Brief Summary:
This phase II trial studies how well midostaurin and decitabine work in treating older patients with newly diagnosed acute myeloid leukemia and FLT3 mutations. Midostaurin and decitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the complete response rate for elderly patients with FLT3 mutated acute myeloid leukemia (AML) using midostaurin and decitabine.

SECONDARY OBJECTIVES:

I. Determine the 1-year overall survival (OS) and progression free survival (PFS) rates.

II. Determine overall response rates in patients treated with this regimen. III. Determine the complete response duration in patients treated with this regimen.

IV. Assess the safety and toxicity of this regimen based on National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

TERTIARY OBJECTIVES:

I. Assess the prognostic and predictive factors (FLT3 internal tandem duplication [ITD] versus [vs] tyrosine kinase domain [TKD] mutation) for patients treated with this regimen.

II. Explore genetic targets for this disease.

OUTLINE:

Patients receive decitabine intravenously (IV) over 1 hour on days 1-5 and midostaurin orally (PO) twice daily (BID) on days 8-21 of courses 1 and 2, and on days 1-28 of each subsequent course. Patients failing to achieve complete response (CR)/complete response with incomplete recovery (CRi)/partial response (PR)/morphologic leukemia-free state by end of course 2 receive midostaurin PO BID on days 1-28. Patients achieving CR/CRi/PR/morphologic leukemia-free state by end of course 8 may continue on current regimen. Patients failing to achieve a CR/CRi/PR/ morphologic leukemia-free state in bone marrow blasts by end of course 8 go to event monitoring. Treatment repeats every 28 days for up to 18 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for up to 2 years.

Primary Outcome Measures :
  1. Proportion of complete responses to therapy, where a success is defined as a CR or CRi as the objective status [ Time Frame: Up to 2 years ]
    The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial confidence intervals for the true success proportion will be calculated.


Secondary Outcome Measures :
  1. Duration of complete response, defined for all evaluable patients who have achieved a CR or CRi as the date at which the patient's objective status is first noted to be a CR or CRi to the earliest date relapse is documented [ Time Frame: Up to 2 year ]
    The distribution of duration of complete response will be estimated using the method of Kaplan-Meier. If there are a sufficient number of CR/CRi, a landmark analyses may be performed to compare duration of CR/CRi in patients who first achieved a CR/CRi at 2 months vs those who first achieved a CR/CRi at 8 months.

  2. Incidence of adverse events, graded according to the NCI CTCAE version 4.0 [ Time Frame: Up to 2 years ]
    The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns. Additionally, the relationship of the adverse event(s) to the study treatment will be taken into consideration.

  3. OS [ Time Frame: Time from registration to death due to any cause, assessed up to 2 years ]
    Estimated using the method of Kaplan-Meier. In addition, the overall survival rate at 1 year after registration will be reported.

  4. Overall response rate, estimated by the total number of complete or partial responses (CR, CRi, morphologic leukemia-free state, or PR) divided by the total number of evaluable patients [ Time Frame: Up to 2 years ]
    Exact binomial 95% confidence intervals for the true overall response rate will be calculated.

  5. PFS [ Time Frame: Time from registration to the time of relapse or death due to any cause, assessed up to 2 years ]
    Estimated using the method of Kaplan-Meier. In addition, the progression-free survival rate at 1 year after registration will be reported.


Other Outcome Measures:
  1. FLT3 mutation by ITD vs. TKD vs. both, assessed by polymerase chain reaction (PCR), western blot, and flow cytometry [ Time Frame: Up to day 1 of course 9 ]
    Prognostic and predictive factors including age and FLT3 mutation by ITD vs. TKD vs. both will be assessed. These factors will be summarized and used to help characterize the types of patients accrued to this trial. In addition, differences in the distributions of these risk factors by clinical outcome will be explored (CR/CRi vs. not, OS and disease-free survival). Nonparametric quantitative comparisons by group will be made as appropriate (Fisher's exact or Wilcoxon rank sum). Kaplan-Meier methods and log rank statistics will be used to compare between groups for time to- event measures.

  2. Minimal residual disease (MRD) status, assessed by PCR for FLT3 mutation (if FLT3 is repeated) or flow cytometry [ Time Frame: Up to day 1 of course 9 ]
    MRD status will be correlated with response using Fisher's exact test. In addition, the relationship between MRD status (positive vs. negative) and disease-free survival will be evaluated using landmark analyses.
