A Pilot Study of 18F-DCFPyL-PSMA PET in Patients Receiving 177Lu-Vipivotide Tetraxetan Therapy for Metastatic Castrate-resistant Prostate Cancer
Brigham and Women's Hospital
Summary
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).
Description
This is a one-arm single-stage prospective pilot study to determine how 18F-DCFPyL PSMA-PET/CT can be used as a diagnostic test before treatment with 177Lu-vipivotide tetraxetan, which is an approved therapy for advanced prostate cancer. The U.S. Food and Drug Administration (FDA) has approved 18F-DCFPyL as a diagnostic agent (radiotracer) option for prostate cancer, though it is not specifically approved for participants who are due to receive 177Lu-vipivotide tetraxetan therapy. This research study involves a single PET scan using the imaging agent 18F-DCFPyL and the collection of informat…
