Medical costs associated with cardiovascular events among high-risk patients with hyperlipidemia

An evaluation of the cost-effectiveness of population genetic screening for familial hypercholesterolemia in US patients

BACKGROUND AND AIMS

Familial hypercholesterolemia is an underdiagnosed genetic metabolic condition limiting the clearance of low-density lipoprotein cholesterol and increasing lifetime risk of cardiovascular disease. Population genetic screening in unselected individuals could quickly identify cases of familial hypercholesterolemia and enable early prevention, but the economic impact of widespread screening on patients has not been studied.

METHODS

We assessed the cost-effectiveness of population genetic screening for familial hypercholesterolemia in 20 and 35-year-old adults in the United States from the perspective of patients. We developed a decision tree Markov hybrid model to examine diagnoses, cardiovascular disease, cardiac events, quality of life, and costs under population genetic screening compared to family-based cascade testing.

RESULTS

While population genetic screening increased diagnoses and reduced incidence of cardiovascular disease, population genetic screening was not cost-effective compared to cascade testing at current levels of willingness to pay. Lower genetic testing costs, combined screening with other genetic conditions, and support to maintain lipid-lowering therapy use over time could improve the cost-effectiveness of population genetic screening.

CONCLUSIONS

Future research is needed to examine how cost-sharing strategies may affect the cost-effectiveness of screening to patients and how families and providers experience the clinical and economic outcomes of population screening.

Cost-effectiveness of incentives for physical activity in coronary heart disease in Germany: pre-trial health economic model of a complex intervention following the new MRC framework

Objectives

The German Incentives for Physical Activity in Cardiac Patients trial is a three-arm, randomised controlled trial for secondary prevention of coronary heart disease (CHD). Guidance for developing complex interventions recommends pre-trial health economic modelling. The aim of this study is to model the long-term cost-effectiveness of the incentive-based physical activity interventions in a population with CHD.

Methods

A decision-analytical Markov model was developed from a health services provider perspective, following a cohort aged 65 years with a previous myocardial infarction for 25 years. Monetary and social incentives were compared relative to no incentive. Intervention effects associated with physical activity were used to determine the costs, quality-adjusted life-years (QALYs) gained, incremental cost-effectiveness and cost-utility ratios. The probability of cost-effectiveness was calculated through sensitivity analyses.

Results

The incremental QALYs gained from the monetary and social incentives, relative to control, were respectively estimated at 0.01 (95% CI 0.00 to 0.01) and 0.04 (95% CI 0.02 to 0.05). Implementation of the monetary and social incentive interventions increased the costs by €874 (95% CI €744 to €1047) and €909 (95% CI €537 to €1625). Incremental cost-utility ratios were €25 912 (95% CI €15 056 to €50 210) and €118 958 (95% CI €82 930 to €196 121) per QALY gained for the social and monetary incentive intervention, respectively. With a willingness-to-pay threshold set at €43 000/QALY, equivalent to the per-capita gross domestic product in Germany, the probability that the social and monetary incentive intervention would be seen as cost-effective was 95% and 0%, respectively.

Conclusions

Exercise-based secondary prevention using inventive schemes may offer a cost-effective strategy to reduce the burden of CHD.

Estimating the Cardiovascular Disease Risk Reduction of a Quality Improvement Initiative in Primary Care: Findings from EvidenceNOW

BACKGROUND

This study estimates reductions in 10-year atherosclerotic cardiovascular disease (ASCVD) risk associated with EvidenceNOW, a multi-state initiative that sought to improve cardiovascular preventive care in the form of (A)spirin prescribing for high-risk patients, (B)lood pressure control for people with hypertension, (C)holesterol management, and (S)moking screening and cessation counseling (ABCS) among small primary care practices by providing supportive interventions such as practice facilitation.

DESIGN

We conducted an analytic modeling study that combined (1) data from 1,278 EvidenceNOW practices collected 2015 to 2017; (2) patient-level information of individuals ages 40 to 79 years who participated in the 2015 to 2016 National Health and Nutrition Examination Survey (n = 1,295); and (3) 10-year ASCVD risk prediction equations.

MEASURES

The primary outcome measure was 10-year ASCVD risk.

