Strahlenther Onkol 2024; 200:805-814. [PMID: 38829437 DOI: 10.1007/s00066-024-02242-6] [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: 12/12/2023] [Accepted: 05/01/2024] [Indexed: 06/05/2024]
Abstract
BACKGROUND Bevacizumab shows superior efficacy in cerebral radiation necrosis (CRN) therapy, but its economic burden remains heavy due to the high drug price. This study aims to evaluate the cost-effectiveness of bevacizumab for CRN treatment from the Chinese payers' perspective. METHODS A decision tree model was developed to compare the costs and health outcomes of bevacizumab and corticosteroids for CRN therapy. Efficacy and safety data were derived from the NCT01621880 trial, which compared the effectiveness and safety of bevacizumab monotherapy with corticosteroids for CRN in nasopharyngeal cancer patients, and demonstrated that bevacizumab invoked a significantly higher response than corticosteroids (65.5% vs. 31.5%, P < 0.001) with no significant differences in adverse events between two groups. The utility value of the "non-recurrence" status was derived from real-world data. Costs and other utility values were collected from an authoritative Chinese network database and published literature. The primary outcomes were total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). The uncertainty of the model was evaluated via one-way and probabilistic sensitivity analyses. RESULTS Bevacizumab treatment added 0.12 (0.48 vs. 0.36) QALYs compared to corticosteroid therapy, along with incremental costs of $ 2010 ($ 4260 vs. $ 2160). The resultant ICER was $ 16,866/QALY, which was lower than the willingness-to-pay threshold of $ 38,223/QALY in China. The price of bevacizumab, body weight, and the utility value of recurrence status were the key influential parameters for ICER. Probabilistic sensitivity analysis revealed that the probability of bevacizumab being cost-effectiveness was 84.9%. CONCLUSION Compared with corticosteroids, bevacizumab is an economical option for CRN treatment in China.

Is bevacizumab a cost‑effective regimen for treating cerebral radiation necrosis in the United States?: Cost-effectiveness analysis of radionecrosis medications. Pract Radiat Oncol 2024:S1879-8500(24)00210-8. [PMID: 39216726 DOI: 10.1016/j.prro.2024.08.003] [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: 04/12/2024] [Revised: 08/01/2024] [Accepted: 08/01/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Bevacizumab has been demonstrated to have superior efficacy in the treatment of cerebral radiation necrosis (CRN), but its' high cost may exacerbate the disease burden. This study aimed to assess the cost-effectiveness of bevacizumab in comparison with corticosteroids for treating CRN from the US payers' perspective. METHODS Decision tree models were constructed to simulate the process of bevacizumab and corticosteroids in CRN short-term and long-term therapy. Critical clinical data were derived from the NCT01621880 trial. Costs and utility values were obtained from the US official websites and published literatures. The main outcomes were total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were performed to assess the robustness of models. RESULTS In the short-term and long-term models, bevacizumab added 0.11 (0.46 vs 0.35) and 0.16 (0.54 vs 0.38) QALYs compared with corticosteroids therapy, with corresponding incremental costs of $12,351 and $23,253, respectively. The resultant ICERs were $112,987/QALY and $150,245/QALY for short-term and long-term treatment, respectively. The one-way sensitivity analysis indicated that utility value of non-recurrence status, body weight and bevacizumab price per cycle were the most influential factors for ICER of both models. At the willingness-to-pay threshold of $150,000/QALY in the US, the probabilities of bevacizumab being cost-effective for CRN short and long-term treatment were 63.9% and 49%, respectively. CONCLUSION Compared with corticosteroids, bevacizumab is an economical alternative for CRN short-term treatment from the US payers' perspective, while long-term therapy draws an opposite conclusion.

BMJ Glob Health 2023; 8:e012780. [PMID: 38030227 PMCID: PMC10689407 DOI: 10.1136/bmjgh-2023-012780] [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: 05/07/2023] [Accepted: 10/31/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND China's National Reimbursement Drug List (NRDL) has become the primary route for drug reimbursement in China. More recently, the authority has made pharmacoeconomic evaluation an integral part of the application for NRDL inclusion. The underlying financial conflict of interests (FCOI) of pharmacoeconomic evaluations, however, has the potential to influence evidence generated and thus subsequent decision-making yet remains poorly understood. METHODS We searched for studies published between January 2012 and January 2022 on the 174 drugs added to the 2017-2020 NRDLs after successful negotiation. We categorised the study's FCOI status into no funding, industry funding, non-profit funding and multiple fundings based on authors' disclosure and assessed the reporting quality of included studies using the Consolidated Health Economic Evaluation Reporting Standards 2022 checklist. We compiled descriptive statistics of funding types and study outcomes using t-tests and χ2 tests and conducted multivariate regression analysis. RESULTS We identified 378 records and our final sample included 92 pharmacoeconomic evaluations, among which 69.6% were conducted with at least one funding source. More than half (57.6%) of the evaluations reached favourable conclusions towards the intervention drug and 12.6% reached a dominant result of the intervention drug over the comparison from model simulation. The reporting quality of included studies ranged from 19 to 25 (on a scale of 28), with an average of 22.3. The statistical tests indicated that industry-funded studies were significantly more likely to conclude that the intervention therapy was economical (p<0.01) and had a significantly higher proportion of resulting target drug economically dominated the comparison drug (p<0.05). CONCLUSION The study revealed that FCOI bias is common in published pharmacoeconomic evaluations conducted in Chinese settings and could significantly influence the study's economical results and conclusions through various mechanisms. Multifaceted efforts are needed to improve transparency, comparability and reporting standardisation.

