GILOTRIF vs LENVATINIB
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 kinase inhibitor that inhibits the receptor tyrosine kinases (RTKs) including VEGFR1 (FLT1), VEGFR2 (KDR), VEGFR3 (FLT4), FGFR1, FGFR2, FGFR3, FGFR4, PDGFRα, KIT, and RET. It also inhibits the kinase activities of other RTKs involved in tumor angiogenesis and tumor growth.
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; 8 mg twice daily or 12 mg once daily in combination with everolimus for renal cell carcinoma; 12 mg once daily in combination with pembrolizumab for advanced endometrial carcinoma.

Terminal elimination half-life is approximately 41 hours, supporting once-daily dosing. Steady-state is reached within 8 days.
Approximately 28 hours (range 22-35 hours); supports once-daily dosing with steady-state achieved in ~5-7 days.
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.
Fecal (approximately 64% of dose) and renal (approximately 25% of dose, with <2% as unchanged drug).
