How to use

In Vitro:

JBJ-04-125-02 can inhibit cell proliferation in vitro. Osimertinib, an ATP-competitive covalent EGFR inhibitor, uniquely and significantly enhances the binding of JBJ-04-125-02 for mutant EGFR. The combination of osimertinib and JBJ-04-125-02 results in an increase in apoptosis, a more effective inhibition of cellular growth in vitro compared to either single agent alone.

In Vivo:

JBJ-04-125-02 can inhibit EGFR L858R/T790M/C797S signaling in vivo. The combination of osimertinib and JBJ-04-125-02 results in an increase in apoptosis, and an increased efficacy in vivo compared to either single agent alone.
