简要总结
This phase II trial studies the side effects of autologous dendritic cells pulsed with tumor lysate antigen vaccine and nivolumab and to see how well they work in treating patients with glioblastoma that has come back. Vaccines made from a person's tumor cells may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread. Giving dendritic cell-autologous lung tumor vaccine and nivolumab may work better in treating patients with glioblastoma.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the safety and tolerability of the combination treatment of autologous dendritic cells pulsed with tumor lysate antigen vaccine (DCVax-L) and nivolumab.
II. To compare overall survival (OS) from the date of surgery in a pooled evaluation of group 1 subjects receiving DCVax-L and group 2 subjects receiving DCVax-L and nivolumab to recent historical standards.
III. To compare OS between the two groups.
