Brief Summary
This early phase I trial studies how well an image-guided prostate biopsy using the imaging agent 68Ga-prostate-specific membrane antigen (PSMA)-11 with a positron emission tomography/computed tomography (PET/CT) scan works in diagnosing prostate cancer in men with a prior negative or inconclusive prostate biopsy. PSMA is a protein that is found on the surface of prostate cancer cells. 68Ga-PSMA-11 is made up of a substance that binds to PSMA on tumor cells, linked with a radioactive substance that can then be seen on imaging scans such as PET/CT. 68Ga-PSMA-11 PET/CT-guided biopsy may help improve the detection rate of prostate cancer. This may help reduce over-diagnosis and over-treatment in men with low-risk prostate cancer and under-treatment in men with high-risk prostate cancer.

Outcome Measures
Primary Outcomes (1)
Detection rate of clinically significant prostate cancer
Defined as the percentage of clinically significant prostate cancer (Gleason score 7 or more) in patients with focal 68Ga-PSMA-11 uptake within the prostate
Up to 3 years
Study Arms (1)
Diagnostic (68Ga-PSMA-11, image-guided prostate biopsy)
EXPERIMENTALSCREENING PROCEDURE: Patients receive 68Ga-PSMA-11 IV and 50-100 minutes later, undergo a PET/CT scan. Only patients with 68Ga-PSMA-11 uptake within the prostate proceed to image-guided biopsy. IMAGE-GUIDED BIOPSY: Patients undergo experimental image-guided prostate biopsy using PET/CT images obtained during screening procedure during a standard of care TRUS.
Interventions
Undergo image-guided prostate biopsy
Given IV
Undergo standard of care TRUS
Eligibility Criteria
You may qualify if:
- Men with suspicion of clinically significant prostate cancer with prior inconclusive, discordant or negative magnetic resonance imaging/ultrasound (MRI/US) fusion prostate biopsy
- Scheduled for a repeat transrectal ultrasound (TRUS) prostate biopsy by standard of care
- Focal 68Ga-PSMA-11 uptake within the prostate
You may not qualify if:
- Negative 68Ga-PSMA-11 uptake within the prostate (screening failure)
- Age \< 18 and \> 90 years
- Recurrent prostate cancer
- Inability to provide written informed consent
- Known inability to remain still and lie flat for the duration of the PET/CT (about 30 minutes)
