in vitro study | BI-847325 showed growth inhibition on BRAF mutant and vemurafenib resistant melanoma cells, with IC50 ranging from 0.3 nM-2 μM and preventing colony formation in 6 BRAF mutant melanoma cell lines. BI-847325 also induce apoptosis by reducing Mcl-1 expression. |
in vivo study | in mice loaded with 1205Lu and 1205LuR xenografts, BI-847325 (75 mg/kg, p.o.) caused significant tumor degeneration without significant weight change. |
