New PET tracer could spare prostate cancer patients from repeated biopsies
NCT ID NCT06474806
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests whether a radioactive tracer called 64Cu-DOTA-AE105 can accurately show the aggressiveness of prostate cancer on a PET scan. About 168 men with low- to intermediate-risk prostate cancer will receive the tracer and undergo imaging. The goal is to see if this scan can replace or reduce the need for repeated tissue biopsies during active surveillance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 64Cu-DOTA-AE105 (a radioactive tracer injected into the vein for PET imaging)
- What this could lead to
- If successful, this imaging agent could help doctors determine prostate cancer aggressiveness without repeated biopsies, improving monitoring for low-risk patients.
- What could go wrong
- This is an early-phase trial with only 168 participants, so results may not apply to all patients. The imaging accuracy may not be high enough to replace biopsies yet.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Pathology-verified prostate adenocarcinoma * International Society of Urological Pathology (ISUP) grade 1 to 3 * Localised prostate cancer (N0 and M0 status) (only required for ISUP 3 patients) 1. Newly diagnosed patients: Staging must be performed within 6 months from enrolment into the trial. 2. Active surveillance: N0/M0 at the time of diagnosis and no clinical suspicion of prostate cancer outside the prostatic bed at the time of enrolment into the trial. * Eastern Cooperative Oncology Group (ECOG) performance status 0-2 * Prostate biopsy within 1 to 6 months (patients with a biopsy within the last month are excluded to avoid possible inflammation artefacts on the PET scan) 1. The biopsy can be part of the primary staging, a confirmatory biopsy, or serial biopsy as part of an AS. 2. At least 1 core must be MRI-guided. Exclusion Criteria: * Any prior treatment for prostate cancer (surgery, external beam radiation therapy, brachytherapy, hormone therapy, or chemotherapy) * Chronic prostatitis (any signs or symptoms of chronic bacterial prostatitis or chronic pelvic prostatitis and pain syndrome, or known diagnosis of asymptomatic inflammatory prostatitis) * Acute infections within the prostatic bed or lower urinary tract infections * Participants have inadequate bone marrow, kidney, liver, heart, or lung function:
