Spots Global Cancer Trial Database for Gallium Ga 68-labeled PSMA-11 PET/CT in Detecting Recurrent Prostate Cancer in Patients After Initial Therapy

Study Description

Brief Summary: This clinical trial studies how well gallium Ga 68-labeled prostate-specific membrane antigen (PSMA)-11 positron emission tomography (PET)/computed tomography (CT) works in detecting prostate cancer that has come back (recurrent) in patients after initial therapy. Diagnostic procedures, such as gallium Ga 68-labeled PSMA-11 PET/CT, may help doctors detect tumors that have come back after initial therapy.

Detailed Description: PRIMARY OBJECTIVE: I. To assess the sensitivity on a per-patient and per-region-basis of Gallium Ga 68 Gozetotide (68Ga-PSMA-11) PET for detection of tumor location confirmed by histopathology/biopsy, clinical and conventional imaging follow-up. SECONDARY OBJECTIVES: I. To assess the positive predictive value (PPV) on a per-patient and per-region-basis of 68Ga-PSMA-11 PET for detection of tumor location confirmed by histopathology/biopsy, clinical and conventional imaging follow-up (composite reference standard). II. To assess the sensitivity and positive predictive value (PPV) on a per-patient and per-region-basis of 68Ga-PSMA-11 PET for detection of tumor location confirmed by histopathology/biopsy only. III. To assess the detection rates on a per-patient basis of 68Ga-PSMA-11 PET stratified by prostate specific antigen (PSA) value (0.2 - \< 0.5, 0.5 - \< 1.0, 1.0 - \< 2.0, 2.0 - \< 5.0, \>= 5.0). IV. To assess the impact of 68Ga-PSMA-11 PET on clinical management in biochemical recurrence (BCR) patients. V. To assess the inter-reader reproducibility. VI. To assess the safety of 68Ga-PSMA-11 PET. VII. To assess the detection rates on a per-patient basis of 68Ga-PSMA-11 PET stratified by PSA velocity and PSA doubling-time. OUTLINE: Patients receive gallium Ga 68-labeled PSMA-11 intravenously (IV). Beginning 50-100 minutes after receiving gallium Ga 68-labeled PSMA-11, patients undergo PET imaging. After completion of study, patients are followed up for 3-12 months.
