Official title
Phase II/III Study for Evaluation of the Diagnostic Performance of [18F]CTT1057 PET Imaging for the Detection of PSMA Positive Tumors Using Histopathology as a Standard of Truth
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study was to evaluate the diagnostic performance of \[18F\]CTT1057 as a PET imaging agent for detection and localization of PSMA positive tumors using histopathology as Standard of Truth (SoT). Tissue specimens from both the primary tumor and pelvic lymph nodes dissected during surgery from patients with newly-diagnosed high-risk prostate cancer (PCa) were used for the histopathology assessments.
