MRX-2843 is a potent and orally active inhibitor of MERTK and FLT3 with IC50 values of 1.3 nM and 0.64 nM, respectively. MRX-2843 induces apoptosis and inhibits colony formation in AML cell lines. In MOLM-14 cells, treatment with MRX-2843 inhibits phosphorylation of FLT3 and downstream signaling through STAT5, ERK1/2 and AKT.
In vivo, MRX-2843 is 78% orally bioavailable at a dose of 3 mg/kg with a Cmax of 1.3 μM and a t1/2 of 4.4 hours. In MOLM-14 parental xenografts, both quizartinib and MRX-2843 increase median survival compare with that of vehicle-treated mice (172.5 days versus 40 days and 121 days versus 36 days, respectively, P<0.001).
