Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Entrectinib is a potent inhibitor of tropomyosin receptor tyrosine kinases (TRK) A, B, and C, and also inhibits ROS1 and ALK. It blocks downstream signaling pathways including MAPK, PI3K/AKT, and PLCγ, leading to apoptosis and reduced tumor growth in cancers with NTRK or ROS1 fusions.
Multikinase inhibitor that inhibits VEGFR-1, -2, -3, PDGFR-α, PDGFR-β, FGFR-1, -2, TIE2, KIT, RET, RAF-1, and B-RAF.
200 mg orally once daily with or without food.
160 mg orally once daily for 3 weeks, followed by 1 week off (28-day cycle).

Terminal half-life approximately 24 hours; supports once-daily dosing, steady-state reached in ~5 days.
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.
Primarily hepatic metabolism via CYP3A4; 63% of dose recovered in feces (mostly as metabolites), 18% in urine (9% unchanged).
Approximately 51% fecal (as unchanged drug and metabolites), 19% renal (as metabolites, <1% unchanged).
