CABOMETYX vs INLYTA
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.
Axitinib is a tyrosine kinase inhibitor that selectively inhibits vascular endothelial growth factor receptors (VEGFR-1, VEGFR-2, and VEGFR-3), which are involved in pathologic angiogenesis, tumor growth, and metastatic progression of cancer.
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.
5 mg orally twice daily, approximately 12 hours apart, with or without food.

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 13–17 hours in patients, supporting twice-daily dosing.
Primarily fecal (54%) with minimal renal excretion (27% unchanged drug; <10% as metabolites). Biliary excretion contributes to fecal elimination.
Primarily hepatic metabolism via CYP3A4 and subsequent biliary-fecal elimination (approximately 61% of dose recovered in feces, 23% in urine as metabolites; <10% excreted unchanged in urine or feces).