Clin Genitourin Cancer 2023; 21:8-15. [PMID: 36328903 DOI: 10.1016/j.clgc.2022.10.001] [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: 01/26/2022] [Accepted: 10/02/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND Recently, a clinical trial (NCT02603432) showed that avelumab maintenance treatment, post first-line chemotherapy, can significantly prolong the overall survival of patients with advanced urothelial carcinoma (UC), however, the treatment was very expensive. This study aimed to determine the cost-effectiveness of avelumab maintenance therapy in advanced or metastatic UC from the US taxpayer perspective. METHODS Based on the data of the JAVELIN Bladder 100 clinical trial (NCT02603432), a Markov multi-state model was constructed to investigate the costs and clinical outcomes of avelumab maintenance after platinum-based chemotherapy versus best supportive care (BSC) for advanced or metastatic UC. Parameters of the model came from the 2020 Average Sales Price Drug Pricing Files and published literature. The main outputs were costs, life years (LYs), quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER). Robustness was tested by deterministic and probabilistic sensitivity analyses. The analysis was stratified to include both the overall population and a subset of programmed death-ligand 1 (PD-L1)-positive patients. RESULTS Avelumab maintenance therapy was estimated to generate an additional 0.26 QALYs (1.46 vs. 1.20 QALYs) and costs $183,271 ($278,323 vs. $95,052) more compared to BSC alone in the overall population, yielding an ICER of $699,065/QALY. For the PD-L1-positive population, avelumab produced a 0.42 increase in QALYs (1.74 vs. 1.32 QALYs) and raised costs to $223,238 ($320,355 vs. $97,117), resulting in an ICER of $521,850/QALY for this population. Both ICERs were above the willingness-to-pay (WTP) threshold of $200,000/QALY. Sensitivity analyses manifested that the model was robust. CONCLUSION From the perspective of the US taxpayer, avelumab maintenance therapy is considered cost-ineffective for patients with advanced or metastatic UC at a WTP threshold of $200,000/QALY in the overall population as well as in PD-L1-positive population.

Abstract
Objective Results of Orient 15 indicated the health benefits to patients with local advanced or metastatic oesophageal squamous cell carcinoma (OSCC). This study aimed to evaluate the cost-effectiveness of sintilimab plus chemotherapy in treating OSCC from the perspective of Chinese healthcare system. Methods A partitioned survival model was constructed to evaluate the cost-effectiveness of sintilimab plus chemotherapy vs. chemotherapy in treating OSCC. Baseline characteristics of patients and key clinical data were extracted from Orient 15. Costs and utilities were collected from published studies and open-access databases. Costs, quality-adjusted life-years (QALYs), life-years gained, and incremental cost-effectiveness ratios (ICER) were chosen as economic outcome indicators. We also performed sensitivity analyses and subgroup analyses to verify the stability of results. Results Combination therapy provided additional 0.84 QALYs and 1.46 life-years with an incremental cost of $25,565.48 than chemotherapy, which had an ICER of $30,409.44 per QALY. The probabilistic sensitivity analysis indicated that combination therapy had a 98.8% probability of cost-effectiveness at the willingness-to-pay threshold (WTP) of $38,184 per QALY. Deterministic sensitivity analysis showed that model outcomes were sensitive to the utilities of progression-free survival and progression disease. The subgroup analysis revealed that combination therapy was cost-effective in patients with high expression of PD-L1 and several specific subgroups. Conclusion In this economic evaluation, sintilimab plus chemotherapy was likely to be cost-effective compared with chemotherapy in the first-line therapy of advanced OSCC from the perspective of Chinese healthcare system. Our findings may provide evidence for clinicians to make optimal decisions in clinical practice and for decision-makers to evaluate the cost-effectiveness of sintilimab.

Abstract
BACKGROUND The effectiveness of Sacituzumab Govitecan (SG) for metastatic triple-negative breast cancer (mTNBC) has been demonstrated. We aimed to evaluate its cost-effectiveness on mTNBC from the Chinese and United States (US) perspective. METHODS A partitioned survival model was developed to compare the cost and effectiveness of SG versus single-agent chemotherapy based on clinical data from the ASCENT phase 3 randomized trial. Cost and utility data were obtained from the literature. The incremental cost-effectiveness ratio (ICER) was measured, and one-way and probabilistic sensitivity analyses (PSA) were performed to observe model stability. A Markov model was constructed to validate the results. RESULTS In China, SG yielded an additional 0.35 quality-adjusted life-year (QALY) at an additional cost of Chinese Renminbi ¥2257842. The ICER was ¥6375856 ($924037)/QALY. In the US, SG yielded the same additional QALY at an extra cost of $175393 and the ICER was $494479/QALY. Similar results were obtained from the Markov model. One-way sensitivity analyses showed that SG price had the greatest impact on the ICER. PSA showed the probability of SG to be cost-effective when compared with chemotherapy was zero at the current willing-to-pay threshold of ¥217341/QALY and $150000/QALY in China and the US, respectively. The probability of cost-effectiveness of SG would approximate 50% if its price was reduced to ¥10.44/mg in China and $3.65/mg in the US. CONCLUSION SG is unlikely to be a cost-effective treatment of mTNBC at the current price both in China and the US.
