PREDATOR: Neoadjuvant Gene Prediction for Breast Cancer

January 13, 2023 updated by: Jenny C. Chang, MD

Prospective Study To Validate The Predictive Value Of Mammostrat Score, DDR Score And TLE3 Gene When A Taxane-Based Chemo Agents Or Anthracycline-Based Chemo Agent Is Used In The Neo-Adjuvant Setting

Study of the assay, Mammostrat®. to verify its utility as a predictor or outcome tool to determine whom would benefit from chemotherapy prior to surgery. Also could be used as a clinical marker to identify patients with breast cancer who do not benefit from some preoperative chemotherapies.

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 purpose of this phase II study is to find out if the test, Mammostrat® can be used as a predictor or outcome tool to determine who will best benefit from chemotherapy prior to surgery. This can be used to determine if Mammostrat assay may be used as a clinical marker to identify a subset of women with breast cancer who do not benefit from preoperative chemotherapy, either taxane/taxane-like (T) chemo agents or anthracycline-based chemotherapy and cyclophosphamide (AC).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Description

Inclusion Criteria:

  1. Patients with histologic confirmation of invasive breast carcinoma.
  2. Patients must have intact primary tumor.
  3. ≥18 years of age.
  4. Patients with bilateral breast cancer are eligible.
  5. Patients with second primary breast cancers are eligible.
  6. The primary breast tumor must be ≥ 2 cm by physical exam or imaging.

  7. The tumor must have been determined to be HER2-negative as follows:

    • Fluorescent in situ hybridization (FISH)-negative (defined by ratio of HER2 to CEP17 must be < 2.2)
    • Immunohistochemistry (IHC) 0-1+; or
    • IHC 2+ and FISH-negative
  8. ECOG PS of 0, 1, or 2.
  9. Negative serum pregnancy test ≤7 days of treatment initiation and a serum or urine pregnancy test must be repeated ≤ 3 days prior to starting treatment for women of childbearing potential (WOCBP). For WOCBP, adequate contraception must be used throughout the study. For this study, acceptable methods of contraception include a reliable intrauterine device or a spermicide in combination with a barrier method. Women who are already on hormonal forms of birth control may continue that treatment but must also use a barrier method.
  10. Ability to understand the requirements of the study, provide written informed consent and authorization of use and disclosure of protected health information, and agree to abide by the study restrictions and return for the required assessments.
  11. Patient must be willing to undergo breast biopsies as required by the study protocol.
  12. Sufficient tissue must be available from the diagnostic core biopsies. If not, patients must undergo additional biopsies to perform Mammostrat.

Exclusion Criteria:

  1. Patients with a history of other invasive malignancies diagnosed and treated within the previous 5 years, except non-melanoma skin cancer and non-invasive cervical cancer.
  2. Prior treatment with any investigational drug within the preceding 4 weeks.
  3. Evidence of New York Heart Association class III or greater cardiac disease.
  4. History of myocardial infarction, stroke, ventricular arrhythmia, or symptomatic conduction abnormality within 6 months.
  5. Concurrent severe or uncontrolled medical disease (i.e., active systemic infection, diabetes, hypertension, coronary artery disease, congestive heart Failure or major surgery) that, in the opinion of the Investigator, would compromise the safety of the patient or compromise the ability of the patient to complete the study.
  6. Pregnant or nursing women.
  7. Known allergic reaction to Cremophor or any of the chemo agents on this trial.

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
Measure Description
Time Frame
Compare Mammostrat score clinical response rates to chemotherapy
Time Frame: 2 years
The percentage of patients undergoing chemotherapy who have Mammostrat low risk scores will be calculated
2 years

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
Measure Description
Time Frame
pathological complete response rate compare to predictors
