About this study

Official title: Determination Of FEZ1/LZTS1 Expression As A Predictor Of Response To Taxol

RATIONALE: DNA analysis of tumor tissue may help doctors predict how patients who receive paclitaxel will respond to treatment.

PURPOSE: This laboratory study is evaluating gene expression in predicting response to paclitaxel in patients with breast cancer.

Read the detailed description

OBJECTIVES:

  • Determine whether loss of function of the FEZ1/LZTS1 gene is a predictor of response in patients with breast cancer treated with paclitaxel.

OUTLINE: This is a single-blind study.

Tumor tissue is analyzed for FEZ1/LZTS1 gene expression by immunohistochemistry using an antibody for the gene. Tumor expression of the gene is characterized by immunohistochemistry and scored by intensity of staining, percent of cell staining, and staining index. Tumor tissue is also analyzed for FEZ1/LZTS1 gene disruption by reverse transcriptase-polymerase chain reaction and direct sequencing.

PROJECTED ACCRUAL: Approximately 120 patients will be accrued for this study.

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. Evaluation of the association between tumor expression of FEZ1/LZTS1 gene and response to paclitaxel

Secondary outcomes (1)
  1. Utility of FEZ1/LZTS1 gene expression in predicting the full 4-level response pattern (complete response, partial response, stable disease, progressive disease)

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Thomas Jefferson University.

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 18 Dec 2013. 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?

Evaluation of the association between tumor expression of FEZ1/LZTS1 gene and response to paclitaxel. 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 Dec 2013.
