Childhood Acute Myeloid Leukemia

This phase I trial tests the safety, side effects, best dose and effectiveness of revumenib in treating patients with acute leukemia after allogeneic stem cell transplant. Revumenib is in a class of medications called menin inhibitors. Revumenib targets and binds to the protein menin, thereby preventing the interaction between menin and the mixed lineage leukemia protein. Disrupting this interaction prevents the activation of specific genes that fuel the development of leukemia cells and inhibits the survival, growth, and production of certain kinds of leukemia cells. Giving revumenib may be safe, tolerable, and/or effective in treating patients with acute leukemia after allogeneic stem cell transplant.
