Concurrent WOKVAC Vaccination, Chemotherapy, and HER2-Targeted Monoclonal Antibody Therapy Before Surgery for the Treatment of Patients With Breast Cancer

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.
