What are the uses of this medicine?[edit | edit source]
- Olutasidenib (Rezlidhia) is a prescription medicine used to treat adults with acute myeloid leukemia (AML) with an isocitrate dehydrogenase-1 (IDH1) mutation when the disease has come back or has not improved after previous treatment(s).
How does this medicine work?[edit | edit source]
- An orally available inhibitor of 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.
