Prostate Cancer Clinical Trial
Gallium-68 PSMA-11 PET in Intermediate to High-risk Preprostatectomy Patients
Summary
The investigators are imaging patients with prostate cancer using a new PET imaging agent (Ga-68-PSMA-11) in order to evaluate it's ability to detection prostate cancer in patients with high risk disease prior to prostatectomy.
Full Description
Imaging and staging of prostate cancer is critical for surgical and treatment planning. Patients with suspected metastatic prostate cancer will be imaged using Gallium-68 labeled PSMA-11 in order to demonstrate its utility. The investigators plan to utilize this data to obtain further approvals of the Ga-68-PSMA-11 compound, so that this agent will become available for clinical imaging in prostate cancer patients. In the pre-prostatectomy population, the primary objective is to determine the sensitivity and specificity for detection on nodal metastasis.
This compound has been shown to be superior to choline based PET agents for the staging of prostate cancer, both Carbon-11 and Fluorine-18 compounds. But this compound was not patented and therefore no company or private entity will make the investment required to bring Ga-68-PSMA-11 to market. In the vacuum of availability, academic groups must take the lead in order to collect the necessary data for future FDA approval.

Exclusion Criteria:
Patients not capable of getting PET study due to weight, claustrophobia, or inability to lay still for the duration of the exam.
Neoadjuvant chemotherapy or radiation therapy prior to prostatectomy.
Including focal ablation techniques (HiFu).
Androgen deprivation therapy or other neoadjuvant treatments prior to PET imaging and surgery.
