Tenecteplase for ischemic stroke at 4.5 to 24 hours without thrombectomy: a cost-utility analysis from the perspective of Chinese healthcare system

BackgroundTenecteplase improves functional outcomes in acute ischemic stroke (AIS) patients treated 4.5 to 24 h after symptom onset who do not undergo thrombectomy. However, its cost-utility remains unexamined.MethodsA hybrid model combining a short-term decision tree and a long-term Markov model was developed to simulate the costs and quality-adjusted life years (QALYs) for Chinese patients with AIS at 4.5 to 24 h, who did not undergo thrombectomy. Clinical data were sourced from the TRACE-III trial, while cost data were obtained from the China National Stroke Registry and the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China database. The primary outcome was the incremental cost-effectiveness ratio (ICER). Secondary outcomes included total costs, total QALYs and remaining life expectancy, as well as the incremental cost, incremental QALYs, and incremental remaining life expectancy. One-way sensitivity analysis, probabilistic sensitivity analysis (PSA), and scenario analysis were conducted to test the robustness of the results.ResultsFor a Chinese patient with AIS treated within 4.5 to 24 h after symptom onset without thrombectomy, adding tenecteplase to standard care resulted in an incremental cost of 2,536 Chinese Yuan (CNY) and an increase of 0.40 QALYs, yielding an ICER of 6,386 CNY per QALY. One-way sensitivity analysis revealed that the most significant factors influencing the ICER were the efficacy and cost of tenecteplase. PSA and scenario analyses confirmed the robustness of these results.ConclusionCompared to standard medical treatment alone, administering intravenous tenecteplase between 4.5 and 24 h after onset for Chinese patients with AIS who did not undergo thrombectomy, is highly cost-effective.

Cost-effectiveness of angiographic quantitative flow ratio-guided coronary intervention: A multicenter, randomized, sham-controlled trial.

The FAVOR (Comparison of Quantitative Flow Ratio Guided and Angiography Guided Percutaneous Intervention in Patients with Coronary Artery Disease) III China trial demonstrated that percutaneous coronary intervention (PCI) lesion selection using quantitative flow ratio (QFR) measurement, a novel angiography-based approach for estimating fractional flow reserve, improved two-year clinical outcomes compared with standard angiography guidance. This study aimed to assess the cost-effectiveness of QFR-guided PCI from the perspective of the current Chinese healthcare system. This study is a pre-specified analysis of the FAVOR III China trial, which included 3825 patients randomized between December 25, 2018, and January 19, 2020, from 26 centers in China. Patients with stable or unstable angina pectoris or those ≥72 hours post-myocardial infarction who had at least one lesion with a diameter stenosis between 50% and 90% in a coronary artery with a ≥2.5 mm reference vessel diameter by visual assessment were randomized to a QFR-guided strategy or an angiography-guided strategy with 1:1 ratio. During the two-year follow-up, data were collected on clinical outcomes, quality-adjusted life-years (QALYs), estimated costs of index procedure hospitalization, outpatient cardiovascular medication use, and rehospitalization due to major adverse cardiac and cerebrovascular events (MACCE). The primary analysis calculated the incremental cost-effectiveness ratio (ICER) as the cost per MACCE avoided. An ICER of ¥10,000/MACCE event avoided was considered economically attractive in China. At two years, the QFR-guided group demonstrated a reduced rate of MACCE compared to the angiography-guided group (10.8% vs. 14.7%, P <0.01). Total two-year costs were similar between the groups (¥50,803 ± 21,121 vs. ¥50,685 ± 23,495, P = 0.87). The ICER for the QFR-guided strategy was ¥3055 per MACCE avoided, and the probability of QFR being economically attractive was 64% at a willingness-to-pay threshold of ¥10,000/MACCE avoided. Sensitivity analysis showed that QFR-guided PCI would become cost-saving if the cost of QFR were below ¥3682 (current cost: ¥3800). Cost-utility analysis yielded an ICER of ¥56,163 per QALY gained, with a 53% probability of being cost-effective at a willingness-to-pay threshold of ¥85,000 per QALY gained. In patients undergoing PCI, a QFR-guided strategy appears economically attractive compared to angiographic guidance from the perspective of the Chinese healthcare system.

