Brief Summary

The standard of care imaging of prostate cancer metastases recommended by the National Comprehensive Cancer Network (NCCN), CT of the chest/abdomen/pelvis and bone scan, may be suboptimal. PyL is a novel PET tracer designed to detect prostate specific membrane antigen (PSMA) expressed on prostate cancer cells. PyL PET/CT may provide improved evaluation of clinically significant metastases in patients with prostate cancer.

Eligibility Criteria

Inclusion Criteria: 1. Male ≥ 18 years of age. 2. Histologically confirmed adenocarcinoma of the prostate 3. Patients meet one of the follow criteria: Cohort 1: High risk prostate cancer (PSA \>10, Gleason 8-10, or clinical stage \>T2c) and planned prostatectomy or radiation therapy or Cohort 2: Biochemical prostate cancer relapse (Prostate Specific Antigen (PSA) \> 0.2 ng/ml in patients following prostatectomy or ≥ 2 ng/ml more than the PSA nadir in patient following radiotherapy, as defined by the ASTRO-Phoenix criteria \[18\] and no evidence of malignancy on standard of care imaging for metastases (CT of the chest/abdomen/pelvis and bone scan) within 3 months. Exclusion Criteria: 1. Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data. 2. Patients who cannot undergo PET/CT scanning because of weight limits. PET/CT scanners may not be able to function with patients over 450 pounds. 3. Change in therapy since standard of care imaging
