Prospective, randomized, phase 2 clinical trial to determine if PSMA PET imaging plus mpMRI improves detection of clinically significant prostate cancer as compared to mpMRI alone.
This a prospective, randomized, phase 2 clinical trial. We will enroll patients who underwent mpMRI of the prostate as part of their standard clinical care, have PI-RADS 4, or 5 lesion(s) on mpMRI, and are scheduled to undergo fusion guided prostate biopsy. Subjects that sign the consent form will be randomized to undergo DCFPyL PET/CT imaging or no PSMA PET imaging prior to the prostate biopsy. In the PSMA scan cohort, decision for biopsy targets will be made based on the combination of the findings of mpMRI and PSMA scans. In the no PSMA scan (control) group, the biopsy will be performed based on mpMRI findings. Each patient will undergo 12 core systematic biopsy as the standard of care. Two additional biopsies for each mpMRI and PSMA PET and overlap lesion will also performed.

Subjects will undergo DCFPyL PET/CT imaging and mpMRI imaging prior to the prostate biopsy. The decision for biopsy targets will be made based on the combination of the findings of mpMRI and PSMA scans. The intervention includes a mpMRI, a PSMA PET scan, and a prostate biopsy.
Subjects will undergo mpMRI imaging prior to the prostate biopsy. These subjects do not undergo a PSMA PET scan prior to the prostate biopsy. The decision for biopsy targets will be made based on the findings of mpMRI. The intervention includes a mpMRI and a prostate biopsy.
DCFPyL is a PSMA imaging ligand that was developed to enhance the detection of small lesions in the prostate or other pelvic areas. 18F- DCFPyl Injection will be administered prior to the PSMA PET/CT via an in-dwelling catheter placed in an antecubital vein or an equivalent venous access under the direct supervision of study personnel.
