    Trial Purpose

    This research study is studying a combination of drugs as a possible treatment for breast
    cancer that has tested positive for a protein called HER2.

    The names of the study interventions involved in this study are:

    - Trastuzumab emtansine (also called T-DM1)

    - Pertuzumab

    Detailed Description

    This research study is a Phase II clinical trial. Phase II clinical trials test the safety
    and effectiveness of an investigational intervention to learn whether the intervention works
    in treating a specific disease. "Investigational" means that the intervention is being
    studied. The FDA (the U.S. Food and Drug Administration) has not approved T-DM1 for
    pre-operative use in breast cancer but it has been approved for other uses in breast cancer.
    The FDA has approved pertuzumab as a pre-operative treatment.

    Trial Arms

    Name Type Description Interventions
    T-DM1 and Pertuzumab Experimental T-DM1 via IV every 3 weeks for 6 doses and Pertuzumab loading dose via IV on Cycle 1 Day 1 followed by maintenance dose via IV every 3 weeks for 6 doses. Excision of tumor/mastectomy of biopsy residual tumor T-DM1, Pertuzumab

    Eligibility Criteria

    Inclusion Criteria:

    - Patients must have HER2-positive Stage II or III histologically confirmed invasive
    carcinoma of the breast. A minimum tumor size of 2 cm determined by physical exam or
    imaging is required.

    - HER-2 positive, confirmed by central testing (Clarient labs): IHC 3+ and/or FISH
    positive based on one of the three following criteria:

    - Single-probe average HER2 copy number6.0 signals/cell OR

    - Dual-probe HER2/CEP17 <2.0 with an average HER2 copy number 6.0 signals/cell OR

    - Dual-probe HER2/CEP17 ratio 2.0

    - ER/PR determination is required.

    - Bilateral breast cancers are allowed if both cancers are HER2-positive.

    - Patients with multifocal or multicentric disease are eligible as long as one area
    meets eligibility criteria.

    - Breast imaging should include the ipsilateral axilla. For subjects with a clinically
    negative axilla, a sentinel lymph node biopsy will be performed either before or
    after preoperative therapy at the discretion of the subject's physicians. For
    subjects with a clinically positive axilla, a needle aspiration, core biopsy or SLN
    procedure will be performed to determine the presence of metastatic disease in the
    lymph nodes.

    - Men and women (with any menopausal status) 18 years of age

    - ECOG performance status 0 or 1

    - Required laboratory values:

    - ANC 1500/mm3

    - Hemoglobin 9 g/dl

    - Platelets 100,000/mm3

    - Serum creatinine < 1.5 X ULN (institutional)

    - Total bilirubin 1.0 X ULN (institutional) For patients with Gilbert syndrome,
    the direct bilirubin should be within the institutional normal range.

    - AST and ALT 1.5x ULN (institutional)

    - Alkaline phosphatase 1.5x ULN (institutional)

    - Documentation of hepatitis B virus (HBV) and hepatitis C virus (HCV) serologies is
    required: this includes hepatitis B surface antigen (HBsAg) and/or total hepatitis B
    core antibody (HBcAb) in addition to HCV antibody testing.

    - Only for patients who test positive for hep B/C virus: PTT/INR < ULN (institutional)

    - Left ventricular ejection fraction (LVEF) 55%

    - Premenopausal women must have a negative serum pregnancy test, including women who
    have had a tubal ligation and for women less than 12 months after the onset of

    - Women of childbearing potential and men with partners of childbearing potential must
    be willing to use one highly effective form of non-hormonal contraception or two
    effective forms of non-hormonal contraception by the patient and/or partner and
    continue its use for the duration of the study treatment and for 7 months after the
    last dose of study treatment.

    - Potent CYP3A4 inhibitors, such as ketoconazole and erythromycin, should be avoided
    during the study treatment period with T-DM1.

    - Excessive alcohol intake should be avoided (occasional use is permitted).

    - Patients with a history of ipsilateral DCIS are eligible.

    - Patients undergoing breast conservation therapy (i.e. lumpectomy) must not have any
    contraindications to radiation therapy.

    - Willing and able to sign informed consent.

    - Willing to provide tissue for research purposes.

    Exclusion Criteria:

    - Pregnant or nursing women due to the teratogenic potential of the study drugs.

    - Active, unresolved infection.

    - Receipt of intravenous antibiotics for infection within 7 days prior to enrollment.

    - Patients with active liver disease, for example, due to hepatitis B virus, hepatitis
    C virus, autoimmune hepatic disorder, or sclerosing cholangitis.

    - Uncontrolled hypertension (systolic >180 mm Hg and/or diastolic >100 mm Hg) or
    clinically significant (i.e. active) cardiovascular disease: cerebrovascular
    accident/stroke or myocardial infarction within 6 months prior to first study
    medication, unstable angina, congestive heart failure (CHF) of New York Heart
    Association (NYHA) Grade II or higher, or serious cardiac arrhythmia requiring

    - Significant symptoms (Grade 2) peripheral neuropathy.

    - Other concurrent serious diseases that may interfere with planned treatment,
    including severe pulmonary conditions/illness, uncontrolled infections, uncontrolled

    - Any prior treatment for the current breast cancer, including chemotherapy, hormonal
    therapy, radiation or experimental therapy.
