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. Adv Ther 2024; 41:3159-3172. [PMID: 38888881 DOI: 10.1007/s12325-024-02908-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 05/20/2024] [Indexed: 06/20/2024]
Abstract
INTRODUCTION 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. METHODS 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. RESULTS 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 (120 mg × 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. CONCLUSION 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.

Abstract
Objective To determine the cost-effectiveness of imported immune checkpoint inhibitors (ICIs) such as atezolizumab and durvalumab, and domestic ICIs like serplulimab and adebrelimab, in combination with chemotherapy for extensive-stage small cell lung cancer (ES-SCLC) in China. Methods Using a 21-day cycle length and a 20-year time horizon, a Markov model was established to compare the clinical and economic outcomes of five first-line ICIs plus chemotherapy versus chemotherapy alone, as well as against each other, from the perspective of the Chinese healthcare system. Transition probabilities were estimated by combining the results of the CAPSTONE-1 trial and a published network meta-analysis. Cost and health state utilities were collected from multiple sources. Both cost and effectiveness outcomes were discounted at a rate of 5% annually. The primary model output was incremental cost-effectiveness ratios (ICERs). A series of sensitivity analyses were preformed to assess the robustness of the model. Results In the base-case analysis, the addition of first-line ICIs to chemotherapy resulted in the ICERs ranged from $80,425.31/QALY to $812,415.46/QALY, which exceeded the willing-to-pay threshold set for the model. When comparing these first-line immunochemotherapy strategies, serplulimab plus chemotherapy had the highest QALYs of 1.51286 and the second lowest costs of $60,519.52, making it is the most cost-effective strategy. Our subgroup-level analysis yielded results that are consistent with the base-case analysis. The sensitivity analysis results confirmed the validity and reliability of the model. Conclusion In China, the combination of fist-line ICIs plus chemotherapy were not considered cost-effective when compared to chemotherapy alone. However, when these fist-line immunochemotherapy strategies were compared with each other, first-line serplulimab plus chemotherapy consistently demonstrated superiority in terms of cost-effectiveness. Reducing the cost of serplulimab per 4.5 mg/kg would be a realistic step towards making first-line serplulimab plus chemotherapy more accessible and cost-effective.

Abstract
Background Lung cancer ranks first in both cancer incidence and mortality in China. The emergence of novel treatments for ALK-positive NSCLC led to an improvement in survival and quality of life for patients with advanced ALK mutation-positive non-small cell lung cancer (NSCLC). This study sought to assess the cost-effectiveness of 6 tyrosine kinase inhibitors (TKIs)-crizotinib, alectinib, ceritinib, brigatinib, ensartinib, and lorlatinib-as first-line treatments for ALK-positive NSCLC from the perspective of the Chinese health care system. Methods A Markov model was developed to estimate the cost-effectiveness of these 6 TKIs. In this model, ALK-positive NSCLC patients were initially simulated to receive 1 of the 6 TKIs as first-line therapy, followed by different TKIs as subsequent treatment and salvage chemotherapy as last-line treatment. Survival data were sourced from the latest published clinical trials. Costs were derived from recent national health insurance negotiations and hospital information systems of selected health care facilities. Utilities for healthy states and adverse events were obtained from the literature. One-way and probabilistic sensitivity analysis as well as scenario analysis was conducted to assess the robustness of the results. Results Compared to ensartinib, crizotinib, alectinib, ceritinib, brigatinib, and lorlatinib demonstrated incremental quality-adjusted life years (QALYs) of -1.13, 0.39, -0.58, -0.09, and 0.35, respectively. The corresponding incremental costs were $10 677, $33 501, -$6426, $2672, and $24 358. This resulted in ICERs of -$9449/QALY, $85 900/QALY, $11 079/QALY, $29 689/QALY and $69 594/QALY, respectively. Conclusion Crizotinib was considered to be absolutely dominated by ensartinib. Under a willingness-to-pay threshold of $38 223/QALY, ceritinib and brigatinib were cost-effective compared with ensartinib, while lorlatinib and alectinib were not cost-effective when compared with ensartinib. Overall, brigatinib emerged as the most cost-effective treatment among all the options considered.

Abstract
Objective To estimate the cost-effectiveness of adding serplulimab to chemotherapy for metastatic squamous non-small cell lung cancer (NSCLC) patients in a first-line setting from a Chinese perspective. Methods A three-health state partitioned survival model was constructed to simulate disease development. The clinical data used in the model were derived from the ASTRUM-004 clinical trial. Only direct medical costs were included, and the utilities were derived from published literature. The quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) were employed to evaluate health outcomes. Additionally, a sensitivity analysis was performed to verify the robustness of the results. Results Compared with chemotherapy alone, the addition of serplulimab resulted in an increase of 0.63 QALYs with an incremental cost of $5,372.73, leading to an ICER of $8,528.14 per QALY. This ICER was significantly lower than 3 times China's per capita GDP. The one-way sensitivity analysis suggested that the utility of PFS was the most sensitive factor on ICERs, followed by the price of serplulimab. Conclusion The combination of serplulimab and chemotherapy has been shown to be a cost-effective initial treatment option for patients with metastatic squamous NSCLC with the commonly accepted willingness-to-pay threshold of 3 times the GDP per capita per QALY in China.

Abstract
INTRODUCTION The updated ORIENT-11 study demonstrated that sintilimab, when combined with chemotherapy, had promising survival advantage compared to standard chemotherapy alone in the first-line treatment for previously untreated, locally advanced or metastatic non-squamous non-small cell lung cancer (nsNSCLC). This study aims to evaluate the cost-effectiveness of sintilimab plus chemotherapy for advanced nsNSCLC from a Chinese societal perspective. METHODS A partitioned survival model with a embedded decision tree was developed to assess the economic value of sintilimab plus chemotherapy over a lifetime horizon. Clinical data was captured from the updated ORIENT-11 study, while costs, health productivity losses, and utility values were collected from a nationwide cross-sectional survey in tertiary hospitals across multiple provinces in China. The primary outcomes were measured using the metrics of quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICER). Costs and health outcomes were discounted at an annual rate of 5% per annum. Sensitivity analyses, including one-way and probabilistic sensitivity analyses, subgroup analyses, and scenario analyses, were performed. RESULTS Compared to standard chemotherapy, treatment with sintilimab plus chemotherapy incurred a mean total cost of $23,979 and gained 0.98 QALYs over the lifetime horizon, resulting in an ICER of $24,568 per QALY gained. The use of sintilimab accumulated direct non-medical costs of $9262 and indirect costs of $6780 over 16 years. Probabilistic sensitivity analyses showed an 84.2% probability of sintilimab plus chemotherapy being cost-effective at a threshold of three times China's per capita gross domestic product in 2022 ($38,201). The model was most sensitive to the discount rate of QALYs and costs, as well as the costs of pemetrexed, sintilimab, and subsequent therapy in progressive disease state. Subgroup analyses indicated favorable incremental net monetary benefits in all subgroups. CONCLUSION Sintilimab plus chemotherapy is a cost-effective first-line treatment therapy for advanced nsNSCLC in China when compared to standard chemotherapy. These findings, along with the improved progression-free survival and overall survival (OS) observed in ORIENT-11, support the use of this regimen in eligible candidates for advanced nsNSCLC.

Abstract
PURPOSE Quality-adjusted life-year (QALY) is a dominant measurement of health gain in economic evaluations for pricing drugs. However, end-of-life (EoL) patients' preference for QALY gains in life expectancy (LE) and quality of life (QoL) during different disease stages remains unknown and is seldom involved in decision-making. This study aims to measure preferences and willingness-to-pay (WTP) towards different types of QALY gain among EoL cancer patients. METHODS We attributed QALY gain to four types, gain in LE and QoL, respectively, and during both progression-free survival (PFS) and post-progression survival (PPS). A discrete choice experiment including five attributes (the four QALY attributes and one cost attribute) with three levels each was developed and conducted with 85 Chinese advanced non-small cell lung cancer patients in 2022. All levels were set with QALY gain/cost synthesised from research on anti-lung cancer drugs recently listed by Chinese National Healthcare Security Administration. Each respondent answered six choice tasks in a face-to-face interview. The data were analysed using mixed logit models. RESULTS Patients valued LE-related QALY gain in PFS most, with a relative importance of 81.8% and a WTP of $43,160 [95% CI 26,751 ~ 59,569] per QALY gain. Respondents consistently preferred LE-related to QoL-related QALY gain regardless of disease stage. Patients with higher income or lower education levels tended to pay more for QoL-related QALY gain. CONCLUSION Our findings suggest a prioritised resource allocation to EoL-prolonging health technologies. Given the small sample size and large individual heterogeneity, a full-scale study is needed to provide more robust results.

