BOSULIF vs TEPMETKO
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.
Tepotinib is a highly selective, ATP-competitive inhibitor of the mesenchymal-epithelial transition (MET) receptor tyrosine kinase, including the MET exon 14 skipping variant. It inhibits MET phosphorylation and downstream signaling pathways, thereby reducing tumor cell proliferation and migration.

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 elimination half-life approximately 12-15 hours in patients, supporting twice-daily dosing.
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 (≥80% of absorbed dose), with renal excretion accounting for <5% as unchanged drug.
