Copper Cu 64 TP3805 PET in Detecting Prostate Cancer in Patients With Persistently Elevated PSA

April 22, 2025 updated by: Sidney Kimmel Cancer Center at Thomas Jefferson University

A Pilot Phase I Open Label Study of Cu-64-TP3805 PET Imaging for Detection of Prostate Cancer in Men With Persistently Elevated PSA

This pilot phase I trial studies how well copper Cu 64 TP3805 positron emission tomography (PET) works in detecting prostate cancer in patients with persistently elevated prostate specific antigen (PSA). The copper Cu 64 TP3805 PET scan uses copper Cu 64 TP3805, a compound made of a radioactive agent attached to a molecule that looks like a hormone that binds to cancer cells to detect prostate cancer during PET scans. Copper Cu 64 TP3805 PET may be able to see tumors at an earlier stage than the standard of care.
