How to use

In Vitro:

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

In Vivo:

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