ABSTRACT: Background
Cabozantinib was approved by the European Medicines Agency and the Federal Drug Administration as an option for sorafenib-resistant advanced hepatocellular carcinoma, increasing overall survival and progression-free survival compared with placebo. We evaluated the cost-effectiveness of cabozantinib in the second-line setting for patients with an advanced hepatocellular carcinoma from the German statutory health insurance perspective compared with an US scenario using US prices.Methods
A Markov model was developed to compare the costs and effectiveness of cabozantinib with best supportive care in the second-line treatment of advanced hepatocellular carcinoma over a lifetime horizon. Health outcomes were measured in discounted life years and discounted quality-adjusted life years. Survival probabilities were estimated using parametric survival distributions based on CELESTIAL trial data. Utilities were derived from the literature. Costs contained drugs, monitoring and adverse events measured in US Dollars. Model robustness was addressed in univariable, scenario and probabilistic sensitivity analyses.Results
Cabozantinib generated a gain of 0.18 life years (0.15 quality-adjusted life years) compared with best supportive care. The total mean cost per patient was $56,621 for cabozantinib and $2064 for best supportive care in the German model resulting in incremental cost-effectiveness ratios for cabozantinib of $306,778/life year and $375,470/quality-adjusted life year. Using US prices generated costs of $177,496 for cabozantinib and $4630 for best supportive care and incremental cost-effectiveness ratios of $972,049/life year and $1,189,706/quality-adjusted life year.Conclusions
Our analysis established that assuming a willingness-to-pay threshold of $163,371/life year (quality-adjusted life year) for the German model and $188,559/life year (quality-adjusted life year) for the US model, cabozantinib is not cost-effective compared with best supportive care. Sensitivity analyses showed that cabozantinib was not cost-effective in almost all our scenarios.
