Description

BI-3406 is Potent & Selective SOS1::KRAS Inhibitor (IC50=5 nM), which Opens a New Approach for Treating KRAS-Driven Tumours. BI 3406 selectively binds to SOS1 and blocks the interaction with KRAS, irrespective of the KRAS mutation. BI 3406 causes RAS GTP and pERK reduction and inhibits cell growth of KRAS mutated cell lines, carrying most of the typical KRAS mutations (i.e. G12D, G12V, G13D and others). BI 3406, when administered orally to tumour bearing mice, causes a dose dependent tumour static effect that can be converted into regressions when combined with MEK1 inhibition

How to use

In Vitro:

BI-3406 is a highly potent and selective, orally bioavailable SOS1::KRAS inhibitor which binds to the catalytic domain of the guanine nucleotide exchange factor (GEF) SOS1 thereby preventing the interaction with KRAS-GDP. BI-3406 does not block the interaction of KRAS with SOS2 but elicits activity on a broad panel of KRAS oncogenic variants, including all major G12 and G13 oncoproteins. In KRAS-dependent cancers, BI-3406 potently reduces the formation of GTP-loaded KRAS, and inhibits MAPK pathway signaling. Down-modulation of this signaling cascade by BI-3406 in KRAS G12 or G13 mutant cells effectively limits cell proliferation.

In Vivo:

BI-3406 modulates signaling, as assessed by p-ERK and target genes, and displays marked anti-tumor efficacy in KRAS mutant xenografts. Due to BI-3406 blocking the negative feedback relief induced by MAPK inhibition, it has the potential to sensitize KRASdependent cancers to MEK inhibitor treatment. Combination with MEK inhibition leads to profound pathway blockade and tumor regressions in vivo.
