    Chromosomal translocations of the nucleoporin 98 (NUP98) gene are found in acute myeloid leukemia (AML) patients leading to very poor outcomes. The oncogenic activity of NUP98 fusion proteins is dependent on the interaction between Mixed Lineage Leukemia 1 and menin. NUP98-rearranged (NUP98-r) leukemia cells also rely on specific kinases, including CDK6 and/or FLT3, suggesting that simultaneous targeting of these kinases and menin could overcome limited sensitivity to single agents. Here, we found that combinations of menin inhibitor, MI-3454, with kinase inhibitors targeting either CDK6 (Palbociclib) or FLT3 (Gilteritinib) strongly enhance the anti-leukemic effect of menin inhibition in NUP98-r leukemia models. We found strong synergistic effects of both combinations on cell growth, colony formation and differentiation in patient samples with NUP98 translocations. These combinations also markedly augmented anti-leukemic efficacy of menin inhibitor in Patient Derived Xenograft models of NUP98-r leukemia. Despite inhibiting two unrelated kinases, when Palbociclib or Gilteritinib were combined with the menin inhibitor, they affected similar pathways relevant to leukemogenesis, including cell cycle regulation, cell proliferation and differentiation. This study provides strong rationale for clinical translation of the combination of menin and kinase inhibitors as novel treatments for NUP98-r leukemia, supporting the unexplored combinations of epigenetic drugs with kinase inhibitors.
