Rociletinib (CO-1686) is an orally delivered kinase inhibitor that specifically targets the mutant forms of EGFR including T790M, and the K_i values for EGFRL858R/T790M and EGFRWT are 21.5 nM and 303.3 nM, respectively.

Rociletinib (CO-1686) (0.1 μM) inhibits EGFR potently and irreversibly, and inhibits more than 50% of 23 targets. Rociletinib potently and selectively inhibits growth of NSCLC cells expressing mutant EGFR and induces apoptosis. Rociletinib resistant NSCLC cell lines are sensitive to AKT inhibition^[1].

Rociletinib (CO-1686) (100 mg/kg/day, p.o.) demonstrates anti-tumor activity in NSCLC EGFR mutant xenograft models. Rociletinib (CO-1686) (50 mg/kg bid, p.o.) demonstrates anti-tumor activity in human EGFR-L858R and EGFR-L858R-T790M expressing transgenic mice^[1].

Cells are seeded at 3,000 cells/well in growth media supplemented with 5% FBS, 2 mM L-glutamine, and 1 % P/S, allowed to adhere overnight, and treated with a dilution series of test compound (Rociletinib) for 72 hr. Cell viability is determined by CellTiter Glo and results are represented as background-subtracted relative light units normalized to a DMSO-treated control. Growth inhibition (GI₅₀) values are determined by GraphPad Prism 5.04. Combination index (CI) data is generated using CalcuSyn.

Briefly, NCr nu/nu mice are sub-cutaneously implanted with 1×10⁷ tumor cells in 50% Matrigel (injection volume of 0.2 mL/mouse). Once tumors reached 100-200 mm³, Animals are dosed with compounds (Rociletinib) as outlined (N=10 animals/gp). Briefly, LUM1686 PDX tumor fragments, harvested from donor mice, are inoculated into BALB/c nude mice. Administration of test compounds (Rociletinib (CO-1686)) is initiated at a mean tumor size of approximately 160 mm³. Tumor growth is monitored over time to determine tumor growth inhibition of the experimental agent vs. vehicle. The endpoint of the experiment is a mean tumor volume (MTV) in control group of 2000 mm³. Percent TGI is defined as the difference between the MTV of the designated control group and the MTV of the drug-treated group, expressed as a percentage of the MTV of the designated control group. Data is presented as mean±standard error of the mean (SEM).
