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 2024:1-16. [PMID: 38979910 DOI: 10.1080/14737167.2024.2378983] [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: 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.

Gong H, Ong SC, Li F, Shen Y, Weng Z, Zhao K, Jiang Z, Wang M. Cost-effectiveness of immune checkpoint inhibitors as a first-line therapy for advanced hepatocellular carcinoma: a systematic review. HEALTH ECONOMICS REVIEW 2024; 14:48. [PMID: 38967718 PMCID: PMC11225220 DOI: 10.1186/s13561-024-00526-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 06/25/2024] [Indexed: 07/06/2024]
Abstract
Since 2017, immune checkpoint inhibitors (ICIs) have been available for the treatment of advanced hepatocellular carcinoma (HCC) or unresectable HCC, but their adoption into national medical insurance programs is still limited. Cost-effectiveness evidence can help to inform treatment decisions. This systematic review aimed to provide a critical summary of economic evaluations of ICIs as a treatment for advanced HCC and identify key drivers (PROSPERO 2023: CRD42023417391). The databases used included Scopus, Web of Science, PubMed, Embase, and Cochrane Central. Economic evaluations of ICIs for the treatment of advanced HCC were included. Studies were screened by two people. Of the 898 records identified, 17 articles were included. The current evidence showed that ICIs, including atezolizumab plus bevacizumab, sintilimab plus bevacizumab/bevacizumab biosimilar, nivolumab, camrelizumab plus rivoceranib, pembrolizumab plus lenvatinib, tislelizumab, durvalumab, and cabozantinib plus atezolizumab, are probably not cost-effective in comparison with tyrosine kinase inhibitors or other ICIs. The most influential parameters were price of anticancer drugs, hazard ratios for progression-free survival and overall survival, and utility for health statest. Our review demonstrated that ICIs were not a cost-effective intervention in advanced HCC. Although ICIs can significantly enhance the survival of patients with advanced HCC, decision-makers should consider the findings of economic evaluations and affordability before adoption of new therapies.

Abstract
BACKGROUND AND OBJECTIVES Camrelizumab plus rivoceranib showed significant clinical benefits in progression-free survival and overall survival compared to sorafenib in patients with unresectable hepatocellular carcinoma (HCC). This study aimed to assess its cost effectiveness from the perspective of Chinese health care system. METHODS A Markov state-transition model was developed based on the Phase 3 randomized CARES-310 clinical trial data. Health state utility values were obtained from the CARES-310 clinical trial, and direct medical costs were derived from 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 were performed to assess the uncertainty of the model. RESULTS In the base-case analysis, the incremental effectiveness and cost of camrelizumab plus rivoceranib versus sorafenib were 0.41 QALYs and $13,684.84, respectively, resulting in an ICER of $33,619.98/QALY, lower than the willingness-to-pay threshold of China ($35,864.61/QALY). Subgroup analyses revealed that the ICERs of camrelizumab plus rivoceranib versus sorafenib were $35,920.01 and $29,717.98 in patients with ALBI grade 1 and grade 2, respectively. One-way sensitivity analyses indicated that the cost of camrelizumab, the proportion of patients receiving subsequent treatment in the camrelizumab plus rivoceranib group, and the cost of rivoceranib were the most significant factors in the base-case analysis. Probabilistic sensitivity analysis suggested that the probabilities of cost effectiveness of camrelizumab plus rivoceranib were 61.27%, 51.46%, and 82.78% for any grade, and ALBI grade 1 and grade 2, respectively. CONCLUSIONS Camrelizumab plus rivoceranib was more cost effective than sorafenib as first-line therapy for unresectable HCC in the Chinese setting.

