OBJECTIVE To estimate the cost-utility of sacituzumab govitecan （SG） versus single-agent chemotherapy in the treatment of hormone receptor-positive （HR+）/human epidermal growth factor receptor 2-negative （HER2－） advanced metastatic breast cancer. METHODS From the perspective of the Chinese medical system， a three-state partitioned survival model was constructed to examine the cost-utility of SG versus single-agent chemotherapy based on TROPiCS-02 trial. The cycle length was set to 1 month， and the time horizon was 10 years. The annual discount was 5%. The model output included total costs and quality adjusted life month （QALM）， and incremental cost-effectiveness ratio （ICER） was calculated for cost-utility analysis， by setting willingness-to-pay （WTP） threshold at 3 times gross domestic product （GDP） per capita of China in 2023 （22 340 yuan/QALM）. Univariate sensitivity analyses， probability sensitivity analyses， and scenario analyses were performed to evaluate the robustness of the results and calculate the price threshold when SG had economic advantages. RESULTS SG group gained incremental 4.25 QALM and 561 570 yuan compared with single-agent chemotherapy， which resulted in an ICER of 132 102/QALM that was higher than WTP. The results of the univariate sensitivity analysis showed that the monthly average cost of SG had the greatest impact on the results； the results of probability sensitivity analysis showed that the probability of SG scheme being cost-effective at the WTP threshold was 0. The results of scenario analysis showed that the conclusions of this study were robust under different time horizons （5， 10， 15 years）. The price threshold for SG being cost-effective was 1 344 yuan per 180 mg. CONCLUSIONS Based on the perspective of Chinese medical system， SG appears to be not cost-effective compared with single-agent chemotherapy for HR+/ HER2－ advanced metastatic breast cancer at the price of 8 400 yuan per 180 mg. A substantial price cut should be taken to be cost- effective.
