A Phase 3 Randomized Trial for Patients With De Novo AML Comparing Standard Therapy Including Gemtuzumab Ozogamicin (GO) to CPX-351 With GO, and the Addition of the FLT3 Inhibitor Gilteritinib for Patients With FLT3 Mutations
Children's Oncology Group
Summary
This phase III trial compares standard chemotherapy to therapy with liposome-encapsulated daunorubicin-cytarabine (CPX-351) and/or gilteritinib for patients with newly diagnosed acute myeloid leukemia with or without FLT3 mutations. Drugs used in chemotherapy, such as daunorubicin, cytarabine, and gemtuzumab ozogamicin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. CPX-351 is made up of daunorubicin and cytarabine and is made in a way that makes the drugs stay in the bone marrow longer and could be less likely to cause heart problems than traditional anthracycline drugs, a common class of chemotherapy drug. Some acute myeloid leukemia patients have an abnormality in the structure of a gene called FLT3. Genes are pieces of DNA (molecules that carry instructions for development, functioning, growth and reproduction) inside each cell that tell the cell what to do and when to grow and divide. FLT3 plays an important role in the normal making of blood cells. This gene can have permanent changes that cause it to function abnormally by making cancer cells grow. Gilteritinib may block the abnormal function of the FLT3 gene that makes cancer cells grow. The overall goals of this study are, 1) to compare the effects, good and/or bad, of CPX-351 with daunorubicin and cytarabine on people with newly diagnosed AML to find out which is better, 2) to study the effects, good and/or bad, of adding gilteritinib to AML therapy for patients with high amounts of FLT3/ITD or other FLT3 mutations and 3) to study changes in heart function during and after treatment for AML. Giving CPX-351 and/or gilteritinib with standard chemotherapy may work better in treating patients with acute myeloid leukemia compared to standard chemotherapy alone.
Description
PRIMARY OBJECTIVE: I. To compare event-free survival (EFS) in children with de novo acute myeloid leukemia (AML) without FLT3 mutations who are randomly assigned to standard induction therapy on Arm A with daunorubicin, cytarabine (DA) and gemtuzumab ozogamicin (GO) (DA-GO) versus Arm B with CPX-351 and GO. SECONDARY OBJECTIVES: I. To compare overall survival (OS) and rates of end of Induction 1 (EOI1) minimal residual disease (MRD) in children with de novo AML without FLT3 mutations who are randomly assigned to standard induction therapy (Arm A) with DA-GO versus CPX-351 and GO (Arm B).
