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 (2HG).
In vitro, 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.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
