PyL in Patients With High Risk and Biochemically Recurrent Prostate Cancer

2-(3-{1-carboxy-5-[(6-18F-fluoro-pyridine-3-carbonyl)-Amino]-Pentyl}-Ureido)-Pentanedioic Acid (PyL) in Patients With High Risk and Biochemically Recurrent Prostate Cancer

Who can join

Ages 18 and older · Men

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

About the study

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.
