Study Description

Brief Summary: Glioblastoma multiforme (GBM) are the most prevalent malignant tumor in central nervous system. At recurrence, no clear standard-of-care therapy is agreed for recurrent GBM (rGBM) and median overall survival is estimated to rarely exceed 6-9 months with effective therapies. Neoadjuvant therapy with anti-PD-1 monoclonal antibodies were confirmed to be helpful to extend survival in rGBM. Vaccine, dendritic cells (DCs) pulsed with glioblastoma stem-like cell (GSC) antigens (GSC-DCV), could extend survival for GBM patients in our previous clinical study (PMID: 30159779). The purpose of this study is to evaluate the safety and efficiency of using the neoadjuvant therapy with PD-1 antibody (Carilizumab) plus DC vaccine (GSC-DCV) in patients with recurrent glioblastoma.

Detailed Description: This is a phase II randomized controlled clinical study. The purpose of this research is to study the safety and efficacy of Camrelizumab alone or combined with GSC-DCV vaccines in treating patients with recurrent glioblastomas. The participants will be randomly assigned into two group. Patients in group A will receive neoadjuvant Camrelizumab (PD-1 antibody), followed by surgical resection, DC vaccines and further PD-1 inhibitor treatment until toxicity or progression. Patients in group B will receive neoadjuvant Camrelizumab (PD-1 antibody), followed by surgical resection, placebo and further PD-1 inhibitor treatment until toxicity or progression. Furthermore, to evaluate the associations between exploratory biomarkers, clinical outcomes, and adverse events based on the next generation sequencing.
