Biological Activity

PF-07284890 (ARRY-461) is an orally bioavailable, brain penetrant, potent, small molecule BRAF V600 mutants inhibitor, inhibits BRAF and CRAF with IC50 of 5.8 and 4.1 nM, respectively.
PF-07284890 inhibits the clinically relevant kinase domain BRAF V600 mutants (V600E and V600K) with IC50 of 24-25 nM.
PF-07284890 potently inhibits phosphorylation of ERK, a downstream marker of BRAF inhibition, and potently inhibits proliferation of BRAF V600E/K mutant melanoma cell lines (IC50=18-38 nM).
PF-07284890 inhibits phosphorylation of ERK in A375 BRAF V600E tumors, achieving maximal target inhibitions at a dose of 10 mg/kg.
PF-07284890 (10-30 mg/kg BID) caused significant and durable tumor regressions in the intracranial A375-luc BRAF V600E melanoma xenograft model.
