PSMA-PET for Biopsy and Treatment Guidance in Primary Prostate Cancer

Summary

Participation Requirements

Description

This is a prospective, single arm, phase 2 clinical trial. This patient population will have low (1 = Gleason 3 + 3) or intermediate risk (2 = 3 + 4; 3 = 4 + 3) prostate cancer. It will also enroll those who are at high risk of significant prostate cancer (4Kscore >20%, SelectMDx >20%, PSA density >...

This is a prospective, single arm, phase 2 clinical trial. This patient population will have low (1 = Gleason 3 + 3) or intermediate risk (2 = 3 + 4; 3 = 4 + 3) prostate cancer. It will also enroll those who are at high risk of significant prostate cancer (4Kscore >20%, SelectMDx >20%, PSA density >0.15). Patients will be scheduled for magnetic resonance imaging (MRI) as part of routine care for either surgical planning or for further biopsy. Following the informed consent process, patients who enroll in the study will receive a PSMA positron emission tomography (PET) study along with their standard of care (SOC) MRI on an integrated PET-MRI. Registration of PET and MRI will be done using software to generate the PET-MRI images. Patients receiving SOC MRI guided biopsy will receive additional PET guided biopsies as indicated in a single session. The sensitivity and specificity will be evaluated along with the ability of the tracer to inform the treatment planning. Patients receiving surgical removal of the prostate will have a slice-by-slice whole mount analysis to assess the sensitivity and specificity the PSMA PET. Primary Objectives Define the accuracy of 68Ga-PSMA-11 PET-CT for detecting the location and size of clinically significant prostate cancer lesions in low and intermediate risk disease. Secondary Objectives Evaluate how knowledge of the PSMA-PET might inform treatment planning. Exploratory Objectives Generate pilot data for future larger clinical trials
