Erdafitinib (JNJ-42756493) (Table 2), a selective angiogenic TKI with high affinity to FGFR-1 (IC50 = 1.2 nM), FGFR-2 (IC50 = 2.5 nM), FGFR-3 (IC50 = 3.0 nM), and FGFR-4 (IC50 = 5.7 nM).461,462 As an FDA-accelerated drug, erdafitinib primarily aims to adult patients with locally advanced or metastatic urothelial cancer who carrying FGFR-2 or FGFR-3 gene mutations after platinum chemotherapy.463 Up to now, several phase II and phase III clinical trials in patients with bladder cancer are still ongoing (NCT03390504, NCT04172675, NCT02365597, NCT02465060, NCT03473743). Here, FGFR3 is linked to urinary bladder cancer.
