Advanced Imaging-Guided Standard Versus Dose-Intensified Radiation Therapy for the Treatment of Newly Diagnosed Glioblastoma, SAGA 2.0 Trial

6 november 2026 bijgewerkt door: Mayo Clinic

Stereotactic Advanced-Imaging Guided Radiotherapy for Glioblastoma (SAGA 2.0)

This clinical trial studies how well advanced imaging-guided standard dose versus (vs.) dose-intensified radiation therapy (RT) and dose-intensified accelerated RT works in treating patients with newly diagnosed glioblastoma. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. During dose-intensified RT, a higher dose than normal of radiation therapy is delivered over 6 weeks. During dose-intensified accelerated RT, the higher dose of radiation therapy is delivered over a shorter amount of time (2 weeks) than normal (6 weeks). Patients also undergo an advanced brain imaging positron emission tomography (PET)/computed tomography (CT) scan (using a radioactive drug called either FET or FDOPA) prior to RT to that may help doctors better plan the treatment. Dose-intensified and dose-intensified accelerated radiation therapy may be effective in treating patients with newly diagnosed glioblastoma. Giving dose-intensified RT or dose-intensified accelerated RT guided by advanced imaging may work better than standard dose RT in treating patients with newly diagnosed glioblastoma.

Maatregel Beschrijving
Tijdsspanne
Overall survival (Cohort 1)
Tijdsspanne: Up to 18 months

Overall survival (OS) is defined as the time from registration until death due to any cause. Will be summarized by treatment arm using the difference in proportions test.

Up to 18 months
Overall survival (Cohort 2)
Tijdsspanne: Up to 12 months

Overall survival (OS) is defined as the time from registration until death due to any cause. A Bayesian pick-the-winner design will be used to identify the more promising treatment arm based on 12-month overall survival.

Maatregel Beschrijving
Tijdsspanne
Incidence of grade 3+ central nervous system (CNS) toxicity, regardless of attribution (Overall CNS toxicity)
Tijdsspanne: Up to 36 months post-radiation therapy (RT)

CNS toxicities will be graded according to Common Terminology Criteria for Adverse Events (CTCAE) 5.0. For each treatment arm, CNS toxicity will be summarized as: the number and proportion of patients experiencing at least one qualifying grade ≥ 3 CNS toxicity event. Between-arm comparisons will be performed descriptively.

Up to 36 months post-radiation therapy (RT)
Incidence of grade 3+ higher CNS toxicity at least possibly attributable to radiation therapy (Treatment-related CNS toxicity)
Tijdsspanne: Up to 36 months post-RT

As assessed by the treating investigator. CNS toxicities will be graded according to CTCAE 5.0. Events classified as possibly, probably, or definitely related to radiation therapy will be included. For each treatment arm, CNS toxicity will be summarized as: the number and proportion of patients experiencing at least one qualifying grade ≥ 3 CNS toxicity event.

Up to 36 months post-RT
Quality of life (Cohort 1) - EORTC QLQ-C30
Tijdsspanne: Up to 6 months post-RT

Tijdsspanne: Up to 1 month post-RT

As measured by Mayo Test Drive (MTD), a web-based platform for remote self-administered cognitive assessment. The primary comparison will be the between-arm difference in mean change over time (arm-by-time interaction). Higher or average composite scores indicate functioning consistent with healthy cognitive peers for participant's age, sex, and education. Significantly negative scores suggest performance drops in memory and processing. An MTD score is a screening and monitoring tool, not a medical diagnosis. Lower scores do not automatically indicate Alzheimer's or dementia; they can be influenced by other factors such as fatigue, high stress, medications, technical issues during the test, or mild age-related changes.
