Brief Summary:

This study evaluates the safety and diagnostic performance of 18F-DCFPyL Injection in patients with at least high risk prostate cancer who are planned for radical prostatectomy with lymphadenectomy (Cohort A) or in patients with locally recurrent or metastatic disease willing to undergo biopsy (Cohort B).

Cohort B is complete and no longer recruiting subjects.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Sensitivity and Specificity of 18F-DCFPyL PET/CT imaging to detect metastatic prostate cancer within the pelvic lymph nodes relative to histopathology in Cohort A [ Time Frame: Within 1-2 hours of dosing, whole body PET/CT scan will be taken. Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur. ]

Secondary Outcome Measures :
  1. Changes in clinical laboratory values [Safety and Tolerability] [ Time Frame: From time of screening until pre-surgery/biopsy (within 28 days post-study drug dosing) ]
  2. Changes in ECG related to 18F-DCFPyL administration [Safety and Tolerability] [ Time Frame: Changes in ECG pre-drug dosing and within 1-2 hours post-dosing ]
  3. Incidence of Treatment emergent adverse events [Safety and Tolerability] [ Time Frame: From study drug dosing until 10 days ]
  4. Sensitivity of 18F-DCFPyL PET/CT imaging to detect prostate cancer within sites of metastasis or local recurrence relative to histopathology in Cohort B [ Time Frame: Within 1-2 hours of dosing, whole body PET/CT scan will be taken. Within 28 days of imaging, biopsy will occur. ]
  5. Lesion count in different locations as detected by 18F-DCFPyL vs. conventional imaging [ Time Frame: Within 1-2 hours of dosing, whole body PET/CT scan will be taken ]
  6. Positive and negative predictive values (PPV and NPV) of 18F-DCFPyL PET/CT imaging to predict prostate cancer within the prostate gland and lymph nodes in Cohort A [ Time Frame: Within 1-2 hours of dosing, whole body PET/CT scan will be taken. Within 28 days of imaging, radical prostatecomy with pelvic lymph node dissection will occur. ]
  7. PPV of 18F-DCFPyL PET/CT imaging to predict prostate cancer within sites of local recurrence and other metastatic lesions in Cohort B [ Time Frame: Within 1-2 hours of dosing, whole body PET/CT scan will be taken. Within 28 days of imaging, biopsy will occur. ]
  8. Peak plasma concentration (Cmax) of 18F-DCFPyL in subset of patients [ Time Frame: At 0-8 hours post- dosing ]
    Summary statistics by timepoint

  9. Area under the plasma concentration vs time curve (AUC) of 18F-DCFPyL in subset of patients [ Time Frame: At 0-8 hours post- dosing ]
    Summary statistics by timepoint


Other Outcome Measures:
  1. Exploratory analysis of 18F-DCFPyL uptake in different lesion locations [ Time Frame: Within 1-2 hours of dosing, whole body PET/CT scan will be taken ]
  2. Pre-specified post hoc retrospective analysis of changes to clinical management plan based on central expert panel review of clinical and radiographic subject data before and after 18F-DCFPyL PET/CT scan results [ Time Frame: After enrollment is complete ]

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Histologically confirmed adenocarcinoma of the prostate.
  2. Subjects provide signed informed consent and confirm that they are able and willing to comply with all protocol requirements.

Cohort A Only:

  • At least high risk prostate cancer defined by NCCN Guidelines Version 3.2016 (clinical stage ≥T3a or PSA >20 ng/mL or Gleason score ≥8).
  • Scheduled or planned radical prostatectomy with PLND.

Cohort B Only: [Enrollment is complete; No longer recruiting subjects]

  • Radiologic evidence of local recurrence or new or progressive metastatic disease demonstrated on anatomical imaging (CT, MRI, or ultrasound), whole-body bone scan (99m-Tc-MDP or Na-18F) within 4 weeks of enrollment.
  • If prior treatment with radiation or ablative therapy, evidence of recurrence outside the confines of prior treated site(s) is needed.
  • Scheduled or planned percutaneous biopsy of at least one amenable lesion.

Exclusion Criteria:

  1. Subjects administered any high energy (>300 KeV) gamma-emitting radioisotope within five physical half-lives, or any IV iodinated contrast medium within 24 hours, or any high density oral contrast medium (oral water contrast is acceptable) within 5 days, prior to study drug injection.
  2. Subjects with any medical condition or other circumstance that, in the opinion of the investigator, compromise obtaining reliable data, achieving study objectives, or completion.

Cohort A Only:

  • Patients with prior androgen deprivation therapy or any investigational neoadjuvant agent or intervention

Cohort B Only: [Enrollment is Complete; No longer recruiting subjects]

  • Prior radiation or ablative therapy to intended site of biopsy, if within the prostate bed
  • Initiation of new therapy for recurrent and/or progressive metastatic disease since radiographic documentation of recurrence/progression.
