Purpose

The purpose of this study is to learn whether PYLARIFY PET imaging (study scan) can safely and accurately detect the presence or absence of prostate cancer growing beyond the prostate gland in men with favorable intermediate risk prostate cancer. Participants will receive a single dose of PYLARIFY injection followed by a single whole-body PET/CT or PET/MRI scan acquired at 1 to 2 hours after PYLARIFY injection. Participants with positive study scan results that are suspicious for prostate cancer outside of the prostate gland may be asked to undergo additional diagnostic test(s) and/or recommend certain treatment(s) for prostate cancer within 2 to 90 days after the study scan. Participants will be monitored for up to 12 months to collecting information about treatment they receive for prostate cancer and results of regular PSA blood draws if ordered by doctors for up to 12 months after the study scan.

Exclusion Criteria

  1. Patients administered any high energy (>300 KeV) gamma-emitting radioisotope within 5 physical half-lives prior to Day 1 (PYLARIFY imaging) 2. Previous Prostate cancer treatment including radiation, androgen deprivation therapy, brachytherapy, surgery, prostate ablation, hormonal therapies or investigational therapy 3. Known hypersensitivity to the components of PYLARIFY or its analogs 4. Patients with any medical condition or other circumstances that, in the opinion of the investigator, compromise the safety or compliance of the subject to produce reliable data or complete the study 5. Patients who have any radiographic evidence of T3, N1 or M1 disease on SOC imaging (if performed)
