The purpose of this single-arm, open label, phase-II trial, is to determine whether the association of Midostaurin to standard induction, consolidation therapy and in maintenance therapy as single agent, is effective in decrease relapse incidence, in patients with CBF-AML. The single-arm, open label, phase-II study is based on data obtained from previous clinical and pre-clinical studies, obtained by use of Midostaurin in patients with Acute Myeloid Leukemia (with or without FLT3 mutations) and in patients with Mast cell disorders (characterized by mutations in the C-KIT gene). The investigators believe that Midostaurin, associated with standard therapy Anthracycline/AraC Induction, to the consolidation regimen with high doses of araC and maintenance therapy to single agent in patients with acute myeloid leukemia core-binding factor can significantly reduce the incidence of recurrence of the disease, occurring in 40-50% of cases treated with standard therapy


In this prospective, Interventional, Single-Arm, Open-Label, Phase-II Trial aims at demonstrating a decrease in the 2-year Relapse Incidence (RI) and in the 2-year Cumulative Relapse Incidence among the Midostaurin-treated patients compared to a cohort of historical controls. The investigators established that a 20% net reduction in the 2-year RI may be a clinically significant goal. So the investigators set our RI objective at 28%. Furthermore, the investigators will assess if the experimental treatment may obtain an increased 5-years Overall, Disease-Free and Event free Survival. The safety profile of Midostaurin given in combination with induction and consolidation chemotherapy and as a single agent in maintenance in CBFL patients will also be assessed.

Inclusion Criteria

Written informed consent must be obtained prior to any screening procedures
Patients must be 18 to 65 years of age at the time of signing informed consent
Patients must have an unequivocal diagnosis of de novo-CBFL, prior to start midostaurin, documented by rearrangement of Core Binding Factor (CBF) genes, namely AML1-ETO and CBFB-MYH11, either with observation of t(8;21)(q22;q22) or inv(16)(p13; q32)/t(16;16)(p13; q32) by conventional cytogenetics or hybridization techniques or detection of fusion genes by PCR-polymerase chain reaction
Patients must be fit to receive an anthracycline/AraC-based induction therapy (i.e. Ara-C 100 mg/m2 or 200 mg/m2 i.v. day, by continuous infusion for 7 days and Idarubicin 12 mg/m2 i.v. day or daunomycin 60 mg/m2 on days 1, 3 and 5)
Patients must have an ECOG-Eastern Cooperative Oncology Group Performance Status of ≤ 2\
Patients must have Total Bilirubin ≤ 1.5 x ULN, and AST or ALT ≤ 2.5 x ULN
Patients must have Serum Creatinine ≤ 1.5 x ULN
Women of child-bearing potential must have a negative pregnancy test before starting the protocol

Exclusion Criteria

Prior therapy for AML with the following exceptions
emergency leukapheresis
emergency treatment for hyperleukocytosis with hydroxyurea for ≤ 7 days
Central nervous system involvement
Presence of any uncontrolled bacterial, viral or fungal infection
Known human immunodeficiency virus (HIV) positive
An active Hepatitis B virus (HBV) or Hepatitis C virus (HCV) infection. Patients whose disease is controlled under antiviral therapy should not be excluded
Presence of other active malignancies
QTc > 470 msec (Bazett formula) on screening ECG
Presence of significant uncontrolled or active cardiovascular disease, specifically including, but not restricted to
Myocardial infarction, unstable angina and/or congestive heart failure within 3 months prior to randomization
History of clinically significant (as determined by the treating physician) atrial arrhythmia or any ventricular arrhythmia
Uncontrolled hypertension
Taking medications that are known to be associated with Torsades de Pointes
History of hypersensitivity to any drugs or metabolites of similar chemical classes as
Pregnancy statements and contraception requirements
the study treatment
Women of child-bearing potential, defined as all women physiologically capable of becoming
pregnant, unless they are using highly effective methods of contraception during dosing and
for at least 4 months after stopping medication. Highly effective contraception methods
Total abstinence (when this is in line with the preferred and usual lifestyle of the
subject). Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation
methods) and withdrawal are not acceptable methods of contraception
Female sterilization (have had surgical bilateral oophorectomy with or without
hysterectomy), total hysterectomy, or tubal ligation at least six weeks before taking
study treatment. In case of oophorectomy alone, only when the reproductive status of
the woman has been confirmed by follow up hormone level assessment
Male sterilization (at least 6 months prior to screening). The vasectomized male
partner should be the sole partner for that subject
Use of oral, injected or implanted hormonal methods of contraception or placement of
an intrauterine device or intrauterine system, or other forms of hormonal
contraception that have comparable efficacy (failure rate <1%), for example hormone
vaginal ring or transdermal hormone contraception. In case of use of oral
contraception women should also add a barrier method of contraception, particularly as
it is currently unknown whether midostaurin may reduce the effectiveness of hormonal
contraceptives. Sexually-active males unless they use a condom during intercourse with
females of reproductive potential or pregnant women and for at least 4 months after
stopping treatment to avoid conception or embryo-fetal harm
