Acute Myeloid Leukemia With NPM1 Mutation

This phase Ib trial tests the safety, side effects, and best dose of SNDX-5613 when given in combination with the standard chemotherapy treatment (daunorubicin and cytarabine) in treating patients with newly diagnosed acute myeloid leukemia that has changes in the NPM1 gene or MLL/KMT2A gene. SNDX-5613 blocks signals passed from one molecule to another inside cancer cells that are needed for cancer cell survival. Drugs used in chemotherapy, such as daunorubicin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding SNDX-5613 to the standard chemotherapy treatment may be able to shrink or stabilize the cancer for longer than the standard chemotherapy treatment alone.

This phase I trial tests the safety, side effects, and best dose of SNDX-5613 and gilteritinib for treating patients with acute myeloid leukemia that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory) and has a mutation in the FLT3 gene along with either a mutation in the NMP1 gene or a type of mutation called a rearrangement in the MLL gene. SNDX-5613 is in a class of medications called menin inhibitors. It works by blocking the action of mutated MLL and NMP1 proteins that signal cancer cells to multiply. Gilteritinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of mutated FLT3 proteins that signal cancer cells to multiply. Giving SNDX-5613 with gilteritinib may be safe, tolerable and/or effective in treating patients with relapsed/refractory FLT3 mutated acute myeloid leukemia.
