A Study of Gilteritinib (ASP2215) Combined With Chemotherapy in Children Adolescents and Young Adults With FMS-like Tyrosine Kinase 3 (FLT3)/Internal Tandem Duplication (ITD) Positive Relapsed or Refractory Acute Myeloid Leukemia (AML)

Brief description of study

The purpose of the phase 1 portion (dose escalation) of the study will be to establish an optimally safe and biologically active recommended phase 2 dose (RP2D) and/or to determine maximum tolerated dose (MTD) for gilteritinib in sequential combination with fludarabine, cytarabine and granulocyte colony-stimulating factor (FLAG). The purpose of the phase 2 portion (dose expansion) is to determine complete remission (CR) rates and composite complete remission (CRc) rates after two cycles of therapy. The study will also assess safety, tolerability and toxicities of gilteritinib in combination with FLAG, evaluate FLT3 inhibition, assess pharmacokinetics (PK), perform serial measurements of minimal residual disease, obtain preliminary estimates of 1-year event free survival (EFS) and overall survival (OS) rate and assess the acceptability as well as palatability of the formulation.

One cycle is defined as 28 days of treatment. A participant completing 2 cycles in phase 1 or 2 will have the option to participate in long term treatment (LTT) with gilteritinib (for up to 2 years).
