Proliferation assays in KMT2A-r MOLM-13 AML cells showed that doublet combination of JNJ-75276617 plus venetoclax induced a synergistic antiproliferative effect in vitro that was significantly increased when compared to JNJ-75276617 or venetoclax monotherapy. The triplet combination of JNJ-75276617 plus azacitidine and venetoclax further induced a synergistic antiproliferative effect that was significantly increased when compared to JNJ-75276617 monotherapy or the doublet combination of venetoclax plus azacitidine....These studies suggest that the doublet combinations of either JNJ-75276617 plus venetoclax or azacitidine, or the triplet combination could potentially provide a beneficial treatment option for KMT2A- or NPM1-altered AML...
