Aims: To assess the long-term effects of lecanemab plus standard of care (SoC) compared with SoC alone in a cohort of patients with early Alzheimer's disease (AD; mild cognitive impairment [MCI] due to AD, or mild AD dementia) using different modeling approaches and data from Clarity AD (NCT0388745538).
Methods: A Markov model was employed using health states based on disease severity, long-term institutionalization, and death, with disease severity defined using the Clinical Dementia Rating - Sum of Boxes (CDR-SB) classification for MCI due to AD, and Mild, Moderate, and Severe AD. State transitions during the first 18 months of treatment were estimated using either patient count data (Approach 1) or multistate survival analysis (Approach 2). Transition probabilities beyond 18 months for the lifetime of the cohort were informed by longitudinal natural history data for the SoC arm with a hazard ratio for time-to-worsening health state applied to estimate outcomes in the lecanemab arm.
Results: Over a lifetime horizon, the model predicted a delayed time to Mild, Moderate, and Severe AD for patients treated with lecanemab compared to SoC by 1.31, 1.85, and 2.04 years, respectively when using Approach 1. Patients treated with lecanemab experienced a survival benefit of 1.36 years, comprised of an additional 1.85 years in early AD and 0.49 years less in moderate and severe AD, compared to patients treated with SoC alone. The model also predicted that compared to SoC, lecanemab increased the time in community care and reduced time spent in institutional care. Results were similar when using Approach 2.
Limitations: Long-term disease progression was informed by constant annual transition probabilities derived from the published literature.
Conclusions: Patients treated with lecanemab experience delayed progression to Moderate and Severe AD, resulting in additional life-years (LYs) and reduced time in institutional care.
目的:使用不同的建模方法和Clarity AD (NCT0388745538)的数据,评估莱卡耐单抗加标准治疗(SoC)与单独使用标准治疗(SoC)在早期阿尔茨海默病(AD; AD所致轻度认知障碍[MCI]或轻度AD痴呆)患者队列中的长期效果。方法:采用基于疾病严重程度、长期住院和死亡的健康状态的马尔可夫模型,疾病严重程度使用临床痴呆评分-盒和(CDR-SB)分类来定义由AD引起的MCI,以及轻度、中度和重度AD。使用患者计数数据(方法1)或多状态生存分析(方法2)估计治疗前18个月的状态转变。通过SoC组的纵向自然史数据了解队列生命周期中超过18个月的过渡概率,并应用lecanemab组的健康状态恶化时间的风险比来估计结果。结果:在整个生命周期中,该模型预测,与SoC相比,使用方法1时,lecanemab治疗的患者向轻度、中度和重度AD的延迟时间分别为1.31年、1.85年和2.04年。与单独使用SoC治疗的患者相比,接受lecanemab治疗的患者的生存期延长了1.36年,其中早期AD患者的生存期延长了1.85年,中度和重度AD患者的生存期缩短了0.49年。该模型还预测,与SoC相比,lecanemab增加了社区护理时间,减少了机构护理时间。方法2的结果相似。局限性:长期疾病进展是通过从已发表的文献中导出的恒定年度转移概率来告知的。结论:接受lecanemab治疗的患者延缓了中度和重度AD的进展,导致额外的生命年(LYs)和减少了在机构护理的时间。

Detecting and treating cancer at an early stage is critical for improving patient survival, quality of life, and health system efficiency. Early diagnosis offers substantial clinical benefits, reduces the need for aggressive treatments associated with advanced disease, and lowers healthcare costs. Despite these benefits, disparities in early-stage detection persist across tumor types due to challenges in screening, public awareness, and the aggressive nature of certain cancers. While early-stage diagnosis generally offers a better prognosis than late-stage detection, disease recurrence remains a significant reality and concern. Many patients experience a relapse of cancer despite initial curative treatment, which adversely affects their survival, quality of life, and financial stability. While effective new treatments for early-stage cancers have emerged, including immunotherapy and targeted therapies, barriers to reimbursement and access persist. One challenge is the absence of mature overall survival data at the time of regulatory and reimbursement approvals for most tumor types, which can result in delayed decision-making, reduced patient access, and worse outcomes. This policy paper combines insights from clinicians, health economists, outcomes researchers, and policy experts to address gaps in early-stage cancer care and provide recommendations to enhance diagnosis rates, reduce the burden of recurrence, and optimize access to innovative treatments. Central to these recommendations is the integration of early cancer care into national cancer control plans, including robust data collection and monitoring, as well as improvements in health literacy. A key factor is the use of early clinical endpoints that measure key outcomes in addition to overall survival, providing timely insights into treatment effectiveness that can guide early regulatory and reimbursement decisions prior to reaching overall survival maturity. This paper is a call to action for relevant stakeholders to take a coordinated approach that optimizes outcomes for cancer patients by promoting early detection and treatment.

