Clinical Trial Summary

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.


Description:

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.

Intervention

Diagnostic Test:
PSMA PET scan
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.
Other:
No PSMA PET
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.
Drug:
18F- DCFPyl Injection
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.

Outcome

Type Measure Description Time frame Safety issue
Primary Detection of Clinically Significant Prostate Cancer Percentage of mpMRI and PSMA PET lesions positive for clinically significant prostate cancer 12 weeks
Secondary Detection of Clinically Insignificant Prostate Cancer Percentage of mpMRI and PSMA PET lesions positive for clinically insignificant prostate cancer. 12 weeks
Secondary Difference in PSMA PET and mpMRI Clinically Significant Cancer Detection Percentage of PSMA PET only (mpMRI negative) and PSMA PET overlapping with mpMRI lesions positive for clinically significant prostate cancer. 12 weeks
Secondary Correlation of PSMA PET intensity with Clinically Significant Prostate Cancer Correlate intensity of PSMA PET lesions with clinically significant prostate cancer. 12 weeks
Secondary Correlation of AI Measures with Aggressiveness of Prostate Cancer Correlate artificial intelligence measurement(s) (miPSMA index) of PSMA lesion(s) with aggressiveness of prostate cancer 12 weeks
Secondary Adverse Events Associated with 18F- DCFPyl Safety - Patients will be monitored for adverse events during injection and for two hours after radiotracer administration. 12 weeks
