ALUNBRIG vs LENVIMA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Alunbrig (brigatinib) is a tyrosine kinase inhibitor that targets ALK and ROS1. It inhibits autophosphorylation of ALK and ALK-mediated activation of downstream signaling proteins STAT3, AKT, ERK1/2, and PLCγ in ALK-dependent tumor cells.
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.
90 mg orally once daily for first 7 days, then increase to 180 mg orally once daily
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 half-life approximately 25 hours. Supports once-daily dosing; steady state achieved in ~5 days.
Terminal elimination half-life is approximately 28 hours, supporting once-daily dosing.
Primarily hepatic metabolism (CYP3A4); 65% fecal (unchanged and metabolites), 25% renal (1% unchanged). Biliary excretion contributes to fecal elimination.
Approximately 71% of the dose is excreted in feces (34% as unchanged drug) and 25% in urine (0.4% as unchanged).