Aim: The objective of this study was to evaluate the value of three secondary stroke prevention strategies in Australia: the Cardioform and Amplatzer Patent Foramen Ovale (PFO) closure devices, and medical management.
Materials and methods: An eight-state Markov model was employed to simulate a cohort of 1,000 patients with a history of PFO-associated stroke over a five-year time horizon. Treatment strategies included Cardioform, Amplatzer, and medical therapy alone. Effectiveness data were derived from the REDUCE and RESPECT trials, a matching-adjusted indirect comparison (MAIC), and prior cost-effectiveness studies. Costs, presented from an Australian healthcare perspective and expressed in 2023 AUD, were used to calculate quality-adjusted life-years (QALYs), strokes prevented, the incremental cost-effectiveness ratio (ICER), and net monetary benefit (NMB).
Results: Compared to Amplatzer, treatment with Cardioform yielded cost savings to the Australian health care systems (NMB of AUD 3.7 million) and improved patient outcomes (yielded 26.48 additional QALYs and prevented 28 more recurrent strokes). Relative to medical therapy alone, Cardioform resulted in improved patient outcomes and was cost-effective, with an ICER of $11,784/QALY. Cardioform provides an NMB of AUD 14.3 million and yielded 374.5 additional QALYs beside preventing 67 more strokes compared to medical therapy alone.
Conclusion: Cardioform appears more cost-effective in the prevention of secondary PFO-associated strokes, supporting its adoption in clinical practice.

Objective: The aim of this study was to propose a methodology for assessing the cost-effectiveness of healthcare services at the population level and to establish a corresponding cost-effectiveness threshold from the payer's perspective, taking into account economic sustainability and the data available to the payer.
Materials and methods: Analysis was based on data from a Czech health insurance fund covering the period 2014-2024. A binary health status metric, Health Services Derived Disability (HSDD), was developed and calibrated against the Healthy Life Years (HLY) indicator. Subsequently, two cost-effectiveness threshold values were derived from real-world data on healthcare expenditures, mortality, and HSDD: CETLY (Cost-Effectiveness Threshold per Life Year) and CETDFLY (Cost-Effectiveness Threshold per Disability-Free Life Year). Cost-effectiveness can be evaluated using both thresholds within a net monetary benefit framework.
Results: CETLY was derived from expenditures in the 0-69 age group, while the calculation of CETDFLY excluded individuals who died in a given year to avoid distortion from high end-of-life costs. For the year 2024, CETLY was estimated at 465,500 CZK (20,056 USD; 35,918 USD adjusted for PPP), and CETDFLY at 96,600 CZK (4,162 USD; 7,454 USD adjusted for PPP). In nominal terms, the year-on-year increase in CETLY was approximately 7.9%, and in CETDFLY approximately 6.5%.
Limitations: The methodology does not account for the subjective dimension of quality of life and may underestimate certain types of disability. HSDD is a binary indicator that does not reflect severity levels. The transferability of the methodology to other healthcare systems depends on the equity of access to health care and the availability of administrative data.
Conclusion: The proposed methodology enables continuous assessment of the cost-effectiveness of healthcare services at the population level using administrative data. It can serve as a supporting tool for payers in the evaluation, and optimization of healthcare programs and interventions.

Aims: Intravenous (IV) lecanemab is approved for the treatment of patients with early Alzheimer's disease (AD); a subcutaneous (SC) option may offer additional benefits. We assessed the overall value of SC treatments, and direct/indirect outcomes associated with IV and SC lecanemab.
Methods and materials: For the narrative review, PubMed was searched (February 2025) for studies comparing patient preferences for IV/SC treatment administration published between 2015-2025. Study eligibility was determined using patient, intervention, comparator, outcomes, and study criteria. For the decision-analytic model, a Markov model was developed with four lecanemab treatment scenarios. Scenarios one to three included IV initiation (10 mg/kg biweekly) to month 18, followed by either IV initiation continued (10 mg/kg biweekly), SC maintenance (250 mg weekly) or IV maintenance (10 mg/kg every 4 weeks). Scenario four included SC initiation (500 mg weekly) for an 18-month period, followed by SC maintenance (250 mg weekly). Outcomes were administration time/frequency; patient, caregiver, and healthcare professional time; and caregiver productivity loss.
Results: Forty-three publications reported patient treatment preferences. Most (88.4%) reported that patients preferred SC over IV. Key reasons for this were time savings (n = 13/43 studies; 30.2%), convenience (n = 11/43; 25.6%), treatment frequency (n = 12/43; 27.9%). Two studies (n = 2/43; 4.7%) reported an IV preference over SC; for three studies (n = 3/43; 7.0%), treatment preference was driven by administration frequency. Decision-analytic modeling of lecanemab treatment scenarios revealed that IV initiation to IV maintenance had the lowest number of administrations, whereas SC initiation to SC maintenance had the lowest number of treatment hours and caregiver productivity losses.
Limitations: Caution must be taken when generalizing these results for all AD patients.
Conclusions: SC treatments show value as a therapeutic option. IV and SC lecanemab availability may offer benefits to patients, caregivers, and society, and improve shared decision making.

