To evaluate the cost-effectiveness of addition of fruquintinib to best supportive care (BSC) in third-line treatment for patients with metastatic colorectal cancer (CRC).
To conduct the cost-effectiveness analysis, a Markov model was established to simulate the course of metastatic CRC. Three health states-progression-free survival (PFS), progressive disease (PD), and death-were included. Clinical data were derived from the FRESCO trial and health utility values were extracted from previous literature. The primary outcome of the study was incremental cost-effectiveness ratio (ICER) in US dollars per quality-adjusted life-years (QALYs) from a Chinese societal perspective. One-way sensitivity analyses and probabilistic sensitivity analyses were performed to test the robustness of the study.
Addition of fruquintinib to BSC gained 0.54 QALY at a cost of $15,404.57 while the BSC group gained 0.38 QALY at a cost of $9603.94. ICER of fruquintinib versus BSC was $36,253.94/QALY. In the 1-way sensitivity analyses, utility for PD in both groups, utility for PFS in both groups, and cost of fruquintinib significantly influenced the results of the analysis. At the willingness-to-pay threshold of $28,988.40/QALY, probabilities of addition of fruquintinib to BSC or BSC alone as the cost-effective option were 0% and 100%, indicating addition of fruquintinib is not a dominant option compared with BSC.
Addition of fruquintinib to BSC is not a cost-effective regimen in the third-line setting for patients with metastatic CRC from the Chinese societal perspective.
评估在转移性结直肠癌(CRC)患者的三线治疗中,在最佳支持治疗(BSC)基础上加用呋喹替尼的成本效益。
为进行成本效益分析,建立了一个马尔可夫模型来模拟转移性CRC的病程。纳入了三个健康状态——无进展生存期(PFS)、疾病进展(PD)和死亡。临床数据来源于FRESCO试验,健康效用值从既往文献中提取。本研究的主要结局是从中国社会角度计算的每质量调整生命年(QALY)的增量成本效益比(ICER),单位为美元。进行了单向敏感性分析和概率敏感性分析以检验研究的稳健性。
在BSC基础上加用呋喹替尼获得了0.54个QALY,成本为15404.57美元,而BSC组获得了0.38个QALY,成本为9603.94美元。呋喹替尼与BSC相比的ICER为36253.94美元/QALY。在单向敏感性分析中,两组中PD的效用、两组中PFS的效用以及呋喹替尼的成本对分析结果有显著影响。在支付意愿阈值为28988.40美元/QALY时,在BSC基础上加用呋喹替尼或仅采用BSC作为成本效益方案的概率分别为0%和100%,这表明与BSC相比,加用呋喹替尼不是一个占优选择。
从中国社会角度来看,在转移性CRC患者的三线治疗中,在BSC基础上加用呋喹替尼不是一个具有成本效益的方案。
