC in patients with type 2 diabetes and established cardiovascular disease (CVD). This study assessed the cost-effectiveness (CE) of empagliflozin + SoC in comparison to sitagliptin + SoC and saxagliptin + SoC based on the respective CVOT. METHODS: The IQVIA Core Diabetes Model (CDM) was calibrated to reproduce the CVOT outcomes. EMPA-REG OUTCOME baseline characteristics and CVOT specific treatment effects on risk factors for cardiovascular disease [glycated haemogloblin A1c (HbA1c), body mass index (BMI), blood pressure, lipids] were applied. Three-year observed cardiovascular events of empagliflozin + SoC versus sitagliptin + SoC and saxagliptin + SoC were derived from EMPA-REG OUTCOME and an indirect treatment comparison. Relative risk (RR) adjustments to calibrate the CDM were estimated after consecutive attempts of running the model until the observed and CDM-predicted outcomes matched closely. The drug-specific treatment effects were considered up until treatment switch (when HbA1c reached 8.5%), after which, the United Kingdom Prospective Diabetes Study (UKPDS) 82 risk equations predicted events based on co-existing risk factors and treatment intensification to basal-bolus insulin were applied. The analysis was conducted from the perspective of the UK National Health Service. Costs and quality of life data were derived from UK national sources and published literature. A 50-year time horizon and discount rate of 3.5% were applied. RESULTS: The CDM projected quality-adjusted life years (QALYs) of 6.408, 5.917 and 5.704 and total costs of 50,801 GBP, 47,627 GBP and 48,071 GBP for empagliflozin + SoC, sitagliptin + SoC and saxagliptin + SoC, respectively. The incremental CE ratio (ICER) of empagliflozin + SoC versus sitagliptin + SoC and saxagliptin + SoC was 6464 GBP/QALY and 3878 GBP/QALY, respectively. One-way and probabilistic sensitivity analyses demonstrated the robustness of the results. CONCLUSION: Results suggest that empagliflozin + SoC is cost-effective compared to sitagliptin + SoC and saxagliptin + SoC at a willingness to pay threshold of 20,000 GBP/QALY.

Cost-effectiveness of physical activity in the management of COPD patients in the UK.

BACKGROUND: While the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines advise exercise to reduce disease progression, little investment in promoting physical activity (PA) is made by health care authorities. The purpose of this study was to estimate the cost-effectiveness of regular PA vs sedentary lifestyle in people with COPD in the UK. METHODS: Efficacy, quality of life, and economic evidence on the PA effects in COPD patients were retrieved from literature to serve as input for a Markov microsimulation model comparing a COPD population performing PA vs a COPD population with sedentary lifestyle. The GOLD classification defined the model health states. For the base case, the cost of PA was estimated at zero, a lifetime horizon was used, and costs and effects were discounted at 3.5%. Analyses were performed from the UK National Health Service (NHS) perspective. Uncertainty around inputs and assumptions were explored via scenario and sensitivity analyses, including a cost threshold analysis. Outcomes were cost/quality-adjusted life year (QALY) gained and cost/year gained. RESULTS: Based on our model, the effects of PA in the UK COPD population would be lower mortality (-6%), fewer hospitalizations (-2%), gains in years (+0.82) and QALYs (+0.66), and total cost savings of £2,568. The cost/QALY and cost/year gained were dominant. PA was cost-saving at costs <£35/month and cost-effective at cost <£202/month. The main model drivers were age and PA impact on death and hospital-treated exacerbations. CONCLUSION: Including PA in the management of COPD leads to long-term clinical benefits. If the NHS promotes only exercise via medical advice, this would lead to health care cost savings. If the NHS chose to fund PA, it would still likely be cost-effective.

Assessing the Burden of Type 2 Diabetes in China Considering the Current Status-Quo Management and Implications of Improved Management Using a Modeling Approach.

