Study of Neoadjuvant Chemotherapy Plus Trastuzumab and Pertuzumab in HER2-Negative Breast Cancer Patients With Abnormal HER2 Signaling

Status unconfirmed · Phase 2

Conditions studied: HER2-negative Breast Cancer

In brief

This is a prospective, single arm, open label, multicenter interventional study designed to evaluate the efficacy of neoadjuvant chemotherapy with anti-HER2 antibodies in patients with HER2-negative invasive breast cancer who have abnormal HER2 signaling activity determined by the Celcuity CELx HER2 Signaling Function (HSF) testing.

You may qualify if…

• SCREENING PRIOR TO INITIATING CHEMOTHERAPY
• Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 The diagnosis of invasive adenocarcinoma of the breast must have been made by core needle biopsy.
• The primary breast tumor must be palpable and measure greater than or equal 2.0 cm on physical exam.
• The regional lymph nodes can be cN0, cN1, or cN2a.
• Histological grade II or III tumor.
• Ipsilateral axillary lymph nodes must be evaluated by imaging (mammogram, ultrasound, and/or MRI) within 6 weeks prior to initiating chemotherapy. If suspicious or abnormal, FNA or core biopsy is recommended, also within 6 weeks prior to initiating chemotherapy. Findings of these evaluations will be used to determine the nodal status prior to initiating chemotherapy.
• Nodal status - negative: Imaging of the axilla is negative; Imaging is suspicious or abnormal but the FNA or core biopsy of the questionable node(s) on imaging is negative;
• Nodal status - positive: FNA or core biopsy of the node(s) is cytologically or histologically suspicious or positive. Imaging is suspicious or abnormal but FNA or core biopsy was not performed.
• Tumor specimen obtained at the time of diagnosis must have ER and progesterone receptor (PgR) analysis assessed by current ASCO/CAP Guidelines. Patients are eligible with either hormone receptor-positive or hormone receptor-negative tumors.
• Tumor specimen obtained at the time of diagnosis must have been determined to be HER2-negative as follows:
• Immunohistochemistry (IHC) 0-1+; or
• IHC 2+ and in situ hybridization (ISH) non-amplified with a ratio of HER2 to chromosome enumeration probe 17 (CEP17) less than 2.0, and if reported, average HER2 gene copy number less than 4 signals/cells; or
• ISH non-amplified with a ratio of HER2 to CEP17 less than 2.0, and if reported, average HER2 gene copy number less than 4 signals/cells.
• Blood counts performed within 6 weeks prior to initiating chemotherapy must meet the following criteria:
• absolute neutrophil count (ANC) must be greater than or equal 1200/mm3;
• platelet count must be greater than or equal 100,000/mm3; and
• hemoglobin must be greater than or equal 10 g/dL.
• The following criteria for evidence of adequate hepatic function performed within 6 weeks prior to initiating chemotherapy must be met:
• total bilirubin must be less than or equal to upper limit of normal (ULN) for the lab unless the patient has a bilirubin elevation greater than ULN to 1.5 x ULN due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and
• alkaline phosphatase must be less than or equal to 2.5 x ULN for the lab; and
• aspartate aminotransferase (AST) must be less than or equal to 1.5 x ULN for the lab.
• Alkaline phosphatase and AST may not both be greater than the ULN. For example, if the alkaline phosphatase is greater than the ULN but less than or equal to 2.5 x ULN, the AST must be less than or equal to the ULN. If the AST is greater than the ULN but less than or equal to 1.5 x ULN, the alkaline phosphatase must be less than or equal to ULN. Note: If alanine aminotransferase (ALT) is performed instead of AST (per institution's standard practice), the ALT value must be less than or equal to 1.5 x ULN; if both were performed, the AST must be less than or equal to 1.5 x ULN.
• Patients with AST or alkaline phosphatase greater than ULN are eligible for inclusion in the study if liver imaging (CT, MRI, PET-CT, or PET scan) performed within 6 weeks prior to initiating chemotherapy does not demonstrate metastatic disease and the requirements in next criteria are met.
• Patients with alkaline phosphatase that is greater than ULN but less than or equal to 2.5 x ULN or unexplained bone pain are eligible for inclusion in the study if a bone scan, PET-CT scan, or positron emission tomography (PET) scan performed within 6 weeks prior to initiating chemotherapy does not demonstrate metastatic disease.
• Serum creatinine performed within 6 weeks prior to initiating chemotherapy must be less than or equal to 1.5 x ULN for the lab.