RESULTS

EvidenceNOW practices cared for an estimated 4 million patients ages 40 to 79 who might benefit from ABCS interventions. The average 10-year ASCVD risk of these patients before intervention was 10.11%. Improvements in ABCS due to EvidenceNOW reduced their 10-year ASCVD risk to 10.03% (absolute risk reduction: -0.08, P ≤ .001). This risk reduction would prevent 3,169 ASCVD events over 10 years and avoid $150 million in 90-day direct medical costs.

CONCLUSION

Small preventive care improvements and associated reductions in absolute ASCVD risk levels can lead to meaningful life-saving benefits at the population level.

Return on investment of self-measured blood pressure is associated with its use in preventing false diagnoses, not monitoring hypertension

Previous research indicates that patient self-measured blood pressure (SMBP) is a cost-effective strategy for improving hypertension (HTN) diagnosis and control. However, it is unknown which specific uses of SMBP produce the most value. Our goal is to estimate, from an insurance perspective, the return-on-investment (ROI) and net present value associated with coverage of SMBP devices when used (a) only to diagnose HTN, (b) only to select and titrate medication, (c) only to monitor HTN treatment, or (d) as a bundle with all three uses combined. We employed national sample of claims data, Framingham risk predictions, and published sensitivity-specificity values of SMBP and clinic blood-pressure measurement to extend a previously-developed local decision-analytic simulation model. We then used the extended model to determine which uses of SMBP produce the most economic value when scaled to the U.S. adult population. We found that coverage of SMBP devices yielded positive ROIs for insurers in the short-run and at lifetime horizon when the three uses of SMBP were considered together. When each use was evaluated separately, positive returns were seen when SMBP was used for diagnosis or for medication selection and titration. However, returns were negative when SMBP was used exclusively to monitor HTN treatment. When scaled to the U.S. population, adoption of SMBP would prevent nearly 16.5 million false positive HTN diagnoses, thereby improving quality of care while saving insurance plans $254 per member. A strong economic case exists for insurers to cover the cost of SMBP devices, but it matters how devices are used.

The Cost-Effectiveness of Palliative Care: Insights from the PAL-HF Trial

BACKGROUND

In a randomized control trial, Palliative Care in Heart Failure (PAL-HF) improved heart failure-related quality of life, though cost-effectiveness remains unknown. The aim of this study was to evaluate the cost-effectiveness of the PAL-HF trial, which provided outpatient palliative care to patients with advanced heart failure.

METHODS AND RESULTS

Outcomes for usual care and PAL-HF strategies were compared using a Markov cohort model over 36 months from a payer perspective. The model parameters were informed by PAL-HF trial data and supplemented with meta-analyses and Medicare administrative data. Outcomes included hospitalization, place of death, Medicare expenditures, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios. Simulated mortality rates were the same for PAL-HF and usual care cohorts, at 89.7% at 36 months. In the base case analysis, the PAL-HF intervention resulted in an incremental gain of 0.03 QALYs and an incremental cost of $964 per patient for an incremental cost-effectiveness ratio of $29,041 per QALY. In 1-way sensitivity analyses, an intervention cost of up to $140 per month is cost effective at $50,000 per QALY. Of 1000 simulations, the PC intervention had a 66.1% probability of being cost effective at a $50,000 willingness-to-pay threshold assuming no decrease in hospitalization. In a scenario analysis, PAL-HF decreased payer spending through reductions in noncardiovascular hospitalizations.

CONCLUSIONS

These results from this single-center trial are encouraging that palliative care for advanced heart failure is an economically attractive intervention. Confirmation of these findings in larger multicenter trials will be an important part of developing the evidence to support more widespread implementation of the PAL-HF palliative care intervention.

Healthcare Cost Implications of Utilizing a Dietary Intervention to Lower LDL Cholesterol: Proof of Concept Actuarial Analysis and Recommendations

PURPOSE OF REVIEW

To determine if subsidizing the cost of a food-based intervention for managing hyperlipidemia could be cost-effective under commercial insurance and/or Medicare coverage scenarios.

