| Phase 3 |
Detailed Description
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.

Drug: Ga-PSMA-11
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.

Outcome Measures
Primary Outcome Measures
- Grade and record incidence of Adverse Events (AEs) to measure safety of Ga-PSMA-11 [4 years]
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. CTCAE version 5.0 will be used to grade AEs.
- Grade and record incidence of Adverse Events (AEs) to measure tolerability of Ga-PSMA-11 [4 years]
Adverse Events (AEs) will be collected and reviewed. Incidence and severity of AEs and adverse events will be estimated with 95% confidence intervals summarized with descriptive statistics. CTCAE version 5.0 will be used to grade AEs.
Secondary Outcome Measures
- Determine the frequency of positive PSMA PET scans in relation to the PSA value before the PSMA scans [4 years]
Results will be summarized descriptively with 95% confidence intervals. Determine rate of major and minor changes in management by comparing planned management strategy using conventional imaging and executed management strategy incorporating information from 68Ga-PSMA-11 PET/CT, regardless of treatment modality.
