WOKVAC: Vaccine Therapy in Preventing Cancer Recurrence in Patients With Non-Metastatic, Node Positive, HER2 Negative Breast Cancer That is in Remission
Study Details
Study Description
Brief Summary
This phase I trial studies the side effects and best dose of a vaccine therapy in preventing cancer from coming back in patients with non-metastatic, node positive, human epidermal growth factor receptor (HER)2 negative breast cancer in which all signs and symptoms have disappeared. Vaccines made from deoxyribonucleic acid (DNA) may help the body build an effective immune response to kill tumor cells. Giving multiple vaccinations may make a stronger immune response and prevent or delay the return of cancer.

Phase 1 |
Detailed Description
PRIMARY OBJECTIVES:
- To assess the safety of 3 escalating doses of a deoxyribonucleic acid (DNA) plasmid based vaccine encoding three breast cancer antigens (insulin-like growth factor-binding protein [IGFBP]-2, HER2, and insulin-like growth factor [IGF]-1 receptor [1R]) in patients with breast cancer.
SECONDARY OBJECTIVES:
-
To determine the immunogenicity of pUMVC3-IGFBP2-HER2-IGF1R (WOKVAC) T helper cells (Th) polyepitope plasmid based vaccine in patients with breast cancer at 3 escalating doses.
-
To determine whether a WOKVAC Th polyepitope plasmid based vaccine elicits a persistent memory T cell response.
-
To evaluate whether WOKVAC vaccination modulates T regulatory cells (Treg) and myeloid derived suppressor cells (MDSC).
-
To evaluate changes in mammographic density using clinically available images prior to baseline and post vaccination as an exploratory analysis.
-
To determine a recommended phase 2 WOKVAC dose for further breast cancer prevention studies.
OUTLINE: This is a dose escalation study of WOKVAC.
Patients receive WOKVAC with sargramostim intradermally (ID) on day 1. Courses repeat every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.
Patients with axillary lymph node dissection (ALND) will have vaccine administered to the contralateral arm. Patients with bilateral ALND will have vaccine administered in the thigh. As much as possible each vaccine dose will be given within the same draining lymph node site. Patients will be monitored for a minimum of 60 minutes post vaccine administration.
After completion of study treatment, patients are followed up at 1 month, 6 months and annually for up to 5 years thereafter.

Outcome Measures
Primary Outcome Measures
- Incidence of toxicity assessed by adverse events per Common Terminology Criteria for Adverse Events version 4.0 [Up to 5 years]
Type and grade of toxicities noted during the immunization regimen will be summarized. Duration of toxicities will also be summarized using descriptive statistics such as mean and standard deviation. The frequency and severity of adverse events will be summarized with a proportion and a 95% confidence interval.
Secondary Outcome Measures
- Assessment of IgG antibodies [Up to 4 months]
Immune response will be measured by indirect enzyme-linked immunosorbent assay and serum antibody avidity to determine an avidity index before and after vaccination. Patients will be considered to have developed an antibody response if antigen specific IgG antibodies are both detectable and have moderate to high avidity.
- Assessment of T helper Th1:Th2 ratio [Up to 4 months]
IFN-g (Th1) and IL-10 (Th2) T-cells will be evaluated using enzyme-linked immunosorbent spot assay. Patients will be considered to have developed a Th1 immune response if the ratio of magnitude of Th1 (IFN-gamma)/Th2 (IL-10) is >1.
- Assessment of the immunogenicity of WOKVAC by generation of IGFBP-2, HER2, and IGF-1R specific type 1 (Th1) T- cells [Up to 4 months]
Immune responses will be measured by IFN-g enzyme-linked immunosorbent spot assay and summarized with mean and standard deviation. Each patient will be given a value at each immune evaluation that is the sum of the median response to HER2, IGFBP-2 or IGF1R, and a composite median would be calculated for each WOKVAC dose level. Patients will be considered to have generated antigen specific (IGFBP-2, HER2, and IGF-1R) Th1 T-cells if they have a ≥1:20,000 composite mean IFN-gamma (IFN-g) precursor frequency by IFN-g enzyme-linked immunosorbent spot assay or greater than 2 fold increase over basel
- Level of antigen specific central and effector memory phenotypes (Persistent memory T cell response) [Up to 6 months after the last vaccine]
Assessed by flow cytometry of peripheral blood mononuclear cells using an established T-cell activation panel and summarized with mean and standard deviation or median and range over time.
- Modulation of myeloid derived suppressor cell levels [Up to 6 months after the last vaccine]
Assessed by flow cytometry of peripheral blood mononuclear cells using an established myeloid derived suppressor cell/ regulatory T-cell panel and summarized with mean and standard deviation or median and range over time.
- Modulation of T regulatory cell levels [Up to 6 months after the last vaccine]
Assessed by flow cytometry of peripheral blood mononuclear cells using an established myeloid derived suppressor cell/ regulatory T-cell panel and summarized with mean and standard deviation or median and range over time.
Other Outcome Measures
- Change in mammographic density assessed using clinically available images and the automated Cumulus software program [Up to 6 months after the last vaccine]
Summarized with mean and standard deviation or median and range at pre- and post-vaccination in tabular and graphical formats, along with the change from pre- to post-vaccination in a similar manner by dose level.
