Primary Outcome Measures :
  1. Specificity of 18F-DCFPyL PET/CT Imaging to Detect Metastatic Prostate Cancer Within the Pelvic Lymph Nodes Relative to Histopathology in High Risk Prostate Cancer Participants (Cohort A) [ Time Frame: Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]
    The primary analysis in Cohort A will test the co-primary endpoints of sensitivity and specificity of 18F-DCFPyL PET/CT imaging relative to histopathology for metastatic disease in pre-prostatectomy patients. For each co-primary endpoint there will be three independent imaging readers. At least two of the three readers must reject the null hypothesis for specificity to be deemed a success. If specificity is a success, then the same two readers need to reject the null hypothesis for sensitivity to reach overall success of the primary endpoint.

  2. Sensitivity of 18F-DCFPyL PET/CT Imaging to Detect Metastatic Prostate Cancer Within the Pelvic Lymph Nodes Relative to Histopathology in High Risk Prostate Cancer Participants (Cohort A) [ Time Frame: Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]
    The primary analysis in Cohort A will test the co-primary endpoints of sensitivity and specificity of 18F-DCFPyL PET/CT imaging relative to histopathology for metastatic disease in pre-prostatectomy patients. For each co-primary endpoint there will be three independent imaging readers. At least two of the three readers must reject the null hypothesis for specificity to be deemed a success. If specificity is a success, then the same two readers need to reject the null hypothesis for sensitivity to reach overall success of the primary endpoint.


Secondary Outcome Measures :
  1. Shift From Baseline in Selected Hematology Laboratory Values at Follow-up (Safety Outcome Measure) [ Time Frame: From time of screening (baseline) until pre-surgery/biopsy (within 28 days post-study drug dosing). ]
    Shifts from baseline to worst post-baseline visit for hematology laboratory values for all participants included in the Safety Set. The Safety Set includes all participants who received any amount of 18F-DCFPyL. Data are presented for participants in Cohort A and Cohort B.

  2. Shift From Baseline in Selected Clinical Chemistry Laboratory Values at Follow-up (Safety Outcome Measure) [ Time Frame: From time of screening (baseline) until pre-surgery/biopsy (within 28 days post-study drug dosing). ]
    Shifts from baseline to worst post-baseline visit for clinical chemistry laboratory values for all participants included in the Safety Set. The Safety Set includes all participants who received any amount of 18F-DCFPyL. Data are presented for participants in Cohort A and Cohort B.

  3. Changes From Baseline in Electrocardiogram (ECG) Parameters (Safety Outcome Measure) [ Time Frame: Changes in ECG pre-drug dosing and within 1-2 hours post-dosing ]
  4. Mean Changes From Baseline in Blood Pressure Post 18F-DCFPyL Dosing (Safety Outcome Measure) [ Time Frame: Measured at two intervals on the day of dosing, pre-dosing (baseline) and post-dosing/pre-imaging. ]
  5. Mean Change From Baseline in Heart Rate Post 18F-DCFPyL Dosing (Safety Outcome Measure) [ Time Frame: Measured at two intervals on the day of dosing, pre-dosing (baseline) and post-dosing/pre-imaging. ]
  6. Mean Change From Baseline in Respiration Rate Post 18F-DCFPyL Dosing (Safety Outcome Measure) [ Time Frame: Measured at two intervals on the day of dosing, pre-dosing (baseline) and post-dosing/pre-imaging. ]
  7. Mean Change From Baseline in Temperature Post 18F-DCFPyL Dosing (Safety Outcome Measure) [ Time Frame: Measured at two intervals on the day of dosing, pre-dosing (baseline) and post-dosing/pre-imaging. ]
  8. Sensitivity of 18F-DCFPyL PET/CT Imaging to Detect Prostate Cancer Within Sites of Metastasis or Local Recurrence Relative to Histopathology in Participants With Recurrent or Metastatic Prostate Cancer (Cohort B) [ Time Frame: Within 28 days of 18F-DCFPyL PET/CT imaging, conventional image-guided biopsy occurred. ]
    Sensitivity (True Positive rate) measures the proportion of positives that are correctly identified (i.e., the proportion of those who have some condition (affected) who are correctly identified as having the condition).

