Concurrent WOKVAC Vaccination, Chemotherapy, and HER2-Targeted Monoclonal Antibody Therapy Before Surgery for the Treatment of Patients With Breast Cancer
Study Details
Study Description
Brief Summary
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.
Detailed 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, and trastuzumab intravenously (IV) and pertuzumab IV on day 1. The chemo and trastuzumab and pertuzumab will most likely be given by their own oncologist per standard of care. Treatment repeats for up to 4 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up annually for up to 5 years from enrollment.

Outcome Measures
Primary Outcome Measures
- Enumeration of the number of T-bet+, CD4+, and CD8+ T-cells in tumor infiltrating lymphocytes (TIL) after combination immune-chemotherapy [Up to completion of surgical resection]
Tumor tissue will be collected from prior diagnostic tumor biopsies as well as from an ultrasound guided core needle biopsy performed on day 13 of cycle 3. Tumor biopsies collected pre- and post- trial therapy will be processed and evaluated by immunohistochemistry for differences and changes in T cell content and T cell subtype. Specifically, will evaluate the differences in the presence of T-bet+ CD4+ and CD8+ T cells, a T cell subtype recently recognized to influence both the induced human epidermal growth factor receptor 2 (HER2)-specific cellular immunity and clinical outcomes. Changes in the tumor content of T-bet+ CD4+ and CD8+ T cells between the pre- and post-trial therapy time points will be evaluated.
Secondary Outcome Measures
- Incidence of adverse events [Up to 5 years]
Safety will be assessed per Common Terminology Criteria for Adverse Events version (v)4.0. The type and grade of toxicities noted during the immunization regimen will be summarized. The duration of toxicities will also be summarized using descriptive statistics such as mean and standard deviation. All adverse events noted by the investigator will be tabulated according to the affected body system. The frequency and severity of adverse events will be summarized with a proportion and a 95% confidence interval.
- Induction of type 1 helper cell (Th1) immunity against HER2, IGF-1R, and IGFBP2 [Up to day 13 of cycle 4 (each cycle is 21 days)]
Cellular immune response will be defined by the magnitude of the Th1 (interferon-gamma [IFN-g]) versus (vs.) type 2 helper cell (Th2) (IL-10) antigen specific immune response using enzyme-linked immunosorbent spot assay (ELISPOT). Immune responses as measured by IFN-g ELISPOT will be summarized with mean and standard deviation or median and range over time, the change over time will be summarized with graphs, and also analyzed using linear mixed-effects regression models with normalizing transformation if necessary. The proportion of study participants who develop immunity to either of the three antigens will be computed and 95% confidence internal would be generated. The induction of Th1 immunity will be compared against the presence or absence of a complete pathologic response to determine if there is a significant correlation using Pearson r correlation analysis.
