GeneSearch™ Breast Lymph Node (BLN) Assay Post Approval Study

January 11, 2016 updated by: Janssen Diagnostics, LLC
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).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

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.

Description

Inclusion Criteria:

  • 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

Exclusion Criteria:

  • 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

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

All eligible patients.
Device: GeneSearch™ Breast Lymph Node (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).
Other Names:
  • BLN Assay

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To estimate the positive predictive concordance (PPC) between the GeneSearch™ BLN Assay and histology as routinely practiced.
Time Frame: 1 week
1 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
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.
Time Frame: 1 week
1 week
To gather data on size of metastases (micrometastases versus macrometastases) identified by histology to examine the assay performance for various levels of metastases.
Time Frame: 1 week
1 week
