About this study

Official title: Single Nucleotide Polymorphisms and Relapse Risk in Standard Risk ALL

This laboratory study is looking at DNA in tumor tissue samples from young patients with acute lymphoblastic leukemia. DNA analysis of tumor tissue may help doctors predict how well patients will respond to treatment

Read the detailed description

PRIMARY OBJECTIVE:

  1. To validate significant associations between SNPs and treatment outcome and toxicity on Children's Cancer Group (CCG)-1891 on an independent sample set from a successor CCG study for standard risk acute lymphoblastic leukemia (ALL), CCG-1952.

II. To evaluate the role of SNPs in drug metabolizing enzymes and the development of veno-occlusive disease in patients on CCG-1952.

III. To evaluate interactions among genotypes and other risk factors for treatment response in a combined data set of CCG-1891 and CCG-1952 with recently developed analytic tools for high dimensional data.

IV. To develop predictive models utilizing genetic information obtained in Aim 1.1 and clinical data to predict treatment response and toxicity.

OUTLINE:

Tumor tissue samples undergo genotype assessment on the Pyrosequencing platform. Contingency tables and X^2 test performs a univariate analysis of the risk of relapse and genotype, and multivariable analyses using logistic regression. Cox proportional hazards evaluate the risk of relapse given genotype and other confounders. Genotype patterning, classification and regression trees, and multifactor dimensionality reduction evaluates for patterns of single nucleotide polymorphisms associated with toxicity and relapse risk.

What is being measured

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

  1. Leukemia Relapse

    Contingency tables will be used to tabulate the relationship between relapse and genotype, race, leukemia cytogenetics, day 7 bone marrow status, and treatment arm

    Measured: Day 7

  2. Development of veno-occlusive disease in patients on CCG-1952

    Classification and Regression Trees (CART), genotype patterning, Multifactor Dimensionality Reduction (MDR) techniques will be used to identify SNP combinations associated with risk of relapse and VOD

    Measured: Day 28

  3. Development of a predictive model of leukemia relapse

    Predictive models will be developed utilizing genetic information obtained in Aim 1.1 and clinical data to predict treatment response

    Measured: Day 28

  4. Development of a predictive model of leukemia toxicity

    Predictive models will be developed utilizing genetic information obtained in Aim 1.1 and clinical data to predict treatment toxicity.

    Measured: Day 28

Secondary outcomes (1)
  1. Development of grade III/IV toxicity as defined by the CCG toxicity criteria

    Contingency tables will be used to tabulate categorical toxicities and toxicity severity grade.

    Measured: Day 28

Questions about this trial

What is this clinical trial studying?

An observational study of Childhood Acute Lymphoblastic Leukemia in Remission and Recurrent Childhood Acute Lymphoblastic 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?

The sponsor lists 1 inclusion and 0 exclusion criteria. 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 Aug 2022. 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?

Leukemia Relapse (time frame: Day 7). The study lists 4 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 15 Aug 2022.
