  Purpose
Folate binding protein (FBP) is highly over-expressed in breast, ovarian and endometrial cancers and is the source of immunogenic peptides (E39) that can stimulate cytotoxic T lymphocytes (CTL) to recognize and destroy FBP-expressing cancer cells in the laboratory. The purpose of this study is to test whether a peptide-based vaccine consisting of the E39 peptide mixed with the FDA-approved immunoadjuvant granulocyte macrophage colony-stimulating factor (GM-CSF) is safe and effective at inducing an in vivo peptide-specific immune response. Furthermore, the investigators intend to determine the best dose of the vaccine to utilize to produce this immunity most efficiently. The investigators will determine whether immunity to FBP will prevent clinical recurrence. Additionally, the investigators will compare these results with results from a trial utilizing the E75 peptide (from the HER2/neu protein) in ovarian and endometrial cancer patients in preparation for studying a combination vaccine.

Primary Outcome Measures:
  • Safety and Local/Systemic Toxicity [ Time Frame: Duration of the vaccine series ]
    Standard local and systemic toxicities will be collected and graded per the National Cancer Institute Common Terminology Criteria for Adverse Events, v4.03 toxicity scale. For the vaccine series (one vaccine/month for six months), patients will be monitored closely for one hour after vaccine inoculation with questioning, serial exams and vital signs every 15 minutes to observe for a hypersensitivity reaction. Patients will also return to the clinic 48-72 hours after each inoculation for questioning regarding systemic toxicity and to examine and measure inoculation site local reactions.


Secondary Outcome Measures:
  • Disease-free survival [ Time Frame: Disease-free survival up to 36 months ]
    Disease-free survival (DFS) for all patients regardless of randomization will be determined by the patients' own physicians at the individual study sites during routine follow-up screening. This will occur every three months for the first 24 months after diagnosis and then every six months for an additional 36 months.


Estimated Enrollment: 60
Study Start Date: April 2012
Estimated Study Completion Date: April 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Non-vaccine clinically matched control group
Patients who meet all inclusion criteria and none of the exclusion criteria will be HLA typed. HLA-A2+ patients will be offered the vaccine. HLA-A2-negative patients and HLA-A2+ patients who decline the vaccine will be followed clinically as matched controls for disease recurrence/progression.
Other: Clinical tracking for disease progression/recurrence
HLA-A2-negative patients or HLA-A2-positive patients who decline the vaccine will be followed clinically as matched controls for disease recurrence/progression. No experimental treatment will be administered to this group.
Experimental: E39 peptide/GM-CSF vaccine
HLA-A2+ patients receive E39 peptide/GM-CSF vaccine intradermally every 3-4 weeks for a total of up to six inoculations.
Biological: E39 peptide vaccine
100mcg, 500mcg and 1,000mcg of lyophilized E39 peptide is suspended in bacteriostatic water for injection in individual cryovials and frozen. At the time of vaccine administration, the suspended peptide is thawed and mixed thoroughly with 250mcg GM-CSF in the syringe. This constitutes the E39 vaccine.
Other Names:
  • E39 peptide (FBP, 191-199, EIWTHSTKV)
  • GM-CSF (sargramostim)
