Estimated cost of VEGFR TKI associated adverse events in metastatic renal cell carcinoma patients

IntroductionThe majority of metastatic renal cell carcinoma (mRCC) patients receive one or more VEGFR TKI agents, alone or in combination with an immune-oncology (IO) agent or an mTOR inhibitor. To date, the cost of adverse events (AEs) common to VEGFR TKIs has not been quantified. This study estimated the potential impact of differences in VEGFR TKI AE profiles on treatment cost efficiency in the relapsed/refractory (R/R) setting.MethodsPatients with documented mRCC who were treated with VEGFR TKI therapies between Jan 2015 and Mar 2021 were identified using EMR. ICD-10 diagnosis codes were used to identify the first occurrence of each class effect AE. Patients were matched to 3rd party insurance claims, and costs associated to TKI AEs within 90 days of index event were captured. Average per patient AE cost data was calculated and applied to published incidence data to estimate regimen-specific AE total cost burden within a hypothetical commercial plan for mRCC patients undergoing treatment in the R/R setting.ResultsThe highest total cost for AE management was attributed to lenvatinib and everolimus use at $13,303, followed closely by sunitinib at $13,092. Tivozanib treatment was associated with the lowest total cost of AE management at $7,523, driven by the relatively lower incidence of certain high-cost AEs.ConclusionsThe estimated costs of managing VEGFR TKI class-effect AEs were lowest with tivozanib, and highest with lenvatinib and everolimus, indicating potentially differential healthcare resource burden by TKI regimen. The use of tivozanib in the 3 L + mRCC setting suggests potential costs offsets when compared to other TKI regimens.

One-year budget impact of InTandem™: a novel neurorehabilitation system for individuals with chronic stroke walking impairment.

Aim: Chronic stroke walking impairment is associated with high healthcare resource utilization (HCRU) costs. InTandem™ is a neurorehabilitation system that autonomously delivers a rhythmic auditory stimulation (RAS)-based intervention for the at-home rehabilitation of walking impairment in adults in the chronic phase of stroke recovery. This study was conducted to estimate the budget impact of InTandem in comparison with currently available intervention strategies for improvement of gait/ambulation in individuals with chronic stroke walking impairment. Methods & materials: A budget impact analysis (BIA) for InTandem was conducted based on a 1-million-member US third-party payer perspective over a 1-year time horizon. Key inputs for the budget impact model were: costs for each intervention strategy (InTandem, physical therapy, self-directed walking and no treatment), HCRU costs for persons with chronic stroke and anticipated HCRU cost offsets due to improvements in gait/ambulatory status as measured by self-selected comfortable walking speed (based on functional ability). In addition to the reference case analysis, a sensitivity analysis was conducted. Results: Based on the reference case, introduction of InTandem was projected to result in overall cost savings of $439,954 in one year. Reduction of HCRU costs (-$2,411,778) resulting from improved walking speeds with InTandem offset an increase in intervention costs (+$1,971,824). Demonstrations of cost savings associated with InTandem were robust and were consistently evident in nearly all scenarios evaluated in the sensitivity analysis (e.g., with increased/decreased patient shares, increased HCRU costor increased InTandem rental duration). Conclusion: The InTandem system is demonstrated to improve walking and ambulation in adults in the chronic phase of stroke recovery after a five-week intervention period. The BIA predicts that introduction of InTandem will be associated with overall cost savings to the payer.

The impact of capping health system cost savings on the projected cost-effectiveness of etranacogene dezaparvovec compared with factor IX prophylaxis for the treatment of hemophilia B.

This viewpoint discusses cost-effectiveness estimates for EtranaDez, a gene therapy for hemophilia B, using the Institute for Clinical and Economic Review's (ICER) framework for single and short-term therapies (SSTs). EtranaDez offers long-term benefits from a single administration, in contrast to the high costs and frequent dosing required by current factor IX prophylaxis. However, the projected gains in health from EtranaDez are small relative to the cost implications of the therapy, and consequently, how the cost offsets associated with EtranaDez are counted has a substantial impact on assessing its cost-effectiveness. Strategies for assessing cost offsets used in the ICER SST framework include a 50/50 cost-sharing model between the health care system and the manufacturer and a cap of $150,000 annually on health care cost offsets. Results from the standard full cost-offset analysis as reported by ICER depicted EtranaDez as a dominant therapy with substantial cost savings compared with factor IX prophylaxis. However, while considering the ICER SST framework, particularly the $150,000 annual cap scenario, the cost-effectiveness was significantly reduced. The incremental cost-effectiveness ratio varied notably between these scenarios, challenging the conventional perception of value of gene therapy in health care. These cost-sharing scenarios highlight the potential of the ICER SST framework to help curtail inefficient health care spending. In cases in which the cost of existing treatment is exceedingly high, the application of such frameworks would improve efficiency in resource allocation, fostering a balance between incentives for innovation and economic sustainability in managed care systems.