Abstract
PURPOSE Patients with advanced non-small cell lung cancer (NSCLC) mostly receive essential routine care and support from informal caregivers, who usually experience poorer health-related quality of life (HRQoL). The study aimed to evaluate the HRQoL and its predictors among informal caregivers of patients with advanced NSCLC in China. METHODS We interviewed the adult caregiver population of patients with advanced NSCLC (stage IIIB~IV) in nine tertiary hospitals from multiple provinces in China between November 2020 and June 2021. The EQ-5D-5L instrument measured the HRQoL of caregivers, as analyzed by employing descriptive analysis, univariate analysis, Tobit regression, and multivariate logistic regression, and investigated the important influencing factors further. RESULTS A valid sample of 553 caregivers was analyzed. The mean EQ-5D-5L utility score of caregivers was 0.92 (SD = 0.14). Caregivers reported the greatest problems in mental health, with 45.39% reporting slight, moderate, severe, or extreme anxiety/depression. The potential influencing factors of HRQoL in caregivers included patients' age and cancer histology, relationship with the patients, and daily caregiving hours. Compared to other caregivers, patients' spouses had the lowest HRQoL. In addition, over six hours of caregiving per day was associated with lower HRQoL in caregivers of patients with advanced NSCLC. CONCLUSIONS The HRQoL of caregivers for patients with advanced NSCLC was investigated for the first time in China. The informal caregivers experience decreased HRQoL, with anxiety /depression problems being reported the most. The findings of this study would provide extensive information on the HRQoL of advanced NSCLC patients' caregivers for future health-promoting self-care.

BioDrugs 2024; 38:157-170. [PMID: 37792142 DOI: 10.1007/s40259-023-00628-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/18/2023] [Indexed: 10/05/2023]
Abstract
BACKGROUND On the basis of immunohistochemistry PD-L1 testing results, patients with advanced non-small cell lung cancer (NSCLC) are treated differently. Theoretically, patients with high PD-L1 expression (50% or 1%) should receive PD-1 monotherapy for fewer adverse reactions and cost savings from avoiding chemotherapy; however, there is controversy surrounding the cut-off criteria (1% or 50%) for immunohistochemistry testing and threshold for PD-1 monotherapy. OBJECTIVE This study aims to predict the effectiveness and cost-effectiveness of different immunotherapy strategies for patients with NSCLC in China from the healthcare system perspective. PATIENTS AND METHODS A microsimulation model was developed to evaluate the effectiveness and cost-effectiveness of three treatment strategies: PD-L1 testing (1%) (PD-1 monotherapy for those with PD-L1 expression at 1% threshold, and combination with chemotherapy for others with immunohistochemistry testing), PD-L1 testing (50%) (PD-1 monotherapy for those with PD-L1 expression at 50% threshold, and combination with chemotherapy for others with immunohistochemistry testing), and No PD-L1 testing (PD-1 combined with chemotherapy without immunohistochemistry testing). The model assumed 1000 patients per strategy, with each patient entering a unique clinical path prior to receiving treatment on the basis of PD-L1 test results. Clinical inputs were derived from clinical trials. Cost and utility parameters were obtained from the database and literature. One-way probabilistic sensitivity analyses (PSA) and six scenario analyses were used to test the model's robustness. RESULTS The study revealed a hierarchy of survival benefits across three strategies, with No PD-L1 testing demonstrating the most survival advantage, followed by PD-L1 testing (50%), and finally, PD-L1 testing (1%). The comparative analysis demonstrated that No PD-L1 testing significantly enhanced overall survival (OS) (HR 0.85, 95% CI 0.78-0.93), progression-free survival (HR 0.82, 95% CI 0.75-0.90), and progression-free2 survival (PFS2) (HR 0.91, 95% CI 0.83-0.99) when juxtaposed against PD-L1 testing (1%). However, these improvements were not as pronounced when compared with PD-L1 testing (50%), particularly in relation to PFS, PFS2, and OS. The cost-effectiveness analysis further unveiled incremental cost-utility ratios (ICUR), with No PD-L1 testing versus PD-L1 testing (50%) at $34,003 per quality-adjusted life year (QALY) and No PD-L1 testing versus PD-L1 testing (1%) at $34,804 per QALY. In parallel, the ICUR for PD-L1 testing (50%) versus PD-L1 testing (1%) stood at $35,713 per QALY. Remarkably, the PSA result under a willingness-to-pay (WTP) threshold of $10,144 per QALY, with a 100% probability, demonstrated PD-L1 testing (1%) as the most cost-effective option. CONCLUSIONS The survival benefits of PD-1 monotherapy for high expression with PD-L1 immunohistochemistry testing are inferior to those of PD-1 combined with chemotherapy without testing, but it is found to be more cost-effective at the WTP thresholds in China and holds great potential in increasing affordability and reducing the economic burden.

Sotorasib versus Docetaxel for treatment of US and Chinese patients with advanced non-small-cell lung cancer with KRAS p.G12C-mutated: A cost-effectiveness analysis to inform drug pricing. Medicine (Baltimore) 2023; 102:e36387. [PMID: 38115313 PMCID: PMC10727560 DOI: 10.1097/md.0000000000036387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/08/2023] [Accepted: 11/09/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND The cost-effectiveness of sotorasib and its reasonable price in the United States (US) and China remain unknown. Our objective was to estimate the price at which sotorasib could be economical as second-line treatment for advanced non-small-cell lung cancer patients with Kirsten rat sarcoma viral oncogene homolog p.G12C-mutation in 2 countries. METHODS We conducted an economic evaluation from the perspective of US and Chinese payers. To analyze US patients, we built a partitioned survival model. However, since we lacked Asian-specific overall survival data, we created a state transition model for the Chinese patients. We obtained patients' baseline characteristics and clinical data from CodeBreaK200, while utilities and costs were gathered from public databases and published literature. We calculated costs (US dollar), life years, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios. We conducted price simulation to guide pricing strategies. Additionally, we assessed the reliability of our results through sensitivity analyses, scenario analyses, and subgroup analyses. RESULTS The incremental cost-effectiveness ratios of sotorasib compared to docetaxel were $1501,852 per quality-adjusted life-years (QALY) in the US and $469,106/QALY in China, respectively, which meant sotorasib was unlikely to be economical at the currently available price of $20,878 (240 × 120 mg) in both countries. Price simulation results revealed that sotorasib would be preferred at a price lower than $1400 at the willingness-to-pay threshold of $37,376 in China and a price lower than $2220 at the willingness-to-pay threshold of $150,000 in the US. Sensitivity, scenario, and subgroup analyses showed that these conclusions were generally robust, the model was most sensitive to the utilities of progression-free survival and post-progression survival. CONCLUSIONS Sotorasib could potentially be a cost-effective therapy in the US and China following price reductions. Our evidence-based pricing strategy can assist decision-makers and clinicians in making optimal decisions. However, further analysis of budget impact and affordability is needed.

Risk Manag Healthc Policy 2023; 16:2521-2529. [PMID: 38024490 PMCID: PMC10680037 DOI: 10.2147/rmhp.s439119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 11/15/2023] [Indexed: 12/01/2023] Open
Abstract
Purpose The market price of adebrelimab, the first Chinese-developed anti-PD-L1 antibody used as a first-line treatment for extensive stage-small-cell lung cancer (ES-SCLC), has garnered significant public attention. This study sought to investigate the affordable price of adebrelimab for Chinese patients with untreated ES-SCLC through a cost-effectiveness analysis. Patients and Methods We conducted a cost-effectiveness analysis using a Markov model, incorporating a what-if scenario of adding adebrelimab to first-line etoposide/platinum (EP) chemotherapy is cost-effective for ES-SCLC patients from the perspective of the Chinese healthcare system. The model included three mutually exclusive health states, with transition probabilities derived from the CAPSTONE-1 trial. Health state utilities and costs were acquired from a myriad of authoritative sources. We compared the incremental cost-effectiveness ratios (ICERs) for adebrelimab plus EP chemotherapy (AEP) versus EP with a willingness-to-pay threshold of $37,654 per quality-adjusted life-years (QALYs) to estimate the affordable price ceiling of the upcoming adebrelimab. Results For the entire ES-SCLC population, the estimated price ceiling of adebrelimab/mg was $0.542 (95% CI, $0.542-$0.552). Subgroup analyses found that the highest price ceiling of adebrelimab/mg was observed in ES-SCLC patients with lactate dehydrogenase concentration ≤ upper normal limit [$0.824 (95% CI, $0.815-$0.830)]; and the lowest was found in ES-SCLC patients with liver metastasis [$0.252 (95% CI, $0.250- $0.256)]. Sensitivity analysis revealed a heightened probability of cost-effectiveness for the first-line AEP as the price of adebrelimab decreased, encompassing both the entire ES-SCLC population and its subgroups. Conclusion The affordable price range for adebrelimab/mg Chinese patients with untreated ES-SCLC was estimated to be between $0.252 and $0.824, with variations observed across different subgroups. In the context of universal healthcare coverage, our study provides valuable evidence to inform the implementation of a value-based pricing strategy for cancer treatment.