RECENT FINDINGS

A large number of patients eligible for pharmaceutical treatment of hyperlipidemia either cannot or will not use lipid lowering drugs, leaving them at increased cardiovascular risk. Lipid levels can be modified by diet, but food has never enjoyed covered benefit status. We evaluated the financial implications of providing insurance coverage for a specifically formulated suite of food products previously documented to yield statistically significant lipid reductions, using multiple product uptake and lipid impact scenarios in both commercially covered and Medicare-covered populations. Even after controlling for multiple confounders, we noted positive payback on subsidizing the cost of lipid-lowering foods under all scenarios. Addressing a root cause of hyperlipidemia by directly encouraging dietary modification provides a cost-effective alternative for cholesterol management, especially for statin intolerant or statin unwilling patients.

Cost-effectiveness of ranibizumab and aflibercept to treat diabetic macular edema from a US perspective: analysis of 2-year Protocol T data

Aims: Protocol T (NCT01627249) was a head-to-head study conducted by the Diabetic Retinopathy Clinical Research Network that compared intravitreal aflibercept, bevacizumab, and ranibizumab for the treatment of diabetic macular edema (DME). A cost-effectiveness analysis accompanying the 1-year data of Protocol T revealed that aflibercept was not cost-effective vs ranibizumab for all patients, but could have been cost-effective in certain patient sub-groups if the 1-year results were extrapolated out to 10 years. The present study evaluated the cost-effectiveness of US Food and Drug Administration-approved anti-vascular endothelial growth factor agents (ranibizumab, aflibercept) for treatment of DME using the 2-year data from Protocol T.Methods: Costs of aflibercept 2.0 mg or ranibizumab 0.3 mg, visual acuity (VA)-related medical costs, and quality-adjusted life-years (QALYs) were simulated for eight VA health states. Treatment, adverse event management, and VA-related healthcare resource costs (2016 US dollars) were based on Medicare reimbursement and published literature. VA-related health utilities were determined using a published algorithm. Patients were stratified by baseline VA: 20/40 or better; 20/50 or worse.Results: Total 2-year costs were higher, and QALYs similar, for aflibercept vs ranibizumab in the full cohort ($44,423 vs $34,529; 1.476 vs 1.466), 20/40 or better VA sub-group ($40,854 vs $31,897; 1.517 vs 1.519), and 20/50 or worse VA sub-group ($48,214 vs $37,246; 1.433 vs 1.412), respectively. Incremental cost-effectiveness ratios in the full cohort and 20/50 or worse VA sub-group were $986,159/QALY and $523,377/QALY, respectively. These decreased to $711,301 and $246,978 when analyses were extrapolated to 10 years.Limitations: Key potential limitations include the fact that VA was the only QALY parameter analyzed and the uncertainty surrounding the role of better- and worse-seeing eye VA in overall functional impairment.Conclusions: This analysis suggests that aflibercept is not cost-effective vs ranibizumab for patients with DME, regardless of baseline vision.

Cost-effectiveness of Evolocumab Therapy for Reducing Cardiovascular Events in Patients With Atherosclerotic Cardiovascular Disease

Importance

The proprotein convertase subtilisin/kexin type 9 inhibitor evolocumab has been demonstrated to reduce the composite of myocardial infarction, stroke, or cardiovascular death in patients with established atherosclerotic cardiovascular disease. To our knowledge, long-term cost-effectiveness of this therapy has not been evaluated using clinical trial efficacy data.

Objective

To evaluate the cost-effectiveness of evolocumab in patients with atherosclerotic cardiovascular disease when added to standard background therapy.

Design, Setting, and Participants

A Markov cohort state-transition model was used, integrating US population-specific demographics, risk factors, background therapy, and event rates along with trial-based event risk reduction. Costs, including price of drug, utilities, and transitional probabilities, were included from published sources.

Exposures

Addition of evolocumab to standard background therapy including statins.

Main Outcomes and Measures

Cardiovascular events including myocardial infarction, ischemic stroke and cardiovascular death, quality-adjusted life-year (QALY), incremental cost-effectiveness ratio (ICER), and net value-based price.

Results

In the base case, using US clinical practice patients with atherosclerotic cardiovascular disease with low-density lipoprotein cholesterol levels of at least 70 mg/dL (to convert to millimoles per liter, multiply by 0.0259) and an annual events rate of 6.4 per 100 patient-years, evolocumab was associated with increased cost and improved QALY: incremental cost, $105 398; incremental QALY, 0.39, with an ICER of $268 637 per QALY gained ($165 689 with discounted price of $10 311 based on mean rebate of 29% for branded pharmaceuticals). Sensitivity and scenario analyses demonstrated ICERs ranging from $100 193 to $488 642 per QALY, with ICER of $413 579 per QALY for trial patient characteristics and event rate of 4.2 per 100 patient-years ($270 192 with discounted price of $10 311) and $483 800 if no cardiovascular mortality reduction emerges. Evolocumab treatment exceeded $150 000 per QALY in most scenarios but would meet this threshold at an annual net price of $9669 ($6780 for the trial participants) or with the discounted net price of $10 311 in patients with low-density lipoprotein cholesterol levels of at least 80 mg/dL.

