GILOTRIF vs LENVIMA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GILOTRIF (afatinib) is an irreversible inhibitor of the ErbB family of tyrosine kinases, including EGFR (ErbB1), HER2 (ErbB2), ErbB3, and ErbB4. It binds covalently to the ATP-binding pocket of the kinase domain, blocking downstream signaling pathways involved in cell proliferation, survival, and angiogenesis.
Lenvatinib is a multikinase inhibitor that targets vascular endothelial growth factor receptors (VEGFR1, VEGFR2, VEGFR3), fibroblast growth factor receptors (FGFR1, FGFR2, FGFR3, FGFR4), platelet-derived growth factor receptor alpha (PDGFRα), KIT, and RET. It inhibits angiogenesis, tumor growth, and progression by blocking these receptor tyrosine kinases.
40 mg orally once daily for first-line treatment of EGFR mutation-positive non-small cell lung cancer; may be increased to 50 mg if tolerated.
24 mg orally once daily for differentiated thyroid carcinoma; 18 mg orally once daily plus everolimus 5 mg orally once daily for renal cell carcinoma; 12 mg orally once daily plus pembrolizumab 200 mg intravenously every 3 weeks for endometrial carcinoma; 8 mg orally once daily (or 10 mg for patients with body weight ≥60 kg) plus pembrolizumab 200 mg intravenously every 3 weeks for hepatocellular carcinoma.

Terminal elimination half-life is approximately 41 hours, supporting once-daily dosing. Steady-state is reached within 8 days.
Terminal elimination half-life is approximately 28 hours, supporting once-daily dosing.
Approximately 88% of the administered dose is eliminated via feces (with 85% as unchanged parent drug), and 8% via urine (with <5% as unchanged drug). Biliary excretion is the primary route for unchanged drug.
Approximately 71% of the dose is excreted in feces (34% as unchanged drug) and 25% in urine (0.4% as unchanged).
