BACKGROUND: Nivolumab improves overall survival (OS) and is associated with less adverse events (AE) compared with sorafenib in the first-line treatment of advanced hepatocellular carcinoma (HCC). But which approach is the most cost-effective remains uncertain. This study aimed to evaluate the cost-effectiveness of nivolumab vs sorafenib as first-line therapy for patients with advanced HCC from the perspective of Chinese healthcare system.
METHODS: A partitioned survival mode was constructed to evaluate the health and economic outcomes of nivolumab vs sorafenib as first-line treatment for advanced HCC. The clinical data and outcomes were obtained from CheckMate 459 trial. Medical costs and utilities were collected from published sources. Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) were calculated. One-way and probabilistic sensitivity analyses were used to examine model uncertainty. Additional subgroup and scenario analyses were performed.
RESULTS: Treatment with nivolumab yielded an additional 0.27 QALYs with an incremental cost of $65,579.19 compared with sorafenib, leading to an ICER of $236,765.93/QALY in China. One-way sensitivity analysis found the model outputs to be most affected for hazard ratio (HR) of OS and the cost of nivolumab. Probabilistic sensitivity analysis showed that the probability of nivolumab being cost-effective was 0% at the willingness-to-pay (WTP) threshold of $38,201.19/QALY. The scenario analyses indicated altering the time horizon of the model did not reverse the economic results.
CONCLUSION: Nivolumab as first-line treatment could gain more health benefits for advanced HCC compared with sorafenib, but was estimated not to be cost-effective at the commonly adopted WTP threshold of China.
