A Prospective Study to Better Understand the Molecular, Immune and Metabolic Mechanisms Involved in Glioblastoma Recurrence and Progression, in the Aim to Identify New Therapeutic Targets and to Improve Current Therapies
BORDEAUX-GLIO is a prospective, monocentric study which will describe the molecular, immune and metabolic pathways involved in the progression and relapse of glioblastoma, using blood and tumor samples from patients who have undergone surgery for newly diagnosed or recurrent glioblastoma in the center.
Glioblastoma is the most common and aggressive primary brain tumor in adults, whose relapse is almost systematic despite surgery, radiation therapy and temozolomide (STUPP protocol). Several clinical trials evaluating targeted therapy and immune checkpoint inhibitors have led to disappointed results. There is an unmet need to better understand the molecular and immune mechanisms underlying the invasion and progression of these tumors, in order to identify new therapeutic targets. The Bordeaux University Hospital is a leading French treatment center for glioblastoma, providing a large number of biological samples that can be analyzed at the molecular, immune and metabolic levels by specialized local teams.
Tumor tissue will be collected during patient surgery from primitive or recurrent glioblastoma, as well as blood samples, to perform transcriptomic and metabolomic analysis, including spatial transcriptomic and metabolomic, ex vivo generation of γδT lymphocytes and patient-derived xenografts.
A secondary objective is to develop, in preclinical models, innovative drugs with radiosensitizing effect and a γδT cell immunotherapy active against glioblastoma.
