Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The researchers are doing this study to find out whether the radiopharmaceutical therapy (RPT) 177Lu-PSMA-617 is a safe treatment for people with IDH wild type glioma.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

177Lu-PSMA-617

Patients will begin the first and second cycles of adjuvant Temozolomide (TMZ) the night before the first and second infusions of 177Lu-PSMA-617, respectively. Post-treatment, MRI of the brain will be obtained every 2 months, as per standard of care. A 68Ga-PSMA-PET scan will be performed with the MRI of the brain 1 month after the second cycle of 177Lu-PSMA-617 and again at evidence of disease progression.

Group Type EXPERIMENTAL

Temozolomide

Intervention Type DRUG

Patients will begin taking Temozolomide orally on the first 5 days of each 28-day cycle. The first dose will be given the evening before the first infusion of 177Lu-PSMA- 617.

177Lu-PSMA-617

Intervention Type DRUG

This agent will be given for 2-6 total doses, spaced 4 weeks (+/-1 week) apart. This will be administered on the 2nd day of the first two cycles of SOC adjuvant temozolomide.

68Ga-PSMA-PET scan/ MRI

Intervention Type DIAGNOSTIC_TEST

Approximately 4 weeks after cycle 2 of radiopharmaceutical therapy (RPT), patients will undergo post-treatment imaging with 68Ga- PSMA PET and MRI

Quality of Life Questionnaires

Intervention Type BEHAVIORAL

baseline assessments, QOL surveys will be conducted with XeQOL and FACT-Br at 6 months and 12 months post treatment