You may not qualify if…

• T4 tumors including inflammatory breast cancer.
• FNA alone to diagnose the breast cancer.
• Excisional biopsy or lumpectomy performed prior to initiating chemotherapy.
• Surgical axillary staging procedure prior to initiating chemotherapy. Pre-neoadjuvant therapy sentinel node biopsy is not permitted. (FNA or core biopsy is acceptable.)
• Definitive clinical or radiologic evidence of metastatic disease. Required imaging studies must have been performed within 6 weeks prior to initiating chemotherapy.
• Synchronous bilateral invasive breast cancer. (Patients with synchronous and/or previous contralateral ductal carcinoma in situ [DCIS] or lobular carcinoma in situ [LCIS] are eligible.)
• Any previous history of ipsilateral invasive breast cancer or ipsilateral DCIS. (Patients with synchronous or previous ipsilateral LCIS are eligible.)
• Previous therapy with anthracycline, taxanes, trastuzumab, or other HER2 targeted therapies for any malignancy.
• Any sex hormonal therapy, e.g., birth control pills, ovarian hormone replacement therapy, etc. (These patients are eligible if this therapy is discontinued prior to initiating chemotherapy.)
• History of non-breast malignancies (except for in situ cancers treated only by local excision and basal cell and squamous cell carcinomas of the skin) within 2 years prior to initiating chemotherapy.
• Cardiac disease (history of and/or active disease) that would preclude the use of the drugs included in the treatment regimens. This includes but is not confined to:
• Active cardiac disease: angina pectoris that requires the use of anti-anginal medication; ventricular arrhythmias except for benign premature ventricular contractions; supraventricular and nodal arrhythmias requiring a pacemaker or not controlled with medication; conduction abnormality requiring a pacemaker; valvular disease with documented compromise in cardiac function; and symptomatic pericarditis.
• History of cardiac disease: myocardial infarction documented by elevated cardiac enzymes or persistent regional wall abnormalities on assessment of left ventricular (LV) function; history of documented congestive heart failure (CHF); and documented cardiomyopathy.
• Uncontrolled hypertension defined as sustained systolic BP greater than 150 mmHg or diastolic BP greater than 90 mmHg. (Patients with initial BP elevations are eligible prior to initiating chemotherapy if initiation or adjustment of BP medication lowers pressure.)
• Active hepatitis B or hepatitis C with abnormal liver function tests. Intrinsic lung disease resulting in dyspnea.
• Poorly controlled diabetes mellitus.
• Active infection or chronic infection requiring chronic suppressive antibiotics.
• Patients known to be HIV positive.
• Nervous system disorder (paresthesia, peripheral motor neuropathy, or peripheral sensory neuropathy) greater than or equal to grade 2, per the CTCAE v4.0.
• Malabsorption syndrome, ulcerative colitis, resection of the stomach or small bowel, or other disease significantly affecting gastrointestinal function.
• Other non-malignant systemic disease that would preclude treatment with any of the treatment regimens or would prevent required follow-up.
• Conditions that would prohibit administration of corticosteroids.
• Chronic daily treatment with corticosteroids with a dose of greater than or equal to 10 mg/day methylprednisolone equivalent (excluding inhaled steroids).
• Known hypersensitivity to any of the study drugs or any of the ingredients or excipients of these drugs (e.g., Cremophor EL), including sensitivity to benzyl alcohol.
• Pregnancy or lactation at the initiation of chemotherapy. (Note: Pregnancy testing must be performed within 2 weeks prior to initiating chemotherapy according to institutional standards for women of childbearing potential.)
