RESUMO
Background: High prices of anticancer drugs have raised concerns due to their financial impact on patients and healthcare systems. This study aimed to assess the initial and latest list prices and clinical value of reimbursed anticancer drugs in China, Japan, and South Korea. Methods: We identified anticancer drugs newly approved by the National Medical Products Administration of China from January 2012 to June 2022, and by the Pharmaceuticals and Medical Devices Agency of Japan and the Ministry of Food and Drug Safety of South Korea up until June 2022. We compared initial and latest treatment prices between countries and assessed clinical value using patients' survival, quality of life (QoL), and European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS). We calculated Spearman rank correlation coefficients of treatment prices with clinical value for individual countries and employed regression analyses to investigate whether the relationship between prices and clinical value was modified by the country setting. Findings: Our cohort included 91 anticancer drug indications, with 60 listed for reimbursement in China, 91 in Japan, and 87 in South Korea. Median treatment prices were highest in Japan, followed by South Korea, and lowest in China, both for initial prices (US$64082 vs. US$45529 vs. US$19144, p < 0.0001) and latest prices (US$50859 vs. US$31611 vs. US$18666, p < 0.0001). Over time, China (ß = -0.047, p < 0.0001) and South Korea (ß = -0.049, p < 0.0001) witnessed more significant price reductions compared to Japan (ß = -0.013, p = 0.011). The correlations between both initial and latest treatment prices and clinical value (QoL and ESMO-MCBS) were more significant and stronger in China and South Korea than in Japan, although Japan exhibited slightly stronger correlations in terms of survival compared to China and South Korea. The relationship between clinical value and treatment prices may not be modified by the country setting. Interpretation: In comparison, South Korea's list prices and their correlations with clinical value appear reasonable. Policymakers in Japan could enhance efficiency by controlling prices and aligning them with clinical value, while China would need to take substantial steps to expand anticancer drug coverage.

RESUMO
BACKGROUND: The potential role played by launch price and clinical value in reimbursement decisions has not been sufficiently established in China. This study aimed to investigate the association of launch price and clinical value with reimbursement decisions for anticancer drugs after the implementation of reimbursement-linked price negotiation in China. METHODS: Anticancer drugs approved by the National Medical Products Administration (NMPA) of China from January 2017 to June 2022 were eligible for inclusion. Approval and reimbursement dates of included drug indications were retrieved from publicly available resources. We collected measures of clinical value, including survival, quality of life (QoL), and overall response rate from pivotal clinical trials and calculated treatment price at launch. Univariate and multivariate Cox proportional hazards models were employed to estimate the association between launch price, clinical value, and reimbursement decisions of anticancer drugs in China. RESULTS: The median reimbursement lag was 579 days (interquartile range [IQR]: 402-936) for 93 indications supported by randomized controlled trials and 637 days (IQR: 373-858) for 42 indications supported by single-arm clinical trials. Reimbursement was granted to 60 (65%) and 23 (55%) indications supported by randomized controlled and single-arm clinical trials, respectively. The launch price of anticancer drugs was not associated with reimbursement decisions in multivariate regression analyses. Indications supported by randomized controlled trials with higher clinical value were more likely to be reimbursed (hazard ratio [HR] for survival=1.07, 95% CI: 1.00-1.15, P=.037), while the overall response rate of indications supported by single-arm clinical trials was not associated with the likelihood of being reimbursed (HR=2.09, 95% CI: 0.14-32.28, P=.595). CONCLUSION: The launch price of anticancer drugs may not have a significant impact on reimbursement decisions, while the implementation of reimbursement-linked price negotiation in China has prioritized anticancer drugs with higher clinical value, but only for indications supported by randomized controlled trials. Efforts are needed to prioritize indications supported by single-arm clinical trials that have higher value during the process of price negotiation.

BACKGROUND: While China has implemented reimbursement-linked drug price negotiation annually since 2017, emphasizing value-based pricing to achieve a value-based strategic purchase of medical insurance, whether drug prices became better aligned with clinical value after price negotiation has not been sufficiently established. This study aimed to assess the changes in prices and their relationship with the clinical value of anticancer drugs after the implementation of price negotiations in China. METHODS AND FINDINGS: In this observational study, anticancer drug indications that were negotiated successfully between 2017 and 2022 were identified through National Reimbursement Drug Lists (NRDL) of China. We excluded extensions of indications for drugs already listed in the NRDL, indications for pediatric use, and indications lacking corresponding clinical trials. We identified pivotal clinical trials for included indications by consulting review reports or drug labels issued by the Center for Drug Evaluation, National Medical Products Administration. We calculated treatment costs as outcome measures based on publicly available prices and collected data on clinical value including safety, survival, quality of life, and overall response rate (ORR) from publications of pivotal clinical trials. The associations between drug costs and clinical value, both before and after negotiation, were analyzed using regression analyses. We also examined whether price negotiation has led to a reduction in the variation of treatment costs for a given value. We included 103 anticancer drug indications, primarily for the treatment of blood cancer, lung cancer, and breast cancer, with 76 supported by randomized controlled trials and 27 supported by single-arm clinical trials. The median treatment costs over the entire sample have been reduced from US$34,460.72 (interquartile range (IQR): 19,990.49 to 55,441.66) to US$13,688.79 (IQR: 7,746.97 to 21,750.97) after price negotiation (P < 0.001). Before price negotiation, each additional month of survival gained was associated with an increase in treatment costs of 3.4% (95% confidence interval (CI) [2.1, 4.8], P < 0.001) for indications supported by randomized controlled trials, and a 10% increase in ORR was associated with a 6.0% (95% CI [1.6, 10.3], P = 0.009) increase in treatment costs for indications supported by single-arm clinical trials. After price negotiation, the associations between costs and clinical value may not have changed significantly, but the variation of drug costs for a given value was reduced. Study limitations include the lack of transparency in official data, missing data on clinical value, and a limited sample size. CONCLUSIONS: In this study, we found that the implementation of price negotiation in China has led to drug pricing better aligned with clinical value for anticancer drugs even after substantial price reductions. The achievements made in China could shed light on the price regulation in other countries, particularly those with limited resources and increasing drug expenditures.
