Vaccination-Dendritic Cells With Peptides for Recurrent Malignant Gliomas

Summary

This is a single-institution Phase I/II study designed to evaluate the safety and induction of an immune response, and preliminary clinical response of vaccinations with Type-1 alpha-DCs (alpha-DC1) loaded with glioma-associated antigen (GAA) epitopes and administration of poly-ICLC in patients with recurrent malignant gliomas. Approximately 30 subjects will be enrolled in this study at UPMC/UPCI Hillman Cancer Center. The study participants in this trial will be HLA-A2 positive male or female adults over 18 years of age. The primary objective is to establish the safety of this approach. The endpoints will be to determine the maximum tolerated dose (MTD) of alpha-DC1 vaccines in combination with a fixed dose of poly-ICLC, using standard criteria and close clinical followups. The secondary objectives are 1) to assess the immunological response against GAAs in patients with recurrent malignant gliomas immunized with DCs loaded with GAA-derived peptides using enzyme-linked immuno-spot (ELISPOT), delayed-type hypersensitivity (DTH) and tetramer assays; and 2) to assess the preliminary anti-tumor clinical activity of the vaccines as measured by radiological response (MRI), overall survival, and 4- and 6-month progression-free survival (PFS).
