Brief Summary:
This phase I/II trial studies the side effects and best dose of quizartinib when given with azacitidine and to see how well they work in treating patients with myelodysplastic syndrome or myelodysplastic/myeloproliferative neoplasm with FLT3 or CBL mutations. Chemotherapy drugs, such as azacitidine, 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. Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine and quizartinib may help to control myelodysplastic syndrome or myelodysplastic/myeloproliferative neoplasm.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the safety, tolerability and maximum tolerable dose (MTD) of quizartinib in combination with azacytidine.

II. To assess overall response (ORR) rate to quizartinib in combination with azacitidine.

SECONDARY OBJECTIVES:

I. To assess overall survival (OS), duration of response, leukemia-free survival (LFS), relapse-free survival (RFS) and safety profile.

II. Correlative studies.

OUTLINE: This is a phase I, dose-escalation study of quizartinib followed by a phase II study.

Patients receive azacitidine subcutaneously (SC) or intravenously (IV) over about 30 minutes on days 1-5 and quizartinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Primary Outcome Measures :
  1. Overall response rate [ Time Frame: At least 4 cycles of therapy in the absence of progression (1 cycle = 28 days) ]
    Will be defined as complete remission, partial remission, complete remission with incomplete count recovery, marrow compete remission or hematological improvement. Will be estimated for all patients along with the 95% credible interval.

  2. Overall survival [ Time Frame: Time from treatment start till death or last follow-up, assessed up to 2 years ]
    Will be listed and summarized by the Kaplan-Meier estimator.

  3. Duration of response [ Time Frame: Duration from the first documented onset of partial response or complete response to the date of progressive disease/relapse, assessed up to 2 years ]
    Will be listed and summarized by the Kaplan-Meier estimator.

  4. Relapse-free survival [ Time Frame: Time from start of response to the date of event defined as the first documented progressive disease/relapse or death, whichever comes first, assessed up to 2 years ]
    Will be listed and summarized by the Kaplan-Meier estimator.

  5. Leukemia free survival [ Time Frame: Time from treatment start to the time of progression to leukemia or death, assessed up to 2 years ]
    Will be listed and summarized by the Kaplan-Meier estimator.

  6. Incidence of adverse events (AEs) [ Time Frame: Up to 2 years ]
    The severity of the toxicities will be graded according to the latest version of National Cancer Institute Common Terminology Criteria for Adverse Events. The number and percent of subjects with treatment-emergent adverse events will be summarized according to intensity and drug relationship, and categorized by System Organ Class and preferred term by dose level/Part. All reported AEs that occur after signing informed consent will be included in the analysis of all reported AEs. Exposure to study drug and reasons for discontinuation of study drug will be tabulated.

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 myelodysplastic syndrome (MDS) or MDS/myeloproliferative neoplasm (MPN) including chronic myelomonocytic leukemia (CMML) according to World Health Organization (WHO)
  • For hypomethylating agent naive patients: int-2 or higher by International Prognostic Scoring System (IPSS) or > 5% bone marrow blasts if MDS or dysplastic CMML (white blood cell [WBC] < 13 x 10^9/L). Patients with proliferative (WBC >= 13 x 10^9/L) CMML or MDS/MPN, or those with dysplastic CMML with high-risk molecular features (mutations in ASXL1, TP53 or more than 3 mutations) are also eligible independently of IPSS risk score or bone marrow blast percentage
  • For patients with prior hypomethylating agent therapy: no response after 6 cycles of azacitidine, decitabine, guadecitabine or ASTX727 or relapse or progression after any number of cycles
  • Detectable FLT3-ITD mutation in bone marrow and/or peripheral blood, or presence of CBL exon 8 or 9 deletions or point mutations
  • Serum creatinine =< 2 x upper limit of normal (ULN)
  • Total bilirubin < 2 x ULN (will allow less than 5 x ULN if Gilbert's at investigator's discretion)
  • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) =< 3 x ULN
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2
  • Patient (or patient's legally authorized representative) must have signed an informed consent document indicating that the patient understands the purpose of and procedures required for the study and is willing to participate in the study

Subjects with prolonged QTcF interval in the setting of RBBB (right bundle branch block) may participate upon review and approval by the principal investigator and following evaluation by cardiology consult
  • Patients with congenital long QT syndrome
  • History or presence of sustained ventricular tachycardia requiring medical intervention
  • Any history of clinically significant ventricular fibrillation or torsades de pointes
  • Known history of second- or third-degree heart block (may be eligible if the patient currently has a pacemaker)

  • Female patients who are pregnant or lactating
  • Patients with reproductive potential who are unwilling to following contraception requirements (including condom use for males with sexual partners, and for females: prescription oral contraceptives [birth control pills], contraceptive injections, intrauterine devices [IUD], double-barrier method [spermidical jelly or foam with condoms or diaphragm], contraceptive patch, or surgical sterilization) throughout the study
  • Female patients with reproductive potential who do not have a negative urine or blood beta-human chorionic gonadotropin (beta HCG) pregnancy test at screening
  • Patients receiving any other concurrent investigational agent or chemotherapy, radiotherapy, or immunotherapy
  • Patients known to be positive for hepatitis B surface antigen expression or with active hepatitis C infection (positive by polymerase chain reaction or on antiviral therapy for hepatitis C within the last 6 months). Patients with history of human immunodeficiency virus (HIV) disease are also excluded from the study
