説明
Inclusion Criteria:
All of the following:
- Patient must have non-M3 AML or MDS
An adverse risk karyotype defined by:
- Complex karyotype by cytogenetics, or
- Deletion of all or part of chromosome 5, 7, 12, or 17 defined by FISH or cytogenetics, or
- Somatic TP53 mutation
All of the following:
- Patient must have an ECOG performance status ≤ 2.
- Patient must have >10% disease burden measured by cytomorphology, flow cytometry, or cytogenetics.
- Patient must have peripheral white blood cell count < 50,000/mcl.
Patient must have adequate organ function, defined as:
- Total bilirubin < 1.5 x ULN
- AST/ALT < 2.5 x ULN
- Serum creatinine < 2.0 x ULN
- Patient must have undergone ≤ 2 cycles of prior hypomethylating agent (decitabine or azacitidine).
- Patient must be enrolled in HRPO# 201011766 ("Tissue Acquisition for Analysis of Genetic Progression Factors in Hematologic Diseases").
- Patient must be > 18 years of age.
- Patient must be able to understand and willing to sign an IRB-approved written informed consent document.
Exclusion Criteria:

- Patient must not have undergone prior allogeneic stem cell transplant
- Patient must not have any uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, ongoing or active graft-versus-host disease (GVHD), congestive heart failure of New York Heart Association (NYHA) class 3 or 4, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situation that would limit compliance with study requirements
- Patient must not have had radiation therapy within 14 days of enrollment
- Patient must not have received any chemotherapy within 21 days of enrollment and any acute treatment-related toxicities must have returned to baseline. Patients may be receiving hydrea at time of enrollment.

介入・治療 |
|---|---|
|
実験的:Decitabine
Patients receive decitabine IV over 1 hour on days 1-10 of a 28-day cycle.
Treatment continues for 2 cycles.
Patients then receive decitabine IV over 1 hour on days 1-10, 1-5, or 1-3 (depending on response).
Treatment continues in the absence of disease progression or unacceptable toxicity.

Correlation of Patient Specific Mutations With Overall Response Rate
時間枠:4 months (4 treatment cycles)
|
-Best response after 4 treatment cycles as assessed according to International Working Group (IWG) criteria; bone marrow for gene sequencing will be collected at baseline; mutations will be correlated with overall response rate --Complete remission (CR), Complete remission with incomplete hematologic recovery (CRi), Marrow complete remission (mCR), Partial remission (PR), Stable disease (SD), Progressive disease (PD) |
4 months (4 treatment cycles)

Compare Outcomes of a 10-day Decitabine Per Cycle Regimen to a 5-day Regimen (Historical Controls)
時間枠:4 months (4 treatment cycles)
|
The overall response rate (CR/CRi/mCR/PR) and complete response rate (CR/CRi/mCR) will be compared with historical controls.
Response assessed according to IWG criteria.
|
4 months (4 treatment cycles)
|
|
Rate of Mutation Clearance During Treatment
時間枠:Up to Day 56
|
Samples collected at baseline and after 10, 28 and 56 days of therapy; the rate of mutation clearance was measured as mean VAF change per day of treatment and was estimated using linear mixed model for repeated measurement data .
