About this study

Official title: S0106B, Stem Cell Origin in AML: Prognostic and Therapeutic Implications

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

PURPOSE: This research trial studies bone marrow samples from women with acute myeloid leukemia.

Read the detailed description

OBJECTIVES:

  • Estimate the proportion of acute myeloid leukemia (AMLs) that originate in CD33+ precursors or in which uncontrolled growth is limited to CD33+ precursors.
  • Explore whether there is an association between the cellular origin of AML (i.e., origination in CD33+ precursors or not) and cytogenetic, molecular, and other patient characteristics.
  • Explore whether overall survival (OS), event-free survival (EFS), disease-free survival (DFS), response rate (RR), or relapse rate is improved for patients with AMLs that originate in CD33+ precursors or in which uncontrolled growth is limited to CD33+ precursors compared to patients with clonally involved cells not detected.

OUTLINE: Archived bone marrow samples are analyzed for CD33+ progenitors, X-chromosome inactivation, and somatic mutations (t(8;21), inv(16), FLT3/ITD, NPM1, CEBPA, KIT) by fluorescence-activated cell sorting, long-term culture in hypoxic condition in cytokine-containing liquid media, and flow cytometry. Results are then compared with each patient clinical data.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Association between CD33+ precursors and cytogenetic and/or molecular risks using Fisher's exact test

    Measured: May 2012

  2. Relationship between emergence of individual mutations [t(8;21), inv(16), FLT3/ITD, NPM1, CEBPA, and KIT], clonality, and stage of cell differentiation using Fisher's exact test

    Measured: May 2012

  3. Associations between survival outcomes (OS, EFS, DFS, RR, and relapse rate) and CD33+ restriction using regression analysis

    Measured: May 2012

Questions about this trial

What is this clinical trial studying?

An observational study of Leukemia, run by SWOG Cancer Research Network.

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 6 Mar 2015. 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?

Association between CD33+ precursors and cytogenetic and/or molecular risks using Fisher's exact test (time frame: May 2012). The study lists 3 primary outcomes in all. 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 6 Mar 2015.