Abstract
BACKGROUND The objective of this study was to systematically analyse methodological and structural assumptions utilised in model-based health economic evaluations of systemic advanced hepatocellular carcinoma (HCC) therapies, discuss the existing challenges, and develop methodological recommendations for future models in advanced HCC. METHODS We performed literature searches using five databases (Embase, PubMed, Web of Science, Econlit, and CNKI) up to December 4, 2022. Technology appraisals from Canada, England, Australia, and the United States were also considered. Model-based full economic evaluations of systemic advanced HCC therapies in English or Chinese met the eligibility criteria. The reporting quality was assessed by using the Consolidated Health Economic Evaluation Reporting Standards 2022 checklist. RESULTS Of 12,863 records retrieved, 55 were eligible for inclusion. Markov model (n = 29, 53%) and partitioned survival model (n = 27, 49%) were the most commonly used modelling techniques. Most studies were based on health-state-driven structure (n = 51, 93%), followed by treatment-line-driven structure (n = 2, 4%) and combination structure (n = 1, 2%). Only three studies (5%) adopted external real-world data to extrapolate the overall survival or calibrate the extrapolation. Few studies reported the assumptions of transition probabilities. Utility modelling approaches were state-based (n = 51, 93%) and time-to-death (n = 1, 2%). Only 13 studies (24%) reported five types of model validation. Economic evaluation results of specific treatment strategies varied among studies. CONCLUSIONS Disease modelling for health economic evaluations of systemic therapies in advanced HCC has adopted various modelling approaches and assumptions, leading to marked uncertainties in results. By proposing methodological recommendations, we suggest that future model-based studies for health economic evaluation of HCC therapies should follow good modelling practice guidelines and improve modelling methods to generate reliable health and economic evidence.

Abstract
Introduction The existence of many phase III randomized controlled trials (RCTs) of first-line treatment for unresectable hepatocellular carcinoma (HCC) puzzle doctors and patients in choosing the most effective treatment strategies. We aimed to assess the efficacy, safety, and cost-effectiveness of immunotherapy or targeted therapy as the first-line strategy for unresectable HCC. Methods The included clinical trials were retrieved from PubMed, Embase, the Cochrane library, and Web of Science databases, in which immunotherapy or targeted therapy was regarded as the first-line treatment for unresectable HCC, published in English between January 1, 2010, and September 20, 2022. We conducted a network meta-analysis (NMA) and cost-effectiveness analysis (CEA) from the Chinese payer's perspective. Overall survival (OS), progression-free survival (PFS), the ranks of different treatments using P-score, and adverse events (AEs) were evaluated by NMA. Total costs, life-years (LYs), quality-adjusted life-years (QALYs), and incremental cost-benefit ratio (ICER) were estimated from 15-year Markov models developed by CEA. Results We identified 2,825 records, including 11,796 patients, from 15 RCTs. The NMA revealed that sintilimab plus a bevacizumab biosimilar (HR, 0.57; 95% CI, 0.43 to 0.75; P = 0.96) and camrelizumab plus rivoceranib (HR, 0.56; 95% CI, 0.41 to 0.66; P = 0.94) could lead to great improvements in OS and PFS compared with sorafenib-related survival. The CEA indicated that tislelizumab increased by 0.220 QALYs (0.312 LYs) and decreased by $1,938 compared with sorafenib, which yielded ICERs of -$8,809/QALY (-$2,612/LY). Sensitivity analysis showed that the model was stable. Conclusion Sintilimab plus a bevacizumab biosimilar and camrelizumab plus rivoceranib significantly prolonged OS and PFS, respectively. Further considering the pharmacoeconomics factors, tislelizumab is the most cost-effective first-line treatment strategy for unresectable HCC in China.

Cost-effectiveness of sintilimab plus chemotherapy versus chemotherapy alone as first-line treatment of locally advanced or metastatic oesophageal squamous cell carcinoma.

