What this Trial Is About

Researchers are evaluating the combination of gilteritinib with ivosidenib or enasidenib as a potential treatment for adults with relapsed or refractory acute myeloid leukemia (AML) who have specific gene mutations in FLT3 and IDH1 or IDH2. This Phase 1b study aims to find the highest dose of these drug combinations that causes only mild or manageable side effects and to assess their safety and effectiveness. Participants are divided into two groups: one group receives gilteritinib combined with ivosidenib, and the other receives gilteritinib combined with enasidenib. Both combinations are taken daily in continuous 28-day cycles at assigned dose levels, with different doses tested to find the maximum tolerated dose. The study is non-randomized and open-label, meaning participants and researchers know which treatments are given. During the study, participants will be monitored for side effects and toxicities for up to one year while researchers determine the safest dose. Clinical responses to the treatment will also be evaluated during this period. Participants will undergo regular assessments including blood tests and mutation analysis to track their health and treatment effects. The study is sponsored by Memorial Sloan Kettering Cancer Center and participation lasts as long as needed to evaluate safety and response.