Abstract
OBJECTIVES Monetizing health has sparked controversy and has implications for pricing strategies of emerging health technologies. Medical insurance payers typically set up thresholds for quality-adjusted life years (QALY) gains based on health productivity and budget affordability, but they rarely consider patient willingness-to-pay (WTP). Our study aims to compare Chinese payer threshold and patient WTP toward QALY gain of advanced non-small cell lung cancer (NSCLC) and to inform a potential inclusion of patient WTP under more complex decision-making scenarios. METHODS A regression model was constructed with cost as the independent variable and QALY as the dependent variable, where the regression coefficients reflect mean opportunity cost, and by transforming these coefficients, the payer threshold can be obtained. Patient WTP was elicited through a contingent valuation method survey. The robustness of the findings was examined through sensitivity analyses of model parameters and patient heterogeneity. RESULTS The payer mean threshold in the base-case was estimated at 150,962 yuan (1.86 times per capita GDP, 95% CI 144,041-159,204). The two scenarios analysis generated by different utility inputs yielded thresholds of 112,324 yuan (1.39 times per capita GDP) and 111,824 yuan (1.38 times per capita GDP), respectively. The survey included 85 patients, with a mean WTP of 148,443 yuan (1.83 times per capita GDP, 95% CI 120,994-175,893) and median value was 106,667 yuan (1.32 times the GDP per capita). Due to the substantial degree of dispersion, the median was more representative. The payer threshold was found to have a high probability (98.5%) of falling within the range of 1-2 times per capita GDP, while the robustness of patient WTP was relatively weak. CONCLUSIONS In China, a country with a copayment system, payer threshold was higher than patient WTP, indicating that medical insurance holds significant decision-making authority, thus temporarily negating the need to consider patient WTP.

Abstract
INTRODUCTION This study examined the cost-effectiveness of first-line toripalimab plus chemotherapy (TC) for patients with advanced non-small cell lung cancer (NSCLC), excluding patients with nonsquamous NSCLC and EGFR/ALK mutations. It further analyzed the cost-effectiveness of this strategy in biomarker-based subgroups, all within the context of the Chinese healthcare system. METHODS Eighteen Markov models with 21-day Markov cycle lengths and 30-year time horizons were constructed in this study. Clinical effectiveness data were derived from the CHOICE-01 trial. Health state utilities and costs data were obtained from various sources. The primary outputs were the calculation of incremental cost-effectiveness ratios (ICERs), which were then compared to a willingness-to-pay (WTP) threshold of $17,961 per quality-adjusted life-year (QALY). This comparison was used to determine the treatment that offered greater cost-effectiveness. To account for uncertainty in the model, sensitivity analyses were conducted. RESULTS For the overall patient population, the estimated ICER between first-line TC and placebo plus chemotherapy (PC) was $9445/QALY, significantly lower than the WTP threshold used in the model. In subgroups based on pathologic types, first-line TC had an ICER of $16,757/QALY for patients with nonsquamous NSCLC, slightly below the WTP threshold; first-line TC demonstrated dominance in patients with squamous NSCLC, indicating both better effectiveness and lower costs compared to first-line PC. In biomarkers-based subgroups, first-line TC was dominant over first-line PC in the subgroups with programmed cell death ligand 1 (PD-L1) expression ≥ 50% and SMARCA4 mutations. Moreover, first-line TC had ICERs lower than the WTP threshold in other subgroups, except for the subgroup with RB1 mutations. Sensitivity analysis confirmed the robustness of these findings. CONCLUSION From the perspective of the Chinese healthcare system, this study's findings suggested that first-line TC represents a cost-effective strategy for patients with advanced NSCLC. However, the cost-effectiveness of first-line TC varied across different subgroups when considering predictive biomarkers.

Abstract
INTRODUCTION Sugemalimab is the first China-developed programmed death-ligand 1 inhibitor that has proved to be effective as a first-line treatment for both metastatic squamous and non-squamous non-small cell lung cancer (NSCLC) when used in combination with chemotherapy. This study compared the cost-effectiveness of sugemalimab plus chemotherapy (sugema + chemo) with placebo plus chemotherapy (placebo + chemo) among metastatic squamous and nonsquamous NSCLC, respectively. METHODS Separate Markov models were constructed to generate the cumulative healthcare costs and quality-adjusted life-years (QALYs) associated with two treatment strategies over a 20-year time horizon. Transition probabilities were estimated using survival data reported in the GEMSTONE-302 trial. Health state utilities and costs were derived from published literature, national databases, and local general hospitals. Sensitivity analyses were performed to test the robustness of our conclusions. RESULTS Compared with first-line placebo + chem, sugema + chemo achieved an incremental cost-effectiveness ratio (ICER) of $57,842/QALY for patients with metastatic squamous NSCLC and achieved an ICER of $78,249/QALY for patients with metastatic non-squamous NSCLC. In our sensitivity analyses of a willingness-to-pay (WTP) threshold of $35,663 per QALY, the first-line sugema + chemo was only cost-effective for patient groups when the price of sugemalimab decreased. CONCLUSION Sugema + chemo was not cost-effective as a first-line treatment for either metastatic squamous or metastatic nonsquamous NSCLC in Chinese patients compared with placebo + chemo. However, we found that sugema + chemo would be cost-effective in patients with metastatic squamous and non-squamous NSCLC when sugemalimab's price was decreased by > 39.0% and 64.8%, respectively.

Abstract
Purpose The five-year update data from the KEYNOTE-407 study have unveiled noteworthy improvements in survival outcomes achieved with pembrolizumab plus chemotherapy (Pembro+Chemo) compared to placebo plus chemotherapy (Placebo+Chemo) for patients with previously untreated metastatic squamous non-small cell lung cancer (NSCLC). Building upon this finding, our study sought to evaluate the cost-effectiveness of Pembro+Chemo, utilizing the latest available data, from the perspective of the Chinese health care system. Patients and Methods A Markov model was employed to compare the quality-adjusted life-year (QALY), life-year (LY), total cost, and incremental cost-effectiveness ratio (ICER) between Pembro+Chemo and Placebo+Chemo. The clinical and safety data were derived from the five-year update date of the KEYNOTE-407 study. Sensitivity analyses were conducted to assess the uncertainty of the model, and additional subgroup analyses were performed to explore specific subpopulations. Results For patients with previously untreated metastatic squamous NSCLC, the utilization of Pembro+Chemo resulted in a improvement of 0.61 quality-adjusted life years (QALYs) along with a cost reduction of $17,491.52 when compared to Placebo+Chemo. Notably, across various subgroups with different tumor proportion scores (TPS), Pembro+Chemo demonstrated enhanced QALYs and lower total costs. Conclusion From the perspective of the Chinese health care system, first-line Pembro+Chemo emerges as a dominant treatment option over Placebo+Chemo for the treatment of metastatic squamous NSCLC.

