S9031-S9333-S0112-S0301-A Biomarkers Associated With Response to Cytarabine in Samples From Older Patients With Acute Myeloid Leukemia

March 5, 2015 updated by: Southwest Oncology Group

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.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Response to induction chemotherapy: complete response (CR) vs non-complete response (NR)
Time Frame: 1 year
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Complete continuous response at one year (CCR1)
Time Frame: 1 year
1 year
Relapse-free survival at one year (RFS1)
Time Frame: 1 year
1 year

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
