Brief Summary:
The purpose of this research is to look at the safety and effectiveness of a HER2-targeted therapy neratinib when given with capecitabine, a chemotherapy, for breast cancer patients with brain metastases whose tumors were HER2-negative by standard tests but showed abnormal HER2 activity based on the CELsignia results.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Capecitabine and Neratinib. Phase 2

Detailed Description:

The purpose of this research is to look at the safety and effectiveness of a HER2-targeted therapy neratinib when given with capecitabine, a chemotherapy, for breast cancer patients with brain metastases whose tumors were HER2-negative by standard tests but showed abnormal HER2 activity based on the CELsignia results. The CELsignia test results might predict whether this breast cancer type will respond to treatment with neratinib and capecitabine.

Neratinib is called a HER2-targeted therapy because it stops cancer cells from growing by targeting and blocking the HER2 proteins that help cancer cells grow. Neratinib is an oral drug approved by the U.S. Food and Drug Administration (FDA) to treat HER2-positive breast cancer. It is considered investigational in this study because your breast cancer was determined to be HER2-negative by the standard method of testing. However, the CELsignia test showed that your breast cancer cells have HER2 pathway activity that might respond to HER2-targeted treatment.

Primary Outcome Measures :
  1. overall survival [ Time Frame: 24 months ]
    The study will assess how long participants with HER2 negative metastatic breast cancer with brain metastasis and abnormal HER2 signalling will survive if treated with capecitabine and neratinib

  2. CNS progression free survival [ Time Frame: 24 months ]
    The study will assess how long participants with HER2 negative metastatic breast cancer with brain metastasis and abnormal HER2 signalling will survive and also not have the cancer get worse in the brain while treated with capecitabine and neratinib

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects must meet all of the following criteria to be enrolled:

    • Male/Female
    • At least 18 years of age
    • Histologically confirmed HER2 negative breast cancer determined from the most recent tumor sample (primary or metastatic), as per the current American Society of Clinical Oncology and College of American Pathologists HER2 testing guidelines.
    • For ER positive breast cancer patients: prior treatment with a CDK4/6 inhibitor and endocrine therapy in required in the metastatic settings. If a patient has received a CDK4/6 inhibitor plus endocrine therapy in the adjuvant settings and the cancer recurred while on the CDK4/6 inhibitor or within 12 months of the end of CDK4/6 inhibitor treatment, then the patient will eligible without getting a CDK4/6 inhibitor and endocrine therapy in the metastatic setting.
    • For triple negative breast cancer patients: no specific prior anti-cancer treatment is required.
    • Have radiological evidence of one or more brain metastases.
    • Ability to obtain an MRI.
    • Has a radiological evidence of a measurable disease (per RECIST 1.1) outside of the brain which is accessible to a biopsy
    • Willing to undergo a research core biopsy of the tumor tissue
    • Considered to be medically fit for undergoing a biopsy
    • Subjects anticipated by the investigator to be a candidate for systemic therapy immediately or in the future.
    • Ability to understand the investigational nature of the study and sign the informed consent
  • Key Criteria for Step 1 Registration:

    • Abnormally active HER2 signaling as determined by the CELsignia test on the tumor tissue.
    • New or progressive brain metastases defined as any one of the following:
    • Untreated measurable lesions in patients who have received surgery and/or stereotactic radiosurgery (SRS) to one or more other lesions.
    • Residual or progressive lesions after surgery if asymptomatic.
    • Patients who have had prior whole-brain radiotherapy (WBRT) and/or SRS and then whose lesions have progressed by RANO-BM criteria or there are new lesions are eligible. Lesions treated with SRS may be eligible if there is unequivocal evidence of progression.
    • Patients who have not previously been treated with cranial radiation (e.g., WBRT or SRS) are eligible, but such patients must be asymptomatic and neurologically stable from their CNS metastases.
    • Measurable brain metastases with at least one lesion > 5 mm in longest diameter AND is/are new or progressive lesion/s as defined by criterion B.
    • Ability to obtain MRI
    • No major surgery within 10 days prior to registration. Surgeries should be avoided any time after registration during the study treatment, but minor procedures like dental extractions and surgeries deemed important to maintain or improve patients' quality of life and are allowed.
    • A minimum of 14 days since the last dose of chemotherapy except for the optional pre-Step 1 capecitabine. If pre-step 1 optional capecitabine was administered, then a minimum of 7 days from the last dose of Capecitabine is required before registration. There is no limit on the number of previous chemotherapy regimens for eligibility.
    • A minimum of 7 days since the last dose of any hormonal therapy (no limit on the number of previous hormonal regimens for eligibility) except fulvestrant. A minimum of 28 days since the last dose of fulvestrant before registration.
