In vitro | Cell lines carrying MLL-rearrangements are selectively responsive to VTP50469. VTP50469 displaces Menin from protein complexes and inhibits chromatin occupancy of MLL at select genes. Loss of MLL binding leads to changes in gene expression, differentiation, and apoptosis.[2] | ||
In vivo | Patient-derived xenograft (PDX) models derived from patients with either MLL-r AML or MLL-r ALL shows dramatic reductions of leukemia burden when treated with VTP50469. Multiple mice engrafted with MLL-r ALL remains disease free greater than one year after treatment.[2] |
