Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bosutinib is a tyrosine kinase inhibitor that targets BCR-ABL kinase, as well as SRC family kinases. It inhibits the phosphorylation of tyrosine residues in proteins involved in the BCR-ABL signaling pathway, thereby inhibiting cell proliferation and inducing apoptosis in Philadelphia chromosome-positive (Ph+) leukemia cells.
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.
400 mg orally once daily with food.
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.

The terminal elimination half-life is approximately 22.5 hours (range 15-34 hours) following a 500 mg oral dose. This supports once-daily dosing, with steady-state achieved within 15 days.
Terminal half-life approximately 99 hours (range 80–120 h). Supports once-daily dosing with steady-state achieved within 15 days.
Primarily fecal (approximately 85% of the administered dose), with renal excretion accounting for less than 1% as unchanged drug and 3% as metabolites. Biliary excretion is a significant route for elimination of unchanged drug and metabolites.
Primarily fecal (54%) with minimal renal excretion (27% unchanged drug; <10% as metabolites). Biliary excretion contributes to fecal elimination.
