Ivosidenib is an orally available small molecule inhibitor of mutated isocitrate dehydrogenase-1 that is used as an antineoplastic agent in the treatment of adults of acute myelogenous leukemia (AML). Ivosidenib is associated with a moderate rate of serum aminotransferase elevations during therapy and is suspected to be the cause of rare instances of clinically apparent acute liver injury.
