Intervention

Drug:
• 212Pb-NG001
212Pb-NG001 is a targeted alpha-emitting radiopharmaceutical conjugated to a PSMA targeting peptide. Patients will receive an initial single 10 MBq dose IV to explore the imaging potential of 212Pb-NG001.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility of SPECT/CT gamma camera imaging for uptake of 212Pb-NG001	To qualitatively determine whether 212Pb-NG001 can be used to produce images of sufficient clarity and sensitivity by SPECT/CT to confirm 212Pb-NG001 uptake and biodistribution.	Up to 28 days
Secondary	Safety and tolerability	Number of participants with treatment-related adverse events as assessed by CTCAE v5.0	Up to 28 days
Secondary	Body clearance	To study body clearance of 212Pb-NG001 by gamma camera imaging and by sample and probe measurements.	Up to 2 days
Secondary	Therapeutic effect on prostate cancer as indicated by decreasing serum PSA and/or ALP	To explore any signals of therapeutic effects on the laboratory parameters: prostate specific antigen (PSA) and alkaline phosphatase (ALP)	Up to 28 days
