Can a special PET scan spot returning prostate cancer after targeted therapy?
NCT ID NCT07011342
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a PSMA-PET scan using a radioactive tracer called 18F-rhPSMA-7.3 can accurately detect prostate cancer that has come back after focal gland treatment. About 70 men who had focal therapy for intermediate-risk prostate cancer will receive the scan, and the results will be compared to standard biopsy findings one year after treatment. The goal is to see if this imaging method can reliably identify recurrence without relying solely on biopsies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-rhPSMA-7.3 (a radioactive tracer used in PET scans)
- What this could lead to
- If successful, this scan could become a reliable way to detect prostate cancer recurrence after focal therapy, potentially reducing the need for invasive biopsies.
- What could go wrong
- This is an early-stage study with only 70 participants, so results may not apply to all patients. The scan may miss some recurrences or show false positives.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult males 18 years or older; * Patient must have a pre-treatment MRI; * Patient underwent SOC focal therapy with either focal or hemiablation for the treatment of intermediate risk prostate cancer in the past 9 months prior to enrollment; * Intermediate risk disease as defined by American Urology Academy (AUA)/National Comprehensive Cancer Network (NCCN) guidelines (see Appendix A) * Life Expectancy of 10 years or more; * Underwent standard template biopsy before treatment with a minimum of 2 cores into the MRI visible lesion if lesion was present; * Patient understands the purpose of the trial and procedures required for the trial, and can provide signed informed consent as which includes compliances with the requirements and restrictions listed in the informed consent form (ICF) and in the study protocol; and * Ability to adhere to the study visit schedule and all the protocol requirements, including surveillance imaging and test specimen (blood sample) collection at specified time points. Exclusion Criteria: * Patients under the age of 18 will be considered pediatric patients and will not be included in this study because they are thought to represent a unique population outside the scope of this study as it is aimed at identifying factors that affect adults only. * Patients previously treated with whole gland ablation or prior partial gland ablation over 9 months prior to enrollment.
