Is this trial a fit for you?

Likely a good fit

Adults (18+) with biopsy-proven metastatic clear cell RCC.

Probably not a fit

Patients who cannot stop certain medications or who are pregnant or breastfeeding may not receive imaging benefits.

What this trial studies

This early phase1 imaging study will evaluate the feasibility, biodistribution, and dosimetry of the imaging agent RYZ512 in adults with metastatic clear cell RCC. Participants will receive the imaging agent and undergo imaging procedures to characterize how it distributes in the body and the radiation dose delivered. The study seeks to determine whether the agent can be safely used for imaging in this cancer type and to inform future dosing and timing. No efficacy outcomes are the primary focus; safety, distribution patterns, and dosimetry are the key endpoints.

Why it matters

Potential benefit: If successful, patients could benefit from more precise imaging to guide treatment decisions.

How similar studies have gone: Previous imaging agents in RCC have shown informative biodistribution patterns, but this specific agent’s imaging performance is being evaluated.
