Daiichi Sankyo Company, Limited (hereafter Daiichi Sankyo) today announced the first patient has been dosed in the first-in-human phase 1/2 study of DS-1594, a selective small-molecule menin inhibitor, in adults with relapsed/refractory acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). The trial is being conducted by The University of Texas MD Anderson Cancer Center under an existing strategic research collaboration.
Inhibition of the menin protein is being studied as a novel treatment approach for acute leukemias with MLL rearrangement (MLLr) or NPM1 mutation (NPM1m), two gene alterations that drive cancer development and growth.
1 MLLr occurs in approximately 5 to 10% of acute leukemia patients and is associated with aggressive disease, reduced treatment response and poor prognosis.
