Could a new PET tracer reveal hidden prostate cancer activity?
NCT ID NCT05242744
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new radioactive tracer called [18F]FluorThanatrace (FTT) used with PET/CT scans to measure PARP-1 activity in men with metastatic prostate cancer. Up to 30 participants will have scans before and after starting a new therapy. The goal is to see if FTT can non-invasively show PARP expression, which might help guide treatment decisions in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- [18F]FluorThanatrace (a radioactive tracer for PET scans)
- What this could lead to
- If successful, this could lead to a better way to see PARP activity in prostate cancer tumors using a simple scan, helping doctors choose the right treatments.
- What could go wrong
- This is a small, early-phase imaging study with only 30 participants. The tracer may not reliably show PARP activity in all patients, and it is not a treatment itself.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Participants will be ≥ 18 years of age 2. Histologically proven prostate carcinoma 3. Clinical evidence of metastatic disease with at least one lesion identified on standard of care imaging (CT, MRI, Bone Scan, FDG or other PET/CT, Ultrasound) 4. Considered a candidate for new therapy or change in therapy with PARP inhibitor therapy and/or androgen deprivation therapy (ADT) and/or chemotherapy with or without additional agents, either on a clinical trial or as part of clinical care. 5. Participants must be informed of the investigational nature of this study and be willing to provide written informed consent and participate in this study in accordance with institutional and federal guidelines prior to study-specific procedures. Exclusion Criteria: 1. Inability to tolerate imaging procedures in the opinion of an investigator or treating physician 2. Any current medical condition, illness, or disorder as assessed by medical record review and/or self-reported that is considered by a physician investigator to be a condition that could compromise participant safety or successful participation in the study