Abstract
Background Sintilimab plus chemotherapy significantly prolongs overall survival (OS) for patients with advanced or metastatic oesophageal squamous cell carcinoma (OSCC). However, the cost-effectiveness of this high-priced therapy is currently unknown. We evaluated the cost-effectiveness of sintilimab plus chemotherapy vs chemotherapy alone as fist-line therapy in patients with advanced or metastatic OSCC from the perspective of Chinese healthcare system. Methods A partitioned survival model consisting of 3 discrete health states was constructed to assess the cost and effectiveness of sintilimab plus chemotherapy vs chemotherapy as first-line treatment of OSCC. Key clinical data in the model came from the ORIENT-15 trial. Costs and utilities were collected from published sources. Life-years, quality-adjusted life-years (QALYs), incremental cost-effectiveness ratio (ICER), incremental net health benefits (INHB), and incremental net monetary benefits (INMB) were calculated for the two treatment strategies. One-way and probabilistic sensitivity analyses were conducted to account for uncertainty and model stability. Additional subgroup and scenario analyses were performed. Results Treatment with sintilimab plus chemotherapy provided an additional 0.37 QALYs and an incremental cost of $8,046.58 compared with chemotherapy, which resulted in an ICER of $21,782.24 per QALY gained. One-way sensitivity analysis revealed that the model was most sensitive to utility of progression-free survival (PFS) and the cost of sintilimab. The probabilistic sensitivity analysis indicated that the probability of sintilimab plus chemotherapy being cost-effective was 0.01%, 76.80% and 98.60% at the threshold of 1, 2 or 3 times GDP per capita per QALY, respectively. Subgroup analysis found that all subgroups other than PD-L1 expression combined positive scores < 1 subgroup favored sintilimab plus chemotherapy treatment due to its association with positive INHBs by varying the hazard ratios for OS and PFS. The scenario analyses showed altering the time horizon of the model or fitting survival curves separately did not reverse results of the model. Conclusion Sintilimab plus chemotherapy was associated with improved QALYs and an additional cost but was estimated to be cost-effective compared with chemotherapy alone as a first-line treatment for patients with advanced or metastatic OSCC at the commonly adopted willingness-to-pay threshold of 3 times GDP per capita per QALY in China.

Abstract
The standard of care of first-line systemic therapy for advanced hepatocellular carcinoma (HCC) is currently changing with the results of the IMbrave150 trial which are demonstrating superiority of the atezolizumab-bevacizumab combination over sorafenib, modifying this line of treatment for the first time in over 10 years. Recently, other immunotherapy-based combinations (durvalumab-tremelimumab, lenvatinib-pembrolizumab, cabozantinib-atezolizumab, and camrelizumab-rivoceranib) reported results in phase III studies, and might challenge this new standard of care. This revolution will lead to a considerable change in practice, and highlight challenges for future drug development. In this review, we will, firstly, describe results of the different combinations, and discuss the difficulties in selecting the first-line treatment. We will then present the different recommendations about second-line treatment following the first-line immunotherapy-based combination, discussing the rationale for the differences in existing recommendations. We will finally discuss the challenges for future drug development in advanced HCC.

Metformin Enhances the Anti-Cancer Efficacy of Sorafenib via Suppressing MAPK/ERK/Stat3 Axis in Hepatocellular Carcinoma. Int J Mol Sci 2022; 23:ijms23158083.

Abstract
Hepatocellular carcinoma (HCC) incidence, as well as related mortality, has been steadily increasing in the USA and across the globe, partly due to the lack of effective therapeutic options for advanced HCC. Though sorafenib is considered standard-of-care for advanced HCC, it only improves median survival by a few months when compared to placebo. Sorafenib is also associated with several unpleasant side effects that often lead to early abatement of therapy. Here, we investigate whether a combination regimen including low-dose sorafenib and a non-toxic dose of anti-diabetic drug metformin can achieve effective inhibition of HCC. Indeed, combining metformin with low-dose sorafenib inhibited growth, proliferation, migration, and invasion potential of HCC cells. We observed a 5.3- and 1.9-fold increase in sub-G1 population in the combination treatment compared to sorafenib alone. We found that the combination of metformin enhanced the efficacy of sorafenib and inhibited the MAPK/ERK/Stat3 axis. Our in vivo studies corroborated the in vitro findings, and mice harboring HepG2-derived tumors showed effective tumor reduction upon treatment with low-dose sorafenib and metformin combination. This work sheds light on a therapeutic strategy aiming to augment sorafenib efficacy or dose-de-escalation that may prove beneficial in circumventing sorafenib resistance as well as minimizing related side effects.
