FGFR3-selective kinase inhibitor. On the supplier's IC50 figures it is far more potent against FGFR3 S249C and the S249C/V555M double mutant than against FGFR2 or FGFR1, and it retains activity against FGFR3 gatekeeper mutations, V555M being the relevant resistance substitution. Oncology only, in the FORAGER-2 phase 3.
