瑞齐替尼对比吉非替尼一线治疗EGFR突变阳性晚期非小细胞肺癌的成本-效用分析
Cost-utility analysis of rezivertinib versus gefitinib as first-line treatment for EGFR mutation-positive advanced non-small cell lung cancer
摘要
Abstract
OBJECTIVE To evaluate the cost-effectiveness of rezivertinib versus gefitinib as first-line treatment for epidermal growth factor receptor(EGFR)mutation-positive advanced non-small cell lung cancer(NSCLC)from the perspective of the Chinese healthcare system.METHODS A Markov model was constructed based on the REZOR trial data,with a cycle length of 3 weeks and a study duration of 5 years.Both costs and health outcomes were discounted at an annual rate of 5%.A cost-utility analysis was conducted using 3 times China's 2024 per capita gross domestic product as the willingness-to-pay(WTP)threshold.The economic differences between the rezivertinib regimen versus the gefitinib regimen were evaluated using the incremental cost-effectiveness ratio(ICER)and incremental net monetary benefit(INMB).Sensitivity and scenario analyses were performed to verify the robustness of the model.RESULTS Compared to the gefitinib regimen,the rezivertinib regimen saved 225 310.47 yuan and gained an additional 0.57 quality-adjusted life years(QALYs),resulting in an ICER of-395 562.80 yuan/QALY,which was much lower than the WTP threshold of this study,indicating that rezivertinib had an absolute economic advantage.The INMB analysis(389 041.26 yuan)further validated this conclusion.One-way and probabilistic sensitivity analyses confirmed the robustness of the model.Scenario analysis,incorporating a 15%reduction in drug prices and adjustments to the utility values for progression free survival and progression disease,yielded consistent results with the base case analysis.CONCLUSIONS Compared to gefitinib,rezivertinib as a first-line treatment for EGFR mutation-positive advanced NSCLC has an absolute economic advantage.关键词