Abstract
BackgroundAtezolizumab may provide clinical benefits to patients with advanced non-small cell lung cancer (NSCLC). However, the price of atezolizumab is relatively high, and its economic outcomes have remained unclear. In this study, we used two models to examine the cost-effectiveness of initial atezolizumab monotherapy versus chemotherapy for patients with PD-L1 high-expressing EGFR and ALK wild-type advanced NSCLC in the context of the Chinese healthcare system.MethodsPartitioned Survival model and Markov model were performed to evaluate the cost-effectiveness of first-line single-agent atezolizumab versus platinum-based chemotherapy for patients with advanced NSCLC with PD-L1 high-expressing EGFR and ALK wild-type disease. Clinical outcomes and safety information were obtained from the most recent data from the IMpower110 trial, while cost and utility values were obtained from Chinese hospitals and relevant literature. Total costs, life years (LYs), quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were estimated. One-way and probabilistic sensitivity analyses were performed to explore model uncertainty. Scenario analyses were also conducted for the Patient Assistance Program (PAP) and various provinces in China.ResultsIn the Partitioned Survival model, the total cost of atezolizumab was $145,038, providing 2.92 LYs and 2.39 QALYs, while the total cost of chemotherapy was $69,803, providing 2.12 LYs and 1.65 QALYs. The ICER for atezolizumab versus chemotherapy was $102,424.83/QALY; in the Markov model, the ICER was $104,806.71/QALY. Atezolizumab was not cost-effective at the WTP threshold of three times China’s per capita gross domestic product (GDP). Sensitivity analysis showed that the cost of atezolizumab, the utility of PFS, and the discount rate had a significant impact on ICER; PAP significantly reduced ICER, but atezolizumab was still not cost-effective in China.ConclusionFirst-line monotherapy with atezolizumab for patients with PD-L1 high-expressing EGFR and ALK wild-type advanced NSCLC was estimated to be less cost-effective than chemotherapy in terms of the Chinese healthcare system; offering PAP increased the likelihood that atezolizumab would be cost-effective. In some areas of China with higher levels of economic development, atezolizumab was likely to be cost-effective. To improve the cost-effectiveness of atezolizumab, drug prices would need to be reduced.

Abstract
OBJECTIVES First-line treatment with nivolumab plus ipilimumab has been shown to improve overall survival (OS) and progression-free survival (PFS) for patients with advanced non-small cell lung cancer (NSCLC). The current study evaluated the cost-effectiveness of nivolumab plus ipilimumab versus chemotherapy in advanced NSCLC from the perspective of Chinese healthcare system. METHODS A three state-transition Markov model was employed to evaluate the cost and effectiveness of nivolumab plus ipilimumab versus chemotherapy in the first-line treatment of advanced NSCLC. Key clinical data in the model were derived from Part 1 of the phase 3 CheckMate 227 trial (NCT02477826). Costs and utilities were obtained from published literatures. The main endpoints of the model were costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were performed to assess the model uncertainty. RESULTS Nivolumab plus ipilimumab was associated with an increase in overall cost of $95,867.82 and improved effectiveness of 0.98 QALYs compared with chemotherapy, yielding an ICER of $97,676.24 per QALY. In one-way sensitivity analysis, the variables that had the greatest influence on the ICER were hazard ratio for OS and body weight. In probabilistic analysis, nivolumab plus ipilimumab had a 0% probability of being cost-effective at a willingness-to-pay (WTP) threshold of $37,663.26/QALY in China. However, the combination therapy would become cost-effective when the cost of nivolumab and ipilimumab were discounted by 65%. CONCLUSION First-line nivolumab plus ipilimumab treatment for advanced NSCLC was found to be not cost-effective compared with chemotherapy at a WTP threshold of $37,663.26/QALY in China.

Effectiveness and cost-effectiveness analysis of 11 treatment paths, seven first-line and three second-line treatments for Chinese patients with advanced wild-type squamous non-small cell lung cancer: A sequential model. Front Public Health 2023; 11:1051484. [PMID: 36908446 PMCID: PMC9999022 DOI: 10.3389/fpubh.2023.1051484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 02/08/2023] [Indexed: 02/26/2023] Open
Abstract
Background A total of 11 treatment sequences for advanced wild-type squamous non-small cell lung cancer are recommended by Chinese Society of Clinical Oncology Guidelines, consisting of seven first-line and three second-line treatments. Five of these treatments were newly approved in China between 2021 and 2022. We evaluated the effectiveness and cost-effectiveness of these strategies from the Chinese healthcare system perspective. Methods Network meta-analysis with non-proportional hazards was used to calculate the relative efficacy between interventions. A sequential model was developed to estimate costs and quality-adjusted life years (QALY) for treatment sequences with first-line platinum- and paclitaxel-based chemotherapy (SC) with or without nedaplatin, tislelizumab, camrelizumab, sintilimab, sugemalimab or pembrolizumab, followed by second-line docetaxel, tislelizumab or nivolumab. SC and docetaxel were used as comparators for first-line and second-line treatments, respectively. QALY and incremental cost-effectiveness ratio (ICER) were used to evaluate effectiveness and cost-effectiveness, respectively. Cost-effective threshold was set as USD 19,091. Subgroup analysis was conducted to determine the best first-line and second-line therapy. Results Pembrolizumab + SC, followed by docetaxel (PED) was the most effective treatment sequence. QALYs for patients received SC, nedaplatin + SC, tislelizumab + SC, sintilimab + SC, camrelizumab + SC, sugemalimab + SC, pembrolizumab + SC followed by docetaxel were 0.866, 0.906, 1.179, 1.266, 1.179, 1.266, 1.603, 1.721, 1.807; QALYs for SC, nedaplatin + SC followed by tislelizumab were 1.283, 1.301; QALYs for SC, nedaplatin + SC followed by nivolumab were 1.353, 1.389. Camrelizumab + SC, followed by docetaxel (CAD) was the most cost-effective. Compared to SC with or without nedaplatin, tislelizumab, or sintilimab followed by docetaxel, ICERs of CAD were USD 12,276, 13,210, 6,974, 9,421/QALY, respectively. Compared with nedaplatin or SC followed by tislelizumab, the ICERs of CAD were USD 4,183, 2,804/QALY; CAD was dominant compared with nedaplatin or SC followed by nivolumab; The ICER of sugemalimab + SC followed by docetaxel and PED were USD 522,023, 481,639/QALY compared with CAD. Pembrolizumab + SC and camrelizumab + SC were the most effective and cost-effective first-line options, respectively; tislelizumab was the most effective and cost-effective second-line therapy. Tislelizumab used in second-line was more effective than first-line, no significant differences between their cost-effectiveness. Sensitivity and scenario analysis confirmed robustness of the results. Conclusions PED and CAD are the most effective and cost-effective treatment sequence, respectively; pembrolizumab + SC and camrelizumab + SC are the most effective and cost-effective first-line choice, respectively; tislelizumab is the most effective and cost-effective second-line choice.

Measuring direct non-medical burden among patients with advanced non-small cell lung cancer in China: is there a difference in health status? Front Public Health 2023; 11:1090623. [PMID: 37213608 PMCID: PMC10192575 DOI: 10.3389/fpubh.2023.1090623] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 04/06/2023] [Indexed: 05/23/2023] Open
Abstract
Objective This study was conducted to estimate the direct non-medical cost of advanced non-small cell lung cancer (NSCLC) patients and explore whether its associated factors vary by health status. Methods Data were obtained from 13 centers in five provinces for patients with advanced NSCLC in China. The direct non-medical cost of patients since the patients were diagnosed with NSCLC included the cost of transportation, accommodation, meal, hired caregiving, and nutrition. We measured patients' health status by EQ-5D-5L instrument and divided them into good (≥0.75) and poor (<0.75) groups based on the utility score. A generalized linear model (GLM) was used to assess independent associations between statistically significant factors and non-medical financial burden in health status subgroups. Results Data from 607 patients were analyzed. The direct non-medical cost associated with advanced NSCLC since diagnosis was $2,951 per case ($4,060 in the poor health group and $2,505 in the other), with nutrition costing the most. GLM results showed that residence(Urban area vs. Rural area: -1.038, [-2.056, -0.02]), caregivers' occupation type (Farmer vs. Employee: -1.303, [-2.514, -0.093]), hospitalization frequency (0.077, [0.033, 0.12]), average length of hospital stay (0.101, [0.032, 0.17]), and pathological type (Squamous carcinoma vs. Non-squamous carcinoma: -0.852, [-1.607, -0.097]) were independent factors influencing direct non-medical cost in the poor health group. Among participants with good health status, residence (Urban area vs. Rural area: -0.621, [-1.005, -0.236]), marital status (Others vs. Married: 0.762, [0.035, 1.488]), patients' employment status, current caregiving time per day (more than 9 hours per day vs. less than 3 hours per day: 0.471, [0.134, 0.807]), duration of disease (0.015, [0.007, 0.024]), and hospitalization frequency (0.091, [0.068, 0.113]) were statistically associated factors. Conclusion The direct non-medical economic burden of advanced NSCLC patients in China is considerable and differs by health status. Strengthening accessibility for more effective therapies and early nutritional intervention to improve prognosis, and further promoting accessible care forms within relevant healthcare insurance coverage may be potentially feasible approaches to alleviate the direct non-medical economic burden for patients and their families.

