Summary

The investigators are imaging patients with prostate cancer using a new PET imaging agent (Ga-68 HBED-CC PSMA) in order to evaluate it's ability to detection prostate cancer in patients with high risk disease prior to prostatectomy, patients with biochemical recurrence and patients with castrate resistant prostate cancer.

Detailed 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 HBED-CC PSMA in order to demonstrate its utility. The investigators plan to utilize this data to obtain further approvals of the HBED-CC PSMA compound, so that this agent will become available for clinical imaging in prostate cancer patients. 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 HBED-CC PSMA to market. In the vacuum of availability, academic groups must take the lead in order to collect the necessary data for future FDA approval. This study focuses on three patients populations that are imaged. In the pre-prostatectomy population, the primary objective is to determine the sensitivity and specificity for detection on nodal metastasis. In the biochemical recurrence population, the primary objective is to determine the sensitivity of recurrence location. In the castrate resistant prostate cancer population the primary objective is to determine if PSMA PET detects more metastatic lesions than conventional imaging.

Conditions

• Prostate Cancer

Interventions

Type	Name	Description
DRUG	Ga-68 labeled HBED-CC PSMA	The imaging agent (Ga-68 HBED-CC PSMA) will be administered on an outpatient basis. It will be administered a single time intravenously prior to the PET/CT imaging. The one-time nominal injected dose will be 3 to 7 millicurie (mCi) containing 10 - 25 μg Ga-68 HBED-CC PSMA.
DEVICE	Positron Emission Tomography (PET) image combined with Computed Tomography (CT) (PET/CT)	Patient shall begin imaging between 55 and 70 minutes after the injection of the radiopharmaceutical. A PET/CT scan includes two parts: a PET scan and a CT scan. The CT portion of the scan produces a 3-D image that shows a patient's anatomy. The PET scan demonstrates function and what's occurring on a cellular level. The PET scan is unique because it images the radiation emitted from the patient while the CT records anatomical x-rays, showing the same area from another perspective
DEVICE	Positron Emission Tomography (PET) image combined with Magnetic Resonance Imaging (MRI) (PET/MRI)	Patient shall begin imaging between 55 and 70 minutes after the injection of the radiopharmaceutical. A PET/MRI scan is a two-in-one test that combines images from a positron emission tomography (PET) scan and a magnetic resonance imaging (MRI) scan. Coverage for the scan will extend from the patients vertex through the mid thighs. We will use 4 minute acquisitions per bed position for PET imaging.