Benefits of dapagliflozin in chronic kidney disease for US commercial payers: A cost-offset analysis.

One in 7 adults have chronic kidney disease (CKD), which is associated with high morbidity and mortality and substantial health care costs, especially in more advanced disease. Our data from a US commercial payer show rising per-member-per-year costs for renal and cardiac complications associated with CKD. To predict the clinical and economic impact of treatment with or without dapagliflozin from the perspective of a US commercial payer using a cost-offset model (COM). The COM used real-world cost and member count data from a US employer-sponsored commercial payer and results of the double-blind, randomized, phase 3 Dapagliflozin and Prevention of Adverse Outcomes in CKD clinical trial (NCT03036150) to predict the incidence of clinical events, including a greater than or equal to 50% decline in estimated glomerular filtration rate (eGFR), end-stage kidney disease, and hospitalization for heart failure, and their associated costs over a 3-year period. The COM compared a hypothetical scenario of the experience with or without dapagliflozin in members with CKD stages 2-4, aged younger than 65 years. In the simulated populations of 130 members, the COM projected 9 events of a greater than or equal to 50% decline in estimated glomerular filtration rate for the experience with dapagliflozin vs 15 events for the experience without dapagliflozin (6 fewer events; number needed to treat [NNT] = 20, amounting to estimated cumulative cost offsets of $0.57 million [M] over a 3-year period). The COM projected similar results for end-stage kidney disease (8 events with dapagliflozin vs 14 events without dapagliflozin; NNT = 24, amounting to $1.92 M in cumulative cost offsets) and for hospitalization for heart failure (13 events with dapagliflozin vs 33 events without dapagliflozin; NNT = 7, amounting to $0.79 M in cumulative cost offsets). These projections translated to total mean, cumulative cost offsets of $3.89 M for all clinical events evaluated over the 3-year period (36.6% reduction with dapagliflozin vs without dapagliflozin), and net mean, cumulative cost offsets of $2.58 M over the 3-year period (24.2% reduction with dapagliflozin vs without dapagliflozin) after factoring in a discounted wholesale acquisition cost for dapagliflozin expenditure ($1.31 M over 3 years). Thus, the net mean, cumulative cost offsets were $19,843 per member over 3 years, representing a 197% return on investment for dapagliflozin expenditure. Results of our COM suggest that dapagliflozin can reduce clinical events and their associated costs over a 3-year period when compared with a scenario without dapagliflozin. Cost offsets increased with each year, indicating that US commercial payers can substantially reduce costs associated with CKD morbidity and mortality.

Health and Economic Outcomes of Pembrolizumab in the Treatment of Metastatic Non-small Cell Lung Cancer (mNSCLC) and Melanoma in Italy.

In Italy, the management of metastatic non-small cell lung cancer and melanoma leads to significant healthcare challenges, necessitating cost-effective treatment strategies and offering valuable insights for healthcare policymakers and stakeholders. This study was designed to assess the costs, quality-adjusted life-years (QALYs) and disability-adjusted life-years (DALYs) associated with the health and economic outcomes of (1) pembrolizumab-combined chemotherapy administered as a first-line treatment for metastatic non-squamous and squamous non-small cell lung cancer (NSCLC) where the tumour presents with a programmed death-ligand 1 expression level <50% and of (2) adjuvant pembrolizumab treatment for stage III melanoma. Three cost-effectiveness models developed by MSD were investigated for each treatment indication. A unique model was built to assess the overall effect of pembrolizumab versus chemotherapy or watchful waiting in patients with lung cancer or melanoma, respectively. Theoretical cohorts of patients with metastatic squamous and non-squamous NSCLC were followed over time using a partitioned survival model with weekly cycles. A weekly cycle Markov model was employed for melanoma. The analysis was conducted from the Italian National Health Service perspective, considering a time horizon of 40 years (lifetime). A single closed cohort of treatable patients was followed over time for each indication (4000, 7000 and 900 for NSCLC squamous, non-squamous and melanoma, respectively). The costs evaluated included those for adverse drug events, non-drug disease management, subsequent treatment and terminal care. Drug acquisition and administration costs were excluded. For each treatment indication assessed, pembrolizumab produced downstream direct cost offsets (- €122,498,568, -€133,369,076 and -€32,993,242 for NSCLC squamous, non-squamous and melanoma indications, respectively), increased quality of life (+2088, +5317 and +2307 QALYs for NSCLC squamous, non-squamous and melanoma indications, respectively) and reduced disability (-2658, -7202 and -3029 DALYs for NSCLC squamous, non-squamous and melanoma indications, respectively). Across indications, the total cost offsets of pembrolizumab were -€288,860,885, with 9712 QALYs gained and 12,889 DALYs avoided. The analysis demonstrated that, compared with chemotherapy, pembrolizumab is more cost effective in Italy as a first-line treatment in patients with metastatic squamous or non-squamous NSCLC and, if compared with watchful waiting, as adjuvant treatment in patients with stage III melanoma. The present analysis suggested that pembrolizumab use could lead to important health benefits for patients while offsetting a portion of cancer care costs.

