Cost-utility analysis of pembrolizumab combined with chemotherapy in the first-line treatment of advanced or unresectable biliary tract carcinoma
To evaluate the cost-effectiveness of pembrolizumab combined with chemotherapy versus placebo combined with chemotherapy in the first-line treatment of advanced or unresectable biliary tract carcinoma (BTC) from the perspective of China’s health system.
METHODS
2
A partitioned survival model was constructed based on the KEYNOTE-966 study data. The simulation period was 21 days, and the simulation time was the patient’s whole life. Using quality-adjusted life year (QALY) as the output indicator, the cost-utility analysis method was used to evaluate the cost-effectiveness of the two schemes mentioned above. Univariate and probabilistic sensitivity analyses were performed to verify the results of the basic analysis, and to explore the cost-effectiveness under the scenario of drug donation scheme.
RESULTS
2
The basic analysis showed that both the cost and effectiveness of the pembrolizumab group were higher than those of the placebo group, and the incremental cost-effectiveness ratio (ICER) was 3 909 359.78 yuan/QALY, which was higher than the willingness-to-pay (WTP) threshold of 3 times 2022 gross domestic product (GDP) per capita (257 094 yuan), indicating no cost-effectiveness. The results of univariate sensitivity analysis showed that the utility discount rate, the utility value of progression-free survival (PFS) status, the cost discount rate, and the cost of pembrolizumab had a great influence on ICER. Probabilistic sensitivity analysis verified the robustness of the results of basic analysis, and concluded that when the WTP threshold was greater than 1 500 000 yuan/QALY, the pembrolizumab group became cost-effective. The results of the scenario analysis showed that considering the drug donation scheme of pembrolizumab for low-income people, although its treatment cost was significantly reduced, it was still not cost-effective.
CONCLUSIONS
2
At the WTP threshold of 3 times China’s GDP per capita in 2022, pembrolizumab combined with chemotherapy is not cost-effective compared with placebo combined with chemotherapy for advanced or unresectable BTC.
