Ivosidenib

Ivosidenib is an orally available inhibitor of isocitrate dehydrogenase type 1 (IDH1), with potential antineoplastic activity. Ivosidenib specifically inhibits a mutated form of IDH1 in the cytoplasm, which inhibits the formation of the oncometabolite, 2-hydroxyglutarate (2 hG). This may lead to both an induction of cellular differentiation and an inhibition of cellular proliferation in IDH1-expressing tumor cells.

TF-1 cells or primary human AML patient samples expressing mutant IDH1 are treated with AG-120.Treatment with AG-120 decreases intracellular 2-HG levels, inhibites growth factor independent proliferation and restores erythropoietin (EPO)-induced differentiation in TF-1 IDH1-R132H cells. Similarly, pharmacological inhibition of mutant IDH1 enzyme with AG-120 in primary human blast cells cultured ex vivo provides an effective way to lower intracellular 2-HG levels and induces myeloid differentiation[1].
