Trial summary

RATIONALE: Studying samples of blood and 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 predict how well patients will respond to treatment. Read more about this study

About this study

Official title: Validating the Predictive Value (of Response to Rituximab Induction and Maintenance) of the FCGR3A 158V/F Polymorphism Using Complimentary Genotyping Methods

RATIONALE: Studying samples of blood and 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 predict how well patients will respond to treatment.

PURPOSE: This research study is studying biomarkers in predicting response to rituximab treatment in samples from patients with indolent follicular lymphoma.

Read the detailed description

OBJECTIVES:

Primary

  • Genotype the full cohort of samples available from the RESORT clinical trial (ECOG-E4402) for FCGR3A 158V/F in parallel to independently verify results.
  • Correlate the FCGR3A 158V/F polymorphisms to response, response duration, and time to rituximab resistance.

Secondary

  • Quantify copy number variation in FCGR3A in this cohort.

OUTLINE: Archived DNA samples isolate from peripheral blood mononuclear cells and from formalin-fixed paraffin-embedded tissue samples are analyzed for FCGR3A 158V/F polymorphisms using different complementary genotyping methods. Assay results are reviewed and compared with patients' outcome data.

Questions about this trial

What is this clinical trial studying?

An observational study of Lymphoma, run by ECOG-ACRIN Cancer Research Group.

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 2017. 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?

Correlation of FCGR3A 158V/F polymorphisms with response, duration of response, and time to rituximab resistance (time frame: 1 year). 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 2017.
