Therapy Description |
Idhifa (enasidenib) inhibits IDH2 to prevent 2HG formation, which may promote differentiation and inhibit proliferation of cancer cells (PMID: 28280273). Idhifa (enasidenib) is FDA-approved for use in patients with relapsed or refractory acute myeloid leukemia harboring an IDH2 mutation (R140Q/L/G/W, R172K/M/G/S/W) (FDA.gov). |
