  Purpose

The purpose of this study is to determine the clinical benefit of ASP2215 therapy in patients with FMS-like tyrosine kinase (FLT3) mutated acute myeloid leukemia (AML) who are refractory to or have relapsed after first-line AML therapy as shown with overall survival compared to salvage chemotherapy.

This study will also determine the overall efficacy in event-free survival (EFS) and complete remission (CR) rate of ASP2215 compared to salvage chemotherapy.

Detailed Description:

Subjects considered an adult according to local regulations at the time of signing informed consent may participate in this study. Subjects will be randomized in a 2:1 ratio to receive ASP2215 or salvage chemotherapy. Subjects will enter the screening period up to 14 days prior to the start of treatment. Prior to randomization, a salvage chemotherapy regimen will be pre-selected for each subject; options will include low-dose cytarabine (LoDAC), azacitidine, mitoxantrone, etoposide, and intermediate-dose cytarabine (MEC), or fludarabine, cytarabine, and granulocyte colony-stimulating factor (G-CSF) with idarubicin (FLAG-IDA). The randomization will be stratified by response to first-line therapy and pre-selected salvage chemotherapy. Subjects will be administered treatment over continuous 28-day cycles.

After treatment discontinuation, subjects will have an end-of-treatment visit within 7 days after treatment discontinuation, followed by a 30-day follow-up for safety, in which a telephone contact with the subject is sufficient unless any assessment must be repeated for resolution of treatment-related AEs. After that, long term follow-up will be done every 3 months up to 3 years from the 30 day follow-up.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subject has a diagnosis of primary acute myeloid leukemia (AML) or AML secondary to myelodysplastic syndrome (MDS) according to WHO classification (2008) as determined by pathology review at the treating institute.
  • Subject is refractory to or relapsed after first-line AML therapy (with or without hematopoietic stem cell transplant (HSCT)).

    • Refractory to first-line AML therapy is defined as:

      1. Subject did not achieve complete remission/complete remission with incomplete hematologic recovery/complete remission with incomplete platelet recovery (CR/CRi/CRp) under initial therapy. A subject eligible for standard therapy must receive at least one cycle of an anthracycline containing induction block in standard dose for the selected induction regimen. A subject not eligible for standard therapy must have received at least one complete block of induction therapy seen as the optimum choice of therapy to induce remission for this subject.

    • Untreated first hematologic relapse is defined as:

      1. Subject must have achieved a CR/CRi/CRp (criteria as defined by [Cheson et al, 2003], see Section 5.3) with first line treatment and has hematologic relapse.
  • Subject is positive for FLT3 mutation in bone marrow or whole blood as determined by the central lab. A subject with rapidly proliferative disease and unable to wait for the central lab results can be enrolled based on a local test performed after completion of the last interventional treatment. Subjects can be enrolled from a local test result if they have any of the following FLT3 mutations: FLT3 internal tandem duplication (ITD), FLT3 tyrosine kinase domain (TKD)/D835 or FLT3- TKD/I836.
