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]

Names

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
