A Study to Find the Highest Dose of Cedazuridine and Decitabine Combination With Filgrastim as a Treatment Option After Hematopoietic Stem Cell Transplant in Children With High-Risk Acute Myeloid Leukemia

This phase I trial tests the safety, side effects, and best dose of ASTX727 and filgrastim for the treatment of children with high risk acute myeloid leukemia that has come back after a period of improvement (recurrent) or that does not respond to treatment (refractory) who have undergone allogenic hematopoietic stem cell transplantation. ASTX727 is a combination of cedazuridine and decitabine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine when taken by mouth, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Filgrastim works in synergy with decitabine and enhances its activity. Giving ATSX727 and filgrastim may be safe and tolerable in treating children with high risk, recurrent or refractory acute myeloid leukemia who have undergone allogenic hematopoietic stem cell transplantation.
