Trial summary

This research trial studies tumor samples from patients with ependymoma treated on the Children Oncology Group ACNS0121 trial. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

About this study

Official title: Examination of the Multiple Genetic and Molecular Targets as Therapeutic Options for Patients With Ependymoma Treated by the Phase II Children's Oncology Group Study ACNS0121

This research trial studies tumor samples from patients with ependymoma treated on the Children Oncology Group ACNS0121 trial. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors find better ways to treat cancer.

PRIMARY OBJECTIVES:

  1. To examine the prognostic role of histopathological variables, in particular cellular density, mitotic count, and tumor cell invasion in intracranial pediatric ependymomas.

II. To study whether hTERT expression and telomere dysfunction correlate with progression-free survival (PFS) and overall survival (OS) in pediatric intracranial ependymoma.

III. To perform a genome-wide copy number screen and validation of copy number abnormalities (CNAs) on formalin-fixed paraffin-embedded (FFPE) ependymomas using Affymetrix Molecular Inversion Probe (MIP) arrays and interphase fluorescence in situ hybridization (iFISH). IV. To evaluate associations between infiltration of immune markers and PFS as well as OS in pediatric ependymoma.

  1. To examine the role of 1q gain and 9p deletion in pediatric ependymomas by exploring their association with PFS and OS in a multivariable model.

VI. To establish the frequency and clinicopathological associations of mutations in genes involved in Notch pathway signaling.

OUTLINE:

Archived tumor tissue samples are analyzed for cellular density, mitotic count, tumor cell invasion, hTERT expression, telomere dysfunction, 1q gain, 9p deletion, and genetic mutations by IHC, Affymetrix Molecular Inversion Probe (MIP) arrays, and fluorescence in situ hybridization (FISH). Results are then correlated with patient-outcome variables and known risk factors, namely gender, age at diagnosis, tumor location infratentorial vs. supratentorial), tumor grade (differentiated vs anaplastic), and extent of surgery as well as pathologic variables.

What is being measured

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

  1. PFS

    The multivariable Cox model and cumulative incidence regression models will be used. Associations between the biology markers and outcome variables will be studied in a single-variable setting as well as via multivariable Cox models.

    Measured: From the time of study enrollment to disease progression, disease relapse or death from any cause

  2. OS

    The multivariable Cox model and cumulative incidence regression models will be used. Associations between the biology markers and outcome variables will be studied in a single-variable setting as well as via multivariable Cox models.

    Measured: From the time of study enrollment to death from any cause

Questions about this trial

What is this clinical trial studying?

An observational study of Childhood Infratentorial Ependymoma and Childhood Supratentorial Ependymoma, 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 2 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 18 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?

PFS (time frame: From the time of study enrollment to disease progression, disease relapse or death from any cause). 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?
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 18 May 2016.