Conclusions and Relevance

At its current list price of $14 523, the addition of evolocumab to standard background therapy in patients with atherosclerotic cardiovascular disease exceeds generally accepted cost-effectiveness thresholds. To achieve an ICER of $150 000 per QALY, the annual net price would need to be substantially lower ($9669 for US clinical practice and $6780 for trial participants), or a higher-risk population would need to be treated.

Updated Cost-effectiveness Assessments of PCSK9 Inhibitors From the Perspectives of the Health System and Private Payers: Insights Derived From the FOURIER Trial

Importance

Preliminary cost-effectiveness analyses of proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) were based on benefits estimated from reductions in low-density lipoprotein cholesterol that occurred in PCSK9i trials with variable results. The recent Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk (FOURIER) trial provides better information about the effectiveness of the drug.

Objective

To use the trial results to determine the cost-effectiveness of a PCSK9i and statin treatment strategy compared with a statin alone strategy.

Design, Setting, and Participants

We derived observed rates of events, outcomes, cost of care, and health insurance from existing literature for a theoretical cohort of patients designed to resemble the FOURIER PCSK9i trial population and created a Markov model during the time horizon of a full lifetime.

Main Outcomes and Measures

We evaluated the incremental cost-effectiveness ratio from a health system perspective, and the return on investment from a private payer perspective. For both measures, we assumed an annual PCSK9i drug price of $14 300, with a lapse in US patent protection that would reduce the price by 43% in year 12. Costs were reported in 2016 US dollars.

Results

This study modeled 1000 hypothetical patients with attributes similar to those of the FOURIER trial cohort. At the current price, the incremental cost-effectiveness ratio of statin plus PCSK9i therapy was $337 729 per quality-adjusted life-year. Our probabilistic sensitivity analysis found that a statin plus PCSK9i strategy had a low probability (<1%) of being cost effective at the commonly accepted societal threshold of $100 000 per quality-adjusted life-year. Furthermore, PCSK9i produced a negative return on investment of 86% for private payers. In our threshold analysis, the price of PCSK9i would need to drop 62%, to $5459 per year, to reach $100 000 per quality-adjusted life year.

Conclusions and Relevance

At current prices, the addition of PCSK9i to statin therapy is estimated to provide an additional quality-adjusted life year for $337 729 . Significant discounts are necessary to meet conventional cost-effectiveness standards.

Development and Validation of PREDICT-DM: A New Microsimulation Model to Project and Evaluate Complications and Treatments of Type 2 Diabetes Mellitus

Background: Type 2 diabetes mellitus (T2DM) affects ∼30 million people in the United States and ∼400 million people worldwide, numbers likely to increase due to the rising prevalence of obesity. We sought to design, develop, and validate PREDICT-DM (PRojection and Evaluation of Disease Interventions, Complications, and Treatments-Diabetes Mellitus), a state-transition microsimulation model of T2DM, incorporating recent data. Methods: PREDICT-DM is populated with natural history, risk factor, and outcome data from large-scale cohort studies and randomized clinical trials. The model projects diabetes-relevant outcomes, including cardiovascular and renal disease outcomes, and 5/10-year survival. We assessed the model validity against 62 endpoints from ACCORD (Action to Control Cardiovascular Risk in Diabetes), VADT (Veterans Affairs Diabetes Trial), and Look AHEAD trials via several comparative statistical methods, including mean absolute percentage error (MAPE), Bland-Altman graphs, and Kaplan-Meier curves. Results: For the comparison between simulated and observed outcomes of the intervention/control arms of the trial, the MAPE was 19%/25% (ACCORD), 29%/20% (VADT), and 42%/10% (Look AHEAD). The Bland-Altman's 95% limit of agreement was 0.02 (ACCORD), 0.03 (VADT), and 0.01 (Look AHEAD), and the mean difference (95% confidence interval) for the comparison between PREDICT-DM and trial endpoints was 0.0025 (-0.0018 to 0.0070) for ACCORD, -0.0067 (-0.0137 to 0.0002) for VADT, and -0.0033 (-0.0067 to 0.00002) for Look AHEAD, indicating an adequate model fit to the data. The model-driven Kaplan-Meier curves were similarly close to those previously published. Conclusions: PREDICT-DM can reasonably predict clinical outcomes from ACCORD and other clinical trials of U.S. patients with T2DM. This model may be leveraged to inform clinical strategy questions related to the management and care of T2DM in the United States.

