Midostaurin Associated With Standard Chemotherapy in Patients With Core-binding Factor Leukemia

• Status: Recruiting
• Trial end date: 2025-12-31
• Target enrollment: 0
• Participant gender: All

Summary

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

Criteria

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:

1. emergency leukapheresis

2. 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:

1. Myocardial infarction, unstable angina and/or congestive heart failure within 3 months prior to randomization

2. History of clinically significant (as determined by the treating physician) atrial arrhythmia or any ventricular arrhythmia

3. Uncontrolled hypertension

4. 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 the study treatment.

• Pregnancy statements and contraception requirements:

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 include:

• 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.
