Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Midostaurin is a multikinase inhibitor that targets FLT3 (FMS-like tyrosine kinase 3), KIT, PDGFRα/β, VEGFR2, and PKC. It inhibits FLT3 receptor signaling and downstream MAPK/ERK and PI3K/AKT pathways, inducing apoptosis in FLT3-mutated 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.
50 mg orally twice daily with food for acute myeloid leukemia (AML) with FLT3 mutation; for advanced systemic mastocytosis, 100 mg orally twice daily.
450 mg orally once daily with food.

The terminal elimination half-life (t½) of midostaurin is approximately 20 hours (range 17–22 h) for the parent drug and slightly longer for its active metabolite CGP52421 (~30 h). This supports twice-daily dosing while maintaining steady-state concentrations.
Terminal elimination half-life approximately 12-15 hours in patients, supporting twice-daily dosing.
Midostaurin is primarily eliminated via feces (approximately 95% of total radioactivity after a single 50 mg oral dose), with <5% excreted in urine. Biliary excretion is the major route for fecal elimination; unchanged midostaurin accounts for <10% of the dose, with the remainder as metabolites.
Primarily fecal (≥80% of absorbed dose), with renal excretion accounting for <5% as unchanged drug.