Implications of treatment duration and frequency for value and cost-effective price of Alzheimer treatments.

Disease-modifying Alzheimer treatments are becoming available. The value of the treatments will be attenuated by their complexity of delivery and monitoring, creating additional medical cost and caregiver burden. To estimate net treatment value using different assumptions for treatment duration and intensity. We estimated the lifetime value of hypothetical treatments that reduce disease progression by 30% from a payer perspective, which considers cost offsets, i.e., reduced medical and formal social care costs, and quality-adjusted life-year gains, and a societal perspective, which adds reduction in caregiver burden. Estimates for gross value of the treatment were based on a prior publication, medical cost on Medicare payment rates, and caregiver time use on a survey of 21 clinics. We analyzed 5 hypothetical treatment scenarios: treatment until progression to moderate dementia with (1) biweekly and (2) 4-weekly infusions, and time-limited infusions every 4 weeks for (3) 72, (4) 52, and (5) 24 weeks. Treatment until progression to moderate dementia would take 5.7 years and generate gross value of $20,734 in direct cost offsets, $83,761 from a payer and $87,749 from a societal perspective, respectively. Added medical cost and caregiver burden for the 5 scenarios would be $44,179, $24,875, $21,632, $20,416, and $14,350, respectively. The maximum value-based price per year would be $7,687, $11,088, $47,708, $67,273, and $158,954. Assuming identical efficacy and safety, the net value generation of time-limited treatment is projected to be larger than that of chronic treatment. Such determination of net lifetime value can be useful to determine value-based prices for different treatment types.

Cost Offset of Dapagliflozin in the US Medicare Population with Cardio-Kidney Metabolic Syndrome.

Cardiovascular-kidney-metabolic (CKM) syndrome is highly prevalent in the US Medicare population and is projected to increase further. Sodium-glucose co-transporter2 inhibitors have indications in chronic kidney disease (CKD), heart failure (HF), and type2 diabetes (T2D), providing protective efficacy across conditions within CKM syndrome. The objective of this study was to develop a model to extrapolate key outcomes observed in pivotal clinical trials to the US Medicare population, and to assess the potential direct cost offsets associated with dapagliflozin therapy. All US 2022 Medicare beneficiaries (≥ 65years of age) eligible to receive dapagliflozin were estimated according to drug label indication and Medicare enrollment and claims data. Incidence of key outcomes from the dapagliflozin clinical program were modelled over a 4-year time horizon based on patient-level data with CKD, HF, and T2D. Published cost data of relevant clinical outcomes were used to calculate direct medical care cost-offset associated with treatment with dapagliflozin. In a population of 13.1million patients with CKM syndrome, treatment with dapagliflozin in addition to historical standard of care (hSoC) versus hSoC alone led to fewer incidents of HF-related events (hospitalization for HF, 613,545; urgent HF visit, 98,896), renal events (kidney failure, 285,041; ≥ 50% sustained decline in kidney function, 375,137), and 450,355fewer deaths (of which 225,346 and 13,206 incidences of cardiovascular and renal death were avoided). In total this led to medical care cost offsets of $99.3billion versus treatment with hSoC only (dapagliflozin plus hSoC, $310.3billion; hSoC, $211.0billion). By extrapolating data from trials across multiple indications within CKM syndrome, this broader perspective shows that considerable medical care cost offsets may result through attenuated incidence of clinical events in CKD, T2D, and HF populations if treated with dapagliflozin in addition to hSoC over a 4-year time horizon.

Cost-effectiveness of add-on empagliflozin versus standard of care in management of CKD in Malaysia, Thailand and Vietnam – findings from a modelling study assessing an EMPA-KIDNEY eligible population, using CKD progression model

Background and objectives Nearly one in ten individuals in South-East Asia are estimated to be affected by chronic kidney disease (CKD). The burden of end-stage kidney disease is significant and can be heavy on the healthcare system. The recent EMPA-KIDNEY trial demonstrated a significant reduction in the risk of kidney disease progression or cardiovascular death in patients with CKD with a broad range of kidney function using add-on empagliflozin versus standard of care (SoC) alone. The objective of this study was to estimate the economic benefit of empagliflozin for patients with CKD in Malaysia, Thailand and Vietnam. Methods An individual patient level simulation model with an annual cycle that estimates the progression of kidney function and associated risk-factors was employed. Local costs and mortality rates were estimated from a wide range of published literature. A healthcare perspective was used over a 50-year time horizon. Results The use of add-on empagliflozin versus SoC alone was found to be cost-saving in Malaysia and Thailand and cost-effective (ICER: 77,838,407 Vietnam Dong/QALY vs. a willingness to pay threshold of 96,890,026/QALY) in Vietnam. The bulk of the costs avoided over a lifetime is derived from the prevention or delay of dialysis initiation or kidney transplant – the cost offsets were nearly twice the additional treatment cost. The results were similar in patients with and without diabetes and across broad range of albuminuria. Conclusions The use of add-on empagliflozin in a broad population of patients with CKD is expected to be cost-saving in Malaysia and Thailand and cost-effective in Vietnam and will help alleviate the increasing burden of CKD in the region.