Economic modelling of costs associated with outcomes reported for type 2 diabetes mellitus (T2DM) patients in the CANVAS and EMPA-REG cardiovascular outcomes trials

AIMS

To model direct medical costs associated with reductions in cardiovascular disease (CVD) events in T2DM patients reported in the CANVAS and EMPA-REG trials, which assessed the cardiovascular safety of canagliflozin and empagliflozin, respectively.

MATERIALS AND METHODS

Costs were modeled from a US managed care organization (MCO) perspective for the CVD outcomes included in both trials: three-point major adverse cardiovascular event (MACE) and its components (cardiovascular-related death, nonfatal myocardial infarction, nonfatal stroke), as well as heart failure requiring hospitalization. The rate of CVD events averted (difference between study drug and placebo) was projected to the portion of an MCO T2DM population matching the respective trial's inclusion criteria. A targeted literature search for paid amounts directly associated with each CVD event provided the unit costs, which were applied to the projected number of events averted, to calculate costs avoided per member per year (PMPY). One-way sensitivity analyses were performed on events averted, unit costs, and percentages of trial-applicable patients.

RESULTS

Based on three-point MACE events averted, costs avoided PMPY of $6.17 (range: $1.27-$10.94) for CANVAS and $2.75 ($0.19-$4.83) for EMPA-REG were estimated. Costs avoided for individual components of MACE ranged from $0.77 to $3.84 PMPY for CANVAS and from -$0.97 (additional costs) to $1.54 for EMPA-REG. PMPY costs avoided for heart failure were $2.72 for CANVAS and $1.32 for EMPA-REG.

LIMITATIONS AND CONCLUSIONS

Models assumed independent, non-recurrent outcomes and were restricted to medical costs directly associated with the trial-reported events. The reductions in CVD events in T2DM patients reported for both CANVAS and EMPA-REG project to a positive cost avoidance for these events in an MCO population. The analysis did not include an assessment of the impact on total cost, as the costs associated with adverse events, drug utilization or other clinical outcomes were not examined.

Payer and Pharmaceutical Manufacturer Considerations for Outcomes-Based Agreements in the United States

BACKGROUND

Considerable interest exists among health care payers and pharmaceutical manufacturers in designing outcomes-based agreements (OBAs) for medications for which evidence on real-world effectiveness is limited at product launch.

OBJECTIVES

To build hypothetical OBA models in which both payer and manufacturer can benefit.

METHODS

Models were developed for a hypothetical hypercholesterolemia OBA, in which the OBA was assumed to increase market access for a newly marketed medication. Fixed inputs were drug and outcome event costs from the literature over a 1-year OBA period. Model estimates were developed using a range of inputs for medication effectiveness, medical cost offsets, and the treated population size. Positive or negative feedback to the manufacturer was incorporated on the basis of expectations of drug performance through changes in the reimbursement level. Model simulations demonstrated that parameters had the greatest impact on payer cost and manufacturer reimbursement.

RESULTS

Models suggested that changes in the size of the population treated and drug effectiveness had the largest influence on reimbursement and costs. Despite sharing risk for potential product underperformance, manufacturer reimbursement increased relative to having no OBA, if the OBA improved market access for the new product. Although reduction in medical costs did not fully offset the cost of the medication, the payer could still save on net costs per patient relative to having no OBA by tying reimbursement to drug effectiveness.

CONCLUSIONS

Pharmaceutical manufacturers and health care payers have demonstrated interest in OBAs, and under a certain set of assumptions both may benefit.

