Comparing Standard Chemotherapy with CPX-351 and Gilteritinib for Children and Young Adults Newly Diagnosed with Acute Myeloid Leukemia With or Without FLT3 Mutations

What this Trial Is About

Researchers are evaluating a new treatment approach for children and young adults newly diagnosed with acute myeloid leukemia AML, including those with and without FLT3 gene mutations. The trial compares standard chemotherapy using daunorubicin, cytarabine, and gemtuzumab ozogamicin to therapy with CPX-351, a liposome-encapsulated form of daunorubicin and cytarabine, andor the drug gilteritinib which may block abnormal FLT3 gene function. The study aims to understand which treatment works better and to monitor heart function changes during and after therapy. Participants are assigned to different treatment groups based on their risk and FLT3 mutation status. Treatments include various chemotherapy regimens delivered intravenously and intrathecally, with some groups receiving CPX-351 and others receiving standard drugs. Patients with FLT3 mutations receive additional oral gilteritinib for extended periods, including maintenance therapy up to one year. Hematopoietic stem cell transplantation is also part of the treatment for some high-risk patients following chemotherapy courses. During the study, participants will undergo multiple assessments including blood tests, bone marrow biopsies, imaging scans, and neuropsychological testing to monitor leukemia status and treatment effects. Cardiac function is closely followed using echocardiography and biomarkers. Patient outcomes such as event-free survival, overall survival, minimal residual disease, relapse rates, and treatment safety are tracked for up to three years. The total study participation may extend over several years with ongoing evaluations.
