A Pilot Study of 18F-DCFPyL-PSMA PET in Patients Receiving 177Lu-Vipivotide Tetraxetan Therapy for Metastatic Castrate-resistant Prostate Cancer
The purpose of this research study is to see how well an imaging test, called 18FDCFPyL prostate specific membrane antigen (PSMA) positron emission tomography (PET), can show the extent of prostate cancer when comparing to 68Ga-PSMA-11 PET/CT (another type of diagnostic scan for prostate cancer).
• 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.
