Cost-Effectiveness Analysis of First-Line Nivolumab Plus Cabozantinib for Advanced Renal Cell Carcinoma in the United States.

INTRODUCTION

Nivolumab plus cabozantinib improved progression-free survival and overall survival compared with sunitinib in the first-line treatment of advanced renal cell carcinoma (RCC) according to CheckMate 9ER study.

METHODS

A Markov model was developed to compare the costs and effectiveness of nivolumab plus cabozantinib with those of sunitinib in the first-line treatment of advanced RCC. Primary outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). Model uncertainty was assessed in univariable and probabilistic sensitivity analyses.

RESULTS

The total cost per patient was $681,425 for nivolumab plus cabozantinib and $256,302 for sunitinib. The incremental QALY for nivolumab plus cabozantinib was 0.49 compared with sunitinib. The ICER for nivolumab plus cabozantinib was $863,720 per QALY gained versus sunitinib. The results remained robust in univariable and probabilistic sensitivity analyses.

CONCLUSIONS

On the basis of a willingness-to-pay threshold of $150,000, nivolumab plus cabozantinib was not cost-effective under current drug pricing in the first-line treatment of advanced RCC from a US payer's perspective.
