    Overall Study
pre Assignment Details
Baseline safety evaluations performed at screening (Visit 1) comprised vital signs and recording of any adverse events (AEs) from the time of informed consent. Conventional images collected within 90 days of rhPSMA7.3 (18F) PET, followed by biopsy within 60 days post-PET scan or confirmatory imaging within 90 days post-PET scan
recruitment Details
This study was conducted from 04 May 20 (first patient, screening visit) and 12 Oct 21 (database lock), with last patient, last visit on 28 Apr 21. It was conducted at 28 activated study sites (27 recruited) in 3 countries. Of the 420 patients screened, 391 patients met all the study eligibility criteria
