Mechanism of action

BION-1301 binds to FGFR4, a receptor overexpressed in hepatocellular carcinoma, blocking FGF19-FGFR4 signaling that drives tumor proliferation and survival. By inhibiting this pathway, the drug aims to slow or stop cancer cell growth. This approach is particularly relevant in HCC where FGF19-FGFR4 axis activation is a common oncogenic driver.