Cause-Specific Health Care Costs Following Hospitalization for Heart Failure and Cost Offset With SGLT2i Therapy

BackgroundLittle is known regarding differences in cause-specific costs between heart failure (HF) with ejection fraction (EF) ≤40% vs >40%, and potential cost implications of sodium glucose co-transporter 2 inhibitor (SGLT2i) therapy. ObjectivesThis study sought to compare cause-specific health care costs following hospitalization for HF with EF ≤40% vs >40% and estimate the cost offset with implementation of SGLT2i therapy. MethodsThis study examined Medicare beneficiaries hospitalized for HF in the Get With The Guidelines–Heart Failure registry from 2016 to 2020. Mean per-patient total (excluding drug costs) and cause-specific costs from discharge through 1-year follow-up were calculated and compared between EF ≤40% vs >40%. Next, risk reductions on total all-cause and HF hospitalizations were estimated in a trial-level meta-analysis of 5 pivotal trials of SGLT2is in HF. Finally, these relative treatment effects were applied to Medicare beneficiaries eligible for SGLT2i therapy to estimate the projected cost offset with implementation of SGLT2i, excluding drug costs. ResultsAmong 146,003 patients, 50,598 (34.7%) had EF ≤40% and 95,405 (65.3%) had EF >40%. Mean total cost through 1 year was $40,557. Total costs were similar between EF groups overall but were higher for EF ≤40% among patients surviving the 1-year follow-up period. Patients with EF >40% had higher costs caused by non-HF and noncardiovascular hospitalizations, and skilled nursing facilities (all P < 0.001). Trial-level meta-analysis of the 5 SGLT2i clinical trials estimated 11% (rate ratio: 0.89; 95% CI: 0.84-0.93; P < 0.001) and 29% (rate ratio: 0.71; 95% CI: 0.66-0.76; P < 0.001) relative reductions in rates of total all-cause and HF hospitalizations, respectively, regardless of EF. Reductions in all-cause and HF hospitalizations were projected to reduce annual costs of readmission by $2,451 to $2,668 per patient with EF ≤40% and $1,439 to $2,410 per patient with EF >40%. ConclusionsIn this large cohort of older U.S. adults hospitalized for HF, cause-specific costs of care differed among patients with EF ≤40% vs >40%. SGLT2i significantly reduced the rate of HF and all-cause hospitalizations irrespective of EF in clinical trials, and implementation of SGLT2i therapy in clinical practice is projected to reduce costs by $1,439 to $2,668 per patient over the 1 year post-discharge, excluding drug costs.

Cost-effectiveness of nivolumab versus surveillance for the adjuvant treatment of patients with urothelial carcinoma who are at high risk of recurrence: a US payer perspective

Aim To evaluate the cost-effectiveness of adjuvant nivolumab compared with surveillance for the treatment of patients with high-risk muscle-invasive urothelial carcinoma (MIUC) after radical resection from a US healthcare payer perspective and to investigate the impact of alternative modeling approaches on the cost-effectiveness results. Material and methods A four-state, semi-Markov model consisting of disease free, local recurrence, distant recurrence, and death health states was developed to investigate the cost-effectiveness of nivolumab compared with surveillance over a 30-year time horizon. The model used data from the randomized CheckMate 274 trial (NCT02632409) and published literature to inform transitions among health states, and inputs on cost, utility, adverse event, and disease management. Scenario analyses were conducted to investigate the impact of model structure and key assumptions on the results. One-way deterministic and probabilistic sensitivity analysis were conducted to investigate the robustness of the results. Results Total expected costs were higher with nivolumab ($162 268) compared with surveillance ($62 965). Nivolumab was associated with improved survival (1.53 life-years gained compared with surveillance) and an incremental gain of 0.94 quality-adjusted life-years (QALYs). Although total treatment costs were higher for nivolumab, cost offsets were observed because of delayed or avoided recurrences and deaths experienced with nivolumab compared with observation. The incremental cost-effectiveness and cost-utility ratios were $64 929/life-year and $105 660/QALY. Limitations At the time of analysis, CheckMate 274 had limited follow-up on disease-free survival and no overall survival data. The limited evidence necessitated assumptions on modeling survival after each type of recurrence. Conclusions Nivolumab is estimated to be a life-extending and cost-effective option for adjuvant treatment of MIUC for patients who are at high risk of recurrence after undergoing radical resection in the United States. Using a threshold of $150,000/QALY, the cost-effectiveness conclusions remained consistent across the scenario and sensitivity analyses conducted.