Aim: To evaluate the cost-effectiveness of sotorasib versus adagrasib in the second- and later lines of treatment for KRAS G12C non-small cell lung cancer (NSCLC) from a US private payer perspective.
Methods: A standard three-state partitioned survival model was used with a 20 year (life-time) horizon. Equivalent progression-free survival (PFS) and overall survival (OS) were assumed in the base case based on published matching-adjusted indirect comparisons (MAICs) of Phase 2 and 3 data, and time-to-death utilities applied. Treatment-related adverse events (TRAEs) common to both treatments were included. Direct costs and health benefits were discounted at 1.5% annually. Model robustness was explored through probabilistic sensitivity analysis (PSA) and inputs varied in scenario analyses.
Results: In the base case, sotorasib was more cost-effective than adagrasib, driven by lower acquisition cost and TRAE frequency. Total discounted costs were $18,004 higher for adagrasib than sotorasib ($246,557 vs $228,553), comprising: drug acquisition ($9,478), TRAE management ($4,103) and comedications (antiemetics and antidiarrheal agents; $4,424). Sotorasib was dominant at equivalent efficacy (1.20 quality-adjusted life-years [QALYs]). Net monetary benefit was $18,031 at a willingness-to-pay threshold (WTP) of $150,000/QALY. In the PSA, there was a higher probability of sotorasib being more cost-effective than adagrasib at all WTP thresholds (62% at a WTP of $150,000/QALY). Sotorasib was consistently more cost-effective than adagrasib in scenario analyses exploring relative efficacy, discount rate, time horizon, and utilities, with ICERs well below the $150,000/QALY WTP threshold.
Limitations: MAIC-based comparative effectiveness was used in the absence of head-to-head trial data; conclusions informed by MAIC should be interpreted with caution; long-term projections are limited without mature OS data; published data sources may be based on different populations.
Conclusion: Sotorasib was more cost-effective than adagrasib in the second- and subsequent-line treatment of KRAS G12C NSCLC, based on current efficacy and safety data.

Aims: Use of bioprosthetic tissue valves in surgical aortic valve replacement (SAVR) has increased in recent years. The effect of novel bovine pericardial tissue valves on short-term costs and utilization has not been established. We assessed INSPIRIS RESILIA aortic tissue valves (*Edwards Lifesciences, Irvine CA) during SAVR hospitalization and 90 days post-discharge compared to other tissue valves for all ages, and to mechanical valves for patients of shared decision-making age (50-65).
Materials and methods: Retrospective observational study using US hospital data. Adults admitted for first-time SAVR 2018-2021 with identifiable tissue or mechanical valves were analyzed. Outcomes were adjusted for demographics, comorbidities, procedure and hospital characteristics using generalized linear modeling.
Results: 20,125 patients were analyzed; majority were male, with elective procedures in academic hospitals. Compared to other tissue valves, length of stay and ICU stay were shorter with INSPIRIS (p < 0.001). In-hospital mortality was not statistically different. Readmissions at 30 days were 7.1% with INSPIRIS, 9.0% other tissue valves; 10.4% vs. 13.0% at 90 days (both p < 0.001). Reduced cost of readmission (-$1,013 at 90 days) partially offset the difference of $2,429 in initial hospitalization cost. INSPIRIS valves compared to mechanical valves (ages 50-65) showed similar patterns in utilization. In-hospital mortality was lower with INSPIRIS than mechanical valves (2.0% vs. 3.2%, p = 0.009), but did not differ when limited to isolated SAVR only. Initial hospitalization cost was higher for INSPIRIS ($7,079, p < 0.001), with lower 90-day readmissions cost (-$899, p < 0.05).
Limitations: Non-randomized analysis of real-world data.
Conclusions: Patients undergoing SAVR with INSPIRIS valves had shorter length of stay and fewer readmissions compared to other tissue valves and to mechanical valves. Reduced cost of readmissions partially offset higher cost of initial SAVR admission. Further research is warranted to explore this association between valve used and utilization outcomes.
目的:近年来,生物修复组织瓣膜在外科主动脉瓣置换术(SAVR)中的应用越来越多。新型牛心包组织瓣膜对短期成本和利用的影响尚未确定。我们评估了在SAVR住院期间和出院后90天内INSPIRIS RESILIA主动脉组织瓣膜(*Edwards Lifesciences, Irvine CA)与所有年龄的其他组织瓣膜的比较,以及与共同决策年龄(50-65岁)的患者的机械瓣膜的比较。材料和方法:采用美国医院资料进行回顾性观察研究。分析了2018-2021年首次接受SAVR的成人,其组织或机械瓣膜可识别。采用广义线性模型,根据人口统计学、合并症、手术和医院特征对结果进行调整。结果:共分析20125例患者;大多数是男性,在学术医院进行选择性手术。与其他组织瓣膜相比,INSPIRIS的住院时间和ICU住院时间较短(p p p = 0.009),但仅限于孤立的SAVR时没有差异。INSPIRIS的初始住院费用较高(7,079美元,p。局限性:对真实数据的非随机分析。结论:与其他组织瓣膜和机械瓣膜相比,使用INSPIRIS瓣膜进行SAVR的患者住院时间更短,再入院率更低。再入院费用的降低部分抵消了初次SAVR入院较高的费用。有必要进一步研究阀门使用与利用结果之间的关系。

