menin-MLL (mixed-lineage leukemia) protein, interaction inhibitor, antineoplastic, DSP-5336, Fast Track, Orphan Drug designations
Enzomenib is an investigational new drug that is being evaluated for the treatment of acute leukemia.[1] It is a small molecule inhibitor that targets the interaction between menin and mixed-lineage leukemia (MLL) proteins.[2] Enzomenib particularly in patients with KMT2A (MLL) rearrangements or NPM1 mutations.[3]
The U.S. Food and Drug Administration (FDA) has granted both Fast Track and Orphan Drug designations to Enzomenib.[4]
Enzomenib is an orally bioavailable, small molecule inhibitor of menin, with potential antineoplastic activity. Upon oral administration, enzomenib targets and binds to the nuclear protein menin, thereby preventing the interaction between the two proteins menin and menin-mixed lineage leukemia (MLL; myeloid/lymphoid leukemia; KMT2A) and the formation of the menin-MLL complex. This reduces the expression of downstream target genes and results in an inhibition of the proliferation of MLL-rearranged leukemic cells. The menin-MLL complex plays a key role in the survival, growth, transformation and proliferation of certain kinds of leukemia cells.
