About this study
Official title: Epigenetic Alterations in AML
RATIONALE: Studying samples of blood or tumor tissue from patients with cancer in the laboratory may help doctors learn about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This research study is studying biomarker changes in samples from young patients with acute myeloid leukemia.
Read the detailed description
OBJECTIVES:
- Map key histone modifications and cytosine methylation in leukemia cell lines with defined oncogenic mutations.
- Acquire genome-wide maps of key histone modifications and cytosine methylation for primary leukemia in samples from patients with acute myeloid leukemia (AML).
- Investigate functional relationships between genetic and epigenetic landscapes in AML.
OUTLINE: Archived samples are analyzed in vivo and in vitro (cell line) for histone modification and cytosine methylation. Genome-wide locations of 5 histone modifications are analyzed using chip-Seq, as well as DNA methylation analysis at nucleotide-resolution by high-throughput bisulfite sequencing. These epigenetic data are correlated with genomic data (sequence analysis, expression array, SNP array).

Questions about this trial
What is this clinical trial studying?
An observational study of Leukemia, run by Children's Oncology Group.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 May 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relationships between genetic and epigenetic landscapes in AML. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2016.
