Ivosidenib (Tibsovo)
Revision as of 00:37, 3 May 2019 by Jwarner (talk | contribs) (→History of changes in FDA indication)
Mechanism of action
From the NCI Drug Dictionary: An orally available inhibitor of isocitrate dehydrogenase type 1 (IDH1), with potential antineoplastic activity. Upon administration, ivosidenib specifically inhibits a mutated form of IDH1 in the cytoplasm, which inhibits the formation of the oncometabolite, 2-hydroxyglutarate (2HG). This may lead to both an induction of cellular differentiation and an inhibition of cellular proliferation in IDH1-expressing tumor cells.
