Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Ripretinib is a switch-control tyrosine kinase inhibitor that inhibits KIT proto-oncogene receptor tyrosine kinase (KIT) and platelet-derived growth factor receptor alpha (PDGFRA) kinase signaling. It binds to both the switch pocket and the activation loop of KIT and PDGFRA, preventing kinase activation and inhibiting downstream signaling pathways involved in tumor cell proliferation and survival.
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.
150 mg orally once daily with food, until disease progression or unacceptable toxicity.

Terminal elimination half-life is approximately 28 hours, supporting once-daily dosing.
Terminal elimination half-life is approximately 15 hours (range 11–20 hours) in patients with advanced GIST. This supports twice-daily dosing.
Approximately 71% of the dose is excreted in feces (34% as unchanged drug) and 25% in urine (0.4% as unchanged).
Primarily hepatic metabolism, with <1% excreted unchanged in urine. Fecal excretion accounts for approximately 80% of the administered dose, with renal excretion of unchanged drug being minimal (<1%).
