What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Procedures mentioned: MRI scans, Injections

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "The researchers want to determine whether pre-operative PET/MRI scans and intra-operative optical imaging performed in prostate cancer patients after the injection of one of these investigational tracers more accurately localizes cancerous deposits within the surgical bed as compared with conventional imaging scans alone."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

The purpose of this study is to see whether using the copper-64 (64Cu) or zirconium-89 (89Zr) radiolabeled PSMA-targeting C' dot tracer, termed 64Cu-NOTA-PSMAi-PEG-Cy5.5-C' dots or 89Zr-DFO-PSMAi-PEG-Cy5.5-C' dots, is a safe way to identify tumor cells before and during surgery for prostate cancer. The researchers want to determine whether pre-operative PET/MRI scans and intra-operative optical imaging performed in prostate cancer patients after the injection of one of these investigational tracers more accurately localizes cancerous deposits within the surgical bed as compared with conventional imaging scans alone. The researchers will study how the tracer travels through your body and where it is distributed. This study is the first time that the tracer will be used in patients undergoing surgery for prostate cancer.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
