An Investigational Scan (68Ga-PSMA-11 PET) for the Imaging of Prostate Cancer

OUTLINE: Patients receive gallium Ga 68-labeled PSMA-11 intravenously (IV) over 60-75 minutes then undergo PET/CT or PET/magnetic resonance (MR) scan over 2-4 minutes per bed position at baseline. Patients receiving systemic therapy undergo an additional 68Ga-PSMA-11 PET/CT or PET/MR scan 12 weeks after initiating therapy. Patients may also undergo CT and bone scan during screening and on study. After the completion of study, patients are followed up at 60 days, 6 months, and annually up to 5 years or until time of first progression.