Sequential biologic therapy in the treatment of active psoriatic arthritis in China: a cost-effectiveness analysis.

Compared with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), biologics are more effective and are recommended to be included in the sequential treatment for psoriatic arthritis (PsA) patients. However, biologics are expensive and the cost-effectiveness of sequential biologic therapy in China remains unknown. The purpose of this study is to evaluate the cost-effectiveness of different sequential treatment option for PsA patients who have not responded to csDMARDs from the perspective of Chinese healthcare system. We constructed a discrete event simulation model to evaluate the cost-effectiveness of 7 monotherapy treatments and 32 sequential treatments. In sequential therapy, two different types of biologics were used as first-line and second-line treatments, respectively, with the best supportive care (BSC) as the third-line treatment. The primary outcomes included total treatment costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs). One-way and probability sensitivity analyses were performed to explore the uncertainty of our model. Compared to all other strategies, initiating with secukinumab followed by etanercept (SEC-ETN) provided the highest health benefits. At a willingness-to-pay (WTP) threshold of US $38,161 per QALY, SEC-ETN was the most cost-effective strategy, with an ICER of $20,837 per QALY. One-way sensitivity analysis and probabilistic sensitivity analysis results confirmed the robust of this conclusion. In China, SEC-ETN may be the most cost-effective strategy for patients who have failed treatment with csDMARDs and have not previously used biologics. The results provide evidence for identifying the optimal biologic treatment strategy for PsA patients in China. Key Points • Compared with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), biologics are more effective and are recommended to be included in the sequential treatment for psoriatic arthritis (PsA) patients. However, the cost-effectiveness of sequential biologic therapy in China remains unclear. • At a willingness-to-pay threshold of $38,161, initiating with secukinumab followed by etanercept (SEC-ETN) was cost-effective strategy, outperforming other strategies. • From the perspective of the Chinese healthcare system, the optimal biologic treatment strategy was SEC-ETN in China.

Cost-effectiveness analysis of a first-line treatment with cadonilimab plus platinum-based chemotherapy with or without bevacizumab for persistent, recurrent, or metastatic cervical cancer in China: COMPASSION-16 trial.

The addition of cadonilimab to first-line platinum-based chemotherapy with or without bevacizumab significantly improved progression-free survival (PFS) and overall survival (OS) in patients with persistent, recurrent, or metastatic cervical cancer. However, the economic value of using this novel therapy for this indication is currently unknown. The aim of this study is to evaluate the cost-effectiveness of the addition of cadonilimab to first-line standard chemotherapy for patients with persistent, recurrent, or metastatic cervical cancer from the perspective of Chinese healthcare system. A partitioned survival model was constructed to compare the cost-effectiveness of cadonilimab versus placebo in patients enrolled in the COMPASSION-16 trial. Cost, life-year, quality-adjusted life-year (QALY), incremental cost-effectiveness ratio (ICER), incremental net health benefit (INHB), and incremental net monetary benefit (INMB) were calculated for 2 treatment strategies. Sensitivity, scenario, and subgroup analyses, and value of information analysis (EVPI) were performed. Cadonilimab provided an additional 1.18 QALYs and $89,528.64 compared with placebo, which resulted in an ICER of $75,944.56/QALY. At the willingness-to-pay threshold of $38,042.49/QALY, INHB was estimated to be -1.17 QALYs, while INMB amounted to -$44,681.55 and EVPI was calculated as $71.40/person. Sensitivity analyses revealed that the model was most sensitive to hazard ratio (HR) for OS and PFS, and the probability of cadonilimab being cost-effective was 0.70%. To achieve cost-effectiveness, the price of cadonilimab must be reduced by approximately 50%. Subgroup analysis found that all subgroups unfavored cadonilimab by varying the HR for OS and PFS. Scenario analyses showed using life-year as effectiveness, altering time horizon and selection of survival analysis did not reverse results. Although the use of cadonilimab resulted in clinical benefit, it was not deemed cost-effective as a first-line therapy for persistent, recurrent, or metastatic cervical cancer in China. Lowering the price of cadonilimab may enhance its cost-effectiveness.

Cost-effectiveness analysis of gumarontinib versus savolitinib for the treatment of advanced or metastatic NSCLC with MET exon 14 skipping mutations in China using partitioned survival model.

