- Abstract
The sustainability and generalizability of China's dynamic zero-COVID strategy on eliminating SARS-CoV-2 transmission has casted doubt globally, mainly because it has exacted high social and economic cost. This study aimed to estimate the disease burden during the first wave of Omicron in China and compared the cost-effectiveness of implementing a Real-world strategy (adjusted dynamic zero-COVID strategy) with two simulated strategies (routine and stricter dynamic zero-COVID strategy) to inform appropriate strategies for COVID-19 pandemic control. A dynamic state-transition simulation model was developed to compare the health and cost outcomes between different dynamic zero-COVID strategies. Omicron-related healthcare costs were estimated from the societal perspective. Epidemiological parameter values were derived from data of real-world or generated by model calibration; costs and effectiveness parameter values were informed either by local data or published literature. The primary outcomes were total social cost, disability adjusted life-years (DALYs) and net monetary benefit (NMB). Deterministic sensitivity analyses (DSA) and scenario analyses were performed to assess the model robustness. The first wave of Omicron in Shanghai resulted in 47,646 DALYs lost and 415 billion RMB losses. At a willingness-to-pay threshold of 173,630 RMB (the GDP per capita of Shanghai in 2021) per DALY saved, the Real-world strategy was considered as the most cost-effective strategy due to its highest NMB (−407 billion). Results from DSA confirmed the robustness of our findings. Our finding supported the Real-world strategy taken by the Shanghai Municipal Government between March 1 and May 21, 2022 to control the first wave of Omicron outbreak. Moreover, our results indicated that whether the Stricter dynamic zero-COVID strategy is worth implementing at the beginning of the COVID-19 outbreak mainly depended on the infection rate of COVID-19 among primary contacts. Our analysis provides important evidence to inform policy makers to make appropriate decisions regarding COVID-19 pandemic management. [ABSTRACT FROM AUTHOR]

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.

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.

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.

Background: An oncology trial compared four cycles of doxorubicin/cyclophosphamide (AC) with four cycles of docetaxel/cyclophosphamide (TC) in operable breast cancer patients (71% were diagnosed with hormone receptor positive and 48% with node-negative breast cancer). The objective of this study was to estimate the lifetime cost effectiveness of AC versus TC, from a Chinese healthcare provider perspective, based on a clinical trial. Abstract: Methods: A lifetime cost-effectiveness analysis was performed using a Markov model. Events rates and utilities in the Markov model were derived from published papers. Data on cost of breast cancer care were obtained from the Second Xiangya Hospital of Central South University, Changsha, PR China. One-way sensitivity analysis and probabilistic sensitivity analysis were undertaken. Cost estimates were valued in Chinese yuan (Y), year 2008 values. All costs and outcomes were discounted at 3% per annum. Abstract: Results: Patients receiving TC gained 14.45 QALYs, 0.41 QALYs more than patients receiving AC. The lifetime costs of patients receiving TC were Y93 511, Y10 116 more than that of AC patients. The incremental cost-effectiveness ratios were Y26 742 per life-year gained (£2719.8 per year) and Y24 305 per QALY gained (£2471.9 per QALY). The most sensitive parameter in the model was the cost of primary cancer treatments in the TC arm. At a threshold willingness to pay of Y86 514 per QALY, the probability of TC being cost effective was 90%. Abstract: Conclusions: Our model suggests that TC may be considered cost effective from a Chinese healthcare provider perspective, according to the threshold defined by the WHO.

Kawasaki disease (KD) after rotavirus and hepatitis A vaccination has not previously been reported in a baby in China. Herein, we describe a 20-month-old child who developed Kawasaki disease after receiving her second dose of Lanzhou lamb rotavirus vaccine (LLR) and her first dose of freeze-dried live attenuated hepatitis A vaccine. The case report was conducted by collecting and analyzing the hospital in-patient medical records and reviewing both the domestic and foreign pertinent literature. These findings will be important to note this possible side effect and to further investigate the association between the above 2 vaccines and Kawasaki disease.

Abstract Background The addition of ribociclib (RIB) to letrozole (LET) significantly increases progression free survival for patients with hormone-receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer (ABC). We identified the range of drug costs for which RIB could be considered cost effective from a Chinese perspective. Methods A discrete event simulation model was developed to model the treatment sequences among patients with ABC. Life years (LYs), quality-adjusted LYs (QALYs) and lifetime costs were estimated. Costs were estimated for Chinese health care systems. Three times the per capita gross domestic product (GDP) of China 2016 ($24,360) and three times the per capita GDP of Beijing city 2016 ($53,384) were used as the willingness-to-pay threshold. Probabilistic sensitivity analyses were performed. Results In the base case analysis, RIB + LET provided an incremental survival benefit of 0.631 LYs and 0.451 QALYs. When RIB costs less than $721 or $1170 per 4 weeks, there was a nearly 90% likelihood that the incremental cost-effectiveness ratio for RIB + LET would be less than $24,360 per QALY or $53,384 per QALY, respectively. Conclusion A value-based price for the cost of RIB is $732 or $1170 per 4 weeks for China and Beijing City, respectively. Our study is helpful to inform the multilateral drug price negotiations in China that may be upcoming for RIB. Highlights • Value-based price of ribociclib is $732 per 4 weeks for China. • Value-based price of ribociclib is $1170 per 4 weeks for Beijing city. • The value-based price of ribociclib is helpful to inform the drug price negotiation.

Background: There is no single standard chemotherapy regimen for elderly patients with advanced gastric cancer (AGC). A phase III trial has confirmed that both capecitabine monotherapy and capecitabine plus oxaliplatin are well tolerated for elderly patients with AGC, but their economic influence in China is unknown. Objective: The purpose of this cost-effectiveness analysis was to estimate the effects of capecitabine monotherapy and capecitabine plus oxaliplatin in elderly patients with AGC on health and economic outcomes in China. Methods: We created a Markov model based on data from a Korean clinical phase III trial to analyze the cost-effectiveness of the treatment of elderly patients in the capecitabine monotherapy (X) group and capecitabine plus oxaliplatin (XELOX) group. The costs were obtained from published reports and the local health system. The utilities were assumed on the basis of the published literature. Costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICER) were estimated. One-way and probabilistic sensitivity analyses (Monte Carlo simulations) were performed. Results: In the cost-effectiveness analysis, X had a lower total cost ($45,731.68) and cost-effectiveness ratio ($65,918.93/QALY). The one-way sensitivity analysis suggested that the most influential parameter was the risk of requiring second-line chemotherapy in XELOX group. The probabilistic sensitivity analysis predicted that the X regimen was cost-effective 100% of the time, given a willingness-to-pay threshold of $26,598. Conclusions: Our findings show that the XELOX regimen is less cost-effective compared to the X regimen for elderly patients with AGC in China from a Chinese healthcare perspective.