Abstract
BACKGROUND Programmed cell death protein-1/programmed cell death ligand-1 (PD-1/L1) inhibitor is a promising therapeutic option that can be used as either a first-line or second-line treatment for driver-negative advanced or metastatic squamous non-small cell lung cancers (sqNSCLC). However, reuse of PD-1/L1 inhibitor in second-line beyond progression after the first-line is generally not recommended. Therefore, oncologists face challenges in making a proper decision of using PD-1/L1 inhibitor. This analysis aimed to determine whether it is more cost-effective to use sintilimab, a domestic anti-PD-1 drug in China, as a first-line treatment than reserving it until second-line. METHODS We conducted a cost-effectiveness analysis to compare the use of sintilimab in the first-line setting with reserving its use until the second-line for driver-negative advanced or metastatic sqNSCLC from the perspective of the Chinese healthcare system. A Markov model composed of five main mutually independent health states and three temporary health states was established to simulate patients' clinical trajectory. Transition probabilities, including disease progression, survival, and adverse events-related treatment discontinuation, were estimated using data from the ORIENT-12, ORIENT-3, and ALTER0303 clinical trials. The robustness of the model was assessed using deterministic sensitivity analysis (DSA) and probabilistic sensitivity analyses. RESULTS Reserving the use of sintilimab until the second-line was associated with a greater effectiveness (1.52 vs. 1.37 quality-adjusted life-years [QALYs]) and a higher healthcare cost ($12,203 vs. $14,045) compared with the first-line sintilimab, resulting in an incremental cost-effectiveness ratio (ICER) of $12,693 per QALY. The results of DSA suggested that variations in all parameters did not result in the ICERs surpassing the willingness-to-pay threshold of $35,663/QALY. CONCLUSIONS For Chinese patients with driver-negative advanced or metastatic sqNSCLC, reserving the use of sintilimab until the second-line represents a cost-effective treatment strategy compared with the first-line treatment. This finding is useful to inform Chinese healthcare policymakers regarding the optimized treatment strategies of use of domestic PD-1/L1 inhibitors sintilimab.

Front Oncol 2022; 12:833773. [DOI: 10.3389/fonc.2022.833773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Accepted: 09/30/2022] [Indexed: 12/24/2022] Open
Abstract
BackgroundA recently overall survival (OS) analysis from the AURA3 trial indicated that osimertinib improves median OS versus platinum-pemetrexed for patients with previously treated epidermal growth factor receptor (EGFR) T790M advanced non-small cell lung cancer (NSCLC). Here, we assessed the cost-effectiveness of second-line osimertinib versus platinum-pemetrexed, from the perspectives of the United States payer and the Chinese health care system.MethodsA Markov model was constructed to compare the costs and health outcomes of osimertinib versus platinum-pemetrexed in second-line treatment of EGFR T790M advanced NSCLC. Life years (LYs), quality adjusted life years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs) were calculated. One-way and probabilistic sensitivity analyses assessed the robustness of the model. Cost-effectiveness was examined in the intention-to-treat (ITT) population and central nervous system (CNS) metastases population.ResultsIn the United States, compared with platinum-pemetrexed, osimertinib yielded additional effectiveness of 0.43 QALYs and -0.12 QALYs, with incremental costs of $67,588 and $16,465 in the ITT population and CNS metastases population, respectively. The ICERs of osimertinib over platinum-pemetrexed were $159,126/QALY and $-130,830/QALY, respectively. The probability of osimertinib being cost-effective was 37% and 5.76%, respectively, at the willingness-to-pay (WTP) threshold of $150,000/QALY. In China, osimertinib showed incremental effectiveness of 0.34 QALYs and -0.14 QALYs, with incremental costs of $1,663 and $-505, resulting in ICERs of $4,950/QALY and $3,754/QALY in the ITT population and CNS metastases population, respectively. At the WTP threshold of $37,489/QALY, there was a 100% and 26% likelihood that osimertinib was cost-effective in the ITT population and CNS metastases population.ConclusionIn the United States, second-line osimertinib treatment for EGFR T790M advanced NSCLC is not cost-effective compared to platinum-pemetrexed under the current WTP threshold. When the osimertinib price reduces, the economic outcome may become favorable. In China, assuming a WTP threshold of $37,489/QALY, osimertinib is the dominant treatment strategy compared with platinum-pemetrexed in the ITT population and provides cost savings for CNS metastases patients.

Front Public Health 2022; 10:985834. [PMID: 36211665 PMCID: PMC9533130 DOI: 10.3389/fpubh.2022.985834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 09/05/2022] [Indexed: 01/25/2023] Open
Abstract
Objective Six anaplastic lymphoma kinase-tyrosine kinase inhibitors (ALK-TKIs), including one domestic (ensartinib) and five imported ALK-TKIs (crizotinib, ceritinib, alectinib, brigatinib, and lorlatinib), have been recommended as first-line treatments for advanced ALK-positive NSCLC in China. This study sought to examine the cost-effectiveness of these six novel therapies in Chinese patients. Material and methods We constructed a Markov model to compare the cost-effectiveness of the six ALK-TKIs as a first-line treatment for patients with advanced ALK-positive NSCLC from the perspective of the Chinese healthcare system. Transition probabilities were estimated by synthesizing data from the PROFILE 1,029 trial and a network meta-analysis. Health state utilities and costs were sourced from published literature, publicly available national databases, and local general hospitals. The robustness of model was assessed via deterministic sensitivity analyses and probabilistic sensitivity analyses. Results Compared with crizotinib, ensartinib achieved additional 0.12 quality-adjusted life-year (QALY) with marginal costs of $3,249, resulting in an incremental cost-effectiveness ratio (ICER) of $27,553/ QALY. When compared with ceritinib and brigatinib, ensartinib achieved additional 0.06 and 0.03 QALYs with substantially reduced costs. When compared with lorlatinib and alectinib, ensartinib was associated with a lower QALY and decreased total costs; the ICERs for lorlatinib and alectinib were $934,101/ QALY and $164,888/ QALY, respectively. Conclusion For Chinese patients with advanced ALK-positive NSCLC, ensartinib was a cost-effective option compared with crizotinib, and was a dominant alternative to ceritinib and brigatinib. Although lorlatinib and alectinib were associated with prolonged survival compared with ensartinib, they were less cost-effective than ensartinib due to the overwhelming total costs.

Abstract
Objective: Domestic PD-1inhibitor tislelizumab has emerged as a promising treatment for Chinese patients with driver-negative advanced or metastatic non-small cell lung cancer (NSCLC). The purpose of our study to evaluate whether tislelizumab is cost-effective as a second- or third-line treatment for this population compared with docetaxel (conventional chemotherapy) and nivolumab (imported PD-1inhibitor), from the perspective of the Chinese healthcare system. Material and Methods: A Markov model with a 3-week Markov cycle and a 30-year time horizon was built to compare the cost-effectiveness of second- or third-line tislelizumab versus docetaxel and nivolumab. Transition probabilities, including disease progression, survival, and adverse events (AEs)-related treatment discontinuation event, were estimated from the clinical trials. Costs and health utilities were collected from local hospitals, public database and published literature. Results: Compared with docetaxel, tislelizumab provided an additional 0.33 quality-adjusted life-years (QALYs) (1.37 vs. 1.04 QALYs) at an incremental cost of $9,286 ($23,646 vs. $14,360) for Chinese patients with driver-negative advanced or metastatic NSCLC, resulting in an incremental cost-effectiveness ratio (ICER) of $27,959/QALY under the WTP threshold of $35,663/QALY used in the model. Compared with nivolumab, tislelizumab was associated with a lower cost ($23,646 vs. $59,447) and higher QALYs (1.37 vs. 1.20 QALYs), resulting in its dominance of nivolumab. Conclusion: From the perspective of the Chinese healthcare system, domestic PD-1inhibitor tislelizumab immunotherapy represents a cost-effective treatment strategy compared with conventional docetaxel chemotherapy and imported PD-1inhibitor nivolumab immunotherapy in the treatment of driver-negative advanced or metastatic NSCLC beyond the first-line setting. In the era of “Universal Medical Insurance System”, the rational use of domestic anticancer drugs guided by cost-benefit evidence would be an effective means to balance the limited expenditure of medical insurance fund and the growing demand for cancer treatments.

