SYN Caravella JA, et al. Structure-Based Design and Identification of FT-2102 (Olutasidenib), a Potent Mutant-Selective IDH1 Inhibitor. J Med Chem. 2020 Feb 27;63(4):1612-1623. doi: 10.1021/acs.jmedchem.9b01423. Epub 2020 Feb 12.

FDA 12/1/2022, To treat adults with relapsed or refractory acute myeloid leukemia with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation, Rezlidhia

Olutasidenib, sold under the brand name Rezlidhia, is an anticancer medication used to treat relapsed or refractory acute myeloid leukemia.[1][2] Olutasidenib is an isocitrate dehydrogenase-1 (IDH1) inhibitor.[1] It is taken by mouth.[1]

Olutasidenib was approved for medical use in the United States in December 2022.[1][2][3][4]

Medical uses

Olutasidenib is indicated for the treatment of adults with relapsed or refractory acute myeloid leukemia with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test.[1][2]

Society and culture


Olutasidenib is the international nonproprietary name.[5]

Olutasidenib is an isocitrate dehydrogenase-1 (IDH1) inhibitor indicated for the treatment of patients with relapsed or refractory acute myeloid leukemia with a susceptible IDH1 mutation as detected by an FDA-approved test.

Olutasidenib (FT-2102) is a selective and potent isocitrate dehydrogenase-1 (IDH1) inhibitor approved by the FDA in December 2022.5,6 It is indicated for the treatment of relapsed or refractory acute myeloid leukemia (AML) in patients with a susceptible IDH1 mutation as determined by an FDA-approved test.5 IDH1 mutations are common in different types of cancer, such as gliomas, AML, intrahepatic cholangiocarcinoma, chondrosarcoma, and myelodysplastic syndromes (MDS), and they lead to an increase in 2-hydroxyglutarate (2-HG), a metabolite that participates in tumerogenesis.1,2 Olutasidenib inhibits the mutated IDH1 specifically, and provides a therapeutic benefit in IDH1-mutated cancers.1,5

Other IDH1 inhibitors, such as ivosidenib, have also been approved for the treatment of relapsed or refractory AML.3,4 Olutasidenib is orally bioavailable and capable of penetrating the blood-brain barrier, and is also being evaluated for the treatment of myelodysplastic syndrome (MDS), as well as solid tumors and gliomas (NCT03684811).4
