NINTEDANIB vs QINLOCK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nintedanib is a small molecule tyrosine kinase inhibitor that inhibits multiple receptor tyrosine kinases, including vascular endothelial growth factor receptors (VEGFR-1, VEGFR-2, VEGFR-3), platelet-derived growth factor receptors (PDGFR-α, PDGFR-β), and fibroblast growth factor receptors (FGFR-1, FGFR-2, FGFR-3). It also inhibits RET, FLT3, and Src family kinases. These receptors are involved in angiogenesis, proliferation, and fibrosis.
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.

Terminal half-life: 9.5 hours (range 6-14 hours) in patients with IPF; supports twice-daily dosing.
Terminal elimination half-life is approximately 15 hours (range 11–20 hours) in patients with advanced GIST. This supports twice-daily dosing.
Primarily fecal (85%) as unchanged drug; renal excretion accounts for <1%.
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%).
