Brief 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.

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: Ga-68 labeled HBED-CC PSMA Device: Positron Emission Tomography (PET) image combined with Computed Tomography (CT) (PET/CT) Device: Positron Emission Tomography (PET) image combined with Magnetic Resonance Imaging (MRI) (PET/MRI) Phase 2

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.

Arm Intervention/treatment
Experimental: high-risk prostate cancer pre-prostatectomy (preRP) population

Patients with high-risk prostate cancer pre-prostatectomy.

Patients receive Ga-68-HBED-CC-PSMA and then undergo PET/CT or PET/MRI approximately 55-70 minutes later.

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.
Other Names:
  • Ga-68 labeled DKFZ-PSMA-11
  • Ga-68 labeled Glu-NH-CO-NH-Lys(Ahx)-HBED-CC
  • Ga-68 labeled Glu-urea-Lys(Ahx)-HBED-CC

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
Other Name: PET/CT

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.
Other Name: PET/MRI

Experimental: Biochemical Recurrence (BCR) population

Patients with prostate cancer with biochemical recurrence.

Patients receive Ga-68-HBED-CC-PSMA and then undergo PET/CT or PET/MRI approximately 55-70 minutes later.

Experimental: Castrate Resistant Prostate cancer (CRCP) population

Patients with castrate resistant prostate cancer.

Primary Outcome Measures :
  1. The sensitivity of Ga-68 HBED-CC PSMA for the detection of nodal metastasis in high-risk pre-prostatectomy patients. [ Time Frame: one month ]
    Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true- negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Point estimate of the true positive rate and the true negative rate will be calculated with the corresponding 95% confidence interval.

  2. The specificity of Ga-68 HBED-CC PSMA for the detection of nodal metastasis in high-risk pre-prostatectomy patients. [ Time Frame: one month ]
    Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true- negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Point estimate of the true positive rate and the true negative rate will be calculated with the corresponding 95% confidence interval.

  3. The sensitivity of Ga-68 HBED-CC PSMA for the detection of metastatic disease in patients with biochemical recurrence after prostatectomy or radiation therapy. [ Time Frame: one month ]
    it will be assumed that all patients with biochemical recurrence will have active disease, therefore the estimated prevalence will be 100%. Therefore the sensitivity will be determined by the percentage of patients in which positive disease is noted. Point estimate of sensitivity will be calculated with the corresponding 95% confidence interval.

  4. Number of lesions that Gallium-68 labeled HBED-CC PSMA delineates in comparison to conventional imaging in castrate resistant prostate cancer patients. [ Time Frame: one month ]
    The number of positive body regions using conventional imaging and Ga-68 HBED-CC PSMA PET will be compared.
