Phase III Study for Evaluation of the Diagnostic Performance of [18F]CTT1057 PET Imaging in Patients With Prostate Cancer With Rising PSA Levels [Biochemical Recurrence (BCR)]

Novartis Pharmaceuticals·interventional·Posted Apr 9, 2021·Updated Oct 20, 2025

In Brief

A Phase 3 clinical trial evaluating [18F]CTT1057 and [68Ga]Ga-PSMA-11 for Prostatic Neoplasms and 2 related conditions. Completed, enrolled 190 participants across 13 sites in 4 countries.

Detailed Summary

The current study aimed at evaluating the diagnostic performance of \[18F\]CTT1057 as a PET imaging agent for detection and localization of Prostate specific membrane antigen (PSMA) positivity in patients diagnosed of biochemical recurrence of prostate cancer (PCa), using a composite truth standard. Approximately 190 participants were to be enrolled to ensure at least 152 participants were evaluable (i.e. have both an evaluable \[18F\]CTT1057 Positron emission tomography/Computed Tomography (PET/CT) scan imaging and at least one evaluable Composite Truth Standard (CTS) assessment and had not received any prohibited systemic antineoplastic therapy before the completion of PET/CTs and CTS procedures, which were required for the calculation of the co-primary endpoints.
