Mechanism of Action

Targets/IC₅₀/Ki	EGFR (L858R/T790M) ^[1] (Cell-free assay) 21.5 nM(Ki) EGFR (wt) ^[1] (Cell-free assay) 303.3 nM(Ki)
In vitro	Rociletinib (CO-1686) inhibits p-EGFR with IC50 ranging from 62 to 187 nM in mutant EGFR–expressing cells, while it inhibits EGFR phosphorylation with IC50 of > 2,000 nM in the three WT EGFR–expressing cells. This compound selectively inhibits growth of NSCLC cells expressing mutant EGFR with GI50 ranging from 7 to 32 nM, and induces apoptosis. CO-1686–resistant NSCLC cell lines exhibit signs of epithelial-mesenchymal transition and increased sensitivity to AKT inhibitors. ^[1]
Kinase Assay	Inhibition Kinetics Studies
Kinase Assay	Recombinant human wild-type and T790M/L858R double mutant EGFR, both N-terminal GST-tagged, are used in the assay for Rociletinib (CO-1686). The Omnia continuous read assay is performed as described by the vendor.
In vivo	Rociletinib (CO-1686) causes dose-dependent and significant tumor growth inhibition in all EGFR-mutant models as well as human EGFRL858R- and EGFRL858R/T790M-expressing transgenic mice. ^[1]
