Registration Criteria:
- Any patient undergoing bone marrow biopsy with suspicion of or known diagnosis of
acute myeloid leukemia (AML) will be asked to sign a Prescreening Consent to allow
for centralized testing of bone marrow/peripheral blood samples.
Randomization Eligibility Criteria:
- Patient must have previously untreated FLT3 mutated Non M3 AML (FLT3-TKD or FLT3-ITD
allowed).
° Standard of care induction 7+3 chemotherapy may start prior to randomization using
same regimen and doses as defined in the protocol while awaiting prescreening test
results.
- Patient must have had no prior systemic therapy for AML, except as noted below:
- Hydroxyurea and emergent leukapheresis or preemptive treatment with retinoic
acid prior to exclusion of Acute Promyelocytic Leukemia (APL) allowed.
- Prior therapy for myelodysplastic syndrome (MDS) or myeloproliferative
neoplasms (MPN) (e.g., thalidomide or lenalidomide, interferon, jakafi,
cytokines, 5-azacytidine or decitabine, histone deacetylase inhibitors).
- Initiation of standard of care 7+3 induction chemotherapy using same regimen
and doses as defined in protocol while awaiting prescreening test results
- Patient may not have received hypomethylating agent within 21 days.
- Patient may not have M3 AML.
- Patient may not have AML with known Core Binding Factor -t(8;21), inv(16), t(16;16).
- Patient may not have known active Central Nervous System (CNS) leukemia.
° Prophylaxis with intrathecal chemotherapy is allowed prior to or during
induction/consolidation.
- Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status of
0-3.
- Patient must be age ≥ 18 years to ≤ 70 years.
- Patient must be able to understand and willing to sign Institutional Review Board
(IRB)-approved informed consent.
- Patient must be willing to provide mandatory bone marrow and blood samples for
research.
- Patient must have adequate organ function as measured by the following criteria,
obtained ≤ 48 hours prior to randomization except ECG and left ventricular ejection
fraction (LVEF) which can be done ≤ 2 weeks prior to randomization:
- Serum creatinine ≤ 1.5x institutional upper limit of normal (ULN), or if serum
creatinine outside normal range, then glomerular filtration rate (GFR) >40
mL/min as measured by Cockcroft-Gault formula.
- Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) ≤ 3x ULN,
unless secondary to leukemia.
- Serum total or direct bilirubin <2 mg/dL, unless due to Gilbert's, hemolysis or
leukemic infiltration.
- Fridericia-Corrected QT Interval (QTcF) interval ≤ 500 msec (using Friderica's
correction).
- Left Ventricular Ejection Fraction >45%.
- The patient may not be known to have hypokalemia and/or hypomagnesemia that does not
respond to supplementation.
- A female patient is eligible to participate if she is not pregnant and at least one
of the following conditions apply:
- Not a woman of childbearing potential (WOCBP) OR
- WOCBP who agrees to follow the contraceptive guidance throughout the treatment
period and for at least 180 days after the final study drug administration.
- Female patient must agree not to breastfeed or donate ova starting at treatment and
throughout the study period, and for at least 180 days after the final study drug
administration.
- A male patient must agree not to donate sperm starting at treatment and throughout
the study period, and for at least 120 days after the final study drug
administration.
- A male patient with female partner(s) of child-bearing potential must agree to use
contraception during the treatment period, and for at least 120 days after the final
study drug administration.
- Male patient with a pregnant or breastfeeding partner(s) must agree to remain
abstinent or use a condom for the duration of the pregnancy or time partner is
breastfeeding throughout the treatment period, and for at least 120 days after the
final study drug administration.
- Patient may not have another malignancy that could interfere with the evaluation of
safety or efficacy of this combination.
- Patient may not have a history of Long QT Syndrome.
- Patient may not have evidence of uncontrolled angina, severe uncontrolled
ventricular arrhythmias, electrocardiographic evidence of acute ischemia, or
congestive heart failure (CHF) New York Heart Association (NYHA) Class 3 or 4.
Patient may also not have a history of CHF NYHA Class 3 or 4 in the past, unless a
prescreening echocardiogram (ECHO) or multigated acquisition scan (MUGA) performed
within 2 weeks prior to study entry with results of left ventricular ejection
fraction >45%.
- Patient may not have had major surgery or radiation therapy within 4 weeks of
registration.
- Patient may not require treatment with concomitant drugs that are strong inducers of
CYP3A and P-gp.
- Patient with a known allergy to any of the study medications, their analogues, or
excipients in the various formulations of any agent are not eligible.

interfere with the oral absorption or tolerance of gilteritinib or midostaurin
including difficulty swallowing are not eligible.
- Patient with any serious medical or psychiatric illness that could, in the
investigator's opinion, potentially interfere with the completion of the treatment
according to the protocol are not eligible.
- Patient may not participate in any other therapeutic clinical trials, including
those with other investigational agents not included in this trial during treatment
on this study without prior approval from PrECOG.
