What is the purpose of this trial?

This randomized phase III trial studies docetaxel, carboplatin, trastuzumab, and pertuzumab with estrogen deprivation to see how they work compared to docetaxel, carboplatin, trastuzumab, and pertuzumab without estrogen deprivation in treating patients with hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-positive breast cancer that is operable or has spread from where it started to nearby tissue or lymph nodes (locally advanced). Drugs used in chemotherapy, such as docetaxel, carboplatin, trastuzumab, and pertuzumab, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Estrogen can cause the growth of breast cancer cells. Hormone therapy using goserelin acetate and aromatase inhibition therapy may fight breast cancer by blocking the use of estrogen by the tumor cells. Radiation therapy uses high energy x rays to kill tumor cells. Giving combination chemotherapy and radiation therapy with or without hormone therapy may be an effective treatment for hormone receptor-positive, HER2-positive, operable or locally advanced breast cancer.

Date & Status


Who can Participate?


18 and older



Inclusion Criteria:

- Patients should have a life expectancy of at least 10 years, excluding their
diagnosis of breast cancer; (comorbid conditions should be taken into consideration,
but not the diagnosis of breast cancer)

- Women of reproductive potential must agree to use an effective non-hormonal method of
contraception during study therapy (chemotherapy, trastuzumab, pertuzumab, and
estrogen deprivation therapy) and for at least 7 months after the last dose of study

- Submission of tumor samples is required for all patients; the local pathology
department policy regarding release of tumor samples must be considered in the
screening process; patients whose tumor samples are located in a pathology department
that by policy will not submit any samples for research purposes should not be
approached for participation in the B-52 trial

- The patient must have signed and dated an Institutional Review Board (IRB)-approved
consent form that conforms to federal and institutional guidelines

- The patient must have an Eastern Cooperative Oncology Group (ECOG) performance status
of 0 or 1

- Clinical staging for the primary tumor can be cT1c (must be 2.0 cm) or T2-T4 if
clinically node negative; if the regional lymph nodes are cN1 and cytologically or
histologically positive or if cN2-N3 with or without a biopsy, the primary breast
tumor can be cT0-T4

- The diagnosis of invasive adenocarcinoma of the breast must have been made by core
needle biopsy

- Ipsilateral axillary lymph nodes must be evaluated by imaging (mammogram, ultrasound,
and/or magnetic resonance imaging [MRI]) within 6 weeks prior to randomization; if
suspicious or abnormal, fine needle aspirate (FNA) or core biopsy is recommended,
also within 6 weeks prior to randomization; findings of these evaluations will be
used to determine the nodal status prior to randomization:

- 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

- Patients may be premenopausal or postmenopausal at the time of randomization; for
study purposes, postmenopausal is defined as:

- Age 56 or older with no spontaneous menses for at least 12 months prior to study
entry; or

- Age 55 or younger with no spontaneous menses for at least 12 months prior to
study entry (e.g., spontaneous or secondary to hysterectomy) and with a
documented estradiol level in the postmenopausal range according to local
institutional/laboratory standard; or

- Documented bilateral oophorectomy

- The tumor must have been determined to be HER2-postive as follows:

- Immunohistochemistry (IHC) 3+ or

- In situ hybridization (ISH)-positive (defined by ratio of HER2 to circulating
endothelial progenitors [CEP]17 >= 2.0 or HER2 gene copy number >= 6 per

- The tumor must have been determined to be estrogen receptor (ER) and/or progesterone
(PgR) positive assessed by current American Society of Clinical Oncology
(ASCO)/College of American Pathologist (CAP) guideline recommendations for hormone
receptor testing; patients with >= 1% ER or PgR staining by IHC are considered

- Absolute neutrophil count (ANC) must be >= 1200/mm^3

- Platelet count must be >= 100,000/mm^3

- Hemoglobin must be >= 10 g/dL

- Total bilirubin must be =< upper limit of normal (ULN) for the lab unless the patient
has a bilirubin elevation > ULN to 1.5 x ULN due to Gilbert's disease or similar
syndrome involving slow conjugation of bilirubin

- Alkaline phosphatase must be =< 2.5 x ULN for the lab

- Aspartate aminotransferase (AST) must be =< 1.5 x ULN for the lab

- Alkaline phosphatase and AST may not both be > the ULN; for example, if the alkaline
phosphatase is > the ULN but =< 2.5 x ULN, the AST must be =< the ULN; if the AST is
> the ULN but =< 1.5 x ULN, the alkaline phosphatase must be =< ULN; Note: If alanine
aminotransferase (ALT) is performed instead of AST (per institution's standard
practice), the ALT value must be =< 1.5 x ULN; if both were performed, the AST must
be =< 1.5 x ULN

- Patients with AST or alkaline phosphatase > ULN are eligible for inclusion in the
study if liver imaging (computed tomography [CT], MRI, positron emission tomography
[PET]-CT, or PET scan) performed within 6 weeks prior to randomization does not
demonstrate metastatic disease and the requirements are met

- Patients with alkaline phosphatase that is > ULN but =< 2.5 x ULN or unexplained bone
pain are eligible for inclusion in the study if a bone scan, PET-CT scan, or PET scan
performed within 6 weeks prior to randomization does not demonstrate metastatic

- Within 6 weeks prior to randomization, the most recent serum creatinine must be =<
ULN or measured or calculated creatinine clearance must be > 60 mL/min

- Left ventricular ejection fraction (LVEF) assessment must be performed within 90 days
prior to randomization; (LVEF assessment performed by 2-dimensional [2-D]
echocardiogram is preferred; however, multi gated acquisition scan [MUGA] scan may be
substituted based on institutional preferences); the LVEF must be >= 50% regardless
of the cardiac imaging facility's lower limit of normal; note: since the pre-entry
LVEF serves as the baseline for comparing subsequent LVEF assessments, it is critical
that this baseline study be an accurate assessment; if the baseline LVEF is > 65%,
the investigator is encouraged to have the accuracy of the initial LVEF result
confirmed and repeat the test if the accuracy is uncertain
