Abstract:
OBJECTIVE To evaluate the cost-effectiveness of sugemalimab in patients with stage Ⅲ non-small cell lung cancer （NSCLC） whose disease had not progressed after concurrent or sequential chemoradiotherapy from the perspective of the Chinese healthcare system. METHODS Based on the GEMSTONE-301 clinical trial，a three-health state partitioned survival model （PartSA） was developed to simulate the progression of disease，with model cycle of 3 weeks and a lifetime time range； the main output indicators of the model were total cost，quality-adjusted life year （QALY），and incremental cost-effectiveness ratio （ICER）； the cost and health output were discounted using 5% discount rate. Using 1-3 times China’s per capita gross domestic product （GDP） in 2022 as the willingness-to-pay （WTP） threshold，the cost-utility analysis method was used for analysis，and sensitivity analysis and scenario analysis were conducted to assess model robustness. RESULTS Compared with placebo，ICER for sugemalimab consolidation therapy was 59 872.57 yuan/QALY，which was less than one time China’s per capita GDP in 2022 （85 698 yuan） as the WTP threshold. The scenario analysis results further confirmed the robustness of the model. The results of single factor sensitivity analysis indicated that the cost of drugs （pembrolizumab，sugemalimab，docetaxel） and the utility value of disease progression status had a significant impact on ICER； the results of the probabilistic sensitivity analysis showed that sugemalimab had 67.2% probability of being cost-effective at one time China’s GDP per capita in 2022 as the WTP threshold； when 20 000 yuan （less than 3 times GDP per capita in China of 257 094 yuan） was used as the WTP threshold，the probability of sugemalimab consolidation therapy being cost-effective was greater than 98%. CONCLUSIONS The consolidation therapy with sugemalimab is cost-effective for stage Ⅲ NSCLC whose disease had not progressed after concurrent or sequential chemoradiotherapy.
