Summary

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.

Conditions

Interventions

OTHER

Blood and urine sampling

Staff will perform the IV blood draws and collect urine samples

PROCEDURE

laparoscopic radical prostatectomy and bilateral pelvic LN dissection or a salvage lymph node dissection

Surgery will be performed within 24 h of the third PET/MRI scan.

DRUG

89Zr-DFO-PSMAi-PEG-Cy5.5-C' dots

Patients (up to 6) will receive an intravenous (IV) injection of approximately 5-7 mCi (+/- 10%) of PSMA-targeting C' dot tracer within 24-48 h before surgery. Patients will then undergo one preoperative PET/MR imaging

DIAGNOSTIC_TEST

PET/MRI/fluorescence imaging

Imaging will be performed using the GE Signa PET/MRI.

DRUG

(64Cu)-NOTA-PSMAi-PEG-Cy5.5-C' dot tracer

Patients will be injected with approximately 6-7 mCi (+/- 10%) of 64Cu-NOTA-PSMAi-PEG-Cy5.5-C' dots