Costs and benefits of scaling psychosocial interventions during the perinatal period in England: A simulation modelling study

BackgroundGlobally, guidance recommends the integration of mental health into maternal and child healthcare to address common maternal mental health problems during the perinatal period. However, implementing this in the real-world requires substantial resource allocations. ObjectiveThe aim of this study was to estimate the likely costs and consequences linked to scaling the delivery of treatment (in the form of psychosocial interventions) during the perinatal period. DesignSimulation modelling. Setting(s)England. MethodsCosts and consequences were modelled for three scenarios of assumed provision of services, whereby one referred to the projected provision under current government plans, with no additional scaling up of treatment. The other two scenarios referred to additional scaling of treatment: in one scenario, this referred to the provision of treatment by midwives and health visitors trained in the routine enquiry about mental health and delivery of psychosocial interventions; in the other scenario this referred to an expanded provision by primary mental health services. For each scenario and in yearly intervals (covering a ten-year period, 2015 to 2024), unit cots and outcomes were assigned to the activities women were assumed to receive (routine enquiry, assessment, treatment, care coordination). All costs were in 2020 pounds sterling. Data sources for the modelling included: published findings from randomised controlled trials; national unit cost source; national statistics; and expert consultation. ResultsIf the projected treatment gap was to be addressed, an estimated additional 111,154 (50,031) women would be accessing treatment in 2015 (2024). Estimated total costs (including cost offsets) in the scenario of projected provision under current government plans would be £73.5 million in 2015 and £95.2 million in 2024, whilst quality-adjusted life years gained would be 901 and 928 respectively. Addressing the treatment gap through provision by trained midwives and health visitors could mean additional costs of £7.3 million in 2015 but lower costs of £18.4 million in 2024. The additional quality-adjusted life years gained are estimated at 2096 in 2015 and 1418 in 2024. A scenario in which the treatment gap would be met by primary mental health services was likely to be more costly and delivered less health gains. ConclusionsFindings from this modelling study suggest that scaling the integration of mental health care into routinely delivered care for women during the perinatal period might be economically viable.

Italian healthcare resource consumption for patients on hemodialysis treated for chronic kidney disease-associated pruritus (CKD-aP).

Chronic kidney disease-associated pruritus (CKD-aP) affects patients on hemodialysis. This study identified hemodialysis patients presumably affected or not affected by CKD-aP and integrated healthcare costs, from the perspective of the Italian administrative healthcare data. Through cross-linkage of Italian administrative healthcare data collected between 2015 and 2017 (accrual period) in the database of Fondazione ReS (Ricerca e Salute), patients undergoing in-hospital/outpatient hemodialysis were selected. Cohorts with and without CKD-aP were created based on the presence/absence of CKD-aP-related treatment (according to common clinical practice and guidelines) supplies and assessed in terms of CKD-aP-related treatments and mean healthcare costs per capita paid by the Italian National Health Service (INHS). Of 1,239 people on hemodialysis for ≥2 years, CKD-aP affected 218 patients. Patients with CKD-aP were older and with more comorbidities. During the follow-up year, on average, the INHS spent €37,065 per case, €31,286 per control and € 35,988 per non-CKD-aP subject. High-efficiency dialytic therapies performed to people on hemodialysis with CKD-aP largely weighed on the overall mean annual cost. This real-world study identified patients on chronic hemodialysis potentially treated for CKD-aP. Interestingly, high-efficiency dialysis seems the most frequent and expensive choice for the treatment of CKD-aP. The discovery of appropriate and effective treatments for this condition might offer cost offsets.

Budget Impact of RefluxStop™ as a Treatment for Patients with Refractory Gastro-oesophageal Reflux Disease in the United Kingdom.

