A novel Menin-MLL inhibitor induces specific chromatin changes and eradicates disease in models of MLL-rearranged leukemia

Project description:Inhibition of the Menin (encoded by MEN1) and MLL1 (KMT2A) protein-protein interaction has been proposed as a potential targeted therapeutic strategy for MLL-rearranged (MLL-r) leukemia. We sought to develop more potent and selective Menin-MLL1 interaction inhibitors that are effective in vitro and in vivo to directly assess potential therapeutic opportunities. Structure-based design yielded the potent, highly selective and orally-bioavailable small molecule inhibitor VTP-50469. Human cell lines carrying MLL-rearrangements were highly sensitive and selectively responsive to treatment with VTP-50469. VTP-50469 displaced Menin from high molecular weight protein complexes and inhibited chromatin occupancy of MLL1 at select target genes. Loss of MLL1 binding led to specific changes in gene expression, cellular differentiation, and apoptosis. Mice engrafted with leukemia cells isolated from patients with either MLL-r AML or MLL-r ALL showed dramatic reductions of leukemia burden and prolonged survival when treated with VTP-50469. Remarkably, multiple mice engrafted with MLL-r ALL remained disease free greater than 1 year following cessation of treatment. Therefore, inhibition of the Menin-MLL1 interaction with VTP-50469 is highly effective in patient-derived xenograft (PDX) models of human MLL-r AML and MLL-r ALL which supports rapid translation of this approach to clinical trials. This submission represents the scRNAseq component of the study.

A novel Menin-MLL inhibitor induces specific chromatin changes and eradicates disease in models of MLL-rearranged leukemia [ChIP-seq]

Project description:Treatment of cells carrying MLL-rearrangements with VTP-50469 (specific Menin-MLL1 inhibitor) displaces Menin from high molecular weight complexes and chromatin genome-wide. Since VTP-50469 block Menin interaction with MLL1 we tested using chip-seq if treatment with VTP-50469 also displaces MLL1 or MLL-fusions from chromatin. We found that the VTP-50469 treatment displaced MLL-fusions from only a subset of MLL-fusion binding sites. Since DOT1L is associated with MLL-AF9 we then tested if displacement of MLL1 also leads to loss of DOT1L association with chromatin on MLL-AF9 binding sites. We found that DOT1L binds to thousands of genes, treatment with VTP-50469 leads to genome wide loss of DOT1L binding including the same subset of MLL-fusion binding sites.

A novel Menin-MLL inhibitor induces specific chromatin changes and eradicates disease in models of MLL-rearranged leukemia [RNA-seq]

Project description:Cells carrying MLL-rearrangements are sensitive to treatment with VTP-50469 with IC50 in 20-60 nM. We treated MOLM13 or RS4;11 cells with DMSO (0.33%) or VTP-50469 (100-330nM), followed by digital gene expression analyses of 3'end RNA-seq data. We found that very few genes significantly change expression >2-fold after 2 days of treatment, while after 7-day treatment more genes significantly changed expression >2-fold. The genes that lost expression after VTP-50469 treatment were enriched in MLL-fusion target genes and DOT1L-sensitive genes. Moreover, treatment with both EPZ-5676 and VTP-50469 suppress similar subsets of genes, however VTP-50469 suppress genes faster as compared to EPZ-5676. Treatment of PDX with VTP-50469 suppressed similar gene sets, namely MLL-fusion targets and DOT1L-sensitive genes.

Gene expression induced by DOT1L and Menin inhibition in cell line models of leukemia

Project description:Gene expression upon DOT1L inhibition, or Menin inhibition, or a combination of DOT1L and Menin inhibiting agents, was assessed in several MLL-rearranged human cell lines and a mouse model of MLL-AF9 leukemia. The goal of the study was to explore the mechanisms by which the EPZ0004777 and MI-2-2 chemicals collaborate to induce differentiation and cell death in MLL-AF4 and MLL-AF9 leukemias.
