ABSTRACT
Introduction:
The tyrosine kinase inhibitors regorafenib and cabozantinib remain the mainstay in second-line treatment of advanced hepatocellular carcinoma (HCC). There is currently no clear evidence of superiority in efficacy or safety to guide choice between the two treatments.Methods:
We conducted an anchored matching-adjusted indirect comparison using individual patient data from the RESORCE trial of regorafenib and published aggregate data from the CELESTIAL trial of cabozantinib. Second-line HCC patients with prior sorafenib exposure of ≥3 months were included in the analyses. Hazard ratios (HRs) and restricted mean survival time (RMST) were estimated to quantify differences in overall survival (OS) and progression-free survival (PFS). Safety outcomes compared were rates of grade 3 or 4 adverse events (AEs), occurring in >10% of patients, and discontinuation or dose reduction due to treatment-related AEs.Results:
After matching adjustment for differences in baseline patient characteristics, regorafenib showed a favorable OS (HR, 0.80; 95% CI 0.54, 1.20) and â¼3-month-longer RMST over cabozantinib (RMST difference, 2.76 months; 95% CI -1.03, 6.54), although not statistically significant. For PFS, there was no numerical difference in HR (HR, 1.00; 95% CI 0.68, 1.49) and no clinically meaningful difference based on RMST analyses (RMST difference, -0.59 months; 95% CI -1.83, 0.65). Regorafenib showed a significantly lower incidence of discontinuation (risk difference, -9.2%; 95% CI -17.7%, -0.6%) and dose reductions (-15.2%; 95% CI -29.0%, -1.5%) due to treatment-related AEs (any grade). Regorafenib was also associated with a lower incidence (not statistically significant) of grade 3 or 4 diarrhea (risk difference, -7.1%; 95% CI -14.7%, 0.4%) and fatigue (-6.3%; 95% CI -14.6%, 2.0%).Conclusion:
This indirect treatment comparison suggests, relative to cabozantinib, that regorafenib could be associated with favorable OS (not statistically significant), lower rates of dose reductions and discontinuation due to treatment-related AEs, and lower rates of severe diarrhea and fatigue.
