Lang W, Deng L, Lu M, Ouyang M. Cost-effectiveness analysis of pembrolizumab plus chemotherapy versus placebo plus chemotherapy for HER2-negative advanced gastric/gastroesophageal junction cancer in the Chinese healthcare system. Expert Rev Pharmacoecon Outcomes Res 2024; 24:1027-1042. [PMID: 38979910 DOI: 10.1080/14737167.2024.2378983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 06/17/2024] [Indexed: 07/10/2024]
Abstract
BACKGROUND This study compares first-line pembrolizumab plus chemotherapy with chemotherapy alone for patients with HER2-negative advanced gastric cancer (GC) and gastroesophageal junction cancer (GEJC) in China. METHODS A Markov state-transition model was developed based on the phase 3 randomized KEYNOTE-859 clinical trial data. The health state utility values and direct medical costs were derived from the KEYNOTE-859 clinical trial, the relevant literature, and local charges. The measured outcomes included quality-adjusted life-years (QALYs) and the incremental cost-effectiveness ratio (ICER). Probabilistic and one-way sensitivity analyses (OWSA) were performed to assess the uncertainty of the model. RESULTS In the base analysis, the incremental effectiveness and cost of pembrolizumab plus chemotherapy versus chemotherapy alone were 0.22 QALYs and $16,627.31, respectively, resulting in an ICER of $76,936.60/QALY, which is higher than the willingness-to-pay threshold in China ($35,864.61/QALY). Subgroup analyses revealed that the ICERs of pembrolizumab plus chemotherapy versus chemotherapy alone were $72,762.68 and $34,813.70 in the populations with PD-L1 CPS of 1 or higher (CPS ≥ 1) and PD-L1 CPS ≥ 10 (CPS ≥ 10), respectively. CONCLUSIONS As first-line therapy for patients with locally advanced or metastatic HER2-negative GC/GEJC in China, pembrolizumab plus chemotherapy is less cost-effective than chemotherapy alone, however, in the CPS ≥ 10 subgroup is more.

Abstract
BACKGROUND To evaluate the cost-effectiveness of first-line sintilimab plus chemotherapy versus chemotherapy for advanced esophageal squamous cell carcinoma (ESCC) from the perspective of the Chinese health service system. METHODS A partitioned survival model was constructed to simulate quality-adjusted life years and incremental cost-effectiveness ratios over a patient's lifetime based on a phase III clinical trial. RESULTS Sintilimab plus chemotherapy increased by 0.316 QALY and 0.285 QALY with the additional cost of $5692 and $5269, which led to the ICER of $18000/QALY and $18519/QALY gained in the overall population and the patients with CPS ≥ 10, respectively. CONCLUSIONS Compared with chemotherapy alone, sintilimab may be a cost-effective first-line treatment choice for locally advanced or metastatic ESCC.

Abstract
OBJECTIVES ORIENT-16, a phase III clinical trial conducted at 62 hospitals in China, reported that add-on sintilimab (Sin) to chemotherapy (Chemo) had favorable efficacy (p < 0.05) for patients with advanced HER2-negative gastric or gastroesophageal junction cancer (GC/GEJC). This study aimed to evaluate the cost-utility of the Sin+Chemo based on results of ORIENT-16 from the perspective of Chinese healthcare payers. METHODS A three-state partitioned survival model was developed to simulate the 10-year life expectancy and total healthcare costs for patients with advanced HER2-negative GC/GEJC. Primary measure outcomes were: cost, quality-adjusted life-years (QALYs), and incremental cost-utility ratios (ICURs). Sensitivity/scenario analyses were conducted to assess the model robustness. RESULTS In all patients, Sin+Chemo vs Chemo increased costs by $6,472, additionally providing 0.61 QALYs, resulting in an ICUR of $10,610/QALY. While, in PD-L1 combined positive score ≥ 5 cohort, the ICUR was $9,738/QALYs. The ICUR was most sensitive to the utility of progression-free survival. The probabilistic sensitivity analysis showed that add-on Sin had a 100% probability of being cost-effective at a willingness-to-pay threshold of $18,625/QALY gained. CONCLUSIONS Sin+Chemo is a cost-effective first-line treatment option for advanced HER2-negative GC/GEJC in China. CLINICAL TRIAL REGISTRATION ORIENT-16, www.clinicaltrials.gov, identifier is NCT03745170.