Both gumarontinib and savolitinib have demonstrated efficacy in treating non-small-cell lung cancer (NSCLC) with tumors harboring mesenchymal-epithelial transition factor gene exon 14 (METex14) skipping. However, the comparison of their efficacy and pharmacoeconomics profiles remains limited. This study aims to evaluate the cost-effectiveness of gumarontinib versus savolitinib for the treatment of METex14 skipping NSCLC in China. A 3-state partitioned survival model (PSM) was developed with lifetime horizon from the perspective of Chinese healthcare system. Survival inputs were based on an unanchored matching-adjusted indirect comparison using individual patient data from GLORY trial to adjust for patient characteristics in NCT02897479. Costs and outcomes were discounted at an annual rate of 5%. Sensitivity and scenario analyses were conducted to explore model uncertainty. Gumarontinib gained an additional 0.10 QALYs at an incremental cost of $1,893 compared to savolitinib, resulting in the ICERs of $19,243/QALY, which is below the threshold of 3 times the GDP per capita in China ($35,007 per capita in 2022). Sensitivity and scenario analyses confirmed the robustness of the base-case results. Gumarontinib is a cost-effective option compared to savolitinib for METex14 skipping NSCLC in China.

Cost-effectiveness analysis of PD-L1 testing associated with pembrolizumab for first-line treatment of advanced non-small cell lung cancer in China.

Lung cancer is the leading cause of cancer-related deaths in China, and pembrolizumab shows differential efficacy in advanced non-small cell lung cancer (NSCLC) with different PD-L1 expression levels. To assess the cost-effectiveness of PD-L1 testing associated with pembrolizumab for first-line treatment of NSCLC from the perspective of Chinese healthcare system. Over a lifetime horizon, a three-state partitioned survival model was developed to assess the cost-effectiveness of PD-L1 testing and no PD-L1 testing. In the PD-L1 testing group, patients were stratified by PD-L1 tumor proportion score ≥ 50%, 1-49%, or < 1% and received pembrolizumab monotherapy, pembrolizumab plus chemotherapy, or chemotherapy alone, respectively. In the non-PD-L1 testing group, all patients received pembrolizumab plus chemotherapy. Model inputs were obtained from published literature and a healthcare price database, and clinical outcomes from two randomized clinical trials were used. The net monetary benefit (NMB) was estimated for the PD-L1 testing group versus the non-PD-L1 testing group. Deterministic and probabilistic sensitivity analyses, and scenario analyses were conducted to assess robustness of results. Using PD-L1 testing to guide treatment led to cost savings of $49,392.7 and a reduction in quality-adjusted life years (QALYs) of 0.234, resulting in a positive NMB of $46,421.7 at a willingness-to-pay (WTP) threshold of $12,680.8/QALY (GDP per capita in China, 2023). Findings were robust across sensitivity and scenario analyses. Using PD-L1 testing to guide first-line pembrolizumab treatment in patients with advanced NSCLC is a cost-effective strategy at a WTP threshold of $12,680.8/QALY for China.

Cost-effectiveness of the addition of sintilimab as a first-line therapy for locally advanced or metastatic oesophageal squamous cell carcinoma: a Chinese healthcare system perspective

BackgroundThe ORIENT-15 double-blind randomized controlled trial demonstrated that the addition of sintilimab to chemotherapy for locally advanced or metastatic oesophageal squamous cell carcinoma (OSCC) resulted in better clinical outcomes. In this analysis, we sought to evaluate the cost-effectiveness of sintilimab as a first-line treatment for locally advanced or metastatic OSCC from a healthcare system perspective in China.MethodsA partitioned survival model was constructed to perform a cost-effectiveness analysis comparing chemotherapy alone with sintilimab for locally advanced or metastatic OSCC patients. Clinical data were obtained from the ORIENT-15 trial and extrapolated to 10 years. Health state utilities and costs were sourced from the literature and from public healthcare institutions. The primary outcomes included the incremental cost-effectiveness ratio (ICER) and quality-adjusted life-years (QALYs). Two different sensitivity analyses, one-way and probabilistic, were performed to assess model uncertainty.ResultsSintilimab-based chemotherapy was more costly ($31699.21 vs. $20687.42) and more effective (0.74 vs. 0.53) than placebo-based chemotherapy, resulting in an ICER of $51908.19 /QALY, which is greater than the willingness-to-pay (WTP) threshold of China ($38223/QALY). Sensitivity analysis demonstrated that the PFS and cost of sintilimab were the major influencing factors affecting the results.ConclusionsIn patients with locally advanced or metastatic OSCC, sintilimab chemotherapy could improve survival time and health benefits compared with traditional chemotherapy, but the present analysis suggests that sintilimab is not a cost-effective treatment option in China.