Real-world use of PCSK-9 inhibitors by early adopters: cardiovascular risk factors, statin co-treatment, and short-term adherence in routine clinical practice

Background

Inconsistency of real-world medication use with labeled indications may affect cost and clinical value of pharmacotherapy. PCSK-9 inhibitors are labeled in the US for use with statins to reduce low-density lipoprotein cholesterol in patients with atherosclerotic cardiovascular disease (ASCVD) or familial hypercholesterolemia (FH).

Objective

To assess consistency with labeled indications and treatment persistency for early (first 5 post-launch months) adopters of PCSK-9 inhibitor pharmacotherapy.

Methods

Retrospective analysis of commercially insured cohorts derived from the Truven Health MarketScan^® database was performed. Subjects were aged 18–64 years, initiated PCSK-9 inhibitor or highest-intensity statin (rosuvastatin 40 mg/day or atorvastatin 80 mg/day) pharmacotherapy from August to December 2015, and were enrolled throughout 2015 and during separate baseline (pre-treatment) periods of 6 and 18 months. Baseline ASCVD, FH, and ASCVD events (myocardial infarction, transient ischemic attack, and cerebrovascular occlusion) were measured. Persistency was measured through December 2015 for subcohorts of patients initiating treatment from August to September 2015.

Results

Baseline disease rates were higher for patients treated with PCSK-9 inhibitors (n=390) compared with highest-intensity statins (n=26,306): ASCVD (68.5% vs 33.4%, respectively); FH (39.7% vs 15.5%); both P<0.001. In 18 months pre-treatment, 35.6% of PCSK-9 inhibitor-treated patients had ≥1 ASCVD event, and 87.9% had a labeled indication. Rates of 60-day nonpersistency for PCSK-9 inhibitors and highest-intensity statins were 33.3% and 39.8%, respectively (P=0.207). During PCSK-9 inhibitor pharmacotherapy, 33.8% of patients had evidence of statin supply and, of those initiating treatment from August to September, 40.9% filled ≥1 statin prescription. Of those with sustained pre-treatment statin use, 34.8% had no statin supply during PCSK-9 inhibitor pharmacotherapy.

Conclusion

Among early-adopting PCSK-9 inhibitor-treated patients, the off-label diagnosis rate was 12%; a majority lacked statin co-treatment; and one third filled prescriptions for ≤60 days. Inconsistency with labeled uses may reflect prescriber/patient decisions, health-insurance coverage determinations, or statin intolerance not reported on claims.

Estimated burden of cardiovascular disease and value-based price range for evolocumab in a high-risk, secondary-prevention population in the US payer context

AIM

To estimate real-world cardiovascular disease (CVD) burden and value-based price range of evolocumab for a US-context, high-risk, secondary-prevention population.

MATERIALS AND METHODS

Burden of CVD was assessed using the UK-based Clinical Practice Research Datalink (CPRD) in order to capture complete CV burden including CV mortality. Patients on standard of care (SOC; high-intensity statins) in CPRD were selected based on eligibility criteria of FOURIER, a phase 3 CV outcomes trial of evolocumab, and categorized into four cohorts: high-risk prevalent atherosclerotic CVD (ASCVD) cohort (n = 1448), acute coronary syndrome (ACS) (n = 602), ischemic stroke (IS) (n = 151), and heart failure (HF) (n = 291) incident cohorts. The value-based price range for evolocumab was assessed using a previously published economic model. The model incorporated CPRD CV event rates and considered CV event reduction rate ratios per 1 mmol/L reduction in low-density lipoprotein-cholesterol (LDL-C) from a meta-analysis of statin trials by the Cholesterol Treatment Trialists Collaboration (CTTC), i.e. CTTC relationship.

RESULTS

Multiple-event rates of composite CV events (ACS, IS, or coronary revascularization) per 100 patient-years were 12.3 for the high-risk prevalent ASCVD cohort, and 25.7, 13.3, and 23.3, respectively, for incident ACS, IS, and HF cohorts. Approximately one-half (42%) of the high-risk ASCVD patients with a new CV event during follow-up had a subsequent CV event. Combining these real-world event rates and the CTTC relationship in the economic model, the value-based price range (credible interval) under a willingness-to-pay threshold of $150,000/quality-adjusted life-year gained for evolocumab was $11,990 ($9,341-$14,833) to $16,856 ($12,903-$20,678) in ASCVD patients with baseline LDL-C levels ≥70 mg/dL and ≥100 mg/dL, respectively.