Abstract
Objective Results of CameL-sq has revealed the clinical benefits to patients with advanced squamous non-small-cell lung cancer (sq-NSCLC). This study aims to evaluate the cost-effectiveness of camrelizumab plus chemotherapy to treat sq-NSCLC from the perspective of the Chinese healthcare system. Methods We used a partitioned survival model with a lifetime horizon to evaluate the cost-effectiveness of camrelizumab plus chemotherapy vs. chemotherapy in treating sq-NSCLC. Baseline characteristics of patients and key clinical data were extracted from CameL-sq. Costs and utilities were collected from the open-access database and published literature. Costs, quality-adjusted life-years (QALYs), life-years gained, and incremental cost-effectiveness ratios (ICERs) were chosen as economic outcome indicators. We also performed a sensitivity analysis, subgroup analysis, and scenario analysis to verify the stability of the basic analysis results and explore the results under different scenarios. Results Combination therapy added 0.47 QALYS and 0.91 life-years with an incremental cost of $6,347.81 compared with chemotherapy, which had an ICER of $13,572 per QALY. The probabilistic sensitivity analysis indicated that camrelizumab plus chemotherapy had a 37.8% probability of cost-effectiveness at a willingness-to-pay threshold (WTP) of 1 time GDP per capital. When WTP was set as 3 times GDP per capital, combination therapy had significant cost-effectiveness. Deterministic sensitivity analysis showed that cost of the best supportive care was the factor with the greatest influence. The subgroup analysis found that combination therapy was associated with cost-effectiveness in several subgroups, namely, patients with disease stage IIIB/IIIC and with PD-L1 tumor proportion score ≤ 1%. Scenario analysis showed that ICER was positively correlated with the price of camrelizumab. Conclusion In this economic evaluation, camrelizumab plus chemotherapy was unlikely to be cost-effective compared with chemotherapy in the first line therapy of sq-NSCLC from a perspective of the Chinese healthcare system. Reducing the price of camrelizumab and tailoring treatments based on individual patient factors might improve the cost-effectiveness. Our findings may provide evidence for clinicians in making optimal decisions in general clinical practice.

Abstract
OBJECTIVE Camrelizumab is a selective, humanised, high-affinity IgG4 kappa monoclonal antibody against programmed cell death 1 that shows effective antitumour activity with acceptable toxicity in multiple tumour types. The CameL trial demonstrated that camrelizumab plus chemotherapy (CC) significantly prolonged the median progression-free survival and median overall survival versus chemotherapy alone (CA) in patients with advanced non-squamous non-small cell lung cancer (NSCLC). Our study was conducted to investigate the cost-effectiveness of the two strategies in chemotherapy-naive patients with advanced non-squamous NSCLC. DESIGN, SETTING AND PARTICIPANTS A Markov simulation model was generated based on the CameL trial. The two simulated treatments included CC and CA. PRIMARY AND SECONDARY OUTCOME MEASURES Utility was derived from published literature, and costs were calculated based on those at our hospital in Chengdu, China. Incremental cost-effectiveness ratios (ICERs) were calculated to compare the cost-effectiveness of the two treatment arms. RESULTS In the overall population, the total costs were $27 223.40 and $13 740.10 for CC and CA treatment, respectively. The CC treatment produced 1.37 quality-adjusted life years (QALYs), and the CA treatment produced 1.17 QALYs. Hence, patients who were in the CC group spent an additional $13 483.30 and generated an increase of 0.20 QALYs, resulting in an ICER of $67 416.50 per QALY. CONCLUSIONS For chemotherapy-naive patients with advanced non-squamous NSCLC, CC is not considered a cost-effective treatment versus CA in China when considering a willingness-to-pay threshold of $31 500 per QALY.

Abstract
Objective: To investigate the cost-effectiveness of adding Chinese-developed anti-PD-1 antibody tislelizumab to first-line pemetrexed-platinum chemotherapy in (1) a study population of patients with locally advanced or metastatic nonsquamous non-small cell lung cancer (nsqNSCLC) and without known sensitizing EGFR mutations or ALK rearrangements and (2) its subgroups from the perspective of Chinese healthcare system.Material and Methods: Separate Markov models were constructed for the entire study population and its subgroups; 10,000 patients with locally advanced or metastatic nsqNSCLC and without driver gene mutations were simulated in the first-line tislelizumab plus pemetrexed-platinum (TPP) arm and first-line pemetrexed-platinum (PP) arm, respectively. Transition probabilities were extracted from the RATIONALE 304 trial. Public health state utilities and costs were obtained from published literature, public national databases, and local general hospitals. The main outputs were incremental cost-effectiveness ratios (ICERs). The ICERs were compared to a willingness-to-pay threshold of $35,663 per quality-adjusted life-years (QALYs) to determine the cost-effective treatment. Sensitivity analyses were employed to assess the uncertainty in the model.Results: For the entire patient population, first-line TPP versus PP use increased the effectiveness by 0.99 QALYs and healthcare costs by $28,749, resulting in an ICER of $28,749/QALY that was lower than the prespecified WTP threshold. For patient subgroups, first-line TPP conferred the greatest survival benefit in patients with PD-L1 expression ≥50%, followed by patients with liver metastasis and those who are current or former smokers. Overall, the ICERs for the first-line TPP versus PP ranged from $27,018/QALYs to $33,074/QALYs, which were consistently below the WTP threshold.Conclusion: For Chinese patients with locally advanced or metastatic nsqNSCLC who had no known sensitizing EGFR mutations or ALK rearrangements, adding the Chinese-developed anti-PD-1 antibody tislelizumab to the first-line pemetrexed-platinum chemotherapy was cost-effective regardless of their baseline characteristics.

Abstract
Background Lung cancer is imposing significant pressure on the national health insurance system worldwide, especially under the COVID-19 pandemic. However, the cost-effectiveness of all available first-line treatments for patients with advanced epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC) is still uncertain. The aim of this study was to evaluate the cost-effectiveness of 12 first-line treatments for patients with advanced EGFR mutated NSCLC from the perspective of the United Kingdom (UK) National Health Service and Chinese health care system. Methods We used a Markov model to estimate the cost-effectiveness of 12 treatments, including 6 EGFR tyrosine kinase inhibitors, 4 combination treatments and 2 chemotherapies. The key clinical efficacy and safety data were from a network meta-analysis. The cost and health preference were mainly collected from the literature. The most cost-effective treatment was inferred through a sequential analysis. Uncertainty was tested with one-way sensitivity analyses, scenario analyses, and probabilistic sensitivity analyses. Quality-adjusted life years (QALYs), direct medical costs, and incremental cost-effectiveness ratio (ICER) were estimated, at willingness-to-pay thresholds of £20000 to £50000 and £8000 to £24000 per QALY in the UK and China respectively. Results For clinical effectiveness, osimertinib and gefitinib plus pemetrexed based chemotherapy (PbCT) yielded the highest QALYs, while two chemotherapy treatments gained the lowest QALYs. For costs, gefitinib treatment was the cheapest option in both countries (£24529 in the UK and £12961 in China). For cost-effectiveness, 4 treatments including gefitinib, gefitinib plus pemetrexed, gefitinib plus PbCT, and osimertinib formed the cost-effectiveness frontier in both countries. Gefitinib alone (70.7% and 80.0% under the threshold of £20000 and £8000 per QALY in the UK and China, respectively) and gefitinib plus PbCT (62.3% and 71.2% under the threshold of £50000 and £24000 per QALY in the UK and China, respectively) were most likely to be cost-effective compared with other first-line treatments. Conclusions Gefitinib and gefitinib plus PbCT were likely to be cost-effective for patients with advanced EGFR mutated NSCLC in both countries.