Background: Gastro-oesophageal reflux disease (GORD) is a common condition associated with heartburn and regurgitation. Standard of care for GORD patients in the UK involves initial treatment with proton pump inhibitors (PPIs) and laparoscopic antireflux surgery in patients unwilling to continue or intolerant of long-term PPI treatment. Recently, RefluxStop™, a novel, implantable medical device, has proven to be an efficacious and cost-effective treatment for patients with GORD. The current analysis aimed to describe the budget impact of introducing RefluxStop™ within National Health Service (NHS) England and Wales. Objectives: To estimate the more immediate, short-term clinical and economic effects of introducing RefluxStop™ as a therapeutic option for patients with GORD treated within NHS England and Wales. Methods: A model adherent to international best practice guidelines was developed to estimate the budget impact of introducing RefluxStop™ over a 5-year time horizon, from an NHS perspective. Two hypothetical scenarios were considered, one without RefluxStop™ (comprising PPI treatment, laparoscopic Nissen fundoplication, and magnetic sphincter augmentation using the LINX® system) and one with RefluxStop™ (adding RefluxStop™ to the aforementioned treatment options). Clinical benefits and costs associated with each intervention were included in the analysis. Results: Over 5 years, introducing RefluxStop™ allowed the avoidance of 347 surgical failures, 39 reoperations, and 239 endoscopic esophageal dilations. The financial impact of introducing RefluxStop™ was £3 029 702 in year 5, corresponding to a 1.68% increase in annual NHS spending on GORD treatment in England and Wales. Discussion: While the time horizon was too short to capture some of the adverse events of PPIs and complications of GORD, such as the development of Barrett's esophagus or esophageal cancer, the use of RefluxStop™ was associated with a substantial reduction in surgical complications, including surgical failures, reoperations, and endoscopic esophageal dilations. This favorable clinical profile resulted in cost offsets for the NHS and contributed to the marginal budget impact of RefluxStop™ estimated in the current analysis. Conclusions: Introducing RefluxStop™ as a treatment option for patients with GORD in England and Wales may be associated with clinical benefits at the expense of a marginal budget impact on the NHS.

Costs of Digital Adherence Technologies for Tuberculosis Treatment Support, 2018-2021.

Digital adherence technologies are increasingly used to support tuberculosis (TB) treatment adherence. Using microcosting, we estimated healthcare system costs (in 2022 US dollars) of 2 digital adherence technologies, 99DOTS medication sleeves and video-observed therapy (VOT), implemented in demonstration projects during 2018-2021. We also obtained cost estimates for standard directly observed therapy (DOT). Estimated per-person costs of 99DOTS for drug-sensitive TB were $98 in Bangladesh (n = 719), $119 in the Philippines (n = 396), and $174 in Tanzania (n = 976). Estimated per-person costs of VOT were $1,154 in Haiti (87 drug-sensitive), $304 in Moldova (173 drug-sensitive), $452 in Moldova (135 drug-resistant), and $661 in the Philippines (110 drug-resistant). 99DOTS costs may be similar to or less expensive than standard DOT. VOT is more expensive, although in some settings, labor cost offsets or economies of scale may yield savings. 99DOTS and VOT may yield savings to local programs if donors cover infrastructure costs.

The health economics of an Alzheimer’s prevention therapy

AbstractBackgroundAmyloid reducing antibodies have been shown or suggested to slow decline in early Alzheimer’s disease (AD), and prevention trials in preclinical AD are ongoing. We estimate cost‐effectiveness of AD prevention from a payer perspective, which considers cost offsets and QALYs gains, and a societal perspective, which adds reduction in caregiver burden.MethodWe estimate cost‐effectiveness in the 2023 cohort of 55–79‐year‐olds with a Markov model under the following assumptions: Everyone would undergo an AD blood test (cost $125), which would generate positive or negative results in 80% of cases with sensitivity and specificity of 80% and inconclusive results in 20%. Individuals (80%) testing positive would go directly to treatment, the other 20% to confirmatory testing with PET (50%, cost of $4,000) or CSF (50%, cost of $600), receiving treatment accordingly. Individuals testing negative at any stage would return for another blood test in five years and those with inconclusive results in one. We assume average annual therapy cost of $5,850 per person (the list price of the PCSK9 inhibitors) for duration of 12 years, treatment effect of 50%, and four (baseline and 6, 12 and 18 month) MRIs ($400) for ARIA.ResultThe program would be cost‐effective from a payer perspective with cost of $45,157 and value of $53,721 per person. From a societal perspective, it would generate $24,704 in net value per person (Figure 1). If the treatment delayed progression by 25 percent, the program would no longer be cost‐effective from a payer or societal perspective. The treatment would have to eliminate the progression from preclinical AD to MCI to become cost‐neutral (Figure 2). Higher specificity of the blood test would decrease cost per person with no change in value generation and higher sensitivity would increase cost and decrease valueConclusionA prevention treatment that reduces the progression from preclinical AD to MCI by 50% could be economically viable from a payer perspective. The results are preliminary and need to be adjusted as more data become available, but the findings should stimulate a discussion among stakeholders about the contours and economic viability of such a prevention program.

Budget impact of oral nirmatrelvir/ritonavir in adults at high risk for progression to severe COVID-19 in the United States.

