Fibroblast growth factor receptor 4 (FGFR4) is the receptor for fibroblast growth factor 19 (FGF19), which is a tightly controlled hormone that regulates bile acid synthesis and hepatocyte proliferation in the normal liver. Aberrant signaling through the FGFR4/FGF19 signaling complex has been implicated in hepatocellular carcinoma (HCC). BLU-9931 is a small molecule inhibitor of FGFR4 (IC₅₀ = 3 nM) that is selective for FGFR4 over other FGFR family members (IC₅₀s = 591, 493, and 150 nM for FGFR1, 2, and 3, respectively) and an extensive panel of additional kinases (selectivity score for BLU-9931 at 3 µM is 0.005). It inhibits proliferation of HCC cell lines with an activated FGFR4 signaling pathway (EC₅₀s = 0.02-0.11 µM) and demonstrates antitumor activity when administered orally at 100 mg/kg to mice bearing HCC xenografts that overexpresses FGF19 due to amplification or to mice bearing liver tumor xenografts that overexpresses FGF19 mRNA but lack FGF19 amplification.
