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.
Nintedanib is a tyrosine kinase inhibitor that blocks the activity of fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptor (PDGFR), and vascular endothelial growth factor receptor (VEGFR), thereby inhibiting fibroblast proliferation, migration, and transformation, and reducing extracellular matrix deposition.
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.
150 mg orally twice daily, taken 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 is approximately 38 hours (range 30–48 hours) at steady state, supporting once-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 biliary/fecal (~93.4% of total radioactivity recovered in feces), renal excretion is minor (~0.6% unchanged in urine).