Revisiting cost-effectiveness of folic acid supplementation in primary stroke prevention in China: considering vitamin B12 deficiency masking issue

ObjectivesTo identify the cost-effectiveness of four policy options related to folic acid supplements after considering the side effects of masking vitamin B12 (B12) deficiency in primary stroke prevention for hypertensive patients in China.Study DesignA cost-effectiveness analysis.MethodsFour policies were considered: Policy A, Do nothing to address folate status in hypertensive patients at risk for stroke; Policy B, Folate supplementation without pre-screening for vitamin B12 deficiency; Policy C, Folate supplementation with pre-screening all patients for B12 deficiency and add B12 supplements if B12 is deficient; and Policy D, Folate supplementation only for those whose folate is deficient, pre-screen all patients for both B12 and folate deficiencies and add B12 supplements if B12 is deficient. A decision tree with a five-year period of intervention based on the China Stroke Primary Prevention Trial (CSPPT) from the Chinese healthcare system perspective estimated incremental cost-effectiveness ratio (ICER) for Policy B, Policy C and Policy D vs. Policy A.ResultsAt a willingness to pay (WTP) threshold of 3 times the national GDP per capita ($38,198), Policy B was not cost-effective compared to Policy A, with an ICER of $47,968 per QALY due to QALYs lost introduced by the delayed diagnosis of B12 deficiency and the potentially underestimated costs associated with treating neuropathy. However, Policy C and Policy D were cost-effective compared to Policy A, with an ICER of $32,615 and $20,287 per QALY, respectively. A probabilistic sensitivity analysis showed that there would be a 72.7% and 83.5% chance that the additional cost of Policy C and Policy D, compared with Policy A, was at or below the WTP threshold.ConclusionsFolate supplementation with integrated screening for B12 and folate deficiencies is considered the most cost-effective strategy for primary stroke prevention in hypertensive elderly patients in China. Future research should focus on advancing precision medicine to assess the feasibility and cost-effectiveness of nationwide implementation across diverse sub-populations within the context of integrated screening, ensuring efficient and tailored public nutrition strategy delivery.

Long-Term Clinical and Economic Effects of Switching to Once-Weekly Semaglutide from Other GLP-1 RAs Among Patients with Type2 Diabetes in China: A Modeling Projection Study.

Previous studies, using clinical trial data, demonstrated that once-weekly (OW) semaglutide is dominant versus other glucagon-like peptide1 receptor agonists (GLP-1 RAs) in China. This study aims to evaluate the long-term clinical and economic effects of switching to OW semaglutide from other GLP-1 RAs among patients with type2 diabetes mellitus (T2DM) in China. The Institute of Health Economics Diabetes Cohort Model (IHE-DCM) was used to project life expectancy, quality-adjusted life years (QALYs), and total direct medical cost over 40years from a Chinese healthcare system perspective. Baseline characteristics, clinical effectiveness, and the treatment dose of OW semaglutide were derived from previously real-world studies. Patients were assumed to switch to semaglutide or continue previous GLP-1 RAs for 3years and change to intensive therapy. Drug prices were based on the median bidding price in January 2024 in China. Costs of other GLP-1 RAs were calculated on the basis of their market share in China. All costs were accounted as 2023 Chinese yuan (CNY). A discount of 5% was applied. One-way sensitivity analyses and probabilistic sensitivity analyses were used to test the robustness of the base-case result. The results show that switching to OW semaglutide from other GLP-1 RAs among patients with T2DM in China can improve life expectancy by 0.02years and afford an additional 0.12 QALYs per patient. Meanwhile, switching to OW semaglutide is associated with decreased total lifetime direct medical costs of 4204 CNY per patient, mainly resulting from savings in microvascular costs (2214 CNY) and macrovascular costs (1228 CNY). Sensitivity analyses show the robustness of modeling projection findings. Based on real-world data from China, this modeling projection study demonstrates that switching to OW semaglutide from other GLP-1 RAs can have better clinical and economic effects for patients with T2DM in China, indicating it as a dominant treatment choice.

