Specification
Description
BI-847325 is an orally available dual inhibitor of mitogen-activated protein kinase kinase (MEK) and Aurora kinases, with potential antineoplastic activity. Upon oral administration, MEK/Aurora kinase inhibitor BI 847325 selectively binds to and inhibits the activity of MEK, which both prevents the activation of MEK-dependent effector proteins and inhibits growth factor-mediated cell signaling. BI 847325 also binds to and inhibits the activity of the Aurora kinases A, B and C which may disrupt the assembly of the mitotic spindle apparatus, prevent chromosome segregation, and inhibit both cellular division and proliferation in Aurora kinase-overexpressing tumor cells.

In Vitro Activity
The effects of BI 847325 in a cellular environment were investigated in a BRAFV600E-mutant melanoma cell line (A375) and a KRASQ61K-mutant NSCLC cell line (Calu-6). Proliferation was inhibited in both cell lines with GI50 values of 7.5 and 60 nmol/L, respectively. Western blot analysis indicated that in A375 cells, BI 847325 potently reduced the concentration of phospho-ERK, an indicator of MAPK pathway activity (partial to complete inhibition at 10-30 nmol/L), whereas about 10-fold higher concentrations were required in Calu-6 cells (Fig. 2A).

In Vivo Activity
BI 847325 induced gradual regression of A375 tumors in a mouse xenograft model that was sustained for the entire 4-week treatment period (Fig. 5A). In the Calu-6 model, sustained tumor stasis was observed upon treatment with BI 847325. Treatment with BI 847325 resulted in a profound decrease of phospho-HH3-positive cells in both models, whereas reduction in phospho-ERK was observed only in BRAF-mutant A375 xenografts.