Immune checkpoint inhibitors as the second-line treatment for advanced esophageal squamous cell carcinoma: a cost-effectiveness analysis based on network meta-analysis. BMC Cancer 2024; 24:654. [PMID: 38811891 PMCID: PMC11134960 DOI: 10.1186/s12885-024-12423-2] [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: 01/06/2024] [Accepted: 05/23/2024] [Indexed: 05/31/2024] Open
Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) have demonstrated superior clinical efficacy in prolonging overall survival (OS) as the second-line treatment for advanced or metastatic esophageal squamous cell carcinoma (ESCC), and were recommended by the guidelines. However, it remains uncertain which ICI is the most cost-effective. This study assessed the cost-effectiveness of ICIs as the second-line treatment for ESCC based on the perspective of the Chinese healthcare system. METHODS A network meta-analysis (NMA) was performed to obtain the Hazard ratios (HRs) for indirect comparisons. A three-state Markov model with a 10-year time horizon was conducted to assess the cost-effectiveness. The state transition probabilities were calculated with Kaplan-Meier (KM) curves data from clinical trial and HRs from the NMA. Utilities and costs were derived from local charges or previously published studies. Univariate and probabilistic sensitivity analyses (PSA) were performed to examine model robustness. The results were assessed based on the total costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs). RESULTS Five clinical trials (ATTRACTION-3, ESCORT, KEYNOTE-181, ORIENT-2, RATIONALE-302) with a total of 1797 patients were included in the NMA. The NMA showed that both camrelizumab and tislelizumab received relatively high rankings for progression-free survival (PFS) and OS. Compared with sintilimab, treatment with tislelizumab and camrelizumab gained 0.018 and 0.034 additional QALYs, resulting in incremental ICERs of $75,472.65/QALY and $175,681.9/QALY, respectively. Nivolumab and pembrolizumab produced lower QALYs and greater costs, suggesting that both were dominated in comparison to sintilimab. HRs and health state utilities were the most influential parameters in most univariate sensitivity analyses of paired comparisons. PSA results suggested that sintilimab had an 84.4% chance of being the most cost-effective treatment regimen at the WTP threshold of $38,223.34/QALY. In the scenario analysis, sintilimab would no longer be cost-effective, if the price of camrelizumab was assumed to decrease by 64.6% or the price of tislelizumab was assumed to decrease by 16.9%. CONCLUSIONS AND RELEVANCE Among the five potential competing ICIs, sintilimab was likely to be the most cost-effective regimen as the second-line treatment for locally advanced or metastatic ESCC in China.

Abstract
Introduction First-line treatment with tislelizumab plus chemotherapy has shown clinical benefits for patients with advanced or metastatic esophageal squamous cell carcinoma (OSCC) in China, while its economic burden is unknown. This study aimed to evaluate the cost-effectiveness of tislelizumab plus chemotherapy from the perspective of the Chinese healthcare system. Methods We constructed a partitioned survival model to compare the cost-effectiveness of tislelizumab plus chemotherapy with chemotherapy in patients with advanced OSCC. Patient characteristics and clinical outcomes were extracted from RATIONALE-306. Costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were selected as the study outcomes. Sensitivity analysis and subgroup analysis were conducted to test the stability of the results. Results Tislelizumab plus chemotherapy provided additional 0.48 QALYs with the incremental cost of $16,587.2 than chemotherapy, of which ICER was $34,699.72 per QALY. When the willingness-to-pay threshold was set as $37,260, the novel therapy had a probability of 77% to be cost-effective. Our base-case analysis results were sensitive to utilities of progression-free survival and progression of disease. Our subgroup analysis showed that the novel therapy was associated with cost-effectiveness in patients with a high expression of PD-L1. Conclusion Tislelizumab plus chemotherapy was likely to be more cost-effective compared with chemotherapy in the first-line therapy of advanced OSCC from the perspective of the Chinese healthcare system. Our findings can provide clinicians and decision-makers with evidence of the cost-effectiveness of tislelizumab.

