Zr-89 Crefmirlimab Berdoxam and Immuno-Positron Emission Tomography for the Imaging of Patients With Resectable Brain Tumors

Study Purpose

This phase I trial studies how well zirconium (Zr)-89 crefmirlimab berdoxam and immuno-positron emission tomography (PET) identifies areas of immune cell activity in patients with brain tumors that can be removed by surgery (resectable). One important predictor of the immune response is the presence and change in CD8 positive (+) tumor infiltrating lymphocytes (TIL) cells. Identifying the presence and changes in CD8+ cells can be challenging, particularly for participants with central nervous system (CNS) tumors, and usually requires invasive procedures such as repeat tissue biopsies, which may not accurately represent the immune status of the entire tumor. Zr-89 crefmirlimab berdoxam is known as a radioimmunoconjugate which consists of a radiolabeled anti-CD8+ minibody whose uptake can be imaged with PET. Upon administration, Zr 89 crefmirlimab berdoxam specifically targets and binds to the CD8+ cells. This enables PET imaging and may detect CD8+ T-cell distribution and activity and may help determine the patient's response to cancer immunotherapeutic agents more accurately. Giving Zr-89 crefmirlimab berdoxam along with undergoing immuno-PET imaging may work better at identifying immune cell activity in patients with resectable brain tumors.

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.	Interventional
Eligible Ages	18 Years and Over

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.	NCT06650163
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.	Phase 1

Additional Details

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.
