What this Trial Is About

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.
