Brief summary

This phase II trial studies how well pUMVC3-IGFBP2 plasmid deoxyribonucleic acid (DNA) vaccine (IGFBP-2 vaccine) and combination chemotherapy work in treating patients with stage III-IV ovarian, fallopian tube, or primary peritoneal cancer undergoing surgery. IGFBP-2 is a protein found in the blood and tumor cells of most who have been diagnosed with ovarian cancer. Too much IGFBP-2 has been associated with more invasive disease. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells that express IGFBP-2. Drugs used in chemotherapy, such as paclitaxel and carboplatin, 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. Giving IGFBP-2 vaccine and combination chemotherapy may work better in treating patients with stage III-IV ovarian, fallopian tube, or primary peritoneal cancer undergoing surgery.

Detailed description

PRIMARY OBJECTIVES: I. Determine whether the addition of an IGFBP-2 vaccine to neoadjuvant chemotherapy increases the rate of complete pathologic response (CR). SECONDARY OBJECTIVES: I. Determine whether the addition of an IGFBP-2 vaccine to neoadjuvant chemotherapy increases progression free survival at 12 months. II. Determine whether the addition of an IGFBP-2 vaccine to neoadjuvant chemotherapy improves overall survival. III. To determine whether IGFBP-2 vaccination in combination with chemotherapy increases the level of tumor infiltrating lymphocytes (TIL) in the tumor. IV. To assess the level of IGFBP-2 type 1 helper cells (Th1) elicited with vaccination concurrent with chemotherapy. EXPLORATORY OBJECTIVES: I. To explore whether there is a predictive genomic signature for CR induction when IGFBP-2 vaccination is used in combination with chemotherapy. OUTLINE: Patients receive paclitaxel intravenously (IV) over 3 hours and carboplatin IV over 1 hour followed by IGFBP-2 vaccine intradermally (ID) 2 weeks later. Treatment repeats every 3 weeks for up to 3 cycles in the absence of disease progression or unacceptable toxicity. After completion of 3 cycles, patients then undergo cytoreductive surgery. After completion of study treatment, patients are followed up at 6 months and then once a year for 5 years.

Rate of Pathologic Complete Response (CR)At the time of cytoreductive surgery after receiving study treatment (vaccinations given intradermally approximately two weeks after each combination chemotherapy for 3 doses.)The tissue collected at time of cytoreductive surgery, post study treatment, was evaluated by the attending pathologist assigned to look at the tissue for viable tumor cells. The corresponding surgical pathology report was reviewed to evaluate individual pCR (absence of viable tumor cells).

Immunohistochemistry (IHC) Staining for CD3, CD4, CD8, and CD27At the time of cytoreductive surgeryWill be performed and quantitated using published methods and will be correlated with surgical CR by the Man-Whitney U or one-way analysis of variance test depending on the distribution of TIL outcomes.
Level of IGFBP-2 Th1 Cells Elicited With Vaccine Assessed by Enzyme-linked Immunosorbent Spot AssayUp to 6 months after last vaccineWill be correlated to tumor burden at definitive surgery.
Level of Tumor Infiltrating Lymphocytes (TIL) in TumorAt the time of cytoreductive surgery after receiving study treatment (vaccinations given intradermally approximately two weeks after each combination chemotherapy for 3 doses.)Will be assessed by immunohistochemistry (IHC) to determine whether IGFBP-2 vaccination in combination with chemotherapy increases the level of TIL in the tumor. This was done by assessing the level of IGFBP-2 Th1 elicited by study treatment (vaccination concurrent with chemotherapy). we are looking for an increase in TIL.
Progression Free Survival (PFS)Up to 12 monthsLarge differences in PFS if observed between the treatment groups will be noted and described. Will be plotted by Kaplan-Meier curve, and compared to the survival data reported by Vergote et al which reported median PFS of 12 months and median overall survival (OS) of 30 months for patients treated with neoadjuvant chemotherapy by a log-rank test.
