Personalized Cellular Vaccine for Glioblastoma (PERCELLVAC)
- Conditions
- Glioblastoma
- Interventions
- Biological: Personalized cellular vaccine
- Registration Number
- NCT02709616
- Lead Sponsor
- Guangdong 999 Brain Hospital
- Brief Summary
Dendritic cell-based cellular vaccine for tumor therapy has shown efficacy. This study is designed to perform a personalized clinical trial by first analyzing the expression of tumor associated antigens in patients with newly diagnosed glioblastoma and then immunizing the patients with personalized DC-based cellular vaccine. Immune responses to tumor antigens will be monitored. Safety and efficacy will be observed in the study.
- Detailed Description
This is an open label, single-arm, single-institution, Phase I study designed to investigate the safety and efficacy of personalized cellular tumor vaccine for patients with newly diagnosed glioblastoma (GBM). Newly diagnosed GBM patients will undergo tumor resection. The tumors will be analyzed for the expression of a panel of glioma-associated antigens and immune-related genes. Post surgical treatment will be 6 weeks standard chemotherapy with temozolomide and concurrent radiotherapy and continue cycles of temozolomide within a 28-day window. Patients will undergo leukapheresis either after surgery or after concurrent radio/chemotherapy. Based on individual tumor antigen expression, in vitro transcribed mRNA will be generated and used to pulse in vitro generated DCs. The patients will be immunized i.d. and i.v. biweekly with DC cellular vaccines. Safety and efficacy will be monitored. The primary objective is to assess the safety of the personalized cellular vaccines. The secondary objective is to assess the specific T cell response to immunized vaccines. In addition, the antitumor efficacy of the vaccines will be measured using iRANO criteria, progression-free survival and overall survival.
