Cost-utility analysis of bevacizumab combined with erlotinib in the first-line treatment of advanced EGFR mutant non-squamous NSCLC
To evaluate the cost-effectiveness of bevacizumab combined with erlotinib in the first-line treatment of advanced
EGFR
mutant non-squamous non-small cell lung cancer (NSCLC) from the perspective of China’s health system.
METHODS
2
A dynamic Markov model was established based on BEVERLY study data, with a cycle of 3 weeks, a research deadline until 99% of patients die, and an annual discount rate of 5%. The model outputs were total cost, quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER). Taking 3 times China’s per capita gross domestic product (GDP) in 2023 as the willingness-to-pay (WTP) threshold, the cost-utility analysis was used to evaluate the cost-effectiveness of bevacizumab combined with erlotinib (observation group) versus erlotinib alone (control group) in the first-line treatment of advanced
EGFR
mutant non-squamous NSCLC, and the single factor sensitivity analysis and probability sensitivity analysis were used to verify the robustness of the basic analysis results.
RESULTS
2
The results of the basic analysis showed that compared with the erlotinib therapy plan, ICER of bevacizumab combined with erlotinib was 1 452 243.01 yuan/QALY, which was more than 3 times China’s per capita GDP in 2023 (268 074 yuan/QALY) as the WTP threshold, indicating that bevacizumab combined with erlotinib was not cost-effective. The results of single factor sensitivity analysis showed that the cost of bevacizumab, the utility value of progression-free survival and progressed disease status had a great influence on the results. The results of probability sensitivity analysis showed that when the WTP threshold was 1 740 000 yuan/QALY, the probability of cost-effective of bevacizumab combined with erlotinib plan was 50%.
CONCLUSIONS
2
Compared with erlotinib alone, bevacizumab combined with erlotinib is not cost-effective in the first-line treatment of advanced
EGFR
mutant non-squamous NSCLC, when using 3 times China’s per capita GDP in 2023 as the WTP threshold.