Evaluating the Public Health and Health Economic Impacts of Baloxavir Marboxil and Oseltamivir for Influenza Pandemic Control in China: A Cost-Effectiveness Analysis Using a Linked Dynamic Transmission-Economic Evaluation Model.

Pandemic influenza poses a recurring threat to public health. Antiviral drugs are vital in combating influenza pandemics. Baloxavir marboxil (BXM) is a novel agent that provides clinical and public health benefits in influenza treatment. We constructed a linked dynamic transmission-economic evaluation model combining a modified susceptible-exposed-infected-recovered (SEIR) model and a decision tree model to evaluate the cost-effectiveness of adding BXM to oseltamivir in China's influenza pandemic scenario. The cost-effectiveness was evaluated for the general population from the Chinese healthcare system perspective, although the users of BXM and oseltamivir were influenza-infected persons. The SEIR model simulated the transmission dynamics, dividing the population into four compartments: susceptible, exposed, infected, and recovered, while the decision tree model assessed disease severity and costs. We utilized data from clinical trials and observational studies in the literature to parameterize the models. Costs were based on 2021 CN¥ and not discounted due to a short time-frame of one year in the model. One-way, two-way, and probabilistic sensitivity analyses were also conducted. The integrated model demonstrated that adding BXM to treatment choices reduced the cumulative incidence of infection from 49.49% to 43.26% and increased quality-adjusted life years (QALYs) by 0.00021 per person compared with oseltamivir alone in the base-case scenario. The intervention also amounted to a positive net monetary benefit of CN¥77.85 per person at the willingness to pay of CN¥80,976 per QALY. Sensitivity analysis confirmed the robustness of these findings, with consistent results across varied key parameters and assumptions. Adding BXM to treatment choices instead of only treating with oseltamivir for influenza pandemic control in China appears to be cost-effective compared with oseltamivir alone. The dual-agent strategy not only enhances population health outcomes and conserves resources, but also mitigates influenza transmission and alleviates healthcare burden.

First-line serplulimab plus chemotherapy versus chemotherapy in PD-L1-positive esophageal squamous-cell carcinoma: a cost-effectiveness analysis

Patients with PD-L1-positive esophageal squamous-cell carcinoma (ESCC) were significantly more likely to survive when treated with serplulimab plus cisplatin plus 5-fluorouracil (serplulimab-CF). At this point, it is unknown whether this expensive therapy is cost-effective. From the Chinese healthcare system's perspective, we aimed to evaluate serplulimab-CF versus CF alone for cost-effectiveness. A partitioned survival model was constructed based on the ASTRUM-007 trial. Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) were calculated. A further analysis of subgroups and scenarios was conducted. The willingness to pay (WTP) threshold of $38,258/QALY or $84,866/QALY is defined as three times the per capita gross domestic product value of the general region or affluent region. Compared with CF alone, in the overall (scenario 1), patients with PD-L1 expression level of 1 ≤ CPS < 10 (scenario 2), and patients with PD-L1 CPS ≥ 10 (scenario 3) populations, the ICERs were $69,025/QALY, $82,533/QALY, and $75,436/QALY for serplulimab-CF. Nevertheless, the probability of serplulimab-CF becoming cost-effective based on scenarios 1, 2, and 3 is only 2.71%, 0.94%, and 2.84%, respectively, at a WTP threshold of $38,258/QALY. When serplulimab costs < $4.84/mg, serplulimab-CF may be cost-effective at the WTP threshold of $38,258/QALY; otherwise, CF was preferred. Similar results were obtained from sensitivity analyses, suggesting the robustness of these findings. There was no cost-effectiveness in general regions of China for serplulimab-CF in PD-L1-positive ESCC compared to CF, although it is probably considered cost-effective in affluent regions. Serplulimab-CF may achieve favorable cost-effectiveness by lowering the price of serplulimab.

Comparison Between Sotorasib with Docetaxel for the Treatment of Chinese Patients with Previously Treated NSCLC with KRASG12C Mutation: A Cost-Effectiveness Analysis to Inform Drug Pricing.

