Overview
Brief Summary
This is a randomized phase III open-label, multicenter trial evaluating standard induction therapy (daunorubicin [DNR] and cytarabine [Ara-C]) and consolidation therapy (high-dose cytarabine [HDAC]) with or without dasatinib in adult patients with newly diagnosed CBF-AML
Detailed Description
This is a randomized phase III open-label, multicenter trial evaluating standard induction therapy (daunorubicin \[DNR\] and cytarabine \[Ara-C\]) and consolidation therapy (high-dose cytarabine \[HDAC\]) with or without dasatinib in adult patients with newly diagnosed CBF-AML; in the investigational arm, consolidation therapy is followed by a one-year maintenance therapy with dasatinib. Patients with molecular disease persistence or molecular relapse as assessed by quantitative RQ-PCR for the CBF fusion transcripts will be eligible for hematopoietic stem cell transplantation before overt hematologic relapse occurs. Primary endpoint is event-free survival. AML patients will be assessed for the CBF fusion genes in one of two AMLSG central laboratories within 48 hours of diagnosis, and only patients with CBF-AML will be enrolled.

Eligibility Criteria
Inclusion Criteria
- •Core-binding factor (CBF) AML with molecular diagnosis of RUNX1-RUNX1T1 fusion transcript resulting from t(8;21)(q22;q22.1) (or a variant form) or of CBFB-MYH11 fusion transcript resulting from inv(16)(p13.1q22)/t(16;16)(p13.1;q22) as assessed in one of the central AMLSG reference laboratories (Ulm, Hannover)
- •Age ≥ 18; there is no upper age limit
- •No prior chemotherapy for leukemia except hydroxyurea for up to 5 days during the diagnostic screening phase
- •Non-pregnant and non-nursing. Due to the unknown teratogenic potential of dasatinib in humans, pregnant or nursing patients may not be enrolled. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test within a sensitivity of at least 25 mIU/mL with-in 72 hours prior to registration. Women of child-bearing potential must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control - one highly effective method (e.g., IUD, hormonal, tubal ligation, or partner's vasectomy), and one additional effective method (e.g., latex condom, diaphragm, or cervical cap) - AT THE SAME TIME, at least four weeks before she begins dasatinib therapy. "Women of childbearing potential" is defined as a sexually active mature woman who has not undergone a hysterectomy or who has had menses at any time in the preceding 24 consecutive months.
- •Men must agree not to father a child and must use a latex condom during any sexual contact with women of childbearing potential while taking dasatinib and for 3 months after therapy is stopped, even if they have undergone a successful vasectomy.
- •Signed written informed consent.
Exclusion Criteria
- •Performance status WHO \>2
- •Pulmonary edema and/or pleural/pericardial effusion within 14 days of day
- •If edema/effusion resolves to CTC Grade ≤1, patients can be treated with dasatinib.
- •Patients with ejection fraction \<50% by echocardiography within 14 days of day 1
- •Organ insufficiency (creatinine \>1.5x upper normal serum level; bilirubin, AST or AP \>2.5x upper normal serum level; heart failure NYHA III/IV; severe obstructive or restrictive ventilation disorder)
- •Uncontrolled infection
- •Patients with a "currently active" second malignancy other than non-melanoma skin cancers. Patients are not considered to have a "currently active" malignancy, if they have completed therapy and are considered by their physician to be at less than 30% risk of relapse within one year.
- •Severe neurological or psychiatric disorder interfering with ability of giving an informed consent
- •Known positive for HIV, active HBV, HCV, or Hepatitis A infection
- •Bleeding disorder independent of leukemia
Arms & Interventions
Standard arm
Patients will receive induction therapy with daunorubicin 60 mg/m2/day administered on days 1-3 (when daunorubicin is not available due to supply shortage: Idarubicin 12mg²/day on days 1,3,5) and cytarabine 200 mg/m2/day administered by continuous IV infusion on days 1-7. Patients achieving PR only at the end of cycle 1 will receive a second induction cycle with daunorubicin 50 mg/m2/day (when daunorubicin is not available due to supply shortage: Idarubicin 10 mg²/day on days 1 and 3) administered on days 1-3 and cytarabine 200 mg/m2/day administered by cont. IV infusion daily on days 1-5. Patients will receive 4 cycles of consolidation therapy. Consolidation therapy consists of high-dose cytarabine 3 g/m2 (\>60 years: 1 g/m2) q12h, days 1-3 administered intravenously over three hours. Follow-up period: There is no maintenance therapy in the standard arm. Patients will be closely followed, in particular for molecular disease persistence or molecular relapse.
