Futibatinib (TAS-120) is an orally bioavailable, highly selective, and irreversible FGFR inhibitor, with IC₅₀s of 3.9, 1.3, 1.6, and 8.3 nM for FGFR 1-4, respectively. Futibatinib inhibits mutant and wild-type FGFR2 with similar IC₅₀s (wild-type FGFR2=0.9 nM; V5651=1-3 nM; N550H=3.6 nM; E566G=2.4 nM)^[1][2][3].

Futibatinib (TAS-120) covalently binds to a highly conserved P-loop cysteine residue in the ATP pocket of FGFR^[1].

Futibatinib (TAS-120) (3, 30, 100 mg/kg/day, p.o.) exerts an anti-tumor effect in mice. Futibatinib (TAS-120) shows anti-tumor effect by administering at moderate intervals, such as intermittent administration of every other day dosing and 2 times/week, and reducing the sustained elevation and weight suppression blood phosphorus level, and take a antitumor effective as daily administration^[1].
