Costo-Efficacia di cabozantinib nel trattamento di seconda linea del tumore a cellule renali metastatico (mRCC) in Italia
Keywords:Cost-effectiveness, Italy, metastatic renal cell carcinoma, second line
AbstractIntroduction: Renal cell carcinoma (RCC) is the most common form of kidney cancer with >30% already metastatic at diagnosis. For patients who fail tyrosine kinase inhibitor (TKI) therapy, the Italian Medical Oncology Association recommends (level IA) nivolumab and cabozantinib. The aim of this study was to compare the cost-effectiveness of cabozantinib with nivolumab for treatment of adult patients with mRCC following prior TKI therapy in Italy. Methods: A partitioned survival (area under the curve) model was developed for the Italian medical environment. Cost-effectiveness was assessed from the Italian National Healthcare Service (SSN) perspective over a 30-year time horizon (annual discount: 3% rate). In the absence of head-to-head studies, clinical evidence was based on results of network meta-analysis. Health-state-related utilities were informed by EQ-5D data from the METEOR study. Resource use and costs were obtained from published sources. Results: Treatment with cabozantinib dominates nivolumab across a 30-years time horizon. In the reference case, treatment with cabozantinib results in an incremental 0.268 quality-adjusted life years (QALY) and an incremental 0.349 life years (LY) gained with a total saving, for the Italian SSN, of €5,605 compared to nivolumab over 30 years. Cabozantinib is associated with gains in quality adjusted life years versus nivolumab, in all analyses. Results were shown to be sensitive to drug prices variation and robust when altering other parameters. Discussion: Cabozantinib represents an efficient option in the management of mRCC after initial TKI-therapy in Italy. Drug prices impact final results, and this must be carefully considered, especially considering the confidential discounts and outcome/financial-based agreements currently in place in Italy.
