BOSULIF vs NEXAVAR
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.
Multikinase inhibitor targeting Raf, VEGFR-2, VEGFR-3, PDGFR-β, c-KIT, Flt-3, and RET kinases, inhibiting tumor growth and angiogenesis.
400 mg orally once daily with food.
400 mg (two 200 mg tablets) orally twice daily approximately 12 hours apart on an empty stomach (at least 1 hour before or 2 hours after a meal).

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 25-48 hours; supports twice-daily dosing with steady state achieved in 7-14 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.
Fecal (77% as unchanged drug and metabolites), renal (19% as metabolites, <1% as unchanged drug).