Nirmatrelvir/ritonavir (NMV/r) is indicated for the treatment of mild-to-moderate COVID-19 in adults who are at high risk for progression to severe COVID-19. NMV/r has also been authorized for emergency use by the US Food and Drug Administration for the treatment of mild-to-moderate COVID-19 in pediatric patients (aged 226512 years and weighing at least 40 kg) who are at high risk for progression to severe COVID-19. Understanding the budget impact of introducing NMV/r for the treatment of adults with COVID-19 is of key interest to US payers. To estimate the annual budget impact of introducing NMV/r in a US commercial health plan setting in the current Omicron COVID-19 era. A budget impact model was developed to assess the impact of NMV/r on health care costs in a hypothetical 1-million-member commercial health insurance plan over a 1-year period in the US population; clinical and cost inputs were derived from published literature with a focus on studies in the recent COVID-19 era that included vaccinated population and predominance of the Omicron variant. In the base-case analysis, it was assumed the only effect of NMV/r was a reduction in incidence (not severity) of hospitalization or death; its potential effect on post-COVID conditions was assessed in a scenario analysis. Outcomes included the number of hospitalizations, total cost, per patient per year (PPPY) costs, and per member per month (PMPM) costs. Sensitivity and scenario analyses were conducted to assess uncertainty around key model inputs. An estimated 29,999 adults were eligible and sought treatment with oral antiviral for COVID-19 over 1 year. The availability of NMV/r was estimated to reduce the number of hospitalizations by 647 with a total budget impact of $2,733,745, $91 PPPY, and $0.23 PMPM. NMV/r was cost saving when including post-COVID conditions with a -$1,510,780 total budget impact, a PPPY cost of -$50, and a PMPM cost of -$0.13. Sensitivity analyses indicated results were most sensitive to the risk of hospitalization under supportive care, risk of hospitalization with NMV/r treatment and cost of NMV/r. Treatment with NMV/r in the current COVID-19 era is estimated to result in substantial cost offsets because of reductions in hospitalization and modest budget impact to potential overall cost savings.

Estimating the impact of improved management of haemophilia a on clinical outcomes and healthcare utilisation and costs

ObjectiveHaemophilia A (HA) is associated with high clinical and healthcare burden. We developed an Excel-based model comparing current practice to improved management in severe HA patients currently managed on demand (OD). Outcomes included short- and long-term bleed events. Expected annual bleeds were estimated based on locally-derived OD annualised bleed rate (ABR), adjusted by relative prophylaxis-related ABRs (published literature). The objective of our study was to explore the impact of improving HA prophylaxis in target countries with limited published data (Algeria, Argentina, Chile, India, Malaysia, Mexico, Taiwan and Thailand). Bleed-related healthcare resource use (HCRU) and costs were estimated as a function of bleed type, with inputs obtained from local expert estimates. Clotting factor concentrates (CFC) consumption related to treatment and prophylaxis was estimated based on locally relevant dosing. CFC costs were not included.ResultsWhen 20% of OD patients were switched to prophylaxis, projected reduction in bleeds was estimated between 3% (Taiwan) through 14% (Algeria and India); projected reductions in hospitalisations ranged from 3% (Taiwan) through 15% (India). Projected HCRU-related annual cost savings were estimated at USD 0.45 m (Algeria), 0.77 m (Argentina), 0.28 m (Chile), 0.13 m (India), 0.29 m (Malaysia), 2.79 m (Mexico), 0.15 m (Taiwan) and 0.78 m (Thailand). Net change in annual CFC consumption ranged from a 0.05% reduction (Thailand) to an overall 5.4% increase (Algeria). Our model provides a flexible framework to estimate the clinical and cost offsets of improved prophylaxis. Modest increase in CFC consumption may be an acceptable offset for improvements in health and healthcare capacity in resource constrained economies.

Estimating Transfusion-Related Medical Costs and Associated Time Burden in Patients with Myelofibrosis: A Comparison of Momelotinib Vs Ruxolitinib Based on Simplify-1

