Outcome Measures
Primary Outcomes (3)
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.
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.
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.
