Brief Summary:
This is a multicenter, prospective, non-randomized, Phase I-II trial to assess the efficacy and safety of the combination of oral quizartinib and FLAG-IDA chemotherapy schedule (FLAG-QUIDA regimen) in first relapsed/refractory AML (acute myeloid leukemia) patients.

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Drug: Quizartinib Drug: Fludarabine Drug: Cytarabine Drug: Idarubicin Drug: glycosylated G-CSF Phase 1 Phase 2

Detailed Description:

Patients of approximately 20 sites (in Spain and Portugal) will receive FLAG-QUIDA regimen followed by transplantation, when possible, with up to 3 optional consolidation cycles. All patients in CR/CRi (complete remission / complete remission with incomplete hematologic recovery) will receive a maintenance schedule.

A Phase I (dose escalation) will be performed at 40 mg x 14 days of quizartinib in the first 3 patients, and if no dose-limiting toxicity (DLT) is observed, the next cohort of patients will receive 60 mg x 14 days. There is also the possibility of de-escalation cohorts at 60 mg x 7 days and at 40 mg x 7 days. Patients participating in the Phase I will receive the allocated dose level, and therefore, they must not receive strong CYP3A4 inhibitors concomitantly with quizartinib The Phase II will include 68 patients treated at the RP2D (recommended phase 2 dose). A 1-year maintenance schedule starting at 30 mg will be increased to 60 mg/day if appropriate.

Patients will be followed up for a minimum period of 1 year since the first visit of the last patient included.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 80 participants
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description:

The study consists of a dose escalation-dose finding part (phase I) and a phase II part.

Subjects will have an induction of 1 cycle, by an alloSCT (allogeneic hematopoietic stem cell transplantation) in CR/CRi, when possible, with up to 3 optional HiDAC (high dose Cytarabine ) consolidation cycles. All patients in CR/CRi will receive a maintenance schedule (12 months, 12 cycles).

The phase I portion will progress from starting level dose 1 (40mg 14 days) to level dose 2 (60 mg 14 days). De-escalation to level dose -1 (60mg 7 days) or level dose -2 (40mg 7 days) may be necessary to be explored.

Once the RP2D is established, the phase II will start.
