About this study

Official title: MLL Rearrangements in Acute Myeloid Leukemia: A Pilot Project to Expand and Study MLL-ENL in NOD SCID Gamma Mice

RATIONALE: Studying samples of bone marrow from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is looking at bone marrow samples from patients with acute myeloid leukemia.

Read the detailed description

OBJECTIVES:

  • To successfully transplant human acute myeloid leukemia (AML) cells into immunocompromised mice for the purpose of expansion of the cells.
  • To harvest the cells and use chromatin immunoprecipitation (ChIP) methods to identify the locations of the protein complexes on the genome.
  • To study the interactions of the Super Elongation Complex (SEC) and Dot1 Complex (DotCom) complexes in human leukemia samples.
  • To compare the genomic targets of the complexes formed by MLL-ENL chimeras to non-MLL-rearranged leukemia samples to normal controls.

OUTLINE: Cryopreserved cells are implanted into NOD SCID gamma mice, expanded, harvested, and studied by chromatin immunoprecipitation (ChIP) methods (using antibodies to ENL, Af9, and AF10). Results are then analyzed by PCR, DNA sequencing, and/or microarray analysis.

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?

Successful transplantation of human acute myeloid leukemia (AML) cells into immunocompromised mice for the purpose of expansion of the cells. 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.