Cost-Effectiveness of Bevacizumab Biosimilar LY01008 Combined With Chemotherapy as First-Line Treatment for Chinese Patients With Advanced or Recurrent Nonsquamous Non-Small Cell Lung Cancer. Front Pharmacol 2022; 13:832215. [PMID: 35517823 PMCID: PMC9062292 DOI: 10.3389/fphar.2022.832215] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 03/10/2022] [Indexed: 01/15/2023] Open
Abstract
Objective: To investigate whether LY01008, a locally developed bevacizumab biosimilar agent, is appropriate for widespread use among Chinese advanced or recurrent nonsquamous non-small cell lung cancer (NSCLC) patients, our current study was designed to evaluate the cost-effectiveness of first-line LY01008 combined with platinum-doublet chemotherapy versus chemotherapy alone from the perspective of the Chinese healthcare system. Material and Methods: This economic evaluation designed a Markov model to compare the healthcare cost and quality-adjusted life-year (QALY) of first-line LY01008 combined with chemotherapy versus first-line chemotherapy. Transition probabilities, including disease progression, survival, and adverse event (AE)-related discontinuation of first-line treatment, were estimated using data from the clinical trials. Costs and health utilities were derived from local databases, hospitals, and published literature. Our base case analysis and scenario analysis focused on the cost-effectiveness of chemotherapy combined with a clinical trial dosage (15 mg/kg every 3-week cycle) and a real-world dosage (7.5 mg/kg every 3-week cycle) of LY01008, respectively. Results: In the base case analysis, first-line LY01008 combined with chemotherapy was associated with an increase of 0.48 QALYs in effectiveness and an increase of CNY 189,988 (US$ 26,240) in healthcare costs compared with first-line chemotherapy, resulting an incremental cost-effectiveness ratio (ICER) of CNY 375,425 (US$ 54,430)/QALY. In the scenario analysis, first-line LY01008 combined with chemotherapy was associated with a mean healthcare cost of CNY 265,060 (US$ 38,429), resulting an ICER of CNY 221,579 (US$ 32,125/QALY) between first-line LY01008 combined with chemotherapy versus first-line chemotherapy. The parameters that determine the cost of LY01008 have the greatest impact on the cost-effectiveness results. Conclusion: From the perspective of the Chinese healthcare system, first-line LY01008 at a real-world dosage combined with chemotherapy is likely to represent a cost-effective strategy compared with first-line chemotherapy alone for Chinese advanced or recurrent nonsquamous NSCLC patients.

Abstract
PURPOSE To assess health-related quality of life (HRQoL) and utility scores of lung cancer patients treated with traditional Chinese medicine (TCM) in China. METHODS This cross-sectional study included lung cancer patients treated with TCM in seven tertiary hospitals in Shanghai, China. The HRQoL and utility scores of these patients were measured using the five-level EQ-5D (EQ-5D-5L). The EQ-5D-5L utility scores were derived from the Chinese EQ-5D-5L Value Set. The relationships between HRQoL and the socio-demographic and clinical characteristics of these patients were further explored by Tobit regression. RESULTS This study included a total of 347 patients. Their mean ± SD and median EQ-5D-5L utility scores were 0.851 ± 0.198 and 0.893, respectively. The highest proportion of participants reporting problems was observed in pain/discomfort dimension (57.9%) and anxiety/depression (45.5%). Lung cancer patients treated with TCM had poor HRQoL, influenced by cancer clinical stage. CONCLUSION Lung cancer patients treated with TCM have poor HRQoL, with many patients reporting problems in the pain/discomfort and anxiety/depression dimensions. The information on health utility scores and HRQoL of lung cancer patients treated with TCM could be useful for future supportive care, economic evaluations and decision-making in China.

Front Oncol 2021; 11:745493. [PMID: 34966668 PMCID: PMC8710478 DOI: 10.3389/fonc.2021.745493] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 11/22/2021] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE Our previous economic assessment found that nivolumab was not cost-effective for Chinese patients with advanced non-small cell lung cancer (NSCLC) and without EGFR mutations or ALK translocations, when compared with the standard second-line drug docetaxel. However, a greater survival benefit with nivolumab was observed for patients with 1% or greater tumor programmed death ligand 1 (PD-L1) expression. In view of this, we designed the present analysis to explore whether it is cost-effective to use the PD-L1 test to guide second-line nivolumab treatment in China. MATERIAL AND METHODS A Markov model was established to project the lifetime costs and quality-adjusted life-years (QALYs) of three second-line treatment strategies: nivolumab and docetaxel (strategies without a PD-L1 test) and PD-L1 test-based strategy. Deterministic and probabilistic sensitivity analyses were performed to examine the robustness of our results. Additional price reduction and willingness-to-pay (WTP) threshold scenario analyses were performed to explore the impact of economic and health policies with Chinese characteristics on our results. RESULTS The PD-L1 test-based strategy costs approximately CNY 194,607 (USD 28,210) or more and yielded an additional 0.27 QALYs compared to the docetaxel strategy without a PD-L1 test, equating an incremental cost-effectiveness ratio (ICER) of CNY 731,089 (USD 105,978)/QALY. Deterministic sensitivity analyses showed that the price of nivolumab was the strongest source of variation in the ICERs. Probability sensitivity analysis showed that the probability for the PD-L1 test-based strategy being cost-effective increases with the increase of WTP thresholds. CONCLUSION From the perspective of the Chinese healthcare system, using a PD-L1 test to guide second-line nivolumab treatment was not cost-effective. The National Healthcare Security Administration negotiation on the price reduction of nivolumab was found to be the most effective action to improve its cost-effectiveness in China.

Abstract
Background: As the first domestic PD-1 antibody approved for lung cancer in China, camrelizumab has exhibited proven effectiveness for non-small-cell lung cancer (NSCLC) patients. However, the cost-effectiveness of this new regimen remains to be investigated. Objective: To evaluate the cost-effectiveness of camrelizumab combination therapy vs. chemotherapy for previously untreated patients with advanced, non-squamous NSCLC without Alk or Egfr genomic aberrations from the perspective of China's healthcare system. Methods: Based on the CameL trial, the study developed a three-health state Markov model to evaluate the cost-effectiveness of adding camrelizumab to chemotherapy compared to chemotherapy alone in NSCLC patients. The analysis models were conducted for patients unselected by PD-L1 tumor expression (the base case) and the patient subgroup with PD-L1-expressing tumors (≥1%). Primary model outcomes included the costs in US dollars and health outcomes in quality-adjusted life-years (QALYs) as well as the incremental cost-effectiveness ratio (ICER) under a willingness-to-pay threshold of $31,500 per QALY. Additionally, a scenario analysis that adjusted within-trial crossover was employed to evaluate camrelizumab combination therapy compared to chemotherapy without subsequent use of PD1/PD-L1 antibodies. Results: Camrelizumab combination therapy was more costly and provided additional 0.11 QALYs over chemotherapy in the base case analysis (0.86 vs. 0.75 QALYs), 0.12 QALYs over chemotherapy in the subgroup analysis (0.99 vs. 0.88 QALYs), and 0.34 QALYs over chemotherapy in the scenario analysis (0.86 vs. 0.52 QALYs). Correspondingly, the ICER was $63,080 per QALY, $46,311 per QALY, and $30,591 per QALY, in the base case, the subgroup, and the scenario analysis, respectively. One-way sensitivity analyses revealed that ICERs of the base case and the subgroup analysis were most sensitive to the cost of camrelizumab, the cost of pemetrexed. Besides, the base case and subgroup analysis were more sensitive to the risk of neutrophil count decreased in the camrelizumab and the utility of stable disease, respectively. Conclusion: Although camrelizumab combination therapy is not cost-effective as first-line therapy for NSCLC patients in China in the base case, adjusting within-trial crossover would move the treatment regimen toward cost-effectiveness in the scenario analysis.