Abstract
Objective Amivantamab plus chemotherapy has been proved to be an efficient treatment strategy for non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertions. The aim of this study was to conduct the cost-effectiveness analysis of amivantamab-chemotherapy compared with chemotherapy alone in NSCLC harboring EGFR exon 20 insertion mutations. Methods We constructed a Markov model based on the data derived from the PAPILLON trial. We evaluated the cost, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were used to evaluate the influence of different parameters on this model. Results Compared with chemotherapy alone, amivantamab combined with chemotherapy treatment gained an incremental effectiveness of 0.473 QALYs and an incremental cost of $361,950.952, which resulted in an ICER of $765,224/QALY. The ICER was much higher than the willingness-to-pay threshold of 15,0000/QALY. One-way sensitivity analysis revealed that amivantamab cost was the leading influential factor in the model. Conclusions Compared with chemotherapy alone, amivantamab plus chemotherapy is not a cost-effective first-line treatment choice for NSCLC patients with EGFR exon 20 insertions. The costly price of amivantamab is one of the major reasons for the high cost of this combined treatment strategy. Therefore, it is imperative to take into account the high cost of amivantamab in the subsequent clinical application and strive to attain a relative equilibrium between its significant clinical benefit and economic encumbrance.

Abstract
Background Recently, several novel programmed cell death protein 1 (PD-1) inhibitors have been approved for second-line treating advanced or metastatic oesophageal squamous cell carcinoma (OSCC), including camrelizumab, nivolumab, pembrolizumab, sintilimab and tislelizumab. However, the optimal treatment regimen remained ambiguous. Objectives The purpose of this study was to investigate the efficacy, safety and economy of available PD-1 inhibitors to determine the optimal treatment from the Chinese healthcare system perspective. Design A systematic review and economic evaluation. Data sources and methods A systematic review was undertaken utilizing PubMed, Web of Science, Cochrane Library, Embase and Scopus databases to identify eligible studies until 31 August 2023. Primary outcomes were progression-free survival (PFS), overall survival (OS) and adverse events (AEs). We also developed a partitioned survival model at 3-week intervals based on five clinical trials to predict long-term costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios for various treatment options. Direct medical costs and utility values were obtained from public drug bidding databases, clinical trials or published literature. The parameter uncertainties within the model were determined via one-way and probabilistic sensitivity analyses. Results Five randomized controlled trials involving 2837 patients were included in the analysis. Compared with other treatments examined, camrelizumab provided the best PFS benefits [hazard ratio (HR): 0.69, 95% confidence interval (CI): 0.56-0.86], and pembrolizumab provided the best OS benefits (HR: 0.55, 95% CI: 0.37-0.82). Nivolumab caused a relatively lower incidence of treatment-related AEs (HR: 0.10, 95% CI: 0.05-0.20) and grade 3-5 AEs (HR: 0.13, 95% CI: 0.08-0.21) than other immunotherapy regimens. In the economic evaluation, average 10-year costs ranged from $5,433.86 (chemotherapy) to $50,617.95 (nivolumab) and mean QALYs ranged from 0.55 (chemotherapy) to 0.82 (camrelizumab). Pembrolizumab was eliminated because of dominance. Of the remaining strategies, when the willingness-to-pay thresholds were 1, 2 and 3 times GDP per capita in 2022, sintilimab, tislelizumab and camrelizumab were the most cost-effective treatment options, respectively. Conclusion Sintilimab might be the optimal treatment alternative for second-line therapy of advanced OSCC in China, followed by tislelizumab and camrelizumab. Trial registration This study has been registered on the PROSPERO database with the registration number CRD42023495204.

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.

Abstract
OBJECTIVE The ASTRUM-007 study confirmed the significant efficacy and safety of serplulimab plus chemotherapy for patients with locally advanced/metastatic, programmed cell death-ligand 1 positive oesophageal squamous cell carcinoma (OSCC). The economics of this regimen, however, is unclear. Therefore, this study aimed to evaluate the cost-effectiveness of adding serplulimab to chemotherapy for the treatment of advanced OSCC from the perspective of the Chinese healthcare system. DESIGN A partitioned survival model was established to simulate the costs and outcomes of chemotherapy versus serplulimab plus chemotherapy. The survival data came from the ASTRUM-007 study. Only direct medical costs were considered, and utility values were referred to the literature. Sensitivity analysis was performed to assess the effect of parameter uncertainty on the model. OUTCOME MEASURES Total costs, incremental costs, life years, quality-adjusted life years (QALYs), incremental QALYs and incremental cost-effectiveness ratio (ICER). RESULTS The base case analysis showed that the cost of serplulimab plus chemotherapy (US$69 356) was US$41 607 higher than that of chemotherapy (US$27 749), but it also gained 0.38 QALYs more (1.38 vs 1 QALYs), with an ICER of US$110 744.36/QALY, which was higher than the willingness to pay. The factors that most influenced the ICER were the price of serplulimab, weight and utility value of the progression-free survival stage. The subgroup analysis and scenario analysis also demonstrated that serplulimab plus chemotherapy was not economical. CONCLUSIONS Compared with chemotherapy, serplulimab coupled with chemotherapy was not cost-effective for the treatment of advanced OSCC in China.

