Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Multikinase inhibitor that inhibits VEGFR-1, -2, -3, PDGFR-α, PDGFR-β, FGFR-1, -2, TIE2, KIT, RET, RAF-1, and B-RAF.
Selective tyrosine kinase inhibitor targeting ALK, ROS1, and MET, inhibiting downstream signaling pathways (PI3K/AKT, MAPK/ERK) leading to reduced tumor cell proliferation and survival.
160 mg orally once daily for 3 weeks, followed by 1 week off (28-day cycle).

Terminal elimination half-life is approximately 30 hours (range 15-42 h) for regorafenib and 25-60 h for its active metabolites M-2 and M-5. Steady-state is reached within 2-3 weeks.
Terminal elimination half-life is approximately 72 hours (range 47-108 hours) in patients, supporting once-daily dosing.
Approximately 51% fecal (as unchanged drug and metabolites), 19% renal (as metabolites, <1% unchanged).
Primarily hepatic metabolism, with 53% of the dose recovered in feces (mostly as metabolites) and 22% in urine (1.1% unchanged).
