Is this trial a fit for you?

Likely a good fit

Adults with suspected or confirmed kidney cancer, measurable lesions, and adequate organ function who can comply with follow-up and contraception requirements.

Probably not a fit

Patients without CAIX expression in their tumors or with contraindications to PET imaging may not see diagnostic benefit.

What this trial studies

This early Phase 1 trial investigates whether 68Ga/18F-CAIX-LT-BCH PET/CT can safely image CAIX-expressing kidney tumors. Eligible participants have confirmed kidney cancer with at least one measurable lesion and adequate organ function. Participants will receive a single PET/CT scan after administration of the tracer to assess imaging quality, safety, and preliminary tumor targeting. The study emphasizes non-invasive, real-time visualization of tumors to support diagnosis and treatment planning. Overall, results will inform feasibility and potential utility of CAIX-directed molecular imaging in ccRCC.

Why it matters

Potential benefit: If successful, patients may benefit from improved non-invasive detection and localization of CAIX-expressing tumors to guide management.

How similar studies have gone: Previous work supports CAIX as a target in ccRCC imaging, but this exact tracer approach is still exploratory in humans.