CONCLUSION

Real-world CVD burden is substantial. Using the observed CVD burden in CPRD and the CTTC relationship, the cost-effectiveness analysis showed that, accounting for uncertainties, the expected value-based price for evolocumab is higher than its current annual cost, as long as the payer discount off list price is greater than 20%.

The budget impact of using enteric-coated aspirin 325 mg + immediate-release omeprazole 40 mg to prevent recurrent cardiovascular events

OBJECTIVE

Aspirin (acetylsalicylic acid; ASA) is commonly used for secondary prevention of cardiovascular (CV) events, but may be associated with gastrointestinal (GI) adverse events, which can reduce adherence. Use of ASA co-therapy with proton pump inhibitors in patients at risk may be suboptimal. PA32540 (Yosprala™) is a coordinated-delivery tablet combining EC-ASA 325 mg and immediate-release omeprazole 40 mg. The objective of this flexible budget impact model was to project the financial consequences of introducing PA32540 325 mg/40 mg to prevent recurrent CV events, while reducing ASA-associated GI events in US adults.

METHODS

A Markov Model was employed to estimate health state transitions associated with ASA 75-325 mg, ASA 75-325 mg + generic delayed-release omeprazole 40 mg, PA32540, or clopidogrel 75 mg to prevent recurrent CV events. Health states included ulcers, GI bleeding, CV events, and death. Model inputs included demographics, treatment dosages, treatment costs, adverse GI and CV events, and premature death. Data from peer-reviewed literature and censuses enabled appropriate allocation of CV and GI disease prevalence and mortality. The PA32540 non-adherence rate was conservatively set at 20%. PA32540 market share was set to 50%.

RESULTS

The model projected annual savings of $81.0 million to $190.9 million within 1-5 years after PA32540 introduction to the plan, which included 134,558 members at risk for recurrent CV events. These values translate into savings of $602 (year 5) to $1,419 (year 1) per patient per year, and $81 (year 5) to $191 (year 1) per member per year. These values were robust to variations in parameters under a deterministic sensitivity analysis.

CONCLUSION

PA32540 use to prevent recurrent CV events was associated with cost reductions in each year examined with the model. From a health plan perspective, PA32540 is likely to have a net overall effect, resulting in significant cost savings.

Cost-effectiveness of Aflibercept, Bevacizumab, and Ranibizumab for Diabetic Macular Edema Treatment: Analysis From the Diabetic Retinopathy Clinical Research Network Comparative Effectiveness Trial

IMPORTANCE

Anti-vascular endothelial growth factor (VEGF) medicines have revolutionized diabetic macular edema (DME) treatment. A recent randomized clinical trial comparing anti-VEGF agents for patients with decreased vision from DME found that at 1 year aflibercept (2.0 mg) achieved better visual outcomes than repackaged (compounded) bevacizumab (1.25 mg) or ranibizumab (0.3 mg); the worse the starting vision, the greater the treatment benefit with aflibercept. However, aflibercept and ranibizumab, respectively, are approximately 31 and 20 times more expensive than bevacizumab.

OBJECTIVE

To examine the incremental cost-effectiveness ratios (ICERs) of aflibercept, bevacizumab, and ranibizumab for the treatment of DME.

DESIGN, SETTING, AND PARTICIPANTS

Post hoc analysis of efficacy, safety, and resource utilization data at 1-year follow-up from the Diabetic Retinopathy Clinical Research Network Comparative Effectiveness Trial. Patients were enrolled from August 22, 2012, through August 28, 2013, and analysis was performed from August 21, 2014, through November 7, 2015.

MAIN OUTCOMES AND MEASURES

The ICERs for all trial participants and subgroups with baseline vision of approximate Snellen equivalent 20/32 to 20/40 (better vision) and baseline vision of approximate Snellen equivalent 20/50 or worse (worse vision). One-year trial data were used to calculate cost-effectiveness for 1 year for the 3 anti-VEGF agents; mathematical modeling was then used to project 10-year cost-effectiveness results.

