Study of Neoantigen-specific Adoptive T Cell Therapy for Newly Diagnosed MGMT Negative Glioblastoma Multiforme (GBM)

Summary

This randomized study is designed to compare the combination of TVI-Brain-1 immunotherapy and standard therapy compared to standard therapy alone as a treatment for newly diagnosed MGMT unmethylated glioblastoma patients. The patients' own cancer cells collected after surgery are combined into a vaccine to produce an immune response that significantly increases the number of cancer neoantigen-specific effector T cell precursors in the patient's body. These cancer neoantigen-specific T cells are harvested from the blood, subsequently stimulated and expanded, and infused back into the patient.