Liu S, Jiang N, Dou L, Li S. Cost-effectiveness analysis of serplulimab plus chemotherapy in the first-line treatment for PD-L1-positive esophageal squamous cell carcinoma in China. Front Immunol 2023; 14:1172242. [PMID: 37215110 PMCID: PMC10192749 DOI: 10.3389/fimmu.2023.1172242] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 04/17/2023] [Indexed: 05/24/2023] Open
Abstract
Objective The ASTRUM-007 trial (NCT03958890) demonstrated that serplulimab plus chemotherapy administered every 2-week significantly improved progression-free and overall survival in patients with previously untreated, programmed death-ligand 1 (PD-L1) positive advanced esophageal squamous-cell carcinoma (ESCC). This study was aimed to investigate the cost-effectiveness of serplulimab plus chemotherapy in the first-line treatment of PD-L1-positive advanced ESCC. Methods A partitioned survival model with a 2-week cycle and a 10-year time horizon was constructed from the Chinese healthcare system perspective. The survival data, direct medical costs and utilities were derived from the ASTRUM-007 trial, YAOZHI database and published sources. Total costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs) were calculated. Scenario, one-way and probabilistic sensitivity analyses were performed to assess the uncertainty around model parameters. Results Compared with chemotherapy, serplulimab plus chemotherapy provided additional 0.27 QALYs with an incremental cost of $33,460.86, which had an ICER of $124,483.07 per QALY. The subgroup analyses revealed that the ICERs of serplulimab plus chemotherapy were $134,637.42 and $105,589.71 in advanced ESCC patients with 1 ≤ CPS < 10 and CPS ≥ 10, respectively. The price of serplulimab, patient weight, utility values and discount rate were the most influential parameters on base-case results. At a willingness-to-pay threshold of three times per capita GDP ($40,587.59) in 2022, the probability of serplulimab plus chemotherapy being cost-effective was 0% compared with chemotherapy. When the price of serplulimab decreased by 70%, the probabilities of serplulimab plus chemotherapy being cost-effective were 81.42%, 67.74% and 96.75% in advanced ESCC patients with PD-L1-positive, PD-L1 1≤CPS<10 and CPS≥10, respectively. Conclusion Serplulimab plus chemotherapy in the first-line treatment for PD-L1-positive advanced ESCC might not be cost-effective in China.

Liu S, Dou L, Li S. Cost-effectiveness analysis of PD-1 inhibitors combined with chemotherapy as first-line therapy for advanced esophageal squamous-cell carcinoma in China. Front Pharmacol 2023; 14:1055727. [PMID: 36937861 PMCID: PMC10017726 DOI: 10.3389/fphar.2023.1055727] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 02/20/2023] [Indexed: 03/06/2023] Open
Abstract
Objective: This study was aimed to investigate the cost-effectiveness of all available programmed death 1 (PD-1) inhibitors combined with chemotherapy in the first-line treatment of advanced esophageal squamous-cell carcinoma (ESCC) from the Chinese healthcare system perspective. Methods: A partitioned survival model with a 3-week cycle and a 10-year time horizon was constructed based on a network meta-analysis. The survival data and utility values were derived from clinical trials, and the direct medical costs were collected from public drug bidding database and published literature. Total costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs) were calculated. Scenario, one-way and probabilistic sensitivity analyses were performed to assess the uncertainty around model parameters. Results: Compared with mono-chemotherapy, toripalimab, sintilimab and camrelizumab plus chemotherapy were cost-effective treatment regimens, while serplulimab, pembrolizumab and nivolumab plus chemotherapy were not cost-effective options. Toripalimab plus chemotherapy provided the highest QALYs of 0.95 with the lower cost of $8,110.53 compared to other competing alternatives. The robustness of the base-case results was confirmed by scenario and one-way sensitivity analysis. At a willingness-to-pay threshold of three times per capita gross domestic product ($38,351.20) in 2021, the probability of toripalimab plus chemotherapy being the optimal option was 74.25% compared with other six competing alternatives. Conclusion: Toripalimab plus chemotherapy represented the most cost-effective option as the first-line therapy for advanced ESCC patients in China.
