What is being measured
The primary outcome is the main question the study is designed to answer.
To assess the tolerability of the imaging agent subjects with metastatic clear cell RCC.
To assess the tolerability of RYZ512 by monitoring incidence and severity of AEs by NCI CTCAE v5, including SAEs, and other safety findings in subjects with metastatic clear cell RCC.
Measured: Study duration (6 months)
To evaluate the (long) biodistribution of RYZ512 in subjects with metastatic clear cell RCC.
To evaluate the (long) biodistribution of RYZ512 by using visual assessment of location, extent, and intensity of RYZ512 uptake in critical organs and tumors in subjects with metastatic clear cell RCC.
Measured: Study duration (6 months)
To evaluate the radiation absorbed doses of RYZ512 in critical organs and tumors as well as the effective dose in subjects with metastatic clear cell RCC.
To evaluate the radiation absorbed doses of RYZ512 using calculated mean TIAC (MBq·hr/MBq), radiation absorbed dose coefficients (mGy/MBq) and absorbed dose (Gy) to critical organs (e.g., stomach, liver, kidneys, bone marrow), calculated mean TIAC (MBq·hr/MBq) and radiation absorbed dose coefficients (mGy/MBq) and absorbed dose (Gy) to tumors, calculated whole-body effective dose (mSv/MBq) in critical organs and tumors as well as the effective dose in subjects with metastatic clear cell RCC.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing RYZ512 in people with Metastatic Clear Cell Renal Cell Carcinoma, run by RayzeBio, Inc. at 6 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Australia, South Africa, New Zealand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact RayzeBio Clinical Trials ((619) 657-0057, clinicaltrials@rayzebio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To assess the tolerability of the imaging agent subjects with metastatic clear cell RCC. (time frame: Study duration (6 months)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Oct 2026; AzTrials last refreshed its copy on 27 Oct 2026.
