Now Enrolling: Solar Clinical Trials
Your patients undergoing staging for newly diagnosed prostate cancer or with suspected biochemical recurrent prostate cancer are invited to participate in Phase 3 clinical trials testing the diagnostic performance of copper Cu 64 PSMA I&T, a new agent for positron emission tomography (PET)/computed tomography (CT) imaging.
Copper Cu 64 PSMA I&T PET/CT imaging could be useful at different stages of a patient’s prostate cancer journey.
Please see each trial page for more information about eligibility.



About Copper Cu 64 PSMA I&T PET/CT
What Is Copper Cu 64 PSMA I&T PET/CT?
Copper Cu 64 PSMA I&T is a radioactive PET/CT imaging agent that specifically targets the prostate-specific membrane antigen (PSMA) protein, which is overexpressed in metastatic prostate cancers.
Copper Cu 64 has a longer half-life (12.7 hours) and shorter positron emission range than many other isotopes, which could enable high-quality image resolution.1,2
Clinical Development Overview
- Copper Cu 64 PSMA I&T PET/CT has been investigated in a Phase 1/2 study of 38 men with recurrent metastatic prostate cancer.
- It was determined in the Phase 2 trial that a single dose of 7-9 mCi copper Cu 64 PSMA I&T PET/CT enabled detection and localization of prostate lesions with sufficient image quality for diagnostic purposes.
- Copper Cu 64 PSMA I&T PET/CT was well tolerated in these studies, with no treatment-related adverse events and no changes in measured safety parameters.
The Phase 3 studies of copper Cu 64 PSMA I&T, a radiopharmaceutical, are being performed for research purposes only. Radiopharmaceuticals contribute to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Cu 64 PSMA I&T is not approved by the United States Food and Drug Administration. The safety and effectiveness of copper Cu 64 PSMA I&T have not been established. The medical benefits and risks of this agent are under investigation.
