About this study

Official title: Proteomic Signature Associated With Clinical Response to Cytarabine Based Induction Therapy in Patients With AML 56 Years and Older

RATIONALE: Studying samples of blood and tissue from patients with cancer treated with cytarabine in the laboratory may help doctors learn more about the effects of cytarabine on cells. It may also help doctors understand how well patients respond to treatment.

PURPOSE: This research trial studies biomarkers associated with response to cytarabine in samples from older patients with acute myeloid leukemia.

Read the detailed description

OBJECTIVES:

  • Refinement and testing of a multiparameter flow cytometry-based cell-signaling signature (FC classifier) associated with in vivo likelihood of complete response (CR) to cytarabine-based induction chemotherapy in elderly patients (56 years and older) newly diagnosed with non-M3 acute myeloid leukemia (AML).
  • Identification of cell-signaling signature(s) associated with continuous CR to cytarabine-based induction chemotherapy at one year (CCR1) in adult patients 56 years and older with a newly diagnosed non-M3 AML.
  • Identification of cell-signaling signature(s) associated with relapse-free survival at one year (RFS1) in adult patients 56 years and older with a newly diagnosed non-M3 AML who received cytarabine-based induction chemotherapy and achieved CR.
  • To investigate changes in cell-signaling signature(s) between matched pre- and post-treatment specimens of relapsed/refractory patients.

OUTLINE: This is a multicenter study.

Cryopreserved specimens are incubated with cytokines (e.g., interleukins), growth factors (e.g., sargramostim or filgrastim), and chemotherapeutic agent (e.g., cytarabine, etoposide) and other modulators. Cells are then fixed, permeabilized, and stained with antibodies that recognize extracellular markers (for example, surface phenotypic markers such as clusters of differentiation, drug transporters, and receptors) in conjunction with intracellular activation-state-specific epitopes of designated signaling molecules. Subsequently, cell are analyzed by phospho-flow cytometry (FC) in a random manner (without knowledge of clinical variables and outcomes) to a training set (complete pre-specified FC) versus a testing set. Cells are also analyzed by proteomic assays. Results are then compared with individual patient scores, including predicted clinical outcomes.

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?

Response to induction chemotherapy: complete response (CR) vs non-complete response (NR) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01338974, which also lists 2 linked publications.

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.
