New PET scan could better spot prostate cancer spread
NCT ID NCT06099093
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a new type of PET scan (18F-DCFPyL PSMA-PET) can show prostate cancer lesions as well as the standard scan (68Ga-PSMA-11 PET/CT) in 30 men with advanced prostate cancer who are receiving a targeted radiation therapy (177Lu-vipivotide tetraxetan). The goal is to see if the new scan is a reliable option for monitoring the disease. Participants will get the experimental scan before starting their standard treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-DCFPyL (a radioactive tracer for PET imaging)
- What this could lead to
- If successful, this imaging method could offer a more accessible or effective way to monitor prostate cancer spread during treatment.
- What could go wrong
- This is a small pilot study (30 people) comparing two imaging scans, not testing a new treatment. The new scan may not prove better or more practical than the existing one.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants must have histologically or cytologically confirmed prostate cancer. * Age ≥18 years. * Participants must be planned for standard-of-care 177Lu-Vipivotide Tetraxetan therapy after the 18F-DCFPyL PSMA-PET. -≥1 PSMA-avid lesion on 68Ga-PSMA-11 PSMA-PET performed within 120 days of study entry (to meet eligibility for 177Lu-Vipivotide Tetraxetan therapy). * Ability and willingness to comply with the study procedures. * Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational agent are eligible for this trial. * The effects of 18F-DCFPyL on the developing human fetus are unknown. For this reason and because radiopharmaceutical agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for 24 hours after the 18F-DCFPyL PSMA-PET scan. * Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria: * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia. * Contraindications to PET/CT, including severe claustrophobia. * History of allergic reactions attributed to compounds of similar chemical or biologic composition to 18F-DCFPyL * Any past or current condition that, in the opinion of the study investigators, would confound the results of the study or would pose additional risk or burden to the patient by their participation in the study.
