Cost-effectiveness of camrelizumab plus rivoceranib versus sorafenib as first-line treatment of unresectable hepatocellular carcinoma.

BACKGROUND

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related mortality globally. Recent advancements in targeted therapies have improved outcomes for advanced HCC, yet therapeutic options remain limited. The CARES-310 trial demonstrated that camrelizumab plus rivoceranib significantly improves survival compared to sorafenib for advanced HCC.

OBJECTIVES

This study aimed to evaluate the cost-effectiveness of camrelizumab plus rivoceranib as a first-line treatment for unresectable HCC from the Chinese health system perspective.

DESIGN

The cost-effectiveness analysis.

METHODS

A partitioned survival model was constructed to estimate clinical and economic outcomes for patients with unresectable or metastatic HCC. The model included three health states: progression-free, progression disease, and death. The hypothetical cohort consisted of patients aged ⩾18 with HCC who had not received systemic therapy, reflecting the CARES-310 trial. Clinical data were derived from the CARES-310 trial and extrapolated using standard parameter distributions. Direct medical costs and utilities were sourced from the CARES-310 trial and published literature.

RESULTS

The 10-year cost of camrelizumab plus rivoceranib was higher than sorafenib (USD 28,148.01 vs USD 20,997.86). Camrelizumab plus rivoceranib yielded an additional 0.26 quality-adjusted life-years (QALYs) with an incremental cost of USD 7150.15, resulting in an incremental cost-effectiveness ratio of USD 27,633.75/QALY. Sensitivity analyses confirmed the robustness of the base-case results.

CONCLUSION

Camrelizumab plus rivoceranib is likely a cost-effective first-line treatment for unresectable HCC from a Chinese health system perspective. This study highlights the need for additional real-world data to validate these findings and guide clinical decision-making for HCC.
