Description: BLU9931 is a potent and irreversible small-molecule inhibitor of FGFR4, as a targeted therapy to treat patients with HCC whose tumors have an activated FGFR4 signaling pathway. BLU9931 is exquisitely selective for FGFR4 versus other FGFR family members and all other kinases. BLU9931 shows remarkable antitumor activity in mice bearing an HCC tumor xenograft that overexpresses FGF19 due to amplification as well as a liver tumor xenograft that overexpresses FGF19 mRNA but lacks FGF19 amplification. Approximately one third of patients with HCC whose tumors express FGF19 together with FGFR4 and its coreceptor klotho β (KLB) could potentially respond to treatment with an FGFR4 inhibitor.

Biological target: BLU9931 is an irreversible fibroblast growth factor receptor 4 (FGFR4) inhibitor with an IC50 of 3 nM and a Kd of 6 nM.
In vitro activity: PK-1 cells exhibited a dose-dependent decrease in proliferation in the presence of BLU9931 (Figure 3A). An inhibitory effect on proliferation was also observed in T3M-4 cells (Figure S3A). By contrast, BLU9931 did no inhibit proliferation in PK-45P cells (Figure 3A), which expressed very low FGFR4 levels (Figure 1). Next, this study examined whether BLU9931 exerts toxic effects in PDAC cells. Incubation of PK-1 cells with 2 μM BLU9931 followed by fluorescence activated cell sorter (FACS) analysis using annexin V and propidium iodide (PI) showed that ~2% of the cells underwent apoptosis, necrosis, or cell injury (Figure 3B). Higher concentration (>10 μM) of BLU9931 revealed dead and floating cells suggestive of a toxic effect at these very high concentrations of the drug.

In vivo activity: Mice with YTN16 s.c. transplanted or peritoneally transplanted mice were treated for 3 weeks with BLU9931, a potent, selective, and irreversible FGFR4 inhibitor. Growth of s.c. tumor in BLU9931‐treated mice was slightly blunted compared to non‐treated mice (Figure 7A,B). However, the growth of peritoneal dissemination was remarkably different. Only very small spots of peritoneal dissemination were detected macroscopically and microscopically in BLU9931‐treated mice (Figure 7C,D,E,G). Surprisingly, the histology of s.c. tumor after BLU9931 treatment was remarkably different from that of the original tumor, even though the difference in growth rate was small (Figure 7F,H). YTN16 tumor formed glands, whereas BLU9931‐treated YTN16 tumor formed few glands in all 3 transplanted mice. After activation of FGFR, signaling of Stat3, Erk, and Akt is known to be activated downstream. Staining for all 3 markers was weaker in BLU9931‐treated tumor compared to the original YTN16 tumor.