BACKGROUND: Recent estimates from the International Diabetes Federation Diabetes Atlas have quantified the total annual expenditure for diabetes in China to be between 354 and 611 billion Chinese yuan (¥) (2015). OBJECTIVES: To use a modeling approach to assess the current and possible future diabetes burden in China on the basis of the current standard of type 2 diabetes (T2D) management (status quo [SQ]) and a series of hypothetical improved management strategies. METHODS: The IQVIA CORE Diabetes Model was used to evaluate the economic burden of T2D in China on the basis of assumptions reflecting the current SQ of T2D management and a number of stepwise improvements. SQ was defined as a scenario in which T2D diagnosis is delayed by 4 years, treatment escalation to maintain glucose control occurs at a 9% glycated hemoglobin (HbA1c) threshold, and there is an overall 60% adherence rate. Stepwise improvements considered immediate diagnosis, declining levels of HbA1c escalation thresholds to 7.0%, and improvements in adherence rate to 80% and 100%. The CORE Diabetes Model was applied on per-capita level to project lifetime costs and clinical outcomes of newly diseased T2D individuals in the Chinese setting. Model outcomes were subsequently annualized and extrapolated to Chinese national level considering the total number of diagnosed individuals with T2D in China. RESULTS: The total annual direct costs attributable to diagnosed T2D in China reflecting current SQ management were estimated at ¥621 billion. Scenarios exploring stepwise improvements from SQ estimated annual net savings of ¥35, ¥35, ¥60, ¥71, ¥75, and ¥106 billion for scenarios exploring immediate diagnosis, HbA1c threshold reductions to 8.0% and 7.0%, adherence rate increase to 80% and 100%, and cardiovascular risk factor control in concordance with clinical guidelines, respectively. Net savings resulted from reduced costs to treat diabetes complications (¥38, ¥67, ¥124, ¥141, ¥161, and ¥212 billion) and excess treatment costs alongside stepwise management improvements (¥4, ¥32, ¥65, ¥69, ¥86, and ¥107 billion). Per-capita life expectancy was increased by 0.26, 0.68, 1.33, 1.47, 1.69, and 3.21 years, respectively. CONCLUSIONS: Improved T2D management strategies can help to decrease the financial burden of the disease and increase life expectancy of individuals with T2D.

Cost-effectiveness analysis of the SAPIEN 3 TAVI valve compared with surgery in intermediate-risk patients.

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) has become the therapy of choice for treating severe aortic stenosis in patients at high-risk for surgery or where it is considered too risky to attempt. This uptake varies across geographies however, and its cost or value has frequently been cited as the reason for this. We sought to evaluate the potential cost and clinical impact of TAVI in intermediate risk patients from a French collective perspective. MATERIALS AND METHODS: The analysis was performed using a novel Markov model with data derived from the PARTNER II randomized controlled trial for survival, clinical event rates, and quality-of-life. The simulated time horizon was 15 years, costs were from French sources and presented in 2016 Euros. Discounting of all outcomes was at 4% annually and the effect of uncertainty in model parameters was explored by deterministic and probabilistic sensitivity analysis (PSA). RESULTS: In comparison to surgery, TAVI resulted in improved clinical outcomes (life expectancy and quality-adjusted life expectancy) and lower costs over a lifetime time horizon. The base case results showed increases of 0.42 years and 0.41 QALYs with lifetime cost savings of €439 for TAVI compared to surgery. PSA results showed a >50% likelihood of cost-effectiveness at €0 willingness-to-pay and a 100% likelihood at ∼€15,000. LIMITATIONS: Clinically, survival projections are based on limited follow-up data and introduce uncertainty into the outcomes from the model. Economically, procedure costs are derived from a heterogeneous mix of patient risk groups, although this is much more likely to bias against TAVI and under-estimate overall cost savings. CONCLUSIONS: In our analyses of intermediate risk patients, TAVI is associated with superior clinical outcomes compared to surgery and is cost saving. It could be expected that cost savings are conservative and likely to increase over time.

Cost-Effectiveness of rFVIIa versus pd-aPCC in the Management of Mild to Moderate Bleeds in Pediatric Patients with Hemophilia A with Inhibitors in Mexico.

