Description
Quizartinib (AC220) is a second-generation inhibitor for with of 1.1 nM/4.2 nM in MV4-11 and RS4;11 cells, respectively, 10-fold more selective for Flt3 than KIT, PDGFRα, PDGFRβ, RET, and CSF-1R. Quizartinib (AC220) induces of tumor cells. Phase 3.
Features
The most potent cellular FLT3-ITD inhibitor.
In vitro
AC220, a unique, potent and selective inhibitor of FLT3, has high affinity for FLT3 with a K value of 1.6 nM. AC220 inhibits the autophosphorylation of FLT3 in the human leukemia cell lines MV4-11 which harbor a homozygous FLT3-ITD mutation and is FLT3 dependent, and RS4;11 which expresses wild-type FLT3 with IC50 values of 1.1 nM and 4.2 nM, respectively. AC220 is the most potent cellular FLT3-ITD inhibitor, leading to the most significant inhibition of MV4-11 cell proliferation with IC50 of 0.56 nM compared to all other FLT3 inhibitors whose IC50 values range from 0.87 nM to 64 nM. AC220 has no inhibitory activity against the proliferation of A375 cells which harbor an activating mutation in BRAF and are not FLT3 dependent, indicating a large window between FLT3 inhibition and general cytotoxic effects.
In vivo
Oral administration of AC220 (10 mg/kg) induces time-dependent inhibition of FLT3 autophosphorylation in the FLT3-ITD–dependent MV4-11 tumor xenograft mouse model; the inhibition being 90% at 2 hours and 40% at 24 hours. AC220 significantly extends survival in a mouse model of FLT3-ITD AML with doses as low as 1 mg/kg given orally once a day. Treatment with AC220 at 10 mg/kg for 28 days results in rapid and complete regression of tumors in all mice with no tumor regrowth during the 60-day posttreatment period. AC220 displays more significant efficacy compared to sunitinib treatment which causes tumors to shrink slowly and resume growth immediately upon discontinuation of treatment in all but one of the mice.
