Mechanism of Action

Targets/IC₅₀/Ki	IDH1 ^[1] IDH2 ^[1]
In vitro	Vorasidenib (AG-881) is a pan-IDH1/2 inhibitor that selectively inhibits mutant IDH protein and induces cell differentiation in in vitro and in vivo models^[1]. Upon administration, this compound specifically inhibits mutant forms of IDH1 and IDH2, thereby inhibiting the formation of the oncometabolite 2-hydroxyglutarate (2HG) from alpha-ketoglutarate (a-KG). This prevents 2HG-mediated signaling and leads to both an induction of cellular differentiation and an inhibition of cellular proliferation in tumor cells expressing IDH mutations^[2].
In vivo	Vorasidenib (AG-881), which fully penetrates the blood-brain barrier, has been developed and is in early phase I testing for patients with IDH mutation-positive hematologic malignancies and solid tumors, including glioma^[3].