Aims: Systemic corticosteroids (SCS) are used to manage asthma exacerbations. Among the broad population of patients with asthma, SCS-related risk of adverse events (AEs), health care resource utilization (HCRU), and costs remain unclear.
Materials and methods: This retrospective cohort study used the Optum Research Database claims to identify adults with asthma from 1/1/2017 to 6/30/2022. The index date was the earliest SCS claim for SCS users; non-SCS users were randomly selected and adjusted proportionally to SCS users by index year. SCS use was measured during the first 12 months of follow-up. Inverse probability of treatment weighting balanced the two cohorts for selected baseline demographic and clinical characteristics. SCS users were further stratified into low, medium, and high dose sub-cohorts. SCS-related AEs were assessed up to 48 months, while HCRU and costs were assessed during the first 12 months of follow-up. A generalized linear model (GLM) analyzed follow-up costs by SCS exposure.
Results: The 130,739 patients included 55,363 non-SCS users (42.3%), while 75,376 were SCS users stratified into 60,319 low-, 12,235 medium-, and 2,822 high-dose users. The mean age was 49.6 years; 61.8% were female and 68.9% were non-Hispanic White. SCS users had a significantly greater risk of new-onset acute and chronic SCS-related AEs, increasing incrementally with dose exposure (all p < .001) across numerous physiological systems. Follow-up HCRU and costs also rose incrementally with dose exposure (all p < .001). Compared with non-users, SCS-related costs were 1.43, 1.97, and 3.21 times higher among low-, medium-, and high-dose users, respectively. The adjusted GLM predicted a 9.9% cost increase per 100 mg of prednisone equivalents.
Limitations: Retrospective administrative claims studies cannot randomize patients and may not capture all patient events.
Conclusions: Among a broad population of adults with asthma, even low doses of SCS were associated with significantly increased risk of new-onset AEs, HCRU, and costs.

Introduction: Despite the inclusion of pneumococcal conjugate vaccines (PCV) in the pediatric national immunization program (NIP) since 2017, Romania continues to face a substantial clinical, economic, and societal burden of pneumococcal disease. Higher-valent vaccines, such as 20-valent PCV (PCV20), offer broader serotype coverage versus the current standard of care (13-valent PCV; PCV13) with the potential to reduce disease burden. To test this, we conducted a cost-effectiveness analysis of switching from PCV13 or a potential future comparator (15-valent PCV; PCV15), both under a 2 + 1 schedule, to PCV20 under a 3 + 1 schedule in the Romanian pediatric NIP.
Methods: A population-based, multi-cohort Markov model with a target population of children aged <2 years was utilized to estimate the cost and health impact of PCV20 versus lower-valent comparators over 10 years. The model adopted a Romanian societal perspective, encompassing both direct and indirect costs, with an annual cycle. Sensitivity and scenario analyses were conducted to assess the robustness of the model and its assumptions.
Results: In the base-case analysis, PCV20 demonstrated dominance versus PCV13 and PCV15 (i.e. was more effective and less costly), with total predicted cost-savings of 79,123,267 and 206,623,098 Romanian Leu, respectively, plus reduction in pneumococcal disease cases by 246,245 and 223,914, respectively. The majority of sensitivity and scenario analyses of both pairwise comparisons were aligned with the base case.
Conclusion: The results of this analysis indicate that PCV20 implementation into the Romanian pediatric NIP would greatly reduce pneumococcal disease burden and would be a cost-effective approach versus PCV13 or PCV15 from a societal perspective over 10 years.
