ABSTRACT
OBJECTIVE:To evaluate the econo mics of pembrolizumab in the second-line treatment of advanced hepatocellular carcinoma in China. METHODS :From the perspective of Chinese healthcare system ,a three-state PartSA model and Markov model were established ;the cost and utility for the second-line treatment of advanced hepatocellular carcinoma in China were compared between pembrolizumab and placebo. The circulation cycle of the model was 3 weeks and the study time limit was lifetime;one-way sensitivity analysisprobability sensitivity analysis and scenario analysis were used to verify the robustness of the base-case analysis results. RESULTS :PartSA results showed that the ICER for the second-line treatment of advanced hepato- cellular carcinoma with pembrolizumab was 1 266 846.18 yuan/QALY,which is far more than 1-3 times of China ’s per capita GDP in 2020. The results of one-way sensitivity analysis showed that the three parameters that had the greatest impact on ICER were the PFS status utility of the placebo group ,the PFS status utility of the pembrolizumab group ,and the cost of pembrolizumab. The results of probability sensitivity analysis verified the robustness of the base-case analysis. The scenario analysis showed that the treatment cost of pembrolizumab had dropped significantly when the charity donation of pembrolizumab was considered. Although it was still not economical ,ICER was close to 3 times of per capita GDP of China in 2020. When WTP threshold was 1 and 3 times of China ’s per capita GDP ,the economic prices of pabolizumab (100 mg)were 4 157.67 and 5 829.24 yuan,respectively. The results of Markov model were similar to those of PartSA model. CONCLUSIONS :Under the WTP threshold of 1-3 times China ’s per capita GDP in 2020,pembrolizumab is not economical for second-line treatment of advanced hepatocellular carcinoma.
