Phase Ib Trial of Two Folate Binding Protein Peptide Vaccines (E39 and J65) in Breast and Ovarian Cancer Patients

This is a single-center, randomized, single-blinded, three-arm phase Ib study of the folate binding protein vaccines E39 and J65. The study target population are patients with breast or ovarian cancer diagnosis who have been treated and are without evidence of disease. Disease-free subjects after standard of care multi-modality therapy will be screened and HLA typed. E39 and J65 are cytotoxic T-lymphocyte-eliciting peptide vaccines that are restricted to HLA-A2+ patients (approximately 50% of the U.S. population).
