- Event-free survival (EFS) [ Time Frame: Up to 3 years ]The Kaplan-Meier method will be used to estimate 3-year EFS, defined as the time from study entry until induction failure, relapse, secondary malignancy, or death.
- Overall survival (OS) [ Time Frame: Up to 3 years ]The Kaplan-Meier method will be used to estimate 3-year OS, defined as the time from study entry until death.
- Proportion of patients positive for minimal residual disease (MRD+) [ Time Frame: Up to 4 weeks ]The proportion of patients MRD+ at end of induction 1 (EOI1) will be estimated as the number of patients MRD+ divided by the number of patients with evaluable EOI1 MRD results along with a corresponding 95% confidence interval determined using a binomial exact method.
- Proportion of patients who died during protocol therapy [ Time Frame: Up to 2 years ]The proportion of patients who died during protocol therapy will be estimated along with the corresponding 95% confidence interval determined using a binomial exact method.
- Relapse rate [ Time Frame: Up to 3 years ]Cumulative incidence estimates will be used to determine the 3 year relapse rate defined as time from study entry to induction failure or relapse where deaths or secondary malignancies are competing events.
- Treatment-related mortality rate (TRM) [ Time Frame: Up to 3 years ]Cumulative incidence estimates will be used to determine the 3 year TRM defined as time from study entry to death where induction failure, relapse or secondary malignancies are competing events.
- Incidence of adverse events [ Time Frame: Up to 2 years ]The proportion of patients experiencing at least one grade 3 or higher non-hematologic toxicity and infection while on protocol therapy will be estimated along with the corresponding 95% confidence interval determined using a binomial exact method. Toxicity will be assessed by Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0).
- Course duration [ Time Frame: Up to 2 years ]Median and range of the length of course duration will be determined.
- Length of hospitalization [ Time Frame: Up to 2 years ]Median and range of the length of hospitalization time during protocol therapy will be determined.
- Time to count recovery [ Time Frame: Up to 2 years ]Cumulative incidence estimates that account for competing events will be used to estimate time to count recovery in days where deaths are competing events.

-
Patient must have 1 of the following:
-
>= 20% bone marrow blasts (obtained within 14 days prior to enrollment)
- In cases where extensive fibrosis may result in a dry tap, blast count can be obtained from touch imprints or estimated from an adequate bone marrow core biopsy
- < 20% bone marrow blasts with one or more of the genetic abnormalities associated with childhood/young adult AML as provided in the protocol (sample obtained within 14 days prior to enrollment)
- A complete blood count (CBC) documenting the presence of at least 1,000/uL (i.e., a white blood cell [WBC] count >= 10,000/uL with >= 10% blasts or a WBC count of >= 5,000/uL with >= 20% blasts) circulating leukemic cells (blasts) if a bone marrow aspirate or biopsy cannot be performed (performed within 7 days prior to enrollment)
-
-

- ARM C: Patient must have FLT3/ITD allelic ratio > 0.1 as reported by Molecular Oncology
- ARM C: Patient does not have any congenital long QT syndrome or congenital heart block
- ARM C: Females of reproductive potential must agree to use effective contraception during treatment and for at least 6 months after the last dose of gilteritinib
- ARM C: Lactating women must agree not to breastfeed during treatment with gilteritinib and for 2 months after the last dose of gilteritinib
- ARM C: Males of reproductive potential must agree to use effective contraception during treatment and for at least 4 months after the last dose of gilteritinib

- ARM D: Males of reproductive potential must agree to use effective contraception during treatment and for at least 4 months after the last dose of gilteritinib
- NEUROPSYCHOLOGICAL TESTING: Patient must be enrolled on Arm A or Arm B. Patients who transfer to Arm C or Arm D are not eligible
- NEUROPSYCHOLOGICAL TESTING: Patient must be 5 years or older at the time of enrollment
- NEUROPSYCHOLOGICAL TESTING: English-, French- or Spanish-speaking
- NEUROPSYCHOLOGICAL TESTING: No known history of neurodevelopmental disorder prior to diagnosis of AML (e.g., Down syndrome, fragile X, William syndrome, mental retardation)
- NEUROPSYCHOLOGICAL TESTING: No significant visual or motor impairment that would prevent computer use or recognition of visual test stimuli
- All patients and/or their parents or legal guardians must sign a written informed consent
- All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met.
Exclusion Criteria:
- Fanconi anemia
- Shwachman Diamond syndrome

- Patients with persistent cardiac dysfunction prior to enrollment, defined as ejection fraction (EF) < 50% (preferred method Biplane Simpson's EF) or if EF unavailable, shortening fraction (SF) < 24%. *Note: if clinically safe and feasible, repeat echocardiogram is strongly advised in order to confirm cardiac dysfunction following clinical stabilization, particularly if occurring in the setting of sepsis or other transient physiologic stressor. If the repeat echocardiogram demonstrates an EF >= 50%, the patient is eligible to enroll and may receive an anthracycline-containing Induction regimen
-
Administration of prior anti-cancer therapy except as outlined below:

Patients receiving gilteritinib will be required to avoid strong CYP3A4 inducers and/or strong P-gp inducers for the duration of the study treatment
