PET imaging with 68Ga-XT771 to detect CAIX/CAXII in glioblastoma and clear cell renal cell carcinoma

Clinical Evaluation of [68Ga]Ga-XT771 PET for Diagnosis in Patients With Glioblastoma and Clear Cell Renal Cell Carcinoma

Early Phase 1 Interventional Chinese PLA General Hospital · NCT07067905

This trial tests whether a PET probe called 68Ga-XT771 can help find CAIX/CAXII-expressing glioblastoma and clear cell renal cell carcinoma in adults.

What this trial studies

This is a prospective, open-label early phase 1 imaging study of 68Ga-XT771, a PET probe that targets the CAIX/CAXII proteins, in adults with glioblastoma or clear cell renal cell carcinoma. Participants will receive 68Ga-XT771 and undergo PET/CT imaging to characterize tracer uptake, biodistribution, safety, and tolerability. The study will collect imaging and safety data to determine how well the tracer detects CAIX/CAXII-expressing tumors and to describe its pharmacokinetics. Conducted at the Chinese PLA General Hospital, the trial is intended as an initial clinical evaluation to inform future larger studies.

Who should consider this trial

Good fit: Adults aged 18 or older with a diagnosis of glioblastoma or clear cell renal cell carcinoma who can give informed consent and attend the study visits are ideal candidates.

Not a fit: Pregnant or breastfeeding individuals, people with known allergies to the tracer components, or patients judged by investigators to have conditions unsuitable for the tracer are unlikely to benefit.

Why it matters

Potential benefit: If successful, 68Ga-XT771 PET could improve detection and localization of CAIX/CAXII-expressing tumors and help guide diagnosis or treatment planning.

How similar studies have performed: Other CAIX-targeted imaging approaches have shown promise in renal cell carcinoma, but 68Ga-XT771 is a novel probe and clinical data are limited, particularly for glioblastoma.
