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.

Cost-effectiveness of tumor-treating fields plus standard therapy for advanced non-small cell lung cancer progressed after platinum-based therapy in the United States. Front Pharmacol 2024; 15:1333128. [PMID: 38375030 PMCID: PMC10875105 DOI: 10.3389/fphar.2024.1333128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Accepted: 01/26/2024] [Indexed: 02/21/2024] Open
Abstract
Background: Tumor treating fields (TTF) was first approved for treatment of glioblastoma. Recently, the LUNAR study demonstrated that TTF + standard therapy (ST) extended survival in patients with advanced non-small cell lung cancer (NSCLC). This primary objective of this study is to analyze the cost-effectiveness of this treatment from the United States healthcare payers' perspective. Methods: A 3-health-state Markov model was established to compare the cost-effectiveness of TTF + ST and that of ST alone. Clinical data were extracted from the LUNAR study, supplemented by additional cost and utility data obtained from publications or online sources. One-way sensitivity analysis, probabilistic sensitivity analysis, and scenario analysis were conducted. The willingness-to-pay (WTP) threshold per quality-adjusted life-years (QALYs) gained was set to $150,000. The main results include total costs, QALYs, incremental cost-effectiveness ratio (ICER) and incremental net monetary benefit (INMB). Subgroup analyses were conducted for two types of ST, including immune checkpoint inhibitor, and docetaxel. Results: During a 10-year time horizon, the costs of TTF + ST and ST alone were $431,207.0 and $128,125.9, and the QALYs were 1.809 and 1.124, respectively. The ICER of TTF + ST compared to ST was $442,732.7 per QALY, and the INMB was -$200,395.7 at the WTP threshold. The cost of TTF per month was the most influential factor in cost-effectiveness, and TTF + ST had a 0% probability of being cost-effective at the WTP threshold compared with ST alone. Conclusion: TTF + ST is not a cost-effective treatment for advanced NSCLC patients who progressed after platinum-based therapy from the perspective of the United States healthcare payers.

Abstract
OBJECTIVES The current study aimed to evaluate the cost-effectiveness of sintilimab versus docetaxel as second-line treatment for patients with advanced or metastatic squamous non-small-cell lung cancer (NSCLC) in China. METHODS A partitioned survival model was established to track 3-week patients' transition and project the health and economic outputs in 15-year horizon of the two competing options among sintilimab and docetaxel. Clinical data were obtained from the ORIENT-3 trial, and cost and utility values were gathered from the local charges and published studies. Total costs, life-years, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) were evaluated. Sensitivity analyses were conducted to assess the robustness of the model outcomes. RESULTS Base-case results revealed that sintilimab yield marginal cost of $4,700.53 and additional 0.32 QALYs, resulting in an ICER of $14,615.31 per QALY gained, which is lower than the willingness-to-pay threshold of $38,224/QALY in China. One-way sensitivity analyses showed that the cost of best supportive care was the main driver of the ICER, and probabilistic sensitivity analyses demonstrated that the model outputs were robust. CONCLUSIONS Sintilimab could be considered the cost-effective second-line strategy for patients with advanced or metastatic squamous NSCLC compared with docetaxel in China.

Front Immunol 2023; 14:1169752. [PMID: 37313403 PMCID: PMC10258326 DOI: 10.3389/fimmu.2023.1169752] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 05/19/2023] [Indexed: 06/15/2023] Open
Abstract
Background Toripalimab is the first domestic anti-tumor programmed death 1 antibody marketed in China. The CHOICE-01 trial (identifier: NCT03856411) demonstrated that toripalimab plus chemotherapy can significantly improve the clinical outcomes of advanced non-small cell lung cancer (NSCLC) patients. However, whether it is cost-effective remains unknown. Given the high cost of combination therapy, a cost-effectiveness analysis of toripalimab plus chemotherapy (TC) versus chemotherapy alone (PC) for the first-line treatment of patients with advanced NSCLC is required. Methods A partitioned survival model was adopted to predict the course of disease in advanced NSCLC patients on TC or PC from the perspective of the Chinese healthcare system over a 10-year horizon. The survival data were obtained from the CHOICE-01 clinical trial. Cost and utility values were obtained from local hospitals and kinds of literature. Based on these parameters, the incremental cost-effectiveness ratio (ICER) of TC vs. PC was measured, and one-way sensitivity analyses, probabilistic sensitivity analyses (PSA), and scenario analyses were performed to assess the robustness of the model. Results In the base case, TC was associated with an incremental cost of $18510 and an incremental quality-adjusted life year (QALY) of 0.57 compared with PC, resulting in an ICER of $32237/QALY which was lower than the willingness to pay (WTP) threshold ($37654/QALY), TC was cost-effective. The health utility value of progression-free survival, the price of toripalimab, and the cost of best supportive care were factors that significantly influenced the ICER, but no change in any of them could change the model result. TC showed a 90% probability of being a cost-effective option at a WTP threshold of $37,654/QALY. In the 20 and 30-year time horizons, the results remained unchanged and TC remained cost-effective when the second-line treatment was switched to docetaxel. Conclusion At a WTP threshold of $37,654 per QALY, TC was cost-effective compared to PC for patients with advanced NSCLC in China.

Dai H, Wang W, Fan X, Chen Y. Cost-effectiveness of camrelizumab plus chemotherapy vs. chemotherapy in the first-line treatment of non-squamous NSCLC: Evidence from China. Front Med (Lausanne) 2023; 10:1122731. [PMID: 36865055 PMCID: PMC9971596 DOI: 10.3389/fmed.2023.1122731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 01/30/2023] [Indexed: 02/16/2023] Open
Abstract
Objective We aimed to evaluate the cost-effectiveness of camrelizumab plus chemotherapy compared with chemotherapy alone as the first-line treatment for patients with metastatic or advanced non-squamous non-small cell lung cancer (NSCLC) without targetable epidermal growth factor receptor or anaplastic lymphoma kinase genetic aberrations in patients in China. Methods A partitioned survival model was constructed to estimate the cost-effectiveness of camrelizumab plus chemotherapy vs. chemotherapy in the first-line treatment of non-squamous NSCLC from a Chinese healthcare perspective. Survival analysis was performed to calculate the proportion of patients in each state using data from trial NCT03134872. The cost of drugs was obtained from Menet, and the cost of disease management was obtained from local hospitals. Health state data were obtained from published literature. Both deterministic sensitivity analyses (DSA) and probabilistic sensitivity analysis (PSA) were adopted to verify the robustness of the results. Results Compared with chemotherapy alone, camrelizumab plus chemotherapy provided 0.41 incremental quality-adjusted life years (QALYs) at an incremental cost of $10,482.12. Therefore, the incremental cost-effectiveness ratio of camrelizumab plus chemotherapy was $25,375.96/QALY from the Chinese healthcare perspective, much lower than three times the GDP per capita of China in 2021 ($35,936.09) as the willingness-to-pay threshold. The DSA indicated that the incremental cost-effectiveness ratio was most sensitive to the utility value of progression-free survival, followed by the cost of camrelizumab. The PSA illustrated that camrelizumab had 80% probability of being cost-effective at the threshold of $35,936.09 per QALY gained. Conclusion The results suggest that camrelizumab plus chemotherapy is a cost-effective choice in the first-line treatment for patients with non-squamous NSCLC in China. Although this study has limitations such as short time of use of camrelizumab, no adjustment of Kaplan-Meier curves and the median overall survival that has not been reached, the difference in results caused by these factors is relatively small.
