Olutasidenib

Olutasidenib (FT-2102) is a selective and potent isocitrate dehydrogenase-1 (IDH1) inhibitor approved by the FDA in December 2022. 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. 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. Olutasidenib inhibits the mutated IDH1 specifically, and provides a therapeutic benefit in IDH1-mutated cancers. Other IDH1 inhibitors, such as [ivosidenib], have also been approved for the treatment of relapsed or refractory AML. 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).
