This is a multi-centre, blinded review, dose ranging, non-randomized study of 64Cu-SAR-bisPSMA administered to participants with confirmed Prostate Cancer. 30 eligible participants will be allocated (1:1:3) to 1 of 3 dosing cohorts to be administered with 64Cu-SAR-bisPSMA 100 MBq, 150 MBq or 200 MBq. PET/CT scan images will be sent to blinded central readers to assess the capacity of 64Cu-SAR-bisPSMA to detect primary Prostate Cancer, to assess image quality of the various dose cohorts, and to assess the PET/CT scan features of 64Cu-SAR-bisPSMA in comparison standard of care.
