Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients must have been diagnosed with carcinoma of the breast and be a candidate for lymph node surgery as per each site's standard of care. The patients may be female or male, at least 18 years old, and must meet study inclusion criteria described later in this protocol. Patients receiving pre-operative therapy for breast cancer, such as neoadjuvant therapy and/or hormonal intervention are not eligible to participate in this study.

Who may be able to join

  • Pre-operatively established diagnosis of invasive carcinoma of the breast
  • Scheduled for axillary sentinel lymph node dissection as per standard of care at the clinical site for newly diagnosed breast cancer patients
  • Patients for whom the GeneSearch™ BLN Assay will be used intra-operatively to make a decision for an axillary lymph node dissection
  • 18 years of age or older
  • Female or male
  • Willing and able to give informed consent to participate in the study

Who cannot join

  • Previous diagnosis of lymphoma
  • Subjects participating in other research studies that would interfere with their full participation in this study
  • Patients and/or conditions with 'interfering substances' as listed in the IFU.
  • Patients who have had any pre-operative treatment for breast cancer including neoadjuvant and/or hormonal intervention such as aromatase inhibitors or tamoxifen

About this study

This post-approval study is designed to determine the performance of the FDA-approved GeneSearch™ BLN Assay when compared to the site's standard of care permanent section histological evaluation, and when compared to more extensive histological evaluation when the assay is being used by clinicians to make surgical decisions on complete axillary dissections (ALND).

Read the detailed description

The primary objective of this clinical study is to gather data to estimate the positive predictive concordance (PPC) between the GeneSearch™ BLN Assay and histology as routinely practiced, i.e., routine H\&E histology of sentinel lymph node(s) (SLN) and, when available, routine histology of non-sentinel axillary lymph nodes (ALN). This study will provide information on the assay that will augment the performance data gained in pre-market validation studies. In addition, with the assay being used for ALND decision-making, the metastatic status of the non-sentinel axillary nodes can be taken into account in the performance measures, i.e., if the patient's sentinel or non-sentinel nodes are histologically positive, the patient will be considered positive for the primary comparison to the assay results.

  • GeneSearch™ Breast Lymph Node (BLN) AssayDevice

    Also called BLN Assay, GeneSearch™ BLN Assay

    The GeneSearch™ BLN Assay is a real time Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) assay that detects the presence of breast tumor cell metastasis in lymph nodes through the detection of gene expression markers present in breast tissue, but not in nodal tissue (cell type specific messenger RNA).

What is being measured

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

  1. To estimate the positive predictive concordance (PPC) between the GeneSearch™ BLN Assay and histology as routinely practiced.

    Measured: 1 week

Secondary outcomes (2)
  1. To estimate the positive predictive value (PPV) of the GeneSearch™ BLN Assay as measured against histology that is as accurate as possible in assessing whether a SLN is truly positive.

    Measured: 1 week

  2. To gather data on size of metastases (micrometastases versus macrometastases) identified by histology to examine the assay performance for various levels of metastases.

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Janssen Diagnostics, LLC at 6 sites 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 6 inclusion and 4 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: stopped early, as of the sponsor's last update on 12 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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 was stopped early (reason given: GeneSearch™ BLN Assay has been voluntarily withdrawn from the US market.). 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?

To estimate the positive predictive concordance (PPC) between the GeneSearch™ BLN Assay and histology as routinely practiced. (time frame: 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00595296, which also lists 3 linked publications.

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 12 Jan 2016.