RESULTS

The study included 624 participants (mean [SD] age, 60.6 [10.5] years; 45.7% female; 65.5% white), 209 in the aflibercept group, 207 in the bevacizumab group, and 208 in the ranibizumab group. For all participants, during 1 year, the ICERs of aflibercept and ranibizumab compared with bevacizumab were $1 110 000 per quality-adjusted life-year (QALY) and $1 730 000 per QALY, respectively. During 10 years, they were $349 000 per QALY and $603 000 per QALY, respectively. Compared with ranibizumab, aflibercept's ICER was $648 000 per QALY at 1 year and $203 000 per QALY at 10 years. For the subgroup with worse baseline vision, the 10-year ICERs of aflibercept and ranibizumab compared with bevacizumab were $287 000 per QALY and $817 000 per QALY, respectively. In eyes with decreased vision from DME, treatment costs of aflibercept and ranibizumab would need to decrease by 69% and 80%, respectively, to reach a cost-effectiveness threshold of $100 000 per QALY compared with bevacizumab during a 10-year horizon; for the subgroup with worse baseline vision, the costs would need to decrease by 62% and 84%, respectively.

CONCLUSIONS AND RELEVANCE

Aflibercept (2.0 mg) and ranibizumab (0.3 mg) are not cost-effective relative to bevacizumab for treatment of DME unless their prices decrease substantially. These results highlight the challenges that physicians, patients, and policymakers face when safety and efficacy results are at odds with cost-effectiveness results.

Cost-Effectiveness of LDL-C Lowering With Evolocumab in Patients With High Cardiovascular Risk in the United States

Randomized trials have shown marked reductions in low‐density lipoprotein cholesterol (LDL‐C), a risk factor for cardiovascular disease (CVD), when evolocumab is administered. We hypothesized that evolocumab added to standard of care (SOC) vs SOC alone is cost‐effective in the treatment of patients with heterozygous familial hypercholesterolemia (HeFH) or atherosclerotic CVD (ASCVD) with or without statin intolerance and LDL‐C >100 mg/dL. Using a Markov cohort state transition model, primary and recurrent CVD event rates were predicted considering population‐specific trial‐based mean risk factors and calibrated against observed rates in the real world. The LDL‐C–lowering effect from population‐specific phase 3 randomized studies for evolocumab was used together with estimated LDL‐C–lowering effect on CVD event rates per 38.67‐mg/dL LDL‐C lowering from a statin‐trial meta‐analysis. Costs and utilities were included from published sources. Evolocumab treatment was associated with both increased cost and improved quality‐adjusted life‐years (QALY): HeFH (incremental cost: US$153 289, incremental QALY: 2.02, incremental cost‐effectiveness ratio: US$75 863/QALY); ASCVD (US$158 307, 1.12, US$141 699/QALY); and ASCVD with statin intolerance (US$136 903, 1.36, US$100 309/QALY). Evolocumab met both the American College of Cardiology/American Heart Association (ACC/AHA) and World Health Organization (WHO) thresholds in each population evaluated. Sensitivity and scenario analyses confirmed that model results were robust to changes in model parameters. Among patients with HeFH and ASCVD with or without statin intolerance, evolocumab added to SOC may provide a cost‐effective treatment option for lowering LDL‐C using ACC/AHA intermediate/high value and WHO cost‐effectiveness thresholds. More definitive information on the clinical and economic value of evolocumab will be available from the forthcoming CVD outcomes study.

National Economic Burden Associated with Management of Periodontitis in Malaysia

Objectives. The aim of this study is to estimate the economic burden associated with the management of periodontitis in Malaysia from the societal perspective. Methods. We estimated the economic burden of periodontitis by combining the disease prevalence with its treatment costs. We estimated treatment costs (with 2012 value of Malaysian Ringgit) using the cost-of-illness approach and included both direct and indirect costs. We used the National Oral Health Survey for Adults (2010) data to estimate the prevalence of periodontitis and 2010 national census data to estimate the adult population at risk for periodontitis. Results. The economic burden of managing all cases of periodontitis at the national level from the societal perspective was approximately MYR 32.5 billion, accounting for 3.83% of the 2012 Gross Domestic Product of the country. It would cost the nation MYR 18.3 billion to treat patients with moderate periodontitis and MYR 13.7 billion to treat patients with severe periodontitis. Conclusion. The economic burden of periodontitis in Malaysia is substantial and comparable with that of other chronic diseases in the country. This is attributable to its high prevalence and high cost of treatment. Judicious application of promotive, preventive, and curative approaches to periodontitis management is decidedly warranted.