OBJECTIVE: To compare the costs and clinical consequences of treating mild-to-moderate joint bleeds with recombinant activated factor VII (rFVIIa) versus plasma-derived activated prothrombin complex concentrate (pd-aPCC) in pediatric patients with hemophilia A with inhibitors in Mexico. METHODS: A cost-effectiveness model was developed using TreeAge Pro v14.2.2 software (licensed in the USA) and adapted from a previously published model, with adjustments to reflect local clinical practice. Expert opinion was sought regarding patients' clinical management and resource utilization in Mexico to ensure that the current model was appropriate and relevant. The model compared rFVIIa and pd-aPCC for the treatment of mild-to-moderate joint bleeds in children <14 years old (assumed average weight: 30 kg). The analysis outcome was incremental cost per resolved mild-to-moderate joint bleed. One-way sensitivity analysis and probabilistic sensitivity analysis were used to assess specific assumptions and to address any uncertainty in the model. RESULTS: The cost of treating mild-to-moderate joint bleeds was lower for rFVIIa versus pd-aPCC after 7 days (MX$105,581 vs. MX$132,024), assuming complete bleed resolution. After 48 hours, rFVIIa was associated with an 8% improvement in bleed resolution versus pd-aPCC, resulting in cost savings of MX$16,754. Probabilistic sensitivity analysis indicated that rFVIIa treatment was more cost-effective than pd-aPCC in 67% (at 7 days) and 72% (at 48 hours) of Monte Carlo simulations. CONCLUSION: Accounting for model uncertainty, rFVIIa provided cost savings over pd-aPCC for the Mexican public health care payer in the management of mild-to-moderate joint bleeds in pediatric hemophilia A with inhibitors.

Cost versus utility of aclidinium bromide 400 µg plus formoterol fumarate dihydrate 12 µg compared to aclidinium bromide 400 µg alone in the management of moderate-to-severe COPD.

PURPOSE: Aclidinium-formoterol 400/12 µg is a long-acting muscarinic antagonist (LAMA) and a long-acting ß2-agonist in a fixed-dose combination used in the management of patients with COPD. This study aimed to assess the cost-effectiveness of aclidinium-formoterol 400/12 µg against the long-acting muscarinic antagonist aclidinium bromide 400 µg. MATERIALS AND METHODS: A five-health-state Markov transition model with monthly cycles was developed using MS Excel to simulate patients with moderate-to-severe COPD and their initial lung-function improvement following treatment with aclidinium-formoterol 400/12 µg or aclidinium 400 µg. Health states were based on severity levels defined by Global Initiative for Chronic Obstructive Lung Disease 2010 criteria. The analysis was a head-to-head comparison without step-up therapy, from the NHS Scotland perspective, over a 5-year time horizon. Clinical data on initial lung-function improvement were provided by a pooled analysis of the ACLIFORM and AUGMENT trials. Management, event costs, and utilities were health state-specific. Costs and effects were discounted at an annual rate of 3.5%. The outcome of the analysis was expressed as cost (UK£) per quality-adjusted life-year (QALY) gained. The analysis included one way and probabilistic sensitivity analyses to investigate the impact of parameter uncertainty on model outputs. RESULTS: Aclidinium-formoterol 400/12 µg provided marginally higher costs (£41) and more QALYs (0.014), resulting in an incremental cost-effectiveness ratio of £2,976/QALY. Sensitivity analyses indicated that results were robust to key parameter variations, and the main drivers were: mean baseline forced expiratory volume in 1 second (FEV1), risk of exacerbation, FEV1 improvement from aclidinium-formoterol 400/12 µg, and lung-function decline. The probability of aclidinium-formoterol 400/12 µg being cost-effective (using a willingness-to-pay threshold of £20,000/QALY) versus aclidinium 400 µg was 79%. CONCLUSION: In Scotland, aclidinium-formoterol 400/12 µg can be considered a cost-effective treatment option compared to aclidinium 400 µg alone in patients with moderate-to-severe COPD.
