Brief Summary:
This phase I/II trial studies how well quizartinib and decitabine work in treating participants with FLT3-ITD mutated acute myeloid leukemia or myelodysplastic syndrome that is untreated or has come back. Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving quizartinib and decitabine may work better at treating acute myeloid leukemia and myelodysplastic syndrome.

Acute Myeloid Leukemia With FLT3/ITD Mutation Blasts More Than 10 Percent of Bone Marrow Nucleated Cells Blasts More Than 10 Percent of Peripheral Blood White Cells Myelodysplastic Syndrome Recurrent Acute Myeloid Leukemia Recurrent Myelodysplastic Syndrome Drug: Decitabine Drug: Quizartinib Phase 1 Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the overall response rate (ORR) including CR (complete remission) + CRp (complete remission with incomplete platelet recovery) + CRi (complete remission with incomplete count recovery) + partial remission (PR) within 3 months of treatment initiation of quizartinib and decitabine combination in patients with newly diagnosed or relapsed FLT3-ITD mutated acute myeloid leukemia (AML) or high risk myelodysplastic syndrome (MDS) (> 10% blasts).

II. To determine the safety and maximum tolerable dose (MTD) of this combination.

SECONDARY OBJECTIVES:

I. To determine CR and CR+CRh rates within 3 months of treatment initiation of quizartinib and decitabine combination in patients with newly diagnosed or relapsed AML or or high risk MDS (> 10% blast).

II. To determine the duration of response (DOR), event-free survival (EFS), overall survival (OS), and number of patients bridged to hematopoietic stem cell transplant (HSCT) and median duration to HSCT from the initiation of the combination.

II. To investigate correlations of response to this combination with a pre-therapy, on-therapy, and progression 81-gene panel of gene mutations in AML.

EXPLORATORY OBJECTIVES:

I. To investigate possible relationships between response and non-response to the combination with pretherapy, on-therapy, and progression gene expression signatures.

II. To store and/or analyze surplus blood or tissue including bone marrow, if available, for potential future exploratory research into factors that may influence development of AML and/or response to the combination (where response is defined broadly to include efficacy, tolerability or safety).

OUTLINE: This is a phase I, dose escalation study followed by a phase I study.

Participants receive decitabine intravenously (IV) over 1 hour on days 1-10 and quizartinib orally (PO) every day beginning on day 5 of course 1. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up every 3-6 months for up to 5 years.

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

Inclusion Criteria:

  • Diagnosis of 1) AML (World Health Organization [WHO] classification definition of >= 20% blasts) excluding acute promyelocytic leukemia (APL) or 2) MDS with > 10% blasts (defined by the International Prognostic Scoring System [IPSS] classification).
  • For frontline Cohort: Patients aged >= 60 years old who are not candidates for intensive induction therapy and agree to receive the proposed combination therapy will be enrolled.
  • For relapsed cohort: Patients aged >= 18 years old. (Patients who are candidates for relapse cohort will be enrolled into the study regardless of their fitness for intensive chemotherapy).
  • For frontline cohort: Patients must be chemonaive, i.e. not have received any chemotherapy (except hydrea or 1-2 doses of ara-C for transient control of hyperleukocytosis) for AML or MDS. They may have received transfusions, hematopoietic growth factors or vitamins for an antecedent hematological disorder (AHD) or for AML. Temporary prior measures such as apheresis, all-trans-retinoic acid (ATRA), steroids or hydrea while diagnostic work-up is being performed are allowed and not counted as a prior salvage. Supportive care therapy for MDS (growth factors, transfusions) will not be considered as prior therapy for MDS/AML and these patients will be enrolled to the frontline cohort of the study if they are otherwise eligible.
  • For relapsed cohort: Patients who have received at least one prior therapy for AML or for MDS with > 10% blasts will be eligible. Patients may have received up to 4 prior salvages for AML and/or MDS (defined by the IPSS classification). Prior therapy for AML or MDS will be counted as a prior salvage. Patients who receive MDS directed therapies considered not purely supportive such as HMAs, lenalidomide, investigational therapies, will be enrolled to the salvage cohort if they are otherwise eligible.
  • In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of protocol therapy will be at least 2 weeks for cytotoxic agents or at least 5 half-lives for cytotoxic/noncytotoxic agents. The half-life for the therapy in question will be based on published pharmacokinetic literature and will be documented in the protocol eligibility document.

The QTc interval will be calculated by Fridericia's correction factor (QTcF) at screening and on day 5 prior to the first dose of AC220. The QTcF will be derived from the average QTcF in triplicate. If QTcF > 450 msec on day 5, AC220 will not be given. Patients with congenital long QT syndrome. History or presence of sustained ventricular tachycardia requiring medical intervention.