  9. Comparison of Detection Rates for Lesion Counts By Location and Overall Between 18F-DCFPyL PET/CT and Conventional Imaging [ Time Frame: Within 1-2 hours of 18F-DCFPyL dosing, a whole body PET/CT scan will be taken ]
    The number of lesions detected on imaging categorized as bone, visceral/soft tissue, lymph nodes, and the prostate gland will be determined by each of the central imaging core lab independent readers. The sum of lesions per participant per tissue type and overall will be computed for each participant based on each reader's lesion count. This will be calculated from the 18F-DCFPyL PET/CT scan results as well as the conventional imaging results.

  10. Positive Predictive Value (PPV) of 18F-DCFPyL PET/CT to Predict Prostate Cancer Within the Prostate Gland of High Risk Prostate Cancer Participants (Cohort A) [ Time Frame: Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]
    Positive Predictive Value (PPV) is based on a 18F-DCFPyL PET/CT image result and a histopathology result. The PPV is determined from the number of true positives (positive 18F-DCFPyL image and a positive histopathology result for prostate cancer) divided by the number of participants with a positive 18F-DCFPyL image.

  11. Negative Predictive Value (NPV) of 18F-DCFPyL PET/CT to Predict Prostate Cancer Within the Prostate Gland of High Risk Prostate Cancer Participants (Cohort A) [ Time Frame: Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]
    Negative Predictive Value (NPV) is based on a 18F-DCFPyL PET/CT image result and a histopathology result. The NPV is determined from the number of true negatives (negative 18F-DCFPyL image and a negative histopathology result for prostate cancer) divided by the number of participants with a negative 18F-DCFPyL image.

  12. Positive Predictive Value (PPV) of 18F-DCFPyL PET/CT to Predict Prostate Cancer Within the Lymph Nodes of High Risk Prostate Cancer Participants (Cohort A) [ Time Frame: Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]
    Positive Predictive Value (PPV) is based on a 18F-DCFPyL PET/CT image result and a histopathology result. The PPV is determined from the number of true positives (positive 18F-DCFPyL image and a positive histopathology result for prostate cancer) divided by the number of participants with a positive 18F-DCFPyL image.

  13. Negative Predictive Value (NPV) of 18F-DCFPyL PET/CT to Predict Prostate Cancer Within the Lymph Nodes of High Risk Prostate Cancer Participants (Cohort A) [ Time Frame: Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]
    Negative Predictive Value (NPV) is based on a 18F-DCFPyL PET/CT image result and a histopathology result. The NPV is determined from the number of true negatives (negative 18F-DCFPyL image and a negative histopathology result for prostate cancer) divided by the number of participants with a negative 18F-DCFPyL image.

  14. Positive Predictive Value (PPV) of 18F-DCFPyL PET/CT Imaging to Predict Prostate Cancer Within Sites of Local Recurrence and Other Metastatic Lesions in Participants With Recurrent or Metastatic Prostate Cancer (Cohort B) [ Time Frame: Within 28 days of 18F-DCFPyL PET/CT imaging, conventional image-guided biopsy will occur. ]
    Positive Predictive Value (PPV) is based on a 18F-DCFPyL PET/CT image result and a histopathology result. The PPV is determined from the number of true positives (positive 18F-DCFPyL image and a positive histopathology result for prostate cancer) divided by the number of participants with a positive 18F-DCFPyL PET/CT image.

  15. Peak Plasma Concentration (Cmax) of 18F-DCFPyL in a Subset of Participants [ Time Frame: Samples were collected at 0, 5, 15, 30, 60, 120, 240, 360, and 480 minutes after administration of 18F-DCFPyL. ]
  16. Area Under the Plasma Concentration Versus Time Curve (AUC) of 18F-DCFPyL in a Subset of Participants [ Time Frame: Samples were collected at 0, 5, 15, 30, 60, 120, 240, 360, and 480 minutes after administration of 18F-DCFPyL. ]
