Study of Metabolic, Transcriptomic and Proteomic Characteristics in Relapsed Glioblastoma

Study Purpose

Glioblastomas are the most frequent and aggressive malignant tumors of the CNS in adults, with almost systematic relapse despite treatment with surgery followed by radio-chemotherapy (STUPP protocol). The aim of this study is to better characterize transcriptomic, proteomic and metabolic changes in relapsed glioblastoma compared to the initial tumor, in order to identify new prognostic markers and potential new therapeutic targets.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- age > 18 years.

- surgery for both primary and recurrent glioblastoma between 2005 and 2023 at the CHU de Bordeaux.

Exclusion Criteria:

- systemic therapy received for non-glioblastoma tumor

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06430424
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Glioblastomas are the most frequent and aggressive malignant Central Nervous System (CNS) tumors in adults, with a median survival of only 14 months. Current treatment is based on surgery followed by radiochemotherapy (STUPP protocol), unchanged since 2005. Clinical trials evaluating immune checkpoint inhibitors and targeted therapies have largely failed to demonstrate efficacy in these tumors. In order to better understand the oncogenesis of glioblastoma and identify potential new therapeutic targets, the study of the characteristics of relapsed tumors compared with the initial tumor seems relevant. The aim of this retrospective study is to investigate the transcriptomic, proteomic and metabolic characteristics of relapsed glioblastomas reoperated at the University Hospital of Bordeaux, France, between 2005 and 2023, for which tumor material is available. These analyses will be correlated with relapse-free and overall survival of the patients.