This study sought to investigate the affordable price of sotorasib among patients with previously treated advanced KRASG12C-mutant non-small cell lung cancer (NSCLC) through a cost-effectiveness analysis from the perspectives of both the Chinese healthcare system and the patients. We developed a Markov model spanning a 20-year time horizon with a cycle length of 21 days. Our data were derived from the CodeBreaK 200 clinical trial, supplemented with published literature, publicly available national databases, and local hospitals. The primary outcomes were the affordable prices of sotorasib which would result in the incremental cost-effectiveness ratios (ICERs) of sotorasib relative to docetaxel below the preset willing-to-pay (WTP) threshold. Sensitivity analyses were performed to evaluate the model's robustness. At the national level, from the perspective of the Chinese healthcare system and patients, the price of sotorasib should be lower than US$0.04673 and $0.03231, respectively, to make it affordable, which is equivalent to $1346 and $931 per box (120mg × 240 pieces). At the provincial level, the price ceiling of sotorasib/mg fluctuated between $0.04084 to $0.08061 from the Chinese healthcare system's perspective and between $0.02642 to $0.06620 from the patients' perspective. Probabilistic sensitivity analyses revealed that, as the price of sotorasib decreased, its likelihood of being cost-effective increased. Sotorasib might be a cost-effective therapy in China. The pharmaco-economic evidence generated from this study has significant implications not only for guiding the drug pricing of the upcoming sotorasib but also for determining the reimbursement ratio for its potential inclusion in the National Reimbursement Drugs List in the future.

Cost-effectiveness of tislelizumab plus chemotherapy vs chemotherapy as first-line treatment of PD-L1 positive advanced gastric or gastroesophageal junction adenocarcinoma from a Chinese perspective

ABSTRACT Background This work was designed to assess the cost-effectiveness of front-line tislelizumab plus chemotherapy (TIS+Chemo) in advanced gastric cancer (GC) or gastroesophageal junction cancer (GEJC) with positive expression of programmed cell death ligand 1 (PD-L1) from the perspective of Chinese healthcare system. Research design and methods A 10-year partitioned survival model was undertaken utilizing clinical data from RATIONALE 305. Costs and utilities were both discounted at an annual rate of 5%. The primary outcome was incremental cost-effectiveness ratios (ICERs) and calculated as the cost per quality-adjusted life years (QALYs). The willingness-to-pay (WTP) threshold was set as $18,625/QALY. Only direct medical costs were considered. Sensitivity analyses and subgroup analyses were performed to evaluate the robustness of the model. Results In the base-case analysis, the incremental cost and effectiveness associated with TIS+Chemo vs Chemo was 7,361 and 0.38 QALYs, respectively, leading to an ICER of 19,371/QALY. At the WTP threshold of $18,625/QALY, the TIS+Chemo was not a cost-effective first-line treatment option. The model outcomes were robust. Conclusions TIS+Chemo did not provide a cost-effective approach for PD-L1 positive advanced GC/GEJC in China setting. However, TIS+Chemo might be cost-effective in provinces with higher WTP threshold. Clinical trial registration RATIONALE 305, www.clinicaltrials.gov, identifier is NCT03777657.

Cost-effectiveness of Kang Ai injection plus chemotherapy vs. Shenqi Fuzheng injection plus chemotherapy in the first-line treatment of advanced non-small cell lung cancer.

