Daunorubicin or Idarubicin With Cytarabine Plus Quizartinib vs Physician's Choice in Newly Diagnosed FLT3-ITD+ AML (Q-SOC)
Randomized Study in Newly Diagnosed AML With FLT3-ITD Comparing Daunorubicin/ Cytarabine or Idarubicin/Cytarabine and Quizartinib to Physician's Choice
The orally administered second-generation bis-aryl urea tyrosine kinase inhibitor quizartinib is very specific for FLT3, has a high capacity for sustained FLT3-inhibition and an acceptable toxicity profile. Furthermore, single agent quizartinib doubled the response rate as compared to standard of care in a randomized study in r/r-AML. Combination therapy of quizartinib with intensive standard induction chemotherapy has been shown to be safe and moreover, single agent quizartinib maintenance therapy is feasible even after allogeneic HCT.
The efficacy of quizartinib in combination with intensive induction and post-remission therapy including allogeneic HCT and single agent quizartinib as maintenance therapy is evaluated by this protocol. This approach is compared in a randomized manner to the current standard of care.

Detailed Description
This is a multicenter, upfront randomized phase III trial of patients with FLT3-ITD positive AML comparing quizartinib in combination with SOC chemotherapy versus treatment according to physician's choice (PhC). Efficacy is assessed by comparing EFS between the quizartinib and the PhC arm of the study.
Primary objective To improve modified event-free survival (mEFS) with Quizartinib added to induction and consolidation therapy followed by single agent maintenance therapy compared to physician's choice (PhC)
Secondary objectives To improve overall survival (OS) with Quizartinib added to conventional therapy compared to physician's choice; To improve remission (including CR/CRi/CRh) rate with Quizartinib added to conventional therapy compared to physician's choice To reduce measurable residual disease (MRD) with Quizartinib added to conventional therapy compared to physician's choice after induction (MRDind), consolidation (MRDcons), before allogeneic hematopoietic cell transplantation (MRDpre-HCT ) and maintenance (MRDmaintenance) therapy Assessment of patient reported outcomes (PRO) after induction, consolidation and maintenance therapy and after two years Evaluation of safety based on duration of neutropenia and leukopenia, incidence of infection, duration of initial hospitalization and number of transfusions (e.g. packed red blood cells and platelets) Cost-effectiveness analysis of the two different treatment schedules from health care payer´s perspective.
Budget impact analysis of introducing effective treatment schedule(s) in everyday clinical practice.

Description
Inclusion Criteria
- Diagnosis of untreated acute myeloid leukemia (AML) according to the WHO 2016 definition

- Not included in other first-line trials
- Non-pregnant and non-nursing women

("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).
- WOCBP must agree to avoid getting pregnant while on therapy: WOCBP must either commit to continued abstinence from heterosexual intercourse or begin and adhere to one acceptable method of birth control (IUD, tubal ligation, or partner's vasectomy) during study and 6 months after end of study/treatment.**
- Men must use a latex condom during any sexual contact with WOCBP, even if they have undergone a successful vasectomy and must agree to avoid to father a child during study and 6 months after end of study/treatment
- Signed written informed consent
- Ability of patient to understand character and consequences of the clinical trial
Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures
In case hyperleukocytosis is not controllable with hydroxyurea, treatment with e.g. cytarabine should be discussed in Germany with the principal investigator and in Spain with the PETHEMA trials office or for patients of both countries with the medical coordinator.
- A high follicle-stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy at investigator's discretion.

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.
Prior treatment for AML, except for the following allowances:
- Leukapheresis;
- Treatment for hyperleukocytosis with hydroxyurea;
- Cranial radiotherapy for central nervous system (CNS) leukostasis;

- Known positivity for HIV, active HBV, HCV or hepatitis A infection (active hepatitis HBV defined by HBsAg positivity, active HCV defined by positive virus load)
- Uncontrolled active infection
- Evidence or history of severe non-leukemia associated bleeding diathesis or coagulopathy
