Genomic Predictors of Decitabine Response in Patients With Acute Myeloid Leukemia or Myelodysplastic Syndromes
2018年9月5日 更新者:Washington University School of Medicine
Genomic Predictors of Decitabine Response in AML/MDS
This clinical trial studies potential genetic markers which might be used to predict which patients with acute myeloid leukemia or myelodysplastic syndromes respond to decitabine.
This study will contribute to the efforts to find effective and less toxic therapies to provide durable remissions in a significant proportion of elderly AML patients.

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的: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
大体时间: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) |

Compare Outcomes of a 10-day Decitabine Per Cycle Regimen to a 5-day Regimen (Historical Controls)
大体时间: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
大体时间: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 .
