SNDX-5613 and Gilteritinib for the Treatment of Relapsed or Refractory FLT3-Mutated Acute Myeloid Leukemia and Concurrent MLL-Rearrangement or NPM1 Mutation

Study Summary

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.

Primary Outcome

Adverse events will be graded according to Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. The toxicity data captured will include type, frequency, grade, severity, timing of onset, duration and relationship to study drug. Frequency tables will be used to summarize the AE data, where the number of patients with different types of AE will be tabulated by toxicity grade, counting only the highest grade of a certain type of AE occurred to the same patient.
