Caboxen 20 mg (Cabozantinib)
CABOXEN 20 capsules contain Ceboa? Nib (S/malate INN equivalent to 20 mg Cabozantinib.
CABOXEN 80 capsule: Each capsule contains Cabozantinib (TS)-malate INN equivalent to 80 mg of Cabozantinib.
Mechanism of Action
In Vida biochemical and/or cellular assays have shown that Cabozantinib inhibits the tyrosine kinase activity of MET, ET, VEGFR-1, -2 and -3, AXL, FiET, PO’21, TYRO3, MeFi, KIT, TFiKB,
FLT-3, and TIE-2. In tumor microenvironments, receptor tyrosine kinases are involved in oncogenes, metastasis, tumor angiogenesis, and drug resistance.
