About this study

Official title: Estrogen-Related Receptor Alpha As A Novel Biomarker For Breast Cancer

RATIONALE: 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.

PURPOSE: This research study is looking at tissue samples from patients with breast cancer.

Read the detailed description

OBJECTIVES:

  • Identify by mass spectroscopy and site-specific mutagenesis the post-translational modifications of estrogen-related receptor alpha (ERRα1) that are responsible for ERRα1 function as a constitutive activator rather than a down-modulator of transcription of estrogen response element-regulated genes in tumors of patients with breast cancer.
  • Produce a panel of monoclonal antibodies to ERRα1 by standard hybridoma methods that can be used to distinguish between the activator and repressor forms of this receptor in these patients.
  • Validate the utility for immunohistochemistry (IHC) assays of some of the ERRα-specific sera by performing IHC and quantitative real-time PCR on some primary breast carcinomas.
  • Correlate the results of IHC studies on archival paraffin sections of primary breast tumors using monoclonal antibodies to ERRα1, ERRα1 status, currently assayed biomarkers, and course of treatment with patient outcomes.

OUTLINE: Breast tumor tissue samples are obtained from a tissue bank in the form of frozen tumors and paraffin-embedded sections on microarray blocks. Monoclonal antibodies (MOABs) to ERRα1 are produced using antigens in these tissue samples and immunohistochemical studies are performed using the MOABs. Cytogenetic studies are performed on DNA purified from these tissue samples.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

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

  1. Post-translational modifications of estrogen-related receptor alpha (ERRα1) that are responsible for ERRα1 function as a constitutive activator rather than a down-modulator of transcription of estrogen response element-regulated genes

  2. Production of a panel of monoclonal antibodies to ERRα1 by standard hybridoma methods that can be used to distinguish between the activator and repressor forms of this receptor

  3. Validation of the utility for immunohistochemistry (IHC) assays of some of the ERRα-specific sera by performing IHC and quantitative real-time PCR on some primary breast carcinomas

  4. Correlation of the results of IHC studies on archival paraffin sections of primary breast tumors using monoclonal antibodies to ERRα1, ERRα1 status, currently assayed biomarkers, and course of treatment with patient outcomes

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by University of Wisconsin, Madison.

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: status not confirmed, as of the sponsor's last update on 29 Feb 2016. 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?

Results are not available in the source record.

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?

Post-translational modifications of estrogen-related receptor alpha (ERRα1) that are responsible for ERRα1 function as a constitutive activator rather than a down-modulator of transcription of estrogen response element-regulated genes. 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 29 Feb 2016.
