Cost-effectiveness analysis of Atezolizumab plus bevacizumab vs. Rivoceranib plus Camrelizumab as first-line treatment for unresectable hepatocellular carcinoma.

BACKGROUND

This study evaluated the cost-effectiveness of Atezolizumab plus Bevacizumab versus Rivoceranib plus Camrelizumab as first-line treatment of unresectable hepatocellular carcinoma (HCC) from the perspective of healthcare payers in China.

METHODS

An economic evaluation using a 3-state partitioned survival model assessed the cost-effectiveness of Atezolizumab plus Bevacizumab versus Rivoceranib plus Camrelizumab. The Kaplan-Meier curves for overall survival (OS) and progression-free survival (PFS) from two clinical trials were digitally extracted, and the Weibull models were applied at the end of the trials to extrapolate long-term survival. The cost and health utility data were sourced from the published literature.

RESULTS

The anticipated cost for Atezolizumab plus Bevacizumab exceeded that for Rivoceranib plus Camrelizumab (109,555.94 USD vs. 15,264.92 USD). The estimated utility for Atezolizumab plus Bevacizumab was decreased compared to that of Rivoceranib plus Camrelizumab (1.47 QALYs vs. 1.59 QALYs). The ICER was -742,858.34 USD/QALY, suggesting the Rivoceranib plus Camrelizumab treatment was cost-effective compared to Atezolizumab plus Bevacizumab as the first-line treatment for advanced or metastatic HCC patients.

CONCLUSION

Rivoceranib plus Camrelizumab was cost-effective compared to Atezolizumab plus Bevacizumab as a first-line treatment for advanced or metastatic HCC patients in China.
