Abstract

Objectives: This study evaluates the cost-effectiveness of adagrasib plus cetuximab in contrast to adagrasib monotherapy in treating colorectal cancer (CRC) patients with mutated KRAS^G12C from the perspective of healthcare payers in the USA.

Methods: An economic evaluation utilizing a 3-state partitioned survival model assessed the cost-effectiveness of adagrasib plus cetuximab versus adagrasib monotherapy. The Kaplan-Meier curves for overall survival (OS) and progression-free survival (PFS) from a clinical trial were digitally extracted, and the Log-Logistic model was employed at the end of the trial to extrapolate the long-term survivals.

Results: The estimated cost for adagrasib plus cetuximab treatment was higher than that of adagrasib monotherapy (290,645.434 USD vs 188,837.346 USD). The estimated utility was decreased compared to that of adagrasib monotherapy treatment (1.094 QALYs vs 1.359 QALYs). The ICER was calculated at -384,674.32 USD/QALY, suggesting the adagrasib plus cetuximab therapy did not demonstrate an economic advantage over adagrasib monotherapy for CRC patients with mutated KRAS^G12C.

Conclusion: Adagrasib plus cetuximab was not cost-effective compared to adagrasib monotherapy as a late-line treatment for advanced or metastatic CRC patients with mutated KRAS^G12C in the USA.

阿达格拉西联合或不联合西妥昔单抗治疗KRAS G12C突变的结直肠癌患者的成本-效果分析

目的：本研究从美国医疗保健支付款人的角度评估阿达格拉西联合西妥昔单药治疗KRASG12C突变的结直肠癌（CRC）患者的成本-效果，与阿达格拉西单药相比。方法：利用3状态分区生存模型进行经济评估，评估阿达格拉西联合西妥昔单药与阿达格拉西单药治疗的成本-效果。从临床试验中提取总生存期（OS）和无进展生存期（PFS）的Kaplan-Meier曲线，并在试验结束时采用Log-Logistic模型来推断长期生存期。结果：阿达格拉西联合西妥昔单抗治疗的估计成本高于阿达格拉西单药治疗（290,645.434美元vs 188,837.346美元）。与阿达格昔单药治疗相比，估计效用下降（1.094 QALYs vs 1.359 QALYs）。ICER的计算值为-384,674.32美元/QALY，表明阿达格拉西联合西妥昔单抗治疗对于KRASG12C突变的结直肠癌患者没有表现出优于阿达格拉西单药治疗的经济优势。结论：在美国，与阿达格拉西单药治疗相比，阿达格拉西联合西妥昔治疗晚期或转移性KRASG12C突变的结直肠癌患者的成本效益不高
