68Ga-PSMA PET/CT or PET/MRI in Evaluating Patients With Recurrent Prostate Cancer

Not Recruiting

Trial ID: NCT02488070


This clinical trial studies gallium-68 (68Ga)-prostate specific membrane antigen (PSMA) (gallium Ga 68-labeled PSMA ligand Glu-urea-Lys[Ahx]) positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) in identifying prostate cancer that may have returned after a period of improvement (biochemical recurrence). 68Ga-PSMA is a radiopharmaceutical that localizes to a specific prostate cancer receptor, which can then be imaged by the PET/CT or PET/MRI scanner.

Inclusion Criteria:

   - Provides written informed consent

   - Known diagnosis of prostate cancer

   - Patient has suspected recurrence based on biochemical data (prostate specific antigen
   [PSA] > 2 ng/mL)

   - Able to remain still for duration of each imaging procedure (about one hour)

Exclusion Criteria:

   - Unable to provide informed consent

   - Inability to lie still for the entire imaging time

   - Inability to complete the needed investigational and standard-of-care imaging
   examinations due to other reasons (severe claustrophobia, radiation phobia, etc.)

   - Any additional medical condition, serious intercurrent illness, or other extenuating
   circumstance that, in the opinion of the Investigator, may significantly interfere
   with study compliance
