Ga-68-PSMA-11 in Men With Prostate Cancer

Utility of Ga-68-PSMA-11 in Management of Prostate Cancer

The purpose of this study is to provide access to Ga-68-PSMA-11 PET for evaluation of male veterans with newly diagnosed or biochemically recurrent prostate cancer. All patients will receive conventional imaging (MRI, CT, and/or a molecular imaging bone scan) as well as Ga-68-PSMA-11 PET in order to evaluate the utility of diagnostic testing in patients with positive PSA status, a comparison of results from conventional imaging and PSMA PET imagining will be performed.

Participants (male veterans) with initial diagnosis of prostate cancer or biochemically recurrent disease that consent to participate in the study will receive both conventional imaging (MRI, CT, and/or molecular imaging bone scan) as well as Ga-68-PSMA-11 PET/CT. Following baseline assessment (Visit #1), Ga-68-PSMA-11 (3-7 mCi) will be administered as a single intravenous administration with PET/CT performed approximately 60 minutes after injection (Visit #2A). At approximately 120 minutes after injection of Ga-68-PSMA-11, the final evaluation for safety and tolerability will occur (Visit #2B)

Inclusion Criteria:

• Able to tolerate PET/CT imaging and one or more of the following:
• Patients with newly diagnosed prostate cancer with primary staging classified at high/intermediate risk per NCCN guidelines OR
• Biochemical Recurrence: Patients with rising PSA after definitive therapy with prostatectomy or radiation therapy or other local therapies

Exclusion Criteria:

• Claustrophobia or any other condition that would preclude PET/CT imaging.
• Any constellation of medical conditions that indicate expectancy of less than one year