Introduction: Myelofibrosis (MF) is a myeloproliferative neoplasm characterized by splenomegaly, debilitating symptoms, and bone marrow fibrosis. Transfusion-dependent (TD) anemia is present in one-quarter of patients (pts) with MF at diagnosis and becomes more common over time. Transfusion dependence imposes a high cost burden on healthcare systems, with annual total medical costs up to 9 times higher for TD pts than for non-TD pts (Gerds A, et al. ASH 2022. Abstract 1729). Momelotinib (MMB) is a Janus kinase (JAK) 1/JAK2/activin A receptor type 1 inhibitor that has demonstrated symptom, spleen, and anemia benefits in pts with MF across 3 phase 3 trials. Evidence in JAK inhibitor-naive pts comes from SIMPLIFY-1 (NCT01969838), a randomized, double-blind, phase 3 trial of MMB vs ruxolitinib (RUX). Eligible pts had International Prognostic Scoring System high-risk or intermediate-2-risk MF, or intermediate-1-risk MF associated with symptomatic splenomegaly, hepatomegaly, or anemia (hemoglobin &amp;lt;10 g/dL) and/or unresponsiveness to available non-JAK inhibitor therapy. MMB was associated with higher red blood cell (RBC) transfusion independence rates (66.5% vs 49.3%), lower transfusion dependence rates (30.2% vs 40.1%), and fewer RBC units transfused (median of zero units/month vs 0.4 units/month) compared with RUX by week 24. This study estimated the projected differences between MMB and RUX in total medical costs as well as cost and time burden associated with outpatient transfusion visits, based on results from SIMPLIFY-1, in all pts with MF and separately in those aged ≥65 years. Methods: Analyses were based on transfusion status (TD, transfusion independent [TI], or transfusion requiring [TR]) and mean rates of outpatient transfusion visits over 24 weeks in SIMPLIFY-1. TD was defined as ≥4 RBC units transfused or hemoglobin &amp;lt;8 g/dL in the prior 8 weeks, TI was defined as no RBC transfusions and all hemoglobin ≥8 g/dL in the prior 12 weeks, and TR was defined as being neither TD nor TI. Projected cost offsets for MMB relative to RUX were calculated based on observed transfusion status and rates over 24 weeks from SIMPLIFY-1 combined with cost estimates for TD vs TI/TR from the IBM MarketScan Database used to inform commercial health plans. Projected time savings were calculated similarly using transfusion rates from SIMPLIFY-1 and previously reported time burden estimates for transfusion visits in pts with TD β-thalassemia (Knoth RL, et al. EHA2022. Poster P1741). For pts aged ≥65 years, individual pt data from SIMPLIFY-1 and cost estimates from the Medicare fee-for-service database were used instead. Results: Based on the IBM MarketScan Commercial Database, projected average annual total medical cost savings based on week 24 transfusion status with MMB vs RUX were $20,215 per pt with baseline TD status and $23,991 per pt with baseline TI/TR status. Fewer outpatient transfusion visits with MMB vs RUX resulted in projected annual savings of $25,704 per pt with baseline TD status and $12,083 per pt with baseline TI/TR status. Among pts with baseline TD status, projected annual time savings in transfusion visits for MMB vs RUX (147 vs 253 hours) totaled 106 hours per pt (42 hours, preparation and waiting; 50 hours, transfusion and recovery; 15 hours, travel), a 42% reduction for MMB vs RUX. In the subgroup analysis that focused on pts aged ≥65 years, based on the Medicare fee-for-service database, projected average annual total medical cost savings with MMB vs RUX were $11,102 per pt with baseline TD status and $17,373 per pt with baseline TI/TR status. Fewer outpatient transfusion visits with MMB vs RUX resulted in projected annual savings of $28,826 per pt with baseline TD status and $18,255 per pt with baseline TI/TR status. Among pts aged ≥65 years with baseline TD status, projected annual time savings in transfusion visits accounted for MMB vs RUX (160 vs 279 hours) totaled 119 hours per pt (47 hours, preparation and waiting; 56 hours, transfusion and recovery; 16 hours, travel), a 43% reduction for MMB vs RUX. Conclusions: Reductions in transfusion dependence and transfusion visits for MMB vs RUX were associated with projected healthcare system savings in transfusion costs and transfusion-related time burden in JAK inhibitor-naive pts with MF, including in subgroup analyses of pts aged ≥65 years.

Budget impact of introducing oral semaglutide to the public healthcare benefit package in Saudi Arabia

BackgroundThe Kingdom of Saudi Arabia (KSA) has embarked on a Health Sector Transformation Program as part of the Kingdom’s Vision 2030 initiatives with the facilitation of access to healthcare services for the millions in KSA with diabetes an essential part of the Program. Decision-making tools, such as budget impact models, are required to consider the addition of new medications like oral semaglutide that have multifaceted health benefits and address barriers related to therapeutic inertia to reduce diabetes-related complications.ObjectiveTo determine the financial impact of the introduction of oral semaglutide as a treatment option for people with type 2 diabetes mellitus (T2DM) in KSA.MethodsFrom the public payer’s perspective, the budget impact model estimates the costs before and after the introduction of oral semaglutide over a 5-year time horizon. The budget impact of introducing oral semaglutide (primary comparator) compared with three different classes of diabetes medicines: glucagon-like peptide-1 receptor agonists (GLP-1), sodium-glucose transport protein 2 inhibitors (SGLT 2i) and dipeptidyl peptidase 4 inhibitors (DDP-4i) have been calculated based on the projected market shares. The model includes the cost of care through the incorporation of health outcomes that have an impact on the national payer’s budget in Saudi Riyals (SAR).ResultsThe budget impact over the five-year time horizon indicates a medication cost increase (17,424,788 SAR), and cost offsets which include a difference in diabetes management costs (-3,625,287 SAR), CV complications costs (-810,733 SAR) and weight loss savings of 453,936 SAR. The cumulative total cost difference is 12,427,858 SAR (0.66%).ConclusionThe introduction of oral semaglutide 14 mg as a second-line treatment option after metformin is indicated as budget-neutral to slightly budget-inflating for the public pharmaceutical formulary of KSA. The price difference is offset by positive health outcomes and costs. This conclusion was confirmed through a probabilistic sensitivity analysis.
