UP TO 50% OF AML PATIENTS MAY BENEFIT FROM MENIN INHIBITOR THERAPY

22,010 new cases of AML diagnosed in the

U.S. each year1

AML is characterized by significant genetic heterogeneity due to driver mutations, including NPM1-m, FLT3-m, IDH1/2-m and KMT2A-r2,3

NPM1 mutations are observed in 30% to 35% of cases and are an important upstream driver mutation that uses the menin pathway4,5
