Summary

This phase III trial compares standard chemotherapy to therapy with 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 liposome-encapsulated daunorubicin-cytarabine (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).

II. To estimate the EFS and rate of EOI1 MRD in FLT3 internal tandem duplication mutation positive patients (FLT3/ITD+; as defined by allelic ratio > 0.1) without favorable cytomolecular characteristics (NPM1 and/or CEBPA) receiving gilteritinib fumarate (gilteritinib) in combination with DA-GO (Arm AC).

III. To estimate the EFS and rate of EOI1 MRD in patients with non-ITD FLT3 activating mutations who receive backbone therapy (DA-GO or CPX-351 and GO) with gilteritinib (Arms AD and BD).

IV. To determine the feasibility of combining gilteritinib and DA-GO or CPX-351 and GO in patients with FLT3/ITD mutations (Arm AC/Arm BC/Arm AD/Arm BD).

V. To compare EOI1 MRD and EFS in patients with FLT3/ITD AML+ (allelic ratio [AR] > 0.1) without favorable cytogenetic/molecular characteristics treated with DA-GO-gilteritinib versus (vs) CPX-GO-gilteritinib (Arm AC vs Arm BC).

VI. To compare the incidence of significant left ventricular systolic dysfunction (LVSD) 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).

VII. To compare the changes in echocardiography-derived measures of cardiac function, including left ventricular ejection fraction (EF) and global longitudinal strain (GLS), throughout AML therapy in patients with low and high risk AML without FLT3 mutations receiving Arm A vs Arm B.

VIII. Determine if early changes in sensitive echocardiographic measures of cardiac function (i.e., post-Induction 1 decline in GLS) and elevations in circulating cardiac biomarkers (i.e., cardiac troponin T and N-terminal pro b-type natriuretic peptide) are associated with subsequent declines in left ventricular ejection fraction in patients with non-FLT3 mutant AML receiving therapy on Arms A or B.

IX. To compare longitudinal acute changes in neuropsychological functioning and neurocognitive late effects between those with central nervous system (CNS) disease and those without CNS disease and between those treated with hematopoietic stem cell transplant (HSCT) and those treated with chemotherapy only for patients on Arms A and B.

X. To compare cardiotoxicity measures (EF, GLS, and cardiac biomarkers) in patients receiving standard induction with dexrazoxane hydrochloride (dexrazoxane) vs. CPX-351 in the context of gilteritinib therapy and explore whether the differential cardiotoxicity across arms varies from that observed in non-FLT3 mutant AML without gilteritinib exposure.

EXPLORATORY OBJECTIVES:

I. To estimate the EFS and rate of EOI1 MRD in patients with high allelic ratio (HAR) FLT3/ITD+ patients, as historically defined by an AR > 0.4, receiving gilteritinib in combination with DA-GO (Arm AC with AR > 0.4).

II. To estimate the EFS and rate of EOI1 MRD in FLT3/ITD+ patients (as defined by allelic ratio > 0.1) with NPM1 and/or bZIP CEBPA mutations receiving gilteritinib in combination with DA-GO (Arm AC).

III. Compare the changes in high sensitivity troponin and natriuretic peptide elevations throughout AML therapy, as measured at the end of each chemotherapy course, in patients with low and high risk AML without FLT3 mutations receiving Arm A vs Arm B.

IV. Quantify the association of host factors (age, sex, body mass index [BMI], race), treatment exposures (cumulative anthracycline dose, anthracycline arm, hematopoietic stem cell transplant vs. chemotherapy alone), early declines in GLS, and elevations in cardiac biomarkers (cTnT and NT-proBNP) with subsequent LVSD.

V. Develop a multi-marker risk prediction model incorporating significant host factors, treatment exposures, and echocardiographic predictors for the development of LVSD within 1 year of completing therapy.

VI. To describe the rates of CNS disease utilizing an updated strategy for diagnosing and defining CNS disease in pediatric AML.

VII. To describe the rates of CNS relapse (both isolated CNS and combined bone marrow/CNS) when utilizing this updated strategy as well as changing CNS prophylaxis and treatment to include triple intrathecal chemotherapy.

VIII. To describe disease-free survival (DFS) and overall survival (OS) in high risk patients based on multi-dimensional flow cytometry detection of measurable residual disease prior to hematopoietic stem cell transplant (HSCT).

IX. To describe plasma metabolomics that may impact efficacy, toxicity, and/or pharmacokinetics of allogeneic HSCT.

X. To estimate the prevalence of non-risk stratifying cytogenetic/molecular variants and assess their impact on outcome in childhood AML.
