Dual mTORC1/2 inhibition synergistically enhances AML cell death in combination with the BCL2 antagonist venetoclax.

The venetoclax/INK128 regimen exerts significant anti-leukemic activity in various preclinical models through mechanisms involving MCL-1 down-regulation and BAK/BAX activation, and offers potential advantages over PI3K or AKT inhibitors in cells with constitutive AKT activation. This regimen is active against primary and venetoclax resistant AML cells, and in in vivoAML models. Further investigation of this strategy appears warranted.
