This is a multi-center, single-arm, open-label prospective study to evaluate the diagnostic performance of [18F]CTT1057 as a PET imaging agent for detection and localization of PSMA positive tumors, using histopathology as SoT. Tissue specimens from both the primary tumor and pelvic lymph nodes dissected during surgery from patients with newly-diagnosed high-risk PCa will be used for the histopathology assessments. All participants will receive [18F]CTT1057 for PET/CT scan imaging, and surgery (radical prostatectomy and extended pelvis lymph node dissection) will be performed up to 6 weeks after [18F]CTT1057 PET for pathology assessment of the tissue specimens. The co-primary endpoints of patient-level sensitivity and region-level specificity will be assessed by comparing the central reading results of the [18F]CTT1057 PET scan to the histopathology results in the dissected tissue specimens, i.e. both the primary tumor and the dissected Pelvic Lymph Node (PLN)). Pathology will be assessed by the local pathologists as per Standard of Care (SoC), who will be blinded to the PET data.
