== '''What are the uses of this medicine?''' ==

* Olutasidenib ('''Rezlidhia''') is a prescription medicine used to treat adults with [[acute myeloid leukemia]] (AML) with an [[Isocitrate dehydrogenase-1 gene|isocitrate dehydrogenase-1]] (IDH1) mutation when the disease has come back or has not improved after previous treatment(s).

== '''How does this medicine work?''' ==

* An orally available '''inhibitor of [[Isocitrate dehydrogenase-1 gene|isocitrate dehydrogenase type 1]]''' (IDH1; IDH-1; IDH1 [NADP+] soluble) with a mutation at arginine (R) 132, IDH1(R132), with potential [[antineoplastic]] activity.
* Upon administration, olutasidenib specifically '''inhibits IDH1(R132), 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(R132).
* IDH1(R132) mutations are highly expressed in certain malignancies, including [[gliomas]]; they initiate and drive cancer growth by both blocking cell differentiation and catalyzing the formation of 2HG.
