About

This phase II trial studies the immunologic response and side effects of using the WOKVAC vaccine in combination with chemotherapy and HER2-targeted monoclonal antibody therapy before surgery in treating patients with breast cancer. Vaccines like WOKVAC are made from tumor-associated antigens which may help the body build an effective immune response to kill tumor cells. Chemotherapy drugs, such as paclitaxel, 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. Trastuzumab and pertuzumab are forms of targeted therapy because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When trastuzumab and pertuzumab attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving the WOKVAC vaccine at the same time (concurrently) with paclitaxel, trastuzumab, and pertuzumab before surgery may kill more tumor cells.

Full description

OUTLINE:

Patients receive WOKVAC intradermally (ID) on day 13. Treatment repeats for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive paclitaxel via infusion on days 1, 8, and 15 or docetaxel intravenously (IV) and carboplatin IV on day 1, and trastuzumab IV and pertuzumab IV on day 1. The chemo and trastuzumab and pertuzumab will most likely be given by the patient's own oncologist per standard of care. Treatment repeats for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo ultrasound imaging or magnetic resonance imaging and biopsy on study and blood sample collection throughout the study.

After completion of study treatment, patients are followed up annually for up to 5 years from enrollment.

Patients who have received prior neoadjuvant chemotherapy are allowed but may only receive paclitaxel, trastuzumab, and pertuzumab for the duration the study
Subjects with Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
White blood cell (WBC) >= 3000/mm^3 (within 4 weeks of initiating study treatment)
Lymphocyte count >= 500/mm^3 (within 4 weeks of initiating study treatment)
Absolute neutrophil count (ANC) >= 1,500/ uL (within 4 weeks of initiating study treatment)
Platelets >= 75,000/ uL (within 4 weeks of initiating study treatment)
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN), except patients with Gilbert's syndrome in whom total bilirubin must be < 3.0 mg/dL (within 4 weeks of initiating study treatment)
Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3 x institutional upper limit of normal (ULN) (within 4 weeks of initiating study treatment)

Female patients of child-bearing potential must agree to use dual methods of contraception and have a negative urine pregnancy test at screening, and male patients must use an effective barrier method of contraception if sexually active with a female of child-bearing potential. Acceptable methods of contraception are condoms with contraceptive foam, oral, implantable or injectable contraceptives, contraceptive patch, intrauterine device, diaphragm with spermicidal gel, or a sexual partner who is surgically sterilized or post-menopausal. For both male and female patients, effective methods of contraception must be used throughout the study and for three months following the last vaccine
