New scan could reveal hidden spread of prostate cancer
NCT ID NCT06074510
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study is testing whether a special PET scan using PYLARIFY can find prostate cancer that has spread beyond the prostate in men with favorable intermediate risk cancer. About 274 men will receive one injection and scan, then be followed for up to a year. The goal is to see if the scan detects cancer that other tests miss, which could help guide treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Piflufolastat F 18 (PYLARIFY injection)
- What this could lead to
- If successful, this could help doctors more accurately determine if prostate cancer has spread, leading to better treatment choices for men with favorable intermediate risk prostate cancer.
- What could go wrong
- This is a phase 4 imaging study, not a treatment trial. It may not change outcomes for all patients, and false positives or negatives are possible. Results are limited to detection, not cure.

Inclusion Criteria: 1. Patients must have the ability to understand and sign an approved informed consent form (ICF) 2. Patients must have the ability to understand and comply with all protocol requirements 3. Patients must be ≥ 18 years of age 4. Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 5. Patients with life expectancy of at least 13 months as determined by the investigator 6. Patients must have confirmed favorable intermediate risk (FIR) adenocarcinoma of the prostate per 2023 NCCN guidelines. FIR risk group confirmation includes all the following: * 1 intermediate risk factor (cT2b-cT2c or ISUP Grade Group 2 or PSA 10-20 ng/mL) * ISUP Grade Group 1 or 2 * \<50% biopsy cores positive (e.g., \<6 of 12 cores) Note: Date of the prostate biopsy should be no sooner that 2 weeks and no later than 3 months prior to PYLARIFY PET imaging 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)
