Glioblastoma Evaluation for Heterogeneity In RadioseNsitivity

Study Purpose

This is an observational study on GBM surgical samples to investigate if increasing doses of radiation therapy could improve the radiation response; and in particular the investigators will assess if there is a correlation between the number of the phosphorylated H2AX nuclear foci and the different dose level of radiation therapy.

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.

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.

 NCT05556382
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

Standard of care for newly diagnosed glioblastoma (GBM) patients consists of surgical resection followed by radiotherapy with concurrent and adjuvant Temozolomide chemotherapy. Despite these treatments, the prognosis remains poor. Nevertheless, preliminary data on GBM patients show variable outcomes related to a different treatment response, that could be related to the GBM intrinsic heterogeneity, but also to a different patient sensitivity to radiation therapy. The assessment of this individual radio-sensitivity may provide valuable data to define more tailored treatment schedules, that could potentially be more effective. Published studies on small cohort of patients show that a possible system to investigate the tumor radiation sensitivity, is to monitor the cellular DNA damage after tissue irradiation, that correlates with the survival fraction of in vitro tumor cells; the DNA damage could be identified through the quantification of Phosphorylated histone H2AX nuclear foci that correlate with the unrepaired DNA double strand breaks (DSBs). Based on this background, The investigators designed an observational study on GBM surgical samples to investigate if increasing doses of radiation therapy could improve the radiation response; and in particular they will assess if there is a correlation between the number of the phosphorylated H2AX nuclear foci and the different dose level of radiation therapy.
