Zr-89 Crefmirlimab Berdoxam and Immuno-Positron Emission Tomography for the Imaging of Patients With Resectable Brain Tumors (NCT06650163)

Biologic Validation of Zr-89 Crefmirlimab Berdoxam CD8+ Minibody ImmunoPET in Human Brain Tumors

๐ŸŸข Recruiting Phase1 ๐Ÿฉบ Clinical Procedure Protocol Sponsor: Jonsson Comprehensive Cancer Center

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
