PRIMARY OBJECTIVE:

• I. To verify the specificity of Zr-89 crefmirlimab berdoxam CD8+ minibody immunoPET in identifying regions of immune cell activity in human glioma patients using stereotactic image-guided biopsies and multiplexed immunohistochemistry (IHC).

EXPLORATORY OBJECTIVE:

• I. To evaluate the associations between exploratory biomarkers, clinical outcomes, and adverse events which include: Ia.

Exploring whether changes in specific magnetic resonance imaging (MRI) parameters correlate with tumor and peripheral blood immune responses; Ib. Assessing the potential change in Zr-89 crefmirlimab berdoxam uptake in tumor tissue and correlation with CD8 infiltrate in tumor tissue; Ic. Explore the correlation of visual and semi-quantitative Zr-89 crefmirlimab berdoxam PET measurements with clinical outcome. OUTLINE: Patients receive Zr-89 crefmirlimab berdoxam intravenously (IV) over 5-10 minutes 3 days prior to scheduled surgical resection. Approximately 24 hours after receiving Zr-89 crefmirlimab berdoxam, patients undergo immuno-PET scans. Patients then undergo scheduled standard of care surgical resection of the brain tumor and brain biopsy. Additionally, patients undergo advanced physiologic and metabolic magnetic resonance imaging (MRI) and MRI prior to surgery on study. After completion of study treatment, patients are followed up until death.

Experimental: Treatment (Zr-89 crefmirlimab berdoxam + ImmunoPET)

Patients receive Zr-89 crefmirlimab berdoxam IV over 5-10 minutes 3 days prior to scheduled surgical resection. Approximately 24 hours after receiving Zr-89 crefmirlimab berdoxam, patients undergo immuno-PET scans. Patients then undergo scheduled standard of care surgical resection of the brain tumor and brain biopsy. Additionally, patients undergo advanced physiologic and metabolic MRI and MRI prior to surgery.