Cost-Effectiveness of Domestic PD-1 Inhibitor Camrelizumab Combined With Chemotherapy in the First-Line Treatment of Advanced Nonsquamous Non-Small-Cell Lung Cancer in China. Front Pharmacol 2021; 12:728440. [PMID: 34795580 PMCID: PMC8593416 DOI: 10.3389/fphar.2021.728440] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Accepted: 09/20/2021] [Indexed: 01/25/2023] Open
Abstract
Objective: Camrelizumab is the first domestic PD-1inhibitor approved to be combined with chemotherapy as a first-line therapy for advanced nonsquamous non-small-cell lung cancer (NSCLC) in China. The purpose of this study was to determine whether using camrelizumab in the first-line setting is cost-effective in China when compared with traditional chemotherapy or the imported PD-1inhibitor pembrolizumab. Material and Methods: A Markov model was built to simulate 3-week patient transitions over a 30-year horizon from the perspective of the Chinese healthcare system. Health states included stable disease, first progression, second progression, and death. A direct comparison between first-line camrelizumab in combination with pemetrexed and carboplatin (CPC) and pemetrexed plus carboplatin (PC) was performed by calculating transition probabilities from the CameL trial. An indirect comparison between first-line CPC and pembrolizumab in combination with pemetrexed and platinum (PPP) was performed by calculating transition probabilities using a network meta-analysis. Costs in the Chinese setting were collected from the local public database and literatures. Sensitivity analyses explored the uncertainty around model parameters. Results: In the primary analysis, first-line CPC gained an additional 0.41 quality-adjusted life-years (QALYs) with an incremental cost of $3,486 compared with PC, resulting in an incremental cost-effectiveness ratio (ICER) of $8,378 per QALY gained. In the secondary analysis, first-line PPP yielded an additional 0.10 QALYs at an incremental cost of $6,710, resulting in an ICER of $65,563 per QALY gained. Conclusion: For Chinese patients with advanced nonsquamous NSCLC without targetable genetic aberrations, our primary analysis results supported first-line CPC as a cost-effective treatment compared with traditional PC chemotherapy. The findings of our secondary analysis suggested that first-line PPP would not be a cost-effective option compared with first-line CPC. This analysis provided strong evidence for promoting the widespread use of first-line CPC in China and, to some extent, stimulated the enthusiasm for the development of domestic cancer drugs.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of durvalumab in post-chemoradiotherapy patients with unresectable stage III NSCLC from the Chinese healthcare system perspective. METHODS The study developed a five-health state Markov model to evaluate the cost-effectiveness of durvalumab consolidation therapy in post-chemoradiotherapy patients based on the PACIFIC clinical trial. Sensitivity and scenario analyses were performed to evaluate the model uncertainty. RESULTS Durvalumab consolidation therapy provided an additional 1.22 quality-adjusted life-years (QALYs), with an incremental cost of $24,397 compared to no consolidation therapy in unselected patients. Durvalumab consolidation therapy was cost-effective as it yielded an incremental cost-effectiveness ratio (ICER) of $20,000 per QALY gained at a willingness-to-pay (WTP) threshold of $31,494 per QALY. In the patient subgroup with PD-L1-expressing tumors (≥1%), durvalumab was associated with an ICER of $33,058/QALY, resulting in a slight skewing away from the given cost-effectiveness threshold. The sensitivity analysis showed that ICERs were most sensitive to the cost of durvalumab, the cost of pembrolizumab, and the body weight of patients, regardless of PD-L1 expression selection. CONCLUSION Durvalumab consolidation therapy is likely to be cost-effective in China, which indicates that expensive immunotherapies can gain clinical benefits at a justifiable cost in developing countries as well.

Abstract
OBJECTIVES Cancer diagnoses at later stages are associated with a decrease in health-related quality of life (HRQOL). Health state utility values (HSUVs) reflect preference-based HRQOL and can vary based on cancer type, stage, treatment, and disease progression. Detecting and treating cancer at earlier stages may lead to improved HRQOL, which is important for value assessments. We describe published HSUVs by cancer type and stage. METHODS A systematic review was conducted using Embase, MEDLINE®, EconLit, and gray literature to identify studies published from January 1999 to September 2019 that reported HSUVs by cancer type and stage. Disutility values were calculated from differences in reported HSUVs across cancer stages. RESULTS From 13,872 publications, 27 were eligible for evidence synthesis. The most frequent cancer types were breast (n = 9), lung (n = 5), colorectal (n = 4), and cervical cancer (n = 3). Mean HSUVs decreased with increased cancer stage, with consistently lower values seen in stage IV or later-stage cancer across studies (e.g., - 0.74, - 0.44, and - 0.51 for breast, colorectal, and cervical cancer, respectively). Disutility values were highest between later-stage (metastatic or stage IV) cancers compared to earlier-stage (localized or stage I-III) cancers. CONCLUSIONS This study provides a summary of HSUVs across different cancer types and stages that can inform economic evaluations. Despite the large variation in HSUVs overall, a consistent decline in HSUVs can be seen in the later stages, including stage IV. These findings indicate substantial impairment on individuals' quality of life and suggest value in early detection and intervention.

Abstract
BACKGROUND IMpower 133 trial first confirmed the efficacy and safety of adding atezolizumab or placebo to first-line treatment with chemotherapy in patients with extensive-stage small-cell lung cancer (SCLC). While, overprice limited its broad use in clinical. The aim of this study was to evaluate the cost-effectiveness of atezolizumab plus chemotherapy in treatment of extensive SCLC as first line in China. METHODS A Markov model was established by extracting data from the IMpower 133 trial with untreated extensive SCLC patients. Utility values were obtained from published studies, and the costs were acquired from real world and literature. Additionally, sensitivity analyses based on a willingness-to-pay (WTP) threshold were performed to identify the uncertain parameters of Markov model. RESULTS Total costs of atezolizumab group were $48,129, while cost of chemotherapy alone was just $12,920 in placebo group. The quality-adjusted life-years (QALYs) in atezolizumab group was just 0.072 higher than that in placebo group (0.858 QALYs vs. 0.786 QALYs). The cost-effectiveness ratio between atezolizumab combination with chemotherapy and chemotherapy alone was $489,013/QALY in China. The net benefit of placebo group was significantly higher than atezolizumab group. One-way sensitivity analyses highlighted that utilities of the progression-free survival (PFS) and progression disease state in placebo group were the most influential parameter. CONCLUSIONS Atezolizumab combination therapy was not more cost-effective than chemotherapy alone at a WTP threshold of $25,929/QALY in China.

Abstract
OBJECTIVES The ways patients cope with advanced cancer can influence their health-related quality of life (HRQoL). This study aims to examine the mediating role of positive and negative mood in the relationship between coping and HRQoL in patients with advanced lung cancer. METHODS A consecutive sample of 261 patients (mean age: 59.99±9.53) diagnosed with stage III or IV lung cancer was recruited from the inpatient unit in a hospital that specialises in chest-related disease in Shanghai, China. Participants completed measurements including Medical Coping Modes Questionnaire, Positive and Negative Affect Schedule, and 5-level EuroQol 5-dimension instrument. RESULTS Although the total effects of confrontation on HRQoL were not significant, competing indirect effects via mood were identified: (1) positive indirect effects through positive mood were found for confrontation on mobility, usual activities, pain/discomfort and overall utility index (indirect effect=0.01, 95% CI 0.003 to 0.03); (2) negative indirect effects through negative mood were found for confrontation on mobility, pain/discomfort, anxiety/depression and overall utility index (indirect effect=-0.01, 95% CI -0.03 to -0.001). Resigned acceptance was negatively associated with HRQoL, and indirect effects via mood were identified: (1) negative indirect effects through positive mood were found for resigned acceptance on mobility, self-care, usual activities, pain/discomfort and overall utility index (indirect effect=-0.01, 95% CI -0.03 to -0.003); (2) negative indirect effects through negative mood were found for resigned acceptance on domains of HRQoL and overall utility index (indirect effect=-0.04, 95% CI -0.06 to -0.02). CONCLUSIONS Confronting advanced lung cancer can fuel ambivalent emotional experiences. Nevertheless, accepting the illness in a resigned way can be maladaptive for health outcomes. The findings suggest interventions that facilitate adaptive coping, reduce negative mood and enhance positive mood, as this could help to improve or maintain HRQoL in patients with advanced lung cancer.

Abstract
INTRODUCTION To assess the cost-effectiveness of alectinib versus crizotinib as first-line treatments for advanced anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) patients from the perspective of China's healthcare system. METHODS A Markov model was developed to assess the clinical outcomes and costs of alectinib and crizotinib, which included five health states: progression-free (PF) without central nervous system (CNS) progression, PF with CNS progression, post-progression (PP) without CNS progression, PP with CNS progression, and death. Clinical data for transition probabilities were obtained from the ALEX trial at the updated data cutoff. Healthcare resource utilization and costs were derived from clinical expert opinions and published literature. One-way sensitivity analysis and probabilistic sensitivity analysis were conducted to assess the uncertainty of the results. Scenario analyses were conducted including using clinical data from the ALESIA trial in Asian patients, using utilities from the ALEX trial, and choosing different parametric survival models. RESULTS In base case analysis, alectinib yielded an additional 1.04 quality-adjusted life years (QALYs) with incremental costs of $54,827, resulting in an incremental cost-effectiveness ratio (ICER) of $52,869/QALY. In scenario analysis, the ICER was $56,787/QALY using clinical data from the ALESIA trial. In probabilistic sensitivity analysis, the probabilities of alectinib being cost-effective were 0.4% and 43.7% when the willingness-to-pay (WTP) thresholds were $28,109/QALY and $50,000/QALY, respectively. CONCLUSION Alectinib could prolong the mean time of PF and delay the time to CNS progression. However, because of its high drug cost, alectinib was unlikely to be cost-effective for untreated ALK-positive NSCLC patients in China.
