Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cabozantinib is a small molecule inhibitor of multiple receptor tyrosine kinases, including MET, VEGFR2, RET, AXL, KIT, and FLT3. It inhibits tumor growth, angiogenesis, and metastasis by blocking these pathways.
Multikinase inhibitor that inhibits VEGFR-1, -2, -3, PDGFR-α, PDGFR-β, FGFR-1, -2, TIE2, KIT, RET, RAF-1, and B-RAF.
60 mg orally once daily for the first 21 days of a 21-day cycle, with or without food, for renal cell carcinoma; for hepatocellular carcinoma, 60 mg orally once daily.
160 mg orally once daily for 3 weeks, followed by 1 week off (28-day cycle).

Terminal half-life approximately 99 hours (range 80–120 h). Supports once-daily dosing with steady-state achieved within 15 days.
Terminal elimination half-life is approximately 30 hours (range 15-42 h) for regorafenib and 25-60 h for its active metabolites M-2 and M-5. Steady-state is reached within 2-3 weeks.
Primarily fecal (54%) with minimal renal excretion (27% unchanged drug; <10% as metabolites). Biliary excretion contributes to fecal elimination.
Approximately 51% fecal (as unchanged drug and metabolites), 19% renal (as metabolites, <1% unchanged).