This study aimed to evaluate the cost-effectiveness of two Chinese patent medicines, including Kang Ai injection and Shenqi Fuzheng injection with each combined with platinum-based chemotherapy as the first-line treatment for patients with advanced non-small cell lung cancer (NSCLC) in China. From Chinese healthcare system perspective, a three state Markov model with a cycle of 3 weeks and a 10-year horizon was constructed to derive the incremental cost-effectiveness ratio (ICER). Since only individual patient data of progression-free survival (PFS) of Kang Ai injection group can be obtained, we extrapolated median overall survival (mOS) of Kang Ai injection group and median progression-free survival (mPFS) and mOS of Shenqi Fuzheng injection group based on published literature and methods. Then survival curves were estimated by the method of declining exponential approximation of life expectancy (DEALE), which is based on the assumption that survival follows a declining exponential function. We performed one-way sensitivity analysis and probabilistic sensitivity analysis to test the robustness. Additionally, a scenario analysis was adopted to investigate the impact of using best-fitting distribution for PFS curve of Kang Ai injection group on the economic conclusion. The base-case result indicated that Kang Ai injection group provided 0.217 incremental quality-adjusted life years (QALYs) at an incremental cost of $103.38 compared with Shenqi Fuzheng injection group. The ICER was $476.41/QALY, which was much lower than the willingness to pay threshold of one time the GDP per capita of China in 2022 ($12,070/QALY). Deterministic sensitivity analysis result showed that ICER was most sensitive to the changes in odds ratio (OR) value. The probabilistic sensitivity analysis confirmed the robustness of base-case analysis results. The scenario analysis result showed that by using Log-Normal distribution to fit the PFS curve of Kang Ai injection group and shortening the time horizon to 5 years, the ICER was $4,081.83/QALY, which was still much lower than the willingness to pay threshold. Kang Ai injection combined with platinum-based chemotherapy appeared to be more cost-effective for the treatment of advanced NSCLC than Shenqi Fuzheng injection combined with platinum-based chemotherapy.

Economic value of toripalimab plus axitinib as first-line treatment for advanced renal cell carcinoma in China: a model-based cost-effectiveness analysis

ABSTRACT Objective The current analysis aimed to evaluate the economic benefit of toripalimab plus axitinib for previously untreated RCC patients from the Chinese healthcare system perspective. Methods The partitioned survival model was developed to simulate 3-week patients’ transition in 20-year time horizon to evaluate the cost-effectiveness of toripalimab plus axitinib compared with sunitinib for advanced RCC. Survival data were gathered from the RENOTORCH trial, and cost and utility inputs were obtained from the database and published literature. Total cost, life-years (LYs), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) were the model outputs. Subgroup analyses and sensitivity analyses were conducted to increase the comprehensiveness and estimate the robustness of the model results. Results In the base-case analysis, compared with sunitinib, toripalimab plus axitinib could bring additional 1.19 LYs and 0.65 QALYs, with the marginal cost of $41,499.23, resulting in the ICER of $64,337.49/QALY, which is higher than the WTP threshold. And ICERs were always beyond the WTP threshold of all subgroups. Sensitivity analyses demonstrated the model results were robust. Conclusions Toripalimab plus axitinib was unlikely to be the cost-effective first-line therapy for patients with previously untreated advanced RCC compared with sunitinib from the Chinese healthcare system perspective.

Radiofrequency ablation using the ThermoCool SmartTouch Catheter guided by ablation index versus antiarrhythmic drugs in atrial fibrillation treatment in China: a cost-consequence analysis.

Aim: To evaluate the costs and consequences of two front-line atrial fibrillation (AF) treatments from Chinese healthcare system perspective: radiofrequency catheter ablation (RFCA) using ThermoCool SmartTouch Catheter guided by Ablation Index (STAI), in comparison to antiarrhythmic drugs (AADs). Patients & methods: We simulated clinical and economic consequences for AF patients initially receiving STAI or AADs using a short-term decision tree model leading to a 10-year long-term Markov model. The model projected both clinical consequences and costs associated with, among others, AF, heart failure (HF), strokes, and deaths due to AF or AF related complications. Data informing the models included combination of a local real-world study and published clinical studies. Results: STAI was advantageous versus AADs on all 4 main clinical outcomes evaluated; AF: 25.83% lower (12.84% vs 38.67%), HF: 2.22% lower (1.33% vs 3.55%), stroke or post stroke: 1.82% lower (10.00% vs 11.82%)and deaths due to AF or AF related complications: 0.64% lower (4.11% vs 4.75%). The average total cost per patient in STAI group was ¥16,682 lower (¥123,124 vs ¥139,806). The one-way sensitivity analysis indicated that the difference in total cost was most sensitive to annual AF recurrence probability in AADs-treated patients. Probabilistic sensitivity analysis indicated a 98.5% probability that RFCA treatment would result in cost savings by the end of the 10th year. Conclusion: Radiofrequency catheter ablation using SmartTouch catheter guided by Ablation Index was superior to AADs as the first-line AF treatment in Chinese setting with better clinical outcomes and at lower costs over a 10-year time horizon.
