About this study

Official title: S0106A, Proteomic Signatures Associated With Complete Response (CR) and Complete Continuous Response at One Year (CCR1) Following Cytarabine-Based Induction Chemotherapy in Younger Adult Patients (18-60 Years of Age) With a Newly Diagnosed Non-M3 AML

RATIONALE: Studying samples of bone marrow and blood from patients with cancer in the laboratory may help doctors predict how well patients will respond to treatment.

PURPOSE: This research study studies biomarkers in samples from patients with newly diagnosed acute myeloid leukemia treated with cytarabine-based chemotherapy.

Read the detailed description

OBJECTIVES:

  • Training and testing of multiparameter flow cytometry-based cell signaling signature (FC classifier 1) associated with in vivo primary chemoresistance (i.e., non-complete response [NR]) to standard induction therapy in adult patients ≤ 60 years old with a newly diagnosed non-M3 acute myeloid leukemia (AML).
  • Training and testing of multiparameter flow cytometry-based cell signaling signature (FC classifier 2) associated with complete continuous response at 1 year (CCR1) in adult patients ≤ 60 years old with a newly diagnosed non-M3 AML who are treated with cytarabine-based induction chemotherapy.
  • Identification of signaling signature(s) associated with secondary chemoresistance (i.e., disease relapse) in adult patients ≤ 60 years of age who have longitudinally paired peripheral blood mononuclear cells (PBMC) or bone marrow mononuclear cells (BMMC) samples at diagnosis and at the time of first relapse. (Exploratory)

OUTLINE: Cryopreserved samples are incubated with cytokines (e.g., interleukins), growth factors (e.g., sargramostim [GM-CSF] and filgrastim [G-CSF]), chemotherapeutic agents (e.g., cytarabine, etoposide phosphate), and other modulators. Cells are fixed, permeabilized, and stained with antibodies that recognize extracellular markers in conjunction with intracellular activation-state specific epitopes of designated signaling molecules. Subsequently, cells are analyzed for multiparametric phospho-flow cytometry in a random manner (without knowledge of clinical variables and outcomes) to training and testing sets. Results are then compared with individual patient 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 15 Apr 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?

Response to induction chemotherapy (complete response vs non-complete response) (classifier 1) (time frame: immediate). The study lists 2 primary outcomes in all. 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 NCT01360125, 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 15 Apr 2016.
