An approved irreversibly binding FGFR inhibitor 1
The MOA of LYTGOBI inhibits FGFR kinase activity1,2
LYTGOBI, a tyrosine kinase inhibitor, shows targeted antitumor activity against FGFR-deregulated tumors2-5
LYTGOBI is a unique treatment in that it covalently binds in the FGFR kinase domain at sites not targeted by reversible ATP-competitive FGFR inhibitors1,2,6
ATP=adenosine triphosphate; CCA=cholangiocarcinoma; FGF=fibroblast growth factor; FGFR=fibroblast growth factor receptor; iCCA=intrahepatic cholangiocarcinoma; MOA=mechanism of action.
