Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Imatinib mesylate is a tyrosine kinase inhibitor that selectively inhibits BCR-ABL, c-KIT, PDGFR, and other kinases, blocking proliferation and inducing apoptosis in cells expressing these targets.
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.
400 mg orally once daily with a meal and a large glass of water. For advanced GIST, 400 mg daily; for CML in chronic phase, 400 mg daily; for accelerated phase or blast crisis, 600 mg daily. Dose may be increased to 600 mg or 800 mg daily in patients with disease progression.
450 mg orally once daily with food.

Terminal elimination half-life is approximately 18 hours (range 13–20 hours) in healthy subjects; for the active N-desmethyl metabolite, half-life is about 40 hours (range 30–50 hours). Clinical context: Steady-state is achieved within 1–2 weeks; once-daily dosing maintains therapeutic concentrations.
Terminal elimination half-life approximately 12-15 hours in patients, supporting twice-daily dosing.
Primarily fecal (68% of dose) as metabolites; renal excretion accounts for approximately 13% of dose (predominantly as metabolites). Unchanged imatinib in urine is <10%.
Primarily fecal (≥80% of absorbed dose), with renal excretion accounting for <5% as unchanged drug.
