18F-rhPSMA-7.3 for Prostate Cancer
(SCOUT Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a special scan to detect prostate cancer recurrence after focused treatment. The scan uses 18F-rhPSMA-7.3, a radioactive tracer that highlights cancer cells in the prostate, making them easier to see. Men who underwent focal therapy for intermediate-risk prostate cancer in the last 9 months might be suitable candidates. The goal is to determine if this scan can more effectively identify cancer that returns after treatment. As an unphased trial, this study provides a unique opportunity to contribute to research that could enhance future cancer detection methods.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this PSMA-PET scan is safe for identifying recurrent prostate cancer?
Research has shown that 18F-rhPSMA-7.3 is safe for patients with prostate cancer. In studies involving 747 patients, each received one dose of this diagnostic tool without major safety issues. While side effects can occur with any medical treatment, the FDA approval of 18F-rhPSMA-7.3 for detecting prostate cancer suggests it is generally well-tolerated. This indicates that in past research, serious side effects were likely rare or manageable. Patients should consult their doctor to understand what this means for their individual situation.12345
Why are researchers excited about this trial?
Researchers are excited about 18F-rhPSMA-7.3 because it offers a new way to detect prostate cancer that targets the prostate-specific membrane antigen (PSMA). Unlike traditional imaging methods, which might miss smaller or less active lesions, this technique uses a radiohybrid approach to highlight cancer cells more effectively. This means it could help doctors find and treat prostate cancer more accurately, potentially leading to better outcomes for patients. Furthermore, it is administered as a simple intravenous injection, making it a convenient option for both patients and healthcare providers.
What evidence suggests that this PSMA-PET scan is effective for identifying recurrent prostate cancer?
Research has shown that 18F-rhPSMA-7.3, which participants in this trial will receive, effectively detects recurrent prostate cancer. Studies have found it can identify cancer in 83% of patients tested, reliably locating cancer cells with a specific marker called PSMA. The FDA has already approved this scan for detecting cancer in men with prostate cancer, supporting its ability to find cancer that returns after treatment. Overall, it is a promising tool for those with recurrent prostate cancer.36789

Are You a Good Fit for This Trial?
This trial is for adult males over 18 with intermediate risk prostate cancer who had focal therapy within the last 9 months. They should expect to live at least another 10 years, have a pre-treatment MRI, and be able to follow the study schedule including imaging and blood tests. It's not for those under 18 or treated with whole gland ablation more than 9 months ago.Inclusion Criteria

Trial Overview
The trial is testing the effectiveness of a new PSMA-PET scan called 18F-rhPSMA-7.3 in detecting recurrent prostate cancer after patients received focal treatment aimed at only part of the prostate.

Experimental Treatment
Patients will undergo a PSMA-PET scan at 1 year (+/- 60 days) after treatment with SOC focal therapy using a radiohybrid Prostate-Specific Membrane Antigen (rhPSMA)-targeted PET scan using 18F-rhPSMA-7.3 (Posluma). The rhPSMA-targeted PET scan is an FDA-approved PET scan to detect the presence of lesions positive for prostate-specific membrane antigen (PSMA) in men with prostate cancer. 18F-rhPSMA-7.3 (Posluma) injection is a radioactive diagnostic agent that is administered in the form of an intravenous injection.
