This phase II/III trial studies how well gallium Ga 68-labeled prostate specific membrane antigen (PSMA)-11 positron emission tomography/computed tomography (PET/CT) works in diagnosing patients with biochemical recurrent prostate cancer. Diagnostic procedures, such as gallium Ga 68-labeled PSMA-11 PET/CT, may help detect prostate cancer in patients with biochemical recurrent prostate cancer.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT03389451.
PRIMARY OBJECTIVES:
I. Determine sensitivity on a per-subject basis of gallium Ga 68-labeled PSMA-11 (68Ga PSMA-N,N'-bis [2-hydroxy-5-(carboxyethyl)benzyl] ethylenediamine-N,N'-diacetic acid [HBED-CC]) PET/CT for detecting tumor location, confirming with conventional imaging, clinical follow-up, and histopathology/biopsy where available.
SECONDARY OBJECTIVES:
I. Determine positive predictive value on a per-subject and per-region basis of 68Ga PSMA-HBED-CC PET/CT for detecting tumor location, confirming with histopathology and conventional imaging.
II. Continue to evaluate safety of 68Ga PSMA-HBED-CC injection as categorized by Common Terminology Criteria for Adverse Events (CTCAE) 4.03.
EXPLORATORY OBJECTIVES:
I. Determine the impact of 68Ga PSMA-HBED-CC PET/CT on clinical management in patients who have prostate cancer with biochemical recurrence.
II. Determine inter-reader reproducibility.
OUTLINE:
Participants receive gallium Ga 68-labeled PSMA-11 intravenously (IV) and undergo PET/CT over 25 to 40 minutes.
After completion of study treatment, participants are followed up at 1 days, then up to 12 months.
