Description: M‑1121 is an Orally Active Covalent Inhibitor of Menin-MLL Interaction Capable of Achieving Complete and Long-Lasting Tumor Regression. M-1121 establishes covalent interactions with Cysteine 329 located in the MLL binding pocket of menin and potently inhibits growth of acute leukemia cell lines carrying MLL translocations with no activity in cell lines with wild-type MLL. Consistent with the mechanism of action, M-1121 drives dose-dependent down-regulation of HOXA9 and MEIS1 gene expression in the MLL-rearranged MV4;11 leukemia cell line. M-1121 is orally bioavailable and shows potent antitumor activity in vivo with tumor regressions observed at tolerated doses in the MV4;11 subcutaneous and disseminated models of MLL-rearranged leukemia.
