Peptide-based Tumor Associated Antigen Vaccine for the Treatment of Patients with Malignant Gliomas, ETAPA I Trial

Trial Status: closed to accrual

This phase Ib trial tests the safety, side effects and best dose of P30-linked EphA2, cytomegalovirus (CMV) pp65, and survivin (P30-EPS) vaccine given with carboxymethlcellulose, polyinosinic-polycytidylic acid, and poly-L-lysine double stranded ribonucleic acid (RNA) (Hiltonol®) in treating patients with malignant gliomas. P30-EPS contains three different small proteins (peptides), pp65, EphA2 and survivin. The peptides in P30-EPS are designed to be tumor-specific antigens, which means the antigens are present only on tumor cells and not on other cells in the body. The immune system can recognize peptides on the surface of tumors as a signal to attack and fight the cancer. Hiltonol may further stimulate or enhance the activation of the immune system against the tumor. P30-EPS with Hiltonol may be a safe and effective treatment for patients with malignant gliomas.
