General information

Class/mechanism: Tyrosine kinase inhibitor. Erdafitinib inhibits multiple receptor tyrosine kinases (RTKs), including fibroblast growth factor receptors (FGFR) FGFR1, FGFR2, FGFR3, FGFR4, as well as RET, CSF1R, PDGFRA, PDGFRB, FLT4, KIT, and VEGFR2. Erdafitinib inhibits FGFR-related phosphorylation and signal transduction, resulting in inhibition and tumor cell death in FGFR-overexpressing tumor cells.[1][2][3]
