Is this trial a fit for you?

Likely a 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.

Probably 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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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 gone: 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.
