Patients are not considered to have a currently active malignancy if they have completed therapy for more than one year and are considered by their physician to be at less than 30% risk of relapse within one year~* Hyperleukocytosis (leukocytes \> 30,000/µl) at the time of study entry. 1)~* Uncontrolled or significant cardiovascular disease, including any of the following:~  * History of heart failure NYHA class 3 or 4~ * Left ventricular ejection fraction (LVEF) ≤ 40% by echocardiogram (ECHO)~ * History of uncontrolled angina pectoris or myocardial infarction within 12 months prior to screening~ * History of second (Mobitz II) or third degree heart block or any cardiac arrhythmias requiring anti-arrhythmic therapy (beta blockers or digoxin are permitted)~* Inadequate liver function: ALT and AST ≥ 2.5 x ULN), total bilirubin ≥ 1.5 x ULN; Alkaline phosphatase ≥ 2.5 x ULN. Known liver cirrhosis or history of veno-occlusive disease (VOD) or history of Sinusoidal Obstruction Syndrome (SOS)~* Known positivity for HIV, active HBV, HCV or hepatitis A infection (active hepatitis B defined by HBs Ag positivity, active hepatitis C defined by positive virus load)~* Uncontrolled active infection~* Evidence or history of severe non-leukemia associated bleeding diathesis or coagulopathy~* within 100 days after allo-HCTat the time of screening~* clinically relevant Graft-versus-Host-Disease (GvHD) requiring initiation of treatment or treatment escalation within 21 days prior to screening~* Any one of the following ongoing or in the previous 6 months: myocardial infarction, congenital long QT syndrome, Torsades de pointes, arrhythmias (including sustained ventricular tachyarrhythmia), right or left bundle branch block and bifascicular block, unstable angina, coronary/peripheral artery bypass graft, cerebrovascular accident, transient ischemic attack or symptomatic pulmonary embolism; as well as bradycardia defined as \<50 bpms~* QTc interval \>470 msec using the Fredericia correction (QTcF).~* Patients known to be refractory to platelet or packed red cell transfusions as per institutional guidelines, or who are known to refuse or who are likely to refuse blood product support.~* Severe neurologic or psychiatric disorder interfering with ability of giving informed consent~* Known or suspected active alcohol or drug abuse~* No consent for biobanking and for registration, storage and processing of the individual disease-characteristics and course as well as information of the family physician about study participation.~* Pregnancy and lactation~* History of hypersensitivity to the investigational medicinal product or to any drug with similar chemical structure or to any excipient present in the pharmaceutical form of the investigational medicinal product~* Prior treatment with quizartinib~  1. These patients should be treated with hydroxyurea and / or receive leukocytapheresis treatment according to routine practice and are only allowed to enter into the study when leukocyte counts of 30,000/µl or below are reached. If hydroxyurea is not sufficient to control hyperleukocytosis, i.v. application of 100mg cytarabine continuously over 24 hours may be discussed with the Principle Investigator or the Medical Coordinator.

Study Arms:
- MRD-triggered arm (Type: EXPERIMENTAL): 1. Salvage therapy: All patients are randomized upfront and receive one cycle Q-HAM salvage therapy. All patients achieving CR or CRi are allocated according to randomization to either MRD-triggered or prophylactic arm.~   (Duration: one cycle á 21 days followed by up to 3 weeks recovery period if needed, 22-42 days in total)~2. Consolidation therapy: Patients receive one cycle of HAM and are further allocated based on the MRD-results assessed by flow cytometry with a cut of level of 0.1%: if the MRD is negative they remain in the MRD-triggered arm, whereas MRD positive patients cross over to the prophylactic arm.~   (Up to 2 cycles. Duration: two cycles á 28 days each followed by up to two weeks recovery period if needed, 56-84 days in total.)~3. Observation: No treatment will be given in the MRD-triggered arm. (Duration: 48 weeks in total.)~4. Safety follow-up and observational follow-up
- Prophylactic Arm (Type: EXPERIMENTAL): 1. Salvage therapy: All patients are randomized upfront and receive one cycle Q-HAM salvage therapy. All patients achieving CR or CRi are allocated according to randomization to either MRD-triggered or prophylactic arm.~   (Duration: one cycle á 21 days followed by up to 3 weeks recovery period if needed, 22-42 days in total)~2. Consolidation therapy: Patients may receive up to two cycle of Q-HAM. (Up to 2 cycles. Duration: two cycles á 28 days each followed by up to two weeks recovery period if needed, 56-84 days in total.)~3. Maintenance therapy: Quizartinib will be given as single-agent therapy. The dose of quizartinib is aimed to be increased during maintenance therapy. (Up to 12 cycles. Duration: four times three cycles á 28 days, 48 weeks in total.)~4. Safety follow-up and observational follow-up
