Inclusion criteria

• Core binding factor (CBF) AML with molecular diagnosis of RUNX1-RUNX1T1 fusion transcript resulting from t(8;21)(q22;q22) (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.
• Age ≥ 18; there is no upper age limit.
• No prior chemotherapy for leukemia except hydroxyurea for up to 5 days during the diag-nostic 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 poten-tial (WOCBP) must have a negative serum or urine pregnancy test within a sensitivity of at least 25 mIU/mL within 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 con-tact with women of childbearing potential while taking dasatinib and for 4 weeks after therapy is stopped, even if they have undergone a successful vasectomy.
• Signed written informed consent

• Pulmonary edema and/or pleural/pericardial effusion within 14 days of Day 1. 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
• Severe neurological or psychiatric disorder interfering with ability of giving an informed consent
• Known positive for HIV
• Bleeding disorder independent of leukemia
• No consent for registration, storage and processing of the individual disease-characteristics and course
