About this study

Official title: Childhood Cancer Therapeutically Applicable Research to Generate Effective Treatments (TARGET) Initiative High-Risk ALL Pilot Project: Application of Array-Based Methods and Gene Re-Sequencing to Identify Candidate Molecular Targets for High-Risk Pediatric Acute Lymphoblastic Leukemia

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

PURPOSE: This laboratory study is looking at lymphoblasts in young patients with high-risk acute lymphoblastic leukemia.

Read the detailed description

OBJECTIVES:

  • Identify regions of copy number abnormalities (CNA) and uniparental disomy in leukemic lymphoblasts from pediatric patients with high-risk acute lymphoblastic leukemia (ALL) using Affymetrix GeneChip Mapping 500K array sets. (Pilot project)
  • Identify regions of CNA and loss-of-heterozygosity using Affymetrix SNP 6.0 microarrays. (Expansion project)
  • Define gene expression profiles for leukemic lymphoblasts using Affymetrix U133 Plus 2.0 arrays.
  • Assess the global expression of microRNAs in leukemic lymphoblasts using microRNA gene chips.
  • Utilize array-generated gene expression data and data for CNAs and uniparental disomy to prioritize candidate genes and genomic regions for resequencing.
  • Characterize epigenomic profiles using the HpaII tiny fragment Enrichment by Ligation-mediated PCR (HELP) assay. (Expansion project)
  • Discover candidate therapeutic targets for these patients by identifying genes that are consistently mutated in leukemic lymphoblasts using high-throughput focused gene resequencing. (Pilot project)
  • Discover candidate therapeutic targets for these patients by next generation sequencing technologies, including whole genome, whole transcriptome, and whole exome. (Expansion project)

OUTLINE: This is a multicenter study.

Banked biological samples (bone marrow and peripheral blood) are analyzed using gene expression profiling, single-nucleotide polymorphism and genotyping assays, DNA copy number and loss of heterozygosity estimates, epigenetic profiling, and gene resequencing.

PROJECTED ACCRUAL: A total of 150 patient samples will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

An observational study of Leukemia, run by Children's Oncology Group at 1 site in United States.

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 17 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Identification of regions of copy number abnormalities (CNA) and uniparental disomy in leukemic lymphoblasts using Affymetrix GeneChip Mapping 500K array sets. The study lists 7 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 17 May 2016.
