Patients will receive a single dose of 68Ga-PSMA-11 and undergo a PET/CT or PET/MRI imaging study.
This is a prospective, Phase III, single-center, open-label to provide extended access in patients with biochemically recurrent prostate cancer. Approximately 100 patients are planned for enrollment in this study. Patients will receive a single dose of 68Ga-PSMA-11 and undergo a PET/CT or PET/MRI imaging study.
The intervention is a PET scan with the radiolabelled Prostate-specific membrane antifen (PSMA) ligand, 68Ga-PSMA-11. The PET may be combined with a CT scan as a PET/CT or an MRI scan as PET/MRI. 68Ga-PSMA-11 PET/CT will be acquired using a modern digital GE PET/CT scanner or a modern digital PET / MRI scanner.
AEs will be collected during injection and uptake phase (45-120 min posts infusion) of Ga-68 PSMA-11 PET/CT scan. All safety events will be recorded up to 120 min post injection.
Men with pathologically proven prostate adenocarcinoma, high risk cancer at diagnosis, evidence of biochemical recurrence, or known metastatic disease planned to start and change systemic therapy regimen.
One intravenous catheter will be placed for radiopharmaceutical administration. Patients will be injected with 100 MBq (3mCi)-300 MBq( 7mCi) of 68Ga-PSMA-11 via this catheter.

| Ga-PSMA-11 | Drug | The PSMA Sterile Cold Kit, is a kit comprising all needed materials (lyophilized PSMA for PSMA reconstitution, elution vial for Ga and ancillary materials for transfer between vials) to perform a room-temperature radiolabelling of PSMA-11 with Ga. Ga is not part of the kit and should be provided in the form gallium chloride solution following the requirements of the relevant local regulations. PSMA-11 radiolabelled with Ga is administered in patients with prostate cancer recurrence after radical treatment. |

| Number of Participants With Adverse Events | Adverse Events (AEs) will be collected and reviewed to monitor for safety. Incidence and severity of AEs and adverse events will be estimated with 95% confidence intervals summarized with descriptive statistics.

| Measure | Description | Time Frame |
|---|---|---|
| Compare the Diagnostic Impact of 68Ga-PSMA-11 PET/CT Imaging Over Current Standard of Care Imaging Modalities. | Determine the frequency of positive PSMA PET scans in relation to the PSA value before the PSMA scans and compared to conventional imaging. Results will be summarized descriptively with 95% confidence intervals. Determine rate of overall changes in management by comparing planned management strategy using conventional imaging with executed management strategy incorporating information from 68Ga-PSMA-11 PET/CT, regardless of treatment modality. Analysis: The rate of change in management based on the incorporation of68Ga-PSMA-11 PET/CT results will be expressed as the percentage of total patients imaged in which change in management occurred, regardless of treatment modality. The rate of change in management will also be estimated within each group (initial staging, biochemical recurrence, and pre/post treatment). 95% confidence intervals (CIs) will be used to express precision of the estimates. |
